Abstract
The utility model relates to the field of lighting fitting technology and specifically relates to a light-emitting diode (LED) lamp with a directly-welded fixed aluminum substrate. In the light-emitting diode lamp, insulated glass fibers are provided with a hollow hole which is directly communicated with a heat conduction core at a heat conduction core of the lamp particle, and the hollow hole is provided with solder alloy by which the aluminum substrate and the heat conduction core are directly connected. When the LED lamp works, heat generated by the lamp chip is conducted to the metal heat conduction core and then conducted to the solder alloy through the metal heat conduction core. As the solder alloy belongs to metal materials, the solder alloy has small heat resistance and strong heat conduction capacity, and can rapidly conduct heat to the aluminum substrate for heat dissipation so as to guarantee normal work of the LED and prolong service life, and occurrence of a fire disaster caused by concentrated heat is avoided.
Description
Technical field
The utility model relates to field of illumination lamp technology, refers in particular to the LED light lamp that aluminium base is decided in straight solid welding.
Background technology
LED light lamp (LED lamp) uses at lighting field because power saving lowers consumption widely; The caloric value of LED light lamp lamp grain 1 is very big; Except comprising photogenic granules, electrode pin, also be provided with heat conduction core 11 in the design of common diode lights lamp grain 1, heat conduction core 11 is concentrated the heat that photogenic granules produces; Generally; In LED light lamp, the lamp grain 1 of diode lights is arranged on the aluminium base 5 through circuit pad 2, copper plate 3 and insulation glass 4 successively, and aluminium base 5 is connected to radiator 6 (as shown in Figure 1) through thermal conductive silicon glue-line 10.

The utility model content
The utility model is to connect the aluminium base not smooth problem that causes dispelling the heat to the heat conduction core of present LED light lamp lamp grain through the bigger material of thermal resistance, and provides the straight solid welding that overcomes the above problems to decide the LED light lamp of aluminium base.
For achieving the above object, the utility model adopts following technical scheme:
The LED light lamp of aluminium base is decided in straight solid welding, and the lamp grain of said LED light lamp is arranged on the aluminium base through circuit pad, copper plate and insulation glass successively, and aluminium base connects radiator; Said insulation glass is provided with the hollow hole of straight-through heat conduction core at the heat conduction core place of lamp grain, solder alloy is set on the hollow hole directly connects aluminium base and heat conduction core.
Wherein said aluminium base is outwards setting gradually nickel coating, is directly welding copper plate with the one side that contacts of insulation glass.
Wherein said solder alloy is the silver-colored ashbury metal of argentiferous 2%.
Wherein said radiator is provided with pit bit, and aluminium base is embedded on radiator through pit bit.
The beneficial effect of the utility model is: the LED light lamp of the utility model, and the insulation glass is provided with the hollow hole of straight-through heat conduction core at the heat conduction core place of lamp grain, solder alloy is set on the hollow hole directly connects aluminium base and heat conduction core; When LED light lamp was worked, the heat that the heating of lamp grain produces was transmitted to metal thermal conductance core, conducts heat to solder alloy through the thermal conductance core, and solder alloy belongs to metal material, and thermal resistance is less, and capacity of heat transmission is strong; And conduct heat to aluminium base rapidly and dispel the heat, ensure the operate as normal of LED light lamp, increase the service life, to avoid concentrating because of heat, the situation of initiation fire takes place.
