LED types: DIP, SMD, COB

LED types

DIP (Dual In-line Package)

This LED chip is the oldest technology.

The disadvantage of this system is the low intensity of the light.

SMD (Surface Mount Diode)

The most popular light source of LED lamps. The types of SMD LED Modules are distinguished by the dimensions of the LED chips.

Common types are 5050 SMD LED, 3528 SMD LED, 2835 SMD LED.

SMD LED Modules are widely used for backlighting, illuminations, advertising, automobile interior lighting, etc.

COB (Chips On Board)

This is a new LEDs technology that eliminates the drawbacks of its predecessors - heat dissipation is appropriate, light is clear, and thanks to the thin protective layer, the bulbs are healthy for the eyes.

This technology allows you to place a plurality of LEDs together as a single lighting module.

During the lighting looks like a panel lighting, the whole surface of the LED is full, there are no visible gaps as in DIP or SMD LEDs.

COB surpasses traditional lighting up to 50 times in terms of light output per centimetre of the surface illuminated.

This provides significant advantages compared to traditional lighting.
