The application of C-BUS control system in the lighting of Xiantao Stadium

I. Project Overview

Xiantao Stadium is a new venue built. The main hall is a comprehensive official competition venue with a grandstand that can accommodate more than 4,500 spectators. The roof of the venue is 70 x 70 meters; the maximum competition area is 45 meters long and 30 meters wide: when the activity stands are extended, the competition area is 35 meters long and 20 meters wide.

Hubei Xiantao is the “hometown of Chinese gymnastics”, where national gymnastics competitions will be held; basketball, volleyball, indoor track and field, indoor football, handball, badminton, table tennis, tennis, boxing, martial arts, judo, weightlifting will also be held. Wait for non-relay games. In addition to the competition, this complex can also be used for a variety of purposes.

Second, the illumination standard

According to the requirements of national standards and bidding documents, the design requirements for venue illumination standards are as follows:

(1) Main venue sports venue

Horizontal illumination (ground floor) 1500 Lux

Gymnastics vertical illumination (main camera direction): 1000 Lux

Vertical basketball illumination (main camera direction): 700 Lux

Horizontal illumination uniformity: U1=Emin/Emax>0.5


Vertical illumination uniformity: U1=Emin/Emax>0.3


Light source color temperature: 5000K>Tk>3000K

Color rendering index: Ra>65

(4) Accident emergency lighting

In order to ensure that the mains stadium sports venue does not interrupt the game and television broadcast, emergency lighting is set up at the main stadium sports venue. The emergency lighting power supply for accidents is supplied by EPS backup power supply or standby generator set. The switching time between mains and accident power supply is no more than 30 seconds. When the mains power fails, there will be several iodine-tungsten lamps powered by the generators at the main venue sports venue to ensure a certain illumination. When the generator is powered, the illumination of the main stadium sports venue is >100Lux, and the illumination of the auditorium is >100Lux.

Third, the choice of lighting methods

There are three common ways to use the stadium lighting:

Evenly distributed light on the top;

Both sides of the lamp with light projection lighting;

The combination of uniform lighting and light-emitting illumination.

When the venue is large, the projection distance is long, and the light strip method is advantageous, and the vertical illumination of the light strip projection mode is high. The lighting mode of the design is four light strips, and the arrangement position of the horse track is shown in the drawing.

At the same time as the lighting venue, we installed 400W floodlights on the road to illuminate the auditorium and also to illuminate the white ceiling. This has several effects:

1. The illuminance of the audience is strengthened, which makes the broadcast effect better and the audience's vision is good;

2, the white ceiling is illuminated, eliminating the "black hole effect" of the ceiling, reducing the glare of the audience and athletes;

3. The illuminated ceiling plays the role of “flooding illumination”, and people can see the lighting effects in the venue from a distance.

Fourth, the choice of lamps and light sources

Six, glare calculation

It is required that the site lighting can not produce disappointing glare for athletes, staff and audience. The glare index is determined according to the GR value recommended by CIE. Generally, the GR value below 50 is acceptable. The calculation formula is:


Lvi - the brightness of the light curtain produced by the luminaire

Lve - brightness of the light curtain produced by the environment

Glare calculation for each lighting mode of Xiantao Stadium

Evaluation of GR value of coordinate observer glare index of model observer

X(m) Y(m) Z(m)

In the whole game, the front stand of the audience is 00 -25-10 51.5 28.7127.50.

Basketball game front stand audience inside the stadium 00 -25-10 51.5 23.4325.09 in line with the standard

Note: 1. The glare calculation selection direction is the maximum glare direction at this point, and the glare in other directions is lower than this calculated value;

The points of attention are the central locations of the museums;

80 sets of 1000W lamps in sports competitions, each of which is a circuit with a total of 40 circuits (W1-W40).

(2) Auditorium lighting

There are 36 sets of 400W lamps in the auditorium. Each 5-6 sets of lamps is a circuit with a total of 7 circuits (W41-W47).

(3) Emergency lighting halogen tungsten lamp, 2-3 sets of lamps are a circuit, a total of 6 circuits (W48-W53), powered by EPS intelligent emergency power supply.

3. The power supply and distribution system supplies power to both normal and emergency lighting for two separate dual power supply mutual investment boxes.

4. The library adopts C-Bus intelligent lighting management system of Qisheng Company to realize centralized, unified and intelligent management of lighting.

1) C-Bus is mainly used for the control of lighting systems. All of the system's unit devices (except the power supply) have built-in microprocessors and memory units connected by a pair of signal lines (UTP5) into a network.

2) C-BUS products can remember the parameters set for them. Each component has a unique address code in the network for identification. Each component can be programmed individually. The settings for the lighting system are distributed and stored in the various components.

3) Each unit is set with a unique unit address and its function is set by software, and each loop load is controlled by the output unit. The input unit is associated with the output component by the group address.
