Product Description

RGB/RGBW Bluetooth controller is a universal mobile control RGB/RGBW controller, using the bluetooth 4.0 technology and the most advanced PWM (pulse-width modulation) control technology. It can control all 5 line 4 circuit (anode) full-color LED lighting products, such as LED modules, LED light bar, LED light box, etc. It has the advantages of convenient connection and use simple, and memory storage, with light synchronous display. Through the mobile phone to control the mode selection, brightness adjustment, speed regulation, and other functions. According to the customer actual demand it can realize the colors jump, the gradient changes, such as dynamic light stroboscopic effect.

Q:How is the LED light connected to the dimmer?
To see what type, the controller is generally is thyristor dimmer, dimmers has four lines, two input two output, two input LN the zero line, the rest two led lamp with power line
Q:What do you mean by PWM
LED's dimming control has traditionally been done by using a DC signal or filter PWM to adjust the forward current in the LED. Reduce the LED current will rise to adjust the intensity of the LED light output, however, the change of the forward current will also change the LED color, because the shade of the LED will change as the change of electric current. Many applications (such as car and LCD TV backlighting) cannot allow any colour drift in leds. In these applications, due to the light are different in the surrounding environment changes, and human eyes are sensitive to Yu Guangjiang tiny change, so wide range of light is required. By applying a PWM signal to control the LED brightness, the leds are tuned without changing color.
Q:Why PWM? Does it have any unique advantages
1, the PWM dimming ensures that the LED color index and the light color, This is also the advantage of PWM, and is convenient for digital signal control because the digital signal is as long as the level is low and the change is in the pulse width
Q:The difference between a 100v dimmer and a 220v dimmer
In multiples of 220 v voltage is 110 v voltage, if used in the dimming, the effect certainly is not the same, their different rated voltage 220 v voltage in 110, the 110 v voltage cannot be used in the 220 v voltage
Q:Silicon-controlled incandescent lamp principle.
One way to control silicon is only positive half waveguide, which is equivalent to diode, and the actual power consumption of incandescent lamp is 1/4. It's 1/8 when the Angle is 90 degrees. Both sides of the two sides are able to guide the positive and negative half wave, and the actual end of the incandescent lamp is full voltage, and the power consumption is one. The positive and negative half waveguide angles are 1/4 for all 90 degrees.
Q:Now, there are several leds. What principles do they use
The rear edge controls the dimmer, which is made of FET or insulated gate bipolar transistor (IGBT). The MOSFET is normally used as a switch device by the cutting phase dimmer, so it is also called MOSFET dimmer, commonly known as "MOS tube". MOSFET is an all-control switch that can be controlled or controlled, so there is no such thing as a completely controlled switch. Other MOSFET dimmer than the silicon controlled rectifier circuit is more suitable for capacitive load dimmer, but because the cost is high and the dimming circuit is relatively complex, stability and other characteristics, it is not easy to do the MOS tube dimming is not developed, silicon controlled dimmer still occupied most of the adjustable optical-intensity system market.
Q:What happened when the LED power was dimmed?
Dimmer and the LED driver is not compatible, there is a strong possibility is LED power is too low, can't meet the minimum load power of dimmers, LED to the dimming instability, it is possible that move light way, PWM dimming, for example, if the dimmer switch frequency and just drive to switch frequency, noise can occur, to achieve stable dimming, different dimmers have different brand, watch what you chose, different brands have different methods.
Q:110V light LED lamp (tube lamp), how to match better
My lamps and lanterns is dimming power supply with a power supply with a lamp, just to the customer to 110 v voltage, the voltage of 220 v I'll have to buy the 220 v to 220 v transformer can try ah, is to use the transformer and then have the above case, dimmers unworthy, but there is a range it is normal that move light, so don't understand what the problem.
Q:Why does the light bulb flash? The customer is doing the lighting up
Energy-saving lamps are generally not adjustable, Halogens and leds are better tuned
Q:Why can leds not be used for dimming circuits and electronic switches
The brightness range from 100% to 50% (the Toshiba says they can do 0-100%, I doubt). With these two methods, you can make the leds 15-100% dimming. But special lighting fixtures and corresponding dimmers must be chosen.
