What is an LED flood light?
LED floodlight (LED Downlight) also known as spotlights, projection lamps, spotlights, etc., mainly used for building decoration lighting purposes, as well as commercial space lighting, decorative elements heavier, the appearance of a circle also has Side, because generally have to consider the reasons for heat, so its shape and the traditional cast light or there are some differences.
Second, LED cast light characteristics:
Currently on the market commonly used LED flood light is basically selected 1W high power LED (each LED element will be made with a PMMA made of high efficiency lens, its main function is the secondary distribution of LED light, that is, two Sub-optical), there are a small number of companies because the cooling technology is handled well, and the choice of 3W or even higher power LED. Suitable for large occasions cast light lighting, buildings and other lighting.
What do you need to pay attention to?
1, high purity aluminum reflector, the most accurate beam, the best reflection.
2, symmetrical narrow angle, wide angle and asymmetric distribution system.
3, behind the open replacement lamp, easy maintenance.
4, lamps are equipped with a dial to facilitate the adjustment of the angle of exposure. The following are the same as the "
LED cast light through the built-in micro-chip control, in small engineering applications, no controller can be used to achieve the gradient, jump, color flicker, random flicker, gradient alternation and other dynamic effects can also be controlled by DMX, To achieve chase, scan and other effects. At present, the main application places are probably these: single building, historical buildings outside the wall lighting, building light through the lighting, indoor local lighting, green landscape lighting, billboard lighting, medical culture and other specialized facilities lighting, Ballroom and other entertainment venues lighting and so on.
What is LED floodlight?
LED floodlight is a point of light can be uniformly illuminated in all directions, its range of illumination can be adjusted in the scene as a positive octahedral display. Floodlights are the most widely used in the production of a light source, the standard floodlights used to illuminate the entire scene. Multiple floodlights can be used in the scene to produce better results. Floodlight is the most widely used in the effect of a light source, the scene can be used to coordinate the role of multiple floodlights to the birth of a better effect. From a specific point to the direction of uniform irradiation of objects, use it to analog light bulbs and candles better. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the scope of the camera, or inside the object. It is common to use many different colors of floodlights in the scene. These floodlights can be darkly projected and mixed on the model. As the floodlight range is relatively large, the floodlight effect is very easy to predict, and this light there are many auxiliary purposes, for example, the floodlight placed near the surface of the object, it will be in the surface of the object To produce bright light.
It should be noted that the floodlight can not be established too much, otherwise the effect will appear dull and dull. So in the usual effect of the production map, and more attention to experience the lighting parameters and layout of the effect of the scene effect of the scene, the accumulation of experience, master the light with the skills.
Fourth, the characteristics of floodlights:
The floodlights illuminate objects evenly from a specific point in all directions, and it is better to use it to compare bulbs and candles. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the scope of the camera, or inside the object. It is common to use many different colors of floodlights in the scene. These floodlights can be darkly projected and mixed on the model. As the floodlight range is relatively large, the floodlight effect is very easy to predict, and this light there are many auxiliary purposes, for example, the floodlight placed near the surface of the object, it will be in the surface of the object To produce bright light.
