CIE Foreword
The standards developed by CIE include brief documents of relevant data on lamp specifications and signal specifications. Considering the need to achieve international and domestic consensus, it is necessary to make such provisions. CIE standards provide internationally agreed data that can be applied to the worldwide standard system without major changes.
CIE summarized the recommended standards for light signals published between 1987 and 1993, and on this basis, this standard was completed.
CIE has approved this standard to replace the recommended standard for light signal colors published by CIE in 1975. Introduction
GB/9417-23
National and international standards for visual signal systems usually specify the requirements for light signal colors to ensure that people can correctly identify these colors. The recommended standards previously published by CIE provide effective guidance on how to choose these colors and are used in many different standards.
CIE was first adopted in 1959 The standard was based on experiments conducted in the 1930s and 1940s and the technical experience of the experts in the IF committee responsible for developing this standard. It also took into account the actual conditions and relevant standards of the time, as well as the practical limitations of colored signal equipment and the need to produce sufficiently strong signals. After that, new experiments and the actual application of the standard in 1959 led to the publication of its revised version in 1975. This is IF publication 2.219754 Light Signal In 1987, CIE published another revised version, CIE Part 4 (Traffic Lighting and Signaling), based on the need for further practice, requirements and changes in signal technology. The committee conducted a detailed analysis of experiments on the recognition of signal light colors and solicited opinions from experts in the field of signaling in various countries. The committee presented the results of the analysis in CIE Technical Report 107, Commentary on the Standards for Light Signal Colors Published by CIE, published in 1994. This report further describes the relevant experiments, the existing standards for color recognition, and is accompanied by a detailed reference list. The committee's analysis results were adopted by CIE Part 1 and used to guide the formulation of this standard. 1 Scope
Light signal color
This standard specifies the color range and test method of light signal (including flashing signal) color. GA/T 8417—2003
This standard applies to signal lights used in marine, inland waterway, road, aviation and railway transportation systems, including signal lights used on ships, cars, airplanes and trains.
This standard applies to signal lights and monitors on the control and monitoring dials of industrial control and monitoring units. This standard does not apply to the headlights and fog lights of automobiles, nor to the light with very low color temperature used in marine signal lights: 2 Normative references
The following documents become the references of this standard through reference in this standard. For all the reference documents, all subsequent rectification orders (excluding the internal errors) or revisions are not applicable to the reference documents. However, the parties to the standard agreement are encouraged to discuss whether to use the latest versions of these documents. For any referenced document that is not out of date, its latest version shall apply to this standard. GB/T5697 Human ergonomic lighting terminology

T—the transmittance per unit distance in the air.
4. Requirements
4.1 Light signal colors
GR/T8417—2003
Light signals shall be red, yellow, white, green and blue. No other colors shall be used. 1: Red is not suitable for light signals because the atmosphere selectively absorbs purple-red sub-color components. Therefore, red and purple are also prohibited. 2: Purple is not suitable for light signals because it is close to blue in color. It should not be used as a light signal because of its compatibility with blue and color. When the color is not as bright as blue, it can only be used as a light signal. 4.2 Color area range The chromaticity standard of the light signal color (second, it should be based on the chromaticity zone determined by the data in Table 1 and the spectral locus and the purple-red boundary. Note 1: The chromaticity zone boundary, the coordinates of the intersection point of the spectral locus and the forbidden red line are shown in Figure 2, and the effective color zone is shown in Figure 5. The coordinates of the light signal chromaticity boundary from 1 to 5 are shown in Table 1. Red signal color. ||Yellow border

The color of the light you trust will be reported in the entire process of the peak change by 1KL (for Class A) [for Class B) due to W.2.6. The green light signal color package also includes 4.6. 1 Class A
In addition to the provisions in 4.6.2, the green signal color must be reduced in the domestic area. 4.6.2 Class B
When observing users with color vision abnormalities, the color of the color-deficient light signal can be located in the color quality area MN (within the specification. GB/T8417-2003
Note 1, for users with primary color standard wide function years MVM, the quality edge color light energy will be different from the color of the package or color syndrome, because when the color of this area is removed,
Note 2; users with color vision abnormalities are prone to color slip and white. They can use Di to come over the river to purify Y and connect to [K's self-color to generate power, blood scene that is 4.7 Blue light signal color
4.7.14 Class
Except for the cases specified in 4.7.2, the blue light signal color must be within the color area QRST range: 4.7.2 Class B
When it is not required to accurately identify the blue light signal, the blue light signal color can be detected within the color area QRST range: Note: The monitoring package does not follow the visual signal because: Relatively speaking, the color monitoring material is not flammable!
When the angle is medium or low, the general audience will adjust the color and the confidence package to selectively radiate.
Net 2: If the color monitoring signal is lower, it will not be more common. The average illumination of the wearer is lower than 1x. The recognition effect will be better.
5 Test method Tao
Use a light harmonic meter to calculate the light distribution of the signal lamp, and use the day (L/H9/7 to calculate the IE193-package coordinates (worker), such as If the reliability of the first method is confirmed by the spectrum radiation method, this method can also be used: the light used for the test signal should be installed with the actual lamp pool specified in the specification. The operating voltage of the signal light should be specified. If the power supply voltage or frequency is different from the environmental conditions, the power output of the signal light will also change. In addition to the test under the specified operating voltage conditions, the test should also be carried out under the highest and lowest operating voltage conditions: under each voltage condition, the color of the light should meet the requirements of this standard.
