Abstract
The utility model discloses a take heat radiation structure's high power LED car portable lighter in daytime, including car portable lamp plug socket in daytime, be equipped with the radiating block in the car portable lamp plug socket in daytime, the radiating block is connected with printed circuit board through the copper, printed circuit board passes through the screw lock and pays on the radiating block, printed circuit board is last to be equipped with LED lamp pearl, the copper is filled with the junction of radiating block has the thermal grease. The utility model discloses simple structure utilizes the heat conduction principle, conducts to the air in the heat that gives off of LED lamp pearl in the lamps and lanterns is timely to reduce near the heat in light source, reduce the heat fade of LED lamp pearl.
Description
Technical field
This utility model is related to vehicle light illumination field, more particularly, to a kind of high-capacity LED automobile daytime with radiator structure
Portable lighter.
Background technology
Automobile daytime portable lighter is believed to be helpful in the function of day driving safety, is extensively arranged on car body now, but daytime
Portable lighter has high brightness requirement, and it is higher that this requires the light-source brightness of daytime portable lighter to require, and due to the requirement of energy-conservation, high-capacity LED is made
Light source for daytime portable lighter is widely used, but the Tj temperature of LED is relatively low, if the high heat that LED produces cannot be derived,
The brightness of LED will decay at double, lead to function to lose efficacy, destroy the effectiveness of function.
Utility model content
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides a kind of structure simply, real
High-capacity LED automobile daytime portable lighter with radiator structure.
This utility model is realized in the following way：
A kind of high-capacity LED automobile daytime portable lighter with radiator structure it is characterised in that：Including automobile daytime portable lamp plug socket, institute
State and in automobile daytime portable lamp plug socket, be provided with radiating block 1, described radiating block 1 is connected with printed circuit board (PCB) 3, described printing by copper coin 2
Circuit board 3 passes through screw 6 lock and pays on radiating block 1；Described printed circuit board (PCB) 3 is provided with LED lamp bead 4；Described copper coin 2 and radiating
The junction of block 1 is filled with thermal grease 5；The thickness of described thermal grease 5 is not higher than 0.3mm；If the afterbody of described radiating block 1 is provided with
Cured leaf lamella 7.
The beneficial effects of the utility model are：Structure is simple, using heat conduction principle, by lamp bulb in LED lamp
The heat distributing timely conducts in the air, thus reducing the heat near light source, reduces the heat fade of LED lamp bead.
Brief description
Fig. 1 this utility model structural representation.
Specific embodiment
In conjunction with accompanying drawing in detail, this utility model specific embodiment is described in detail：
As shown in figure 1, a kind of high-capacity LED automobile daytime portable lighter with radiator structure, including automobile daytime portable lamp plug socket, automobile
It is provided with radiating block 1, radiating block 1 is connected with printed circuit board (PCB) 3 by copper coin 2, printed circuit board (PCB) 3 passes through screw in daytime portable lamp plug socket
6 locks are paid on radiating block 1；Printed circuit board (PCB) 3 is provided with LED lamp bead 4；Copper coin 2 is filled with thermal grease with the junction of radiating block 1
5；The thickness of thermal grease 5 is not higher than 0.3mm；The afterbody of radiating block 1 is provided with some blade layers 7.
By thermal grease 5 in copper coin 2 backside（Silicone grease）, possessing insulating properties at the same time it can also play the effect of buffering, profit
With the characteristic of the quick conductive of copper coin 2 and the feature design of rapid heat dissipation, so that heat is quickly conducted to low-temperature space, reduce radiating surface
Long-pending.
The heat conductivity of aluminium sheet is 203W/mk, and the heat conductivity of copper coin 2 is 401W/mk, and the heat conductivity of thermal grease 5 only has 2W/
Mk, for more preferable heat conduction, needs to give full play to buffering and the viscosity of the high-termal conductivity of copper coin 2 and thermal grease 5, the face of copper coin 2
Amassing need to be consistent with printed circuit board (PCB) 3 with shape, and the thickness of thermal grease 5 is not above 0.3mm.
When the high heat conduction of printed circuit board (PCB) 3 causes copper coin 2, heat is quickly conducted and causes on radiating block 1 by copper coin 2,
Because radiating block 1 is big with air contact area, so that high temperature transmission low-temperature space；Printed circuit board (PCB) 3 is added with the combination of radiating block 1
Big area of dissipation, and apply last layer thermal grease 5 in the middle of printed circuit board (PCB) 3 with radiating block 1, make printed circuit board (PCB) 3 and dissipate
The middle gapless of hot block 1, enables heat to be quickly transferred on radiating block 1.The bladed structure of radiating block 1, in limited sky
Between in increase the area of radiating；Increase the contact area with light fixture air.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
The equivalent structure made using this utility model description and accompanying drawing content or equivalent flow conversion, or be directly or indirectly used in
Other related technical fields, are all included in the same manner in scope of patent protection of the present utility model.
