Description

Fast-assembling glass heat pipe LED light fixture

Technical field

The utility model relates to fast-assembling glass heat pipe LED light fixture.LED is that the English of lasing fluorescence diode is called for short, and can be regarded as the generally acknowledged technical term of the art.

Background technology

Adopt the LED light fixture of gravity assisted heat pipe, its general configuration should be conducted heat and connect several LED for the hot junction below heat pipe.The Main Function that heat pipe here rises should be to realize heat flow density conversion and heat radiation.Relevant heat flow density is transformed to roughly and is transformed to approximately 0.06 watt/square centimeter from approximately 0.5 watt/square centimeter.

Investigate existing LED light fixture, for the wide LED for 5*7 millimeter, 0.6 watt of general power, light efficiency 21% of one of them long * and the energy except luminous, all by surface conductive entered environment, LED all surfaces are long-pending, get 1 centimetre of 2(0.5*0.7*2+0.1.25*(7+5+7+5)), its heat flow density of loading of dispelling the heat is 0.6*(1-0.21) 474 watts/centimetre 2 of/1=0..If do not adopt radiator, the surface temperature of LED can be over 100 ℃.

Again, for a heat radiation load, be the LED with radiator of 10 watts, in the flat cubic centimetre of area of dissipation 200 of its spreader surface, its heat radiation power density is 0. 05 watts/centimetre 2.Reference in contrast: the expose to the sun peak strength of penetrating of sunshine is about 1 Qian Wa/㎡ and closes 0.1 watt/centimetre 2.25 watts of incandescent light bulb that surface area is 170 centimetre 2, because glass cell-shell stops and absorption ultrared, obviously rise the temperature on glass cell-shell surface.Here, get 10 watts of heat radiation powers by glass cell-shell, its heat radiation power density of conducting by glass cell-shell is 0.0588 watt/centimetre 2 of 10/170 ≈.

The computing formula of object heat radiation power and heat-delivery surface temperature rise is:

Q=K*ΔT*S…………（1）

In formula 1, Q is heat radiation power, and dimension is watt; K is the heat transfer coefficient from glass heat pipe cold end surface to air, and dimension is watt/(℃ * ㎡); Δ T is the intensification that air is heated, dimension be K or ℃; S is the area of the glass heat pipe cold junction that contacts with air, and dimension is square metre.

By Q=10, K=23 watt/(℃ * ㎡), S=0.02 ㎡ substitution; 21.74 ℃ of the temperature rise Δ T ≈ of described heat dissipation model.When S=0.017 ㎡, obtain 25.58 ℃ of temperature rise Δ T ≈.Here all heat radiation load all with almost average temperature by with air heat-exchange entered environment.In fact, the numerical value of Coefficient K also comprises that with surface state clean conditions is relevant with emissivity.

For LED light fixture, its heat radiation approach from LED to air is complicated more than incandescent lamp.The temperature rise value of 30 ℃ of the relative environment temperatures in LED lamp radiator surface is got to 21.74 ℃, and the temperature of getting Heat Conduction Material between LED and heat pipe hot junction fall 2 ℃, the temperature of heat pipe hot junction tube wall fall 2 ℃, from heat pipe hot junction to the temperature of cold junction two phase flow heat transfer, fall ignore, the temperature of heat pipe cold junction tube wall falls 1 ℃, the surface temperature of known described LED will reach 30+21.74+1+2+2=56.74 ℃.In view of the surface temperature of LED changes with environment temperature and itself heat flow density.When the peak of set environment temperature is that 30 ℃, heat transfer coefficient are set as 23 and the maximum temperature of LED while being 64 ℃, the glass heat pipe cold junction area that every watt of heat radiation power needs is at least 15 square centimeters; Corresponding heat flow density is 0.0667 watt/centimetre 2.Under this operating mode, the LED10 light decay of ten thousand hours is expected lower than 20%; And existing minority LED light fixture inferior only one summer light decay will reach more than 50%.
