Description

A kind of glass heat pipe LED lamp

Technical field

The present invention relates to a kind of glass heat pipe LED light fixture of surface containing coating of titanium dioxide.LED is that the English of lasing fluorescence diode is called for short, and can be regarded as the technical term that the art is generally acknowledged.

Background technology

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

Investigate existing LED light fixture, for the wide LED for 5*7 millimeter, general power 0.6 watt, light efficiency 21% of one of them long * and energy except luminescence except all by surface conductive entered environment, LED all surfaces is long-pending gets 1 square centimeter (0.5*0.7*2+0.1.25*(7+5+7+5)), its heat flow density of dispelling the heat load is 0.6*(1-0.21)/1=0. 474 watts/square centimeter.If do not adopt radiator, the surface temperature of LED can more than 100 DEG C.

Again, be the LED of the band radiator of 10 watts for a heat radiation load, with the flat cubic centimeter of area of dissipation 200 of its spreader surface, then its heat radiation power density is 0. 05 watts/square centimeter.Reference in contrast: the expose to the sun peak strength of penetrating of sunshine is about 1 Qian Wa/㎡ and closes 0.1 watt/square centimeter.25 watts of incandescent light bulb of surface area 170 square centimeters, because glass cell-shell is to ultrared stop and absorption, make the temperature on glass cell-shell surface obviously rise.Here, get the heat radiation power 10 watts by glass cell-shell, then it is 10/170 ≈ 0.0588 watt/square centimeter by the heat radiation power density that glass cell-shell conducts.

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

Q=K* Δ T*S ... (formula 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/(DEG C * ㎡); Δ T is the intensification of air heats, dimension be K or DEG C; S is the area of the glass heat pipe cold junction contacted with air, and dimension is square metre.

By Q=10, K=23 watt/(DEG C * ㎡), S=0.02 ㎡ substitutes into; Obtain the temperature rise Δ T ≈ 21.74 DEG C of described heat dissipation model.Temperature rise Δ T ≈ 25.58 DEG C is obtained as S=0.017 ㎡.Here all heat radiation loads all with almost average temperature by with air heat-exchange entered environment.In fact, the numerical value of Coefficient K also comprises clean conditions with surface state and emissivity is relevant.

For LED light fixture, its sinking path from LED to air is complicated more than incandescent lamp.The temperature rise value of LED lamp radiator surface relative ambient temperature 30 DEG C is got 21.74 DEG C, and the temperature of getting Heat Conduction Material between LED and heat pipe hot junction falls 2 DEG C, the temperature of heat pipe hot junction tube wall falls 2 DEG C, fall from heat pipe hot junction to the temperature of cold junction two phase flow heat transfer ignore, the temperature of heat pipe cold junction tube wall falls 1 DEG C, then the surface temperature of known described LED will reach 30+21.74+1+2+2=56.74 DEG C.In view of the surface temperature of LED changes with environment temperature and the change of itself heat flow density.When the peak of set environment temperature be 30 DEG C, heat transfer coefficient be set as 23 and the maximum temperature of LED be 64 DEG C time, 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/square centimeter.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%.
