Problems solved by technology

Among them, compared with the old-fashioned mechanical button control, although the touch screen control has made a lot of progress and the feeling of use has been significantly improved, it still cannot meet the needs of convenience, so the manufacturer has developed an infrared method. To control LED lamps
Among them, the general method of using infrared technology to control lamps is infrared gesture control and infrared remote control, and both methods have their own defects, such as infrared gesture control can only be used for the switch of lamps, but cannot adjust its brightness; relatively, Infrared remote control requires an independent remote control, which is not convenient enough
Therefore, both methods are not conducive to solving practical problems well, and a new technical solution is needed to completely and effectively improve the problems existing in the existing technology

Embodiment 1

[0055] like figure 1 Shown is an infrared gesture dimming system that can be used as a preferred embodiment of the present invention, including an obstacle and an LED light group, and an infrared transceiver unit and a logic processing unit are sequentially connected between the obstacle and the LED light group. The obstacle is the palm of a person or other parts, which may also be replaced by other objects that can reflect infrared signals.

[0056] Wherein, the infrared transceiver unit includes an infrared transmitting circuit unit, a driving amplifier circuit unit, an infrared receiving circuit unit, a signal amplifier circuit unit and an infrared modulation and demodulation circuit unit, wherein the infrared modulation and demodulation circuit unit includes a modulation unit, a demodulation unit and a logic output unit.

[0057] In addition, the logic processing unit includes a logic processing circuit unit and a voltage control circuit unit.

[0058] The modulation uni...

Embodiment 2

[0084] like figure 2 Shown is an infrared gesture dimming system that can be used as a preferred embodiment of the present invention. Specifically, based on the system described in Embodiment 1, a band-pass filter circuit is added between the infrared receiving circuit unit and the signal amplification circuit unit unit. At the same time, in the logic processing unit, the logic processing circuit unit is replaced by the relay control circuit unit, and an analog quantity latch circuit unit and an AC / DC conversion circuit unit are added at the same time.

[0085] The connection relationship is transformed as follows: the modulation unit, the drive amplifier circuit unit, the infrared emission circuit unit, and the obstacle are connected sequentially; the obstacle, the infrared receiver circuit unit, the band-pass filter circuit unit, the signal amplification circuit unit, and the demodulation unit Sequential connection; logic output unit, relay control circuit unit, and analog...

Abstract

The invention discloses an infrared gesture dimming system and a logic and analog control method thereof. The infrared gesture dimming system comprises a barrier and an LED lamp band, wherein an infrared transmitting and receiving unit and a logic processing unit are sequentially connected between the barrier and the LED lamp bank. The technical scheme of the invention provides a more perfect and convenient gesture control lamp mode, so that brightness is regulated by waving hands, an LED lamp is switched on or off and the brightness of the LED lamp is regulated by common simple gestures, perfect functions are achieved, additional remote controllers are not needed for carrying out control; and the infrared gesture dimming system has the characteristics of non contact, sanitation and safety, also has a better user operation experience, and has a more favorable popularization and application effect in practical use.

Description

technical field [0001] The invention relates to the technical field of LED lighting control, in particular to an infrared gesture dimming system and a logic and analog control method thereof. Background technique [0002] Lamps, especially LED lamps, are currently widely used in people's lives and have become indispensable household appliances. With the development of technology and the continuous changes and sublimation of people's needs, users are no longer satisfied with using the original mechanical buttons Therefore, the control methods of LED lamps have gradually become more diversified. Among them, compared with the old-fashioned mechanical button control, although the touch screen control has made a lot of progress and the feeling of use has been significantly improved, it still cannot meet the needs of convenience, so the manufacturer has developed an infrared method. To control the LED lamps. Among them, the general method of using infrared technology to control ...
