Light emitting diode (LED) lamp with adjustable irradiation angles

Abstract

The invention discloses a light emitting diode (LED) lamp with adjustable irradiation angles. The LED lamp comprises a power line, a driving circuit module, a supporting frame, a snap spring, a lamp body and a lamp holder, wherein the power line and the driving circuit module are arranged on the supporting frame and are connected, the driving circuit module is connected with the lamp body, the lamp body is connected with the lamp holder, the lamp body comprises a lamp casing, a lamp cover, a reflecting shade and an LED irradiation module, the lamp casing and the lamp cover are assembled to form a first cavity, the reflecting shade is arranged inside the first cavity, the LED irradiation module is arranged on the reflecting shade, the reflecting shade is covered by a transmitting filter, the supporting frame is arranged on the lamp holder, the lamp body is hung on the lamp holder thorough the snap spring, two sides of the lamp body are provided with column-shaped bumps, two sides of the lamp holder are provided with semicircular grooves, the column-shaped bumps and the semicircular grooves are matched, and the matching portions of the column-shaped bumps and the semicircular grooves are pressed by pressing blocks. The lamp body rotates, then the LED irradiation module is driven to rotate, irradiation angles are changed, the problem of the irradiation angles of the LED lamp is effectively solved.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to an LED lamp with an adjustable irradiation angle. Background technique [0002] LED (Lighting Emitting Diode) is a light-emitting diode, which is a semiconductor fixed light-emitting device. It uses a solid semiconductor chip as a light-emitting material, and releases energy through the recombination of carriers in the semiconductor. The energy is emitted in the form of photons, thereby emitting light. , LED lighting fixtures use LEDs as light sources. In the context of the current global energy shortage, energy-saving LEDs have attracted people's attention. [0003] As people's requirements for green lighting are getting higher and higher, LED lighting with many advantages such as low energy consumption, high luminous efficiency, and long service life has gradually replaced traditional fluorescent tubes and halogen lamps, and has begun to be widely used. At present, the existing lighting ...
