Features
 
Original Kyocera LED package design utilizes Kyocera core ceramic technology
■ Kyocera’s ceramic package facilitates high heat dissipation and high-density LED mounting
Kyocera is a global manufacturer of proprietary ceramic materials that offer outstanding thermal conductivity. These materials facilitate high-performance LED packages that allow high-density LED mounting with excellent heat dissipation.

■ Thermally-conductive adhesive enhance heat dissipation further
Ceramic packages with thermally-conductive adhesive provide even higher heat dissipation and reliability in our LED packaging while also greatly reducing energy consumption.

Fig. Comparison of heat resistance with different products
The total heat-transfer resistance of Kyocera’s LED packages is about 1/5 that of Alumina-based LED packages due to the thermally-conductive adhesive and thermal properties of Kyocera’s proprietary ceramic.
* Research by Kyocera as of July 2015

(1) Comparison of irradiation doses at equal power consumption:
Irradiation dose of G3 Series is 14% higher than that of Al-based substrate products.
(2) Comparison of current value at equal irradiation dose:
Power consumption of G3 Series is 20% lower than that of Al-based substrate products.

Optical simulation technology
Kyocera employs simulation technology to optimize characteristics such as irradiation, focal length and light uniformity. These simulations allow Kyocera to optimize product performance by adjusting both the optical arrangement and the shape of the light-condensing lenses, imaging lenses and reflectors.

■ Working distance: 30 mm or longer
Kyocera has achieved maximum irradiation capabilities at different focal lengths by optimizing the positioning of lenses and LED elements with our optical simulation technology.
This allows the G4 Series to be installed at the chain delivery phase of a sheet-fed offset printer. The G4 Series is also suitable for applications requiring high irradiation and/or long working distances.
