Embodiment Construction
[0016] refer to Figure 1-Figure 2 Generally, the light source and the driving module 23 of the traditional lamps are set separately, which takes up a lot of space. A dimmable driver-free LED lamp circuit according to the present invention includes a dimming module 1 and a light source circuit board 2, and the driving module 23 It is integrated with the light source on the same light source circuit board 2, and the driver IC of the drive module 23 provides a stable working voltage for the LED module 21, which can provide a stable working voltage for the LED lamp. At the same time, the light source circuit board 2 is placed on the original LED The location of the lamp reduces unnecessary space design, and the light source circuit board 2 is also provided with a power input terminal 22, a conversion circuit 24, a protection circuit 25, etc., and the light source circuit board 2 is connected to the power grid through the power input terminal 22 , and then convert the alternating ...
