A LED source module includes a light-transmitting shade (1), a lamp cup (2), a plurality of LED sources (3), a sealing member (4), a flexible circuit board (5) and a radiating block (61). Each LED source (3) is electrically connected with the flexible circuit board (5). The light-transmitting shade (1) is mounted at the lower portion of the lamp cup (2). Holding holes whose number and positions correspond to the number and mounting positions of the LED sources (3) are arranged on the flexible circuit board (5). The flexible circuit board (5) is affixed at the inner side of the radiating block (61). Each LED source (3) is directly welded on the surface of the inner side of the radiating block (61) through one holding hole of the flexible circuit board (5). Through holes whose number and positions correspond to the number and mounting positions of the LED sources (3) are arranged at the top of the lamp cup (2). The lamp cup (2) is fixed at the lower portion of the radiating block (61), making each LED source (3) mounted on the radiating block (61) pass through the corresponding through hole and enter the inside of the lamp cup (2). Sealing is carried out using the sealing member (4), thus forming a closed cavity among the light-transmitting shade (1), the lamp cup (2) and the LED sources (3). |
