Bedside energy-saving induction lamp

Abstract

The invention discloses a bedside energy-saving induction lamp which comprises an induction device, a photosensor, a control circuit module and a light source; the induction device comprises a pressure induction device and an infrared induction device; the pressure induction device controls the on and off of the light source according to induction signals generated by the pressure on a bed; the infrared induction device controls the brightness of the light source according to induction signals caused by fact that whether a person moves around or not in a certain range; the control circuit module comprises a signal receiving and processing circuit, a brightness adjusting circuit, a delay circuit and a brightness setting circuit; one end of the light source is connected to the brightness adjusting circuit, and the other end is connected to the brightness setting circuit; and the photosensor is connected between the induction device and the signal receiving and processing circuit. Through the above manner, the induction lamp can realize auxiliary lighting and main lighting through only one light source and can set the initial brightness of the light source; besides, the illumination intensity of the ambient light is detected through the photosensor, and the lamp is turned off in daytime and turned on at night, so that the effect of saving energy can be really achieved.

Description

technical field [0001] The invention relates to an induction lamp, in particular to an energy-saving induction lamp specially used in front of a bed, which can be automatically turned on and off by pressure induction and can have a certain auxiliary brightness. Background technique [0002] In modern homes, there must be a lighting fixture in front of the bed for lighting when starting at night. Currently on the market, most of these lighting fixtures are table lamps or floor lamps, and a few of them are infrared sensor lights. [0003] There are generally two types of traditional pyroelectric human body induction lamps. One type of induction lamp has only one light source. When someone moves or approaches, the lamp lights up. After the person leaves, the lamp will automatically turn off after a certain time delay. Another induction lamp contains two light sources, the main light source and the auxiliary light source. If there is no activity in the sensing area, the auxilia...

AI Technical Summary

Problems solved by technology

The luminous efficiency of incandescent lamps and tungsten halogen lamps is generally 10lm / W, which is far lower than the 70lm / W of energy-saving lamps, so traditional induction lamps are not energy-saving and environmentally friendly.

In addition, even in the daytime, the traditional pyroelectric sensor light will be turned on if it senses the approach of the human body, resulting in ineffective power consumption and wasting electric energy
