LED floodlights are also called spotlights, projection lights, spotlights, etc. They are mainly used for architectural decoration lighting and commercial space lighting. They have heavier decorative components and have round and square shapes. Generally, the reasons for heat dissipation must be considered, so its appearance is still somewhat different from traditional floodlights.
LED flood light classification:
1. Rotational symmetry
The luminaire adopts a rotationally symmetric reflector, and the symmetry axis of the light source with rotationally symmetric light distribution is installed along the axis of the reflector. The iso-intensity curves of this kind of lamps are concentric circles. When this type of spotlight is illuminated by a single lamp, an elliptical spot is obtained on the illuminated surface, and the illuminance is uneven; but when multiple lamps are illuminated, the spots are superimposed on each other, which can produce a satisfactory lighting effect. For example, hundreds of rotationally symmetrical floodlights are commonly used in stadiums, and they are installed on high towers around the stadium to obtain high illumination and high uniformity lighting effects.
2. Two symmetrical plane shapes
The iso-intensity curve of this type of projector has two symmetry planes. Most lamps use symmetrical cylindrical reflectors, and install linear light sources along the cylindrical axis.
3. A symmetrical plane shape
The isobaric intensity curve of the luminaire has only one symmetry plane (Figure 2). The luminaire adopts an asymmetric cylindrical reflector or a symmetrical cylindrical reflector plus a grid that restricts light. The most typical is the sharp cut-off block retracted light distribution. This kind of light intensity distribution single lamp can obtain a more satisfactory illuminance distribution.
4. Asymmetrical shape
The iso-intensity curve of this kind of lamps has no symmetry plane. Mainly use mixed light lamps with different types of light sources with large difference in light intensity distribution and special lamps designed according to the specific lighting requirements of the place of use.
LED outdoor solar flood light:
At present, the commonly used outdoor solar flood light 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), and a few companies have chosen 3W or higher power LEDs because of the good heat dissipation technology. Suitable for floodlighting in large occasions.
The outdoor solar 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 the most widely used light source in the production of renderings. Standard floodlights are used to illuminate the entire scene. Multiple floodlights can be used in the scene to produce better results.
Outdoor solar flood light are the most widely used light source in renderings. Multiple outdoor solar flood light can be used in the scene to coordinate their effects to produce better effects. It is to illuminate the object uniformly in all directions from a specific point. It is best to use it as an analogy to light bulbs and candles. Floodlights can be placed anywhere in the scene.
For example, it can be placed outside the camera 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 this kind of light has many auxiliary uses, 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 outdoor solar flood light cannot be built too much, otherwise the renderings will appear dull 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.
Features of outdoor solar flood light:
Under small current, the temperature rise of outdoor solar flood light is not obvious. If the ambient temperature is high, the dominant wavelength of the LED floodlight will be red-shifted, the brightness will decrease, and the uniformity and consistency of the luminescence will deteriorate. In particular, the temperature rise of dot matrix and large display has a more significant impact on the reliability and stability of outdoor solar flood light. So the heat dissipation design is very important.

The difference between LED spotlights and outdoor solar flood light
The difference between spotlights and outdoor solar flood light is not only reflected in the visual effects of lighting, but also in the use of floodlights and floodlights.
The difference between floodlights and outdoor solar flood light is that floodlights cannot be built too much, so that the visual effect will appear dull and dull. In the production, pay more attention to the lighting parameters and the light perception of the entire rendering scene. The matters needing attention for the floodlight are: the most accurate beam, high-purity aluminum reflector, the best reflection effect, symmetrical narrow-angle, wide-angle, and asymmetrical light distribution system. Theoutdoor solar flood light fixtures are equipped with scale plates for easy adjustment. Illumination angle.
The difference between floodlights and outdoor solar flood light is also reflected in the range of illumination between the two. Floodlights are also called projection lights, spotlights, spotlights, etc. They are mainly used for architectural decoration lighting and commercial space lighting. Sexual components are heavier, and there are more styles in styling design. Floodlight is a point light source that can evenly illuminate all places in all directions, and its illumination range can be adjusted arbitrarily. Standard floodlights can be used to illuminate the entire scene.
