In addition, the general electronic circuitry, likely to cause shortened life problem, mostly occurs in an electrolytic capacitor, caused by the magnetic component life! To effectively improve the life performance led module drive circuit can go towards the electronic circuit in the electrolytic capacitor, to magnetic component design for Reflection, effectively the life of the drive circuit performance longer. More importantly, color led module, integrated light engines from photoelectric lighting products're just a shell package, as long as customers spend less than one minute of time can it be assembled into a lamp, almost without any equipment. In other words, lighting plant without additional equipment and labor, based on the expansion of production capacity at times or even dozens of times, effectively reducing the processing costs. Full-color LED unit board color temperature adjustable LED drive circuit design in order to stabilize the output light intensity, color temperature p10 led module, and to achieve light intensity, color temperature adjustment, a kind of indoor full color LED unit board drive circuit block diagram shown in Figure 4, which were used with blue, green and red filters light intensity detector constituting the full-color LED unit board of three kinds of LED light intensity monitor and control through the AVR microcontroller, change corresponding to the duty cycle of the PWM control signal led module accessories, stable blue, green, red 3 LED light intensity, to stabilize the full-color LED unit board of light intensity and color temperature, wherein each LED drive circuit are LT3474 used as the drive control chip. Color led module _ Gao Jin photovoltaic (certified) _led module provided by Jinan Optoelectronics Technology Co., Ltd. Gao Jin. Jinan Gao Jin Optoelectronics Technology Co., Ltd.
