In November 2013, Karvin Power Systems upgraded its series of LED streetlights, ranging from 12 W to 120 W. These offer several features, including an aluminium die-cast body with an IP-65 enclosure, an accurate light distribution design, high luminance, illuminance uniformity, a long life of up to 50,000 hours with a CRI>75, and a high quality driver with APFC>0.95 pf and THD<10 per cent. These lights are traditionally designed and integrated with LEDs and lenses.
Dimmable LED driver
In December 2013, Supertex introduced the PS30, a constant frequency (67 kHz), constant duty cycle LED driver optimised for dimmable offline LED bulb/tube applications, providing high power factor correction (PFC). The PS30 is intended to drive a single switch, single inductor power converter (flyback for isolated version and buck-boost for non-isolated version) directly from an AC line, 110 V or 220 V, for power levels up to 20 W. The PS30DB1 demo board provides a 6.3W design solution, achieving 93 per cent PFC and greater than 81 per cent efficiency with ±4 per cent current accuracy. It can be modified for other power levels up to 20 W. The PS30 offers smooth dimming to extinction for a wide variety of leading edge dimmers, trailing edge dimmers, and dimmers with microprocessor controls.
Outdoor stake light bracket
In November 2013, GlacialLight introduced an outdoor stake light bracket. This simple and sturdy light bracket lets you install any of GlacialLight’s outdoor lighting fixtures easily and conveniently in almost any outdoor area, including plazas, parks, gardens and lawns. The aluminium construction makes it light yet strong and resistant to corrosion. Placing and repositioning the light is simplified. Besides, vertical and horizontal rotational adjustments of the light are possible with the bracket. The outdoor stake light bracket is compatible with GL-FL12, GL-FL30-V2 and GL-FL60 floodlights.
