Portable luminaries for basic common sense
Portable lamps are commonly used in commercial lamps in a lighting products, designed to provide operating area was significantly higher than the level of ambient lighting, commonly used in reading (reading), writing, drawing and computer work area lighting. It features the work of the lamp position is the desktop or on the ground, according to the use of the power needed fixtures can be attached easily to move; but in the course of human easy-to-reach outer surface of the lamp, lamp vulnerable to external forces and dumping, lamp power cord vulnerable to external forces damage, so in addition to general safety requirement, Portable lamps should also have sufficient smoothness and have a wire stress relief devices, people tend to touch the outer surface of the lamp should not be overheated. 1, the main safety requirements and electromagnetic compatibility requirements
Light cross-sectional area of the internal wiring and external wiring of the cross-sectional area should not be less than 0.5 to 0.75 mm2.
Lighting should be durable to use. Fluorescent lamps should be used not only in the normal state to resume normal work, and in the event of lamp aging, damage to the case provides an exception to protect the ballast. Incandescent lamp shell, lamp shade, insulation, etc. In the endurance test lamp should not burnt, not deformed.
Adequate electrical creepage distance and clearance.
Lamps in the main safety components, insulation material should be heat-resistant, fire-resistant.
Lamps should have sufficient protective measures against electric shock.
Lamps should have a reasonable structure design and a complete processing technology.
Lamps should be fitted with soft-line fixation. Lamps should have sufficient smoothness.
Lighting electromagnetic disturbance shall be within the limits specified in the standard.
The lamp should be in the standard harmonic currents within the prescribed limits.
2, How to Choose Portable table lamp
Portable table lamps, lamps in general the most common form, is also a student desks, teacher's desk essential lighting products, due to the use of large span of age groups, but also to children, product safety is particularly important. When you purchase your lights should first consider the safety and quality, and then consider the performance and appearance factors.
1. Into a regular store and buy regular merchandise. To regular invoice, the price is too cheap not to buy products, choose the "three guarantees" promised, buy a 3C certification mark of the lamps.
2. Advertising purposes only, access to inspection reports is very important, particularly in the inspection reports should be consulted to protect against electric shock, durability testing, burn-resistant items such as eligibility.
3. Purchase should be three to see. To see whether a product identification and complete, formal identification of products tend to be more standardized, or at least identify the following: trademarks and the make, Model specifications, rated voltage, rated frequency, rated power. Model verification about whether the inspection reports and safety certificates consistent with the model specifications, electrical parameters are identified correctly; two lamp power line to see whether there is CCC safety certification mark, the external conductor cross-sectional area should) 0.75 mm2; 3 to see light charged body is exposed, light source into holder, the finger should not touch live metal lamp.
4. Choose a higher lamp protected category against electric shock, according to the protection against electric shock type, table lamps can be divided into Class 0, I Class, â…?and â…?type classes. Products sold on the market are mostly Class 0 or Class â…? 0 type lamps rely on basic insulation as a protection against electric shock protection, if the basic insulation failure, it is easy to produce an electric shock hazard. Class â…?lamps not only rely on basic insulation to protect against electric shock, but also has additional security measures, such as double insulation or reinforced insulation, in case of failure of basic insulation, but also rely on additional insulation protection. To choose a class â…?marked "return" symbol class â…?lamps.
5. Select table lamp for children, should try to avoid buying high-calorie light hair metal lamp, such as incandescent lamps and tungsten halogen lamp. Meanwhile, attention should also purchase a smooth lighting, so as to avoid placing lamps do not lead to the overturning of the time. Lamps can be tilted six degrees to see if overturned to determine the smoothness of the lamp.
Third, the use of lamps Information
Buy lamps, the first not to busy to install, look at the lamp should be carefully marked, and read the installation manual, in accordance with the instructions of the installation of lamps, according to instructions in the use of rules of the use of lamps.
Signs provided by the timely replacement of aging of light source parameters of the lamp, the lamp was found at both ends of red, fluorescent tubes and jump off when the lamp should be replaced in time to prevent burn out ballast, etc. insecurity.
In the cleaning and maintenance should be careful not to change the structure of lamps, and do not easily replace the lamp parts, in the cleaning and maintenance after the end of the lamps should be installed as is good, do not drain containers, the wrong parts installed lamps.,
Light cross-sectional area of the internal wiring and external wiring of the cross-sectional area should not be less than 0.5 to 0.75 mm2.
