1. What is LED flood light?
LED downlights are also called spotlights, projection lights, spotlights, etc. They are mainly used for architectural decorative lighting and commercial space lighting. They have heavier decorative components and have round and round shapes. Square, because the heat dissipation is generally considered, there are still some differences between its appearance and traditional floodlights.

Two, LED flood light characteristics:
At present, the commonly used LED floodlights on the market basically use 1W high-power LEDs (each LED component will have a high-efficiency lens made of PMMA, and its main function is to secondarily distribute the light emitted by the LED, which is two Secondary optics), a few companies have chosen 3W or higher power LEDs because of the good heat dissipation technology. It is suitable for large-scale occasions, lighting, buildings and other lighting.

What else should be paid attention to for the flood light?
1. High-purity aluminum reflector, precise beam and good reflection effect.
2. Symmetrical narrow-angle, wide-angle and asymmetric light distribution systems.
3. The light bulb can be replaced with an open-back type, which is easy to maintain.
4. The lamps are all attached with a scale plate to facilitate the adjustment of the irradiation angle.  

The LED flood light is controlled by a built-in microchip. In small engineering applications, it can be used without a controller. It can achieve dynamic effects such as gradation, jump, color flashing, random flashing, and gradual alternation. It can also be controlled by DMX. Achieve effects such as chasing and scanning. At present, its main application places are probably these: single buildings, 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 facility lighting, bars, Atmosphere lighting in dance halls, etc.

Three, what is LED flood light
The LED flood light is a point light source that can illuminate uniformly in all directions. Its illumination range can be adjusted arbitrarily, and it appears as a regular octahedron icon in the scene. Floodlights are a widely used light source in the production of renderings, and standard floodlights are used to illuminate the entire scene. Multiple floodlights can be used in the scene to produce better results. Floodlights are a kind of light source that is widely used in renderings. Multiple floodlights can be used in the scene to coordinate their effects to produce better results. It is to illuminate the object uniformly in all directions from a specific point. It is best to use it as an analogy to a light bulb and a candle. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the camera's range or inside an object. It is common to use many different colored floodlights in the scene at a distance. These floodlights can project and blend the darkness on the model. Because the floodlight has a relatively large illumination range, the illumination effect of the floodlight is very easy to predict, and there are many auxiliary uses of this kind of light, for example, if the floodlight is placed close to the surface of the object, it will be on the surface of the object. It produces a bright light.

It should be noted that floodlights cannot be built too much, otherwise the renderings will appear flat and dull. Therefore, in the usual rendering of renderings, pay more attention to the impact of lighting parameters and layout on the light perception of the entire renderings scene, accumulate more experience, and master the lighting matching skills.

Fourth, the characteristics of floodlights:
Floodlights illuminate objects uniformly in all directions from a specific point. It is the best analogy to light bulbs and candles. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the camera's range or inside an object. It is common to use many different colored floodlights in the scene at a distance. These floodlights can project and blend the darkness on the model. Because the floodlight has a relatively large illumination range, the illumination effect of the floodlight is very easy to predict, and there are many auxiliary uses of this kind of light, for example, if the floodlight is placed close to the surface of the object, it will be on the surface of the object. It produces a bright light.
