IoT health lighting example
The LED lighting industry now respects naturalistic design. For example, many indoor LED lighting products simulate sunlight, simulate blue sky, and simulate the color and light seen in nature.
Office scene
Pure white LED light will make the office space have no sense of hierarchy and become boring and monotonous. Research surveys show that the performance of employees in office spaces using colored lighting is higher than that of employees working in pure white light spaces.
Light color, warm and cold, and intensity. When employees first come to work in the morning, they use the brightest and coldest light to stimulate them, so that they can start working mentally.
When it's about to eat at noon, slowly dim the light to make the color of the light warmer. Such warm white led lamps will stimulate employees to feel tired and remind them that it is time for lunch and rest.
It’s easy to get sleepy in the afternoon, because I have to face half-day work. At this time, the lights are re-adjusted to high brightness and high color temperature, so that the employees can return to their normal working conditions in good spirits.
In the evening, in order not to affect the body's normal secretion of melatonin, so that the employees can get a good night's sleep, at this time the lights are gradually dimmed and the color is adjusted to warm light.
Hospital scene
Such a system can also be used in hospitals to use different lighting at different time periods. Through the realization of healthy lighting, it can promote the healing of patients. Many patients have no way to contact the natural environment during the hospitalization process, and in many cases they will not be able to distinguish whether it is day or night. Through such a system, the patient's biological clock can be returned to a healthy state normally.
Using such a system can allow patients to fall asleep longer and have shorter repetition times at night, and can also reduce the patient's depression index, thereby speeding up the patient's recovery.
UV-C upper air disinfection
UV-C ultraviolet radiation can damage the DNA and RNA of bacteria, viruses, and spores, making them non-hazardous. UV-C technology has been used safely and efficiently in hospitals and government buildings for more than 40 years, and there is currently no known UV-C microbial resistance. Most UV-C solutions use traditional lighting, and now LEDs are used to improve efficiency. Lower wavelength UV-C (222nm) is being explored as a less harmful alternative.
UV-C upper air disinfection products divide the room into three spaces: upper UV-C air disinfection space (above 2.3m), safety space with exposure limit (eye level 1.7m-2.3m), personnel activity space (activity Type, sitting or standing, activity time is determined).
UV-C ultraviolet rays can continuously and effectively disinfect a large amount of upper air in the irradiated area during daily activities. The shading fan blades and unique optical design outside the lamps can effectively control the UV-C ultraviolet radiation. Ensure the safety of use.
Other applications
The luminous ceilings used in Apple's flagship store and Renault Auto Pavilion can simulate different outdoor weather and different climate environments through different color and light combinations.
There are other applications, such as indoor navigation through light coding technology, which can be used in garages and shopping malls. Now the very hot LiFi visible light communication technology can achieve signal transmission on airplanes and motor cars, which is very safe. 5G smart light pole, a combination of cameras, display screens, air quality, environmental quality and other sensors.
