Description
Technical field
The utility model relates to mine lighting device, is specially mining LED tunnel lamp.
Background technology
The LED illuminating lamp is more energy-conservation 90% than conventional lights, is the desirable lighting source under the coal mine.LED is photoelectric device, has only 15%～25% electric energy to convert luminous energy in its course of work, and remaining electric energy nearly all converts heat energy to, and the temperature of LED is raise.In great power LED, heat radiation is a big problem.Unfavorable if dispel the heat, the device core temperature of great power LED can rise rapidly, and when its junction temperature rises above maximum allowable temperature (generally being 150 ℃), great power LED can damage because of overheated.The existing LED tunnel lamp that is used under the coal mine, its design shape are essentially two big classes: circular and microscler.But LED tunnel lamp is because requirement of explosion, often heat radiation is considered not enough to the LED junction temperature, it is that the fluorescent tube of former daylight tunnel lamp is taken out for a for example microscler LED tunnel lamp, there is the led light source of heat radiation to put into glass tube with one, be unfavorable for very much the heat radiation of LED, this will directly influence the service life and the luminous efficiency of led light source.
Summary of the invention
The utility model is unreasonable in order to solve existing mining LED tunnel modulated structure, thereby it is relatively poor to dispel the heat, and then directly influences the service life of led light source and the problem of luminous efficiency, and a kind of mining LED tunnel lamp is provided.This is mining, and LED tunnel lamp radiating effect is remarkable, can satisfy the heat radiation requirement of great power LED.
The utility model is to adopt following technical scheme to realize: mining LED tunnel lamp, comprise base, and described base comprises base plate, and an end face of base plate is provided with radiating ribs, and the centre of base plate other end is fixed with the led light source assembly; The led light source assembly by strip (aluminium) substrate, be fixed in the led light source on the strip substrate and have the led light source hole on it and constitute with the fixing reflector of (aluminium) substrate, (aluminium) substrate is fixed on the end face of base plate of base; The base plate of base is fixed with on the end face of light source assembly and has the connecting line guide hole (being used to draw the wiring of led light source) that leads to bottom end; Base plate is fixed with that sealing and fixing has translucent cover on the end face of light source assembly.During work, the heat that led light source produces passes to base plate through (aluminium) substrate, through base plate and on radiating ribs distribute.An end that has the connecting line guide hole at the base plate of base is provided with cavity, and cavity end sealing and fixing has the lid which is provided with the explosion-proof wiring mouth.Can place various control circuits (control circuit that comprises LED tunnel lamp self) in the cavity, gather in the lamp of LED tunnel for various control circuits and lay a good foundation.The lead-out wire of each control circuit can be drawn in the explosion-proof wiring mouth on the lid in the cavity.
Mining LED described in the utility model tunnel lamp is packaged in led light source one side of base, make outside the radiator portion (radiating ribs) of base opposite side is exposed to, the junction temperature temperature of LED can directly shed by the radiator portion of base, satisfying under the situation of explosion-proof designing requirement, greatly improve radiating effect, can realize the heat radiation of great power LED.After tested during 18W LED full power operation, 35～40 ℃ of spreader surface temperature.Reached design and operational requirement.The various control circuits that are set to of base upper cavity are gathered in the lamp of LED tunnel and are laid a good foundation.This is mining, and LED tunnel modulated structure is reasonable in design, novel, and good heat dissipation can improve the service life and the luminous efficiency of led light source.
