Abstract
The invention provides a light-emitting diode (LED) bulb and an LED street lamp. When the LED bulb is used, the LED bulb is connected onto a lamp holder through a connector, further direct-current voltage is input, and a plurality of LEDs arranged on an LED lamp panel begin to emit light. Simultaneously, due to the fact that an electric fan is connected between the connector and the LED lamp panel in series, the electric fan also starts to run, namely the electric fan does not need to be powered on separately. Due to the fact that a rectifying bridge is connected with the inner portion of the bulb, the whole LED bulb is non-polarized and only needs to be powered on through a screw socket. Due to the fact that a 5mm gap between a casing and a glass plate increases ventilation channels on the front sides of the LEDs, volume of the LED street lamp is reduced. Circuit complexity and installation complexity are reduced, and cost is saved.
