Embodiment Construction

[0037] Such as Figure 5 Shown is an optical path diagram of an embodiment of the LED anti-glare lamp of the present invention. The LED anti-glare lamp of the present invention includes: an LED light source 100, a concave lens 200, and an anti-glare transparent member 300; wherein, the LED light source 100 is located in the center of the LED anti-glare lamp, and the concave lens 200 covers the LED light source 100 for matching The light emitted by the LED light source 100 is flooded for the first time, and the anti-glare transparent member 300 covers the concave lens 200 for the second flooding of the light after the concave lens 200 is flooded, thereby converting a point light source into Surface light source.

[0038] Such as Image 6 As shown, the structure diagram of the LED light source 100 is shown. The LED light source 100 used in the embodiment of the present invention is a CREE XR-E 3W LED. The LED light source 100 has a center 101 of the LED light source 100 that emit...

Abstract

The invention relates to an LED (Light-Emitting Diode) anti-dazzle lamp comprising an LED light source (100), a concave lens (200) and an anti-dazzle transparent part (300), wherein the LED light source is provided with a primary lens (102), the concave lens (200) envelopes the primary lens (102) of the LED light source (100) and is used for carrying out primary flood on the emergent light of theLED light source (100), and the anti-dazzle transparent part (300) envelopes the concave lens (200) and is provided with annular sawteeth and used for carrying out secondary flood on the flooded light rays of the concave lens (200). The LED anti-dazzle lamp disclosed by the invention can effectively reduce the surface brightness, realize relatively uniform illumination, and meet the requirement on the human eye adaptation to brightness under an indoor environment.

Description

Technical field [0001] The invention relates to an LED lighting lamp, and more specifically, to an LED anti-glare lamp. Background technique [0002] With the advancement of technology, high-power SMD light emitting diodes (LEDs) are not only used in flashlights, headlights, floodlights and other products, but also more and more are used in indoor floodlights. Lighting fixtures. [0003] At present, the surface brightness of ordinary fluorescent tubes is about 7000-8000 cd / m2, which can meet the glare requirements of human eyes in an indoor environment, that is, human eyes can adapt to such a range of brightness. However, due to the small size of the light source (generally less than 6mm in diameter) and high luminous flux (above 60lm / W), the LED surface brightness is very high, and the maximum brightness generally exceeds 300,000 cd / m2. figure 1 Shown is the light distribution curve of an existing LED light source such as CREE XR-E 3WLED, figure 2 Shown as its light spot effect ...
