LED flood lights are point sources that illuminate evenly in all directions and can be adjusted in any direction. It is best used as an analogy between a light bulb and a candle. LED flood lights can be placed anywhere in the scene. For example, it can be placed outside the range of the camera or inside the object. Usually, many different colors of floodlights are used at a distance. These floodlights can cast and blend the darkness on the model.
As LED flood lights have a relatively large illumination range, it is easy to predict the illumination effect of the searchlight. And there are many ancillary uses for this light. For example, if the searchlight is placed close to the object’s surface, it will be on the object’s surface. It produces a bright light.
At low currents, the temperature rise of the LED floodlight is not significant. If the ambient temperature is higher, the primary wavelength of the LED floodlight will be red-shifted, the brightness will be reduced, and the uniformity and consistency of the light will be poor. In particular, the temperature rise of the dot matrix and large displays has a more important impact on the reliability and stability of LED floodlights. Therefore, heat dissipation design is essential. 
Working Principle
LED flood lights are the most widely used light source for effects production. A standard LED flood lights is used to illuminate an entire scene. Multiple floodlights can be used in a scene to produce better results. Outdoor LED flood lights are the most widely used light source in rendering. Multiple Outdoor LED flood lights bubs can be used in a scene to coordinate their effects for better results.
Application Areas
The RGB LED Floodlights was widely used in Hotel facade、 square night view、garden lighting、interior decoration、outdoor floodlighting.
Characteristics of LED floodlights:
. high purity aluminum reflector, the most accurate beam and the best reflection effect.
. symmetrical narrow-angle, wide-angle and asymmetrical light distribution system.
.The lamp can be replaced as an open type, easy to maintain.
.The luminaires are equipped with a scale plate for easy adjustment of the lighting angle.
A built-in Bluetooth chip controls smart LED flood lights. In small engineering applications, Is is no need controller. It can use it through smartphone. It can achieve dynamic effects such as fading, jumping, color flashing, random flashing and fading.
The main applications may be: lighting of single buildings, facades of historical buildings, interior and exterior lighting of buildings, local interior lighting, green landscape lighting, lighting of advertising licenses, lighting of medical and cultural and other specialized facilities, ambient lighting of bars, dance halls, entertainment venues, etc.
LED spotlights
LED spotlights are also known as projector lights and spotlights. They are mainly used for architectural decorative lighting and commercial space lighting. They have a heavy decorative component as well as around and square appearance. They also have a more traditional appearance and project light slightly differently due to the need to consider heat dissipation properties.
LED spotlight classification.
.Rotating and symmetrical
Illuminators use a rotating symmetrical reflector, an asymmetrical shaft with a rotating proportional light source mounted along the shaft of the rotating reflector. The isometric curve of this type of lighting is concentric.
When a single lamp illuminates this type of spotlight, an elliptical point is formed on the illuminated surface and the illumination is not uniform. However, when multiple lights are lit, these spots overlap each other and can produce good lighting effects. For example, hundreds of rotating symmetrical floodlights are often used in stadiums and mounted on towers around the stadium to achieve high illumination and high illumination uniformity.
. Two symmetrical planar shapes
The isometric curve of this type of projector has two symmetrical planes. Most luminaires use asymmetrical cylindrical reflector, and the linear light source is mounted along the cylindrical axis.
. Symmetrical flatlines
Lamps have only one symmetrical plane for the isometric curve. The luminaire uses either an asymmetric cylindrical reflector or asymmetric cylindrical reflector with a light limiting grille. Typically a sharp cutoff block is used to constrict the light distribution. This light intensity distribution of the single lamp can obtain a more satisfactory distribution of illumination.
. Asymmetric Shapes
This type of lamp has no symmetrical planes in its isometric curve. Mixed lamps are mainly used, which have different types of light sources with very other light intensity distributions and unique lamps designed to meet the specific lighting requirements of the place of use.
LED spotlight characteristics
LED spotlights mainly use high-power LEDs. Some companies have chosen 3W or higher power LEDs due to proper heat dissipation technology. LED spotlights are suitable for floodlighting in large settings, buildings and another lighting.
What else do I need to know about using LED spotlights?
.High purity aluminum reflector beam is focused for better reflection.
.Symmetrical narrow-angle, wide-angle and asymmetrical light distribution system.
.The bulb can replace with an open type that is easy to maintain.
.The bulb is equipped with a dial for easy adjustment of the lighting angle.
At present, the main application areas of LED spotlights are single buildings、 LED facade lighting、 Historic buildings、interior and exterior lighting of buildings、 interior local lighting、 green landscape lighting、Advertising license lighting、 medical culture and other special facilities lighting、bar atmosphere lighting Entertainment venues, such as ballrooms, etc.
Differences between LED flood lights and spotlights
The difference in use.
You do not need to place too many floodlights, otherwise, the visual effect will become dull; in practice, you need to pay attention to the lighting parameters and light perception of the whole application.
Spotlights are more focused in the direction of the beam and have a graduated plate to adjust the lighting angle.
Differences in range of illumination.
LED flood lights have a wide and even lighting range; LED spotlights, also known as spotlights, have a smaller luminous angle and are relatively more concentrated.
LED floodlight installation tips and notes
Even though LED floodlights are easy to install, they still require some installation techniques and attention, which complement the advantages of LED floodlights. The LED floodlight is equipped with fixing screws, so installation is relatively simple.
Detailed description: Materials required: LED fence light clip, transformer with waterproof function, sub-controller, steps are as follows.
. Install the guardrail on the wall and punch a hole. According to the actual requirements, the spacing should be within 3 cm.
. Take anti-static measures, for example, the workbench should be grounded, wear corresponding static clothing, and take anti-static steps because different LED floodlights have other quality and different anti-static capabilities.
. Pay attention to the airtightness during installation, poor airtightness will directly affect the service life of LED floodlights
The wiring of LED floodlights should not exceed 25 cm, which can extend the power of the transformer accordingly, otherwise, it will affect the brightness.
LED floodlights are widely used, so installation techniques and precautions are very important. Under the correct installation method, LED is a new light source that can ensure the LED floodlight stable, long-term regular operation.
