Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to an anti-glare downlight. Background Art

[0002] Downlights have become a popular choice for home and commercial lighting design due to their ease of use, durability, and space-saving embedded installation. However, in actual use, downlights may produce glare for a variety of reasons, which not only affects the lighting effect, but may also have adverse effects on the user's visual experience and health.

[0003] First of all, the design characteristics of downlights are one of the main reasons for glare. Downlights usually adopt a focusing design, which converges the light emitted by the light source through a reflector or lens to form a concentrated beam. However, this design may cause the light to be too concentrated in some cases, forming a strong spot or halo, thus causing glare. In particular, if the design between the light source and the reflector is inappropriate, the light may be reflected multiple times during the reflection process, exacerbating the glare phenomenon.

[0004] Secondly, the installation position and angle of the downlight are also key factors that cause glare. If the downlight is installed too close to the wall or the ground, the light it emits may directly enter the user's eyes after reflection, causing glare. In addition, if the downlight is installed at an inappropriate angle, causing the light to directly hit the user's eyes or the reflective surface, glare will also occur.

[0005] Furthermore, the light source and lamp materials used in downlights may also affect the occurrence of glare. Some light sources with high brightness or high color temperature are more dazzling and easily cause glare. Some low-quality lamp materials, such as uneven reflector surfaces and poor light transmittance, may also cause light to scatter or refract during propagation, forming glare. Utility Model Content

[0006] In view of the above-mentioned deficiencies of current downlights, the utility model provides an anti-glare downlight, which can achieve the effect of reducing the glare phenomenon of the downlight.

[0007] In order to achieve the above object, the embodiment of the utility model adopts the following technical solution:

[0008] An anti-glare downlight comprises a lighting module, a lamp housing and a hook assembly, wherein the lighting module is arranged in the lamp housing, and the lamp housing comprises a mounting shell, an anti-glare cover and a mounting platform; the lighting module is fixed in the mounting shell, and the anti-glare cover is arranged between the mounting shell and the mounting platform, and a plurality of anti-glare steps are arranged on the inner side of the anti-glare cover; the plurality of anti-glare steps are connected in sequence; the anti-glare steps comprise a connecting edge, a rounded transition portion and a diffusion edge; the connecting edge is perpendicular to the central axis of the lamp housing, and the angle between the diffusion edge and the central axis of the lamp housing is between 9° and 11°.

[0009] According to one aspect of the present invention, the number of the anti-glare steps is seventeen.

[0010] According to one aspect of the utility model, the angle between the diffusion edge and the central axis of the lamp housing is 10°.

[0011] According to one aspect of the utility model, a reinforcing ring is provided at the connection between the mounting shell and the anti-glare cover.

[0012] According to one aspect of the utility model, a hook fixing screw hole is provided on the installation shell; the hook assembly is fixedly connected to the installation shell through the hook fixing screw hole.

[0026] Among them, a plurality of step structures connected end to end in sequence are arranged inside the anti-glare cover 12, which can increase the internal reflection area without changing the opening diameter and general shape of the lamp housing 1, effectively avoiding excessive concentration of light from the light source, thereby avoiding glare; the rounded transition portion 123 between the connecting edge 122 and the diffusion edge 124 can also increase the diffuse reflection area and optimize the anti-glare effect;

[0027] In practical applications, the number of the anti-glare steps 121 is seventeen, which can ensure that the size of each anti-glare step 121 is appropriate;

[0028] Due to the characteristics of the step structure, the angle between the diffusion edge 124 and the central axis of the lamp housing 1 will be smaller than the opening angle of the anti-glare cover 12, making it easier for the light emitted by the light source to be reflected, thereby avoiding excessive concentration of light in the central part of the downlight, thereby achieving the effect of reducing glare. In practical applications, the angle between the diffusion edge 124 and the central axis of the lamp housing 1 takes an optimal value of 10°, which can make the light of the downlight light source be reflected at a suitable angle, avoid excessive concentration of light, and ensure the anti-glare effect.
