LED Stage Lighting Glossary

With the rapid development of science and technology, modern science and technology for the development of television technology has played a role in fueling. LED stage lights as a product of modern technology in film and television lighting techniques, particularly the use of more extensive usage is also growing, much to replace conventional general lighting trends in the production process in a number of variety shows on TV.LED Stage Lighting Glossary include brightness.Illumination .flux .color temperature.the channel.

 1.A brightness

Brightness refers to the area around a point on the surface of the micro-units, the luminous intensity emitted in a given direction divided by the unit projected area to the same direction, the unit is: cd / c㎡. In lighting systems are not normally encountered in the brightness of the concept.

2, Illumination

Illuminance refers to the density of a surface of the light flux, which is incident on the luminous flux per unit area, the unit is LX. The definition and measurement of the illuminance is more complex, as the average illuminance cylindrical, spherical equivalent illumination, illuminance of the scalar, and the measurement conditions are different calculation methods. In the construction and decoration projects often encounter, occasionally lighting system is also related to the concept of illumination.

3, flux

Flux refers to the unit of time away from the light source to the surrounding space radiation can cause visual reaction energy, ie the energy of visible light. It describes the value of the effective radiation source, the unit is 1m (lumens). The same power flux of the lamp may be completely different, this is different because of their light efficiency's sake. For example: ordinary light bulbs only 10 1m / W, while the metal halide can reach 80 1m / watt.

4, color temperature

Hue refers to the color temperature of the light emitted by the light source color temperature of a blackbody radiation at the same time, the color temperature of the blackbody temperature of the light source referred to generally in units of Kelvin k. For example, 3200k and 5600k and so on. High color temperature, color light cool: low color temperature, color light warm: When moderate color temperature, light and close to white. Under normal natural sunlight, the color temperature of the light fixtures generally have higher color temperature manually. Typically, the color temperature of the sun is about 5600k, and studio lighting color temperature and performances are 3200k (hot source). But the recent cold light rise of television studio lighting, is change the traditional light sources. Cold light of high color temperature, low energy consumption, heat a small, indoor and outdoor camera during phase, color temperature conversion is simple, the screen naturally, of course cold light dimming sets performance requirements should be higher.

5, the channel

In modern optical control, the concept of generating a new channel. It refers to a collection of a control circuit in the luminaire. Specifically is this: has the function of a lamp needs to be controlled separately (eg: focus, flash, color, etc.), and occupied Dimmer output circuit is collectively channel. For example: a computer lights function aperture, color, strobe, dimming, lens horizontal movement, vertical movement, so they occupy channel is 6. It can be seen, the concept of channels or traditional lighting control circuit evolved, but modern lighting is the multiple channels together on one unified control device. Of course, more advanced lighting, more complex, more action, the number of channels occupied more likely, on the lighting console requirements are also higher. For example: A 108 optical path, dimming station has a digital output, which in order to control the computer with a 12-channel light, so it can control up to nine such lamps, is how to control signals and address allocation problems a.
