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.

LED Display/Dot Matrix  A dot matrix LED is a display device used to display information on machines, stock market, stadiums, bank, train and bus station display panels and many other devices requiring a simple display device of limited resolution.  The display consists of a dot matrix of lights or mechanical indicators arranged in a rectangular configuration such that by switching on or off selected lights, text or graphics can be displayed. A dot matrix controller converts instructions from a processor into signals which turns on or off lights in the matrix so that the required display is produced.  Dot matrix LED Displays are offered in a variety of array configuration packages such as 5*7, 5*8, 8*8, 16*16 and 32*16 options, and color choices include green, red, yellow, white, blue, orange, Bi-Color and RGB.
