What is anti glare ceiling light and How to Reduce Light Glare?
What is glare ?
Glare is an unhealth lighting phenomenon.
Glare is caused when the brightness of the light source is extremely high or when the brightness difference between the background and the center of the field of view is large.
There are two forms of glare， direct glare and reflective glare.
The glare caused by high brightness light source directly into the human eye is called direct glare.
Glare caused by a light source reflecting off a shiny surface into the human eye is called reflected glare.
Therefore, in the interior lighting design, in addition to limiting direct glare, attention should also be paid to avoid the reflection glare caused by high-gloss decorative materials (such as mirrors, stainless steel, etc).
Is glare bad for your eyes?
The phenomenon of “glare” not only affects viewing, but also has an impact on visual health. Glare is one of the important causes of visual fatigue.
How to effectively reduce glare is the lighting industry has been committed to research.Most people now spend 90% of their time working and living indoors, indoors is not enough sunlight.So most of the time indoors is the need to turn on the light to illuminate. Choosing the right lighting products is important.
With the attention of human health, the market demand for anti-dazzle lamps is also increasing, so as a wholesaler or importer , the anti glare light as a Must-have product, it is particularly important. This will not only make your products more responsive to market needs and provide new growth points for your business, but also improve your product range. In addition you can improve your brand professionalism.
Next, I will summarize the matters that you need to pay attention to when choosing anti-glare lighting through the introduction of anti-glare lighting.
What is anti glare downlight
Strictly speaking, there is no anti-glare lighting that is completely anti-glare. Any light is blinding when looked directly at.
In the sense of look,anti glare lights can reduce the direct light to people’s eyes, so that the eyes can not feel the glare of the light.
In numerical terms, an anti glare downlight is with an URG of less than 13.
From a structural point of view, anti-glare lighting are with deep light sources or anti-glare optical accessories.
What is an anti-glare downlight?
The anti glare downlight is mainly through the use of optical accessories or deep light source design in the structure to reduce the direct light of the lamp to the eyes, so as to achieve anti-glare, provide users with healthier lights, and create a good indoor lighting space atmosphere for users.
Below is a comparison photo of normal lighting and anti-glare lighting.
Then we will explain in detail for this two major anti glare way, to let you understand in the manufacturers or factories are through what way to reduce the anti-glare
How do anti glare downlights work?
anti glare spotlight is through optical design, from the optical Angle to change the refraction of the light, reduce the direct light to the eyes, so that the light becomes soft, and let the person can not feel or see the glare.
How to reduce glare from overhead lights?How do I reduce spotlight glare?
First ,Let the light source is deep , Increased the light‘s shading angle.
The deep hole design is to increase the distance of the light source to the ceiling and let the light source is deepper so as to enlarge the shading Angle and reduce the direct light to the eyes.
The deeper the light source, the better the anti-glare function. Compared with normal lights, the anti-glare light with a deep structure of the light source ,the light is higher, which will also cause the following two types of problems
1 The deeper the light source, the higher the total height of the lamp, so the thickness of the ceiling must be thicker.
For commercial residential buildings, most of the floor height is about 2.8 meters, the ceiling thickness of such residential buildings is generally 12 to 15 centimeters, and the height of lamps is generally less than 11cm.
In order to meet this demand, professional manufacturers will try to control the height of the lamp while achieving anti-glare function.The anti-glare light’s light source is deep inside 30-70mm, which can achieve a good anti-glare effect, and the height of the lamp body will not more than 11cm.
In the decoration industry, the thickness of the ceiling is pursued as small as possible, so that the indoor space under the ceiling is larger and the space is better. For this reason, in the lighting industry, manufacturers are also constantly pursuing shorter light fixtures.
2, the deeper the light source, the better the anti-glare effect, the more serious the light loss, the more brightness is lower.
As an importer or wholesaler or engineer, when choosing a deep-hole anti-glare structure, in addition to considering the anti-glare function, but also the height and brighttness,Then we can provide the end user with a more professional and energy-saving anti-glare lamp.
