Whole-circle light assembly and key module with whole-circle light effect

Abstract

The invention discloses a whole-circle light assembly. An LED lamp set comprises a lamp holder and a plurality of LED lamp beads, the lamp holder is of an annular structure, a light guide piece is located above the lamp holder, the LED lamp beads are installed on the lamp holder and annularly distributed around the light guide piece, and a containing groove used for containing the LED lamp beads is formed in the outer wall of the light guide piece. The whole circle of light assembly is designed in an optimized mode. The lateral light-emitting LED lamp set is adopted, light is guided out from the side face through the light guide piece, it is avoided that other module flat cables of the key block the light, meanwhile, the LED lamps are evenly distributed in a surrounding mode, the problem of bright spots generated due to the fact that the distance between the lamps and the aperture is too short is solved, and therefore the aperture with even brightness is formed around the key. The invention further discloses a key module with the whole-circle light effect.

Description

technical field [0001] The invention relates to the technical field of electronic equipment keys, in particular to a full-circle lighting component and a key module with full-circle lighting effects. Background technique [0002] At present, the main design scheme of the light-emitting aperture of the power button is to use LED lights to illuminate the button and the light guide lens vertically. The button and the light guide lens use light-transmitting materials to guide the light out, so that the appearance of the Lens produces a luminous aperture. The light emitted by the light guide Lens cannot be uniform, and the aperture on the outside will have different light and dark areas. Especially when setting up the fingerprint module, the wiring of the fingerprint module will block the light, so that the light in the wiring area of ​​the fingerprint module cannot be exported through the Lens. Contents of the invention [0003] In order to solve the technical problems in the...
