EVERLIGHT

LEDs, optocouplers, infrared devices and optoelectronic components

About the manufacturer

EVERLIGHT Electronics Co., Ltd. is a Taiwanese optoelectronics manufacturer founded in 1983. The company specializes in LEDs and other light-based components used for indication, illumination, transmission and sensing.

Its portfolio includes SMD and through-hole LEDs, high-power LEDs, lighting modules, LED displays, optocouplers, phototransistors, photodiodes and infrared components. EVERLIGHT serves consumer electronics, industrial equipment, automotive applications and professional lighting.

The company operates its own R&D and manufacturing resources, with strong emphasis on repeatable parameters, long operating life and stable performance in volume production.

A broad selection of packages, colors, viewing angles and electrical parameters allows EVERLIGHT parts to be used both as simple indicators and as light sources or optical components in more demanding designs.

For design engineers, the breadth of the range makes it possible to keep several optoelectronic functions within one supplier family, from visible indication to infrared transmission and isolated feedback. Package choice can therefore be coordinated with PCB density, optical geometry and production method.

Applications

EVERLIGHT components are used wherever a design requires optical indication, illumination, light transmission, sensing or galvanic signal isolation.

Consumer electronics – status indication, backlighting and user-interface lighting.
Industrial automation – indication, optical sensing and galvanic isolation.
LED lighting – luminaires, modules and professional light sources.
Automotive electronics – interior lighting, signaling and optoelectronic functions.
Communication equipment – indicator LEDs and infrared components.
Measurement equipment – photodiodes, phototransistors and optical sensing elements.
Power supplies and control systems – optocouplers for isolated feedback.
Human-machine interfaces – illuminated keys, status icons and panel indicators.
Optical feedback and sensing – emitter/detector pairs for presence, position and reflective sensing.

EVERLIGHT products available from Maritex

The EVERLIGHT range available from Maritex includes a broad selection of optoelectronic components for electronic devices, signaling systems and lighting projects. LEDs in multiple package and mounting options form one of the largest product groups.

Available product groups include:

Photodiodes and phototransistors for sensing circuits.
Optocouplers for isolated signal transfer and feedback loops.
SMD LEDs.
Standard through-hole LEDs.
White and colored LEDs.
LEDs for indication and backlighting.
LED display components and modules.
Optocouplers and optoelectronic devices.
Infrared and photodetection components.

The range includes families such as 16-213 and 26-21 as well as parts such as A694B/SURSYG/S530-A3. Available variants differ in color, viewing angle, operating current, package and mounting method.

When selecting an LED or optoelectronic device, consider wavelength or color, luminous intensity, viewing angle, forward current and voltage, thermal conditions and mounting technology. For optocouplers and detectors, also verify isolation voltage, current-transfer ratio or photosensitivity, switching speed and package creepage requirements in addition to the optical parameters of LEDs.
