50W Blue COB LED Chip, 220V AC Direct Power Supply
The 50W blue COB LED chip is a high-power lighting source based on Chip-on-Board technology, which is powered directly by 220V AC without requiring an external driver. It emits a uniform and intense blue light, with a wavelength in the 450-470 nm spectrum, suitable for decorative projectors, stage installations, signage, or DIY colored lighting projects. Its compact design on a ceramic substrate ensures efficient heat dissipation and a long lifespan.
What you get with this product
- Direct 220V AC power supply — no separate driver needed, simplifying installation and reducing project costs
- Pure blue light, 450-470 nm spectrum — vibrant and saturated color, ideal for decorative or stage effects
- Luminous flux of 2500-3000 lm at 50W — sufficient intensity for outdoor projectors or ambient installations
- 120-degree emission angle — wide light distribution, covers large areas without excessive intensity spots
- COB technology with marked L and N contact pads — quick and secure connection, no risk of phase reversal
- Compact octagonal format with mounting holes — integrates directly into standard light fixtures for 50W COB chips
How it works and how to install it
The XSY-5454 50W COB LED chip connects directly to the 220V AC mains via the L (phase) and N (neutral) contact pads visible on the board. No additional power supply or external driver is required. For installation, the chip is secured to an adequate heat sink for 50W power using the four mounting holes at the corners, and thermal paste between the chip and the heat sink is essential for correct operation and optimal lifespan. All electrical work must be performed with the installation disconnected from the mains.
Frequently Asked Questions
Does it need a separate driver or power supply?
No, the XSY-5454 50W COB LED chip is powered directly by 220V AC, with the driver integrated on the board.
What heat sink should I use for this 50W chip?
It must be mounted on a heat sink sized for at least 50W; without an appropriate heat sink and thermal paste, the chip will overheat and deteriorate rapidly.
Can this blue LED chip be used in outdoor projectors?
The chip itself does not have its own IP protection rating; water and dust protection is provided by the light fixture in which it is mounted.
