Abstract

The invention discloses a lamp cup with an adjustable lighting range, which includes a cup body and an LED light source, and is characterized in that it also includes a lampshade, the cup body is hemispherical, and a lampshade is arranged symmetrically at the upper and lower ends of the cup body. The lampshade is a quarter spherical cover body, the outer diameter of the lampshade is equal to the inner diameter of the cup body, the outer surface of the lampshade located on one side of the cup body is set close to the inner wall of the cup body, and the two ends of the lampshade are fixed on the cup body through rotating shafts. The invention provides an LED lamp cup capable of adjusting the lighting range. By rotating the lampshade, part of the light from the light source is shielded, so as to achieve the effect of adjusting the lighting range. The invention has a simple structure, is easy to operate, and is convenient and practical.

Description

technical field [0001] The invention relates to a lamp, in particular to a lamp cup capable of adjusting the lighting range. [0002] Background technique [0003] Most of the fixedly installed lamps have a fixed lighting range, and some special types of lamps, such as desk lamps, can only adjust their lighting range by moving the position of the lamp or adjusting the bracket supporting the lamp head. However, it is very inconvenient to move the position of the lamp, and often adjust the height and angle of the lamp holder, which will easily cause wear and tear on the device. When the wire is installed inside the bracket, it will easily cause damage to the circuit. Contents of the invention [0004] In order to solve the problems in the prior art, the present invention provides a lamp cup with an adjustable lighting range. [0005] The technical solution of the present invention is a lamp cup with an adjustable lighting range, which includes a cup body and an LED light s...
