Standard LM-79 and LM-80 comparison

IES LM-79-08 Approved Method: Electrical and Photometric Measurements of Solid-State Lighting Products. IES LM-79 standard is mainly for photoelectric performance measurement. Generally it is for whole lamp. Main measurement parameters as follow: Electrical Measurement: Voltage, Current, Power and Power Factor. Colorimetric Measurement: CCT, CRI and Chromaticity Coordinates Photometric Measurement: Luminous Flux and Luminous Efficiency Integrating Sphere System can measure upper parameters, but integrating sphere system cannot measure luminous intensity distribution. Luminous intensity distribution is measured by Goniophotometer. IES LM-79 emphatically compares the total luminous [...]

The Definition and Test Requirements of RF LED Lights

Definition of RF LED lights: RF LED light is emitting diode by converting the RF energy into light energy. LED lights are not always RF LED lights, for example, if the maximum working frequency of LED light is less than 9kHz, such as light with non-light source or directly supplied by DC power source (no drive power module), then it is not regarded as RF LED light. RF LED lights certification and testing requirements: Federal Communications Commission (FCC) has issued a KDB [...]

UV-C LED Prospect

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 energy. UV-C wavelength light has a great destructive effect on the body’s bacteria, viruses and micro-organisms. Sterilization [...]
