Seoul Semiconductor has begun mass production of new products with a luminous efficiency of 210 lm/W (350 mA). The Wicop module is composed of an LED chip and phosphor only, and does not require packaging for wrapping the chip, such as frames and gold wires, etc. According to the firm, the new Y22 LED is also more than 17% more efficient than a CSP (chip scale package), which is similar in appearance.
Wicop LEDs are well suited as light sources for applications such as wall washers or floodlights in the architectural space, and lighting in warehouses or production sites in the industrial arena. Outdoors they can be used for street lighting, in tunnels or for the illumination of stadiums, harbours, airports or railway stations, as well as for security applications.
Also available are reference modules for the Wicop Y19, Y22 and Y22P LEDs. The Y19 module consists of four clusters of 2 x 2 LEDs with a combined typical flux of 4650 lumens, while the Y22 and Y22P modules achieve 1268 lumens with four single LEDs each. They all feature a colour rendering index (CRI) of 70 and a correlated colour temperature (CCT) of 4000 K.
All modules are tailored to common customer needs and follow the outlines given in book 15 of the Zhaga specification, which defines the location and pitch of the LEDs and the position and size of the alignment holes for optical lenses. The boards feature standard power connectors and are easy to assemble and easy to use together with commercially available lenses, like the new Wilma lens-array from LEDiL.
