led floodlights are lamps that specify a higher illumination on the illuminated surface than the surrounding environment. Also known as spotlight. Usually, it is able to aim in any direction and has a structure that is not affected by climatic conditions. It is mainly used in large area mines, building profiles, stadiums, overpasses, monuments, parks and flower beds. Therefore, almost all outdoor use of large area lighting lamps can be regarded as led floodlights. The Angle of the beam of the led beam is wide and narrow, and the range of change is between 0° and 180°, of which the beam is particularly narrow, called the searchlight.
The mechanical parts are mainly the shell, and the focusing mechanism for fixing and adjusting the position of the light source, the support for fixing the luminaire, the base and the parts with Angle indications for adjusting the direction of the luminaire beam projection. For most of the closed led floodlights, mechanical components and protective glass and various sealing rings. According to the needs of the use of the environment, some also have metal mesh cover. A good performance led floodlight is also equipped with an air filter. Electrical components are mainly ballasts, capacitors, triggers (according to the needs of the light source) and so on.
Urban lighting manufacturers use rotary symmetric reflectors, and the symmetry axis of the light source with rotary symmetric light distribution is installed along the reflector axis. The isointensity curve of such lamps is concentric circles. When this form of led floodlight is illuminated by a single lamp, the elliptic spot is obtained on the illuminated surface, and the illumination is uneven; However, when multiple lights are illuminated, the spots are superimposed on each other, which can produce satisfactory lighting effects. For example, hundreds of rotating symmetrical led floodlights are commonly used in the stadium, which are installed on the high tower around the stadium to obtain high illumination and high uniformity lighting effects.
led floodlights can be used for single installation, or multiple lights can be combined to be installed on a pole above 20m to form a high-pole lighting device. In addition to the beautiful shape of this device, can be centralized maintenance, reduce the lamp pole and occupy an area, the biggest advantage is that the lighting function is strong. When the light is projected from a height, the spatial brightness of the environment is high, and the light coverage is large, giving people a feeling similar to the day, so there is a high lighting quality and visual effects.
led floodlight bright color, good monochromaticity, soft light, low power, long life, light up to 50,000 hours. And its LEDled lamp body is small, easy to hide or install, not easy to damage, no thermal radiation, advantageous to protect the illuminated object, a wide range of applications. The lamps are equipped with a scale plate to facilitate adjustment of the irradiation Angle, and the LEDled light can be used without a controller in small engineering applications through the control of a built-in microchip, and can achieve dynamic effects such as gradual change, jump, color flicker, random flicker, gradual change, etc., and can also achieve chase, scanning and other effects through DMX control.
