Abstract
The utility model discloses a kind of radiator of high-powered LED lamp, including pedestal, heat exchanging chamber, top cover；Pedestal is provided with conductive fluid, and pedestal and heat exchanging chamber are integrally formed；Centre from pedestal to heat exchanging chamber is provided with threading hole；The sealing space that pedestal and heat exchanging chamber are formed is heat transfer space and is vacuum；The surrounding of heat exchanging chamber, which is divided equally, is equipped with condenser pipe, is fixed with fin on condenser pipe.The utility model structure is simple, and using thermally conductive and convection current, the temperature on chip is distributed, and high-powered LED lamp can work long hours, and the temperature on chip is only high, while methanol can be recycled.
Description
Technical field
The utility model relates to a kind of radiators, more particularly to are a kind of radiators being mounted on high-powered LED lamp.
Background technique
With the continuous development of lighting engineering, the epoch of the continuous maturation of LED illumination System, LED large-scale promotion arrive.
Country, which advocates, carries out reducing energy consumption using EPC mode, and in August, 2014, tunnel illuminating system, which newly standardizes, to come into being, tunnel illumination
Into LED and intelligent dimming epoch, Novel LED lamp intelligence control system becomes next step realistic problem anxious to be resolved.According to
Statistics, it is to be wasted in " excess illumination " that the energy consumption of highway lighting, which has 70% or so, and Ministry of Communications has promulgated new professional standard in 2015
" highway tunnel illumination design details " (JTG/T D70/2-01-2014) general provisions 1.0.7 clear stipulaties: highway lighting should be adjusted
Photocontrol design.During " 12th Five-Year Plan ", Department of Transportation proposes pushes energy conservation to subtract energetically in terms of structure, technology, management three
Row's work continues deeper into development, forms fairly perfect communications and transportation energy-saving and emission-reduction strategical planning system, statutory standard system, system
Meter monitoring checking system and supervision and management system.Currently, LED intelligent dimming technology has had very various applications, LED street lamp
Compared with conventional road lamp luminous efficiency, high, long service life, environmental protection and energy saving are widely used in street lamp and tunnel etc..
Utility model content
Based on the above issues, the purpose of this utility model is that proposing a kind of PWM control device of LED tunnel lamp, pass through
LED street lamp has transient response characteristic, and ground PWM dimming mode can be led on LED drive circuit, to the light on and off of LED tunnel lamp into
Row duty cycle adjustment, to realize the adjusting of lamp brightness.
Technical solution is as follows: the radiator of high-powered LED lamp, including pedestal, heat exchanging chamber, top cover；Pedestal passes through thermal conductive silicon
Glue is fixed on the chip of LED light；Pedestal is cylinder；Heat exchanging chamber is fixed on pedestal；Heat exchanging chamber forms closed with pedestal
Space is heat transfer space and is vacuum；Pedestal and heat exchanging chamber are integrally formed；Threading hole is provided with inside from pedestal to heat exchanging chamber；Bottom
Seat is provided with conductive fluid；Heat exchanging chamber surrounding is divided equally there are four condenser pipe, is fixed with fin on condenser pipe, and the height of fin is from heat exchange
Chamber is gradually got higher outward；Top cover is covered in one end of heat exchanging chamber.
Base diameter is at least twice of the diameter of threading hole.
Heat exchanging chamber is funnel-shaped.
Conductive fluid is one of methanol or acetone or alcohol.
The distance between fin is 5-7mm.
Fin thickness is 0.3mm.
The radiator of the utility model high-powered LED lamp realizes heat dissipation with thermally conductive and convection current two ways, has more preferable
Heat dissipation effect.The confined space that heat exchanging chamber and pedestal are formed is heat transfer space and is vacuum, and it is thermally conductive that methanol is added in the cavities
Liquid, the methanol of pedestal of the amount of heat from LED through radiator, methanol by thermal evaporation, amount of heat with gasification methanol
Toward radiator upper direction, heat constantly passes through heat transfer space and distributes heat toward condenser pipe；At this moment conductive fluid methanol is due to temperature
Decline can liquefy, and flow back to pedestal, prepare for circulation next time.Heat transfer space is vacuum, is more advantageous to heat transfer.Heat exchanging chamber is set
It counts into funnel and opens shape, help sharp conductive fluid and be back to pedestal；Fin on condenser pipe can adopt red copper.Condenser pipe can be used thermally conductive
The good material of coefficient is made, such as high-purity aluminum or aluminum alloy.
