Problems solved by technology

For this reason, the existing space lighting mainly uses reflectors or shutters to limit the illumination beam to the direction that is not expected to be illuminated, or to increase the shading angle of the lamp (that is, the angle between the illumination beam and the horizontal line)
Another method is to use diffuser elements to cover the bright beam, but it will affect the light effect or the anti-glare effect is not good

Embodiment Construction

[0039] Specific embodiments of the present invention will be described in further detail below based on the accompanying drawings. It should be understood that the description of the embodiments of the present invention here is not intended to limit the protection scope of the present invention.

[0040] Such as figure 1 As shown, the anti-glare reflective cup 1000 of this embodiment includes a reflective side wall 100, and the reflective side wall 100 surrounds a reflective cavity 101. The reflective cavity 101 is roughly tapered, the large end is the light outlet 200, and the small end is A light source placement place 300 is provided nearby. The above structure is consistent with the reflector cup in the prior art. The reflector cup refers to a reflector used for point light sources and requires spotlight lighting. It is usually cup-shaped, commonly known as a reflector cup. 200. The substantially tapered shape here refers to the shape formed by the gradual change from t...

Abstract

The invention discloses an anti-dazzle reflection cup. The anti-dazzle reflection cup comprises reflection side walls, the reflection side walls form a reflection cavity in a surrounding manner, the reflection cavity is approximately conical, the large end of the reflection cavity is a light outlet, a light source containing position is arranged near the small end of the reflection cavity, a straight line which passes through the light source containing position and is perpendicular to the plane where the light outlet is located is defined as an optical axis, and in any plane passing through the optical axis, a light source placed at the light source containing position comprises a first light beam directly emitted from the light outlet and a second light beam emitted from the light outletafter being reflected by the reflection side walls; and on the same side of the optical axis, the maximum included angle formed by intersection of the first light beam and the optical axis is the maximum direct emergence angle, the maximum included angle formed by intersection of the light emitted from the light outlet after the second light beam is reflected by the reflection side walls and theoptical axis is the maximum reflection emergence angle, and the maximum reflection emergence angle is smaller than or equal to the maximum direct emergence angle. By means of the anti-dazzle reflection cup and the lamp with the reflection cup, excellent lighting experience is brought, and the problems of dazzling and heavy glare are solved.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an anti-glare reflective cup and a lamp with the reflective cup. Background technique [0002] In the context of energy saving and environmental protection, LED lamps are more and more used in the fields of home and commercial lighting because of their high light extraction efficiency and good light-gathering performance. [0003] In the application of interior lighting design in homes, offices or commercial places, visual comfort is extremely important. To achieve this, choose products that reduce both direct and reflected glare. Proper placement of luminaires and the use of optical components that can reduce direct glare and reflected glare can reduce the impact of glare on people or damage to human eyes. [0004] To reduce glare, you should provide as uniform a direct beam as possible, and reduce lateral beams parallel to the horizontal plane of the illuminated space. For ...
