Luums - LEDs work for a better future

LED is the abbreviation for ‘Light Emitting Diodes’. A LED is a semiconductor which emits light. A single LED is small and gives relatively small light output. By grouping them the light output rises. The color of the LED depends on the material used. A LED bulb is made of a group of LEDs. All the characteristics of the LEDs used together determine the emission angle, luminous flux, light intensity and color display.
