Lighting device

Abstract

The invention discloses a lighting device comprising a control circuit, an LED lamp, a first power supply, a second power supply and a sensor. The control circuit is electrically connected with the LED lamp, the first power supply, the second power supply and the sensor. The first power supply is an external power supply. The second power supply is a rechargeable lithium battery. The sensor is used for sensing whether the light is bright or dark and feeding the sensing result back to the control circuit, and the control circuit controls the LED lamp. The lighting device is suitable for lighting in a variety of working or living environments. Even if the power fails, there is a standby power supply to provide electric energy.

Description

Technical field [0001] The invention belongs to the field of lighting, and particularly relates to a lighting device. Background technique [0002] Energy-saving desk lamps are widely used due to their advantages of low power consumption, power storage, and small size, and are especially suitable for students' learning. However, the general energy-saving lamp has a single function, especially in terms of power supply, which does not solve the problem of normal operation of the LED lamp during a power failure. Summary of the invention [0003] In order to solve the above technical problems, the purpose of the present invention is to provide a lighting device. The technical solutions adopted by the present invention are as follows. [0004] A lighting device, including a control circuit, an LED lamp, a first power supply, a second power supply, and a sensor; [0005] The control circuit is electrically connected to the LED lamp, the first power supply, the second power supply, and the...
