Abstract

The utility model discloses a light-emitting diode (LED) mining lamp, which comprises a power source box, a radiator, a heat conducting column, an LED luminous module, a reflection cover, a diffusing cover and a lamp shade. The reflection cover is arranged at the end portion of the radiator, the diffusing cover is fixed on the reflection cover, a space is reversed between the reflection cover and the lamp cover, and a hole is arranged on the lamp shade. The heat conducting column is arranged in the radiator and forms a boss at one end of the radiator, and the LED luminous module is tightly adhered onto a plane of the boss of the heat conducting column. The LED luminous module is arranged in a radiating assembly, and simultaneously the LED mining lamp is provided with the reflection cover, the diffusing cover and the lamp shade correspondingly so that the heat generated by a heat source LED module can be rapidly transmitted into various positions of the front end and the rear end of the radiator through the heat conducting column, and then the air can form circulating convection through the space between the lamp shade and the reflection cover and the air inlet hole on the lamp cover. Accordingly, the heat on the radiator can be taken away quickly and radiation can be improved.

Description

A kind of LED bulkhead lamp capable

Technical field

The utility model relates to a kind of bulkhead lamp capable, relates in particular to a kind of LED bulkhead lamp capable.

Background technology

LED is a kind of solid-state semiconductor device that can electric energy be converted into visible light; It can directly be converted into light to electricity; It has obtained application more and more widely at lighting field; The advantage of LED lamp comprises high brightness, low energy consumption, environmental protection, operating voltage is low, power consumption is little, the life-span is long and characteristics such as stable performance, and the LED bulkhead lamp capable is mainly used in industrial and mining enterprises' factory building, storehouse, toll station, gas station, large supermarket, exhibition center, gymnasium and other needs the place of accent light.Mostly there is the problem of chip cooling and radiator structure design in current general great power LED bulkhead lamp capable, generally only directly contacts etc. as heat abstractor with aluminium section bar and thermal source, and heat dissipation conductor quantity is little; Contact area is little, and can not form the circulative convection of air aloft, and heat dispersion is bad; It is less particularly to work as the thermal source area; When the aluminium section bar area was big, not only thermal source can not directly contact with heat sink section bar fully, can not lead away fully by the heat that thermal source is all; And the heat on the heat sink section bar is difficult to distribute timely because of the convection current that does not have air, and light source life is reduced greatly.

Summary of the invention

The utility model can not be derived to the heat that LED illuminating module in the prior art produces timely and effectively, makes the temperature at led light source place exceed its PN junction temperature, thereby has a strong impact on the defective in led light source life-span, and a kind of LED bulkhead lamp capable is provided.

In order to solve technique scheme, the utility model is realized through following technical scheme:

A kind of LED bulkhead lamp capable; Comprise power pack, radiator, heating column, LED illuminating module, reflection shield, diffusion shell, lampshade; Described reflection shield is inserted the radiator end; Described diffusion shell is fixed on the reflection shield, between described reflection shield and the lampshade spacing is arranged, and described lampshade is provided with the hole.

Heating column is similar to heat pipe, utilizes heat pipe principle to make the heat energy of LED illuminating module import each position, radiator front and back end fast into through plume, thereby greatly reduces the heat on the LED illuminating module.Reflection shield is inserted the radiator end; Diffusion shell is fixed on the reflection shield, make light softer, more uniformly to space divergence, and can not produce dazzling situation; Lampshade is inserted and is formed a determining deviation between radiator end and the reflection shield; Utilize the hole on its spacing and the lampshade, make air form circulative convection, thereby take away the heat on the radiator fast.

Above-mentioned described heating column is inserted in the radiator, and forms boss at radiator one end, and described LED illuminating module is close to heating column boss plane.

Spacing is 6-20mm between above-mentioned described lampshade and the reflection shield, and optimal selection is 10mm.

The diameter in hole is 3-20 mm on the above-mentioned described lampshade, and optimal selection is 10mm.

The utility model incorporates the LED illuminating module in the radiating subassembly; Be equipped with corresponding reflection shield, diffusion shell and lampshade simultaneously; Thereby the heat that makes thermal source LED module produce can import each position, radiator front and back end into through heating column fast, then passes through suitable air admission hole on suitable spacing and the lampshade between lampshade and the reflection shield again, makes air formation circulative convection; Thereby take away the heat on the radiator fast, improved heat dissipation problem greatly.
