The difference between LED floodlights and floodlights

First, what is LED flood light?

LED Downlight (LEDDownlight) is also called Spotlight, Spotlight, Spotlight, etc. It is mainly used for architectural decoration lighting and commercial space lighting. The decorative elements are heavy, and its appearance is round and square. , because generally have to consider the cause of heat, so its shape and the traditional cast light there are still some differences.

Second, LED flood light features:

At present, LED floodlights commonly used in the market basically use 1W high-power LED (each LED element will have a high-efficiency lens made of PMMA, its main function is to secondary distribution of LED light, that is, two Sub-Optical) There are also a few companies that have adopted 3W or higher power LEDs due to good thermal processing. Suitable for large-scale lighting lighting, buildings and other lighting.

What other things need to pay attention to the spotlight?

1, high-purity aluminum reflector, beam the most accurate, best reflection.

2. Symmetric narrow-angle, wide-angle and asymmetric light distribution systems.

3, behind the open bulb replacement, easy maintenance.

4, the lamps are attached with a scale board to adjust the irradiation angle.

The LED flood light is controlled by a built-in microchip and can be used without a controller in a small-scale engineering application, and can achieve dynamic effects such as gradation, jump, color flicker, random flicker, gradual change, etc., and can also be controlled by the DMX. Chasing, scanning and other effects. At present, its main application areas are probably: monolithic buildings, historical buildings, external wall lighting, interior and exterior lighting, indoor lighting, green landscape lighting, billboard lighting, medical and cultural facilities, lighting, bars, Ballroom and other entertainment venue atmosphere lighting and so on.

Third, what is LED flood light?

LED flood light is a point light source that can be uniformly illuminated in all directions. Its illumination range can be arbitrarily adjusted and appears as a positive octahedron in the scene. Floodlights are the most widely used light source in renderings, and standard floodlights illuminate the entire scene. Multiple floodlights can be used in the scene to produce better results. Floodlight is the most widely used light source in the renderings. The scene can be coordinated with multiple floodlights to produce better results. It is a uniform illumination of objects from a specific point in all directions, and it is best to compare light bulbs and candles. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the camera or inside the object. It is very common to use many different colors of floodlights at a distance in the scene. These floodlights can cast shadows and mix on models. Due to the relatively large range of floodlights, the effect of floodlights is very easy to predict, and there are many auxiliary uses for such lights. For example, placing a floodlight near the surface of an object will result in the surface of the object. Produces bright light.

It should be noted that floodlights cannot be built too much, otherwise renderings will appear dull and dull. Therefore, in the usual production of effect maps, pay more attention to the effect of lighting parameters and layout on the overall effect of the effect of the scene, to accumulate experience and master lighting techniques.

Fourth, the characteristics of floodlights:

Floodlights illuminate objects evenly from a particular point in all directions. Using them to compare bulbs and candles is best. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the camera or inside the object. It is very common to use many different colors of floodlights at a distance in the scene. These floodlights can cast shadows and mix on models. Due to the relatively large range of floodlights, the effect of floodlights is very easy to predict, and there are many auxiliary uses for such lights. For example, placing a floodlight near the surface of an object will result in the surface of the object. Produces bright light.
