Description

LED straight barrel type bulkhead lamp capable

Technical field

The utility model relates to field of illuminating lamps, relates in particular to a kind of LED straight barrel type bulkhead lamp capable.

Background technology

Along with the reduction of LED cost, the raising of performance, and compare with traditional lighting source and to have the luminous efficiency height, low in energy consumption, long service life, do not have advantages such as ultra-violet radiation, energy-conserving and environment-protective, and be widely used in the illumination of various public places.As all using power height, the strong LED bulkhead lamp capable of brightness in bigger places such as some workshops, factory building, gas station, large supermarket, exhibition center, gymnasium; But because LED is photoelectric device, its course of work has only 15%-25% electric energy to convert luminous energy to, and remaining electric energy nearly all converts heat energy to; The temperature of led light source tool is raise; Especially these powerful bulkhead lamp capables, caloric value is higher, distributes if heat is untimely; Cause the lumen degree of led light source to be decayed easily, shorten its service life owing to overheated.The radiator structure of traditional LED bulkhead lamp capable mostly exists complex structure, installation and processing operation trouble, shortcoming that cost is high.In addition, existing LED bulkhead lamp capable mostly carries out reflective through the reflector layer on the lampshade, and its reflecting effect is bad, and dust accumulates on the reflector layer easily, influences reflecting effect.

Summary of the invention

Therefore, to the problem of above-mentioned existence, the utility model provide a kind of simple in structure, radiating efficiency is high, optical uniformity good, the LED straight barrel type bulkhead lamp capable of long service life.

For solving this technical problem, the utility model is taked following scheme: LED straight barrel type bulkhead lamp capable comprises lamp housing, led light source and driving power; Be provided with reflector in the said lamp housing, said reflector is provided with the LED substrate behind, and said led light source is located on the LED substrate; Said LED substrate is electrically connected with driving power; Said lamp housing opening is provided with a transparent glass, and the lamp housing back side is provided with radiating subassembly with the corresponding position of said LED substrate, and said radiating subassembly comprises heat-dissipating cylinder and groups of fins; Said heat-dissipating cylinder lower end is connected with the lamp housing back side through a radiating bottom plate; Said driving power is located in the heat-dissipating cylinder, and groups of fins is located on the radiating bottom plate, and places said heat-dissipating cylinder inner.

Further, said groups of fins is spaced by several heat radiation aluminium flakes and forms, and the bottom of each aluminium flake that dispels the heat is connected through bolts and nuts and is integral, and the top of fin is provided with " U " type to chute.

Further, said reflector comprises glass body and the cup end, and cup is as bowl-type, and cup body inwall is the reflective surface of circular arc, and the cup end is provided with one makes the led light source body stretch into the perforate of glass body, and the top of reflector is provided with opening.

Further, be provided with a lamp body suspender on the said heat-dissipating cylinder.

Through adopting the aforementioned techniques scheme; The beneficial effect of the utility model is: the utility model is through being provided with heat-dissipating cylinder and groups of fins with the corresponding position of said LED substrate behind at lamp housing; And heat-dissipating cylinder, groups of fins absorb the heat that sends from led light source through radiating bottom plate heat conduction, and the heat that led light source is sent is dispersed in the air fast, in time, make led light source remain on work under the lower state of temperature; The led light source luminous efficiency is high; Can be not too high because of temperature, and cause the decay of lumen degree, long service life; In addition, because a reflector is set in lamp housing, this reflector illumination is even, effectively improves illuminance, and light loss is little, and dust is difficult for accumulating in the reflector, and reflecting effect is good.
