Embodiment Construction

[0045] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0046] It can be known from the principle of color mixing that any color of light, including white light, can be generated by using the three primary colors of RGB, red, green, and blue. The light source synthesized from the three primary colors has obvious advantages over the traditional white light source. On the one hand, the RGB three-color LED light source improves the color spectrum, making the color of the light source rich and expressive; on the other hand, the RGB LED only emits red, green and blue light, and does not emit other unnecessary colors. This also greatly improves the conversion efficiency of energy and saves power consumption. Therefore, the present application provides an LED lighting system based on the above principles.

[0047] see figure 1, according to an embodiment of the present application, the LED lighting system inclu...

Abstract

The invention discloses an LED lighting system. The LED lighting system comprises a microprocessor for outputting a first pulse width modulation signal, a second pulse width modulation signal and a third pulse width modulation signal, a first constant-current driving module for outputting a first current according to the duty ratio of the first pulse width modulation signal, a red LED lamp set for outputting corresponding luminance according to the first current, a second constant-current driving module outputting a second current according to the duty ratio of the second pulse width modulation signal, a green LED lamp set for outputting corresponding luminance according to the second current, a third constant-current driving module for outputting a third current according to the duty ratio of the third pulse width modulation signal, a blue LED lamp set for outputting corresponding luminance according to the third current and a power module. According to the LED lighting system, colors can be set, and meanwhile brightness and darkness adjustment and soft switching protection and overheat protection of LED lamps can be achieved.

Description

technical field [0001] The present application relates to LED (Light Emitting Diode) lighting technology, in particular to an LED lighting system. Background technique [0002] Light-emitting diodes can convert electrical energy into light energy. Compared with traditional light sources such as incandescent lamps, they have many advantages such as low power consumption, long life, small size, and energy saving. LEDs are used in various fields, including traffic lights, road lighting, automotive instruments, projection displays, medical equipment, TV backlights, etc. At the same time, with the rapid development of embedded technology, wireless communication technology and sensor technology and the improvement of modern people's quality of life, people's demand for wireless, networked, intelligent and energy-saving home life is becoming stronger and stronger. Smart home It is gradually entering the modern family life, and the intelligent lighting system is an important part o...
