rgb led high power and led car use

The basic use of the controller reduces the cost of the car displays, signal and lighting electronic equipment. Switch adjustment circuit in the highest efficiency light LED to control the brightness of the lights.

Recently, LED tube has been replaced by low-voltage halogen technology, widely used in the car for general lighting. Design engineers have long life and low operating DC voltage LED lighting two advantages quickly gave approval.

On the other hand, in order to make these new LED technology to develop, you need to use more complex, more expensive vehicle electronic control system. The emergence of new ultra low-end 8-bit microcontroller (MCU), allowing design engineers can significantly reduce the cost and complexity of the system, use this alternative lighting solutions to be able to be profitable.

Due to the use of low-end MCU, high-brightness LED tunnel (HBLED) has developed many new applications, to continue to attract more users. New input, the HBLED including: monitor, car signs, lights, mobile devices and lighting equipment.

Overall, the LED has a nonlinear volt-ampere characteristic, the need for limiting the control of power consumption and light output of these two important factors. Power consumption and light output depends on the current drive the HBLED the ideal power is the constant current source. The high brightness LED lights, standard LED in its output power. Traditional LED output power is typically limited to below 50mW, but HBLED is able to provide 1-5W of output power.

Want to get the constant current source in many different ways, such as the use of series resistors, linear current source or switching regulator. The use of the switching regulator is the most common energy-saving solution. Switching regulator to cut off the input voltage, the duty cycle to control the average current, in order to achieve its current control – when the load requires a higher load current, the circuit connected to the time extension to fit the load current changes .

The HBLED the current is generated by the average power stored in the inductor L within. Switch is closed, the inductor will store energy as much as possible, the current flowing through the HBLED will be enhanced until it reaches the maximum or switch off. Then, when the switch is turned off, the energy stored in the inductor will provide HBLED current. This current will gradually weaken until you reach the minimum or switch is again closed.

Current control to solve the problem becomes very simple, based on the the HBLED above the MCU controller dimming. Right the HBLED to implement dimming There are many different techniques, some of which may include the patent issues. Under any conditions, the dimmer on the same basis, namely: fully open in the HBLED the normal operating current HBLED period of time, and then completely to the continued closure of the period of time. Periodically at a faster rate to complete the action (the human eye can see) to give the impression HBLED light levels darken. The three techniques most commonly used are: pulse width modulation (PWM), frequency modulation and the bit angle modulation.
