A LED wall washer light comprising front housing, rear housing, light pole fixation base, clear cap, characterized in that: it also comprises the transformer fixed on the rear housing and the LED panel connected with the front housing; there are couples of heat sinks on external surface of the rear housing; the internal surface of the foresaid front housing is equipped with minimum one slot with couples of heat sinks in; on internal surface of the foresaid front housing, there is minimum one slot corresponding to the slot equipped on the foresaid front housing internal surface; the foresaid slot is arch in shape.
In many instances the intended effect of the wall washer light is to combine with an architectural feature so that the combination of the light and the feature is impressive, eye-catching, or artistically attractive. The lights are typically located in such way that their effect is seen but not their location so as to augment the aesthetics of their use. Incandescent and fluorescent lights have typically been used in these applications because they provide the necessary amounts of illumination capable of brightly lighting a large area. However, high intensity LEDs have recently become preferable to replace the incandescent or fluorescent lights because of LEDs adequate light output and lower power consumption.
Applying the principle of aluminum alloy conduction for heat elimination, the existing LED wall washer light are troubled with the following shortcomings: when the metal of copper or aluminum alloy is used for connecting the LED light panel with ballast, heat sinks of the LED and ballast will lower the temperature of the LED light and the ballast. In case of more than 32 LED lights, this kind of heat elimination can not effectively conduct the temperature from LED and ballast to the air That causes a temperature in the integrated light box over 70° C. When the LED wall washer lights are integrated together with surface sealed and temperature goes high, the LED will be in fast degradation until it goes out.
For achieving the objective above, this invention adopts the following technical scheme: A LED wall washer light comprising front housing, rear housing, light pole fixation base, clear cap, characterized in that: it also comprises the transformer fixed on the rear housing and the LED panel connected with the front housing; there are couples of heat sinks on external surface of the rear housing; the internal surface of the foresaid front housing is equipped with minimum one slot with couples of heat sinks in; on internal surface of the foresaid front housing, there is minimum one slot corresponding to the slot equipped on the foresaid front housing internal surface; the foresaid slot is arch in shape. Couples of heat sinks are equipped in slot on internal surface of the front housing.
The heat sinks are designed for conducting heat from the LED wall washer light panel to the air for timely eliminating heat from the LED. In practice, there are couples of corresponding slots with arch section on the surface at which the front panel and the rear panel contacts, and their lengths are the same as that of the front panel and rear panel respectively. Therefore, when the front panel combines with the rear panel, couples of through-holes are formed. There are couples of heat sinks equipped in the each arch slot in the front housing. By this way, the heat of LED light panel is timely eliminated.
