Preliminary Understanding of LED Floodlights
Characteristic:
Advanced LED light source technology, according to the characteristics of LED semiconductor lamps, intelligent circuit design and unique geometric appearance, LED floodlights can save up to 80%, and truly energy-saving. Lifespan up to 50,000 hours or more. It can be used in a variety of special environments, such as low temperature and high temperature conditions. It solves the problem of low power consumption and insufficient brightness in the field of semiconductor electric light sources and shows superior ultra-high brightness characteristics. Excellent air performance Optical performance is lighter and more perfect than 75W/400W/1000W metal halide lamps.
The LED flood lights commonly used in the market are basically 1W high-power LEDs (each LED element has a PMMA high-efficiency lens, and its main function is to perform secondary light distribution on the LED light, ie, double optical). In addition, few companies use 3W or higher power LEDs unless they have very good heat dissipation capabilities. Suitable for large lighting, buildings and other outdoor lighting. Then, what else needs attention?
1. High-purity aluminum reflector, the most accurate beam, the best reflection.
2. Symmetrical narrow angle, wide angle and asymmetric light distribution system.
3. Replace the bulb from behind the lamp body for easy maintenance.
4. The lamp uses the scale plate to adjust the irradiation angle. LED floodlights are controlled by a built-in microchip that can be implemented without a controller in a small engineering application. DMX can be used to achieve dynamic effects such as gradients, jumps, flicker, random flashes, and gradients, Chasing, scanning and other effects. Its main application places may be: monochromatic buildings, historical buildings exterior lighting, lighting, bars, dance halls and other entertainment venues, atmospheric lighting and other indoor lighting.
Advantage:
The LED floodlight lamp body is compact, easy to hide or install, not easy to damage, good light casting effect, good monochromaticity, soft light, low power, long life, and light time up to 50000 hours. It helps to protect the lighting objects and has a wide range of applications.
Precautions:
High-purity aluminum mirrors, the most accurate beam, optimal reflection, symmetrical narrow angle, wide-angle and asymmetrical light distribution systems, behind the open bulb, easy-to-maintain luminaires with graduated plates to adjust the angle of illumination.
Installation and use:
The spotlights can be individually installed or combined into multiple lamps and mounted on poles of 20 meters or more to form high pole lighting fixtures. With its beautiful appearance, centralized maintenance, and reduced polar and space, the device’s greatest advantage lies in its powerful lighting function. When light is projected from a height, the surrounding space has high brightness, large light coverage and a feeling similar to daylight, resulting in higher lighting quality and visual effects. In order to meet the minimum safety requirements for outdoor use, the spotlight housing protection should be IP × 3 (open type). In order to improve the durability of the lamps and reduce the maintenance workload, the development of a one-time high investment cost closed floodlight has received more and more attention. The lowest enclosure protection rating should be ≥ IP55.
In order to increase the overall light output ratio of the luminaire, the reflector tends to use a volumetric surface reflector, which helps to reduce the need for light blocking and multi-focal reflectors to meet special lighting requirements; surface treatment of reflective surfaces tends to be used New materials and new processes achieve over 96% reflectivity.
In order to reduce the weight of LED floodlights and reduce the consumption of metal materials, the lamp housing will gradually develop in the direction of high temperature resistant, high mechanical strength and weather resistant plastic housings.
