Description of the invention: [Technical field to which the invention pertains] The present invention has a dimming method and a method for modulating light, and more specifically, is related to a light-emitting diode LE__ring and dimming drive The device and method can change the brightness by calculating the number of times of the switch 0N/0FF without changing the existing wiring, the existing lamp or the device, so that the driver has the dimming ❺H to the LED lamp, except for the original Wei. And increase the key selection function. [Prior Art] In the case of today's environmental protection and energy conversion rate, for lighting, because of the LED light bulb and the neon light, it has better electrical energy conversion efficiency, so it is used in the lamp. On the LED light has gradually replaced the trend of incandescent lamps and daylights. However, although LED lamps have the advantages of energy saving and environmental protection, however, with the current switch and lighting devices, LED lights are only on and off. Two choices, but not brightness selection. At present, the design focus of the LED driver of the LE:D lamp is how to stably drive the LED and keep its brightness unchanged when the input voltage changes. However, the disadvantage is that the LE:D dimming part, Control signals must be added to adjust, which has limitations and difficulties in practical use. As a result, existing wiring, lighting, 200950585 dimmers, etc. will not be modified or re-purchased for LEDS. Therefore, in addition to the new m or new wiring, with the current LED dimming design, it is difficult to directly replace the existing lighting device with existing dimming function. The fluorescent lamp illumination, because the fluorescent tube can not be dimmed, can only have two states of brightness and extinction. It is the choice of the brightness of Darin, and the combination of the number of bright tubes of different fluorescent tubes to select the brightness, however, Adopting this method will result in uneven lighting brightness in the county, X 'this way will be limited by the number of lamps that the lamp can support', so that the combination of each lamp will be limited and when the lamp When it is broken, it will have fewer exemptions. Therefore, how to stably drive the LED and replace the existing exposure with L in the LED driver design and application without changing the existing wiring, existing lamps or devices, except that the LED lamp has the original function. In addition, adding dimming to choose Wei is a problem to be solved.

The invention is also provided in the form of a light crane device and method, 200950585, which is used in a lighting environment of a light-emitting diode LED lamp, and the dimming driving device is required without changing existing wiring, existing lamps or devices. In conjunction with the Led driver, the brightness is changed by counting the number of times the switch is 0N/0FF, so that the Lm) driver has a dimming function, thereby enabling the LED lamp to have a dimming function, and providing dimming selection to select a suitable brightness. To achieve the purpose of saving electricity and environmental protection. According to the above-mentioned purposes, the bribe-spinning device, the dimming device, outputs a brightness control signal to the LED driver, so that the (10) driver has a dimming function, thereby allowing the LED lamp to have a dimming function. The dimming driving device of the present day and the month cooperates with the LE:D driver, and adopts the method of calculating the number of times of the switch 〇Ν/〇ρτ to change the brightness, so that the led driver has a dimming function, thereby allowing the LED lamp to retain the original In addition to the function, and increase the dimming selection function.
