Beampro Technology Co Ltd, a Taiwan-based auto parts manufacturer, showed a microlens that increases the brightness of LED lamps of cars, two-wheeled vehicles, etc.

The microlens, "Cat's Pupil," was exhibited at 2015 Taipei AMPA & AutoTronics Taipei, a trade show on auto parts, which runs from April 8 to 11, 2015, at the Taipei World Trade Center in Taipei.

The microlens reduces diffusion of light by narrowing down the orientation of the light of an LED chip. Compared with LED lamps that orientate light with a reflector, it can reduce power consumption up to about 1/3, Beampro Technology said.

With the Cat's Pupil, it becomes possible to effectively use more than 95% of light emitted from an LED chip, realizing a total efficiency that is more than 100% higher than that of a reflective LED. The microlens is made of reinforced polycarbonate (PC). The LED chip is a product of Cree Inc.

The diameter of the lens is 7mm. A 1W LED chip is used for it. It can be used for various applications such as fog lamps, searchlights, the headlamps of cars and two-wheeled vehicles (low and high beams), etc. The product was given the Gold Award at 2015 Taipei AMPA & AutoTronics Taipei.
