Floodlights are lamps that specify that the illuminance on the illuminated surface is higher than that of the surrounding environment. Also known as spotlight. Generally, it can aim in any direction and has a structure that is not affected by climatic conditions. It is mainly used for large-area operation sites and mines, building outlines, stadiums, overpasses, monuments, parks and flower beds, etc. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as floodlights. The angle of the projecting light beam is wide or narrow, and the range of variation is between 0° and 180°. Among them, the narrow beam is called a searchlight.
The spotlight is composed of optical parts, mechanical parts and electrical parts.
Floodlights are a commonly used lighting fixture that is characterized by its ability to provide uniform, large-area illumination and is suitable for a variety of applications. The following will introduce the structure, application scenarios, advantages and disadvantages, selection methods and installation methods of floodlights in detail.
1. The structure of the floodlight
Floodlights usually have a metal enclosure with a bulb and reflector inside. The bulb produces light, which is reflected through the reflector to the area that needs to be illuminated. Unlike spotlights, floodlights are reflected by the reflector and scattered evenly in all directions, providing a large area of light.
2. Advantages and disadvantages of floodlights
The advantages of floodlights are mainly manifested in the following aspects: firstly, it can provide large-area, uniform light, suitable for various occasions that require large-area lighting; secondly, the installation position of floodlights is flexible, and the illumination angle and direction can be adjusted according to needs; finally, floodlights have a long service life and low maintenance costs.
However, there are also some drawbacks to floodlights. First, it has a large illumination range, so it is difficult to focus or highlight specific targets, secondly, the brightness of floodlights is usually low, making it difficult to provide sufficient illumination at long distances, and finally, floodlights have relatively high energy consumption and high requirements for energy conservation and environmental protection.
3. How to choose a floodlight
When choosing a floodlight, the following aspects need to be considered: first, the right bulb power and reflector size should be selected according to the application scenario, secondly, the appropriate illumination angle and direction should be selected according to the installation location and illumination target, and finally, the service life and maintenance cost of the floodlight should be considered.
