Illuminating array of high-power light-emitting diode

The present utility model relates to a high power LED array lighting device with good heat dispersion, characterized in that several individual LEDs are directly placed on a metal cooling plate of large area in the form of metal base plate to form a lighting array so that the heat arising from the lamp array bank disperses fast. This greatly improves the LED's heat dispersing efficiency, meets the requirement for temperature limit set for the high power LED chip and ensures the service life and efficiency. Applying heat-conducting silicone grease between the base plates of the individual LEDs and the metal cooling plate of large area and additional supporting cooling means on the cooling plate will further increase the heat dispersing effect. So, dozens or even a hundred of high power LEDs can be used to form a highly integrated lighting array to produce a luminaire with thousands of lumens for practical lighting application as in the case of street lights.
