When contacting LED devices, we sometimes encounter two different devices, high-power LED floodlights and LED floodlights. So what is the difference between them? Please see the following introduction:
High-power LED flood light LEDFlood Light, also known as LED spotlight, LED projection light. LED floodlights are controlled by built-in microchips. There are two types of products, one is a power chip combination, and the other is a single high-power chip. The former has stable performance, and the single high-power product has a large structure. Range of light-emitting illumination, the latter can achieve high power, can carry out long-distance large-area projection.
LED floodlights make lamps that specify illumination on the illuminated surface higher than the surrounding environment, also known as spotlights. Typically, it can be aimed in any direction and has structures that are unaffected by climatic conditions. Mainly used for large-area job mines, building outlines, stadiums, overpasses, monuments, parks and flower beds. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as floodlights. Therefore, its shape is still different from the traditional spotlights.
LED flood light features:
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, precise beam and good reflection effect.
2. Symmetrical narrow angle, wide angle and asymmetric light distribution system.
3, open behind the 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, historical building group exterior wall lighting, building exterior light, indoor partial lighting, green landscape lighting, billboard lighting, medical culture and other special facilities lighting, bars, Entertainment venues such as dance halls, etc.
LED flood light
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 a wide range of light sources used in renderings, and standard floodlights are used to illuminate the entire scene. Multiple floodlights can be applied to the scene to produce better results. Floodlights are a kind of light source that is widely used in renderings. In the scene, multiple floodlights can be used to coordinate the effects to produce better results. It is a uniform illumination of objects from a specific point in all directions, and it is commonly used 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 colors of floodlights in the scene. 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, pay more attention to the influence of the lighting parameters and layout on the light perception of the entire rendering scene, accumulate experience and master the matching skills of the lighting.
Characteristics of the floodlight:
Floodlights illuminate objects uniformly from a specific point in all directions, and are much better than 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.

The difference between LED floodlights and floodlights
1. The difference between a floodlight and a floodlight is the angle of projection of the light, but now many people are confused because there is no standard to distinguish it. The beam of the floodlight is more uniform, that is, the light source is more concentrated in the building. Object or landscape object, but now it can also be made astigmatism, followed by floodlights, his illumination range is relatively large.
2, can be arbitrarily adjusted, in fact, here is the floodlight is a category inside the floodlights, here you estimate that you have a clearer understanding! If there is no uniform standard, the LED floodlights are basically based on the approximate shape parameters, or the appearance adjustment, so that he can choose more heat dissipation problems, and the optical characteristics of the reasonable heat dissipation structure LED For glare problems, it is necessary to have a light-transmissive lampshade to form a surface light source to some extent. Nowadays, many materials are added by sanding or adding materials. With the development of these years, the light transmission performance is further improved. The SMD LEDs are mostly low-voltage drives that use aluminum substrates for heat dissipation. The LED floodlights currently used are not specifically designed for lighting, and some are used to create good projection effects.
