COB LEDs for lamp and fixture makers
A COB (chip on board) LED packs many LED chips under one yellow phosphor window, so it gives a single, strong point of light. Lamp and fixture makers use COB arrays for spotlights, track heads and downlights. We supply low-voltage DC arrays as components.
A COB LED is an array of chips on one board that works as a single light source. We quote low-voltage DC COB arrays from about 5 to 100 W in warm to cool white (2,700–6,500 K). They need a heat sink and a constant-current supply, which you source locally.
Typical specifications
| Power | about 5–100 W per array |
|---|---|
| Colour temperature | 2,700–6,500 K |
| Supply | low-voltage DC, constant current (power supply not included) |
| Data | datasheet per model: voltage and current range, size, light output |
Typical values from our catalog; each quote confirms the exact values of the model.
COB or SMD?
SMD LEDs spread light over many small points, which suits strips and panels. A COB array gives one round source with a uniform look, which suits optics, reflectors and spotlights. COB arrays run hot, so plan the heat sink before you choose the wattage. For many small points, see SMD LEDs.
We supply components only
We sell the COB array, not the finished lamp and not the mains power supply. If your finished product connects to mains power, it may need its own approval in your country: check your local rules for the product you build.
Questions buyers ask
What does COB mean?
Chip on board: many LED chips mounted directly on one substrate and covered by one phosphor layer.
Do COB LEDs need a driver?
Yes, a constant-current DC supply matched to the array's voltage and current. We do not supply drivers.
What is the price and minimum order?
We quote both per model and quantity, with the datasheet.
