Abstract
The utility model discloses an LED (light emitting diode) tunnel lamp which comprises explosion-proof glass, an LED lamp and a shell, wherein the explosion-proof glass is arranged at the top end of the shell, and the LED lamp is arranged in the shell. The LED tunnel lamp is characterized in that the shell is further internally and fixedly provided with a cooling aluminium sheet, a circuit board and a switch power supply, wherein the circuit board is fixed at the back of the cooling aluminium sheet and is connected with the switch power supply by a lead, and the outer surface of the shell is provided with cooling fins arranged at intervals. The LED tunnel lamp is good in cooling performance, and a light resource can not be damaged due to heat, so that the service life of the tunnel lamp can be ensured.
Description
Technical field
The utility model relates to field of illuminating lamps, specifically is meant a kind of LED Tunnel Lamp.
Background technology
Semiconductor illuminating light source is as novel solid state light emitter, will become on the human illumination history light source of another Dai Xin after incandescent lamp, fluorescent lamp, and semiconductor lighting power consumption is 1/8 of incandescent lamp; Be 1/2 of fluorescent lamp, its life-span is about 30-50 times of incandescent lamp, is 10-20 times of fluorescent lamp; As energy-conservation and " rich ore " environmental protection, semiconductor lighting has obtained fast development in recent years, and conventional tunnel lamp in the market all is to be main with yellow high-pressure mercury lamp; There is following defective in the conventional tunnel lamp: because the high-pressure mercury lamp energy consumption is quite high; Caloric value is big, especially non-stop run in 24 hours, and the generation great amount of heat can't be distributed and caused light source short service life.
The utility model content
The purpose of the utility model is to overcome above-mentioned weak point of the prior art, provides that a kind of radiating rate is fast, the LED Tunnel Lamp of long service life.
The purpose of the utility model realizes through following technical scheme:
A kind of LED Tunnel Lamp; Comprise implosion guard, LED lamp and housing, implosion guard is installed in the top of housing, and the LED lamp is located in the housing; Also be installed with heat-dissipating aluminium plate, wiring board and Switching Power Supply in the said housing; Wiring board is fixed in the back side of heat-dissipating aluminium plate, and connects Switching Power Supply through lead, and the outer surface of said housing is interval with fin.
Said LED lamp is arranged by several light emitting diodes and is arranged on the heat-dissipating aluminium plate.
Said housing is integrated, by an extrusion modling of thermal conducting material.
Press a kind of LED Tunnel Lamp of the technical scheme design of the utility model, the heat that the work of LED lamp is produced distributes through heat-dissipating aluminium plate, and the LED lamp can not guarantee service life because of heating damages; And the outer surface of housing is interval with fin, and the heat that whole lamp body produces all can be dispersed into the outside through fin, has more increased the heat dispersion of the utility model.
The utility model compares that prior art has the following advantages and beneficial effect: simple in structure; Reasonable in design; Good heat dissipation effect; The light beam far firing range, long service life can be widely used in because of its higher luminous efficiency on the tunnel, stadium, station terminal, square greenbelt lighting of highway and common road.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but the embodiment of the utility model is not limited thereto.
Embodiment
A kind of LED Tunnel Lamp as shown in Figure 1; Comprise implosion guard 1, LED lamp 2 and housing 3, implosion guard 1 is installed in the top of housing 3, and LED lamp 2 is located in the housing 3; Also be installed with heat-dissipating aluminium plate 4, wiring board 5 and Switching Power Supply 6 in the said housing 3; Wiring board 5 is fixedly connected on the back side of heat-dissipating aluminium plate 4, and connects Switching Power Supply 6 through lead 7, and the outer surface of said housing 3 is interval with fin 8.
Said LED lamp 2 is arranged by several light emitting diodes and is arranged on the heat-dissipating aluminium plate, and present embodiment is selected the special-purpose LED light emitting diode of big diffusion angle super brightness for use, has strengthened the luminosity of LED lamp 2.
The heat that produces during 2 work of LED lamp can distribute through heat-dissipating aluminium plate 4, makes LED lamp 2 can not guarantee service life because of heating damages.
In order to improve radiating effect, the outer surface of housing 3 is interval with fin 8, and the heat that whole lamp body produces all can be dispersed into the outside through fin 8, perfect heat-dissipating.
Said housing 3 is integrated, by an extrusion modling of thermal conducting material.
The foregoing description is the utility model preferred implementation; But the embodiment of the utility model is not restricted to the described embodiments; Other any do not deviate from change, the modification done under spirit and the principle of the utility model, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within the protection domain of the utility model.
