Abstract

The utility model discloses an anti-static LED aluminium substrate, comprising, from the top to the bottom, a first insulating layer (1), a conducting layer (2), a second insulating layer (3) and a metal substrate (4), wherein the metal substrate (4) is provided with a plurality of conductive projections (5), the conductive projections (5) penetrate the first insulating layer (1), the conductive layer (2) and the second insulating layer (3), the conductive layer (2) near the conductive projections (5) is spaced so as to guarantee direct combination between the first insulating layer (1) and the second insulating layer (2). With such as structure, the conductive projections can conduct static accumulated on the insulating layers to the metal substrate, thereby effectively preventing static harm.

Description

Antistatic LED aluminium base

Technical field

The utility model relates to the LED field of light fittings, particularly a kind of antistatic LED aluminium base.

Background technology

LED lamp pearl has advantages such as luminous efficiency height, volume are little, in light weight, environmental protection, and how the characteristic according to led light source is suitable for design, and more new demand is arranged; Because the brightness of single LED lamp pearl is limited, for the light intensity that makes generation reaches lighting requirement, need be in light fixture integrated LED lamp pearl in a large number; The LED lamp integument of these One's name is legions is integrated in and forms the emitting led module of polylith on the some circuit boards, these LED modules is fixed in the lamp housing, to constitute the light source of led lamp again; The general aluminium base with thermal conductive resin that adopts of used circuit board serves as, and existing aluminium base adopts hierarchical structure, is followed successively by first insulating barrier, conductive layer, the mat woven of fine bamboo strips two insulating barriers and substrate from top to bottom; LED lamp pearl is connected through pin and conductive layer, and still, there is static hidden danger in the aluminium base of this structure; Very easily produce static on first surface of insulating layer; Dredge approach owing to lack static, when buildup of static electricity to a certain degree being generation instantaneous discharge phenomenon; Cause great electric current transient flow through light-emitting diode, cause the damage of light-emitting diode.

The utility model content

The purpose of the utility model is to provide a kind of antistatic LED aluminium base.

The goal of the invention of the utility model realizes through following technical scheme: a kind of antistatic LED aluminium base; Be followed successively by first insulating barrier, conductive layer, the mat woven of fine bamboo strips two insulating barriers and metal substrate from top to bottom; Be formed with some conductive prominences on the said metal substrate; Conductive prominence penetrates first insulating barrier, conductive layer and the mat woven of fine bamboo strips two insulating barriers, and conductive prominence near conductive layer leave a blank so that first insulating barrier and second insulating barrier directly combine.

Adopt the LED aluminium base of this structure, set conductive prominence can effectively prevent electrostatic hazard with conducting on the metal substrate at the static of piling up on the insulating barrier.

Below in conjunction with accompanying drawing and embodiment the utility model is further set forth, the protection range of the utility model includes but are not limited to accompanying drawing and the disclosed content of embodiment.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further to set forth.

As shown in Figure 1; This LED aluminium base adopts hierarchy; Be followed successively by first insulating barrier 1, conductive layer 2, the mat woven of fine bamboo strips two insulating barriers 3 and metal substrate 4 from top to bottom, be formed with some conductive prominences 5 on the metal substrate 4, conductive prominence 5 penetrates first insulating barrier 1, conductive layer 2 and the mat woven of fine bamboo strips two insulating barriers 3; And near the conductive layer 2 the conductive prominence 5 is left a blank, so that first insulating barrier 1 and second insulating barrier 2 are directly fitted.

Claims

1. antistatic LED aluminium base; Be followed successively by first insulating barrier (1), conductive layer (2), the mat woven of fine bamboo strips two insulating barriers (3) and metal substrate (4) from top to bottom; It is characterized in that: be formed with some conductive prominences (5) on the said metal substrate (4); Conductive prominence (5) penetrates first insulating barrier (1), conductive layer (2) and the mat woven of fine bamboo strips two insulating barriers (3), and conductive prominence (5) near conductive layer (2) leave a blank so that first insulating barrier (1) and second insulating barrier (2) directly combine.
