LED floodlights can perform better in decoration and landscape lighting through dimming, and show the decorative characteristics. LED flood light has a larger dimming angle than traditional lamps, so it is more flexible to use. The LED flood light adopts an integrated heat dissipation structure design. Compared with the general heat dissipation structure design, its heat dissipation area is increased by 80%, which ensures the luminous efficiency and service life of the LED flood light.
The first method is to realize dimming by adjusting the driving current of the LED flood light, because the brightness of the LED chip and the LED driving current have a fixed ratio.
The second type of dimming is usually called analog dimming mode or linear dimming. The advantage of this kind of dimming is: when the driving current increases or decreases linearly, the LED chip will be relatively reduced, and the change in the driving current will have a certain impact on the color temperature of the LED chip.
The third is to control the drive current to be square. The output power is changed by adjusting the pulse width. When the frequency conversion speed is generally 200Hz to 10kHz, people's glasses can no longer find the process of light change. Another advantage is that the heat dissipation is better. The disadvantage is that the overshoot of the driving current has a certain impact on the life of the LED chip.
We use LED floodlights to determine the number of lamps according to the illuminance calculation of the selected light source, lamps, installation location and other conditions. The exterior decorative lighting of the building is expressed by the projection of LED floodlights. In the design of LED floodlights , To perfectly express the characteristics of the building.
According to the needs, the light control of the LED project-light lamp should use a lens smaller than 6°, so that the beam is narrow, and the scattered light is gathered together, thus forming the concept of light control. LED floodlights are mainly used for decorative lighting and commercial space lighting. The decorative components are heavier. Because heat dissipation is generally considered, there are still some differences between their appearance and traditional LED floodlights. .
That requires narrow-angle light control, which can reduce light pollution without reducing the light, because it controls the light and can concentrate the light beams. No glare will not affect the lives of residents at all.
Narrow-angle light control products also have the characteristics of green, energy saving and environmental protection, which can gather the surrounding overflow and astigmatism, so that the projected area is not only bright but also has a longer range. This is the energy-saving performance of narrow-angle light control products than the general angle. The reason the product is good.
LED floodlights are also called spotlights. Usually it can aim at any direction, mainly used for building outlines, stadiums, overpasses, monuments, parks and flower beds. It is widely used outdoors. The beam angle of the LED floodlight is wide or narrow, and the range of variation is between 0°～180° and can be adjusted.
The LED flood light can be installed and used alone, or multiple lamps can be combined and installed on a light pole above 20m to form a high-pole lighting device. In addition to beautiful appearance, centralized maintenance, reduction of lamp poles and floor space, the greater advantage of this device lies in its powerful lighting function. When the light is projected from a high place, the spatial brightness of the environment is high, and the light coverage is large, giving people a feeling similar to daylight, so it has high lighting quality and visual effects.
The LED flood light adopts the integrated technology of LED electric light source. According to the characteristics of LED semiconductor light emission, it generates less heat and consumes less energy. The LED flood light can save more than 80% of electricity. Long service life, reaching more than 50,000 hours, can work normally under various harsh environmental conditions without being affected.
The LED flood light is controlled by a built-in microchip and 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 achieve chasing, scanning and other effects through DMX control.
The quality characteristics of LED flood light:
1. The use of internal and external anti-seismic structure design effectively solves various troublesome problems caused by strong vibration.
2. Using high-efficiency gas discharge lamp as the light source, the bulb has a long service life of more than 10,000 hours.
3. Using light alloy materials and high-tech spraying technology, the shell will never rust or corrode.
4. New technology such as piping is adopted to ensure good integrity of the shell, reliable sealing, waterproof and dustproof.
5. It has good electromagnetic compatibility and will not cause electromagnetic interference to the surrounding environment.
6. The overall heat dissipation of the lamp is good, which can reduce the probability of failure.
Compared with other lighting fixtures, the LED project-light lamp can be used without a controller, and the LED project-light lamp housing can also achieve a variety of special illumination effects during use. Therefore, the lighting effect irradiated by the LED floodlight shell is good, the color of the light is bright and the light is not dazzling, on the contrary, it is very soft, not only suitable for outdoor use, but also suitable for home lighting.
LED floodlights have been widely used in various places and fields. From the original indoor to the outdoor, from the original local lighting to the current overall lighting, it is the level of improvement and development. With the increasing progress of the times, Nowadays, LED floodlights have been invested in various fields of lighting projects. In the next few years, LED floodlights will develop into an indispensable part of the lighting projects.
