A mandatory condition - the driver's power should be more than all the LEDs in total. The more powerful the driver, the more LEDs you can connect to it (of course, you will have to perform simple calculations). The power of the device is the most importantcharacteristic. You can make a device on its basis literally "on your knee". On PT4115, the LED driver circuit is implemented quite simply - it is the most common voltage converter for use with LED elements. The inverter must provide a currentwhich LEDs will work with the same brightness.
The current has a direct dependence on the brightness and power of the elements. The voltage at the output of the converter directly depends on the type of connection of the light source, the number of LEDs. Driver Optionsīefore you buy a device or make it yourself, you need to familiarize yourself with what it has the main characteristics: From the network if the device is powered, it is enough to include a constant resistor in the circuit. In some cases (if light-emitting diode lamp of low power and powered by 220 V) it is possible to remove the LED driver circuit. If the LEDs are used in automotive or motor vehicles, drivers using DC voltage, 9-36 V, should be used. If you plan to carry out lightingLED lamps of a residential or office space, the driver must be powered from a 220 V household electricity network. This is a graph showing the relationship between the supply voltage and the current. To find out the voltage needed to power the LEDs, you need to use the current-voltage characteristic. The crystal in the LED will last much longer.
And you need to take into account that the current that passes through the crystal of the semiconductor should be exactly the same as that of the LED on the passport. The main purpose of the drivers is stabilizationcurrent that passes through the LED.
But before you start assembling, you need to determine what requirements for the device are presented - analyze the characteristics and types of devices. The meaning of the device - to convert the alternating voltage flowing in the network, into a constant (low). To collect independently the driver scheme for light-emitting diodes everyone can, if, certainly, there are knowledge of electrical engineering. In order for the LED lamps to workas much as possible brightly and effectively, special modules are used - drivers.
