Four standards such as 'evaluation method for color rendering of white light source' were submitted for approval and publicity

According to the '29 light industry, electronic industry standards and 3 Electronic Industry national standards for approval and publicity' issued by the science and technology department of the Ministry of Industry and Information Technology in July 24, 2017, 4 light industry standards are related to lighting products, the relevant information of the standards is as follows: according to the '29 light industry, electronic industry standards and 3 Electronic Industry national standards approval publicity' issued by the science and technology department of the Ministry of Industry and Information Technology in July 24, 2017, among them, there are 4 light industry standards related to lighting products. The relevant information of the standards is as follows :(1)QB/T 2516- 2017 'dysprosium lamp', the main contents of the standard: this standard specifies the classification and naming, main dimensions, basic parameters, requirements, test methods, inspection rules, signs, packaging, transportation and storage of dysprosium lamps. This standard is applicable to dysprosium lamps with power of 500 W and below and transparent glass bulb. The lamp is powered by an AC power grid with A frequency of 50 Hz of 220 V or 380 V according to different specifications, and the reference ballast and trigger conforming to the requirements of Appendix A are used at 92 ~ of the rated power supply voltage ~ Within the range of 106, it can start and ignite normally. (2)QB/T 5207-2017 adding Krypton to lighting products-85, thorium- 232 limit requirements, main contents of the standard: this standard stipulates that Krypton-is added to lighting products-85, thorium-A large allowable content of 232. This standard applies to the following lighting products: metal halide lamp or arc tube; Short arc mercury lamp; Short arc xenon lamp; Road motor vehicle bulbs. (3)QB/T 5208- 2017 evaluation method of color rendering of white light source, main contents of the standard: this standard specifies the calculation method of two measurement parameters for evaluating color rendering of white light source, includes color fidelity index Rf and color gamut index Rg. This standard is applicable to indoor and outdoor lighting levels based on bright vision, white light sources and lighting systems based on ordinary lighting. (4)QB/T 5209- 2017 'integrated LED lights for decorative lighting, performance requirements', the main contents of the standard: this standard specifies the product classification and naming, requirements, test methods, inspection rules, marking and packaging requirements of integrated LED lamps for decorative lighting. This standard is applicable to non-directional integrated LED lamps that are used as decorative lighting in homes and similar places and integrate LED light sources and stable ignition point components. The scope of application is as follows: Rated voltage AC220 V, frequency 50Hz; It conforms to GB/T 1406. 1 screw type lamp holder or in line with GB/T 1406. 5 bayonet lamp holder; The external dimensions meet the requirements of GB/T 7249, and the external diameter of the lamp is not more. All lamps that meet the requirements of this standard are at 92 ~ of the rated power supply voltage ~ 106 or within the nominal operating voltage range, the ambient temperature is- 20 ° C ~ It should be able to start and work normally under the condition of 45℃.
