Main specialty
1. 14% better luminous efficiency than existing products
Through the improvement and optimization of the parts, the light extraction efficiency and heat release are improved. Compared with the existing products of the company, the brightness is increased by 8% and the luminous efficiency is improved by 14%. In the COB type high power LED, very high light emission is realized. effectiveness.

2. Balance high efficiency and improve color rendering
In the field of outdoor lighting applications where luminous efficiency is prioritized, market demand for improved color rendering has recently increased. Generally, the improvement of color rendering results in a decrease in luminous efficiency. This new product has improved color rendering from Ra 65 typ. to Ra 70 min while maintaining the existing brightness and luminous efficiency. In addition, the addition of 3,000K and 4,000K color temperature varieties meets the need to ensure light quality and market diversification in the outdoor lighting market.
3. Efficiency of appliance design
Achieving a range of luminous fluxes from 10W incandescent lamps to 400W mercury lamps in existing light sources typically requires hundreds of sources. The 4 series 11 varieties of products published this time cover the luminous flux in the range of 30lm to 22,473lm (0.2W to 165W), making the common optical design of LEDs feasible and improving the efficiency of lighting design.
4. Obtained UL specification (UL8750) certification
Obtained the North American UL Safety Specification (UL8750) certification. The use of UL-approved LEDs makes it easier for the fixture body to achieve UL certification.
5. Excellent exothermic and uniform light
The Chip on Alumi method (the company's patent) is an excellent heat release method in which an LED chip is directly mounted on a circuit board.
Considering the optical design of the lighting fixture, the uniform configuration of the light-emitting surface is achieved by the optimal arrangement of the chip. 
Approximately 1/9 of the "MacAdam Ellipse 3-Step" color management standard of ANSI C78.377 specification*3, the chromaticity deviation of the LED is almost undetectable (except for the Ra 70 min. type). 
6. Use our company's LED selection tool software to make LED selection quick and easy
In order to assist lighting manufacturers to select LEDs, the company has prepared LED selection tool software, which can quickly and easily find the relevant LED model products by inputting parameters such as luminous flux in the software. The LED selection tool software is available on the company's official website.
