Infrared emission tube, also known as infrared emission diodes, are diodes.
It is possible to convert electricity directly into near infrared
Light (not visible light) and can radiate out of the light-emitting devices,
mainly used in a variety of photoelectric switches and remote control transmitter circuit.
Infrared tube structure, the principle and ordinary light-emitting diodes similar to the semiconductor materials used only different. Infrared light-emitting diodes are usually using gallium arsenide (GaAs),
arsenic gallium arsenide (GaAlAs) and other materials, using a transparent or light blue, black resin package.
Emission distance, emission angle (15 degrees, 30 degrees, 45 degrees, 60 degrees, 90 degrees, 120 degrees, 180 degrees),
the light intensity, wavelength. Above for the physical parameters, to understand the electrical properties of the parameters:
the market commonly used diameter 3mm, 5mm for the small power infrared emission tube, 8mm,
10mm for the power and high power launch tube.
Low-power launch tube forward voltage: 1.1-1.5V, current 20ma,
the power for the forward voltage: 1.4-1.65V50-100ma,
high-power tube for the forward voltage: 1.5-1.9V200-350ma.
Yu Star Electronics do Out of 1-10W high-power infrared emission tube can be applied to infrared surveillance lighting.
