BOARD ASSEMBLY
IR Spotlight LED Unit ~HIGH POWER Mirror Type LED~
Infrared Spot Light LED Unit can realize an excellent beam light with extremely high radiant intensity (±4o). Alpha-One successfully developed it with the excellent and unique optical technology by combining the high power mirror type LED and the Fresnel lens. It is suitable and more convenient for light source for a long-distance irradiation such as surveillance system (IR illuminator for CCD cameras).

Output-Feedback type LED: AL130K
For the applications with a highly stabilized light source for precise optical systems, an LED and a photodiode are combined and packaged together.
The photodiode defects changes in the LED light intensity and feeds this changes to an external power supply circuit for the LED. The circuit increases and decreases the voltage (or current) to maintain a stable intensity
White LED backlight module
It can emit perfectly without any uneven light thanks to its excellent lens effect and suitable for the backlight of signboard and indirect illumination. Compared with the traditional fluorescent lamps, LED module can be realized to curtail the total running cost to maintain the whole lighting units due to the lower electric consumption by 1/3 and the longer lifetime of about 60000Hrs. It is supplied as a string which contains 50 LED modules connected with parallel circuit.
