Abstract

The invention discloses an anti-dazzling narrow-beam LED lamp. The anti-dazzling narrow-beam LED lamp comprises an optical assembly and a light source. The optical assembly comprises a lens support with the surface provided with a light absorbing part, and the light absorbing part is a black or deep color coating and is used for absorbing light rays. At least a first installing part and a second installing part exist in the lens support. A light restraining plate is arranged between the first installing part and the second installing part, and a light stop part is arranged on the single side of the light restraining plate. The light absorbing part is preferably a black or deep color coating and is used for absorbing unnecessary stray light, and accordingly, the effect of dazzling preventing is achieved. A light emitting angle and the light stop part are arranged on the single side of the light restraining plate of the lens support, accordingly, the light emergent direction and angle are changed and limited, the narrow beam is formed, higher wall faces can be brightened, and the purposes of wall washing and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of special optical design of LED lamps, in particular to an LED lamp with anti-glare and narrow beam. Background technique [0002] As a new type of green lighting source, LED is more and more accepted and promoted by all walks of life due to its many advantages such as energy saving, high luminous efficiency, rich colors, and long life. However, people have higher and higher requirements for the use of LED lamps. For example, lamps need to have anti-glare function, and the demand angle is becoming more and more strict. Although a sunshade can be added to the outer surface of the lamp, it destroys the appearance of the LED lamp, and at the same time, some installation environments will meet the requirements of materials. The optical design of the LED lamp described in the present invention meets the strict optical requirements of a narrow angle, and has anti-glare function without changing the external stru...
