Light output control method and illumination system using cough method

The present invention relates to a light output adjustment control method, and more particularly to a light output adjustment control method applied to an illumination system including a plurality of sensing devices. Background technique

Light Emitting Diode (LED) is a kind of light-emitting component that can directly convert electrical energy into visible light and radiant energy. The principle of light-emitting is to apply voltage to the two terminals of the positive and negative electrodes in the semiconductor. When the current passes, the electron is passed. When combined with a hole, the remaining energy is released in the form of light. Depending on the material used and the level of the energy level, the photon energy produces light of different wavelengths. Therefore, the light-emitting diode (LED) usually has a low operating voltage. A series of characteristics such as low power consumption, high luminous efficiency, extremely short response time, pure light color, firm structure, impact resistance, vibration resistance, stable and reliable performance, light weight, small size and low cost. Therefore, there are many The lighting system uses light-emitting diodes (LEDs) as its lighting components to replace the traditional lighting components (such as: bulbs) with poor service life and poor performance. Generally, a light-emitting diode (LED) is used as an illumination system of the light-emitting component, and red, green, and blue (Red-Green-Blue, RGB for short) are used to allocate different colors of output light, and the user needs to adjust the lighting of the illumination system. For strong or weak color output, you can control the brightness of the lighting system or the color of the light by simply triggering the control interface on the lighting system (for example: button or knob) or by using the remote control.

However, household appliances with remote control functions have become essential functions in today's technologically advanced industries; various household appliances such as TVs, DVD players, air conditioners, and audio systems have their own appearances. Corresponding remote control, so when many remote controls are put together, it will cause users to use it, even when there is a remote control to use, but it can not be found. In view of this, an illumination system is proposed in the European Patent No. W2006/056814. As shown in FIG. 1, the illumination system 1 mainly includes an infrared transceiving sensing device 10 and a light emitting unit 11 when an object 100 is present. When the user's hand enters the sensing range of the infrared transmitting and receiving device 10, an infrared light 12 emitted by the infrared transmitting and receiving sensing device 10 is reflected by the object 100 to form a reflected light. 13 is transmitted to a receiver 101 included in the infrared transmitting and receiving sensing device 10, and the intensity of the reflected light 13 reflected by the object 100 received by the infrared transmitting and receiving sensing device 10 is inversely proportional to the object 100 to the infrared By modulating the square of the distance between the transmitting and receiving sensing device 10, the positional change of the object 100 relative to the infrared transmitting and receiving sensing device 10 can be estimated, thereby controlling and adjusting the lighting system. The brightness or color output of the light emitted by the light-emitting unit 11 in the system 1.

However, there are several obvious deficiencies in the adjustment of the brightness and color output of the light emitted by the light-emitting unit 11 by using the illumination system 1 provided with the infrared transmission/reception sensing device 10, for example, the infrared transmitting and receiving sensing device 10 It is susceptible to the brightness of the surrounding environment and affects the accuracy of its detection. Furthermore, the operating range of the infrared transceiving sensing device 10 is limited by the intensity of the reflected light 13 and is generally only about 30 cm. The operation within the scope of the present invention, therefore, how to solve the above-mentioned common technical means of the lack of, in order to develop the main purpose of the present invention.
