LED indication products and solutions facilitate machine to human communication. Indication refers to the use of a light source that is to be viewed directly as a self-luminous object, such as in signs, signals, and indicator lights on electronic equipment. LED Indication also includes everything from mounting hardware to LED Drivers and light pipes, as well as other useful replacement parts.

An infrared emitter or IR LED is a discrete component that emits light in the infrared spectrum. Typical emission wavelengths in this spectrum include 875nm, 880nm, 890nm, 940nm and 950nm. IR LEDs are used to transmit a signal or commands to a receiving device to accomplish specified tasks. They can also illuminate an area for safety, security or surveillance applications. Typical drive current for IR LEDs are in the 5mA to 50mA range.
IR LEDs are packaged in many form factors. Surface mount packages as small as 0402 are very popular with many options that can be optimized for optical or mechanical performance. Chip-on Board (CoB) options have the capability to accommodate multiple IR die in order to maximize performance in safety and security camera applications. There are many applications for side looker and through hole 3mm & 5mm LEDs.
An infrared detector or IR detector is a discrete component that that converts infrared light into an electronic signal. These devices are also known as photo detectors and sensors. IR detectors are sensitive in the 875nm, 880nm, 890nm, 940nm and 950nm wavelengths. IR detectors have typical supply voltage in the 5V to 20V ranges.
IR detectors are packaged in similar packages to their IR emitter counterparts. The two are generally “coupled” together for either communication or sensing applications. IR detectors can be packaged or coated with certain filters for ambient light immunity in high sunlight outdoor applications.
IR LED and detector applications are found in many unique applications where the benefits of this technology can be utilized such as:
Paper sensing Safety curtains Voltage Isolation Robotics
Fluid sensing Security cameras Wearable devices Industrial equipment
Currency validation Clinical diagnostics Internet of Things Phototherapy
IR illumination and sensing technology can be found in many market segments including commercial, consumer, industrial, medical, military and aerospace.
A LASER is a discrete semiconductor component that is able to project a highly concentrated light beam which is amplified due to stimulated radiation. LASERs can operate in the visible spectrum 400nm to 700nm, and in the invisible spectrum 850nm and higher. LASERs can be found in many applications from a simple LASER pointer to a CD /DVD prayer, bar code scanner, distance range finders, medical equipment, automotive crash sensors and others.
LASERs are categorized into power classes I to IV, the higher the number the more powerful and potentially hazardous the LASER beam. A LASER beam can focus on a very small spot on the retina and potentially result in a burn or blind spot. Eye safety is a critical part of any LASER system design.
LASERs are usually available in sealed metal can packages such as TO-56. This facilitates more accurate die mounting and heat management. Due to narrow bean angle emissions, there is no need for lensing so a flat glass window is common.
Key characteristics of Lasers are:
· Superior beam quality
· Close to perfect Gaussian beam
· Operating temperature -20C to 70C
· Lifetime of <10K Hours
· No additional lensing required
· Compact design
LASERs are common in many types of applications in the commercial, consumer, industrial, medical, automotive, military and aerospace applications.
An Optocoupler is a device that combines an IR LED emitter and IR detector used to convert the received infrared light into an electronic signal. They are packaged in a light-tight opaque plastic package with external leads for through hole or SMT assembly. The basic function of the Optocoupler is to switch a range of voltages on the output side while maintaining electrical isolation from the input side; thus preventing the high voltages from affecting the system receiving the switched signals. There are four common types of Optocoupler called: Phototransistors, Photodarlington, Photo-SCR and Photo-triac. Phototransistors and Photodarlingtons are used in DC circuits while Photo-SCR and Photo-triacs are AC circuits. Optocouplers are also known as Photocouplers and Optoisolators.
Common applications for Optocouplers are PC communications, microprocessor input/output signal switching, AC and DC control, power supply regulators and signal isolation. The signals being switched can be either analog or digital.
Optocouplers are common in many types of equipment applications in the commercial, consumer, industrial, medical, military and aerospace applications.

TTI offers displays in the following display technologies:
Fiber optics are flexible, transparent fibers that transmit light between its two ends. They are used in communications, where transmission over long distances and higher bandwidths are possible. The extruded glass or plastic fibers are immune to electromagnetic interference and have less loss than metal wires.
A High Power LED is an individual component that is greater than 0.20 watts, generally smaller in package size and finds applications where traditional lighting sources will not fit.

A LED is a semiconductor device that emits infrared or visible light when charged with an electric current. LEDs emit light wavelengths both visible and invisible when electrically charged. The color emitted is derived from the chemical composition of the semiconductor material used in manufacturing. LEDs are differentiated by their color/wavelength measured in units of nanometers (nm) or their color corrected temperature (CCT) measured in units of Kelvin (K). In addition, LEDs may consume lower power, provide longer lifetime, be more robust, and are able to be switched On/Off at very high rates of speed.
