Will LED Lights Harm Dogs’ Eyes?

Will LED Lights Harm Dogs’ Eyes?

Overview What may cause problems for your dog's eyes? Flashing Light Look Directly Improper Use of LED Toys Ultraviolet Light Blue Light Spectrum Pre-existing Eye Disease Tips for Choosing LED Lights for Dogs Low Blue Light Emission Using Dimmable LEDs Creating a Cool Environment Inside Your Dog's Shelter Using Smart LED Lights Investing in Quality LEDs Accurate Installation of Lights Consider these before buying LED lights for your dog    Last Update 23th April, 2024   Overview LED lights are the most popular lighting technology today, but are they safe for dogs? Or are dog eyes as sensitive to light as human eyes? As a dog owner or dog lover, it is important that you know the details of LED lights to protect your dog's eyes.    What may cause problems for your dog's eyes? Flashing Light LED lights do not flicker like fluorescent bulbs. However, cheap LED lights may have this problem. Repetitive and rapid flickering of lights may cause eye irritation in dogs. Sometimes overexposure can cause some major problems. Flashing lights may trigger seizures in epileptic dogs. This can lead to a variety of neurological problems. It occurs due to the increased stimulation of the visual cortex of the brain by rapid flashes of light. The neurological effects of flashing lights are not just for dogs. It affects humans as well.   Look Directly Sourcing products from a reputable LED light manufacturer is a guarantee of safety. Nonetheless, it's important to make sure your dog isn't constantly staring at a bright LED light. Moreover, industrial lights and car headlights can irritate and permanently damage your dog's eyes. Therefore, you must ensure that your pet is not exposed to such lights for long periods of time. In addition, your pet should have a designated space to avoid direct exposure to light. It is also advisable not to place your dog's bed directly underneath the light fixture.   Improper Use of LED Toys LED dog toys are becoming increasingly popular with customers. These toys are designed for throwing and catching balls and come with flashing lights to attract a dog's attention. However, these toys can sometimes be unhealthy for dogs. Therefore, if you decide to buy one, make sure it is safe for your pet.   Ultraviolet Light Some LED lights may emit a small amount of UV light. The coating on the LED chip usually blocks most of this. However, some blue LED lights still emit a small amount of UV. While these lights are usually safe for your dog, it's best to avoid using them if you want to be extra careful.   Blue Light Spectrum Like humans, dogs' eyes can be damaged and negatively affected by blue light leakage. Simply put, blue light has a shorter wavelength than the wavelengths of other colors of light we can see. This means that it can penetrate deep into our eyes. Because of this, it can affect the health of the cells in the back of our eyes (called the retina). This condition is called blue light toxicity. As a result, spending a lot of time around blue light may make your eyes uncomfortable. Sometimes, it can even lead to vision impairment, redness and swelling of the eyes, but this doesn't happen very often. The extent to which it disturbs your eyes depends on the intensity of the light and the amount of time you spend around it. Also, similar to humans, dogs have a circadian rhythm, which provides their bodies with information about when to wake up and go to sleep. It runs on sunlight. Like the sun, blue light works in a similar way. As a result, when your dog is under blue light, it can become frustrated and upset. More specifically, blue light can break a dog's nocturnal habits. Additionally, studies have shown that prolonged exposure to the color blue can affect a dog's physical and mental health. But best of all, the blue light emitted by LED lights is negligible compared to traditional lights. However, you need to follow your dog's specific bedtime. Keep in mind that the brightness of the lights should not be too harsh during bedtime. Therefore, you can also take your dog for a walk before bedtime. If you want to use lights where your dog is, choose lights with longer wavelengths. For example, amber or orange light has longer wavelengths than those visible to the naked eye.   Pre-existing Eye Disease You must be more careful when your dog has existing eye problems, cataracts or corneal ulcers. These conditions are more sensitive to damage caused by LEDs.    