Annular light guide strip and light source module

Abstract

The invention provides an annular light guide strip and a light source module, the annular light guide strip comprises an annular body part and a light-in part, the annular body part is provided with a light emitting surface and a bottom surface, the light emitting surface and the bottom surface are two opposite annular surfaces of the annular body part, the annular body part is provided with a plurality of light guide structures, and the plurality of light guide structures are arranged on the light emitting surface; and the light-in part is arranged on the annular body part and protrudes from the side edge of theannular body part, the light-in part is provided with a light-in surface, and the plane where the light-in surface is located intersects with the plane where the light-out surface is located. The light incident direction corresponds to the extension direction of the annular light guide strip, so that cost optimization and light emitting uniformity can be achieved under the condition that the number of light sources is reduced. In addition, when the light sources of the light source module are used up and need to be maintained, due to the fact that the number of the used light sources is small, the purpose of saving time in replacing can be achieved, and meanwhile the maintenance cost is low.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an annular light guide strip and a light source module. Background technique [0002] Due to the appearance of today's products, in order to seek innovation and beauty, ring lights are becoming more and more popular. In order to achieve ring lighting, one of the existing light-emitting mechanisms is to use multiple light-emitting diode (LED) light sources to emit light forward, or to use flexible light strips to bend into special shapes. [0003] However, multiple LED light sources are used to emit light in the forward direction. In order to avoid uneven brightness and darkness of the light source on the appearance, multiple LED light sources need to be evenly arranged along a ring shape, which makes the cost relatively high. The use of flexible light strips in the circular appearance will produce relatively dark areas in the connected contact areas, which cannot meet the user'...

[0003] However, multiple LED light sources are used to emit light in the forward direction. In order to avoid uneven brightness and darkness on the appearance, multiple LED light sources need to be evenly arranged along the ring, which makes the cost relatively high.

The use of flexible light strips in the circular appearance will produce relatively dark areas in the connected contact areas, which cannot meet the user's needs for product appearance in terms of today's increasingly refined appearance requirements.
