the prerequisites change in the course of time

The advantages of LED-modules over the firmly fitted individual LED are also made apparent by the Siteco Streetlight10 LED street lighting series. By separating the luminaire and the module, modules for different purposes of use, such as zebra crossings and surface illumination, can be integrated into the same luminaire. This lowers manufacturing and developing costs and thus has a positive impact on the marketability of the product. Should the prerequisites change in the course of time, the luminaires can easily be retrofitted to different and more high-performance LED-modules, thanks to their modular construction. Hence, for municipalities and operators of outside facilities, Street light10 offers a highly adaptable, cost-efficient and future-oriented approach on the road to LED-street lighting.

The OSRAM Encelium lighting management system, which will be introduced in Europe at Light+Building, demonstrates impressively how up to 75% of energy in offices, industrial buildings and functional buildings such as hospitals or other public buildings can be saved. This is made possible by combining six different strategies, all of which are aimed at saving energy. Building operators are able to steer and monitor the system worldwide via the Internet, using unique software with 3D images. What is more, office workers are able to adjust light levels at their individual workplaces. When used in connection with the latest generation of OSRAM electronic control gears (in accordance with the DALI standard), the Encelium system is able to record and depict the energy consumption of the lighting in real-time. The software identifies optimization potential, in addition to allowing pin-pointed intervention. The result: more cost-efficient and flexible electricity tariffs can be used. Furthermore, by applying a specific interface, Encelium can also be incorporated into the building management system.

Lighting Science Group's PROLIFIC Series DBR and LSR4 street lights, complete with wildlife guards, were used to light of the streets of Pleasant Prairie. The DBR luminaires are compatible with smart grid services, remote monitoring capabilities, dimming, midnight dimming, and occupancy sensors; while the LSR4 fixtures offer a full cutoff optic that meets dark sky requirements.

The Company's PROLIFIC Series street lights are the perfect one-to-one replacement for HPS street lights—easy to install, high lumen output, maintenance-free operation, long-lasting, and have outstanding energy savings.  The PROLIFIC Series LED technology eliminates costly re-lamping and re-ballasting of HPS street lights and direct line wiring is used in place of starters or capacitors to eliminate traditional maintenance issues.

LED street lighting is an optimal solution for municipalities across the country

known for most of the 20th Century as the Oil Capital of the World, is now leading the way with new energy efficient alternatives. Thanks to a highly successful collaboration between the City of Tulsa, U.S.-based luminaire manufacturer, Amerlux, and U.S.-based lightsource manufacturer, Bridgelux, modern, energy-efficient LED lighting are part of the restoration of Tulsa’s historic Brady district.  About 200 Amerlux outdoor luminaires based on Bridgelux LED arrays are planned to illuminate the walkways around the new Driller Stadium and park. Sixty-four were installed in 2011 with the remaining street lights slated for installation this year. The new LED lighting is anticipated, in the long run, to save the City of Tulsa thousands of dollars in reduced energy and maintenance costs, compared to the conventional High Intensity Discharge (HID) streetlights used in other areas of the city.

“The collaboration between the City and its lighting manufacturer and supplier delivered a flexible, energy- and cost-efficient solution that significantly improved the quality and longevity of Tulsa’s outdoor lighting,” said Paul Strizek, planning and contracts manager for the City of Tulsa. “Together we delivered on the City’s commitment to reduce our energy use, increase sustainability and offer our citizens a better quality of light.”

Featuring industry-leading Bridgelux ES LED arrays, the Amerlux D142 and D154 Series decorative downlight allows for a variety of optical configurations, enabling the systems to be optimized for a customer's unique needs such as application requirements and light output. This helps to ensure that light levels and light quality meet the application requirements for a particular environment. Moreover, the Amerlux D142 and D154 downlights deliver large lumen packages of up to 7600 and 5000 lumens respectively, making it an ideal replacement for HID luminaires.

LED street lighting is an optimal solution for municipalities across the country, delivering immediate savings from lower energy costs and reduced maintenance costs. Further, high quality LED lighting increases the visibility and visual attraction of storefronts, restaurants and other hospitality and commercial environments, as demonstrated in the white paper published by LED Roadway Lighting.

