Problems solved by technology

In this patented product, its rotation angle is small, and it cannot realize all-round adjustment, so it has a certain blind area in application.
Moreover, the clamping position of the lamp cap of this patent is connected with the clamping groove of the lamp cap, and the two cannot be effectively fixed, and loosening may occur during use, causing inconvenience to daily use.

Abstract

The invention provides a rotatably positioned LED lamp, belonging to the field of illumination devices, solving the problems that the existing LED lamp cannot rotate easily and the positioning accuracy is not high. The rotatably positioned LED lamp comprises a lamp holder, an LED lamp body and a rotatably positioning mechanism arranged between the lamp holder and the LED lamp body, and is characterized in that the rotatably positioning mechanism comprises a fixed ring connected with the lamp holder, a rotary disc connected with the LED lamp body and a positioning assembly, the rotary disc andthe fixed ring can rotate relatively and the LED lamp can be rotatably positioned through the positioning assembly. Since the rotatably positioning mechanism is arranged between the lamp holder and the LED lamp body, the goal of adjusting the illumination direction of the LED lamp is realized. The invention has the advantages of simple structure, accurate positioning and convenient adjustment anduse.

Description

technical field [0001] The invention belongs to the field of lighting equipment, and relates to a lamp, in particular to a rotatably positioned LED lamp. Background technique [0002] LED technology is widely used. When LED lamps are used, they have the characteristics of low power consumption and soft light. The main structure is: install the LED chip on the chip substrate, the back of the chip substrate is connected The power cord in the heat sink is connected to the junction point on the lamp head. After the lamp head is plugged into the power supply, the lamp can emit light. LED lamps in the prior art can only emit light in a specific direction because the back of the chip substrate is connected to the heat sink, so it is necessary to face the side with the LED chip in the direction to be illuminated during installation, but there are Sometimes, due to the setting of the lamp holder or the power plug of the lamp, the above-mentioned LED chip, that is, the irradiating su...
