LEDs Enable Visual Confirmation Of Data Traffic And Connectivity
LEDtronics Inc.
(800) 579-4875; www.ledtronics.com

Members of a line of pc-board LED indicators for RJ45 ports feature a slim profile. The devices enable visual confirmation of data traffic and network connectivity. They also ensure signal integrity on data/telecommunication equipment such as Ethernet hubs, bridges, routers, and modems.

According to the company, the black UL940V0-compliant housing takes up minimal space. Also, coplanar design facilitates alignment and arrayed configurations. An advanced optical-grade epoxy produces bright and smooth illumination. While diffused lenses are standard, clear lenses are available. Optional configurations include one LED or two LEDs. Rectangular and domed shapes are available. Domed indicators measure 3 mm (T1). Rectangular indicators are available with measurements of 1.8 by 3.8 mm or 2 by 5 mm. While single-colored LEDs are offered in red, green, and yellow, bi-colored combinations include red/green and yellow/green. Depending upon factory approval, orange and pure green may be ordered for either configuration.

The RJ45 pc-board LEDs are available now. In 1000-unit quantities, they cost between $0.55 and $0.88 each, depending on the LED color and size.

Lamp Displays Bright, High-Quality Pictures With Wide Viewing Angles

The Planon lamp is a light source capable of displaying high-quality pictures with wide viewing and illumination angles. It features constant luminance from center to edge. The Planon boasts an extremely long lamp life of up to 100,000 hours. Measuring less than 10 mm thick, this lamp is mercury-free. This feature eliminates warm-up time. Also, the output is virtually independent of ambient temperature.

The Planon source generates light using a xenon excimer discharge. When a suitable voltage is applied to the electrode system of the discharge lamp, xenon gas is excited in the lamp cavity. When the excimers decay, short-wave ultraviolet radiation is generated and converted into visible light by a phosphor coating. Ultraviolet photon formation is achieved by adding an electrically insulating barrier over the electrodes and creating special voltage-input patterns. According to the company, the Planon enables the improvement of existing systems with regard to luminance and service life.

LEDs Deliver Twice The Brightness Of Conventional Bullet-Type LEDs

The Double Reflection (DR) LED directs all light forward in a consistent, intense light beam. According to the company, this LED uses proprietary optical technology to deliver at least twice the brightness of conventional bullet-type LEDs. It also lowers power consumption and energy costs. In a high-mounted automobile brake light, 20 DR LEDs deliver as much as 40 conventional LEDs. These devices also function for solar-powered roadway center-line lighting, perimeter guardrail lighting, commercial exit lighting, and battery backup lighting.

Optionally, the reflective surface within the LED can be designed asymmetrically to reflect light in a direction other than straight ahead. By focusing beams into a concentrated beam, a traffic signal can deliver as much brightness as 300 conventional LEDs while using only 100 DR LEDs. Applications for DR LEDs include automotive, traffic signals, perimeter lighting, and commercial lighting. In these applications, the devices achieve greater energy savings while increasing light intensity.
