China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

a), lamps and lighting fixtures of electric shock protection does not meet the standard requirements. Protection against electric shock is an important index in evaluation of safety properties of lamps and lanterns, national standard, lamps and lanterns in the normal installation, wiring, replace the lamp, replace the starter, can not touch the live parts. Such as: standard fluorescent lamp components the lamp plug or unplug the lamp holder, lamp holder should be able to provide protection against electric shock. There are 21 kinds of products in this sample against electric shock protection is not qualified. The main reason is the lamp holder can't provide enough protection against electric shock, when the lamp pins are inserted into or pulled out of the lamp holder, charged pins of electric shock danger, lamp base not to protection against electric shock

b), the durability of the lamp is not qualified. Lamp durability test is rated lighting fixtures in normal work within the expected time of major security projects and standard requirement is: after the test, lamps shall not be unsafe; any part of the lamp shall not fail; luminaire marker should be clearly visible. The spot checks of 16 kinds of product durability of the project is not qualified. Main reason is used inside the fluorescent lamp inductance ballast and electronic ballast without abnormal state protection measures, under abnormal conditions, ballast immediately damage or burn the lamp does not continue to use the

c), harassment voltage exceeding the prescribed standards. National standard requirements in the frequency range from 9kHz to 30MHz, the frequency of the disturbance generated by the lamp should be less than 110dB V ~ 56dB ~ V, the average value of the disturbance voltage should be less than 46dB V ~ 56dB V. There are 10 kinds of products in the electronic ballast of the disturbance voltage exceeds the standard limit value. The use of disturbance voltage exceeds the limit value of lamps and lanterns, will directly affect the surrounding broadcast television receiving effect and instrumentation of the normal work for the sampling results, around the quality and technology supervision departments to strictly in accordance with the provisions of the product quality law and other relevant laws and regulations, on the spot checks of the quality of the products failed enterprises investigated and dealt with according to law. And urge enterprises to rectification; on the spot checks of products with better quality products and their production enterprises, to intensify propaganda. At the same time, urge enterprises to seriously study the relevant national standards, and promote the overall quality level of fixed lamps and lanterns products industry to improve how to buy a fixed style ceiling lamps

Fixed ceiling ceiling lamp is family, office, entertainment and other places often choose lamps and lanterns, at the time of purchase should first consider the safety and quality of lamps and lanterns, and according to the room size, height and functions of aspects to consider when choosing 1, in a big store, buy a "three packs of" commitment to the products of choose and buy, CCC certification mark lamp 2, when you want to buy three. A look at the product identification is complete, regular product identification is often more standardized, should be identified: trademark and factory name, product type specifications, rated voltage, rated frequency, rated power. Two see the lamp power line is the CCC safety certification mark, the external conductor cross-sectional area should be greater than or equal to 0.75mm2. Third, look at the lamps and lanterns charged body is exposed, the light source into the lamp holder, the fingers should not touch live metal cap 3, higher anti electric shock protection categories.

According to the protection of electric shock, the top of the ceiling lamp can be divided into 0 categories, I, II and III. The poor safety of 0 kinds of lamps, should try to choose the I class, class II and III 0 lamp lamps are to rely on basic insulation as a protection against electric shock, in the event of failure of basic insulation, protection against electric shock prone to the risk of electric shock type I lamp not only rely on basic insulation, but also includes additional security measures, that is easy to touch the conductive parts connected to the grounding protection wire, so that the conductive parts accessible grounding symbol grounding terminal in the basic insulation failure is not caused by charged I lamp side, it should be noted that, the metal shell I lamp should be effectively grounded, if can be reached for the lamp ballast, ballast effective grounding type lamp protection against electric shock not only to rely on basic insulation, and has additional safety measures, such as double or reinforced insulation, in case of failure of basic insulation, but also rely on the protection of insulation. Plastic casing of the lamp is generally 0 class or class II, the best buy class II luminaire, class II lamp with symbol class III of lamp protection against electric shock relies on power safety extra low voltage and inside the lamp does not produce voltage higher than the safety extra low voltage

d), the use of lamps and lanterns:
After you bought the Lamps, you should carefully read the marker lamps and read the installation instructions, in accordance with the instructions to install the lamp, according to the instructions in the use of rules use the lamps and lanterns according to mark the source parameters timely replacement of aging of the lamp, redness of the both ends of the lamp should be timely replacement of lamp, structure for preventing ballast burn insecurity in cleaning and maintenance should pay attention to, do not change the lamp, do not just replacing the lamp parts, in cleaning and maintenance after the end of, should according to the sample luminaire shall be installed, do not drain installation, mistaken installation lighting components.
