Abstract
The utility model relates to LED (Light-emitting Diode) illumination equipment, in particular to an LED light source module. The LED light source module comprises LED lamp beads, an electrically insulating PCB (Printed Circuit Board) and a radiator, wherein the PCB is in circuit connection with anodes and cathodes of the LED lamp beads; a nickel plating layer electroplated on the surface of the radiator and a tin cream layer printed on the surface of the nickel plating layer are arranged between the radiator and the PCB sequentially; through holes capable of allowing bases of the LED lamp beads to pass though are formed in the PCB; and the bases of the LED lamp beads penetrate through the through holes of the PCB to be in contact welding with the tin cream layer. The LED light source module allows the service lives of the LED lamp beads to be prolonged, reduces light decay, improves the light efficiency, reduces product temperature rise, improves the working efficiency and allows an illumination effect to be good.
Description
Technical field
The utility model relates to a kind of led light source module.
Background technology
Led light source has low energy consumption, high life, advantage such as durable, replaces traditional incandescent lamp and electricity-saving lamp day by day, becomes lighting source of new generation.Yet along with the increase of power, led light source produces a large amount of heat energy, if heat energy can't effectively distribute, along with the increase of service time and number of times, luminous efficiency can seriously descend, and causes the LED life termination.Therefore heat dissipation problem is the key factor in restriction LED life-span.
Traditional led light source is to be connected with radiator with heat-conducting silicone grease by aluminium base, thereby realizes the heat radiation purpose.But aluminium base and heat-conducting silicone grease can cause serious thermal resistance, the insufficient heat conductivity ideal.
The utility model content
Technical problem to be solved in the utility model provides the higher led light source module of a kind of radiating efficiency.
Technical problem to be solved in the utility model is achieved by the following technical programs:
A kind of led light source module, comprise LED lamp pearl, the pcb board of the electric insulation that is connected with LED lamp pearl positive and negative electrode circuit, radiator, be followed successively by the nickel coating that is plated on spreader surface, the tin paste layer that is printed in the nickel coating surface between described radiator and the pcb board, described pcb board has the through hole that the base that can make LED lamp pearl passes through, and the through hole that the base of LED lamp pearl passes pcb board contacts welding with tin paste layer.
For the purpose that reduces cost, described radiator is at a topical nickel galvanization close with pcb board, and nickel coating is plated on the position of the through hole correspondence of pcb board.
Further, described LED lamp pearl is covered with lens.
Further, be provided with water proof ring between described LED lamp pearl and the lens.
Further, described LED lamp pearl is LED high-power lamp pearl.
The utlity model has following beneficial effect:
The utility model is broken through existing LED lamp pearl and is connected to come the mode of heat conduction and heat radiation by aluminium base and heat-conducting silicone grease and radiator, and direct base with LED lamp pearl is welded on the radiator with tin cream.(thermal conductivity factor of tin cream is: 30～50 W/mK because the heat transfer efficiency of tin cream will be far superior to heat-conducting silicone grease, and the thermal conductivity factor of heat-conducting silicone grease only is: 1.5W/mK), therefore the serious thermal resistance that adopts tin cream that LED lamp pearl and radiator are welded will to reduce greatly traditional aluminium base and heat-conducting silicone grease to cause is improved thermal resistance high temperature to the injury that pearl produces of LED lamp.The utility model can reduce the thermal conductivity/reduction thermal resistance more than 20%, and the life-span of LED lamp pearl is prolonged, and reduces light decay, improves light efficiency, reduces the product temperature rise, increases work efficiency, and makes good illumination effect.Can be applicable to various families inside/outside high-power LED illumination project light fixture technology.
Description of drawings
Fig. 1 is blast structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, a kind of led light source module comprises LED lamp pearl 5, and the pcb board 4(of the electric insulation that is connected with LED lamp pearl 5 positive and negative electrode circuits contains the FR4 sheet), radiator 1.Be followed successively by the nickel coating that is plated on spreader surface, the tin paste layer 2 that is printed in the nickel coating surface between described radiator and the pcb board, described pcb board 4 has the through hole 3 that the base that can make LED lamp pearl 5 passes through, and the through hole 3 that the base of LED lamp pearl 5 passes pcb board 5 contacts welding with tin paste layer 2.Above-mentioned nickel coating is plated on the radiator position corresponding with the through hole 3 of pcb board, and the mode of this topical nickel galvanization can reduce cost, and spreader surface nickel plating can make the low temperature tin cream have solderability at radiator 1.This LED lamp pearl 5 can be used large-power LED light bead, and LED lamp pearl is covered with lens 7, and water proof ring 6 is set between the two.
Above-mentioned led light source module is owing to cancelled aluminium base and the heat-conducting silicone grease that traditional LED heat radiation is adopted, directly be welded on the radiator but LED lamp pearl base is passed in the through hole of offering on the pcb board with tin cream, because the thermal conductivity factor of tin cream is significantly higher than aluminium base and heat-conducting silicone grease, therefore can significantly reduce thermal resistance high temperature to the injury of LED lamp pearl, thereby make the illuminating effect of LED lamp pearl better, the life-span prolongs.
The above embodiment has only expressed embodiment of the present utility model; it describes comparatively concrete and detailed; but can not therefore be interpreted as the restriction to the utility model claim; as long as employing is equal to the technical scheme that the form of replacement or equivalent transformation obtains, all should drop within the protection domain of the present utility model.
