C-TICK certificate of LED power supplies

September 26, 2011, Buddy Lighting's dimmable and non dimmable constant current LED power supply series got the Australia C-Tick certificate successfully. The new power supply series mainly used for LED down lights etc as exterior power supply.
The dimmable PS series can be used with trailing edge, leading edge and universal dimmer. during the dimming, no flickering, no buzzing, dimming smoothly. It can comply with the most of dimmer in the worldwide.

Color mixing enables high CRI and high LED efficacy

When amber LEDs are combined with phosphor-converted blue LEDs, warm white light with both high CRI and high efficacy can be attained simultaneously.
Marc Dyble, product marketing manager of SSL products at Osram Opto Semiconductors discussed the potential of mixing monochromatic LEDs with phosphor-converted LEDs (PC-LEDs) to achieve high CRI and high efficacy at the same time. He presented this approach at the LED Show in Las Vegas last week. Dyble stated that color mixing, marketed as Brilliant Mix by Osram Opto, provides an alternative method of achieving high CRI for applications such as high-end retail. He explained that typical approach today to attaining warm/neutral white light with LEDs and high CRI (>90) comes with a penalty of luminaire efficacy in the 75 lm/W range. Instead, if a combination of monochromatic LEDs (amber) are placed alongside phosphor-converted blue LEDs either in a multichip chip-on-board or multichip array, luminaire efficacy in the 90 lm/W range (up to 110 lm/W at the LED level) can be attained at 2700K.

Dyble noted that there are some caveats to taking this approach. For instance, an optical mixing chamber may be required to obtain the necessary color consistency. In addition, the correlated color temperature (CCT) over temperature may vary. To improve stability, light and temperature sensors can be installed and compensation circuitry can be implemented.
However, Dyble contends that a color mixing approach should definitely prove better than methods that overdrive the LEDs and lead to early luminaire failure. In addition, from a user standpoint a tradeoff can be made between efficiency and color rendering by adjusting the monochromatic to PC-LED driving ratio. “One of the reasons we’ve been able to do this is because we’ve been able to linearize the efficiency of monochromatic LEDs,” said Dyble.
He added that Osram Opto and Cree have cross-licensing agreements in the area of color mixing.

Cooper Lighting launches sleek line of outdoor luminaires

The Navion LED luminaire is offered in various lumen and optical packages to meet the output and light distribution of different street and area lighting applications.
Cooper Lighting has added the new Navion LED luminaire to its line of Lumark LED outdoor area, site and roadway lighting fixtures. The Navion luminaire's application-specific design allows lumen output and energy consumption to be configured to fit the lighting needs various applications, from single fixture to large office parking lots and roadway lighting. Energy savings is 30-70% over high-intensity discharge (HID) fixtures.

The luminaire's size and construction is scaled to the specific lumen package in five configurations from 3600 to 22,000 lm, or HID equivalents from 70W HPS up to 400W MH. The Navion luminaire features a 4000K color temperature and CRI of 70, with an optional 6000K (70 CRI) and 3000K (80 CRI) available. Rated lifetime is 60,000 hours at 90% lumen maintenance (16 yr at 10 hr/day).
The luminaire uses Cooper Lighting’s AccuLED optics system to achieve optical efficiency as high as 95%, while eliminating uplight, glare, obtrusive spill light and overlit hot spots. The user selects from ten optical packages.
With its die-cast aluminum construction and durable powder-coat finish, the luminaire is designed to withstand harsh environments over an operating range of -40[deg]C to 40[deg]C (50[deg]C optional package). Other features include tool-less door entry and quick electrical disconnects. Installation is performed with simple tools. The fixture is 3G vibration rated and comes standard with 10kV dual-mode surge protection
