Gls Single Dome Low Intensity Aviation Light

With LED-based solid-state lighting (SSL) technology revolutionizing the lighting industry, new opportunities for lighting products are appearing everywhere from residential to commercial to street lights. However, the dirty little secret of LED technology is that it presents a thermal management challenge that is significantly different, and hotter, than any challenge ever presented by legacy light bulbs. Conducting heat away from the LED junctions is a requisite for long product life and consistent lumen and color maintenance. There are many material and manufacturing choices for thermal management, and aluminum extrusions can serve in a broad set of applications.
Architects, lighting designers, and other specifiers are demanding fixtures and enclosures that offer great looks, options for both finish and color, as well as structural integrity. Design engineers are attempting to provide the above, while dealing with the thermal management issue. Lighting manufacturers want to deliver all of the above, but in cost-effective products.

Fig. 1.
The benefits of LEDs are well accepted at this point: higher-quality light, greater energy efficiency, and lower maintenance costs, thanks to the long life span of the bulbs. However, thermal management continues to be a challenge. The heat generated by LEDs is detrimental not only to the life of the bulb, but also to the quality of the light. Engineers are now challenged with developing products that not only look great, but also solve the thermal management problem.
The thermal challenge
The objective of thermal engineers is to remove the heat from the source and dissipate it into the surrounding atmosphere, as far from the electronics and as fast as possible. The lighting industry prefers to use passive thermal-management products such as heat sinks as opposed to active thermal-management techniques. Typically, active thermal management equates to the addition of a device to assist in moving air over the heat sink, often a fan. Moving air can increase the effectiveness of a heat sink or even enable the use of a smaller heat sink in some applications. However, active elements can increase cost, add noise, and/or decrease system reliability.
Engineers typically use the light-fixture or enclosure materials to assist in transferring the heat. Most materials have the ability to conduct heat, some better than others. This ability is also referred to as thermal conductivity and is measured in watts per meter kelvin (W/mk).
Different materials offer a broad range of thermal conductivity. For example, diamonds have a very high level (typically 2200 W/mK), but are obviously too expensive for use in lighting applications. Copper has a decent level of thermal conductivity (typically 390 W/mK), but has two significant drawbacks compared to aluminum — copper weighs approximately three times more than aluminum and typically costs up to five times as much. Aluminum doesn’t conduct heat quite as well (237 W/mk maximum), but offers the weight and cost advantages that are important in many SSL applications.
Computational fluid dynamics
To assist in determining the proper thermal management solution, engineers typically work with specialized software that models the products and their thermal characteristics. Computational fluid dynamics (CFD) is used to simulate the thermal conductivity of the product and finite element analysis (FEA) examines the structural integrity of the component. An example of CFD is shown in Fig. 1. There are numerous variables in each product that are dependent on product size, shape, and application (indoor versus outdoor, for example). By combining FEA and CFD along with the variables, it is possible to design the most cost-effective product that meets the needs of both the design engineer and thermal engineer.

Fig. 2.
Historically, aluminum has been the material of choice for thermal management applications in the lighting industry. The variable has been whether the aluminum is cast or extruded. LEDs, however, have resulted in new thermal challenges and also diversity in SSL product form factors that can require new thermal approaches. In response, the lighting industry has started to use thermo-plastics and graphite in certain thermal management applications.

As demand for LED (light emitting diode) luminaries continues to grow, new thermal management technologies are allowing manufacturers to produce LEDs that have higher light output and longer lifespan. LEDs offer many advantages including low energy consumption, long service life (bulbs can last up to 40,000 hours or more), and environmental safety (they contain no mercury). The disadvantages of LEDs, such as higher prices than incandescent or fluorescent lighting, will dissipate as new manufacturing techniques make LEDs less expensive to produce and better able to handle heat fluctuations. Thermal management is one of the most important aspects of successful LED systems design, according to the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy. LEDs convert only 20- to 30-percent of their electric power into visible light; the remainder is converted to heat that must be conducted from the LED die to the underlying circuit board and heat sinks. Excess heat can reduce LED light output and shorten lifespan. Therefore, managing thermal output to dissipate heat is crucial to maximizing the LED’s performance potential. A Thermal Substrate Alternative Currently, for high power/high brightness applications, the LED package or module is soldered to a metal-core printed circuit board (MCPCB), thermally enhanced PCB or a ceramic substrate, which is then bonded to a heat sink. Although this configuration is used widely in the LED industry, it does not offer the best method for managing heat conductivity and can be expensive to produce. MCPCBs and thermally enhanced PCBs offer good thermal performance but have limited design flexibility and can become expensive when high thermal performance is required due to additional costs for machining thermal vias and the high cost of expensive thermally conductive dielectric materials. Ceramic substrates are made from lower thermally conductive, but cheaper ceramics, such as alumina, or higher thermally conductive but very expensive ceramics like aluminum nitride. Overall, ceramic substrates are relatively more expensive than MCPCBs and thermally enhanced PCB substrates. As an alternative to the substrates discussed above, LED manufacturers are testing the concept of building circuits directly on aluminum substrates, which offer excellent thermal conductivity. Although the LED industry is interested in using aluminum due to its advantages, LED circuits built on aluminum require an insulation layer on the substrate. Now, advances in thick-film technology are allowing the LED industry to reap the benefits of using aluminum substrates. IAMS, an Insulated Aluminum Material Systems developed by Heraeus Materials Technology, a supplier of products for thermal management applications, is a low-temperature firing (less than 600°C), thick-film insulating system that can be printed and fired on aluminum substrates. The IAMS material set consists of dielectric pastes, conductors, solder masks, and resistors. All the materials are compatible with 3000, 4000, 5000 and 6000 series aluminum substrates. IAMS Advantages “IAMS is designed as an insulation system for aluminum substrates,” said Mitsuru Kondo, Global LED Project Manager for the Thick Film Materials Division of Heraeus. “Aluminum cannot handle temperature higher than 660°C, and standard thick-film products are ceramic-based and must be fired at very high temperatures of 800°C to 900°C. “Because the IAMS pastes can be fired at less than 600°C, the system is compatible with aluminum processing conditions,” Kondo explained. “Also, IAMS’ unique glass system minimizes bowing on aluminum while providing high dielectric breakdown strength and excellent thermal conductivity.” Most thick-film pastes have a CTE (Coefficient of Thermal Expansion) adjusted for use on high- temperature, low-CTE ceramic substrates. However, if you are using aluminum substrates, which have a very high CTE, and a paste designed for ceramics, the substrate will “bow” due to the differences in CTE. The CTE on IAMS is designed to match the CTE of the aluminum, minimizing any bowing.

