Adjustable LED (light-emitting diode) illumination lamp

Abstract

The invention relates to the technical field of LED (light-emitting diode) light sources, and discloses an adjustable LED illumination lamp. The adjustable LED illumination lamp comprises a base, wherein four universal wheels uniformly distributed are fixedly connected with the bottom of the base; a sliding groove is formed in the front surface of the base; a positioning groove is formed in the bottom surface of the sliding groove; three sliding blocks uniformly distributed are connected into the sliding groove in a sliding manner; the front surface of one of the three sliding blocks is movably connected with a fixed screw; and a bearing plate is fixedly connected with the tops of the three sliding blocks. When the adjustable LED illumination lamp is in use, the fixed screw is unscrewed; when the bearing plate rotates, the bearing plate can drive a casing and an adjustment rod on the bearing plate to rotate synchronously; a mounting plate and an LED lamp holder fixedly connected with the mounting plate can be driven by a hinge seat to rotate synchronously; when the LED lamp holder rotates to a corresponding position, the fixed screw is tightened to be contacted with the interior ofthe positioning groove; sliding of the sliding blocks can be limited by a friction force; and when the positions of the sliding blocks are fixed, and the sliding blocks cannot move, an illuminating direction of the LED lamp holder can be determined.

Description

technical field [0001] The invention relates to the technical field of LED light sources, in particular to an adjustable LED lighting lamp. Background technique [0002] LED, also known as light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor chip. One end of the chip is attached to a bracket. It is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin. [0003] With the development and application of new materials in recent years, LEDs have been widely used in life and industrial production due to their excellent performance. Among them, lighting equipment using LEDs as light sources is particularly common in production and life, but the existing LED lighting The equipment generally has the problem that it cannot be adjusted and cannot...
