The specific type of fluorescent powder used in COB LEDs may vary depending on the manufacturer and application. Some commonly used phosphors in COB LED 24v include yttrium aluminum garnet (YAG), cerium doped yttrium aluminum garnet (Ce: YAG), and silicate based phosphors.
YAG based phosphors are widely used in white COB LEDs because they provide high luminous efficiency and stability under a wide range of operating conditions. Fluorescent powders based on Ce: YAG have higher efficiency and can produce warmer white light, making them popular in indoor lighting applications.

Fluorescent powders based on silicates, such as those based on europium doped strontium silicate, are also used in COB LED 24v to produce high brightness and efficiency in specific colors (such as green or blue).
In summary, the fluorescent powder used in COB LEDs depends on the required color temperature and specific application requirements.
There are several commonly used fluorescent powder brands in COB (Chip on Board) LEDs, including:
Intematix: Intematix is a leading manufacturer of LED phosphors, widely used in COB LEDs.
Dow: Dow is another major manufacturer of fluorescent powders for LED applications, and their fluorescent powders are also used in many COB LEDs.
Ria: Ria is a well-known LED manufacturer that also produces their own phosphors for their COB LEDs.
Lumileds: Lumileds is a company specializing in LED lighting solutions, using their proprietary phosphors in COB LEDs.
Samsung: Samsung is a major player in the LED lighting industry, producing their own phosphors for their COB LEDs.
These are just a small part of the many fluorescent powder brands used in COB LED 24v. The specific brand of fluorescent powder used will depend on the manufacturer and the specific application of COB LED.
