Embodiment Construction
[0027] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] see Figure 1-2 , figure 1 It is a schematic structural diagram of an LED light bulb provided by an embodiment of the present invention, figure 2 It is the schematic circuit diagram of the LED light bulb provided by the embodiment of the present invention.
[0029] As shown in the figure, the LED light bulb in this embodiment includes: a casing 10 , an electric fan 20 and a joint 30 protruding from the side wall of the casing 10 . Wherein, the connector 30 is used for inputting DC voltage when the LED bulb is connected to the lamp socket. The front of the housing 10 is provided with an LED lamp board 11, and the LED lamp board is provided with several LEDs. The electric fan 20 is connected in series between the joint 30 and the LED lamp board 11. The electric fan 20 After being connected in series with the...

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.
Description
technical field [0001] The invention relates to the technical field of lighting, in particular to an LED light bulb and an LED street lamp. Background technique [0002] Street lamps are an important part of urban lighting. Traditional street lamps often use high-pressure sodium lamps or high-pressure mercury lamps. High-pressure sodium lamps or high-pressure mercury lamps have high energy consumption and low luminous efficiency. Light-emitting diode (Lighting Emitting Diode, LED) street lights have gradually entered people's field of vision with the advantages of directional light emission, fast response, high shock resistance, long service life, and environmental protection, and have become the world's most powerful new generation of energy-saving alternatives to traditional light sources. light source. [0003] An LED street light is provided in the prior art, which includes: an LED street light source and joints respectively sleeved on both ends of the LED street light ...
