In recent years, the sampling pass rate of lighting products has been hovering between 40% and 60%. How to make the lighting products shine? On the afternoon of March 18, the Shanghai Quality and Technical Supervision Bureau held a quality analysis meeting for lighting products for the production of lamps. Business is the pulse.
Last year, the Shanghai Municipal Bureau of Quality and Technical Supervision conducted a product quality supervision and inspection on the three types of lamps (movable lamps, fixed lamps and recessed lamps) produced and sold in the city. A total of 90 batches of various lamps were sampled. Only 58.9%, involving 57 batches of products produced in the city, the sampling pass rate was 71.9%.

From the results of the spot checks, the quality problems are mainly concentrated in the following aspects:
â– The insulating materials used in the lamps are not heat-resistant and fire-resistant, the durability test of the lamps is unqualified, the anti-electric shock protection of key components does not meet the requirements, or the protection against electric shock is invalid due to other design defects.
â– The electromagnetic compatibility index of the product does not meet the standard requirements, which causes the luminaire to affect the normal operation of surrounding broadcasting, TV reception and instrumentation equipment during use.
â– The identification of the product is incorrect, not standardized, and the correct power connection or necessary warnings are missing.
Cause
â– At present, some manufacturing companies still do not understand the product standards, or there is a deviation in the understanding of the standard requirements in the standards, resulting in defects in the design of the lighting products.
â– During the inspection of the incoming goods of the manufacturer, the insulation materials or key components in the lamps are not confirmed or verified, resulting in the loss of control of the key components, resulting in safety hazards.
â– Some enterprises attach importance to physical quality and neglect the quality of the logo, resulting in unqualified labels.
