3.10 Name of lamp position

     In the frame stage, the following names are commonly used for the location of the lamp installation.

3.10.1 Frontal light (also called surface light)

      The light position located outside the stage entrance and projecting from the top to the stage is called the first front light by the stage entrance, in order of two front lights and three front lights...

3.10.2 Outside light of the mouth (also known as slap, outside light)

      A light position located on the side wall of the auditorium and projecting light from both sides of the stage entrance to the stage. According to the provisions of 3.8, the left and right sides are divided. When there are more than two channels of outside light, they are divided into one, two, and three channels in the order specified in 3.10.1.

3.10.3 Inner side light (also called column light, false side light)

       The light positions located on both sides inside the stage entrance, near the stage frame, are generally set on the side panels of the pillar lamp holder or fake stage entrance, and are divided into left and right according to the provisions of 3.8.

3.10.4 Side light (also called inside light, flyover light)

       The light positions on both sides of the stage are divided into left and right according to the provisions of 3.8. When there are multiple side lights on the same side, they are called one side light, two side lights, and three side lights in order from bottom to top.

     Apply the relevant part of JGJ57 noun explanation (see Appendix C).

4 Symbol

  When drawing diagrams, the following prescribed symbols shall be used.

4.1 Symbols of commonly used lamps. (See Figure 2)

4.2 Symbols for accessories of commonly used lamps and lanterns. (See Figure 3)

5 Technical drawing

5.1 Drawing format and format The relevant provisions of GB4457.1 shall apply to the drawing format and format, see Appendix A for details. The title bar is located in the lower right corner of the picture frame, and its dimensions and contents are drawn as shown in Figure 4.

5.2 Form and application of graph

5.2.1 The relevant regulations of GB4457.4 shall apply to the name, type, code and width of various diagrams. For general application on the diagram, see Table 1.

Figure 4

5.3 Font

    The relevant regulations in GB4457 shall apply. (See Annex B)

5.4 Light map

    The light position diagrams are all expressed in the form of an approximate plan, and no elevation is required without special needs.

    The light map should be able to represent the following:

    a. The location and height of the lamp installation.

    b. The type, model, voltage, power and additional parts of the lamp.

    c. The number of the luminaire.

5.4.1 Representation of lamp position

5.4.1.1 Baseline

    The central axis, the platform line, the large curtain line, the curtain line and the installation position of the scene in the light position map should be drawn and dimensioned in proportion, the unit is meter, accurate to two decimal places. (See Figure 7)

5.4.1.2 Representation of plane position

    The plane position of the lamp is subject to the position of the lamp symbol. The size of the symbol has nothing to do with the actual ratio of the lamp, but it should be proportional to the proportion of the picture frame. The size of the same symbol in the same picture frame should be consistent.

5.4.1.3. Representation of lamp height

    Since the three-dimensional lamp position is displayed on the plan view, the phenomenon that the upper and lower lamp positions overlap on the drawing position may occur. Therefore, the following expression rules are specified. (See Figure 7)

    a. The light positions on the left and right sides of the stage are based on the central axis, the lower part is near the central axis, and the upper part is away from the central axis. The position of the lights inside and outside the stage entrance is based on the table entrance line, the lower part is close to the table entrance line, and the upper part is away from the table entrance line.

     b. The common three-dimensional light positions of the stage (such as the outside light of the stage entrance and the inside light of the stage entrance) are generally fixed in height, and can not be marked in the picture. The lamp positions that are easily confused with the plane lamp positions must be marked with height. Use the symbol in Figure 5 to indicate the plane position of the upper lamp position, and use the symbol in Figure 6 to indicate the height. When the arrow points to a single lamp, it indicates the height of the lower part of the lamp. When the arrow points to the contour line, it indicates the group of lamps. Height (based on the lower part of the lowest lamp). The unit is meter, accurate to two decimal places. (See lights 81-84 in Figure 8)

Figure 7

Explanation

1. The luminaire installed on the stage, the mark is 0.00m.

2. Compared with 1, the drawing position is far from the platform, and the plane position is the same as 1, indicating that it is on the upper part of 1, and the height is 7.50m

3. Side light, installed on the flyover, because the flyover height is fixed, you can not mark, and the lamps hanging under the flyover must be marked with height, the drawing position is closer to the central axis.

