Abstract

The utility model relates to an LED jacklight which adopts aluminum sectional material to make a lamp housing so as to simplify the structure of the jacklight, meanwhile, a high-power LED luminous element is directly attached on the inner surface of the lamp housing so that the heat generated by an LED chip is transferred to heat dissipation fins on the outside surface of the lamp housing in short path and then quickly dissipated into the air outside the jacklight, the temperature rise of the LED chip is maintained on a low level so as to achieve the aim of slowing down the light decay process and prolonging the service life. The technical proposal of the utility model can reduce the cost of the jacklight and prolong the service life of the jacklight, and has good social and economic benefits.

Description

A kind of LED lamp

Technical field

The utility model relates to lighting device, is specifically related to the LED lighting technical field.

Background technology

The LED lighting engineering got rapid development in recent years, the lighting that particularly adopts the great power LED light emitting diode to make has had many structure styles to ask the city, but be subjected to the limitation of fitting structure design mostly, cause the LED heat radiation bad, this will cause the LED light decay to accelerate, the lost of life, severe patient will be easy to burn out LED, so the heat dissipation design of high-power LED lamp is a vital problem.

Goal of the invention

The purpose of this utility model is exactly to make improvement to the heat conduction and heat radiation performance of LED lighting, designs the well behaved LED lighting of a kind of heat conduction and heat radiation.

Summary of the invention

Technical solution of the present utility model is, lamp housing is made by aluminium matter or aluminium alloy extrusions, the outer surface design of this aluminium section lamp housing has some radiating fins, the LED light-emitting component directly is mounted on the inner surface of this aluminium section lamp housing, said LED light-emitting component can be packaged great power LED light emitting diode, also can be directly to be encapsulated by light-emitting diode chip for backlight unit to form on described lamp housing inner surface.Other constitutes necessary spare and accessory parts of utility lamp and technology essential factor, adopts prior art to get final product supporting solution.

Technique effect

After adopting technical solutions of the utility model, because LED directly is mounted on the inner surface of lamp housing, the heat that LED produces when work is transmitted on the radiating fin through very short path by the inner surface of lamp housing, give the lamp outer air by the surface conductive of radiating fin again, the lamp outer air is constantly flowing, thereby constantly take away heat energy on the lamp housing, make the temperature stabilization of lamp housing and led chip can not rise too high a lower level, the heat conductivility of aluminum material is better, though not as copper material, but its cost is more copper much lower, thereby the cost performance height, adopt aluminium section bar to do the structural design that lamp housing has further been simplified light fixture again, reduced the cost of light fixture, therefore the utility model scheme makes that the simple in structure and heat conduction and heat radiation of LED light fixture is functional, and then improves the life-span of light fixture.

Description of drawings

Fig. 1 is the cross sectional representation of the utility model embodiment light fixture;

Fig. 2 is the schematic top plan view of the utility model embodiment light fixture.

The specific embodiment

See also accompanying drawing, the lamp housing 1 of technical solutions of the utility model LED light fixture is made for aluminium section, its outer surface has the radiating fin 2 of some quantity, for the ease of just connecting LED, negative the two poles of the earth, there is the special printed circuit board (PCB) 4 of a punching to be mounted on the inner surface of lamp housing 1, the great power LED light emitting diode 3 of at least one above quantity passes the punching of circuit board 4, directly be mounted on the inner surface of lamp housing 1, and LED just, negative the two poles of the earth then are welded on the circuit board 4, obviously, as long as adopt suitable packaging technology and sealed in unit frock, also light-emitting diode chip for backlight unit directly can be encapsulated in the inner surface of lamp housing 1, its heat conductivility can be better.Illustrate glass plate or lens 5 among the figure; its effect is close and protect LED element and appears light; the two ends of lamp housing 1 can be sealed with end cap 6; power lead can pass end cap and insert on the lamp interior circuit board; and the power supply module module of driving LED can place the outer power source special box of light fixture, the end cap box of the power module that also end cap 6 can be designed to pack into.

From accompanying drawing, can see intuitively, the heat energy that led chip produces passes to the outer moving air of lamp with very short path, can just can not make the LED temperature rise too high by in time quick distribute heat, thereby slow down the light decay process of LED, reach the purpose that prolongs the LED working life, this is the advantage place of the utility model light fixture.

Claims (2)

1, a kind of LED lamp, comprise LED light-emitting component, lamp housing, it is characterized in that: lamp housing is made by aluminium matter or aluminium alloy extrusions, and the outer surface design of this aluminium section lamp housing has some radiating fins, and the LED light-emitting component directly is mounted on the inner surface of this aluminium section lamp housing.

2, LED lamp according to claim 1 is characterized in that: said LED light-emitting component is packaged great power LED light emitting diode.
