Abstract
The invention discloses a thermoelectric separation light-emitting diode (LED) which mainly comprises a main LED body fixed on a base plate, a positive electrode, a negative electrode and a heat sink, wherein the base plate is provided with a drill hole used for arranging the main LED body; the main LED body is arranged in the drill hole of the base plate; and the heat sink is positioned under the main LED body and the heat sink and the two electrodes are not arranged at the same plane. After the thermoelectric separation LED is adopted, the thermal resistance of a system is reduced, and the material cost of a circuit board, the labor cost of installation, the material cost of installation, the labor cost of maintenance, the scrap material cost in maintenance and the thermal conductive adhesive material cost can be saved.
Description
Technical field
The present invention relates to the LED field, say more specifically to relate to a kind of thermoelectric LED of separation.
Background technology
At present, thermoelectric two electrodes of LED that separate of tradition and heat sink at same horizontal plane, thermoelectric two electrodes of LED main body that separate of tradition and heat sink are welded on conplane wiring board.In order to reach radiating effect; The general higher relatively circuit sheet materials of cost such as aluminium base or ceramic substrate that adopt; The heat transfer process that traditional thermoelectricity separates the LED main body is: heat sink-copper foil layer-insulating barrier-aluminum base layer (ceramic layer)-heat-conducting glue-radiator, and the thermoelectric LED that separates of tradition is coated with full and the sizable thermal conductive silicon heat conduction of wiring board with full wafer LED lamp plate usually; The thermoelectric LED that separates of tradition is difficult to dismounting owing to be coated with heat-conducting glue; Even damaged line plate, lamp pearl etc., the thermoelectric LED that separates of tradition directly is welded in the heat sink of LED on the circuit usually, when needing repairing very the difficulty aesthetic measure that very easily destroys product with originally do not have bad element.Tradition is thermoelectric need to be coated with a large amount of heat-conducting glues on the lamp plate or on the aluminium valency plate when separating the assembling of LED lamp plate, and with screw fixedly the amount of causing be difficult to control, many easy effect of floods are attractive in appearance, lacked to cause easily that to have the space to dispel the heat between aluminium base and the radiator bad.
Summary of the invention
(1) the present invention's technical problem that will solve
The object of the present invention is to provide a kind of thermoelectric LED of separation, overcome that the prior art thermal resistance is big, operation is loaded down with trivial details, not attractive in appearance, the defective of waste material.
(2) technical scheme of the present invention
For achieving the above object, a kind of thermoelectric LED that separates provided by the invention mainly comprises the LED main body that is fixed on substrate, two positive and negative electrodes and heat sink; Said substrate is provided with the boring of placing the LED main body; It is inner that said LED main body is arranged on the boring of substrate, said heat sink be arranged on below the LED main body with two electrodes not on same plane.
Further, the said heat sink heat-conducting cream that is provided with.
Further, be sunken to single face epoxy substrate and directly be affixed on the radiator that has shallow slot for said heat sink time.
(3) beneficial effect of the present invention
A kind of thermoelectric LED that separates of the present invention has not only reduced the thermal resistance of system, and has practiced thrift condemned MAT'L cost, heat-conducting glue material cost in wiring board material cost, installation cost of labor, mounting material cost, maintenance cost of labor, the maintenance.
