Three major trends in the future development of China's lighting industry
Lighting industry after more than thirty years of development, to this day, the public well-known brands are still ****. This is certainly related to the industry's low attention to industry attributes, but the more important reason is that the vast majority of lighting companies brand awareness is weak, they put their efforts on the product and price level of competition, rather than the brand and cultural level of competition. Of course, there are some enterprises, want to do the industry well-known brand, but not rules and regulations, half the effort.
LED lighting installation must be tested for points
1. luminous intensity detection Light intensity is the intensity of light, is the amount of light emitted within a certain angle. Due to the concentration of light-emitting diode light, the inverse square law is not applicable to short-range situations. cie127 standard for measuring the average normal light intensity provides two conditions: measurement condition A (far-field conditions) and measurement condition B (near-field conditions). The detector area in both cases is 1 cm2. usually, the standard condition b is used to measure the luminous intensity
8 common LED lamps and lanterns optical parameters testing techniques
The intensity of light, that is, the intensity of light, is the amount of light emitted at a certain angle. cie127 standard, the light-emitting diode due to the light is more concentrated, the inverse square law does not apply, cie127 on the measurement of light intensity proposed measurement conditions A (far-field conditions), measurement conditions B (near-field conditions) two conditions for measuring the average normal light intensity, 2 conditions are 1cm2. generally speaking, the The luminous intensity is measured using the standard condition B.