Tips for Choosing LED Lights for Dogs Low Blue Light Emission Prolonged exposure to blue light can cause eye strain and discomfort. For this reason, it is best to use LEDs with a low fused discharge. Today, LEDs provide a small amount of blue light because they contain filters and screen protectors that reduce the brightness of blue light.   Using Dimmable LEDs You can use dimmable LED options to adjust the lights and create a comfortable atmosphere for your dog's eyes, especially at night. In addition, using LED light strips can improve the environment of your dog shelter. Thus, with the dimmable option, you can customize the brightness of the LED strip.   Creating a Cool Environment Inside Your Dog's Shelter You can try warm white and amber colors for a calming effect as they mimic sunlight and provide excellent visibility. Amber and orange lights are known for creating a relaxing atmosphere. Therefore, as a homeowner, you need to know to ignore nighttime lighting. Otherwise, it will make your dog's eyes start staring.   Using Smart LED Lights When choosing smart LED lights, you can consider these remotely with the help of a mobile app. This way, you can adjust the brightness and color of where they are located. Some lights have specific sensors that turn on when a dog is near. Connecting the LED lights to your phone is very simple. Therefore, you can use Bluetooth or Wi-Fi. Just follow the company's instructions for proper pairing.   Investing in Quality LEDs Choose good LED lights for safety. Get them from a trusted and experienced manufacturer. Look for certificates that prove that the lights are safe and of good quality. Therefore, always make sure that the lights you buy are certified for safety.   Accurate Installation of Lights Always keep in mind the height of your dog house when installing LED lights in it. Don't end up installing bulky fixtures in a small pet house. It's best to hire a professional to install built-in fixtures in the house so that there are no hanging lights to hurt your dog as they move around. Also, keep in mind the proper wiring.   Consider these before buying LED lights for your dog  1. Find Dog Safety LED Signs When purchasing an LED light, check to see if it carries the dog safety symbol. This indicates that the lights have been tested and are safe for dogs.  2. Comparative Lighting If you have different types of lights in your home, you can check them out to see which ones are best for dogs. Usually, LED lights that are not too bright and have a wide range of light distribution are safe for dogs. 3. Check Strength You can also check the brightness of the LED lights. If they are brighter than a 60-watt bulb, they may not be safe for dogs. 4. Thermal Emission Prevent the risk of burns by choosing an LED light that emits the least amount of heat. Low-heat options are safer, especially if the lights are located in an area where your dog has direct access. 5. Compatibility with Dimmers If you intend to use LED lights in a variety of settings, check that they are compatible with the dimmer switch. This feature allows you to adjust the light intensity to suit different environments and your dog's preferences. 6. Contact Manufacturer If you want to make sure that your LED lights won't hurt your dog, you can contact the company that makes them. They should be able to let you know if their lights are suitable for your dog's eyes.   End.   If you got any question please contact us by E-mail: info@lunrlighting.com
Do You Know How Stained Glass is Made?

Do You Know How Stained Glass is Made?

Overview Section One. What it is? Section Two. Characteristic Section Three. Producing Medieval production methods Modern Method Some final processes   Last update on 1st Jan, 2024   Overview Glassmaking is a magical and fascinating process. Mixtures are hot-melted, blown, forged, and polished to reveal a myriad of strange shapes, and the addition of metals or organics gives the glass a variety of stunning colors. Now we are revealing the process of making raw stained glass.     Section One. What it is? Stained glass is a need to rely on light to express their own a special glass material, known as the dance with the spirit of light, since ancient times is the landscape space in the most artistic expression of the material.   Warm sunlight is projected into the room through the "Rose Window", and the dappling of light and shadow is reflected through different colors, which makes it look like a holy realm, and it seems that you can listen to the voice of God from a close distance.   