1、 What is an LED floodlight?
Led downlight is also called spotlight, projector, spotlight and so on. It is mainly used for building decoration lighting and commercial space lighting. The decorative components are relatively heavy, and its shape is round and square, because the reason of heat dissipation must be considered generally, so its appearance is different from the traditional projector.
2、 Characteristics of LED floodlight:
At present, 1W high-power LED is basically selected as the common LED floodlight in the market (each LED element will be equipped with a high-efficiency lens made of PMMA, and its main function is to distribute the light emitted by LED for secondary distribution, that is, secondary optics). A few companies choose 3W or higher power LED because of good heat dissipation technology. Suitable for large-scale occasion lighting, building lighting and so on. What else should we pay attention to?

High purity aluminum reflector, the most accurate beam, the best reflection effect.
2. Symmetrical narrow angle, wide angle and asymmetric light distribution system.
3. Back open replacement bulb, easy to maintain.
4. All lamps and lanterns are equipped with a scale plate to facilitate the adjustment of the illumination angle. LED projection lamp can be used without a controller in small-scale engineering applications through the control of a built-in microchip. It can achieve dynamic effects such as gradual change, jump change, color flicker, random flicker, gradual change and alternation. It can also achieve chase, scanning and other effects through the control of DMX. At present, its main application places are probably these: single building, external wall lighting of historical buildings, internal light and external light of buildings, indoor partial lighting, green landscape lighting, billboard lighting, medical culture and other special facilities lighting, bar, dance hall and other entertainment places atmosphere lighting, etc.
3、 What is led floodlight
Led floodlight is a kind of point light source which can irradiate uniformly in all directions. Its irradiating range can be adjusted arbitrarily, and it is a picture of octahedron in the scene. Floodlights are the most widely used light source in the production of renderings. Standard floodlights are used to illuminate the whole scene. Multiple floodlights can be used in the scene to produce better results. Floodlight is the most widely used light source in renderings. Multiple floodlights can be used to coordinate in the scene to produce better results. It is the best way to use it to simulate a light bulb or candle. Omni lights can be placed anywhere in the scene. For example, it can be placed outside the camera range, or inside the object. It is common to use a lot of different color floodlights at a long distance in a scene. These floodlights can cast shadows and mix them on the model. Due to the large range of floodlights, the effect of floodlights is very easy to predict, and this kind of light has many auxiliary uses. For example, placing floodlights near the surface of an object will produce bright light on the surface of the object.
It should be noted that the floodlight cannot be built too much, otherwise the effect picture will appear dull and rigid. Therefore, we should pay more attention to the influence of lighting parameters and layout on the lighting sense of the whole scene in the production of ordinary renderings, accumulate more experience and master the matching skills of lighting.
4、 Characteristics of floodlights:
Floodlights are used to irradiate objects uniformly in all directions from a specific point of view. It is best to use them to analogy light bulbs and candles. Omni lights can be placed anywhere in the scene. For example, it can be placed outside the camera range, or inside the object. It is common to use a lot of different color floodlights at a long distance in a scene. These floodlights can cast shadows and mix them on the model. Due to the large range of floodlights, the effect of floodlights is very easy to predict, and this kind of light has many auxiliary uses. For example, placing floodlights near the surface of an object will produce bright light on the surface of the object.
