Uniform light guide structure of LED light and intelligent sound box

Abstract

The invention relates to a uniform light guide structure of LED light and an intelligent sound box. The light guide structure comprises a light guide assembly, a light guide member and a plurality of side light emitting LEDs; the light guide assembly comprises a first reflection layer, a light guide layer, a second reflection layer and a shielding layer arranged from bottom to top; a plurality of first evasion holes are formed in the first reflection layer at intervals, a plurality of second evasion holes are formed in the light guide layer, and a plurality of third evasion holes are formed in the second reflection layer; the first evasion holes, the second evasion holes, the third evasion holes and the shielding layer form a chamber for accommodating the side light emitting LEDs; an upper surface of the first reflection layer is a reflection surface, and the lower surface of the first reflection layer is an opaque surface; necks are disturbed on the upper surface of the light guide layer; the lower surface of the second reflection layer is a reflection surface, and the upper surface of the second reflection layer is an opaque surface; and the lower surface of the shielding layer is a reflection surface, and the upper surface of the shielding layer is an opaque surface. While uniform light guide of LED light is realized, the size of the intelligent sound box does not need to be additionally increased.

Description

technical field [0001] The invention belongs to the technical field of light guide for smart speakers, and in particular relates to a uniform light guide structure for LED light and a smart speaker. Background technique [0002] With the user's requirements for quality of life and the development of intelligent technology, smart home appliances (such as smart speakers) are rapidly entering daily life. One of the highlights of the smart speaker is the light, which is emitted by the LED components inside the speaker and can flash with the rhythm of the music, so that users can enjoy music while bringing more fun. The light in the smart speaker in the prior art is emitted by the LED component, and then transmitted to the long strip or circular light guide, and the light is scattered outward by the light guide, because the light guide plate will have some Loss, causing the brightness near the LED lamp is relatively large, while the position between adjacent LED lamps is relativ...

AI Technical Summary

Problems solved by technology

The light in the smart speaker in the prior art is emitted by the LED component, and then transmitted to the long strip or circular light guide, and the light is scattered outward by the light guide, because the light guide plate will have some Loss, causing the brightness near the LED lamp is relatively large, while the position between adjacent LED lamps is relatively dark

In response to this problem, structural parts for reflection are designed in the prior art, but these structural parts need to occupy a large space, increase the volume of the speaker product, and make the product heavy and inconvenient to carry
