Description
Technical field
The present invention relates to a kind of heat spreader structures, more particularly to a kind of three-dimensional convection heat radiation light source module group radiator.
Background technology
At present, existing LED lamp sources module, including radiator and luminescence component, sets between luminescence component and radiator
Heat-conducting layer is put, luminescence component is all heat generating component, and the heat that luminescence component is produced first is conducted to heat-conducting layer, then is conducted to radiating
Device.The setting of existing lamp radiator take into account conduction and radiate, thermal convection current is but have ignored in structure design, from without
The problem of chip heat and hot radiator can be solved well, causes because radiator heat can not be quickly radiated, and then band
The temperature for carrying out LED chips (luminescence component) remains high, so that light decay is severe, the problem of light efficiency is relatively low occurs.
It is well known that the shorter radiating efficiency highest of heat dissipation path, is concentrated and temperature close to the nearest local heat of lamp plate
Higher than distal end, so being the problem of we need to solve how in the place reduction light source module operating temperature near lamp plate.
The content of the invention
The purpose of the present invention is that offer one kind solves the above problems, and can effectively reduce light source module operating temperature, make
A kind of slack-off three-dimensional convection heat radiation light source module group radiator of LED chip light decay.

Compared with prior art, the advantage of the invention is that：On the basis of the radiating of bottom plate both sides radiating wing, bottom is added
Plate radiates.
Radiating wing radiating principle is：The heat that luminescence component is produced is conducted to whole light source module group radiator by bottom plate, is dissipated
Vent rib on the hot wing makes the atmosphere temperature rising of surrounding by radiation and expands rising, forms cross-ventilation, makes cold air from side
Face enters both sides radiating wing, forms cross-ventilation inwards upwards, and heat is taken away by convection current, improves dissipating for light source assembly radiator
Hot property；
Bottom plate radiating principle is：Groove is set on bottom plate, led in cell wall by the air vent formation air parallel with radiating wing
Road, it is ensured that air can flow to other end air vent, and punching press radiating bridge or radiating bridge cut-off on air duct from one end air vent,
When air flows to other end air vent from one end air vent, the heat on bottom plate is taken away, radiating bridge and radiating bridge cut-off edge are empty
Gas passage is set, and there is gap, and heat can not only scatter and disappear along air duct, moreover it is possible to be scattered and disappeared from gap.Simultaneously as radiating
There is air flow in the wing, can strengthen the rapid air movement at bottom plate, further the effect of increase bottom plate radiating.
Due to the shorter radiating efficiency highest of heat dissipation path, concentrated close to the nearest local heat of lamp plate and temperature is higher than remote
End, concentrates temperature higher position design heat loss through convection air channel effectively to reduce light source module operating temperature, so of the invention in heat
Increase bottom plate radiating on the basis of being radiated in both sides, three-dimensional heat dissipation mutually promotes, and can preferably reach radiating effect, make bottom plate and
The temperature difference of both sides radiating wing is changed into 2 DEG C, under equal-wattage, bulk temperature reduces by 3 DEG C or so from 3.7 DEG C.
This radiator heat is more than 200W/mK from LED lamp panel to the radiator coefficient of conductivity, and not timely by environmental factor
Between factor influence；This radiator takes full advantage of cross-ventilation radiating multichannel technology, heat radiation effect from structure design
Rate.
