The following is the speech summary of "dazzle solution for health education lighting -- technical introduction of anti-dazzle sheet film material" by ma zhanhui, executive vice general manager of jiangxi shenghui optical technology collaborative innovation co., LTD. :

The previous two professors Shared a lot of professional knowledge and ideas with you. We are a material manufacturer, and we share some technical development and application problems of glare material that we are concerned about.

We know from the customer some requirements for lighting, there are about 6 aspects.1. Pay more attention to illumination and uniformity of illumination.Two, brightness, in our regular grayscale and brightness, but it is required to an appropriate value, does not need to be high, also does not need to be too low.Control of glare to avoid direct glare.Four, color rendering index, the higher the color rendering index, the closer to our natural and real environment.Five, color temperature, need a comfortable color temperature.Vi. Power supply.

The influence that illume pair of eyesight and harm, we also summarized a few respects: the first is illuminance, illuminance is inferior.The second is the uniformity that the two teachers talked about;The third is the color rendering index, in the LED light, now everyone do higher, but in the traditional lighting, it may be less;The fourth is the energy consumption of electricity, the fifth is a harm of glare.We believe that high quality lighting should improve the efficiency of learning. The purpose of students in the classroom is to learn. We hope that our lamps can play an auxiliary and helpful role in improving the learning efficiency of students.

When we do glare, we usually do it in a couple of ways: one is the same way we do traditional grille lights, with this kind of blocking.There are two kinds of barriers, one is to reflect the light, and one is to absorb the light.The second is the optical material control that we have on the market today.The idea is to do optical microstructures on the surface of materials.The third way, the above two ways can be combined, because the two ways have their own advantages and disadvantages.

We do anti-glare materials, the basic principle is through the refraction of light, to change the transmission route of the light, to achieve such a control of glare.As you can see, the first one is the active one, and when that light ray is at a large Angle, it's deflected at a very small Angle.Direct glare is mainly a large Angle of light control problem.The second is the function of anti glare of these materials, it is through the refraction of light, the light of the large Angle converging to the middle, and through this principle to reduce to reduce glare, the end result was the light of large Angle decreases, converge to the middle of the light, that this approach can increase the brightness of the center, that is to say, will improve us light in the area we need illumination or the transmission, without great loss.

Since the material is used to prevent glare, what properties of the material contribute to the anti-glare function?There are five aspects, the transparency of the material itself, the refractive index of the material, and the third is the structure, the precision design, your Angle, including your radian design, including what the result of your processing is, and the life of the material, and finally the size of the structure, it also varies.

Transparency.Inside the transparent material, the light can be conducted in accordance with our basic principle of light refraction, but if the material is atomized, or turn yellow, then the light inside the material will not be carried out in accordance with the us light conduction principle to, it will become a scattering, after scattering, it will have no this function, the control of light it up less than the effect of anti glare.

Index of refraction.The magnitude of the refractive index, the material that has a high refractive index, still has a relatively high deflection efficiency on the light, so this is the refractive index, and if you have a small refractive index, the deflection is going to be lower.

Three, the stability of the structure.We do a demonstration with conical, we according to the strict geometry processing, we can very good control of the conduction of light, if the structure of the manufactured products do not meet our geometric design structure, that we can not achieve the light control, that is to say on the glare of the effect also will not achieve the ideal effect.

Life of materials.Our products are very complete and last for three or five years.Whether it's spotlights or our natural environment, if it's optically stable, we'll see that it's better set up, and it'll keep its control over the distribution of light, and it'll keep its anti-glare function.If the material has poor heat resistance, it may produce two results. The first result is that the material becomes atomized, and the second result is that the optical structure deforms, making its anti-glare function disappear.

Five, the size of the structure.For this large size, it could be anywhere from 6 to 100 pieces per square centimeter, and for smaller structures, it could be anywhere from 2,500 to 22,000 pieces per cubic centimeter, and more.The difference is that this little structure, the same little structure, it's not the same per cubic centimeter, it's going to increase the efficiency of light control, it's going to increase the efficiency of light control.

There are two kinds of lamps and lanterns commonly seen now, one kind is straight luminescence, one kind is to have the function of side luminescence.Light above is to have an expansion function, plus anti-glare diaphragm, may have doubts, why not use an anti-glare diaphragm to achieve this function?As you can see from the previous introduction, the anti-glare diaphragm is to change the light through light refraction, to control the glare.What are the characteristics of LED lights?It's a point light source, very bright.So if you want to turn this light into a plane, or if you want to increase its illumination range, it needs to diffuse to do that.

When choosing materials for classroom lamps and lanterns, we hope to use materials with good optical properties, anti-glare materials, long-life materials, and materials in line with safety and environmental protection.This is a comparison of materials made by us in four processes: anti-glare effect, anti-glare efficiency of UGR, material life, safety, installation and use cost of products, thank you!(Reprint)
