Both high-pressure sodium lamps and metal halide lamps are negative resistance elements. Inductive ballasts are positive resistance elements. As long as the impedance of the ballast matches the bulb, the normal operating range of the bulb current can be guaranteed. Take a 1000W metal halide lamp as an example.… Read More
Road lighting is an important part of urban lighting. Traditional street lamps are often used. High-pressure sodium lamps emit 360 degrees. The disadvantage of large light loss has caused a huge waste of energy. At present, the global environment is deteriorating, and all countries are developing clean energy. With the rapid growth of the national economy, the contradiction between energy supply and demand in China has become increasingly prominent, and there has been a serious shortage of power supply.… Read More
Stage lighting is an important part of the performance space. It is based on the development of the plot to perform a full range of visual environment lighting design for the characters and the specific scenes needed, and purposefully reproduce the design intent to the audience in an artistic way. The stage lighting allows the audience to have a better view There is no doubt that the stage lighting has a huge effect on the performance.… Read More
Illumination intensity is a physical term that refers to the luminous flux of visible light received per unit area. Abbreviated as illuminance [1], unit Lux (Lux or lx). It is used to indicate the intensity of light and the amount of illumination of the surface area of the object.
In photometry, “luminance” is the density of luminous intensity in a specified direction, but it is often misunderstood as illuminance.… Read More
Enclosed fixtures are dust-proof luminaires that can prevent dust with certain specific attributes or characteristics from entering into it in dusty environments. At the same time, this kind of lamp is waterproof and solid.
There are two general types of electric light sources: one is a heat radiation light source, such as an incandescent lamp; the other is a gas discharge light source, such as a fluorescent lamp, high and low pressure sodium lamps, etc.… Read More
The brightness of the LED lamp is determined by the working current. The larger the current, the brighter it is, but each LED has a rated working current. For example, the working current of ordinary white light small LEDs is about 25MA. If the current exceeds Ratings can cause premature LED decay or damage. Each color of the LED light requires a voltage, not to increase the voltage if you want to increase the brightness.… Read More
A qualidade da iluminação do campo de futebol depende principalmente do nível de iluminação, iluminação média e controle de brilho. Os níveis de iluminação exigidos por atletas e espectadores são diferentes e, para atletas, os níveis de iluminação exigidos são relativamente baixos. No entanto, para que o público assista ao jogo, a iluminação precisa aumentar à medida que aumenta a distância de visualização.… Read More
RGB LED lights are made by mixing red, green and blue. The three primary colors are combined with bai for imaging. In addition, there are blue LEDs with yellow phosphors, and ultraviolet LEDs with RGB phosphors. The colors of some LED backlight panels are very clear and vivid, even to the level of high-definition TVs. This situation is exactly the characteristic of RGB, which advertises the characteristics of red as red, green as green, and blue as blue.… Read More
Metal halide lamps are an important member of high-intensity gas discharge lamps. With the modernization of our country, especially the rapid development of urbanization, and the continuous improvement of people’s requirements for the quality of lighting, metal halide lamps are Features such as luminous flux, high luminous efficiency, high luminous intensity, high color rendering, multi-tone, multi-variety, and long life are favored by people and will play more and more important roles.… Read More
Stadium lights are mainly used to install multiple lamps on various poles around outdoor basketball courts, tennis courts, badminton courts, and football fields; general basketball court lights, badminton court lights, tennis courts, and 5-person / 7-person football stadium light poles The height is about 8-12 meters. There are 2 to 6 spotlights on each light pole. Standard professional football stadiums and stadiums use 18–40 meters high pole lights as the poles of the lamps.… Read More
