Dual heatsinking structure:

The heat could be radiating from both PCB directly and laser ceramic surface by sapphire. This dual heatsinking structure allows us to make COB at smaller size but higher wattage and better reliability.

COB Dual Heat Sinking Channel


LM80 approved:  One and only supplier who gets LM80 report for 600w single chip

Application:  Suitable for fixture requiring for narrow B.A angle&long distance. Such as port, stadium, and other high mast application

LM 80 approved 600w


Copper PCB Board: 2 times higher heat dissipation than aluminum PCB

Patented laser- ceramic:  Laser ceramic developed by CAS, high temp resistance and conductivity, perfect replacement for traditional phosphor in the led chip.

New generation LED lighting


Extra high power: Maximum power of single COB could be up to 1300w

KCOB ceramic characteristic curve: The phosphor ceramic can return to the original state even after 300 ℃. While the phosphor powder can not be back after 250 ℃, the performance would remain in the  decaying state



*Size & Circuit is customizable based on the requirement

K-COB (Maximum power for single chip could reach 1600w)
K-COB LED arrays provide the industry’s best lumen density and efficacy for metal-based chip-on-board (COB) LEDs in industry-compatible footprints and LES sizes. This COB family features an innovative exclusive patent phosphor ceramic technology as well as dual heat-sink technology to deliver higher reliability and output than competing products. The K-COB LED arrays include 10 LEDs across three (9.8 mm, 14.5 mm and 22 mm) LES sizes with standard color options of 70, 80 and 90 CRI. Premium color options that include high fidelity (98 CRI) and specialty color points are available to deliver color quality without compromise in efficacy, lumen density, color consistency and reliability.

The K-COB Series is a comprehensive range of metal-based COBs available in various LES, CRI, CCT, efficacy, and drive current options. The heat could be radiating from both PCB directly and laser ceramic surface by sapphire.
This dual heatsinking structure allow us make COB at smaller size but higher wattage and better reliability.
The Phosphor ceramic is the high heat conductivity rate: 13.367W/m.k, 75 times of traditional phosphorus powder (YAG 05+sil1018), which ensures excellent lumen maintenance and color stability even in high lumen applications. Tight color binning ensures fixture-to-fixture uniformity. A 97 CRI (90 R9) version is available for color-critical applications.
