Abstract

The invention discloses a rotary LED lamp. The rotary LED lamp comprises a lamp holder, a shell, a power source, a motor, a heat dissipation device, a circuit board, LEDs and a connecting ring. The power source is arranged in the lamp holder. The shell is arranged below the lamp holder. The motor is coaxially arranged on the central axis of the lamp holder. The connecting ring is coaxially arranged at the upper end of the heat dissipation device. The heat dissipation device is connected to the lower end of the motor. The circuit board is designed on the heat dissipation device. The LEDs are attached to the circuit board. In this way, the rotary LED lamp has the advantages that the reliability is high, the structure is compact, the heat dissipation performance is good, electric conduction is stable, cost is low, and the service life is long. In addition, the rotary LED lamp has wide market prospect on the illumination market.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a 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 leads to excessively high junction temperature of the LED, resulting in serious light decay and affecting the service life. The existing rotating LED lamps cannot achieve good heat dissipation of the LEDs only...
