The general lighting design is to calculate the illumination of the space in the night state assuming that the window has no light entering, thereby determining the configuration of the lighting device. A good lighting environment must not only have a sufficient source of illumination, but also distribute uniform illumination and avoid glare as much as possible.
Figure 1: The glare effect of the light source
Glare is a visual phenomenon that is caused by an unsuitable brightness distribution or a range of brightness, or an extreme brightness contrast, which causes an uncomfortable feeling or reduces the ability to observe details or targets. At present, there is a serious glare of LEDs on the market. If the human eye is exposed to glare for a long time, it will feel like eyes, dizziness and discomfort. Working under such conditions can cause boredom, irritability and fatigue, which have a great impact on people's production and life. No glare lamps were invented to solve the above problems.
There are usually two types of luminaire glare: direct glare and reflected glare. The glare of LED lights usually refers to reflected glare. As an LED luminaire manufacturer, if you choose a bumpy polycrystalline reflective optical lens, it is completely achievable to combine the optimized optical application design of the frosted tempered glass.
Figure 2: Principle of light output from conventional lenses and reflectors
The above is the light output principle of the lens and reflector commonly used in LED lamps on the market. It is not difficult to imagine that when the light converges in the range of the focus of the eye, the convergence of the light causes the human eye to increase the light intensity when receiving the light, resulting in glare reaction of the eye discomfort; there is also a case where the convergence point of the light is much smaller than the visual focus. The coke is that the light is too weak, resulting in a very weak light intensity, which also makes the human eye uncomfortable due to fatigue, and is one of the factors that cause glare reaction.
The core of solving the above glare problem is how to make the light output evenly in the process of output. Shenzhen Yineng Optoelectronics Technology Co., Ltd. independently invented (patent number ZL201220157321.9) polycrystalline pure parabolic micro-ribbed glare-free technology, using parabolic surface The principle of reflecting uniform parallel light has developed a pure parabolic reflector. The quality of the lighting is different, achieving true glare-free lighting, no light pollution, and high uniformity.

Polycrystalline pure parabolic micro-ribbed glare-free technology, using LED light and physical reflection, make LED lamps without glare, no ghosting, avoiding the brightness of the light source is too glaring, causing disgusting, uncomfortable and other visual discomfort. Applicable to high-end offices, conference rooms, conference halls, reception areas, etc. where lighting visual comfort is high.
