23), National Fire Protection standard (such as UL1971) and North America fire protection criteria (such as Canadian standard ULC-S526-07), in detail
Describe test macro described in Fig. 2 is how to complete test job.
Each different standard defines the light coverage area that light crossing-signal should have in a manner of respectively unique.Example
Such as, Chinese Industrial Standards (CIS) GB26851-2011 concrete regulation：It is " clear outside 25m under the illuminance of the bias light of 100lux-500lux
It is clear visible ".It means that the practical smooth coverage area of light crossing-signal is at least 25m.But it is unpromising in the Chinese Industrial Standards (CIS)
The minimum illuminance of " high-visible " setting quantization.For another example, European standard EN54-23 concrete regulation producer produces light alarm
The light coverage area of the light crossing-signal of wall dress can be described when device with W-H-L.Light coverage area described in W-H-L is one
Space in a rectangular parallelepiped shape, wherein W indicates that wall dress, H indicate the coverage area in the cuboid short transverse, and L is indicated in width
With the coverage area on length direction.Similarly, in European standard, indicate that the light of top dress light crossing-signal covers model with C-H-R
It encloses.Light coverage area described in C-H-R is actually the space of a cylindrical shape, and wherein C indicates that top dress, H are indicated at this
Coverage area in the short transverse of cylindrical body, R indicate the diameter of cylindrical cross section.In addition, Unite States Standard and Canada's mark
Standard respectively defines light distribution of the light crossing-signal on the level angle of -90 degree to+90 degree.It can be seen that the U.S. and northern standard of beauty
The coverage area of the light crossing-signal of defined may be regarded as the space of a hemisphere shape.
In view of the above-mentioned difference of each standard room, the present inventor is pointed out by analysis：Light is alarmed under various criterion
The light coverage area of device can be regarded as a light radiation space body that light crossing-signal should have (for example, above-mentioned cylindrical body, length
Cube and hemisphere).The luminescent reference point of light crossing-signal is located at some position of the light radiation space body.For example, for EN54-
The die-filling formula in 23 top, luminescent reference point are located at the center on cylindrical body top surface.In this way, if in this light radiation space body
Body surface face at the light that measures meet the given target value of relevant criterion, then it represents that related light crossing-signal meets the standard.This hair
Bright inventor further provides with spherical coordinate system the test point on the body surface face for describing these light radiation space bodies.Fig. 2
In control device 240 can by adjust rotating around the first rotary shaft ZαWith the second rotary shaft ZβThe angle of rotation determines one
Test point, the body surface face for the light radiation space body that the light crossing-signal which should be located at a correlation standard should have
On.It is designed in this way, the light coverage area of the light crossing-signal of defined can be unified under various criterion, and simplify sample
