An LED is what’s called a “solid-state lighting” technology, or SSL. Inorganic LEDs are bright and long-lasting, but the expense of manufacturing them has led to them being used mainly in niche applications such as billboard-size displays for sports arenas. What’s more, the manufacturing process for making inorganic LED displays is complex, because each LED must be individually cut and placed, says John Rogers, a materials science professor in the Beckman Institute at the University of Illinois at Urbana-Champaign. So display manufacturers have turned to organic materials, which can be printed and are cheaper. While LED-based lighting systems are attractive because of their low energy consumption, they remain expensive. The new printing process, developed by Rogers and described today in the journal Science, could bring down the cost of inorganic LEDs because it would require less material and simpler manufacturing techniques.
Like most products, LED Lights have varying qualities. Unfortunately for the consumer, LEDs are still so new most people don’t know how to determine if they’re buying low quality LEDs or a high quality LEDs. The low-quality LEDs will work – it just won’t run as efficiently, last as long, and may not have the light color or brightness that is ideal for your space and how you use it. These are key factors in loving or hating your LED Lights. Most households LED bulbs follow dimension guidelines for the familiar A19-shaped bulb. Some have a bulky, space-age-looking heat sink; others incorporate this necessary part more elegantly into the engineering. So-called snow-cone designs have a heat sink that takes up the entire lower half of the bulb. These emit directional light only, which is acceptable in pendant fixtures but throws unwanted shadows when installing in, for example, a table lamp with a shade. For that you’ll need an omnidirectional bulb, so check the packaging before you buy. Ready for complete adoption? You’ll find LEDs in floodlights, spotlights, and recessed-lighting formats, as well as in designer formats such as the flat panels of the Pixi system.
LEDs are made in different packages for different applications. A single or a few LED junctions may be packed in one miniature device for use as an indicator or pilot lamp. An LED array may include controlling circuits within the same package, which may range from a simple resistor, blinking or color changing control, or an addressable controller for RGB devices. Higher-powered white-emitting devices will be mounted on heat sinks and will be used for illumination. Alphanumeric displays in dot matrix or bar formats are widely available. Special packages permit connection of LEDs to optical fibers for high-speed data communication links.
The LED light is seen in such devices as microwave ovens, stereos, watches, remote controls, and even vehicle control switches. However, recently they have been developed for such practical uses as Christmas lights, neon lights, and even swimming pool lights. LED lights have a beautiful and brilliant array of color availability without sacrificing any of the quality of light that comes from other, inferior light sources. In addition, they use an extremely lower amount of energy to operate. They are quickly becoming a favorite among many people.
We also offer a premium automotive lighting solution line-up. With the utilization of ceramic substrate technology, our products deliver highly reliable performance through low thermal resistance, and deliver diverse color options including white, amber, allnGaP red led car lights and bi-color. Additionally, exceptionally compact 1mm x 1mm LED chips accomplish a sleek design with uniform light, significantly improving any driving experience through individually addressable multi-LEDs actualizing the Adaptive Driving Beam (ADB) solution.
