Abstract

The utility model discloses an LED (light-emitting diode) tunnel lamp, which comprises a lamp holder, a heat-conducting substrate, an LED light source and a drive power supply. The LED tunnel lamp is characterized in that the lamp holder is directly used as a radiating device; the structure of the radiating device is that a trapezoid frame is arranged on the lamp holder; the heat-conducting substrate is arranged at the upper bottom and two waists of the trapezoid frame; a plurality of radiating risers are arranged inside the trapezoid frame; a gap is preserved between the adjacent radiating risers; two groups of crescent radiating ribs in the same rotation direction are also arranged at the positions corresponding to two sides of the lamp holder; the LED light source is composed of an annular clamp, a lens, a lens rubber ring, an annular clamp rubber ring in a sealing manner; the drive power supply is arranged inside the independent power box; the power box is fixed at the bottom part by virtue of a bolt; two symmetrical convex lugs are arranged on the lamp holder; a handle for fixing the lamp is arranged on each convex lug, and the lens is a free-form surface lens. The LED tunnel lamp disclosed by the application achieves large-range illumination, and the loss problem of the output light of the LED is reduced.

Description

A kind of LED Tunnel Lamp

Technical field

The utility model relates to lighting, relates in particular to the LED Tunnel Lamp.

Background technology

Along with the modernization development of society, railway, highway, industrial and mineral, pedestrian tunnel are increasing, and in narrow and small tunnel space, for guaranteeing traffic safety, then require width of roadway large, the light uniformity is high, the light fixture long service life, thereby lighting had higher requirement.Traditional tunnel light fixture, its structure is the compositions such as heat abstractor, led light source and driving power that comprise lampholder shell and be arranged on enclosure interior, the installation base plate of light source is that a flat board is directly installed on the heat abstractor, and its deficiency is to be unfavorable for adjusting the large-scale lighting angle of led light source; Heat abstractor arranges the housing inner chamber, is unfavorable for Air Flow, has greatly affected radiating efficiency, has shortened the service life of led light source.

Summary of the invention

It is a kind of simple in structure that the utility model provides, good heat dissipation effect, the LED Tunnel Lamp that illumination range is large.

A kind of LED Tunnel Lamp, it comprises lamp socket, heat-conducting substrate, led light source and driving power, it is characterized in that, lamp socket is directly as heat abstractor, the structure of heat abstractor is, ladder-shaped frame is installed on the lamp socket, and heat-conducting substrate is installed on the upper base and two waists of ladder-shaped frame, be provided with several pieces heat radiation risers in the trapezoidal shape framework, leave the gap between every adjacent heat radiation riser; Described lamp socket both sides correspondence arranges and also arranges two groups with the crescent shape radiating ribs of rotation direction; Described led light source is assembled by annular holder, lens, lens cushion rubber, annular holder rubber sealing; Described driving power is arranged at independently in the power pack, and power pack is bolted on the lamp socket bottom, and lamp socket is provided with two symmetrical protruding ears, and lug is provided with for the fixing carrying handle of light fixture; Described lens are free-form surface lens.

Good effect of the present utility model is: the heat that led light source produces conducts to first heat-conducting substrate, reaches lamp socket by substrate again, by free convection and the heat radiation of lamp socket dissipation of heat is fallen.Trapezoidal shape design on the lamp socket so that lighting angle increases, has realized illumination on a large scale, has reduced the loss of LED output light.Gap between the heat conduction riser is conducive to Cryogenic air and directly enters riser formation convection current, has increased greatly exchange area, has improved radiating efficiency.Adopt the toroidal lens luminous intensity distribution, make road illumination even.
