LED spotlights 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:
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. This kind of light intensity distribution single lamp can obtain a more satisfactory illumination distribution.
2. 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.
There is no symmetry plane for the iso-intensity curve of this kind of lamps. 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.
4. Rotational Symmetry
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.
LED Flood Light Features:
At present, the commonly used LED floodlights on the market are basically 1W high-power LEDs. (Each LED element will have a high-efficiency lens made of PMMA. Its main function is to distribute the light emitted by the LED twice. 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 project lighting and building lighting.
