Recently, people have paid more and more attention to the quality of life and entertainment products. The overall technology and technology have been rapidly transferred to the "multimedia entertainment". If the existing lights are controlled by a general switch, they will add a lot of voice control or Light & luminaires that change their silk effect, such as the Taiwanese paste announcement, the first touch, reveals a fixed voice-activated L-light case mount that can control the speed of the light and has a shuttle effect. _ and control line electric and long circuit board material elements, thereby forming a series of groups - with the size of the music, fast and slow to control the illuminating and rotating of the LED lights. Recently, due to the maturity of gas discharge lamp reading, the price of its products has dropped to the level of the ship that can be used to shout the body of the body, and the characteristics of the cold cathode lamp (CCFL) are the same. The high brightness of the company has led to a significant increase in market demand. However, due to the dimming device of the above-mentioned dimmer, the diligent mode or the fine-tuning signal to adjust its luminous light, the light-reducing effect of the luminaire is also reduced. The main purpose of the present invention is to use the sensing unit to detect the external sound, light and shadow, and the temperature-produced image signal 'to change the brightness, wavelength or dimming state of the light-emitting unit, to the entertainment effect of the film and television. . In order to achieve the above object, the present invention provides a dimming device for a light emitting unit, comprising: a power supply f element, providing - driving power; a crane unit electrically connected to the power supply unit, the driving unit generating a The operating frequency is to cut the driving power provided by the power supply unit; and the second=pressing unit converts the operating frequency of the driving power of the power supply unit to the operating frequency of the driving unit to be the second driving unit to drive the backlight unit to be illuminated; and at least— Inductive unit, used to detect _ outside ^ 5 200812431 ί and converted to - float to turn to test "shoot", a little bit of the relevant drive to drive the early 7L working frequency. [Embodiment] The detailed description and technical contents of the present invention will now be described with reference to the following drawings: As shown in the "Fig. 1" and "Fig. 2", the block of the present invention - the preferred embodiment is shown in the figure. The present invention provides a light-emitting single-shaped dimming device that adjusts at least a light state, wherein the light-emitting unit 9 is preferably a gas discharge lamp, such as xenon first k & (EEFL), the present invention emits light. The dimming device of the unit comprises: a power supply, and a σ unit to provide a driving power. In this embodiment, the power supply is used to receive power from the U and is filtered and rectified to convert the resident power to provide a power input. Open Q " Secret 1 force % force, and can use the guard frequency to turn off the power of the light single; in this embodiment, the drive unit 3 includes - connected to the secret cell to the unit 1 flute 1 connected power switch 3 The first-pulse width modulation controller (received) 32, and the front end of the f controller 32 is connected to provide a second output of the luminance unit 9 brightness level signal, and the first pulse width modulation controller 32 is used. To control the maximum brightness of the light-emitting unit 9 = the first variable control (10) to control the light-emitting unit 9 The change of the degree (4), the "middle" power switch 3G is preferably achieved by a transistor, and the brightness of the light-emitting unit 9 is further affected by the operating frequency of the light-emitting unit 9, and the common adjustment is based on eight operating frequencies. Adjusting the brightness of the light-emitting unit 9 in a proportional relationship; the driving power i of the power supply unit 1 is driven by the element 5' to drive the driving power of the unit (for the south voltage power, thereby driving the light-emitting unit 9 at the rear end to be illuminated, The transformer unit 5 can be magnetically sensitive (four) _ Μ _ (ρ ζ τ); and ^ 7 ° 5 ^ to ^ sensing unit 7, 帛 to measure an external signal (such as a sound test signal, wherein floating - in wavelength or _ state); Sensing unit; send ip9 ^ 贱 state (such as brightness, cry, early 7 °) for the microphone, thermal sense, photoresistor or image detection port. The description of 'Jing Xianyi used to measure image signals (such as RGB signal or Yang Muscle signal); In addition, 6 200812431 / The dynamic frequency reference axis rotation unit 3 turns off the brightness of the illumination unit 9 can be proportional change (see "Figure 3"), step change (see " Figure 4 shows) or a slow ladder change (see "Figure 5") * In this implementation, the floating _ rate reference __ the brightness of the entire illuminating unit 9, of course, the use of the floating frequency reference signal to adjust the wavelength of the light-emitting unit 9 or its dimming state (dimming) The invention relates to the hair-type dimming device of the present invention. The unit 7 uses the lateral θ, the wire, the temperature or the image domain of the side, and the illuminating unit of the illuminating unit. And can improve the manufacturing of the light-emitting unit 9 is more satisfied, and the short-term can not only increase the use flexibility and entertainment of the light-emitting unit 9 and improve the manufacturer's production force, so the present invention is highly advanced. The essentials of the 'Newfat, the Prayer Council grants the patent as soon as possible, and the second-detailed 'only the above' is only the preferred embodiment of the present invention, § does not limit the equal variation of the implementation of the present invention. Modifications, etc., are still within the scope of the patent application of the present invention. 7 200812431 [Brief Description of the Drawings] FIG. 1 is a block diagram of a preferred embodiment of the present invention; FIG. 2 is a preferred embodiment of the present invention.
