What is the difference between LED flood light and LED flood light

2020-04-03

LED floodlights are also called spotlights, spotlights, spotlights, etc. They are mainly used for architectural decorative lighting and commercial space lighting. The decorative components are heavy. Generally, it is necessary to consider the reasons for heat dissipation, so its shape is still different from that of traditional floodlights.

LED flood light classification:
Rotationally symmetric
The lamp uses a rotationally symmetric reflector, and the symmetry axis of the light source with rotationally symmetrical light distribution is installed along the axis of the reflector. The iso-intensity curve of these lamps is concentric circles. When this type of flood light is illuminated by a single lamp, an elliptical light spot is obtained on the illuminated surface, and the illumination is uneven; but when multiple lights are illuminated, the light spots are superimposed on each other to produce a satisfactory lighting effect. For example, hundreds of rotationally symmetrical floodlights are commonly used in stadiums and installed on high towers around the stadium to obtain high-illumination and high-uniformity lighting effects.

Two symmetrical planar shapes
The iso-intensity curve of this type of flood light has two symmetrical planes. Most of the lamps use symmetrical cylindrical reflectors, and the linear light source is installed along the cylindrical axis.
A symmetrical plane

The isoluminance curve of the luminaire has only one plane of symmetry. The luminaire uses an asymmetric cylindrical reflector or a symmetrical cylindrical reflector plus a grid plate that restricts light. The most typical is a sharp cut-off block-type light distribution. Such a light intensity distribution single lamp can obtain a more satisfactory illumination distribution.

Asymmetry
The iso-intensity curve of this type of luminaire does not have a plane of symmetry. It is mainly mixed light lamps with different types of light sources with large differences in light intensity distribution and special lamps designed according to the specific lighting requirements of the place of use.

LED Flood Light Features:
At present, the commonly used LED flood lights on the market are basically 1W high-power LEDs (each LED element will have a high-efficiency lens made of PMMA, and its main function is to distribute the light emitted by the LED twice, that is, two Sub-optical), there are a few companies that use 3W or higher power LEDs because of good heat dissipation technology. It is suitable for large-scale occasions, such as floodlighting and building lighting.
What else do you need to pay attention to?
1. High-purity aluminum reflector, the most accurate light beam, the best reflection effect.
2. Symmetric narrow, wide and asymmetric light distribution systems.
3. Back-open replacement lamp, easy maintenance.
4. The lamps are equipped with scale plates for easy 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 flicker, random flicker, and gradual alternation. It can also be controlled by DMX. Achieve chase, scan and other effects. At present, its main application places are probably these: individual buildings, exterior wall lighting of historical buildings, interior and exterior transparent lighting of buildings, indoor local lighting, green landscape lighting, billboard lighting, medical and cultural facilities, bars, Atmospheric lighting in entertainment venues such as ballrooms.

LED flood light
LED flood light is a kind of point light source that can illuminate evenly in all directions. Its irradiation range can be adjusted arbitrarily, and it appears as a regular octahedron in the scene. Flood light is the most widely used light source in the production of renderings. Standard flood lights are used to illuminate the entire scene. Multiple flood lights can be applied to the scene to produce better results.

Flood light is the most widely used light source in the effect map. Multiple flood lights can be used to coordinate the scene to produce better results. It is to illuminate objects uniformly from a specific point in all directions. 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 range of the camera or inside an object. It is common to use many different colored floodlights at long distances in a scene. These flood lights can cast shadows and mix on the model. Because the range of the floodlight is relatively large, the effect of the floodlight is very easy to predict, and there are many auxiliary uses for this kind of light. Produces a bright light.

It should be noted that the floodlight cannot be built too much, otherwise the rendering will look dull and dull. Therefore, in the production of the usual renderings, pay more attention to the effects of lighting parameters and layout on the light effect of the entire renderings scene, accumulate more experience, and master the lighting matching skills.

Basic Information:
Features of flood light:
Under low current, the temperature rise of LED flood light is not obvious. If the ambient temperature is high, the dominant wavelength of the LED flood light will be red-shifted, the brightness will be reduced, and the uniformity and consistency of light emission will be deteriorated. In particular, the temperature rise of the dot matrix and large display has a more significant impact on the reliability and stability of LED floodlights. So thermal design is critical.

Floodlights illuminate objects evenly from a specific point in all directions, and it is best to use them to compare light bulbs and candles. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the range of the camera or inside an object. It is common to use many different colored floodlights at long distances in a scene. These flood lights can cast shadows and mix on the model. Because the range of the floodlight is relatively large, the effect of the floodlight is very easy to predict, and there are many auxiliary uses of this light. For example, if the floodlight is placed near the surface of the object, it will be on the surface of the object. Produces a bright light.

The difference between LED flood light and flood light
The difference between floodlights and floodlights is not only reflected in the lighting visual effects, but also the precautions in the use of floodlights and floodlights are different.

The difference between a flood light and a flood light is that the flood light cannot be built too much, so that the visual effect will be dull and dull. Pay attention to the lighting parameters and the light effect on the entire rendering scene in the production. The matters needing attention for the flood light are: the most accurate light beam, high-purity aluminum reflector, the best reflection effect, symmetrical narrow-angle, wide-angle, and asymmetric light distribution system. The flood-light lamps are equipped with scale plates for easy adjustment. Irradiation angle.

The difference between floodlights and floodlights is also reflected in the range of illumination between them. Floodlights are also known as projection lights, spotlights, spotlights, etc. They are mainly used for architectural decorative lighting and commercial space lighting. The sexual component is heavier, and there are more styles in the design. A flood light is a type of point light source that can illuminate evenly everywhere in all directions. Its irradiation range can be adjusted arbitrarily. A standard flood light can be used to illuminate the entire scene.
