The utility model resolves problems of heat radiation complex system, low heat radiation effect of high-power LEDs.
Description
Technical field
The utility model relates to a kind of high-power light emitting LED lighting device of based semiconductor refrigeration radiating.
Background technology
Semiconductor light-emitting-diode (being called for short LED) is as the novel illumination light source, have remarkable advantages such as long, energy-conservation, safety of life-span, environmental protection, rich color, microminiaturization, power consumption only is 1/10 of an ordinary incandescent lamp under the same brightness, and the life-span but can reach 100 times, is about to cause new illumination revolution.
Illuminating LED must adopt high light large power LED, the caloric value of great power LED is lower powered tens of times, if a great power LED does not have cooling system, 10-20 second is will Yin Wendu too high and burn out, and it is about 1% that 1 ℃ of the every rising of temperature, luminous intensity reduce, wavelength change 0.2-0.3nm, cause photochromic variation, the heat dissipation problem of high-capacity LED becomes one of important technology bottleneck of high-power LED illuminating lamp development.
The utility model content
For solving the heat dissipation technology problem that existing illumination exists with high-capacity LED, the utility model provides a kind of high-power light emitting LED lighting device of based semiconductor refrigeration radiating of simple in structure, good heat dissipation effect.
The technical scheme that the utility model solves the problems of the technologies described above is: comprise active semiconductor chilling plate, great power LED, fin, successively that great power LED, active semiconductor chilling plate, fin is bonding from top to bottom, and active semiconductor chilling plate cold junction connects great power LED, and active semiconductor chilling plate hot junction connects fin.
In the high-power light emitting LED lighting device of above-mentioned based semiconductor refrigeration radiating, described active semiconductor chilling plate is provided with a plurality of great power LEDs.
Technique effect of the present utility model is: the utility model is used active Refrigeration Technique, semiconductor chilling plate is placed between great power LED luminous tube and the fin, fin can adopt single fin or be with small fan fin, each contact-making surface adopts silica gel or the good material adhesive of other heat conductivilitys, in 5 seconds, form cold junction during the semiconductor chilling plate energising rapidly, reach the high heat that the high-speed transfer great power LED produces, form efficient highly reliable heat dissipation channel, the luminous PN of realization high-capacity LED temperature successively minimizes.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the utility model comprises great power LED 1, active semiconductor chilling plate 3, fin 5, between active semiconductor chilling plate 3 and the great power LED 1, use silica gel (2 between great power LED 1 and the fin 5, the good material adhesive of heat conductivility such as 4), and active semiconductor chilling plate cold junction connects great power LED, active semiconductor chilling plate hot junction connects fin, when semiconductor chilling plate is switched on, can take away the heat that high-capacity LED produces rapidly, by fin or with fan combination heat is distributed again, guarantee that great power LED cooling is unimpeded, also need not to increase huge spare system and reach the refrigeration purpose.
According to the requirement of LED brightness of illumination, determine the power of single high-powered LED lamp, as 3W, 5W etc., determine the quantity of high-powered LED lamp array distribution.
Selecting the model of semiconductor refrigerating according to the quantity of LED watt level and LED is maximum temperature difference electric current, operating voltage, appearance and size etc.As its appearance and size 40 * 40 * 4.7 of TEC1-12703, can place 4 3W or 5W great power LED simultaneously.
This example energising back system radiating is functional, not too fast because of the bad optical attenuation that dispels the heat, and reaches the great power LED cooling requirement fully.
