LEDRunLights, Manufacturer of high power LED Module and LED light products for General lighting applications. LED Run Lights introducing a unique energy efficient 0.1 to 0.5W and high power 1Watt LED's, The LED designed with exceptional heat dissipating capabilities and high efficient thermal management that increases the LED performance. LED Run Lights (LEDRL) manufactures the LED lens with special material that will not change the optical characteristics during time. How to connect LED's What we need to know? Numbers of LED, LED Voltage and current, power source Voltage and current. One of the requirements to run LED it is to connect Resistor to the LED. we must to connect a resistor in series to the LED to limit the current through the LED, otherwise the LED will "burn" in a short time. The resistor Value , R is given by R=(VS-VL)/I VS= the Supply Voltage, VL= the LED Voltage (please E-mail/ask LEDrunlights for VL) I = the LED current (please E-mail/ask LEDrunlights for I) How to choose the resistors? choose the nearest standard resistor value which is greater then the calculate value, if the calculate value is not available. Higher resistor value will decrees the LED current and increase the LED life but it will decrees the LED brightness. How to connect 9 LED's or more Note: LED run lights usually using high power LED with VL= 3.8VDC and the current I=180mA. we can use the high Voltage and Amp in the LED because of the LEDrunlights design, the LED design with exceptional heat dissipating capabilities and high efficient thermal management. 1 LED, 2 LED's, 3 LED's, 4 LED's, 5 LED's, 6 LED's, 7 LED's, 8 LED's, 9 LED's
