Types of LED and its Function


Light emitting diode or LED is a semiconductor light source that emit light when current flows through it. First appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared light, infrared LEDs are used in remote control circuits like tv remote. The first visible-light LEDs were of low intensity and limited to red. Early LEDs were often used as indicator lamps, replacing small incandescent bulbs. Later developments produced LEDs available in visible, ultraviolet (UV), and infrared wavelength with high, low, or intermediate light output for instance white LEDs that we usually used for lighting our home, and here are basic types of LED and its Function

1. Color & Color Temperature LED

Color & color temperature LED refer to as RGB (Red, Green Blue), W(white) or WW (Warm White). Red, green and, blue LED is basic source of light spectrum we can extract out of the light spectrum, the warm white LED refer to as 2200 Kelvin to 3000 Kelvin are the combination of the RGB at the different spectrum. similar to the white LED which read from 3500 Kelvin to 6000 Kelvin, the use of color LED light depends on the function and purpose of space.

2. Color LED

The color LED attracts every person by the three varieties that commonly use in the market such as cool white LED, warm white LED, daylight LED. Most of the home use halogen bulbs which are warm white. The color in the daylight LED which has stark white and hint in it which is mainly used for highlighting the real color, mainly this type of LED is used for decorating indoor or outdoor places because of the varieties of the shapes and mounting

3. Linear Type LED

Linear type LED are designed to substitute fluorescent tubes whether it is in the solid tube form or in the linear strip type. This LED type are created general lighting environment to your space, it can be apply into the cove ceiling or it can apply into the lighting fixture hung from the ceiling above your house area.


It is expanded as a surface mounted device and it is popular in LED lighting. The SMD chips mounted in the bulb have additional brightness which is reliable in office and household such as LED strip lighting. This type of LED is also have been implemented in torch or flashlight and many portable lighting sources


The COB stands for chip on board which is another LED generation and offers a strong amount of light than SMD and has an accessible option as the user considered a beam of controlling light. It serves a better watt ration to lumen that signifies as it has high productivity. This COB LED have the same function as SMD but in higher and upgraded capacity.

That’s all few basic types of LED that is commonly used in the household or office area. So, which one is suitable for your needs and functionalities? Lots of people think that they can just simply go to the ecommerce and buy what is there based on the rating and review, yes you can but now there is professional lighting platform to give you consultation and the sourcing solution that suit your needs. #Bloxlimited #Sparklighting
