What are the advantages of led billboard light?
Led billboard light is one of many forms of outdoor advertising, which is deeply loved by advertisers. Today, I will find the editor of Guangwang to share with you the knowledge about LED light billboards. led billboard light uses led cold light source, does not contain mercury and other toxic substances in traditional advertising light sources, and is more environmentally friendly. Longer lifespan, traditional metal halide advertising lights have a lifespan of 7000-10000 hours, while led billboard light lifespans are as high as 100,000 hours. Traditional metal halide advertising lights are greatly disturbed by power supply stability, and the fluctuation will affect the life of triggers, ballasts and other devices. The led billboard light has a simple internal structure and stronger stability.

Common led floodlight classification introduction
The common types of LED floodlights are as follows: 1. Rotational symmetry The luminaire adopts a rotationally symmetric reflector, and the axis of symmetry of the light source with rotationally symmetric light distribution is installed along the axis of the reflector. The iso-intensity curves of such lamps are concentric circles. When this type of flood light is illuminated by a single lamp, an elliptical light spot is obtained on the illuminated surface, and the illumination is uneven; but when multi-light illumination is used, the light spots are superimposed on each other, which can produce a satisfactory lighting effect. For example, hundreds of rotationally symmetrical floodlights are commonly used in stadiums, which are installed on high towers around the stadium to obtain high illumination and high uniformity lighting effects. 2. Two symmetrical planes The equal intensity curve of this type of floodlight has two symmetry planes. Most of the lamps use symmetrical cylindrical reflectors, and the linear light sources are installed along the axis of the cylindrical surface. 3. A symmetrical plane The iso-intensity curve of a luminaire has only one plane of symmetry. The luminaire uses asymmetric cylindrical reflectors or symmetrical cylindrical reflectors plus grids that limit light. The most typical is the sharp cut-off block retraction light distribution. This kind of light intensity distribution single lamp can obtain a relatively satisfactory illuminance distribution. 4. Asymmetrical shape The iso-intensity curve of this type of luminaire has no plane of symmetry. It mainly uses mixed light lamps of different types of light sources with large differences in light intensity distribution and special lamps designed according to the specific lighting requirements of the place of use.

About the advantages of led floodlights
Advantage 1: Irradiation angle adjustment The LED floodlight is actually a spotlight, and its illumination angle can be adjusted, so its use is more flexible. And the general floodlight will have an angle adjustment scale plate, and adjusting according to the mark on the scale plate can make the installation more accurate. Advantage 2: Wide range of applications Compared with other lighting fixtures, the size of LED floodlights is very small, so it can meet the needs of a wider range of installation sites. The lamp is not prone to damage during use, and it will not heat up due to long use, so its service life is relatively long. Advantage three: good lighting effect Since the floodlight is actually a spotlight and has the function of spotlighting, the effect of the light emitted is very good. The color of the light is bright, and the color purity is high, not dazzling, and the light is soft. In addition, because the LED floodlight has high luminous efficiency and low power consumption, it is very power-saving during use.

Introduction to application scenarios of LED floodlights
What is LED floodlight? It is mainly used for architectural decorative lighting and commercial space lighting. The decorative components are heavier, and its appearance is round or square, because generally the reasons for heat dissipation must be considered. , so its shape is still somewhat different from the traditional floodlight. The LED flood light is controlled by the built-in microchip. In small engineering applications, it can be used without a controller, and can realize dynamic effects such as gradient, jump, color flashing, random flashing, and gradient alternation. It can also be controlled by DMX. Realize the effect of chasing, scanning and so on. Its main application places are probably as follows: single building, exterior wall lighting of historical buildings, building interior and exterior lighting, indoor local lighting, green landscape lighting, billboard lighting, medical and cultural and other specialized facilities lighting, bars, dance halls, etc. Atmosphere lighting in entertainment venues, etc.

Product Features of led floodlight
Under low current, the temperature rise of LED floodlight is not obvious. If the ambient temperature is high, the dominant wavelength of the LED floodlight will be red-shifted, the brightness will decrease, and the uniformity and consistency of the light emission will become worse. In particular, the temperature rise of dot matrix and large display screens has a more significant impact on the reliability and stability of LED floodlights. So the heat dissipation design is very important. Floodlights illuminate objects evenly in all directions from a specific point, and it's a perfect analogy to light bulbs and candles. Omnilights can be placed anywhere in the scene. For example, it can be placed outside the camera range, or inside an object. It is common to use many floodlights of different colors at a distance in a scene. These floodlights can cast and blend shadows on the model. Due to the large illumination range of the floodlight, the illumination effect of the floodlight is very easy to predict, and this kind of light has many auxiliary uses. For example, if the floodlight is placed close to the surface of the object, it will be produces bright light.
