Encapsulation is generally adopted in packaging of lamp-LEDs. The encapsulation procedure is to pour liquid epoxy into the LED moulding chamber first, and then insert the LED bracket that has undergone the press welding, then put the mould into the oven, and the LED gets shaped when the epoxy solidifies. The procedure of encapsulation sounds rather simple, while the following points should be paid attention to:

Philips Lumec has been chosen by the Eastern Band of Cherokee Indians of western North Carolina to light their downtown streetscapes with their environmentally responsible LED lighting solutions.

Following the launch of the VEX 130, Vexica, a UK based provider of SSL solutions, has announced the launch of the VEX 70. The VEX 70 is a small light engine suitable for indoor applications. The high power LED light engine uses the company’s patent pending technology at the heart of the product. The VEX 70 delivers between 900 and 1350 lumens (colour temperature dependent) of LED light in a form factor that offers unrivalled lumen level and homogeneous light output.

Unlike conventional LED strips which emit isolated, lined up spots of light, the M-TUBE from MENTOR is the first LED light guide system that dissipitates light perfectly homogeneous to the environment. The principle of the targeted light reflection along a crystal clear light guide makes this possible: The light is simply fed in at the side of two LED housings and is dissipitated in a targeted way to the environment along an imprinted reflector line inside the bar.

Cree, Inc. announces that Fairview, Texas, has joined the LED City® initiative, an international program that promotes the deployment of energy-efficient LED lighting. The newly constructed, four-lane Fairview Parkway, designed specifically to be lit with LEDs, features 82 LED street lights from EvoLucia, a division of Sunovia Energy Technologies, Inc.

Wavien, Inc. today announces that its patented Premien LED projector technology produces output in excess of 200 lumens using a single white, 50 W LED. The output efficiency of Premien technology, which is currently available for portable projector applications, is up to two times higher than the competing LED technologies. Wavien continues to optimize the system performance of projectors using Premien technology and expects that next-generation performance will increase to over 300 lumens.

Researchers at the University of Connecticut have made a new material that emits bright white light by adding fluorescent dyes to DNA and then spinning the DNA strands into nanofibers, according to a paper published online in the journal Angewandte Chemie. The researchers create white-light-emitting devices by coating ultraviolet (UV) light-emitting diodes (LEDs) with the material. They are even able to fine-tune the white color tone to make it warm or cold.

The City of Danville is likely to become the first LED city in Virginia, the United States. City officials say that the city has received a 50 thousand dollar grant for it to switch to new LED lights in different parts of the city. LEDs use less energy, last longer and are more environmentally friendly. So far, they've been installed at the water plant, and at the adult detention center.

LSI Industries Inc. (Nasdaq:LYTS) Wednesday announced it has completed the acquisition of AdL Technology and related companies (AdL Engineering and Kelmilfeen), privately owned and based in Columbus, Ohio. Consideration for the asset purchase of these businesses consisted of 2,469,676 shares of LSI's unregistered common stock, cash of $1,328,000, and assumed indebtedness of $3,526,000. The management team of AdL has entered into employment agreements and will continue in their current positions to manage the business for LSI.

Enfis Group Plc. (LSE: ENF), an innovator of intelligent LED lighting systems and technologies, today announced the launch of their new Innovate Series of LED arrays for use in myriad street lighting applications throughout North America.

In the picture below, you will notice the warm glow that shows in the sky deep into the night. This happens in every city. Scientists call this phenomenon – sky glow!

Since the first light bulb was invented in the 1800’s new lamp technology has evolved. When the fluorescent tube was invented in 1929, sales of traditional light bulbs plummeted, and then in the 1970’s along came the compact fluorescent, since then new variations have evolved, sales of the former types have virtually disappeared, but the fundamental lamp design has remained unchanged, using a heating element to ignite gases and produce light. The use of a heating element results in energy being wasted as heat as opposed to generating light.

Supertex, Inc. (NasdaqGS: SUPX) recently introduced the HV9918, a buck-mode LED driver IC with hysteretic current control and high-side current sensing. It is ideal for a variety of solid-state lighting applications, such as low voltage industrial and architectural LED lighting, signage or decorative lighting, indicator or emergency lighting, as well as a general purpose constant current source.
