Description

Anti-dazzle cover and lamp

Technical Field

The utility model relates to the field of lamps, in particular to an anti-dazzle cover and a lamp.

Background

Light rays emitted by light sources of existing down lamps, spot lamps, wall washing lamps and the like are directly emitted outwards, and as the light rays emitted by the light sources are at a certain angle, such as 30 degrees, 45 degrees or 60 degrees, one part of the light rays emitted by the light sources are emitted to a light receiving body (such as a wall body), the other part of the light rays are not emitted to the light receiving body, such as the part of the light rays directly enter human eyes, and the light intensity is high, so that an obvious dazzling glare phenomenon can be caused. Therefore, an anti-dazzle cover is generally arranged on the lamp, and is used for partially shielding light rays emitted laterally from a light source, so that the light rays are prevented from directly entering human eyes.

Referring to chinese patent of patent No. CN213019246U, in the prior art, the antiglare shield includes a shield body, a light-transmitting hole site axially penetrating the shield body is provided on the shield body, an outward flange for supporting the antiglare shield is provided outside an upper hole edge of the light-transmitting hole site, and since the outward flange only plays a role in supporting the antiglare shield, the outward flange is narrow, which causes the following defects:

(1) under the condition of the same outer diameter (the maximum outer diameter of the anti-dazzle cover is the same), the upper opening of the light-transmitting hole site is large, so that the light spot formed by the irradiation of the lamp is large, and in some application scenes, the large light spot is not needed, so that the decorative effect of the light spot is improved, and the anti-dazzle cover does not meet the use requirement;

(2) the model belongs to the conventional model, and the exposed surface of the anti-dazzle cover (the top surface of the anti-dazzle cover) is common, so that the front surface (the light-emitting surface) of the lamp is common in model, and the product competitiveness is small;

(3) if the outward flange is directly made wide, the outward flange is planar, the appearance aesthetic property of the anti-dazzle cover is not friendly, the anti-dazzle cover is made of metal or a coating material, the surface mirror surface degree is very high, and the planar structure of the outward flange can also form dazzle after reflecting light reflected back to the plane by the light receiver for the second time.

For this reason, improvements and optimizations are necessary to existing antiglare shields and luminaires.
