What Is a Runway Guard Light (RGL)?
Runway guard light (RGL) is a yellow, unidirectional and flashing lighting unit. It is used to warn pilots and vehicle drivers that they are about to enter an active runway. Runway guard lights are installed at taxiway and runway intersections.
Selux Develops Special Insect-Friendly Street Light
German lighting giant Selux has developed a new street light to help protect insects’ habitats. Insect-friendly special lighting design ensures that light emissions from street light only reach roads and pavements. In doing so, it continues to comply with lighting standards for road safety.
How Do Fireflies Glow?
The glow of a firefly is a chemical reaction caused by a compound called luciferin (“light-bringer” in Latin) in the abdomen. Air entering the firefly’s abdomen combines with the luciferin and causes a chemical reaction that emits a light. The uric acid crystals in the cells that make the light carry the light away from the abdomen.
What Is Amber Light Color?
Amber is used to describe a particular hue that lies between yellow and orange. The wavelength of amber light is in the range of 600-615 nm. The color of light starts to turn yellow when the wavelength decreases below 600 nm and orange when it rises above 615 nm.
Traffic Lights Redesigned for the 21st Century
Outdated traffic lights and faulty signal lamps can send false signals to drivers and pedestrians, causing traffic accidents and injuries. On the other hand, the classic design of the traffic light can make it difficult for those who are colorblind to distinguish between red and green. Art. Lebedev Studio redesigned the traffic lights with a modern look and technological innovations suitable for the 21st century.
Increased Safety for Pedestrians: Smart Pedestrian Crossing
Did you know that approximately 1.35 million people die each year due to traffic accidents? More than half of those killed in traffic accidents are vulnerable road users, namely pedestrians, cyclists and motorcyclists. Estonian technology company Bercman has an innovative solution to mitigate these risks.
What Is Via?
In a multi-layer printed circuit board (PCB), the small holes that provide the electrical connection between the layers are called Via. Holes are drilled through the board on the different layers of the circuit board and made conductive by electroplating or by placing a copper cylinder in the hole.
What Is the Difference Between Off-Grid and On-Grid Solar Energy?
Off-grid solar systems require batteries to store energy, are not connected to the local grid and are self-sufficient. On-grid solar systems are connected to the electricity grid and therefore do not need batteries. This is the main difference between off-grid and on-grid solar power system.
What Is the Difference Between PWM and MPPT Charge Controllers?
Solar charge controllers control the energy coming from the solar panels, adjust the current and voltage, then send it to the batteries. A charge controller is needed in every solar energy system. Charge controllers are divided into two as PWM (Pulse Width Modulation) and MPPT (Maximum Power Point Tracking).
Do Chickens Need Light?
Light is an important factor influencing the development, welfare and egg production of poultry. Generally, in winter, egg production slows down because there is not enough daylight. During this season, chickens can be provided with artificial light to continue egg production.
