Embodiment Construction
[0020] as attached figure 1 to attach Figure 5 As shown, the driver-free energy-saving light bulb includes a radiator 1, a circuit module and an LED lamp board 2, the LED lamp board 2 is installed on the radiator 1, and the circuit module includes a varistor installed on the LED lamp board 2 and electrically connected in sequence, A bridge rectifier, a chip resistor and an LED module. The LED module includes several light-emitting chips 21 and is connected in parallel. By sequentially electrically connecting the varistor, the bridge rectifier, the chip resistor and the LED module, the circuit module can be The mains power is converted into a voltage and current suitable for the LED chip to emit light, so that the LED chip 21 can normally emit light.
[0021] The radiator 1 is provided with a lamp cap assembly 3 for electrically connecting the circuit module with the mains. The lamp cap assembly 3 includes a lamp cap shell 31 and a first connecting piece 321 and a second con...
