The invention relates to the technical field of light guiding of lamps, particularly to an annular halo lamp. The annular halo lamp comprises a light guide plate and a shading device, wherein the light guide plate comprises an upper surface, a lower surface and a side surface; the upper surface and the lower surface cover the shading device; a plurality of accommodating cavities used for accommodating light sources are formed in the lower surface; the side surface comprises an annular surface which emits light in the upper surface direction; the light guide plate adopts a transparent material; and white reflective layers are arranged on the outer surfaces, except from the annular surface and the inner surfaces of the accommodating cavities, of the light guide plate. According to the annular halo lamp, the lamp does not need to be matched with a light diffusion lampshade, so that a lot of light loss is avoided, and the number of the light sources is decreased; and the integral occupied space is small, the structure is simple, the luminescence is uniform, and the manufacturing cost of the annular halo lamp is reduced.
Description
technical field [0001] The invention relates to the technical field of lamp light guide, in particular to an annular halo lamp. Background technique [0002] The ring halo lamp is a kind of car lamp that can emit a special-shaped ring halo effect, which is applied to the luminous sign lights of the car exterior parts and the decorative lights of the car interior parts. [0003] The existing automotive annular halo lamps deal with the annular halo by densely arranging light-emitting diodes behind the light-emitting surface, and then cooperate with the light-diffusing lampshade to achieve the luminous effect of uniform halo. The disadvantage of such a structure is that it needs to cooperate with the light diffusion lampshade, resulting in a large light loss. In order to meet the brightness requirements of the ring-shaped lamp, a large number of light-emitting diodes are required, which takes up a lot of space and increases the ring-shaped halo lamp. manufacturing cost.
