Embodiment 1

[0015] Embodiment one: as attached figure 1 As shown in the LED lamp that can be automatically dimmed, the lamp holder 1 is in the shape of a cylinder, and an elongated receiving groove is opened on the end face of the lamp holder 1, and a rotatable lamp is installed between the two groove walls of the receiving groove. A shaft, on which a ring-shaped lamp body 2 is fixed, the lamp body 2 can rotate under the drive of the lamp shaft, and the outer circle of the lamp body 2 is tangent to the groove wall of the receiving groove. In this embodiment, three mounting grooves are provided on the lamp body 2 along the half circumference of the lamp body 2, and an LED lamp cap is arranged in each mounting groove, and the outer circle formed by each LED lamp cap is on the same circle as the outer circle of the lamp body 2 , and each LED lamp holder is threadedly connected with the installation groove for easy disassembly. Such as figure 1 As shown, the exposed LED lamp holders in this...

Embodiment 2

[0020] Embodiment two: the difference between this embodiment and embodiment one is that a relay is also provided between the collector of the second transistor and the negative pole of the second light-emitting diode, and the normally open contact of the relay is connected to an electromagnet. On the circuit, iron bars are arranged on the lamp body, and when the electromagnet is energized, the iron bars can be attracted to force the lamp shaft to rotate.

Abstract

The invention discloses an LED lamp capable of automatically adjusting brightness, so as to solve problems that an LED lamp in the prior art cannot adjust the brightness according to the illuminance and a lamp which is not in use is exposed outside and is liable to be polluted. The LED lamp comprises a lamp seat, and the lamp seat is provided with a storage groove. A rotatable lamp shaft is disposed between two wall of the storage groove, and is fixedly provided with an annular lamp body. The half periphery of the lamp body is provided with a plurality of installation grooves, and the interior of each installation groove is provided with one LED lamp cap. An outer circle formed by all LED lamp caps and the outer circle of the lamp body are located in the same circumference. All LED lamp caps are controlled by one light adjustment circuit. When the environment light is suitable for reading and writing, a part of LED lamp caps are covered by the lamp seat. When the environment light is weaker, the light adjustment circuit controls the lamp shaft to rotate, and the part of the LED lamp caps are exposed, and are turned on at the same time.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an LED lamp capable of automatic dimming. Background technique [0002] LED, also known as light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. With the advancement of technology and the continuous improvement of people's living standards, LED lights have been widely used in our daily lives. It has changed the traditional lighting method to a great extent. LED lights have the advantages of good heat dissipation, long service life and energy saving. However, with the improvement of people's quality of life, people also put forward higher requirements for lighting functions. The disadvantages are: 1. The illuminance cannot be adjusted according to the intensity of the ambient light, so the protection effect on people's eyesight is poor; 2. In addition, when multiple LED lights are installed in the home, such as multiple L...