The thickness of the original color glass is usually about 3mm, the surface of the glass is uneven and most of it is textured, and there will be air bubbles inside the glass. Its color is made by adding special pigments fired during the production process, so all the cut surfaces are guaranteed to have the same color, and the products made of it will never fade and will remain unchanged for hundreds of years.     Section Two. Characteristic Different from the general tinted glass (ordinary white glass on the coloring process), stained glass raw pieces need to be melted at high temperatures of more than 1,600 degrees furnace temperature, after annealing, the formation of colorful and colorful colors, not only will never fade, but also the color of each section of the surface to maintain consistency with the surface, which can be referred to as the original glass, the original glass, the color glass.   Section Three. Producing Medieval production methods In the Middle Ages, glassworks were often built with large supplies of silicon. This material melted at very high heat, and lead-like materials were added to lower its melting point, and then lime-like substances were added to stabilize the molten glass.   While the glass is still molten, adding metal oxide powders to the mixture creates a variety of colors. For example, cobalt can be used to produce blue glass, chromium and iron oxides can be used to produce green glass, and gold can be used to produce ruby-colored glass.   When mixing gold chloride and molten glass to produce red shifts, these artists are actually doing something similar to what nanotechnologists do. The mixture produces tiny spheres of gold that absorb and reflect sunlight and thus display a deep red color.     In the next step of production, there are several different ways to handle the molten glass. Let's start by discussing two different methods of producing ancient stained glass windows: blackout glass (also known as "hand-blown" cylinders) and corona glass.   To make blackout glass, a blowpipe was used to dip a ball of molten glass from a pot that was being heated in a furnace. Once the proper shape is formed, an air bubble is blown into the molten glass. A metal tool is then used to shape the mass of molten glass into a long cylinder, and this step is repeated when the molten glass is reheated. At this stage, the bottom of the cylinder is removed and the molten glass is cooled to the desired shape. After opening one end of the cylinder, the glass is placed in a different furnace, heated and flattened, and then cooled in an annealing furnace.   Meanwhile, in the manufacture of corona glass, an air bubble is blown into a mass of molten glass. The mass is spun by hand or on a table similar to a faience spinning wheel. The molten air bubble would unfold and flatten with the force of the rapid spinning, and the glass could then be cut into small pieces. While this hand-blowing method is still used in glassmaking today, it would not be used for large-scale stained glass production.   Modern Method A more modern method of producing colored glass is pressed glass. In this technique, molten glass is poured onto a metal or graphite table. A large metal cylinder is then used to roll the glass into a piece, which can be done by hand or machine, and then annealed. The technique was first commercialized in the mid-1830s and is still widely used today.     Some final processes In the past, the artist would create a small-scale model for the final design. In the Middle Ages, such drawings would have been made directly onto a washed table surface on which the window would have been cut, drawn and assembled. The overall pattern of the window was divided into smaller pieces, and this small-scale design would serve as a template for each small piece of glass in the overall window pattern.   Once the design is complete, the individual colors of glass are cut to match the selected location. Over the years, a variety of drawing and coloring techniques have been developed in hopes of further improving the design of stained glass. For example, silver nitrate tinting produces a yellow color that can help improve borders and halos, and a tinting called Cousin Rose has been developed that allows artists to better represent the tones of the human body.   In the final step, separating strips called inserts, previously lead, but more recently copper, are added to the window pieces. The joints are then soldered together and oil-based cement is embedded between the glass and the divider to ensure stability and minimize possible shaking.     End     If you have any question please contact info@lunrlighting.com to get more details.
Do You Really Know How to Select A High-CRI Lights?

Do You Really Know How to Select A High-CRI Lights?

