Multi-small-hole high-density light-emitting device and light guide piece

Abstract

The invention discloses a multi-small-hole high-density light-emitting device and a light guide piece, and the light-emitting device comprises a panel, a lamp panel fixedly installed on the inner side surface of the panel, lamp beads fixedly arranged on the lamp panel, the light guide piece fixedly arranged on the lamp panel and used for covering the lamp beads, and a light-emitting column arranged on the light guide piece, and the panel is provided with a light-emitting hole through which the light-emitting column can pass. When the multi-small-hole high-density light-emitting device is used, the light guide part is arranged on the lamp beads of the lamp panel in a covering mode, then the light-emitting columns on the light guide part are aligned with the light-emitting holes in the panel to be inserted, light emitted by the lamp beads is continuously reflected to enable the light guide part and the light-emitting columns to become light sources, and then the light-emitting columns penetrate through the light-emitting holes to emit light outwards. The technical scheme can be used for small hole light transmission of a high-end product, and when the number of small light-emitting holes of the product is too large and the position of a lamp distribution area is too small, the size limitation of the lamp distribution area can be broken through through bridging of the light guide piece in the structure.

Description

Technical Field

[0001] The present invention relates to a light emitting device, and more particularly to a light emitting device with multiple small holes and high density and a light guide. Background Art

[0002] In the prior art, in order to achieve a better decorative effect, some electronic devices, home appliances or household equipment are usually provided with a large number of small light-emitting holes. Most existing decorative light panels emit light directly through small holes through lamp beads, but since the volume of existing lamp beads is much larger than the high-density small holes on the panel, the light-emitting effect of the lamp beads and the lamp holes is greatly affected, and it is difficult to arrange the lamp beads on the light panel, resulting in limited design of the position of the high-density light-emitting small holes on the panel. Summary of the invention

[0003] In view of the above-mentioned defects of the prior art, the present invention provides a multi-hole high-density light-emitting device and a light-guiding member.

[0004] The technical solution adopted by the present invention to solve its technical problem is: constructing a multi-hole high-density light-emitting device, which includes a panel, a lamp board fixedly installed on the inner side of the panel, lamp beads fixed on the lamp board, a light guide fixed on the lamp board and used to cover the lamp beads, and a light-emitting column arranged on the light guide, and the panel is provided with a light-emitting hole for the light-emitting column to pass through.

[0005] In the multi-hole high-density light-emitting device of the present invention, the bottom surface of the light guide is provided with a lamp groove for the lamp bead to be embedded and accommodated, and the light-emitting column is arranged on an end of the light guide away from the lamp groove.

[0006] In the multi-hole high-density light-emitting device of the present invention, a hot post is provided on the bottom surface of the light guide, and a fixing hole for the hot post to be inserted and connected is provided on the lamp panel.

[0007] In the multi-hole high-density light-emitting device described in the present invention, the light-guiding member is provided with an extension member extending outward, and the light-emitting column is fixed on the extension member.

[0008] In the multi-hole high-density light-emitting device described in the present invention, the light-guiding member, the extending member and the light-emitting column are integrally formed of a light-transmitting material.

[0009] In the multi-hole high-density light-emitting device described in the present invention, the light-transmitting material is made of transparent PC material with a light-scattering agent added thereto.

[0010] Another technical solution adopted by the present invention to solve its technical problem is: constructing a light guide, which includes a light-transmitting body, a lamp groove arranged on the bottom surface of the light-transmitting body for lamp beads to be embedded and accommodated, and a light-emitting column arranged on the light-transmitting body away from the lamp groove.

[0011] In the light guide member of the present invention, the bottom surface of the light-transmitting body is provided with a hot post for fixing the light-transmitting body.

[0012] In the light guide member described in the present invention, the light guide member further comprises an extension member extending outward from the light-transmitting body, and the light-emitting column is fixed on the extension member.

[0013] In the light guide member described in the present invention, the light-transmitting body, the extension member and the light-emitting column are integrally formed of a light-transmitting material, and the light-transmitting material is made of a transparent PC material with a light-scattering agent added thereto.

[0014] The implementation of the multi-hole high-density light-emitting device and light guide of the present invention has the following beneficial effects: when using the multi-hole high-density light-emitting device of the present invention, the light guide cover is set on the lamp beads of the lamp board, and then the light-emitting column on the light guide is aligned with the light-emitting hole on the panel and inserted. The light emitted by the lamp beads is continuously reflected to make the light guide and the light-emitting column a light source, and then the light is emitted outward through the light-emitting hole by relying on the light-emitting column. By implementing the technical scheme of the present invention, the lamp board and the lamp beads can be appropriately away from the corresponding light-emitting holes (to prevent the lamp beads and the lamp board from interfering with each other) according to the number and distance of the light-transmitting holes of different products. It can be used for high-end products with small holes for light transmission. When the product has too many small light-emitting holes and the area for lighting is too small, it can be bridged by the light guide in this structure to break through the size limit of the lighting area. At the same time, the overall appearance of the product can have uniform light holes, soft and uniform light sources, and high-end light transmission effects. BRIEF DESCRIPTION OF THE DRAWINGS
