Chinese fire protection standard, such as GB26851-2011, define at distance light crossing-signal 25 meters of, under the bias light of 100 ~ 200lux, alerting light should be high-visible.But, there is no the quantitative values specifying " high-visible " in Chinese Industrial Standards (CIS) GB26851-2011.Existing means of testing adopts manually to test.Therefore, in the present embodiment, utility model people is by standard identical with EN54-23 for the high-visible employing that specifies in the GB26851-2011 of Chinese Industrial Standards (CIS), and namely illuminance is for being more than or equal to reference light illumination, such as 0.4lux.Certainly, according to actual needs, also the high-visible of GB26851-2011 other substandard reference light illumination can be defined as, also an applicable brightness value can be determined, as this reference light illumination according to actual conditions.
As known in the art, the power of bias light can affect the effect of alerting light.Such as, under identical alarming effect condition, bias light is more weak, and the illumination of alerting light can be lower; Bias light is stronger, and the illumination of alerting light needs corresponding increase.The conversion factor of different background optical condition light coverage is clearly given in European standard EN54-23.Conversion factor under the bias light of the varying strength of table 1 required by EN54-23 standard.
Table 1
As previously mentioned, each light crossing-signal product can identify nominal range, such as a W-2.4-3 when dispatching from the factory.W represents that wall fills.2.4 represent light crossing-signal setting height(from bottom), unit rice.3 represent coverage, unit rice.Under different background light, the actual coverage of the light crossing-signal of same nominal by corresponding different, and can utilize above-mentioned conversion factor to calculate, that is, actual service range=conversion factor × nominal range.The minimum actual service range come required by regulation China GB26851-2011 standard according to EN54-23 standard is 25m, and so such as under the bias light of 100-200lux, nominal range should be 25/4.4, is namely about 5.7m.Therefore, such as, under the bias light of 100-200lux, the illuminance of light crossing-signal under nominal range 5.7 meters need be at least 0.4lux × (5.7m)
2, namely light intensity is at least 13cd.Table 2 has exemplified out corresponding nominal range and the light intensity of different background light in GB26851-2011.
As described in formula (7), light intensity, between illumination and measuring distance, meet the relation of formula (7).Like this, based on measuring distance d during test, formula (7) can be utilized and calculate the illumination desired value under different background light with reference to table 2.
