Abstract
The utility model discloses a thermoelectric separation LED (light-emitting diode), mainly comprising an LED main body fixed on a substrate, a positive electrode, a negative electrode and a heat sink, wherein a drill hole for placing the LED main body is arranged on the substrate, the LED main body is arranged in the drill hole of the substrate, the heat sink is arranged below the LED main body and in different planes with the two electrodes, and the heat sink is arranged on a heat radiator which is located below the LED main body and in different planes with the two electrodes, and used for the heat sink sinking on the substrate and directly clinging to. By adopting the thermoelectric separation LED, the thermal resistance of a system is reduced, and the material cost of a circuit board, the labour cost of installation, the material cost of installation, the labour cost of maintenance, the cost of scrap materials during maintenance, and the material cost of a heat-conducting adhesive are saved.
Description
Technical field
The utility model relates to the LED field, relates in particular 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.
The utility model content,
(1) the utility model technical problem that will solve
The problem that the utility model will solve provides a kind of thermoelectric LED of separation, and thermal resistance is big in the prior art, operation is loaded down with trivial details to overcome, and is not attractive in appearance, the defective of waste material.
(2) technical scheme of the utility model
For achieving the above object, the utility model provides a kind of thermoelectric LED of separation, 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, below the said heat sink LED of the being arranged on main body with two electrodes the said heat sink radiator that is sunken to substrate and directly is affixed on down not on same plane.
Further, the said heat sink heat-conducting cream that is provided with.
Further, said heat sink down be sunken to substrate and directly be affixed on have the radiator of owing groove.
(3) beneficial effect of the utility model
Compared with prior art, the technical scheme of the utility model has the following advantages:
A kind of thermoelectric LED that separates of the utility model has not only reduced the thermal resistance of system, and has practiced thrift condemned MAT'L cost, heat-conducting glue (fat) material cost in wiring board material cost, installation cost of labor, mounting material (heat-conducting glue, fat) cost, maintenance cost of labor, the maintenance.
Description of drawings
Fig. 1 is the overall diagram of a kind of thermoelectric LED of separation of the present invention.
Fig. 2 is the assembly drawing of a kind of thermoelectric LED of separation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
As depicted in figs. 1 and 2, a kind of thermoelectric LED that separates mainly comprises substrate 4, is fixed on LED main body 1 and two positive and negative electrodes 2 of substrate 4; Said two electrodes 2 are welded on the pad 7 on the substrate; Substrate 4 is provided with the boring 5 of placing LED main body 1; Said heat sink 3 are arranged on below the LED main body 1, and are provided with heat-conducting cream 8 below heat sink 3, and said LED main body 1 is arranged on boring 5 inside of substrate 4; Be sunken to substrate 4 and directly be affixed on the radiator 6 that has shallow slot for said heat sink 3 times.The said thermoelectric LED heat transfer process that separates is: heat sink 3-heat-conducting cream 8-radiator 6.
A kind of thermoelectric LED that separates of the utility model has not only reduced the thermal resistance of system, and has practiced thrift condemned MAT'L cost, heat-conducting glue (fat) material cost in wiring board material cost, installation cost of labor, mounting material (heat-conducting glue, fat) cost, maintenance cost of labor, the maintenance.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
