Arc-shaped rotary LED lamp

Abstract

The invention discloses an arc-shaped rotary LED lamp which comprises a lamp holder, a power supply, a motor, a heat radiator and an LED. The power supply is arranged in the lamp holder, the motor is arranged below the power supply, a conductive ring is arranged below the motor, the heat radiator is arranged on a motor shaft, and the LED is arranged on the heat radiator. Through the mode, the arc-shaped rotary LED lamp has the advantages of being high in reliability, compact in structure, free of flashing, low in noise, low in price, low in operating temperature, long in service life, good in illumination and the like, and meanwhile has wide market prospects in the LED illumination market.

Description

technical field [0001] The invention relates to the field of lighting, in particular to an arc-shaped rotating LED lamp. Background technique [0002] LED is a light-emitting diode, which is a new type of light source. It has low power consumption, long life, small size, high brightness, low energy consumption, and no pollution. It is known as the green lighting source in the 21st century. , cannot have good astigmatism characteristics like ordinary incandescent lamps and fluorescent lamps, and often have problems such as small lighting range, large brightness difference between the irradiated area and the non-irradiated area, and at the same time, due to the small size of the luminous body, the heat is concentrated, and the heat dissipation of the package is not good. , often lead to high LED junction temperature, resulting in serious light decay and affecting the service life. At the same time, the existing rotating LED lighting characteristics are not good, there is a cer...

[0002] LED is a light-emitting diode, which is a new type of light source. It has low power consumption, long life, small size, high brightness, low energy consumption, and no pollution. It is known as the green lighting source in the 21st century. , cannot have good astigmatism characteristics like ordinary incandescent lamps and fluorescent lamps, and often have problems such as small lighting range, large brightness difference between the irradiated area and the non-irradiated area, and at the same time, due to the small size of the luminous body, the heat is concentrated, and the heat dissipation of the package is not good. , often lead to high LED junction temperature, resulting in serious light decay and affecting the service life. At the same time, the existing rotating LED lighting characteristics are not good, there is a certain lighting blind area, and because the radiator is connected to the LED, the overall structure is heavy, making the rotating Decreased structural life
