Abstract
The disclosure is related to a light-emitting device for lamp, including a circuit board and a patch LED lamp. The circuit board is provided with an LED driving chip and a plurality of resistor elements. The circuit board is provided with a pad corresponding to the patch LED lamp. The patch LED lamp includes a light-emitting substrate and two connecting legs connecting the light-emitting substrate. The connecting legs are formed in L shape and are respectively connected to two opposite sides of the light-emitting substrate. The connecting legs of the patch LED lamp are soldered on the pad, and an angle between the light-emitting surface of the patch LED lamp and the pad is 90°.
