3. Terminology 3.1 Horizontal illumination: Illuminance on a horizontal plane 3.2 Vertical illumination: Illuminance on a vertical plane 3.3 Performance area: Bands, actors, etc. Areas used for public performances 3.4 Self-entertainment area: dance floor, karaoke Areas such as halls and KTV rooms for the public to perform entertainment such as singing and dancing. 3.5 Watching the rest area: the area where the public watches or rests on the field. 3.6 Channel: the area for people to walk
4. The dance hall in the dance hall is divided into four regional performance zones, self-entertainment zones, viewing rest zones and passages according to its functional requirements.
5. Illumination standard and its measurement and evaluation rules 5.1 Illumination standard lower limit: The lower limit of illumination standard in each area is shown in Table 1. The lower limit of the standard value of the illumination of the performance area is allowed to be smaller than the short time in accordance with the needs of artistic processing. Provisions.
Regional test point from the ground height (m) Test item illuminance standard value lower limit (lx) Performance area 1.5 Vertical illumination 100, ※ 150, ※ ※ Self-entertainment area 0.75 Horizontal illumination 20 viewing rest area 0.75 Horizontal illumination 5 Channel 0.25 horizontal illumination 10
Note: ※: The farthest audience is less than 8 meters from the center of the performance area.
※※: The distance from the farthest audience to the center of the performance area is more than 8 meters.
5.2 Measurement and evaluation rules 5.2.1 Measuring instruments: Measuring instruments should use illuminance meters with an accuracy of two or more.
5.2.2 Measurement method 5.2.2.1 Area of ​​the tested area 5.2.2.2 shall be carried out in accordance with GB5700-85 "Indoor Lighting Measurement Method".
6. Laser limit value and its measurement method: laser should not be directed to the human body, especially the eye, when directly irradiated or reflected and indirectly injected into the human body, the limit value is as follows: 6.1 wavelength limitation range: the wavelength must be 380nm-780nm between.
6.2 Maximum allowable irradiance -6 -2; maximum allowable irradiance is 1.4 × 10 Wcm.
6.3 The measurement method shall be implemented in accordance with GB10435-89 “Standard for Laser Radiation in the Workplaceâ€.
7. UV limit value and its measurement method 7.1 Wavelength limit range: The wavelength must be between 320nm and 380nm.
7.2 Maximum allowable exposure: -6 -2; maximum allowable exposure is 8.7 × 10 Wcm.
7.3 Measurement methods 7.3.1 Measuring instruments: UV illuminometer 7.3.2 Measurement method: According to GB5700-85 "Indoor Lighting Measurement Method".
8. Strobe limit value and its measurement method 8.1 Strobe frequency limit value: The strobe frequency is 8.2 stroboscopic lamps should not be used continuously for a long time.
8.3 Measurement method 8.3.1 Measuring instrument: The measuring instrument adopts the stopwatch 8.3.2 measuring method: each time measuring 30 seconds, the stroboscopic number is measured, a total of 5 times, and then the maximum value is taken. If multiple lights are used at the same time, the frequency is calculated cumulatively.
