LED Floodlight (LEDDownlight) is also called spotlight, projection lamp, spotlight, etc. It is mainly used for architectural decoration lighting, as well as for commercial space lighting. The decorative components are heavier, and its appearance is round and square. Because it is generally necessary to consider the cause of heat dissipation, so its shape and the traditional floodlights still have some differences.
Second, LED flood light characteristics:
At present, the LED floodlights commonly used in 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 distribute the light emitted by the LEDs twice, that is, two. Sub-optics), there are also a few companies that use 3W or higher power LEDs because of the good heat treatment technology. Suitable for large-scale lighting, lighting, buildings and other lighting.
What other things do you need to pay attention to?
1. High-purity aluminum reflector, the most accurate beam and the best reflection effect.
2. Symmetrical narrow angle, wide angle and asymmetric light distribution system.
3, behind the open type of replacement of the bulb, easy to maintain.
4. The lamps are equipped with scale plates to adjust the illumination angle.
LED floodlights are controlled by built-in microchips. In small-scale engineering applications, they can be used without controllers, enabling dynamic effects such as gradual change, jump, color flicker, random flicker, and gradual transition. They can also be controlled by DMX. Achieve chasing, scanning and other effects. At present, the main application places are probably: single building, exterior wall lighting of the historical building group, light outside the building, indoor partial lighting, green landscape lighting, billboard lighting, medical culture and other special facilities lighting, bar Entertainment atmospheres such as dance halls, etc.
Third, what is the LED floodlight?
The LED floodlight is a point source that can be uniformly illuminated in all directions. Its illumination range can be adjusted arbitrarily and appears as a regular octahedron in the scene. Floodlights are one of the most widely used sources in renderings, and standard floodlights are used to illuminate the entire scene. Multiple floodlights can be applied to the scene to produce better results. The floodlight is one of the most widely used light sources in the renderings. In the scene, multiple floodlights can be used to coordinate the effect to produce better results. It is best to illuminate objects from a specific point in all directions, and use it to analogize 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 color floodlights in the scene over long distances. These floodlights can project darkness and blend on the model. Because the floodlights have a large illumination range, the floodlights are very easy to predict, and there are many auxiliary uses for 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. Produces bright light on the top.
It should be noted that the floodlights cannot be built too much, otherwise the renderings will appear dull and dull. Therefore, in the usual renderings of the renderings, pay more attention to the impact of the lighting parameters and the impact of the bureau on the light perception of the entire rendering scene, and accumulate experience and master the matching skills of the lighting.
Fourth, the characteristics of the floodlight:
Floodlights illuminate objects uniformly from a specific point in all directions, and it is best to use analog lights and candles. Floodlights can be placed anywhere in the scene.
