Scope

Main Technical Content: **7.1 Basic Requirements** The LED road lighting products covered by this standard either include luminaires with secondary light distribution or LED modules that do not require re-distribution after installation in road lighting luminaires. **7.2 Measurement and Calculation of Carbon Footprint (GHG Emissions) for LED Road Lighting Products** The rated luminous flux of LED road lighting products shall be tested in accordance with the provisions of GB/T9468-2008, Section 5.3, "Luminaire Luminous Flux Testing". The actual power consumption of LED road lighting products under nominal operating conditions shall be measured by testing their luminous flux for 10 hours of continuous operation and then measuring it again after 14 hours of inactivity. The average of these two measurements shall be used to calculate the actual power of the LED road lighting products. The carbon footprint (GHG emissions) of LED road lighting products shall be calculated using the following formula: ``` C = P × T × K ``` where: - C: Carbon footprint, in kilograms of carbon dioxide (kgCO2). - P: Actual power of the LED road lighting products, in watts (W). - T: Service life of the LED road lighting products, in hours (h). For this standard, T = 30,000 h. - K: Power-related CO2 emission factor, in kgCO2/kWh. For this standard, K = 0.6101 kgCO2/kWh (reference: T/DZJN 001—2018, Appendix C). **7.3 Carbon Label Grading** 7.3.1 Carbon Label Classification for LED Road Lighting Products LED road lighting products are divided into three carbon label grades based on their carbon footprint: **One Star**, **Two Star**, and **Three Star**, where the Three Star grade has the lowest carbon footprint (GHG emissions), followed by Two Star, and finally One Star. 7.3.2 Specifications for LED Road Lighting Products LED road lighting products are classified according to their rated luminous flux into five specifications as shown in Table 1.
