According to the relevant personages of the Shanghai Municipal Administration of Industry and Commerce, from the data of this monitoring, the interchangeability of safety (the size of the metal lamp head) and the lamp power, initial light effect/light flux for preventing electric shock, reflecting product performance and service life The qualification rate of the color tolerance and harmonic current limit is low. During the monitoring, there are 1 batches of goods that are not qualified for interchangeability and prevention of electric shock. The main performance is that the size of the lamp head does not meet the standard requirements, and it cannot be screwed into the standard gauge lamp holder or the soldering height of the lamp head electrical contact does not meet the standard. Claim. Users who use such products are prone to electric shock and cause electric shock. If excessive force is applied, the lamp holder will be deformed and damaged, which may also cause unsafe conditions such as electric shock or short-circuit of power supply.
There are 7 batches of unqualified products for harmonic current limit items. If a large number of lighting equipment with unqualified harmonic current limit items are used within a certain range, the reactive power of the local power grid will increase, which will affect the power quality of the power grid. In addition, the increase of the reactive current will also cause the power supply transformer and the power transmission line to generate heat and consume electrical energy.
Energy efficiency limits, lumen maintenance, lamp power, and initial efficacy/luminous flux are important performance indicators that directly reflect product energy savings and product performance. During the monitoring, there were 9 batches with unqualified lamp power indicators, 8 batches with unqualified lumen maintenance rate indicators, 4 batches with unqualified energy efficiency limit values, and 4 failed initial light/luminosity indicators. batch. Products with unqualified indicators will cause early blackening during the use of energy-saving lamps, reduced illumination, shortened service life, and some can not be used in a few hundred hours, usually showing energy saving, power saving, and power saving. The phenomenon of money.
In this quality monitoring, there were many unqualified items in 5 batches of goods, and the quality problems were serious. For the unqualified commodities found in this monitoring, the industrial and commercial authorities will impose administrative penalties on the distribution enterprises according to law.
Purchase reminder to carefully purchase energy-saving lamps below 5 yuan
Shanghai Industrial and Commercial Organization reminds consumers to pay attention to the following matters when purchasing energy-saving lamps:
■To purchase products that have a “three guarantees†commitment. According to national standards, the luminous flux maintenance rate (corresponding to the amount of illuminance maintenance) of energy-saving lamps cannot be lower than 78% after lighting for 2000 hours. That is to say, if the household uses it, the energy-saving lamp should be able to be used for more than one year.
â– To "three look". That is: look at the announcement of the results of the spot checks published by the relevant departments, select the qualified brands from them; secondly, look at the product inspection report provided by the distribution company, especially the 2000-hour lumen maintenance rate in the inspection report; see if the product identification is complete. Regular goods generally have registered trademarks, factory names, factory addresses, and telephone numbers.
â– Carefully purchase goods that are too low in price. According to the production cost and sales status of energy-saving lamps, the retail price of 2u (4 tubes) energy-saving lamps below 9w is generally around 8 yuan, and the retail price of 3u (6 tubes) energy-saving lamps from 13w to 28w should be around 15 yuan. . The quality of goods that are priced below $5 is generally difficult to guarantee.

FR-4 or FR4 Epoxy Resin Plate is most commonly used as an electrical insulator possessing considerable mechanical strength. The material is known to retain its high mechanical values and electrical insulating qualities in both dry and humid conditions. These attributes, along with good fabrication characteristics, lend utility to this grade for a wide variety of electrical and mechanical applications.
NEMA is the regulating authority for FR4 Epoxy Resin Plate and other insulating laminate grades. Grade designations for glass epoxy laminates are: G10, G11, FR4, FR5 and FR6. Of these, FR4 is the grade most widely in use today. G-10, the predecessor to FR-4, lacks FR4's self-extinguishing flammability characteristics. Hence, FR4 has since replaced G10 in most applications.
We're the professional FR4 laminated sheet/plate manufacturer & supplier. We'll provide you the best quality FR-4 Epoxy Resin Plate(Fr4 Board) with competitive price.
