GB19573-2004
Limited values of energy efficiency and rating criteria for high-pressure sodium vapour lamps
高压钠灯能效限定值及能效等级
GB 19573-2004 is a current mandatory Chinese national standard for Limited values of energy efficiency and rating criteria for high-pressure sodium vapour lamps. It appears in the Construction compliance cluster with a energy efficiency focus and has an implementation date of Feb 1, 2005.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies to high-pressure sodium vapour lamps used for indoor and outdoor lighting with transparent glass shells. It covers products with a power range of 50W to 1000W, designed to operate with corresponding ballasts and igniters within 92%~106% of rated voltage. It is not applicable to lamps outside this specified power range or those without transparent glass shells. The basic performance of these lamps must comply with GB/T 13259.
Technical requirements
The standard classifies the energy efficiency of the lamps into three grades, with Grade 1 representing the highest efficiency. It specifies the minimum average initial luminous efficacy requirements for each grade, as well as the minimum efficacy for individual samples. The mandatory energy efficiency limited value corresponds to Grade 3. Furthermore, the standard outlines requirements for lumen maintenance at 2000 hours of operation, with specific percentage thresholds varying by wattage. An energy conservation evaluating value is also established, which is based on the parameters of Grade 2.
Testing methods
Testing involves measuring the average initial luminous efficacy after aging the lamp for 100 hours, following the photometric testing methods specified in GB/T 13434. The efficacy is calculated as the ratio of initial luminous flux to measured power, and the arithmetic mean of the sample size is taken. Manufacturers must conduct delivery inspections for the mandatory limit values and routine inspections for lumen maintenance at least annually.
FAQs
What products are regulated under GB 19573-2004?
It regulates ordinary high-pressure sodium vapour lamps with transparent glass shells, ranging from 50W to 1000W, used for indoor and outdoor lighting.
What is the mandatory energy efficiency requirement in this standard?
The mandatory energy efficiency limited value is defined as Grade 3. Additionally, individual samples must have an initial luminous efficacy of no less than 90% of the Grade 3 average.
How is the initial luminous efficacy tested according to GB 19573-2004?
Lamps are aged for 100 hours, and the luminous flux is measured according to the methods in GB/T 13434. The initial luminous efficacy is then calculated by dividing the luminous flux by the measured power.
