The International Electrotechnical Commission has classified film, television photography and theatre stage lighting as a specialized lighting technology field. For the quartz halogen bulbs and metal halide lamps, the models of the lamp caps, lamp holders and gauges have been internationally named.
The lamp holder and lamp holder models for film, television photography and stage lighting are composed of English letters and characteristic main parameter parameters that characterize their structural features. They generally consist of three parts: the first part represents the type of lamp holder and lamp holder; The two parts represent the size of the mating part of the lamp cap and the lamp holder; the third part represents the number of the lamp caps, the number of conductive contacts of the lamp holder or the number of pins. Their constituent factors are specified as follows:
1. Representation symbols for the types of lamp holders and lamp holders for film, television photography and stage lighting (1) Representative symbols for the types of lamp holders and lamp holders for film, television photography and stage lighting, expressed in the following English capital letters:
F--Single-pin base or socket G--Double-pin or multi-pin-type lamp cap or lamp holder P--Pre-focusing cap or lamp holder Gy--G behind the y indicates the two pins of the lamp end (hole ) the diameter is not equal, it is a big one school
(2) The lamp holders are of the same type and some of the same features, but the interchangeable lamp caps or lamp holders can be marked with x, y or z after the original model letter of the lamp cap or lamp holder, such as G9. The center distance of the double pins of the Type 5 and Gx9.5 bases is 9.53 mm, and the outer diameters of the pins are also the same, but they cannot be interchanged due to the difference in width and thickness of the base. (Note: If necessary, add the English letters such as xx, xxy, xz, yx, yy, yz, zx, zy, and zz to the original model word line.) (3) For the socket of the lamp socket or the socket The shape is indicated by the following lowercase English letters:
a--Cylindrical pin (for the lamp cap) or jack (for the lamp holder) c--Specially shaped pin (for the lamp cap) or jack (for the lamp holder) 2, film, TV photography lighting and theater stage lighting cap The size of the mating with the lamp holder is indicated by an Arabic numeral. For the pin or the lamp end is expressed as an approximation of the diameter, for the lamp holder, the approximate value of the jack diameter is used, for the pre-focusing cap sleeve outer diameter (sector and socket type) or the positioning plate outer diameter (positioning disc type) Said.
3, the number of lamp pin or the number of conductive contacts of the lamp holder The number of pins of the lamp cap or the number of the conductive contact hole of the lamp holder are indicated by lowercase English letters, as specified below:
S--1 only d--2 only (can be omitted without causing misunderstanding) t--3 only q--4 only p--5 only 4, the type and size of the pin-type lamp head are in international standards, The type and size of the pin-type base only indicate the style and fit size of the base structure that matches the lamp holder of the corresponding model, which affects its versatility and interchangeability. Instead of indicating the size of the pin-type lamp cap, all the lamp manufacturer must enforce it. Outside the specified shape and size range, the manufacturer can determine the type and size of other parts according to the user's needs.