 Reporters recently learned from the Shenzhen Municipal Development and Reform Commission that Shenzhen Development and Reform Commission, Shenzhen Municipal Trade and Industry and Information Technology Commission, Shenzhen Finance Committee jointly issued the notice as “the first step plan of Shenzhen new energy industry development funds for supporting the industry in 2011”. Shenzhen Solar Semiconductor Lighting Engineering Laboratory, which was established by Spark, has been fully certified by the experts’ team. It is the first solar semiconductor lighting laboratory in LED lighting industry.

It contains a charger to store energy in a supercap

ST hopes to change that with its new STCF04 multifunction chip, which it says can control flash power up to 40W, compared to perhaps 2W for typical LED flashes today.

The key is the chip's ability to control the charging and discharging of a supercapacitor, which it uses to gradually store energy from the phone's battery and then deliver it to the LED in a short burst.

ST's chip, just 3 millimeters square, will add $2 or less to the cost of a cell phone, it said.

It contains a charger to store energy in a supercap, and a driver for an external transistor used to deliver 40 watts or more of peak power from the supercapacitor to a bank of LEDs. It also contains a temperature sensor to detect when the LEDs are in danger of overheating -- useful if they are being used as a torch rather than a flash; a light sensor for setting the exposure and flash intensity, and a driver for an auxiliary LED used either as a privacy indicator (you're on camera) or perhaps to help autofocus systems in low light.

The small size combined with powerful output allows for a previously unobtainable

LED Engin, Inc., a leader in high lumen density LED products, announces a family of metal-core printed circuit boards (MCPCBs) with integral connectors that eliminate soldering during the assembly of LED fixtures. The poke-home connectors, which accept 18-24 AWG wires, offer quick, solderless assembly of fixtures and can eliminate the need for OEMs to use sub-contractors because the work can be taken in-house.

The boards utilize a common 50mm footprint for both the LuxiGen LZC 12 die and LZP 24 die series of high flux density emitters, helping OEMs to standardize fixture designs around a single form factor. The low thermal resistance MCPCBs mean that heat is effectively conducted away from the LEDs, so that the emitters can be driven up to 1000mA / die to maximize flux density without adversely affecting operating life or reliability. The boards feature mounting holes for LuxiGen TIR lens-holder legs for easy integration with secondary optics. There are mounting-screw cutouts to facilitate easy attachment of a heatsink, further simplifying the assembly process. The boards include one connector for the LED and one for an on-board thermistor to be used with common constant current sources with thermal feedback option. Materials and components are selected to meet UL requirements.

LED Engin, based in California's Silicon Valley, specializes in ultra-bright, ultra-compact solid state lighting solutions that allow designers and engineers the freedom to create uncompromised yet energy efficient lighting experiences. Their LuxiGen(TM) Platform - an emitter and lens combination or integration module solution, delivers superior flexibility in light output, ranging from 3W to 90W, a wide spectrum of available colors including whites, multi-color and UV, and the ability to deliver upwards of 5,000 high quality lumens to a target. The small size combined with powerful output allows for a previously unobtainable freedom of design wherever high flux density, directional light is required.

easily interface the light source with camera systems

The XLM Plus operates on 12V DC or 24V DC input. Light intensity can be varied by constant current and/or by an internal or external Pulse Width Modulation (PWM) signal.  PWM enables users to control light output while maintaining a stable Correlated Color Temperature.  In addition, the Module’s RS-232 and auxiliary interfaces allow users to control the light source from a remote location and easily interface the light source with camera systems.  Other product features include integrated thermal monitoring, variable speed fan, and over-temp protection.  These features increase patient safety and aid in ensuring a long operational life, upon integration into a medical OEM’s finished device.

The Model Number for the XLM Plus LED Fiber Optic Light Module with Electronics is OTFI-0275.  Excelitas’ XLM Series LED Fiber Optic Light Module without Electronics is Model Number, OTFI-0250.  More information on the XLM Series of LED Fiber Optic Light Modules for Medical OEMs can be found on the Excelitas website.
