Description of drawings
Fig. 1 is schematic block circuit diagram of the present utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited to this.
Embodiment
A kind of remote control LED light fixture, the LED lamp that comprises remote controller, control circuit, drive circuit and several different colours, described control circuit comprises radio receiving unit and control unit, radio receiving unit is connected to control unit, described control unit is connected respectively to the LED lamp of several different colours by drive circuit, the described radio receiving unit of described remote controller wireless connections is used for sending control command the brightness of the LED lamp of several different colours is regulated.
The LED lamp of described several different colours comprises the LED lamp group of the serial or parallel connection of redness, green and blue three kinds of colors, and it is divided into the respectively controlled circuit of three lamp groups by color and controls.
Remote controller comprises guidance panel and sender unit, guidance panel has on ﹠ off switch, adjusting key etc., can carry out various settings, the setting operation that carries out as people is transformed into the signal of telecommunication, convert wireless communication signal to by sender unit and be emitted to radio receiving unit, be forwarded to again control unit and analyze and send instruction to the operating state of drive circuit with the LED lamp that changes several different colours, comprise and turn on light, turn off the light or change brightness etc., realize the purpose of wireless remote control LED illuminating lamp.Also include timer at control circuit, can realize that the timing switch lamp is more convenient for people to the instructions for use of LED illuminating lamp.
Control circuit of the present utility model adopts the microcomputerized control chip, has low-power consumption, high-performance, I/O port and the characteristics such as low-cost flexibly.The microcomputerized control chip receives the wireless communication signal of sender unit, it is carried out the DSP decoding process, and obtains corresponding remote controller key value.According to the function definition of this button, produce digital pulsewidth modulation (PWM) signal again, driving LED lamp group is regulated lamp brightness.
Drive circuit of the present utility model adopts the LED type of drive of digital pulsewidth modulation (PWM), and is more energy-conservation than regulating resistance mode.PWM adjusts the LED drive current by changing pulse duty factor, realizes the brightness regulation of LED.The luminosity of LED is proportional to the pulse duty factor of PWM.The PWM operating frequency avoids human eye perceives to arrive the LED scintillation greater than 100Hz.Under this type of drive, the value linear change of duty ratio makes brightness change transition nature, brightness saltus step in the time of can not light modulation occurring.After single-chip microcomputer is decoded to wireless communication signal, produce three road pwm signals of corresponding remote keying function, drive respectively the LED lamp group of three directions.Drive circuit amplifies pwm signal, with driving LED work.
