How Smart LED Desk Lamps Can Protect Your Vision

The goal of a smart home is to provide a safe, comfortable, efficient, and convenient living environment for human beings. With the continuous development of social science and technology level, the smart home industry has shown the development trend of the Internet of Things under the influence of the Internet and has attracted more and more attention from R&D personnel. Among them, green lighting research has become an important direction for the research and development of lighting facilities. Although the existing desk lamp can meet the basic lighting requirements, it cannot scientifically adjust the lighting intensity suitable for study and work according to the surrounding environment. As people spend more time with their eyes, more and more people suffer from vision loss. Therefore, the development of intelligent LED desk lamps with a high degree of automation, automatic dimming, and protection of eyesight came into being.

Light-emitting diodes (LEDs) are light-emitting materials with the highest electro-optical conversion efficiency to date. Lighting equipment with LED as a light source has been widely used in all walks of life, gradually replacing traditional light source lighting equipment. It has the advantages of high efficiency and energy-saving, low calorific value, small size, durability, fast response speed, low voltage safety, and so on.

1. The overall introduction of vision protection intelligent LED desk lamp system.

The eye protection smart LED desk lamp uses soft light LED as the light source device, which integrates functions such as automatic adjustment of light intensity, voice activation, infrared ranging, temperature measurement, and screen display to meet the daily lighting needs of users.

The desk lamp is based on an open source electronic prototype platform, and uses subsystem modules to design and develop functional modules such as automatic dimming, voice activation, infrared ranging, temperature measurement, and screen display, including 7 modules: (1) Soft LED lighting module; (2)) The light intensity acquisition module, the photosensitive resistance sensor collects the light intensity information and converts it into an analog electrical signal output; (3) The manual dimming of the lighting intensity of the desk lamp is completed by the potentiometer, and the adjustment knob can change the light intensity; (4) The voice-activated induction module is in the dark The power of the light is turned on by the sound intensity in the environment; (5) Manual and automatic mode switching is realized by capacitive touch sensor, touch the light once, and the working mode is automatically switched; (6) The infrared ranging module can independently transmit and receive characteristic frequency infrared, Detection distance, and has the function of prompt sound; (7) The ambient temperature signal acquisition is completed by the temperature sensor, and the temperature is displayed on the LCD screen after the program is processed.

2. Equipment function and realization.

When the vision protection smart LED desk lamp is working, touch the sensor to switch the working mode of the current desk lamp. If it is in manual mode, regardless of the intensity of ambient light and sound, the total power of the desk lamp can be turned on through the manual button switch, and the brightness of the desk lamp can be adjusted through the potentiometer; in automatic mode, the power can be automatically turned on according to the intensity of ambient light. The trigger sensor beeps and the LCD displays the current ambient temperature.

A vision-protected smart LED desk lamp based on an open-source electronic prototype platform, with a photoresistor sensor as an auxiliary device, proposes a new concept of automatically adjusting the intensity of the desk lamp. The system can directly set and adjust the light intensity signal through software, so as to achieve the purpose of automatic adjustment, thereby improving the comfort of the human eye. Various sensors are used as extended function modules to realize functions such as voice activation, infrared distance measurement, temperature measurement display, etc., making the lamps more intelligent. According to personal needs, add manual dimming function, control LED brightness through a voltage divider. After many times of debugging and improvement, the overall design is safe and reliable, simple in design, energy-saving and environmental protection, and has certain practicability.
