Modern lamps include home lighting, commercial lighting, industrial lighting, road lighting, landscape lighting, special lighting, etc. What problems should be paid attention to when purchasing lamps?
1. The lamp identification must be clear
When purchasing lamps and lanterns, first look at the lamps and lanterns logo, such as trademark, model, rated voltage, rated power, etc. Marking safety is the basic requirement of lamp safety performance, of which rated power is particularly important. If the selected lamp power exceeds the standard, it may cause problems such as shell deformation and insulation layer damage.
2. Pay attention to material filaments
The bulb sockets of general incandescent lamps are all made of white iron, which is easy to rust. Lamps with better quality are usually made of aluminum alloy, which is not easy to rust. The better lamps are all double tungsten wires, while the worse lamps are usually single tungsten wires.
3. The cross-sectional area of the conductor is marked
To reduce costs, individual manufacturers may use wires with a cross-sectional area smaller than this standard, which may scorch the wires and burn out the insulation layer, resulting in short circuit and danger. When purchasing, you can look at the marks printed on the insulation layer outside the wires of the lamp.
4. Protection function of electric ballast
Electric ballast in lamps and lanterns should have abnormal protection function. Abnormal protection refers to the protection given when an abnormal state occurs to the fluorescent circuit, so that electric ballast can still work normally. For this abnormal state, electric ballast should add protection circuits to prevent damage to electronic components.
Finally, pay attention to the price.
When buying lamps and lanterns, don't just try to be cheap, because the quality and price are definitely in direct proportion.
