Abstract

The present invention provides a lamp assembled from a LED with a high brightness and a control circuit thereof. The lamp comprises a plurality of LED (light emitting diode) sets. Each LED set comprises red, green and blue LEDs with a high brightness. One end of each of the red, green and blue LEDs is connected to a power source. The other end of each of the red, green and blue LEDs is separately connected to a driving circuit belonging to one color group. The driving circuit has a trigger end. When the trigger end is triggered by a trigger signal, the driving circuit becomes conductive in order to illuminate a corresponding red, green or blue LED. By controlling the on/off and brightness of the red, green and blue LEDs, the lights of the LEDs form a desired color and brightness.

Creation instructions (2) The copper head is the same as that used by ordinary light bulbs. However, although the two cases mentioned above use LEDs of different colors to achieve the effect of mixing light, they only control the ON or OFF status of LEDs of a certain color. There is no control on the brightness of LEDs. The color after its color mixing is relatively simple and has no change. For example, it can only mix red and green LEDs with the same brightness into a yellow light source, but it cannot maintain the red LED's original brightness and reduce the brightness of green_. Mix up the 圼 orange light source. In addition, the so-called high-brightness LED (light-emitting diode) refers to an LED that can generate high-brightness. Generally, 50aA is applied to a high-brightness LED, and a brightness of 1 candle can be obtained. Moreover, its long service life can be as long as about 100,000 hours. Therefore, the inventor wants to use the characteristics of high-brightness LE: D to develop a high-brightness LED lamp and its control circuit. The reason is that under the guidance of the above-mentioned invention concept, the inventor was assisted by his rich professional knowledge and many years of practical experience, and after much hard work, he finally carefully developed the invention. Another object of the present invention is to have a power saving effect. Another object of the present invention is to have a long life effect. The third purpose of the present invention is to have the effect of adjusting brightness. The fourth purpose of the present invention is to have the effect of dimming color.
