Description

The LED module

[technical field]

The utility model relates to a kind of LED module, particularly a kind of LED module with excellent heat dispersion performance and water resistance.

[background technology]

Be seen everywhere in our daily life of illuminations worker, family, the sub-district, road and tunnel all are provided with a lot of light fixtures; Especially the light fixture in road and the tunnel, traditional light fixture has incandescent lamp, high-pressure mercury lamp, light fixtures such as metal halide lamp; Adopt the occasion of high-pressure mercury lamp many, but because the expensive of these light fixtures, and will light for a long time, the electric energy of consumption is very big; Sometimes also can produce stroboscopic, phenomenon such as gradually bright is just in case breakage also pollutes the environment, therefore in recent years; Because the LED lamp is luminous very stable, there are not stroboscopic and phenomenon such as gradually bright, power consumption is few, and the life-span such as grows at reason; The LED lamp has replaced other light fixture just gradually, is widely used in road, and tunnel etc. need the occasion of long-term illumination.

But there is a hidden danger in present LED lamp, because road and tunnel light fixture need long-time the unlatching; And quantity is more, just needs the large power supply power supply, will cause product temperature too high like this; In the open or in the tunnel, LED etc. probably are soaked with rain, soaked by moisture; The LED of poor sealing burns out easily, is easy to cause the situation of short circuit, has reduced the service life of LED lamp.In addition; Traditional LED light fixture generally need be equipped with a very big radiator; The radiator of at present common on the market LED light fixture comprises the heat radiation lamellar body with lattice-shaped fin, on the heat radiation lamellar body, aluminium base is installed, and is the PCB that LED is installed on the aluminium base.The LED light fixture of said structure, the increase and decrease of the power of LED lamp and the area of dissipation of radiator is consistent basically, can cause needs to be equipped with a bigger radiator if therefore increase the power of LED light fixture, can cause cost obviously to increase like this.At present; The radiating efficiency of shaping lamp radiator is not very desirable, in order to obtain better radiating effect, when increasing radiator, can increase product weight simultaneously yet; Because most of light fixtures all are used for eminence; Overweight LED light fixture not only increases cost, has also increased the risk in mounting hardness and the use simultaneously, falls the risk that causes like the high-altitude.

In addition, traditional LED module generally is made up of the LED module of an integral body, in the LED module LED that matrix is arranged is arranged into; Such structure is for the maintenance of light fixture; A LED has broken down, and needs to change the whole LED module, and the LED matrix in the module all has been wasted.Therefore, maintenance cost height very.

So gesture is driven in the development that present module type LED will become following LED light fixture.
