Embodiment Construction

[0037] Such as Figure 5 Shown is the light path diagram of the embodiment of the LED anti-glare lamp of the present invention. The LED anti-glare lamp of the present invention comprises: LED light source 100, concave lens 200 and anti-glare transparent member 300; 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, and is used for flooding the light after the concave lens 200 is flooded for the second time, thereby converting the point light source into surface light source.

[0038] Such as Figure 6 Shown is a schematic structural diagram of the LED light source 100 . 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 emitting light, and a primary lens 102 . Wherein, the primary lens 102 is a spherical lens. figure 1 , figure 2 and image 3 The light distrib...

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 the LED 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 LED lighting fixtures, more specifically, to an LED anti-glare lamp. Background technique [0002] With the advancement of technology, high-power SMD light emitting diodes (light emitting diodes, LEDs) are not only used in flashlights, headlights, floodlights and other products, but also more and more used in indoor floodlights. lighting fixtures. [0003] At present, the surface brightness of ordinary fluorescent tubes is about 7000-8000cd / m2, which can meet the glare requirements of the human eye in an indoor environment, that is, the human eye 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 the high luminous flux (above 60lm / W) of the LED lamp, the surface brightness of the LED is very high, and the maximum brightness generally exceeds 300,000cd / m2. figure 1 Shown is the light distribution curve of existing LED light sources such as CREE ...
