1. Photoelectric test system

LPCE-2 high precision spectral radiometer & integrating sphere system mainly tests energy-saving lamps, fluorescent lamps, HID lamps (such as high-pressure sodium lamps and high-pressure mercury lamps), cold cathode fluorescent lamps and LED lamps. The test results meet the requirements of CIE and ies lm-79. The LPCE-2 system adopts LMS-9000B/ LMS-9500 high-precision rapid spectroradiometer and one-step molding technology to produce a new type of integrating sphere with carrier. The test accuracy of integrating sphere is much higher than that of traditional integrating sphere.

 

Measurement parameters:

Color parameters: chromaticity coordinates, related color temperature, color ratio, peak wavelength, half bandwidth, main peak wavelength, color purity, color rendering index, CQS, spectrogram, etc

Luminosity parameters: luminous flux, luminous efficiency, radiation power, pupil lumen, Si Chen visual lumen, par, PPF (only LMS-7000 and LMS-9000 can meet the test)

Electrical parameters: voltage, current, power, power factor

LM-80 LED luminous flux maintenance rate test: luminous flux vs time, color temperature vs time, color rendering index vs time, power vs time, power factor vs time, current vs time and luminous efficiency vs time

The lsrf-3 is equipped with a class a fast photometric probe, so the sampling speed is as high as 100 kHz. It fully meets the requirements of basic, energy star v2.1, IEC PST, CA, CEC, assist, CIE SVM, IEEE Std 1789.

2. Distributed photometer for lamps and signals of traffic vehicles

LSG-1950 is a distributed photometer recommended by CIE a - α. It is mainly used to measure traffic lights, such as traffic lights, buses, trains, ships, aerospace equipment lamps. When the test sample rotates around the horizontal and vertical axes, the probe remains stationary and faces the object to be tested, so as to test the light intensity and illumination value of the lamp under test. LSG-1950s is an economical version, which is suitable for small traffic lighting factories.

4. EMC test of automotive electronics

The equipment of motor vehicle will produce electrical and radio frequency disturbance in normal operation. The frequency band of these disturbances is very wide, and it is transmitted to the vehicle electronic equipment and system through conduction, coupling or radiation. In recent years, more and more electronic devices with various functions such as control, monitoring and display are used in automobile design. Therefore, the electrical and electromagnetic environment in which these devices work must be considered. Especially for the disturbance of vehicle electrical appliances. These disturbances may result in reduced function of electrical equipment (temporary failure or even permanent damage). The worst cases are often caused by disturbances from the vehicle itself, such as those from the ignition system, generator and rectifier system, motors and actuators.

Reference standard:

Immunity of vehicle radiated disturbance:

Iso11451 "electrical interference from narrowband radiated electromagnetic energy of road vehicles - vehicle test method"

Immunity to radiation disturbance of parts and components:

Iso11452 "electrical interference from narrowband radiated electromagnetic energy of road vehicles - Test Method for components", GB / t17619

Immunity to conducted disturbance of parts and components:

ISO7637 "road vehicles - Electrical disturbances caused by conduction and coupling", GB / t21437

Static immunity of vehicle and parts:

Iso10605 "electrical interference from electrostatic discharge of road vehicles", GB / t19951
