PRODUCT FEATURES
Function
Universal LED dimming module supports the lithium ion battery, lead acid battery, USB power supply equipment. Can be widely used in 5V, 12V, 24V lighting and other occasions, such as automobile, motorcycle, bus. Can also be used in home decoration, high-power lamp, lamp, lamp panel and so on. Dimming interface rich, equipped with a potentiometer PWM dimming, dimming, dimming dimming touch three. Intelligent lighting choice. Can be individually adjustable, can also be carried out at the same time PWM dimming and potentiometer dimming, dimming potentiometer or touch and at the same time. Potentiometer dimming can be brightness to 5% the following, PWM dimming or touch dimmer can brightness to 1% below. Potentiometer dimming no stroboscopic problem.
Three, the use of methods
(1) first potentiometer clockwise rotation in the end, makes the output current minimum (<100mA), to avoid burning lamp.
(2) output of the LED lamp string into the current table after receiving module L+, L- port. The power supply receiving module V+, V- port. Note: the work of the LED module connected to the total voltage must be greater than the input voltage of 3V and above, or may burn the lamp! Input module, output can not reverse connection or short circuit!
(3) to adjust the rated output current. This process is the output current stage to adjust the maximum lamp. If with a touch function, first open the touch dimmer, will touch light modulation to maximum state. Reverse adjust potentiometer, lights, and observe the current meter. Until it reaches the current needs, adjust the end. Since then, no longer need to adjust potentiometer.
(4) dimming
If an external PWM signal light adjustment, an external PWM signal access module PWM, V- port. Change of PWM signal duty cycle can be stepless dimming, output current to the rated maximum between changes in 0.
If touch dimmer, click the touch (touch duration less than 550ms), bright lights can realize the control of. One click touch, light; click again on the touch, the lamp. So the cycle.
Long press the touch (touch duration greater than 550ms), and can realize stepless adjust the brightness of light. A long press the touch, the brightness of the light gradually increased, when loosening the brightness of the light brightness corresponding to stop in loosen the moment, if long in time for more than 3 seconds, then the brightness of the light to reach the maximum brightness and then don't change; again, long in the touch, the brightness of the light gradually decreased, when loosening the brightness of the light brightness corresponding to stop in release time, if the long according to the time for more than 3 seconds, then the brightness of the light to reach the minimum brightness after no change. So the cycle.
(5) common problem analysis (using the read before)
[a] potentiometer, PWM, touch can not control the lights, light has been lit, or LED can not completely shut out, why? Is it right? Module bad?
Many customers encounter this problem, first of all, dear how much is the input voltage? How much is the output voltage (must multimeter measured data, the output voltage by experience often go wrong)? We must ensure that the input voltage is less than the above output voltage 2V, module to work properly, otherwise the potentiometer, PWM, touch can not control the lamp burning, even burning lamp! Because the boost Boost circuit if the output than input low, direct current from a diode to output. Also some customers only received one PWM line, no common grounding wire signal and module, of course not.
[b] PWM control lamp brightness why accounted for between air ratio and the light should not be linear regulation?
Ensure that the PWM frequency between 100-300Hz, can be used with linear output current duty ratio control.
[C] why the module output 45V, received such a high LED will burn out the light?
This module is a constant current output, when the output no-load output voltage module, automatic increases, pressure limiting circuit is limited to 45V, when the access load, the output current is constant, the output voltage is determined by the load. This is characteristic of constant current output. Dear friends as long as the guarantee that the output current do not exceed the load rated current, voltage will automatically adjust the oh.
[D] how to use an external knob potentiometer adjusting light?
Adjust the output current the desired according to the front steps, after a good tune measured at board blue the resistance value of the potentiometer Rx. Using Rx fixed resistor in series to the external adjustable potentiometer (resistance value is 1K) can be an external potentiometer dimming. Rx serves to limit the maximum current effect.
