Description
Affiliated technical field
The present invention relates to field of illumination systems, especially, is a kind of LED street lamp.
Background technology
The same with conventional light source, semiconductor light emitting diode (LED) also can produce heat during operation, and how much it depends on whole luminous efficiency.Power up outside under the energy, the radiation recombination generation electroluminescent in electronics and hole, semiconductor medium and encapsulation medium that near the light that PN junction, radiates also need pass through chip (chip) itself just can arrive at external world's (air).Comprehensive electric current injection efficiency, radioluminescence quantum efficiency, chip exterior light take out efficient etc.; Finally probably have only the input electric energy of 30-40% to be converted into luminous energy, the form of the lattice vibration that the energy of all the other 60-70% mainly takes place with non-radiation recombination transforms heat energy.
In general, whether the work of LED lamp is stable, the quality quality, and most important with lamp body heat radiation itself, natural heat dissipation is usually adopted in the heat radiation of high-brightness LED lamp in the market, and effect is unsatisfactory.The LED light fixture that led light source is made is made up of LED, radiator structure, driver, lens, and therefore heat radiation also is a part and parcel, if LED can not finely dispel the heat, its life-span also can be influenced.Usual high-brightness LED generally can adopt aluminium radiating fin or fan to lower the temperature, and simple use aluminium radiating fin cooling temperature is declined by less than the position, if use fan for cooling, often fan has been broken LED and also had very long service life, causes LED to damage.
Summary of the invention
To the problems referred to above, the object of the present invention is to provide a kind of LED street lamp, this LED street lamp can effectively solve the problem of LED heating, takes into account service life simultaneously.
The scheme that technical solution problem of the present invention is adopted is:
This LED street lamp comprises several LED device and shells; Said LED device is fixed on the LED substrate; The one side that said LED substrate is provided with the LED device places in the aluminum reflector, and the cold junction of said LED substrate another side and at least one chip semiconductor cooling piece is adjacent to, and fills full heat-conducting silicone grease between LED substrate and the semiconductor chilling plate; There is a hole said shell lower end; The part of said shell is the design of aluminium matter radiator structure, and the basic plate of said LED, reflector and semiconductor chilling plate place among the said street lamp shell, and said reflector the rim of a bowl and said hole match; Said hole is provided with lampshade; The hot junction of said semiconductor chilling plate is connected with the inner aluminium matter portion of hot of lamp housing, and said lamp housing inside also is provided with the constant voltage electronic module, and LED device and semiconductor chilling plate on said constant voltage electronic module and the LED substrate are electrically connected.
Further, said semiconductor chilling plate can further reduce the temperature of cold junction through the mode that is layering.
Further, said hole circumferentially be provided with rubber seal, prevent that steam from getting into.
Further, the aluminum radiator structure of said street lamp shell is positioned at the middle part of street lamp shell, and the top of street lamp shell and sidepiece all have radiating fin, and the direction of said sidepiece radiating fin is an above-below direction, is convenient to flowing of air.
Beneficial effect of the present invention is: compared to traditional LED lamp; The present invention has adopted semiconductor chilling plate that heat is taken away rapidly, and through the fin on the lamp outer casing heat is scattered and disappeared, and does not shake during owing to semiconductor chilling plate work; Service life is stable, so the whole LED street lamp life-span is stable.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
In the embodiment of Fig. 1-shown in Figure 3; Said LED device 201 is fixed on the LED substrate 202; The one side that said LED substrate 202 is provided with LED device 201 places in the aluminum reflector 203; The cold junction of said LED substrate 202 another sides and a slice semiconductor chilling plate 204 is adjacent to, and fills full heat-conducting silicone grease between LED substrate 202 and the semiconductor chilling plate 204.
In conjunction with Fig. 1 Fig. 2; The LED street lamp includes shell 101; There is a hole said shell 101 lower ends; The part of said shell 101 is aluminium matter radiator structure design, and among said LED reflector 203, LED substrate 202 and semiconductor chilling plate 204 placed said street lamp shell 101 from lower end to the upper end of shell 101, said aluminium matter reflector 203 the rims of a bowl and said hole matched; Said hole is provided with lampshade 103; The aluminium matter radiator structure thermally coupled of the hot junction of said semiconductor chilling plate 204 and lamp housing 101 inside, said lamp housing 101 inside also are provided with constant voltage electronic module 205, and LED device 201 and semiconductor chilling plate 204 on said constant voltage electronic module 205 and the LED substrate 202 are electrically connected.
Above-mentioned LED street lamp, the mode that can adopt the above semiconductor chilling plate 204 cold junctions butt joint hot junction of a slice, hot junction to connect cold junction superposes, and can further reduce the operating temperature of LED street lamp.
Above-mentioned LED street lamp, said hole circumferentially be provided with rubber seal, prevent that steam from getting into.
Above-mentioned LED street lamp, the aluminum radiator structure of said street lamp shell is positioned at the middle part of street lamp shell, and the top of street lamp shell and sidepiece all have radiating fin 102, and the direction of said sidepiece radiating fin 102 is a vertical direction, is convenient to flowing of air.
Above-mentioned LED street lamp is when work, and constant voltage electronic module 205 driving LED devices 201 are luminous, drive semiconductor chilling plate 204 cold junctions simultaneously the heat of LED device 201 is taken away; The heat of taking away is assembled in the hot junction of semiconductor chilling plate 204; The temperature in the hot junction of semiconductor chilling plate 204 raises much than the temperature of LED device 201 at this moment, because the high more heat radiation of temperature is fast more, heat is than mode was lost through the aluminium matter radiator structure on the shell faster originally; Aluminium matter radiator structure on the said shell 101 is because the fin 102 of side adopts the vertical direction setting; Make air accelerate to flow and strengthened radiating effect, do not shake during owing to semiconductor chilling plate 204 operations, protected the Stability Analysis of Structures of street lamp; Simultaneously semiconductor chilling plate 204 has the very long life-span, has guaranteed LED street lamp service life.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
