A lighting control system is an intelligent network based lighting control solution that incorporates communication between various system inputs and outputs related to lighting control with the use of one or more central computing devices. Lighting control systems are widely used on both indoor and outdoor lighting of commercial, industrial, and residential spaces. Lighting control systems serve to provide the right amount of light where and when it is needed.
Lighting control systems are employed to maximize the energy savings from the lighting system, satisfy building codes, or comply with green building and energy conservation programs. Lighting control systems are often referred to under the term Smart Lighting.
Shutter, Blind and Curtain control
Advanced control of curtains and blinds can also be used to naturally regulate temperature in the home, if lighting levels are high and the temperature is rising in rooms on one side of the house our systems can close the blinds a small amount to regulate the temperature – saving on the use of expensive air conditioning. The more intense the sunlight the more the blinds can close. The same lighting control system can also be used to protect fabric on soft furnishings, artwork and other items in rooms from the bleaching effect of direct sunlight.
A/C and Heating Control
An air conditioner is a major or home appliance, system, or mechanism designed to change the air temperature and humidity within an area (used for cooling and sometimes heating depending on the air properties at a given time). The cooling is typically done using a simple refrigeration cycle, but sometimes evaporation is used, commonly for comfort cooling in buildings and motor vehicles. In construction, a complete system of heating, ventilation and air conditioning is referred to as “HVAC”.
In the fields of physical security and information security, access control is the selective restriction of access to a place or other resource. The act of accessing may mean consuming, entering, or using. Permission to access a resource is called authorization.
Locks and login credentials are two analogous mechanisms of access control.
LED Light Fittings
LED HID replacement lamps are available in 30–400W for replacement of 50–1000W HID lamps. A typical upgrade is replacing a 400W metal halide lamp with a 17,000-lumen 150W or 21,000-lumen 200W LED lamp. Correlated color temperatures are available in 2000–5000K offering a spread of colors from very warm (similar to high-pressure sodium) to very cool (similar to metal halide). Color rendering index (CRI) is typically in the low 80s. The majority offer a 50,000-hour L70-based service life and carry a warranty from five to 10 years.
Monitoring and Visualization
This much-needed critical review of the main monitoring techniques conveys profound knowledge of their fundamentals, possibilities and limits, strengths and weaknesses when applied to membrane processes, clearly demonstrating which technique is most suitable for a given process. A practical approach is adopted throughout, providing case studies for the monitoring of selected membrane-based processes.
After an introductory section, the book goes on to look at optical and electronic microscopic techniques, followed by electrical, laser and acoustic techniques, and finishes off with process-oriented monitoring techniques.
Sound system is also used to refer to a free party sound system, also known as a rig. The equipment will be a van, loudspeakers, amplifiers, decks and cables but larger rigs might also have a fog machine, lighting, projectors and an electrical generator. A sound system collective is usually five or more people, with larger sound systems having more members. Equipment is owned by some and others are DJs, record producers or enthusiastic ravers that help out. They will be the people who organise free parties and teknivals and will be a group of friends with similar interests.
Standalone Motion and presence sensors PIR
A recessed lighting assembly is adapted to be integrated with a motion detector subassembly, photoelectric cell, and an electronic timer. The motion detector subassembly includes motion detector sensor(s), a focusing device and a decorative shield over focusing device. Motion detector subassembly is generally disposed inside the decorative trim. The required conditions for allowing electrical power to reach said electric lamp are the presence of line electric current, detection by motion detector subassembly of infrared radiation attributable to human and/or animal presence, and a lack of ambient light as measured by said photoelectric cell.
