Problems solved by technology
[0004] Compared with traditional light sources, LED light sources have the characteristics of high efficiency, safety, energy saving, environmental protection, long life, fast response speed, and high color rendering index. Especially in terms of volume, LED lamps are smaller, but the accompanying glare problem LED lamps face certain challenges. The traditional methods of dealing with glare include hiding the light source deeply, adding anti-glare rings and grilles, etc., but all of these are at the cost of reducing the efficiency of the lamps, which is not conducive to the consideration of energy saving and Failure to make better use of the characteristics of LED light sources

Embodiment Construction
[0024] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0025] see figure 1 and Figure 1a , LED non-planar optical mask, composed of multiple non-planar mixed light anti-glare optical unit structures with the same or different structures, the optical unit structure is a semi-closed shell, and the opening part of the shell corresponds to the installation hole of the LED lamp bit. The optical unit structure is a non-planar optical unit structure, which has the function of mixing light and dazzling. Specifically, the outer ring optical unit structure 2 of the mask 1 is dome-shaped, and the inner ring optical unit structure 3 of the outer ring optical unit structure 2 is a relatively short dome-shaped structure. Eight optical unit structures 2 are closely arranged on the outer ring, and the inner ring...

The invention discloses a novel LED (light emitting diode) non-plane type optical mask which is applied to lamps with an LED light source. The invention is characterized in that the optical mask structure is composed of one or multiple non-plane optical unit structures, wherein each optical unit structure is a semiclosed shell structure, the opening part of each optical unit structure corresponds to an LED mounting hole site; the optical mask structure also can be composed of one or multiple optical unit structures; the material of the optical mask structure is a transparent diffusion material or a transparent material having the surface subjected to treatment (such as atomization). By adopting the non-plane type optical mask structure, light distribution of the LED space of the LED lamp can be effectively improved, a hybrid optical effect can be reached and glaring interference of the LED lamp can be reduced.
Description
technical field [0001] The invention relates to a novel LED non-planar optical mask structure, which is used in conjunction with an LED light source to improve the spatial distribution of a light field, and effectively controls surface glare for LED lamps. Background technique [0002] With the vigorous development of semiconductor lighting, the power and luminous efficiency of LED light sources continue to increase, while the size of LED chips is increasingly miniaturized, which also causes the peak brightness of LED light sources to continue to increase. Currently, high-power white LEDs on the market (Power greater than 1W) The peak brightness of the light source is basically 1 million Cd / m2. When the human eye directly looks at the LED light source, it will cause discomfort, serious glare problems, and serious damage to the human eye. [0003] In addition, the light emitting surface of the LED light source is a plane, and its luminous characteristics are Lambertian distri...
