There are so many lamps in the industrial lighting market, how to judge the quality of a lamp, especially in the industrial lighting field, the lighting time is long and the use environment of industrial lighting lamps is complex, so we should pay more attention to the quality of products. Industrial lighting lamps are widely used, involving indoor, outdoor, underground, roads and so on. , so the variety is also very rich. Factors to be considered when purchasing industrial lighting lamps.

Chip brand

What brand is used for industrial lighting chips? Imported first-line brands have high light efficiency, long service life, small light attenuation and stability.

force

Poor quality power supplies are basically insufficient power, that is, if you take a 100w lamp, it is actually 40-50w, which will affect the life of the lamp.

Lamp shell material

Looking at the material of the lamp shell, the price of the lamp also depends on the use and purity of aluminum. If you choose high-purity all-aluminum and large heat sinks, you will naturally use more aluminum. Only when the materials used are real can the heat dissipation effect of the lamp be guaranteed.

Marking safety

When buying lamps, you should first look at the signs on the lamps, such as trademark, model, rated voltage, rated power, etc. To determine whether they meet your own use requirements. Marking safety is a basic requirement in the safety performance of lamps, among which rated power is particularly important.

electric shock protection

Pay attention to electric shock protection. Electric shock of lamps and lanterns is generally caused by using unqualified lamp holders or not covering the live parts of lamps and lanterns.

Conductor cross-sectional area

Pay attention to the cross-sectional area of the wire used in the lamp: when buying, you can look at the logo printed on the outer insulation layer of the wire on the lamp, and stipulate that the minimum cross-sectional area of the wire used in the lamp is 0.5 square millimeter. In order to reduce the cost, some manufacturers only use 0.2 square millimeter wire on their products. Under abnormal conditions, the wires will be burnt out, and the insulation layer will be short-circuited after being burnt out, which will cause danger.

Conductor safety

There should be no sharp edges at the entrance and exit of the metal pipe through which the wire passes. The metal parts can be chamfered or sheathed to avoid cutting the wire and electrifying the metal parts, resulting in electric shock.

Invoice contract

Invoices and contracts must indicate the specifications, quantity, price and amount of lamps.

Merchant information

Know the names, addresses, contacts and telephone numbers of markets and businesses, so as to solve quality problems in time.
