LED floodlights are also known as spotlights, spotlights, spotlights
1. Rotation and symmetry
A rotationally symmetric reflector is selected, and the symmetry axis of the light source with rotationally symmetric light dispersion is arranged along the reflector axis. The iso-intensity curve of this lamp is concentric circles. Factory flood light order
When this type of spotlight is illuminated by a single lamp, an elliptical spot appears on the illuminated surface, and the illumination is uneven; but in the case of multi-lamp illumination, the spots overlap each other, which can produce a satisfactory lighting effect. For example, in a stadium, hundreds of rotationally symmetrical projection lamps are usually used, which are installed on towers around the stadium to obtain high illuminance and high uniformity of illumination.
2. Two symmetrical plane shapes
The iso-intensity curve of this kind of spotlight has two symmetry planes. Most luminaires use a symmetrical cylindrical reflector with a linear light source along the axis of the cylindrical device.
3. Symmetrical plane row
The iso-intensity curve of the luminaire has only one symmetry plane. The luminaire uses a lattice composed of asymmetric cylindrical reflectors or symmetrical cylindrical reflectors with light confinement. The most typical is the sharp cut-off block retracting light distribution. This kind of light intensity dispersion can obtain more satisfactory illuminance dispersion through a single lamp.
4. Asymmetrical shape
The isointensity curve of this lamp has no plane of symmetry. Mainly choose light intensity dispersion mixed light and lamps of different kinds of light sources, according to the specific lighting requirements and planning used.
