Introduction
is a kind of lighting product commonly used in civil lamps. Its purpose is to provide a lighting level that is significantly higher than that of the surrounding environment.
It is often used for reading (reading) , Writing, drawing and task lighting for computer operation area. Its characteristic is that the working position of the lamp is on the desktop or the ground. The lamp can be easily moved with the power supply according to the needs of use; but in the process of use, people can easily touch the outer surface of the lamp, the lamp is easy to be overturned by external force, and the power cord of the lamp is easily exposed to external force. Therefore, in addition to the general safety requirements, the portable luminaire should also have sufficient stability, and be equipped with a wire stress relief device, and the outer surface of the luminaire that is easily accessible by people should not be overheated.
Classification
The portable lamps are divided into two types: charging type and fluorescent type
purchase instructions
The desk lamp is the most common type of portable general-purpose lamps, and it is also an indispensable lighting product for students’ desks and teachers’ desks. The age span of the population is large, and it involves children's use, and product safety is particularly important. When purchasing, first consider the safety and quality of the lamp, and then consider the factors of performance and appearance.
Pay attention to the following six items: 1. Go to a regular store and buy regular goods. You need formal invoices, do not buy products that are too cheap, buy products with three guarantees, and buy lamps with 3C certification marks.
2. The advertisement is for reference only. It is very important to check the inspection report, especially whether the items of electric shock protection, durability test and burning resistance in the inspection report are qualified.
3. You should look at it three times when purchasing. Look at whether the product identification is complete. The identification of regular products is often more standardized. At least the following content should be identified: trademark and factory name, product model specification, rated voltage, rated frequency, and rated power. Check whether the product model matches the specifications of the inspection report and safety certification certificate, and whether the electrical parameters are correctly identified; second, whether the power cord of the lamp has the CCC safety certification mark, and the cross-sectional area of the external wire should be 0.75 square millimeters; third, look at the lamp Whether the charged body is exposed, after the light source is installed in the lamp holder, the fingers should not touch the charged metal lamp holder.
4. Choose a table lamp with a higher level of protection against electric shock. According to the type of protection against electric shock, the table lamp can be divided into class 0, class I, class II and class III. Most of the products sold on the market belong to Class 0 or Class II. Class 0 lamps rely on basic insulation as protection against electric shock. If the basic insulation fails, it is prone to electric shock hazards. The electric shock protection of Class III lamps not only relies on basic insulation, but also has additional safety measures, such as double insulation or reinforced insulation. In case of failure of basic insulation, it can also rely on supplementary insulation protection. You should try to buy type II lamps marked with a type II return symbol.
5. When choosing table lamps for children, try to avoid buying table lamps with high heat-generating metal shells, such as incandescent table lamps and tungsten halogen table lamps. At the same time, you should also pay attention to the stability of the lamp when buying, to avoid the lamp being placed incorrectly and causing it to tip over. The stability of the lamp can be judged by tilting the lamp 6 degrees to see if it is overturned.
