Long Lifetime
The new series has improved two properties which are required for lighting LEDs: one is long-term reliability which ensures constant brightness even if the LEDs are used for a long period of time, and the other is gas resistance. The two properties will contribute to the reduction in environmental loads as the improved luminous efficacy saves power (which leads to reduction of carbon dioxide emissions) and also reduces the frequency of change or repair of the LED light source and luminaires.

2-step Standardized for Ra80, 90, 97 series
2-step is about a half of the area ratio compared to the 3-step chromaticity range, has been realized
with all colors of Ra80, 90, 97 series.

High Efficacy
By improving LED packaging technology, higher efficacy than Ver.6 and Ver.8 is realized.

Significant improvement on luminous efficiency

Significant improvement on luminous efficiency by our spectrum tuning technology and narrow-band red phosphor (KSF/PFS) ※
・Efficacy 161lm/W ( 3000K Ra90min Tj85degC at rated driving condition )
・Ra90 High CRI and high luminus efficiency
・Two color models : On B.B.L. and Below B.B.L.
・Total 72 products with 3 standard package sizes and 9 types of die configrations

The world’s smallest LES COB, Φ2.4mm
Added the industry's smallest class lineup (LESΦ2.4mm)

Super High CRI with Narrower LES
High Intensity Series Ver.4 has realized the production of Super High CRI (CRI97)
through the use of our advanced phosphor and packaging technology.

Citizen Electronics Co., Ltd. has developed a “High-power UVC LED assembly product for disinfection (hereinafter called “UVC LED Assembly Product”). The product uses a high-power deep ultraviolet (UVC) LED that has a 265nm emission wavelength, which is assumed to have a high germicidal effect.

Characteristics 

1. With a high-reflection reflector, the product achieves uniform illuminance so effective disinfection is possible

2. Adopts a high-power UVC LED with 265 nm wavelength which has a high germicidal effect

3. A high-power assembly product enabling replacement with germicidal lamps, which are problematic as they contain mercury

4. Being dustproof and waterproof (equivalent to IP54), it can be used under various conditions *UVM001

Color homogeneity with unique COB’s structure

Our unique structure improves uneven light/color on the luminous surface.

Realization of uniform lighting 

Realize uniform lighting without unevenness and without using an optical lens specially designed for the product. This can shorten the design time, reduce material costs and more.

Expresses a beautiful space　

The Elimination of an uneven irradiation/yellow ring lets illuminated space to be presented more beautifully.
