Light-emitting diode (LED) desk lamp with adjustable color temperature and brightness and control system and method thereof

Abstract

The invention relates to a light-emitting diode (LED) desk lamp with adjustable color temperature and brightness and a control system and method thereof. An LED light source of the desk lamp is formed by combining and arranging LED light-emitting sources of at least two color temperatures. A signal collection module is used for receiving control signals of color temperature control switches and brightness control switches and transmitting the signals to a micro control processing unit. The micro control processing unit is used for generating corresponding adjusting control signals to a rear-stage light source driving module according to preset control strategies corresponding to the color temperature control switches and the brightness control switches to drive the corresponding LED light-emitting sources to emit light. Color temperature adjustment is achieved through the plurality of independent color temperature LED light light-emitting sources and combination of the sources, the continuous adjustable change range of the brightness of the light sources of each color temperature is 0%-100% of rated power of the desk lamp, the color temperature and the brightness can be set according to the requirements of life and working environment conveniently at any place, and working life lighting quality and efficiency of users are improved.

Description

Technical field [0001] The invention relates to an LED table lamp, in particular to an LED table lamp with adjustable color temperature and brightness, and a control system and method thereof. Background technique [0002] At present, people use a wide variety of lighting fixtures. Among them, desk lamps are the most used lighting fixtures. In order to facilitate concentration, most common desk lamps use cold white desk lamps with a color temperature of 5000K to 7000K. The development of intelligent and humanized lighting technology makes people not satisfied with simple reading and learning. Table lamps are often used to create a warm and relaxing lighting atmosphere required for leisure and entertainment. This requires table lamps to provide lighting capabilities with multiple color temperatures. The common desk lamps on the market generally only provide one or two color temperature lighting capabilities, and cannot adjust the required color temperature according to the actual ...

Problems solved by technology

The development of intelligent and humanized lighting technology makes people not satisfied with simple reading and learning. Desk lamps are often used to create a warm and relaxed lighting atmosphere for leisure and entertainment. This requires desk lamps to provide lighting capabilities with various color temperatures. The common table lamps on the market generally only provide one or two color temperature lighting capabilities, and cannot adjust the required color temperature according to the actual environment. In addition, people's working and living conditions are different, and the required lighting brightness is also different. There is a big difference between the required lighting brightness and the sleeping lighting brightness. Although many lamps on the market have dimming function, they are all aimed at the brightness adjustment of a single color temperature. It is difficult to adjust multiple color temperatures and brightness at the same time.
