Abstract

The invention discloses a down lamp which comprises an inner ring, a rotary ring, an outer ring, a lamp plate arranged in the inner ring, LED chips and light-transmission diffusion plates. The front and the back of the inner ring are separately connected with the diffusion plates. The front and the back of the lamp plate are separately provided with the LED chips which are located in an accommodation cavity formed by the diffusion plates, the inner ring and the lamp plate. The inner ring, the rotary ring and the outer ring are coaxially matched. The rotary ring is arranged between the inner ring and the outer ring. The inner ring and the rotary ring are movably connected to enable the inner ring to swing around the joint. The rotary ring and the outer ring are in clamped connection to enable the rotary ring to rotate around the center axis Z. According to the down lamp adopting the structure, the illumination range of LED light sources is widened by combining the rotary ring which can rotate by 360 degrees and the structure that an existing inner ring can swing in a certain angle range, and the down lamp is simple in structure and convenient and fast to manufacture and assemble.

Description

technical field [0001] The present invention relates to the technical field of LED lighting (LED: Light Emitting Diode, light emitting diode), in particular to a downlight. Background technique [0002] LED is a semiconductor solid light-emitting device. It uses a solid semiconductor chip as a light-emitting material. When a forward voltage is applied to both ends, the carriers in the semiconductor recombine to cause photon emission to generate light. Downlight is a new type of home lighting product. LED downlight uses LED as the light source. Compared with traditional downlights in the past, it has the following advantages: high efficiency, energy saving, long life, and good color rendering. But the current LED downlight has the following disadvantages: [0003] 1. In the traditional LED ceiling lamp, the inner ring of the light frame is connected to the outer ring by two screws. The screws are set in the radial direction of the inner ring, and the inner ring can wrap arou...