Two: Use optical accessories to make the light anti-glare.
As far as the current lighting market is concerned, there are the following types of anti-glare optical accessories
1) Anti-glare lens
Anti-glare lens is throughed accurate light control, let out more uniform light at the same time to achieve anti-glare effect,
Anti-glare lens is mainly used in LED integrated lamps,it is rarely used in GU10 MR16 bulbs
frosted flood plate or frosted glass, which makes the light softer and directly reduces the glare of the light,
2) Frost floodlight or frost glass
Because some LED lights and bulbs, there is no lens, but there will be a flood plate, the flood plate made of frosted, can also achieve a certain anti-glare effect.
As a downlight fixture buyer, you can also choose to make the glass of the lamp frosted to reduce glare.
3) Black reflector cup
Black can absorb light, Used black reflector cup , while refracting light, absorb other stray light, so as to effectively reduce light leakage and achieve anti-glare effect.
The following is the effect of the white reflector cup and the black reflector cup, as can be seen from the figure, the lamp with the black reflector cup can be a good anti-glare, and cannot see the glare
What’s more, there are two kinds of black cup, gun metal reflector cup and matte black reflector cup
If the matte black reflector cup is used on the lamp, the glare will still be seen near the matte black reflector cup outlet, but gun metal reflector cup will not.
Gun metal reflector cup is more anti-glare and looks better than matte black reflector cup
Below is the comparison diagram of gun metal reflector cup and matte black reflector cup
What’s more, there are two kinds of black cup, gun metal reflector cup and matte black reflector cup
If the matte black reflector cup is used on the lamp, the glare will still be seen near the matte black reflector cup outlet, but gun metal reflector cup will not.
Gun metal reflector cup is more anti-glare and looks better than matte black reflector cup
Below is the comparison diagram of gun metal reflector cup and matte black reflector cup
4)Honeycomb anti-glare
What is a honeycomb
Honeycomb is a special three-dimensional metal sheet, usually black, but also white, but black is more common (below)
What does honeycomb do to lights?
The honey comb is added in front of the GU10 bulb or LED chip, the light is evenly divided into a number of small areas, disperse the main light column, weaken the central light intensity, so that the intensity of the light and impact strength is reduced, and the peripheral light is emitted to the three-dimensional side of the honeycomb, and Reduce random reflection of light by blocking.
On the one hand, the uniform distribution of the three-dimensional cellular network also blocks the large area of glare generated by the luminous surface of the spotlight].
On the other hand, the human eye from the side of the lamp, basically blocks the glare of the light outlet, achieving the anti-glare of the lighting.
Kingda light have a series honeycomb GU10 downlight fixture.Please clip below photo to know more about it
Note: if the light is with honeycomb, please try to do not install near the wall, because it will hit the shape of the honey comb to the wall, so the light spot will not look good.
These are the most conventional anti-glare methods in the lighting industry, and there are also two or more anti-glare methods used in superposition.
anti glare spotlight make the light softer and reduce the direct light to the eyes, but it also reduced brightness and lumen.
Therefore, we can not blindly pursue too much anti-glare, to superimpose the use of a variety of anti-glare methods, thereby increasing the light loss, waste the brightness, which is contrary to the general direction of the lighting market to pursue energy saving and environmental protection.
In normal, the downlight is used one or two anti-glare methods, the anti-glare function is good enought.
Kingda Lighting has been committed to the development of anti-glare GU10 lamp, in the synthesis and measurement of various anti-glare methods, and taking into account the needs of the actual market.Kingda lighting try to minimize light loss while providing users with anti glare lights concept for the purpose, constantly in the development of a series of anti-glare good and light loss less anti-glare GU10 lamp shell, no matter what kind of light bulb you choose. After using anti glare lights of kingda lighting, it can also achieve a good anti-glare effect.
Choose the anti-glare downlight from kingda lighting, Kingda lighting will not only provide healthy lighting to your end-user, but also bring market demand and cost-effective products.
