While energy efficiency is the most common benefit, LEDs have other benefits besides energy efficiency. LEDs (LEDs) are the easiest to replace, with energy efficiency improvements of 6 to 7 times and energy consumption up to 80%. But in addition to energy saving, with the advancement of technology, the use of LED will bring greater benefits.
Lin Sheng explained that LED lighting offers a wider range of options for facility managers. Advances in control have also made the artificial light source operate much larger than before, creating different types of interactions that go far beyond the on/off switch. As an example, LEDs can now manually adjust the color temperature from cool white to warm white.
The effects of lighting on human health and behavior are also being studied, with particular attention to the inhibition of blue light emission by melatonin.
LED technology offers facility managers a new possibility that goes beyond the possibilities of traditional lighting.
1. LED tape and linear profiles. Using LED strips and linear profiles, printed circuit board (PCB) embedded LED chips provide greater flexibility in length and optical choice, which was not feasible in previous designs or can be achieved within a given budget .
For example, previous energy code management spaces and missions for bay lighting methods required the use of fluorescent strips that left significant socket shadows and were only available in a small standard length (2-, 3-, 4-, 5- and 8 feet). This greatly hampers their use without significant manipulation. LED strips or linear profiles now typically provide very small increments as short as 2 inches, which easily accommodates odd bay lengths and also reduces physical space requirements.
Linear LED profiles with optical lenses provide better control of the light distribution of wall grazing and wall cleaning. Because the LED source is very small, the optics can effectively control the beam angle while still maintaining a small lamp size. Using an optical lens, the distribution of the emitted beam and light can usually be controlled to be as tight as a 6-degree beam for "grazing light" onto textured and embossed vertical surfaces, such as stone and concrete walls, up to 50 to 75 feet. Asymmetrical optics distribute the illumination evenly across the vertical surface, making it ideal for "wall cleaning" applications on advertising surfaces, teaching surfaces or other wall surfaces that may require uniform peripheral brightness.
2. Intelligent lighting. As an inherent digital device, LEDs can be used with control and other systems to create unique solutions.
For example, a museum is exploring the use of Bluetooth LED spotlights. Although the project is still under development, track-mounted spotlights with motion sensors and lux sensors provide intelligent lighting solutions that help protect artwork. When the motion sensor is not occupied, the motion sensor can reduce the amount of light that the artwork is exposed in the gallery, while the lux sensor can set the maximum illumination limit that will be exposed in any one job. The onboard chip will provide useful feedback on module strength, power, LED temperature, PCB temperature and input voltage characteristics.
Lighting technology is a science that is constantly evolving. These technologies enable energy savings and integration with building management systems, allowing one sensor to control lighting and mechanical systems.
The other two benefits illustrate the value of LEDs.
3. LED light board. LED light board is a very thin panel (reminiscent of acrylic panels) with peripheral embedded LED modules. The sheet has a linear cut groove matrix to refract light distribution from the perimeter to the panel surface. A uniform and uniform backlighting effect can be achieved by using various diffusers, such as milky white polycarbonate.
This product has many uses and advantages. Applications range from retail displays and the like where the heat of the LED source can be dissipated at the edges and further reduced by the use of metal bezels at the edge of the shelf. This allows a heat sensitive product such as a fragrance to be placed on the illuminated surface for display purposes without degradation of the product.
Other applications include providing a backlight that is recessed in a wall or ceiling surface, where space is limited to the use of conventional light boxes. The variable colors of such recently added products further expand their range of use.
4. Color. LEDs also provide better saturation and color rendering, and many exterior facades are now available in color. The use of digital multiplexing previously used to control stage lighting and effects is one of the most common control protocols for adjusting variable color and pixel manipulation in internal and external commercial lighting solutions.
The use of color can provide dramatic visual effects; however, the application of color requires careful consideration to ensure proper use, and coordinated external lighting solutions tend to work more successfully.
