Description

Down lamp adjusting structure Technical Field The utility model relates to a lamp, in particular to a direction adjusting structure on a down lamp. Background Down lamps are commonly used lamps in modern decorations, which are installed in a ceiling by embedding and project light in a specific direction, for example, on a font of a wall, a decorative painting, thereby forming a desired atmosphere effect. In order to ensure the irradiation direction of the down lamp, the user needs to detach the down lamp, then rotate the reflection cup for guiding light, and then reinstall the down lamp to the ceiling, if the irradiation direction is still not ideal, the direction of the down lamp needs to be repeatedly assembled and disassembled and adjusted, so that the whole operation process is very troublesome, and the working efficiency is low. Disclosure of utility model The utility model aims to provide a down lamp adjusting structure capable of adjusting the irradiation direction without disassembly, so that the convenience of adjustment is reduced, and the construction efficiency is improved. The utility model relates to a down lamp adjusting structure, which comprises a base, a lamp holder, an LED lamp bead, an adjusting ring, a rotary drum, a light guide cup and a light guide cup, wherein the base is annularly arranged, the lamp holder is hollow in the inside and is provided with an opening at the bottom, the bottom of the lamp holder is arranged on the base and is connected with a light reflecting cup, the top of the inner side of the lamp holder is provided with the LED lamp bead, the rotary drum is further arranged in the lamp holder, one end of the rotary drum is connected with the inner wall of the adjusting ring, the shape of the inner wall of the adjusting ring and the outer wall of the end part of the rotary drum is in a matched spherical shape, the rotary drum is also provided with the light guide cup capable of transmitting light, and two ends of the light guide cup are respectively arranged opposite to the LED lamp bead and the light reflecting cup.
