Abstract
The utility model relates to an LED tunnel illuminating lamp suitable for illumination in a road tunnel, which comprises a metal housing, two end closures, a glass panel movably sealed on the front port of the metal housing, a reflector arranged inside the metal housing and a circuit provided with a plurality of LED light sources. Particularly, a plurality of sheet-shaped radiating flanges are arranged on the outer surface of the metal housing. The utility model has the advantages of simple structure and good radiating performance.
Description
Technical field
The utility model relates to a kind of lighting, particularly a kind of LED tunnel illuminating lamp that is applicable to highway tunnel illumination.
Background technology
At present, highway tunnel illumination usually with high-pressure mercury lamp, straight tube fluorescent lamp, electrodeless florescent lamp as lighting source.But the high-pressure mercury lamp color rendering properties of light source is poor, and work is longer start-up time; The straight tube fluorescent lamp luminous efficiency of source is low, the life-span is shorter.Though and electrodeless florescent lamp has overcome short defective of life-span, because the volume of high-power electrodeless fluorescent tube is bigger, the light at the fluorescent tube back side device that can't be reflected reflexes on effective plane of illumination, and the light efficiency of light fixture is lower.Its high frequency electromagnetic radiation is bigger simultaneously, and the field of employment is restricted.
Adopt LED as vcehicular tunnel lamp lighting source, have advantages such as energy-conservation, that light efficiency is high and the life-span is long.And the tunnel illuminating lamp of prior art, its circuit board that is provided with some led light sources is to be connected with common metal shell inner bottom surface, and the outer back side of this metal shell is the plane, the heat that produces during led light source work is then transmitted to the external world by this metal shell and is distributed.But because the outer surface of this metal shell is less, its heat dispersion is therefore desirable not enough.
The utility model content
The utility model is little at above-mentioned outer surface of outer cover, the unfavorable problem of radiating effect, the LED tunnel illuminating lamp that provides a kind of shell that excellent heat dispersion performance is arranged.
Technical solution of the present utility model is:
A kind of LED tunnel illuminating lamp, comprise a metal shell, two end cap and the movable face glass that is packaged on this metal shell front port, and be located at interior reflector of this metal shell and the circuit board that is provided with some led light sources, it is characterized in that: the outer surface of described metal shell is provided with the number of plate-shaped fin.
Number of plate-shaped fin on the described metal shell outer surface and this metal shell are moldable to be one.The favourable rapid heat radiation of this structure.
The positive back side of described metal shell outer surface can be lengthy motion picture shape fin, and both sides, the back side are short-movie shape fin.The favourable ventilation and heat of this structure, and specious.
The utility model is owing to be provided with the number of plate-shaped fin at the outer surface of metal shell, thereby makes the external surface area of metal shell increase, and radiating effect improves.Therefore, the utlity model has simple in structure and advantage good heat dispersion performance.
Description of drawings
Fig. 1 is the utility model cross section structure schematic diagram.
Fig. 2 is the utility model profile schematic diagram.
The specific embodiment
Among Fig. 1, Fig. 2,1-fin, 2-reflector, 3-LED circuit of light sources plate, 4-metal shell, 6-fin, 6-face glass, 7-end cap.
As shown in Figure 1 and Figure 2, one metal shell 4, two end cap 7 and the movable face glass 6 that is packaged on these metal shell 4 front ports, and be located at the reflector 2 in this metal shell 4 and be provided with the circuit board 3 of some led light sources, the outer surface of described metal shell is provided with number of plate- shaped fin 1 and 5.
Number of plate-shaped fin on the described metal shell outer surface and this metal shell are moldable to be one.The favourable rapid heat radiation of this structure.
The positive back side of described metal shell outer surface can be lengthy motion picture shape fin 1, and both sides, the back side are short-movie shape fin 5.The favourable ventilation and heat of this structure, and specious.
Described reflector 2 can make LED light reflex on the road surface to form stronger even illumination by it.Described two end cap is movably connected in two ends, the metal shell left and right sides, installs so that produce.During application, a connection support also can be installed in addition in the sheet top of falling apart in the positive back side of described metal shell outer surface, uses for installing.
A large amount of heat energy that all LED produce in the utility model work all can outwards distribute on the sheet radiator by lamp outer casing, and the light that LED sends shines the road surface by reflector after reflective, and it has simple in structure and advantage good heat dispersion performance.
Claims (3)