The gallium nitride (GaN) based white light emitting diode (LED) luminaire system presents a pathway to enhance efficacy, functionality, and the possibility to cut down pollution from traditional lamps. Much effort has been done to improve its performance/price ratio to penetrate the market, including designing and optimizing the LED package structure. Multichips embedded on the aluminum core printed circuit boards (Al-PCB) architecture is one of the features of the LED package method, along with low thermal resistance, low price, and easier development compared with luminaire systems. However, the thermal resistance of the packaged LED varies with the stochastic parameters of the LED packing process, thus posing challenges in packing cost and reliability. In the present paper, the thermal uniformity of packaging the LED array embedded on Al-PCB technology is explored using the Bayesian probability theory. The stochastic thermal characteristics of Al-PCB are investigated by an active infrared imager, and its thermal time constant matrix-based probability is suggested to estimate uniformity. A package design procedure, involving multi-physical finite element simulation, Al-PCB infrared checking, and probability estimation, is proposed. Finally, a 12 LED array for MR-16 lamp is demonstrated. The results show that the thermal uniformity of Al-PCB plays a significant role in packaging multiple LED embedded on Al-PCB, which can be physically indicated by the thermal time constant matrix-based probability. The suggested package procedure sheds light on solving the cost-related thermal uniformity of the LED array. In addition, a proposal to further reduce cost by replacing Au wire with Ag bonding wire is not deemed to be possible based on scanning electron microscopy structure analysis.

5 Light control To obtain a better light control, the technology employs a mix of low beam, medium beam, and high beam lens control, generating more lumens in the target lighting zone, increasing pole spacing up to 8 times greater than the mounting height, and reducing glare. LOW BEAM MEDIUM BEAM HIGH BEAM High beam, medium beam, and low beam light management gives the Roadstar better light control and better lumen targeting. EXAMPLE: LE2 FULL CUT-OFF OPTICAL SYSTEM Spacing up to 6-8 times mounting height MEDIUM LOW More lumens / Less glare Roadstar Series 5

6 Superior performance Customize this luminaire with stunning precision to cast light only where you want light to be cast. It uses up to 50% less energy than traditional cobraheads but 100% pure dark-sky compliant performance. The Roadstar s LifeLED light engine generates light that is uniform in intensity, and Philips patented light stretching technology inside the LifeLED engine provides the widest possible pole spacing for a luminaire of its kind. The Roadstar incredible light control provides pole spacing up to 8 times its mounting height. This reduces the quantity of poles (thus luminaires) needed to illuminate any given project and allows any site to keep its existing infrastructure and simply upgrade its cobraheads to the Roadstar. To counter glare, the Roadstar provides unparalleled uniformity and intensity. This assures security on the road by not interfering with the vision of drivers, cyclists, and pedestrians. << >> SPACING UP TO 8 TIMES MOUNTING HEIGHT Less luminaires are needed to achieve the same uniformity and intensity of light. Target lumen The results of a controlled test comparing a typical 100HPS cobrahead with a 65W Roadstar clearly demonstrate the light control that is possible to achieve with this luminaire: same lumens in the target area using less power.

7 LifeLED lifespan With a light source that lasts well over 70,000 hours (over 16 years) and with extremely low maintenance needs, the Roadstar will deliver whatever is required of it, while asking very little in return. LM80 tests performed on the Roadstar clearly demonstrate that it not only meets criteria, it greatly surpasses them, giving it a lifespan that well exceeds the 70,000 hour mark thanks to better thermal management and lower current needs. The lifespan of an LED luminaire is measured using lumen depreciation. When the LEDs in an LED light engine reach 30% lumen depreciation, they should be replaced. However, since the lumen depreciation in the LifeLED engine happens slower thanks to better thermal management (65 C), better junction temperature management (82 C), and lower current usage (570mA), when the Roadstar reaches 70,000 hours of use, its lumen depreciation will still be well under 30%.
