advantage led module manufacturers cost of present, the LED module industry are continuing efforts to reduce costs. At present, most application vendors are using SMD LED to assemble a variety of lighting structures. As mentioned above, led module SMD LED light source compared to the use of more materials and manufacturing process, the cost of these important factors are taken into account. In the light source module led, led module manufacturers, due to the reduced number of SMD LED materials (such as aluminum plates, welding materials), as well as the production process led module manufacturers were the costs of Hebei led module, which can significantly reduce LED application costs. Analog adjustment mode PWM controller using the drive current is adjusted to stabilize the LED drive current, stable output light intensity. Since the feedback control signal is a PWM controller usually a voltage value, so is the use of an analog adjustment of the output drive current measuring resistor is sampled, wholesale led module, and converts it to a voltage feedback signal, the feedback voltage by PWM controller stability, so as to achieve the purpose of stabilizing the output drive current. Use analog adjust the output current is adjusted there is a big problem LED output light intensity method: the LED output wavelength will change as the LED drive current variations occur, so that different output light intensity, white LED die set color temperature will change. In order to overcome the above drawbacks, it has developed the LED drive current mode PWM regulator.
