Infrared LED/Phototransistor Phototransistors are either tri-terminal (emitter, base and collector) or bi-terminal (emitter and collector) semiconductor devices which have a light-sensitive base region. Phototransistors and photodiodes can both be used for sensing light, but the phototransistor is more sensitive in view of the gain provided by the transistor. This makes phototransistors more suitable in a number of applications. Phototransistors provide lower capacitance, high-speed response and low noise and low dark current along with excellent sensitivity. They are ideal for high-speed data transfer, light barriers, alarm systems, linear light measurement and more. Luckylight offers an extensive range of high quality and reliable phototransistors. They are available in a variety of shapes and sizes, including industry standard T1 and T1 3/4, and lens side look, as well as surface mount (SMD) type. Most widely used Silicon Phototransistors are sensitive from 400 to 1100nm.

Infrared LED/Photodiode A photodiode is a semiconductor device that converts light into an electrical current. The current is generated when photons are absorbed in the photodiode. The photodiodes are similar to regular semiconductor diodes except that they may be either exposed or packaged with a window or optical fiber connection to allow light to reach the sensitive part of the device. Many diodes designed for use specifically as a photodiode use a PIN junction rather than a p–n junction, to increase the speed of response. Photodiodes are used in a variety of applications including CD/DVD drives, Optical communications, Smoke detectors, Medical equipment, burglar alarms and general light sensing.

Infrared LED/IR Emitter 
 
An infrared emitter, or IR emitter, is a source of light energy in the infrared spectrum. It is a light emitting diode (LED) that is used in order to transmit infrared signals from a remote control. In general, the more they are in quantity and the better the emitters are, the stronger and wider the resulting signal is. A remote with strong emitters can often be used without directly pointing at the desired device. Infrared emitters are also partly responsible for limits on the range of frequencies that can be controlled. An IR emitter generates infrared light that transmits information and commands from one device to another. Typically one device receives the signal then passes the infrared (IR) signal through the emitter to another device. 
 
Luckylight offers many of the most common types categorized by wavelength, angle of half intensity, intensity, packaging type and forward (drive) current. The most common sizes for wavelength are 875nm, 850nm, 940nm. 
 
A. Infrared LED with wavelength of 940nm: suitable to be used in remote controller, such as remote controllers for household appliances. 
 
B. 850nm: suitable to be used in video cameras that are applied in digital photography, monitoring system, door phone, theft-proof alarm and so on. 
 
C. 870nm: suitable to be used in IrDA compatible data transmission, IR illumination for CCTV, miniature light barriers, Photo interrupter, optical switches, shaft encoders and more.

SMD LED/Reverse Mount Chip LED Luckylight offers an extensive range of high quality reverse mount chip LEDs which are small in size, high efficiency and low power consumption. Reverse mountable chip LEDs are for lighting the non-component side of a PCB board. In this reverse mounting configuration, this LED emits light through a small cut-out hole in the PC board. Reverse mount chip LEDs packages are available in popular SMD 1206 and wing lead type with different feature options in size, shape, viewing angle and color combination. Colors are available in blue, green, yellow, orange and red etc. These devices are packaged in automation-friendly tape and reel to increase productivity and reduce assembly cost. The small size, narrow footprint, and low profile make this kind of LED excellent for backlighting, status indication, and front panel illumination application.
