What are the advantages of LED flood lights
1. Irradiation angle adjustment, LED floodlight is actually a kind of spotlight, so its irradiation angle can be adjusted, so its use is more flexible, and general floodlights will have an angle adjustment scale board, so It can be adjusted more accurately in accordance with the markings on the scale board.
2. The application range is wide. Compared with other lighting fixtures, the size of the LED floodlight is very small, so it can adapt to the needs of a wider range of installation sites, and it is not prone to damage during use. It will heat up because of the long use time, and naturally its service life is relatively long.
3. No controller is needed. Compared with other lighting fixtures, LED floodlights can be used without a controller, and a variety of special illumination effects can be achieved during use, such as the gradual change of light and the change of light color. , Light jump, light flicker, etc. These are high-end dynamic lighting decoration effects that ordinary lamps cannot achieve.
4. The lighting effect is good. Because it is actually a kind of spotlight, which has the function of spotlighting, the lighting effect from the LED floodlight is very good, the color of the light is very bright, and the purity of the color is very high, although The color of the LED floodlight is brighter, but its light is not dazzling at all. On the contrary, it is very soft, which is very suitable for local lighting decoration of the home. In addition, the LED floodlight is also a very energy-saving lighting fixture. It is very power-saving during use, because its power is not high.
Classification and characteristics of LED floodlights
LED flood light classification:
1. A symmetrical plane
There is only one symmetry plane for the isoluminous intensity curve of the luminaire. The luminaire adopts asymmetrical cylindrical reflector or symmetrical cylindrical reflector plus a grid that restricts light. The more typical is the sharp cut-off block retracted light distribution. This type of light intensity distribution single lamp can obtain a more satisfactory illuminance distribution.
2. Two symmetrical plane shapes
The iso-intensity curve of this type of projector has two symmetry planes. Most luminaires use symmetrical cylindrical reflectors, and linear light sources are installed along the cylindrical axis.
3. Asymmetrical shape
The iso-intensity curve of this type of luminaire does not have a plane of symmetry. 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. Rotationally symmetrical shape
The luminaire adopts a rotationally symmetrical 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 curves of this type of lamps are concentric circles. When this type of spotlight is illuminated by a single lamp, an elliptical spot is obtained on the illuminated surface, and the illumination is uneven; but when multiple lamps are illuminated, the spots are superimposed on each other, which can produce a satisfactory lighting effect. For example, hundreds of rotationally symmetrical floodlights are commonly used in stadiums, and they are installed on high towers around the stadium to obtain high-illuminance and high-uniformity lighting effects.
LED flood light characteristics:
At present, the commonly used LED floodlights on the market basically use 1W high-power LEDs (each LED element will have a high-efficiency lens made of PMMA, and its main function is to secondarily distribute the light emitted by the LED, which is two Secondary optics), and a few companies have chosen 3W or higher power LEDs because of the good heat dissipation technology. It is suitable for large-scale occasions, lighting, buildings and other lighting.
