In the second quarter of this year, the Gansu Quality and Technical Supervision Bureau entrusted the relevant quality inspection agencies at the provincial level to supervise and inspect the quality of 12 types of products such as bulb lamps produced (sold) in the province.
This time, a total of 60 batches of bulb lamps distributed by 52 enterprises in circulation area of ​​Lanzhou City were sampled, and 50 batches of products distributed by 43 enterprises were qualified. The qualification rate of enterprises was 82.7%, and the inspection rate of products was 83.3%. Market circulation field samples.
In accordance with the "Regulations on the Regular Supervision and Inspection of Self-Calculation Fluorescent Lamps in the Second Quarter of 2013" and related product standards, mainly for signs, prevention of electric shock, input power, mechanical strength, heat resistance, fire and flame resistance, initial light efficiency 8 major indicators such as (light flux) and power factor were tested; in accordance with the "Regulations on the regular supervision and inspection of lighting products quality in 2013" and related product standards, mainly for structural, mechanical strength, external wiring and internal wiring, and protection against electric shock 10 indicators such as moisture resistance (water resistance), insulation resistance and electrical strength, leakage current, creepage distance and clearance, and screwless terminals were tested. There were 10 batches of products with quality problems. First, external wiring and internal wiring do not meet the standard requirements.
The standard requires that the cross-sectional area of ​​the power cord connecting the leads is ≥0.4cm2, and the measured values ​​of the unqualified products are 0.3mm2 and 0.2mm2, respectively. The cross-sectional area of ​​the power cable is too low, which may cause dangers such as heating and fire of the power cord in the working of the lamp. Second, the initial luminous efficacy (light flux) of some products does not meet the standard requirements.
The standard requires an initial luminous efficacy (light flux) of ≥ 54 lm / w, and the measured value of the unqualified product is a minimum of 1 # 33 lm / w, 2 # 34 lm / w. Failure to pass will affect the lighting quality of the luminaire, misleading consumers, especially children's long-term use will affect vision; third, the input power and power factor indicators of individual products do not meet the standard requirements.
The standard requires "the difference between the actual power consumption and the rated power is ≤ ± 15%", and the measured value of the unqualified product is 27% and 33%. Excessive input power reduces the service life and also affects circuit safety. The power factor of the unqualified product is nominally ≥0.56-0.05 (0.51), while the measured value is 0.48, which does not reach the value indicated. If the power factor fails to meet the standard requirements, it will pollute the power grid and affect the quality of power supply. Fourth, the structural indicators of individual products do not meet the standard requirements.
The standard stipulates that the connection lead of the luminaire requires that if the lamp has a connecting lead, the connecting lead needs to be connected to the fixed wiring or the terminal without a separate terminal block. The unqualified product has no independent terminal after inspection. Terminals will not use lamps in use in connecting the internal wires and external wiring of the risk of loosening disengaged, resulting in leakage, electric shock and other accidents; Fifth, there are signs of some products are not standardized.
Although the rules of the spot check did not include the mark in the criteria for determining whether it is qualified, the problems found in the spot check are still prominent. The main manifestations are that the mark, the name of the manufacturer or the name of the seller, the rated voltage (V), Rated frequency or rated frequency range (Hz), rated input power or maximum rated input power (W) and quantity, structural symbol of the appliance, product model or model serial number, etc.
