Film and television and stage lighting lamp caps and holders together with model internationally uniform naming method.
The International Electrotechnical Commission, film, TV, photography lighting and theatre stage lighting is classified as a professional lighting technology. For quartz tungsten halogen lamps and metal halide lamps use lamp caps and holders together with gauges for model and implement the international uniform naming.
Film, TV, photography lighting and stage lighting of the lamp caps and holders together with model is the characterization of their structural characteristics of the English alphabet and characterization of the main size parameter numbers, generally including has three sections: the first represents lamp caps and holders together with gauges of the species; the second part represents lamp caps and holders together with the dimensions of the parts; the third part represents lamp caps and holders together with conductive contact number or PIN number. Their composition factors specific provisions are as follows:
1. characterization of film, television photography lighting and stage lighting lamp caps and holders together with description of the symbols
(1) characterization of film, television photography lighting and stage lighting lamp caps and holders together with the description of the symbols, use the following letters:
F — — single pin lamp caps or socket
G-double pin or only pin-head lamp-end or lamp holder
P-pre focused lamp or lamp holder
Gy-G y represents the light behind the end of the two pins (holes) diameter are not equal, is a big one.
(2) the same kind of lamp bases, some characteristics are the same, but are not interchangeable with lamp or lamp holder can spotlights or base original model letter followed by the x, y or z to distinguish the two, such as the G9.5-and dual-lamp Gx9.5 prong of the center distance is 9.53mm, pin diameter is the same, but the lamp holder width and thickness are different and are not interchangeable. (Note: if necessary, the original model of the line followed by the xx, xxy, xz, yx, yy, yz, zx zy zz, etc., and to represent the alphabet. ）
(3) for lamp holder pin or socket Jack shapes with the following lowercase letters said:
A-cylindrical pins (on head) or Jack (on chassis)
C — — the special shape of the plug (on head) or Jack (on chassis)
2, movie, television photography lighting and theater lighting lamp caps and holders together with the dimensions indicated in Arabic numerals. For pins or light side to diameter of approximation, lampholders, Jack diameter of approximation, pre focused prefocus used sleeve outside diameter (fan and bayonet) or locate disc diameter (positioning the disc).
Number 3, lamp Cap pins or bases of conductive contact number
Lamp caps the number of pins or base number of conductive contact aperture with a lowercase letter that specifically States as follows:
S-1 only
D-2 only (without misunderstanding can be omitted)
T-3 only
Q-4 only
P-5 only
4-pin type lamp types and dimensions of
In international standards, pin type lamp types and dimensions of only represents the corresponding type of base line, affecting its versatility and interchangeability of the caps structure style and size, not the size of that pin-lamp, lamp Cap production enterprises all must enforce. The shape and size, production enterprises according to user needs, and determine other parts of the type and size.
