Application scenarios of LED floodlights
Due to the environmental protection and energy saving, diversified color temperature and long service life of LED flood light lamps, the requirements for the use environment are not high. It can be applied to indoor, outdoor or large public places. Therefore, professional LED flood lights are It is respected and loved by users in various industries, but due to the particularity of the material and technology of the floodlight, the current floodlight is mainly suitable for the following three application scenarios:
What are the main application scenarios for LED floodlights?
one. Various types of building lighting
Because LED floodlights have a long service life and can be intelligently controlled, they can be used to brighten the appearance of some large buildings. Some users also use this kind of colorful and artistic in order to increase the effect of scenic spots at night. Daylighting lights. In addition, for some public landmark buildings, LED floodlights can also be used for lighting design to better highlight the characteristics of the city.
Two. Indoor lighting
LED floodlights are also very suitable for the lighting and decoration of indoor spaces. Because the color of the floodlights is very soft, many users use them in the interior lighting design. By using LED floodlights, the entire space can be seen. It is more interesting and connotative, and some users who consider the cost of the lamp, in order to effectively reduce the replacement rate of the lamp, will also use a longer life daylighting lamp to replace ordinary lighting facilities.
Three. Commercial lighting
LED flood light has a variety of dynamic lighting effects, so it is widely used in various stages, performances and entertainment venues. Because LED floodlights can control color changes and light brightness through digital intelligence, both static lighting effects and dynamic lighting effects can be perfectly presented, which can provide excellent lighting effects for various commercial lights.
At present, the popular LED flood light is suitable for scenes. In addition to some large-scale buildings, public facilities, and home interior and commercial lighting, LED flood lights are easy to install and operate, and can also be applied to some large outdoor electronic screens. In the industry, this type of equipment and this type of projection lamp can better improve the screen brightness and color resolution. With the continuous improvement of the research and development technology of LED floodlights, the application places of LED floodlights will also be more extensive.
LED flood light classification:
one. Rotation and symmetry
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 light intensity curve of this kind of lamps is concentric circles. When this form of LED flood light is illuminated by a single lamp, the elliptical spot is obtained on the illuminated surface, and the illuminance is uneven; but when multiple lamps are illuminated, the spots are superimposed on each other, which can produce a very satisfactory lighting effect. . For example, hundreds of rotationally symmetrical projection lights are commonly used in stadiums, which are installed on high towers around the stadium to obtain high-illuminance and high-uniformity lighting effects.
Two, 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 axis of the cylindrical surface.
Three, a symmetrical plane row
The light intensity curve of the luminaire has only one symmetry plane. The luminaire adopts asymmetrical cylindrical reflector or symmetrical cylindrical reflector plus a grid that restricts light. The most typical is the light distribution of the sharp cut-off block retracted shape. This kind of light intensity distribution single lamp can obtain a more satisfactory illuminance distribution.
Fourth, asymmetrical shape
The iso-intensity curve of this type of luminaire does not have a plane of symmetry. It mainly uses 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.
LED flood light characteristics:
At present, the commonly used LED flood lights on 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 secondarily distribute the light emitted by the LED, which is two Sub-optical), and a few companies have selected 3W or higher power LEDs because of the good heat dissipation technology. It is suitable for the lighting of large-scale occasions and buildings.
What are the other things that need to be paid attention to in the flood light?
1. High-purity aluminum reflector, the most accurate beam and the best reflection effect.
2. Symmetrical narrow-angle, wide-angle and asymmetric light distribution systems.
3. It is easy to maintain the light bulb with the open type on the back.
4. The lamps are all attached with a scale plate to facilitate adjustment of the illumination angle.
The LED flood light is controlled by a built-in microchip. In small engineering applications, it can be used without a controller. It can achieve dynamic effects such as gradation, jump, color flashing, random flashing, and gradual alternation. It can also be controlled by DMX , To achieve effects such as chasing and scanning. At present, its main application places are probably these: single building, exterior wall lighting of historical buildings, building interior and exterior lighting, indoor local lighting, green landscape lighting, billboard lighting, medical culture Special facilities lighting, bars and dance halls and other entertainment venues atmosphere lighting and so on.
