LED floodlights are also called spotlights, projection lamps, spotlights, etc., mainly used for architectural decorative lighting, as well as commercial space lighting, decorative components are heavier, and their appearance is round and square, because Generally, it is necessary to consider the cause of heat dissipation, so its shape is still different from the traditional spotlight.
LED flood light classification:
1, rotational symmetry
The luminaire employs a rotationally symmetric reflector and mounts the axis of symmetry of the source with a rotationally symmetric light distribution along the axis of the reflector. The iso-intensity curves of such lamps are concentric. In this type of spotlight, when the single lamp is illuminated, an illuminating spot is obtained on the illuminated surface, and the illuminance is not uniform; however, when the multi-lamp is illuminated, the spots are superimposed on each other to produce a satisfactory illumination effect. For example, hundreds of rotating symmetrical spotlights are commonly used in stadiums and installed on high towers around the stadium to achieve high illumination and high uniformity.
2, two symmetrical plane shapes
The iso-intensity curve of this type of floodlight has two planes of symmetry. Most of the luminaires use a symmetrical cylindrical reflector and the linear light source is mounted along the cylinder axis.
3. A symmetrical plane shape
The equal intensity curve of the luminaire has only one symmetry plane, and the luminaire uses an asymmetric cylindrical reflector or a symmetrical cylindrical reflector plus a grid that limits the light. The most typical is the sharp cut-off block retracting light distribution. Such a light intensity distribution single lamp can obtain a satisfactory illumination distribution.
4, asymmetric shape
The iso-intensity curves of such lamps do not have a plane of symmetry. Mainly used for mixed light fixtures with different types of light sources with different light intensity distributions and special lamps designed according to the specific lighting requirements of the place of use.
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, the most accurate beam and the best 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 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.
