1.LED In addition to the semiconductor lasers, when the current motivates the semiconductor diodes can emit the optical radiation. Strictly speaking, the term LED should be only applied to emit the visible Diode; The diode which can emit near-Infrared radiation is called infrared light emitting diode (IRED, Infrared Emitting Diode); The emission peak wavelength is limited near the shortwave, the d...
LPCE-2(including spectrophotometer, integrating sphere) is designed for analyzing the photometry, colorimetry and electricity of LED lamp, energy-saving lamp, fluorescent lamp, high-voltage sodium lamp, high-voltage mercury lamp, metal halide lamp and phosphor, completely meets the test requirements of CIE for photometry and colorimetry. Measure and display the relative spectral power distributio...
With LED technology development, LED applications in market are more and more wide. UV-C LED germicidal disinfection applications market also reaches a new height in 2016, prospects are bright. With more and more LED companies launch new products, UV-C LED technology will also develop faster. Wavelength of 200~280nm UV part is called UV-C region; this region UV wavelength is short and has high ene...
LED is not only a semiconductor device, but also a light source. It has the advantage such as high light output, low consumption and easily drove. LED is regarded as the most competitive light source in 21st century. LED’s quality should be tested by checking its photometry and electric parameters. Lisun designed and reseached a series LED Test instruments on chromatic, optic, color, electric...
