Abstract
The invention discloses an LED bulb capable of dissipating heat actively. The LED bulb capable of dissipating heat actively comprises a screwed connector, a fixed base and an LED lampwick. A reducing cylinder is connected to the bottom of the fixed base. A circuit board connected with the LED lampwick is arranged in the fixed base. An air inlet is formed in one side of the cylinder. An air outlet is formed in the other side of the cylinder. A filter screen is arranged at the position of the air inlet. A draught fan is arranged on the inner side of the air outlet. A temperature control switch is connected to the circuit board and is connected with an input circuit of the draught fan. In this way, the LED bulb capable of dissipating heat actively has the advantages that the circuit of the draught fan is closed through the temperature control switch when the temperature of the circuit board exceeds a limit value, so that forcible ventilation and heat dissipation are conducted, the internal working environment is improved, the service life of the circuit board and the service life of the LED lampwick are prolonged, and the LED bulb capable of dissipating heat actively is suitable for long-term work.
