Non-imaging optical system

With LED light sources using an imaging system, LED image formation occurs on the incidence end surface of a light guide and illumination distribution is uneven due to an aberration as seen in image (b) above. On the other hand, U-Technology’s non-imaging optical system can reproduce the circle shape of the light guide and results in even illumination distribution as seen in (a) above.

High illuminance

Light emitted from LEDs based on our proprietary optical system is condensed onto the light guide end surface to achieve higher and more even illuminance, which makes it possible to replace metal halide lights.

Industry's best brightness level - 130% of metal halide light*

* Based on U-Technology’s research
*φ12 straight type (WD=100)
*The values are observed illuminance values, not guaranteed values.

Feedback function (BTO)

Our proprietary technology maintains a constant light output regardless of room temperature and time.

•Less need for illuminance management and device initialization
•Stable operation of manufacturing line

Three different standard external control modes

•Serial communication: RS-232C (240-step)
•Digital: 8-bit digital control (240-step)
•Analog: 0-5V (960-step)
(Selectable using the mode selection switch)

ON/OFF switching

Lighting can be switched ON/OFF.
•Lighting is turned ON for inspection and OFF for downtime to save energy.
•To keep lighting ON during device adjustment work, lighting mode can be reversed easily using the mode selector switch.
