Description
Technical field
The present invention relates to the glass heat pipe LED light fixture that contains coating of titanium dioxide in surface.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 that the hot junction heat transfer below heat pipe connects several LED.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, all get 1 centimetre of 2(0.5*0.7*2+0.1.25*(7+5+7+5 by surface conductive entered environment, LED all surfaces are long-pending for one of them long * is wide for the LED of 5*7 millimeter, 0.6 watt of general power, light efficiency 21% and the energy except luminous)), 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 exceed 100 ℃.
Again, be the LED with radiator of 10 watts for a heat radiation load, 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…………?
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.In the time of 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 more than incandescent lamp complexity.The temperature rise value of 30 ℃ of relative LED lamp radiator surface environment temperatures 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 ℃, 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 ℃, 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%.
Chinese patent 2008200495178 discloses a kind of high power hot pipe LED illuminating apparatus, include LED, pedestal, heat pipe, and be provided with heat abstractor, one side of pedestal is provided with one or more than one LED, and one end of heat pipe is that hot junction is connected with described pedestal, the other end is that cold junction is connected with described heat abstractor.Directly welding or fill heat-conducting silicone grease and without heat transfer medium in the middle of other, thermal resistance is relatively little between heat pipe and pedestal, heat transfer efficiency is high.Have simple in structure, good heat dissipation effect, the feature of reliable operation.But it adopts pedestal heat transfer connection LED that electric insulation layer need to be set and realizes electrical isolation; Its metal heat pipe cold junction configuration radiating fin plate as with the heat exchange interface of air, owing to also having temperature to fall between heat pipe cold junction and radiating fin plate, and the surface temperature of radiating fin plate is inhomogeneous, thereby has increased dispel the heat link and the heat exchange thermal resistance with air; Fin produces cost and is not easy to clean; Between metal heat pipe hot junction and LED, needing withstand voltage higher insulating barrier, itself there is thermal resistance in insulating barrier.LED surface is because of large, the same thermal resistance of heat flow density, and temperature is fallen can be many greatly.Because LED is to responsive to temperature, temperature exceedes 65 ℃ of LED can very fast decline.Therefore, cut down heat transfer link and the thermal resistance of the link that reduces to conduct heat just significant.
