1. The allowable tolerance range of standard light source calibration and retest results is as follows: X, Y Chromaticity Coordinates: ±0.0008 Color Temperature: ±10K Luminous Flux: ±5‰ SLS-50W_Standard Lamp 2. The allowable tolerance range of contrast light source/ luminaires retest results as follows: X, Y Chromaticity Coordinates: ±0.0050 High Color Temperature: ±150K Low Color Temperatu...
The most critical factor that affects the quality of lighting is the luminous distribution performance of lamps. Using scientific testing methods and selecting the appropriate test instrument is the basis of obtaining accurate luminous distribution properties of luminaires. The test of luminaires’ luminous distribution is an important part of luminaire design and lighting design for quality con...
Xenon lamp aging test chamber adopts xenon arc lamp which can imitate the full spectrum sunlight to reappear destructive spectral wave in different environment. It can provide the corresponding environment simulation and accelerated test for scientific research, product development and quality control. It is also named “Sunlight Radiation Protection Test Device”. According to test standards an...
Definition: Means luminaries or light sources emit light intensity distribution in space. It can record the luminous flux of luminaries, light quantity, power, power factor, the size of the luminaries, luminaries efficiency including manufacturer of luminaries, type and other information. But the most critical is to record the light intensity distribution of luminaries in all directions. The gon...
IEC 62262 (How to install the EUT when doing the IK degree protection test, ventilation requirements, quantity of hammer, distribution of the hammer and hammer each level corresponding), the IEC62262, IEC60598 (GB7000) and IEC 60068-2-75 (GB2423.55) standards applications IK degree test with lightings. The main purpose of these standards is regulate relevant test procedures and test way of doing t...
IEC 61000-4-5 is part of the IEC 61000 series, which describes surge immunity testing caused by over-voltages from switching and lightning transients. The second edition of IEC 61000-4-5 was released in 2005 and has been in use for many years. The third edition was released as an EN standard in 2014. The general philosophy of the third edition is unchanged from the second edition. However there ha...
LVD’s goal is to ensure the safety usage of low-voltage equipment. Its range of application is on electrical products with voltage at 50V to 1000V AC and 75V to 1500V DC, including all the safety rules of this equipment, and protection against hazards caused by mechanical. The design and construction of the apparatus shall ensure or as its intended usage that it is not dangerous when used under ...
Standards GB17743-2007 / CISPR 15:2005 <Limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment> instead of the standards GB 17743-1999 and GB 15734-1995. The limits for the 2m diameter loop antenna apply to equipment not exceeding a length of 1.6m, those for the 3m loop diameter for the equipment having a length in between 1.6m and...
Nowadays, with the development of LED industry, its technology continues to be mature and has widely applied at home and abroad. Comparing to mature markets in Europe and America, LED lighting industry also has been very popular in Southeast Asia Blue Ocean market. Currently, it has not been strictly required for indoor LED lighting product specifications and certification in the Southeast Asian m...
