Abstract

The invention provides an LED down lamp which comprises a panel outer ring, a pressure spring, a panel inner ring, a lens, a luminous source, a radiating device and a fixed cover. The panel outer ring is provided with a shaft hole and a clamp. The panel inner ring provided with a rotary shaft is mounted on the panel outer ring. The rotary shaft is fixed in the shaft hole. One end, close to the rotary shaft, of the panel inner ring is pressed into the clamp. One end of the pressure spring is fixed on the clamp. The other end of the pressure spring is pivoted with the rotary shaft. The luminous source is fixed on the lens fixed on the panel inner ring. The radiating device provided with clamp hooks at two ends is fixed above the luminous source. The panel inner ring is movably connected to the panel outer ring, so that the panel inner ring can rotate relative to the panel outer ring, is less prone to looseness, and is low in manufacturing cost. Accordingly, light emitting angle is adjustable, and a user can conveniently adjust the light emitting angle by controlling the pressure spring only.

Description

technical field [0001] The invention relates to LED lighting equipment, in particular to an LED downlight. Background technique [0002] Light Emitting Diode (LED, Light Emitting Diode) is a PN-type semiconductor diode that uses current to emit light. When a forward voltage is applied, electrons flow into the P-type semiconductor, holes enter the N-type semiconductor, and electrons and holes recombine to emit light. The light-emitting tube made by using this principle is a light-emitting diode, and high-power LED lighting fixtures are made of high-power light-emitting diodes. With the development of science and technology, LED lamps are gradually replacing traditional incandescent lamps due to their advantages of small size, high brightness and energy saving. [0003] In the existing LED downlights, the heat dissipation part is cut and processed by aluminum profiles, and the heat dissipation device part and the inner ring of the panel are installed by thread rotation. When ...