4. The light on the inside of the platform, the detailed drawing method is to mark the height of each layer.

5. The light on the outside of the platform is a fixed building, and the specific height may not be marked.

5.4.2 Marking of the performance and model of the luminaire If the symbol cannot fully express the performance of the luminaire, it should be marked. The position of the mark is below the symbol. If the position is not allowed, it can be led out with a lead wire and then marked. (See lights 75-80 in Figure 8)

5.4.2.1 Marking of voltage and power

    The unit of voltage is volts, no need to mark when using 220V voltage, if other voltages are used, they should be marked and written on the lower left of the symbol. (See Figure 9a)

The unit of power is KW. It is not necessary to write it when labeling, just mark the value, and write it at the lower right of the symbol. (See Figure 9a)

5.4.2.2 If there is a clear requirement for the type of luminaire, it can be marked below the symbol, and the voltage and power labels are omitted. (See Figure 9b)

5.4.2.3 If there are many lamps of the same type, only one lamp can be marked, and the others should be marked with "same X". (× represents the number or direction example see No. 61-68 in Figure 8)

When it is difficult to mark on the picture frame, a separate table may be set up as an attachment to the picture.

5.4.3 Numbering and marking of lamps

The number is the basis for the circuit and operation of the lamp connection, so it must be marked

5.4.3.1 The number of lamps should be based on the line number.

    The line number can be determined in the following two ways:

    a. All the lines controlled by the dimmer are numbered in sequence, and the direct lines that are not controlled by the dimmer are separately numbered, but the word "straight" must be marked in front, such as "straight-5", that is, the number 5 direct line .

    b. According to the number of the lamp position, indicate the abbreviation of the lamp position before the number. For example, the fifth line of front light can be edited as "face-5". When there are multiple lamps on the same line, the line number should be marked first, and then the lamp number of the same line. If there are three lamps on line 5, it should be marked as: "5-1, 5-2, 5- 3".

5.4.3.2 The number is marked as follows:

    It is marked below the symbol of the luminaire. If it is confused with the voltage and power labels, they can be separated by a thick solid line. (See Figures 9a, 9b)

5.5 Light pattern

    The light layout is generally expressed in an approximate plan view.

The diagram should be able to represent the following:

    a. Projection direction of the light beam

    b. Projection range of light beam

    c. Color of light beam

    The lighting map can be used together with the lamp bit map, or it can be drawn together with the lamp bit map. In the case of the lamp bit map, the lighting map can only draw the lamps needed in this scene, and generally no longer plot the performance of the lamps. , But the number must be marked. (See Figure 10)

5.5.1 Sagittal representation of the optical axis

      An arrow indicates the projection direction of the optical axis in front of the lamp symbol. (See lights 4-7 in Figure 10)

5.5.2 Representation of projection position and range

      The following three methods can be adopted as needed:

      a. Use text to explain near the lamp position. (See light 49 in Figure 10)

      b. Extend the sagittal symbol of the optical axis to the position to be projected with a thin solid line, and draw two arrows, positive and negative, between which is the range of light projection on the stage plane. (See lights 11 and 22 in Figure 10)

      c. Frame the projection area with a dotted line. The dotted line is called the projection range line, and the number and description are marked within the range. (For example, see the lamps 31-36 in Example 10)

5.5.3 Color representation

      The following methods can be used to express the color of lamps:

      a. Use a colored pen to draw the sagittal symbol of the optical axis and the projection range line, where the black line represents white light.

      b. It is marked with the number of the color film manufacturer. When marking a single lamp, it can be marked in the lamp symbol. If the symbol is too small, it can be marked near the lamp symbol, but the "#" character number should be added, and it can also be marked. Within the line of light projection or in the text description