Overview First thing you need to know CRI in layman's terms Easy to be misunderstood Simply pursue high CRI Methods to stimulate high CRI About the spectrum of excellent high CRI Individual values of the spectrum The importance of red light Conclusion   Last updated 24th May, 2024   Overview The sun shines on the most things in the world, but there are always places where the sun doesn't reach, so human invented the lamp.   First thing you need to know The light emitted by a lamp shines on an object and it reflects light that cannot be absorbed back to our eyes, which makes it visible. These so-called rays of light are actually electromagnetic waves, some of which have longer wavelengths and some shorter, and generally electromagnetic waves with wavelengths between 400nm-750nm can be seen by our human eyes.     A portion of the wave spectrum of sunlight, which is used as a standard wave spectrum, is shown in the figure below, and our goal is to make a light source that emits light that is infinitely close to this spectrum.     CRI in layman's terms Therefore, we used a metric: CRI, to assess the gap between our artificial light and the standard wave spectrum. We define that the color of an object is most realistic when sunlight hits it, cause sunlight contains all of the visible spectrum that the human eye can see. It has a CRI value of 100, and we use it as a benchmark to compare how good or bad other light sources are. The higher CRI of the light, the better ability to reproduce colors.   In the lighting field, we generally believe that CRI greater than or equal to 90 is a high color rendering emitter. The light emitted by this luminescent body makes objects more three-dimensional, clearer and reduces visual fatigue.     Easy to be misunderstood In recent years, high CRI lamps are very hot sale and many people use it as an important indicator when they select lights for their home. But if you judge a lamp is good or bad by only CRI, it is easy to make a huge mistake.   Simply pursue high CRI The first thing is high CRI not means high color temperature. A simple example is that the color of sun’s rays is different from morning to evening, but the CRI is all the same. That’s because the color you can see depend on what color reflected by material, though the sunlight contains waves of all colors, the material doesn’t reflect it. Two light colors are the same but not necessarily the same spectrum.   You can see we can mix various colors to get a 5000K light, and it doesn’t have red light, so you'll see distorted colors.     If you light up the apple with a red color wavelength, obviously you will see full color.     Methods to stimulate high CRI The second thing people often misled by manufacturers is that how they excite phosphor. Usually the light source is blue light excitation or violet light excitation. In fact they both good in terms of current technical.   The defects of blue light excitation are that it is very ineffective in suppressing short-wave blue light, the wavelength is still much higher than that of the solar spectrum, the indigo portion has not yet been made up, and there is a lack of color rendering in irradiated items, which makes it difficult to influence melatonin. The drawback of violet light excitation is that while the excitation process reduces the stimulation of short-wave blue light, it may brings the danger of UV damage.   But these shortcomings can be overcome with current technology. So we don't need to buy blue-excited or violet-excited lights specifically. If the manufacturer of the fixture you are buying has expert support, you can ask them for more detailed information. I will summarize the criteria for a really good high CRI light below.   About the spectrum of excellent high CRI Individual values of the spectrum The waveform of the light source should be uniform with no prominent peaks or valleys. Pay particular attention to the R9 value and the waveform outside of visible light. Ra index better be higher than 90, at least higher than 80. Notice that Ra index mean the average value of R1-R8, you may be wondering why the R9 is not included? Actually the calculation of CRI is the average value of R1-R15, but we have used the value of R1-R8 in the past. These are soft color and enough to evaluate color performance in areas such as clothing or architecture but obviously not available for some other aspects like art exhibitions, meat color, etc. So new standard of CRI calculation comes out.   Now Ra means the average value of R1-R8, CRI means the average value of R1-R15. R9-R15 are more saturated colors. One of these, R9, is the saturated red color, which has a special value and describes the specific ability of light to accurately reproduce the red color of an object, many manufacturers do not indicate the scores of R9.   The importance of red light However, many application scenarios require red light, such as film, textile printing, image printing, medical lighting, and art lighting. Some things don't look red but are made up of many colors, such as your skin, which is affected by blood under the skin and therefore skin tones include red, if the light you buy has a low R9 value it means that when you shine this light on your skin it will look like you have pale skin.   So the problem is that some people still used the old standard, which mean maybe their light have very low R9 value but they still claim to have a 90+ CRI of light. It will brings the consequence that when you buy a 90+ CRI light and use it to light up your room, work or something, then you find out they are pale, maybe even a bit green.     Conclusion Now let’s conclude how CRI effect the decision when you buy a lighting. What we need is that are as close to the sunlight spectrum as possible, of course normally we do not need other than visible light, such as ultraviolet or infrared, in our daily lighting. Excessive UV rays can damage our skin and eyes. The benefit of high CRI lighting is that the indoor scene closer to the outdoor effect, and the objects are more realistic, clear and plump.   We try to explain the significance of some important parameters in lighting in as simple and understandable terms as possible.
