The principle of selection of lamps and lanterns
Lamps refer to appliances that can transmit light, distribute and change the light distribution of the light source. I believe many people do not know much about this definition, but they know that lamps are used for decorative lighting, but there are many types of lamps, and there is still a need for a certain selection. Pay attention to, then what is the principle of lamp selection? In addition to this, lamps are also distinguished by their pros and cons. What are the methods for identifying the quality of lamps? Next, BENWEI will explain it for everyone, let's take a look.
Principles of lamp selection:
In lighting design, you should choose lamps that not only meet the requirements of use function and lighting quality, but are also easy to install and maintain, and have low long-term operating costs. Specifically, the following aspects should be considered:
(1) Optical characteristics, such as light distribution and glare control;
(2) Economics, such as lamp efficiency, initial investment and long-term operating costs, etc.;
(3) Special environmental conditions, such as fire hazard, explosion hazard environment, dust, humidity, vibration and chemical corrosion environment;
(4) The appearance of the luminaire should be coordinated with the building;
(5) High lamp efficiency (η): η=ΦL/ΦO, depending on the shape and material of the reflector, the size of the light outlet, the shape and material of the diffuser or grid;
(6) IP rating that meets environmental conditions.
No matter what type of lamp you choose, you still need to consider some related factors to see if it is suitable. Secondly, the editor of Jiuzheng Lamps Network thinks that although the type needs to be selected, the quality cannot be ignored. Let's take a look.

How to identify the quality of lamps:
There are also fake lighting products on the market. Inferior lighting products are not only harmful to human eyes and eyesight during use, but also there are major risk factors in the use of inferior lighting products. If the quality is insufficient It’s very dangerous to close, explode and so on. As a consumer, from what aspects should we consider the quality of lighting products?
1. Material aspect
The bulb mouth of the general incandescent lamp is made of white iron, which is easy to rust. The better quality lamps are usually made of aluminum alloy, which is not easy to rust.
2. Filament aspect
The better lamps are all double tungsten filaments, and the poorer lamps generally use single tungsten filaments.
3. Brightness
For the lamp, if the good lamp is powder coated by the machine at one time, the brightness will be uniform after power-on, while the poor one will be powder coated manually and the brightness will be uneven.
4. In terms of price
Don't just choose a cheap one when buying lamps, because quality and price are definitely proportional.
5. Certification
It depends on whether it has 3C certification qualifications and audits its content.
6. New and old aspects
Innovative products may not have mature technology. When buying, don’t just choose the latest ones and ignore the old ones.
