What does ggy mean?
High pressure mercury lamp. The high-pressure mercury lamp is a high-pressure mercury vapor discharge lamp coated with phosphor on the inner surface of the glass shell, with soft white light and simple structure.
The inductance ballast is an iron core inductance coil. the property of the inductance is that when the current in the coil changes, it will cause the change of the magnetic flux in the coil, resulting in the induced electromotive force, which is opposite to the direction of the current, thus hindering the change of the current. Used in fluorescent lamps.
Doggy [dgi] the United States [d:gi] n. Puppy, puppy; adj. Like a dog; I want to have a doggy. I want to have a puppy.
What is the difference between industrial lighting and general lighting?
The main results are as follows: 1. The difference among commercial lighting, engineering lighting and consumer lighting is mainly in the application field of lighting. Commercial lighting mainly refers to the space environment lighting of shop lighting, hotel lighting, supermarket lighting and commercial real estate lighting, which are mainly used for commercial applications.
2. The specification of industrial lighting is relatively high. General lighting focuses on the lighting effect, while industrial lighting is not urgent only focus on the lighting effect, more aimed at its use scene, such as coal plant ordinary lighting is definitely not good, the need for professional mine flameproof lighting; the port also needs professional waterproof and dustproof lighting.
3. Being able to become an industrial lighting means that the quality should be better than that of ordinary lighting. In addition to high power and brightness, industrial lighting is better than ordinary lighting in terms of material and performance. More detailed comparison data can be viewed on the official website of Shangwei Lighting.
4. The difference between industrial electricity and lighting electricity: the voltage of lighting power is 220V, and the voltage of industrial electricity is 380V. There are only two phases of hot wire and zero line for lighting; industrial power includes three phases, which are connected by star connection or triangulation, and there is no zero line. Additional grounding is required.
Which company does better lighting without headlights?
Think of Tiansanfeng Aike Gu set Leishton frontal magnetic world three strong lighting foil crystal sunlight lighting. Enterprise 1: committed to the research and development of LED lighting in civil and commercial fields, pay attention to quality and health.
Headless lamp brand like the top ten brands of headless lighting in China, specializing in high-power LED lighting enterprises, set design, research and development. Top three headless lamp brands in China, specializing in high-end intelligent magnetic track lamp manufacturers, the industry’s first invention.
Headless lamp brand which good ownerless lamp brand one of China’s top ten headless lamp brands, famous headless lamp lighting brand, committed to LED lighting in civil and commercial fields. Headless lamp brand like the top ten brands of headless lighting in China, specializing in high-power LED lighting enterprises, set design, research and development.
The top ten brands are Qiyi, Ike, Top three, Rex, Guji, TCL Lighting, foil Crystal, Opal, Osram, Tiantian. The lamps and lanterns designed without headlights include downlights, spotlights, track lights, linear lights, magnetic track lights, among which downlights and spotlights are the most used.
What is the difference between Class I, Class II and Class III lamps and lanterns?
1. Different types of lamps and lanternsThe scope includes category II lamps and lanternsClass II lamps and lanterns include three types of lamps and lanterns. These threeThe relationship is that the grade of class I lamps and lanterns is greater than that of class II lamps and lanterns, and that of class II lamps and lanterns is larger than that of class III lamps and lanterns.
2. The scope they contain is also different. Class I lamps and lanterns include Class II lamps and lanterns, while Class II lamps and lanterns include Class III lamps and lanterns. The relationship between these three is that the level of class I lamps and lanterns is greater than that of class II lamps and lanterns, and that of class II lamps and lanterns is larger than that of class III lamps and lanterns. The measures taken by these three kinds of lamps to prevent electric shock are different.
3. The protection of second-class products not only depends on insulation, but also adds additional protection, such as measures to strengthen insulation. And the three types of lamps and lanterns, its voltage is safe ultra-low voltage, and will not produce high voltage state.
4. The anti-electric shock protection measures of these three kinds of lamps are different. (1) the protective measures against electric shock of first class lamps and lanterns are more comprehensive, which are mainly reflected in three measures: first, basic insulation.The second is additional safety measures and the third is the grounding of conductive parts.
