Problems solved by technology

In addition, the driving power and the LED light board are separated. In the application of large-scale chandeliers (requiring many light bulbs), the connection work of many driving power is very heavy, and if one of the light bulbs is broken, it needs to be judged to be an LED light. If the board is broken or the power supply driving the LED light board is broken, the actual operation is almost impossible, and all the bulbs can only be replaced. , or can only choose to change the lamp as a whole

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...

Abstract

The invention relates to a driving-free energy saving bulb comprising a radiator, a circuit module and an LED lamp panel. The LED lamp panel is mounted on the radiator. The driving-free energy savingbulb is characterized in that the circuit module comprises a piezoresistor, a bridge rectifier, a chip resistor and an LED module which are mounted on the LED lamp panel and electrically connected insequence; the LED module comprises a plurality of light-emitting chips which are connected in parallel; and the radiator is provided with a lamp holder assembly used for making the circuit module to be electrically connected with a mains supply. The driving-free energy saving bulb has the advantages that not only are the light source and the personal safety of users only protected, but also various decorative effects can further be achieved according to matched multi-modeling lampshades.

Description

technical field [0001] The invention relates to a driver-free energy-saving light bulb. Background technique [0002] Existing light bulbs generally include a heat sink, a driving power supply and an LED light board. The LED light board is installed on the heat sink, and the driving power supplies power for the LED light board. Compared with the LED light board, the driving power is often larger and heavier. It is heavy, so there needs to be enough space for the plug driver. In addition, the driving power and the LED light board are separated. In the application of large-scale chandeliers (requiring many light bulbs), the connection work of many driving power is very heavy, and if one of the light bulbs is broken, it needs to be judged to be an LED light. If the board is broken or the power supply driving the LED light board is broken, the actual operation is almost impossible, and all the bulbs can only be replaced. , or can only choose to change the lamp as a whole.
