A kind of SLR rotary control LED lamp

Abstract

The invention relates to a single lens reflex rotary control type LED lamp. The single lens reflex rotary control type LED lamp comprises a transparent lamp plate shell, the interior of the transparent lamp plate shell is of a cavity structure, an adjusting pipe is arranged on the upper portion of the transparent lamp plate shell, a guide shaft is sleeved with the adjusting pipe, and the guide shaft is sleeved with limiting rings; abut-joint rods are arranged on the guide shaft, fixing pieces are arranged at the upper ends of the abut-joint rods, fixing bolts are arranged on the fixing pieces, limiting pieces are arranged on the inner side walls of the ends of the abut-joint rods, magnet blocks are arranged on the limiting pieces, and an abut-joint strip is arranged between the limiting pieces; magnetic attraction pieces are arranged on the lower portion of the transparent lamp plate shell, and correspond to the magnet blocks; a circuit control board is arranged in the transparent lamp plate shell, and a plurality of LED lamps are arranged on the circuit control board; and thin-film batteries are arranged on one side of the transparent lamp plate shell, and are connected with the control circuit board through connecting lines. The transparent lamp plate shell can be adjusted to the position between the abut-joint rods, the transparent lamp plate shell is rotatably mounted between the abut-joint rods through the limiting pieces, and therefore flexible adjusting of the transparent lamp plate shell is facilitated, and lighting of the LED lamps is facilitated.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a single-reverse rotary control LED lamp. Background technique [0002] LED is a solid-state semiconductor device that can convert electrical energy into visible light, and 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, one end is the negative pole, and the other end is connected to the The positive pole of the power supply makes the whole chip encapsulated by epoxy resin. Semiconductor wafer is made up of two parts, and a part is P-type semiconductor, and hole occupies an leading position in it, and the other end is N-type semiconductor, and here mainly is electron. But time these two kinds of semiconductors couple together, between them, just form a P-N junction. When electric current acts on this chip by wire time, electron will be pushed to P district, and in P district, electron is recombined with ho...
