the color always varies even if the products are produced in the same lot

PowerSecure’s plan to exercise its option to increase its ownership of EfficientLights from 67% to 100% recognizes the highly successful results EfficientLights has posted to date, its strong backlog of orders for 2010, and its strong prospects for future growth. The transaction is expected to be accretive, and will involve the issuance of PowerSecure common shares in exchange for the remaining one-third minority interest in EfficientLights. The number of shares to be issued in exchange for the remaining one-third interest will be 1,000,000 shares, provided that if the average closing price of the PowerSecure shares over the ten days preceding the transaction is less than $10.00 per share, then the number of shares delivered increases to maintain a transaction value of $10.0 million. After the exercise of the EfficientLights option, EfficientLights will become a wholly-owned subsidiary and the Company will realize 100% of the EfficientLights profit, and will no longer reduce its net income for the amount attributable to the EfficientLights non-controlling interest.

Through use of “3-Step MacAdam ellipses” as a chromaticity control standard the necessary reduction in the variation in chromaticity is accomplished.
White LEDs are well-known in various fields such as for LCD TV’s backlights or lighting and they require strict color control of the chromaticity range, especially in white led highbay light for general lighting. Usually, the products need to be ranked and sorted according to the requirements before shipment, as the color always varies even if the products are produced in the same lot.

Since the chromaticity of a white LED is determined by a combination of many elements configuring the product such as a light-emitting device, phosphor, and encapsulation resin, a complicated process control is also needed to control those elements. We developed Surface Mount LED chips in 1983, and since then we have brought out a wide variety of products as a leading manufacturer of LED packages. Using basic studies and innovations of our accumulated high-precision processing technology and manufacturing technology has allowed us to finally achieve mass production with the chromaticity standard of about a ninth of the conventional chromaticity range by controlling the deviation from specific chromaticity coordinates and “elaborating” the products.

LED recessed downlighting options for general lighting in commercial

Cooper Lighting, a division of Cooper Industries plc (NYSE: CBE), has expanded its Halo LED H7 Collection offering additional choices in LED color temperatures and higher lumen options. The 6” LED downlight product line expansion–from the original Halo LED 600 Series–now includes the Halo LED 900 Series and Halo LED 1200 Series, offering a wide and versatile selection of energy-efficient LED recessed downlighting options for general lighting in commercial, retail, institutional and residential applications. Designed for new construction projects or to retrofit existing 6” nominal compatible housings (with an Edison screw base adapter included with the module), the Halo LED H7 Collection features excellent color rendering (80 CRI) and offers the industry’s widest selection of color temperatures (2700K, 3000K, 3500K and 4000K). The superior optical design yields productive beam lumens providing smooth, even illumination, excellent cutoff and extremely low glare. Consuming less than 15W, ...

Semiconductor lighting industry in Shenzhen develops rapidly in recent years

Orion’s LED fixture, designed to perform at temperatures as low as -20 degrees Fahrenheit, has been retrofitted in more than 3 million square feet of freezer and cold-storage space in facilities across the nation in the past several months. Companies with Orion LED technology in their facilities include US Foods, Sysco, Americold, and Save-A-Lot. The three approved Orion LED fixture models vary based on application-specific lens configuration. Orion’s LED fixtures are designed to replace traditional high intensity discharge and T8 and T5 fluorescent fixtures. Orion’s LED fixtures use 123 watts compared to 400-watt HIDs and 298-watt fluorescents. According to its Web site, the DLC is a collaboration of utility companies and regional energy efficiency organizations committed to raising awareness of the benefits of efficient lighting in commercial buildings. In order to be included on the DLC’s QPL, a product must meet or exceed specific industry standards. QPL inclusion is required for c...

Entertainment applications will adopt the new LEDs

The number and breadth of applications that require amber LEDs is tremendous,” said Frank Harder, VP of Product Marketing at Philips Lumileds. “Markets including automotive, entertainment, roadway, signaling, and many others use amber LEDs. With better efficiency and more light output, LUXEON Rebel PC amber makes it that much easier to reduce energy consumption with an environmentally friendly product.lamps to LEDs because they didn’t produce enough light and couldn’t operate effectively at higher temperatures. With the advances provided by LUXEON Rebel PC Amber, yellow traffic signals will be converted, warning lights and beacons on vehicles and obstructions will switch and entertainment applications will adopt the new LEDs. numbers of amber LEDs. With LUXEON Rebel PC Amber, manufacturers will be able to use fewer LEDs and lower other component costs because of the improved light output and particularly the stable color over temperature, something that has been problematic for many ...
