Novel intelligent energy-saving long-life and human body induction type light-emitting diode (LED) lamp

Abstract

The invention provides a novel intelligent energy-saving long-life and human body induction type light-emitting diode (LED) lamp, which is characterized by comprising a power supply module, a power supply and voltage conversion module, a control module and an LED light source module. The control module comprises a central processing unit (CPU), a detector in circuit connection and signal connection with the CPU and a photoreceptor. The power supply module is the main power supply of the whole lamp and converts mains supply alternating current to direct current supplied to the power supply and voltage conversion module. The power supply and voltage conversion module is in circuit connection with the LED light source module and the CPU and used for converting one path of the power supply of the power supply and supplying the converted power supply to the LED light source module, and the other path of the power supply of the power supply outputs 3.3V voltage to supply power for the CPU. The CPU is used for receiving human body signals detected by the detector and ambient light signals acquired by the photoreceptor and outputting control signals to the LED light source module. The novel intelligent energy-saving long-life and human body induction type LED lamp has high optical efficiency and long service life, is energy-saving and environment-friendly, and the light is soft and not glaring.

Description

technical field [0001] The invention relates to the field of LED lamps, in particular to a novel energy-saving, intelligent and long-life human body induction LED lamp. Background technique [0002] Today, when the world advocates low-carbon and energy-saving, energy-saving lamps have become the first choice for people to use lamps, and human sensor lamps, as one of the representatives of energy-saving lamps, are widely used in stairs, corridors, parking lots, warehouses, toilets, etc. The occasion of human manual control. It has the function of "turning on when people come, and turning off when people leave", which avoids the phenomenon that the lights are also turned on when no one is active, and has the effect of saving electricity and energy. [0003] The development of human body induction lamps can be divided into three representative generations based on the type of light source: the first generation: human body induction incandescent lamps; the second generation: hu...

AI Technical Summary

Problems solved by technology

[0005] The first generation, human body induction type incandescent lamps: low cost, moderate light source life, convenient and simple maintenance; but incandescent light sources have low luminous efficiency and high calorific value, which is not energy-saving compared with fluorescent lamps and LED lamps, and is harmful to the lamp body. High temperature resistance requirements of materials

[0006] The second generation, human body induction fluorescent lamps: moderate cost, high light source luminous efficiency, low calorific value; but due to the characteristics of fluorescent lamps, fluorescent light sources used in induction lamps have short impact life and high maintenance costs; the light source contains heavy metal mercury, Not environmentally friendly

Human body induction LED lamps are currently popular induction energy-saving lamps, but most of the induction LED lamps currently on the market have simple functions, and have the same features as the previous two generations of human body induction lamps: they play the role of "people come to highlight, people come The distance delay breaks out", that is, the light does not turn on when no one moves at night, and the environment can be described as "darkness". When someone walks through the sensing area of ​​the sensor light, the light will suddenly turn on. The angle of view has a sense of impact, which can easily cause people to panic; when people leave the sensing area of ​​the sensor light but are still working or doing activities near the sensing area of ​​the sensor light, the light delays for a certain period of time (usually within 1 minute), and the sensor light "Suddenly" turned off, and the environment returned to "darkness". This shortcoming makes people feel a lot of inconvenience in reality.
