An LED integrative structure with cooling device comprises a heat-radiating substrate (3), an LED chip (4), a lens (5), a lens locator (6) and a cooling device. The lens locator (6) is provided with a first hole (15), and also with a fixing column (16) extending from the end surface of the lens locator. The fixing column (16) passes through a second hole (21) on the heat-radiating substrate (3), and is fixed with the heat-radiating substrate (3) through the block part (17) located on the end of the fixing column (16); the LED chip (4) is fixed directly on the heat-radiating substrate (3) through solid crystal technique, and is located in the first hole (15); the cooling device is provided on the side of the heat-radiating substrate (3) which is opposite from the LED chip (4), and may be cooling medium, fan and/or the refrigeration device. The structure has the advantages of the precise position relationship between the lens and the chip, simple assembly, reduced heat resistance of intermediate portion and good radiating effect. |
