Led floodlights are luminaires that specify that the illuminance of the illuminated surface is higher than the surrounding conditions. Also called a spotlight. In general, it can target any target and has a structure that is not affected by weather conditions. Mainly used for large-area work sites, building outlines, sports fields, overpasses, monuments, parks, flower beds, etc. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as Led floodlights. The angle of the outgoing beam of the LED flood light is wide or narrow, and the conversion ratio is between 0° and 180°. Among them, the narrow beam is called searchlight.
Led flood light consists of three parts: optical part, mechanical part and electrical part. The optical elements are mainly reflectors and light-limiting shutters. The main mechanical parts include a casing, a focusing mechanism for fixing and adjusting the position of the light source, a bracket and a base for fixing the light, and a part for adjusting the angle of the projection target of the light beam. . For most enclosed Led floodlights, the mechanical parts include protective glass and various seals. According to the needs of use, some also have a metal grille. The high-performance Led floodlight is also equipped with an air filter. Electrical components include ballasts, capacitors, triggers, etc.
Led floodlight manufacturers use torsionally symmetrical reflectors, install the light source symmetry axis, and the torsionally symmetrical light propagates along the reflector axis. The iso-intensity curves of such lamps are concentric circles. In this case, when the LED flood light is illuminated by a single lamp, an oval light spot is obtained on the light receiving surface, and the illumination is uneven; but when it is illuminated by multiple lamps, the light spots are superimposed on each other, which can produce contrasting lighting. Effect. For example, hundreds of torsionally symmetrical Led floodlights are often used in sports fields, mounted on high towers around the sports fields to achieve high illuminance and high average lighting effects.
Led floodlights can be installed and used alone, or a combination of multiple lights can be installed on a light pole above 20m to form a high-pole light assembly. In addition to beautiful appearance, centralized protection and maintenance, and reduction of light poles and floor space, this assembly method also has a great advantage in that it has a strong lighting function. When the light is projected from a height, the space of the situation is bright and the light cage covers a large area, giving a day-like feeling, so it has a higher lighting quality and visual effect.
The role of the power supply is also the affected sector of the LED flood light manufacturer's flood light. Generally, a conventional 1W high-power power supply provides a current of 350mA; first, the power supply must ensure that when the output current is 350mA/W, the LED flood light can display higher brightness.
At the same time, in the light effect part, some functional parameters of the power supply used by the floodlight can also be displayed. From the first point of view, the higher the efficiency, the higher the light efficiency, the better. A good power supply efficiency is generally above 90%, and there is a power factor that can reach a power factor of more than 90%.
In the process of understanding the led flood light, we found that its anti-vibration design is very good, so in the process of using it, don't worry that it will cause damage and cost. Add money, this aspect is a job you don't have to worry about at all.
