Problems solved by technology

[0004] At present, for the anti-glare of direct-projection LED light sources, frosted transparent parts are mainly used, or transparent parts are made into stripes, etc. This method can achieve a certain anti-glare effect, but the anti-glare effect is not ideal, and the light transmission The efficiency is low, resulting in low lighting efficiency of lamps

Embodiment Construction

[0028] The preferred embodiments of the present invention will be described in detail below with reference to the drawings.

[0029] The light source suitable for the anti-glare LED lighting fixture of the present invention is a single direct-projection light-emitting LED light source 10, and its illuminance schematic diagram is as follows figure 1 shown.

[0030] The anti-glare LED lighting fixture of the embodiment of the present invention is mainly composed of an LED light source 10, a beam splitter 30, and a reflector 20 capable of reflecting light, such as image 3 shown. The LED light source 10 is fixed on the bottom of the reflector 20 and includes an LED lamp and an LED chip for driving the LED lamp. A beam splitter 30 is arranged directly in front of the light emitting surface of the LED light source 10 . The beam splitter 30 adopted can be slightly larger than the LED chip, and its structure is as follows: Figure 4 shown. The optical path principle of the beam ...

Abstract

The invention relates to an anti-dazzle LED illuminating lamp and a reflection structure thereof. The LED illuminating lamp comprises a reflector and a LED light source which is positioned at the bottom of the reflector; wherein, a beam splitter which can divide a light beam emitted from the LED light source into a transmitted light beam and a reflected light beam between which the light intensity ratio is predetermined; the reflected light is reflected again by the reflector to illuminate together with the transmitted light. According to the invention, the beam splitter is employed to decrease the center intensity of the light source of the lamp, then the reflector is employed to distribute light beams, so that not only can the objective of dazzle prevention be realized to allow people to feel comfortable without being dazzled when they stare directly at the LED illuminating lamp, but also the illumination efficiency of the lamp can be ensured, meanwhile, the integral lamp can have a compact structure.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to an anti-glare LED lighting fixture and a reflection structure thereof. Background technique [0002] While the current LED power is getting larger and larger, the size of the LED chip is developing in a smaller direction, so the peak brightness of the LED light source is very high. The illuminance is basically greater than 1 million lux. When the human eye looks directly at the LED light source, it will cause discomfort and serious glare problems. [0003] At present, there are various LED anti-glare lighting products, some of which adopt the method of uniform light plate for anti-glare. It needs to use the traditional light guide plate and light uniform plate at the same time to realize the surface light source with uniform brightness. This solution is suitable for The side-emitting light source is not suitable for the anti-glare of the direct-projection LED light source. The side-emitting...
