Lamp component and loudspeaker box

Abstract

The invention discloses a lamp component and a loudspeaker box. The lamp component comprises a PCB (Printed Circuit Board), LED (Light Emitting Diode) lamps and a light guide ring; the PCB is arrangedabove the light guide ring; the LED lamp is arranged on the face, facing the light guide ring, of the PCB; light emergent holes are formed in the PCB; the light guide ring is a hollow ring; the lightguide ring comprises a first light emergent face, a second light emergent face, an incident face, a reflecting face and a bottom face which are connected in sequence; the first light emergent face islocated on the outer circumference of the light guide ring; the second light emergent face is arranged oppositely to the bottom face and faces the PCB; the incident face and the reflecting face are located on the inner circumference of the light guide ring; LED lamps are opposite to the incident face; and light rays, incident upon the light guide ring, of the LED lamps can exit from the first light emergent face and the second light emergent face. According to the lamp component and the loudspeaker box disclosed by the invention, the LED lamps are arranged on the PCB in an inversion manner; the LED lamps no longer need to be arranged at different positions, and different PCBs are no longer needed to control the LED lamps at different positions to emit light, so that the number of the PCBsand the number of the LED lamps can be reduced.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a lamp assembly and a sound box. Background technique [0002] At present, in order to realize the richness of functions of speaker products, lighting components are provided in the speakers to realize the effect of lights accompanied by sound produced by the speaker products. Lighting components usually include PCB boards, LED lights, and light guide rings. However, the light guide space in the speaker product is limited, resulting in a short light mixing distance between the LED lamp and the light guide ring, which is not conducive to the mixing of light. In order to make the light emitted from the light guide ring uniform, it is usually necessary to increase the number of LEDs, which increases the cost. [0003] In view of the above drawbacks, it is necessary to provide a new lamp assembly. Contents of the invention [0004] The main purpose of the present invention i...
