For this Standard to be applied, the lighting needs of sports areas should be considered at the design and layout stage of the planning of such venues, in order that lighting equipment and supporting structures may be located so as to provide the required uniformity of illumination, to minimize glare and obstruction to participants and play respectively and to minimize the obtrusive effects of outdoor lighting.
For each type of sport there are preferred locations for the mounting of lighting equipment.These locations are related to the nature of the sport, the direction of play and other factors.Early consultation between the architect (venue designer) and the lighting designer is desirable to ensure provision is made for suitable locations and mountings for lighting equipment. A completely satisfactory installation is often difficult to achieve when limited by physical constraints, which can be avoided if lighting is considered at the design stage.
An LED driver is an electrical device which regulates the power to an LED or a string (or strings) of LEDs. An LED driver responds to the changing needs of the LED, or LED circuit, by providing a constant quantity of power to the LED as its electrical properties change with temperature. The driver can also either provide for fixed illumination, or enable the LED light source to dim, as required. They may be integral or external to the luminaire.
The ratio of the illuminance provided by a notional average luminaire in an installation, in an average condition of dirtiness (based on the environment and maintenance schedule) but with a new light source, to the initial illuminance provided by the same luminaire.
A device for controlling the luminous flux from a light source by reflection from suitably shaped surfaces. These may be either specular (e.g. mirrored glass or polished aluminium) or diffuse (e.g. vitreous enamel). In the former, the light is reflected in accordance with the laws of optical reflection. In the latter the light is diffused, largely without reference to any particular direction.AS 2560.1 pdf free download.
