    COB LEDs

    COB (Chip on Board) LEDs are compact LED modules with a bright light output. They consist of a small square or circular substrate which houses multiple LED chips/dies. These are covered with a phosphor coating. The most common colour of COB LED is white, however there a few more colours available as the technology develops.

    How do they work?

    COB LEDs have a base substrate, made of aluminium or ceramic, on which the LED dies are mounted. The actual LEDs provide a blue light. The number of LED dies and their typical luminous flux determines the "brightness" of the COB LED.

    The layer of phosphor, which is an orangey-yellow colour, sits on top of the LED dies. The phosphor converts the blue LED dies into a white light. The type of phosphor creates different colour temperatures.

    What is colour temperature?

    Colour temperature describes the warmth or coolness of the LED light output. "Warm" COB LEDs offer a yellow-orange light output while "Cool" COB LEDs tend to be a bluer white. Colour temperature is measured in Kelvins with the symbol "K".

    What are the advantages of COB LEDs?

    • Higher LED density than traditional LED mounting process

    • No need for multiple soldering - just one package

    • Bright light output

    Uses for COB LEDs:

    • General purpose lighting

    • Downlights

    • High Bay lighting

    • Low Bay lighting

    • Spotlights

    • Solid State Lighting (SSL) replacements
