What kind of light is a floodlight? What does floodlighting mean?
The LED floodlight is a point light source that can evenly illuminate in all directions
Its illumination range can be adjusted arbitrarily, and it appears as a regular octahedron icon in the scene. LED Floodlight is the most widely used light source in the production of renderings. Standard floodlights are used to illuminate the entire scene. Multiple floodlights can be used in the scene. In order to produce a better effect, the light bulb for shooting is installed in a large reflecting umbrella for use as a high-brightness diffused light source. Although it is indispensable for indoor lighting, it can also be regarded as one of the light sources with good lighting effects for ordinary amateur indoor photography. Therefore, floodlights are often used in billboards, highways, railway tunnels, bridges and culverts, and other scenes.
So what does floodlighting mean?
Floodlighting refers to a lighting method that makes the brightness of a specific lighting area or a specific visual target much higher than other targets and surrounding areas. In aircraft cabin lighting, it refers to the use of floodlights to illuminate the instrument panel and other large areas of the lighting state. It is often used in the lighting design of advertisements or shop windows. It is also often used as auxiliary lighting and emergency lighting. It should be used to prevent glare from interfering with visual tasks.
With multiple of optic lens design, the Nova-UM series floodlight can hit requirements for many different applications
What are the technical requirements for floodlighting?
1. Incident angle
It is the shadows that highlight the ups and downs of the facade. Therefore, the lighting should always provide surface imaging. The light shining on the facade at a right angle will not form shadows and make the surface appear flat. The size of the shadow depends on the surface undulations and the angle of incidence of the light. The average illuminating direction angle should be 45°. If the fluctuation is very small, this angle should be greater than 45°.
2. Illumination direction
In order to make the surface lighting look balanced, all shadows should be cast in the same direction, and all lamps that illuminate the surface in a projection area should have the same projection direction. For example, if two lights are symmetrically aimed at the vertical direction of a surface, the shadows will be reduced and chaos may appear. Therefore, you may not be able to see the surface undulations clearly. However, large protrusions can produce large dense shadows. In order to avoid destroying the integrity of the facade, it is recommended to provide weaker lighting at an angle of 90° to the main lighting to weaken the shadows.
In order to see shadows and surface undulations, the lighting direction should be different from the viewing direction, and the angle between these two directions should be at least 45°. However, for monuments that can be seen from several places, it is impossible to strictly abide by this rule. The main observation point should be selected, and this observation direction should be given priority in lighting design.
Therefore, floodlights are commonly used lamps in floodlighting.
