In contact with LED equipment, we sometimes encounter LED flood light and LED flood light two different devices. What is the difference between them? Please see the following description:
LED cast light, 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 round of the side, because Generally have to consider the reasons for heat, so its shape and the traditional cast light or there are some differences.
LED Flood Light Features:
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.
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.
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.
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.
LED flood light and floodlight difference
The difference between floodlight and spotlight is not only reflected in the visual effects of lighting, but also in the use of floodlights and spotlights. Floodlight and flood light is the difference between the floodlight can not be established too much, so that the visual effects will appear dull and dull, in the production of more attention to the light parameters and the effect of the scene effect of the scene. Spotlights need to pay attention to the matter: the beam of the most accurate, high-purity aluminum reflector, the best reflection, symmetrical narrow angle, wide angle and asymmetric light distribution system, cast light lamps are attached to the scale board to facilitate the adjustment Angle of exposure.
Floodlight and the difference between the spotlight is also reflected in the range between the two, the cast light is called the projection lamp, spotlight, spotlights, mainly used for architectural lighting and commercial lighting, its decoration Sexual components heavier, in the design of more types of style. Floodlight is a place to all directions in all directions uniform light source, the irradiation range can be adjusted, the standard floodlight can be used to illuminate the entire scene.
