The Beijing Municipal Administration of Industry and Commerce recently commissioned the Beijing Lighting Electrical Product Quality Supervision and Inspection Station to monitor the quality of lamps sold in the Beijing market. The monitoring results show that there are six quality problems in some lamps.
First, the marked items are not qualified. The mark tells the user some important information about product performance, installation, warnings, etc., as well as the test conditions and methods. The main problem is that there is no zero-fire line mark on the terminal block or the wire, and the correct installation of the power line cannot be guaranteed, and the position of the mark is not correct or not secure.
Second, the structural project is unqualified. The structure is the most basic item in the safety inspection of lamps. The structure of the luminaire is mainly composed of components, connecting parts, insulating parts, assembly parts, etc. The standards set clear requirements for installation methods, insulation, fire prevention, drainage, anti-corrosion, anti-vibration, and protective measures. The problem is mainly manifested in the absence of protective measures around the terminal block, which is easy to electrify the lamp housing. In addition, the spring clip of the clip-type table lamp, the clamping strength is not enough, it is easy to slip, causing the glass of the light source to be broken and hurting. If the lamp is detached during operation, the power supply may be short-circuited and an electric shock may occur.
Third, the grounding provisions are unqualified. The standard requires that Class I lamps not only have a grounding mark, but also that the grounding device and other detachable metal parts should have good contact, but some of the lamps are not well grounded. When the lamp housing is charged due to leakage, it will hurt people's lives.
4. The external and internal wiring items are unqualified. The main problem is that the inner and outer wires are too thin, and the wires are easy to aging under high current working conditions. In severe cases, the lamps are short-circuited and endanger the safety of life and property. The standard requires that the lamp can not touch the charged body in any part of the human body during installation and use. Some fluorescent lamp holders, Luokou lamp holders, and nominal Class II lamps do not use double insulation or reinforced insulation, which can easily cause electric shock. .
5. The thermal test project is unqualified. Standards require that any part of the luminaire shall not become unsafe after the illuminating test of the luminaire under abnormal working conditions. For example, the lamp shall be cracked, burnt and deformed. The mark shall be clearly visible after the test. It is required for the luminaire with ballast to work normally. The main problem is that some lamps use magnetic ballasts, the measured temperature of the windings is larger than the allowable range, and some lamps use electronic ballasts. After abnormal tests, the lamps cannot work normally. Some mirror headlights and walllights that use fluorescent lamps are more problematic.
6. The insertion loss, disturbance voltage, and harmonic current limit items are unqualified. The failure of these three indicators can directly affect the safety of the power grid. When the indicators exceed the standard, the safety of adjacent power equipment will be affected, especially the normal operation of digital equipment such as computers, telephones and video equipment.
