Abstract
Film set lighting requirements can be met with a relatively small number of lamp head modules which are assembled to any of several different reflectors to make up combinations of lighting fixtures as the need arises. The lamp head module has integral ultraviolet protection provided by a close fitting transparent lamp cover so that HMI lamps may be safely used without other UV protection on the interchangeable reflectors. An HMI lamp igniter is provided in the housing for powering different lamp wattages. The lamp head module is wired to power either incandescent or HMI lamps depending on the power cord connector used. The lamp head module is sealed for use in wet environments including underwater use.
Claims26
A lamp head module for assembly to a variety of light reflectors, comprising:
- a housing, a transparent lamp enclosure substantially opaque to ultraviolet radiation and having an open end fixed to said housing and an opposite closed end, and a lamp socket supported to said housing for holding a lamp in said lamp enclosure;
- said lamp head module being interchangeably assembled with any light reflector selected from the group comprised of a parabolic reflector, a cyclorama reflector and a soft reflector, said any light reflector being detachable from said module without separation of said lamp enclosure from said housing.
A lamp head module for assembly to a variety of light reflectors, comprising:
- a housing, a transparent lamp enclosure substantially opaque to ultraviolet radiation and having an open end fixed to said housing and an opposite closed end, and a lamp socket supported to said housing for holding a lamp in said lamp enclosure;
- an igniter in said housing connected to said lamp socket;
- a power input connector on said housing including a first and a second pin set, said first pin set being connected for supplying power to said socket exclusive of said igniter and said second pin set being connected for supplying power to said igniter, whereby said lamp socket is operative for powering either an HMI lamp or an incandescent lamp by applying electrical power to either said first or said second set of pins of the power connector, respectively.
A modular lighting system comprising:
- a lamp module having a housing, a transparent lamp enclosure substantially opaque to ultraviolet radiation and having an open end fixed to said housing and an opposite closed end, and
- a lamp socket supported to said housing for holding a lamp in said lamp enclosure;
- a parabolic reflector having a reflector axis;
- a cyclic reflector having a reflector axis;
- and
- means for supporting said housing interchangeably to said parabolic reflector and said cyclic reflector with said transparent lamp enclosure in alignment with said reflector axis of either reflector;
- whereby said lamp module can be combined with one said reflector to make either a parabolic light fixture or a cycle light fixture.
A cycle light comprising:
- a cycle reflector including a cylindrical reflector between opposite end reflectors and a reflector axis of said cylindrical reflector;
- a pair of lamp modules, each lamp module having a housing, a transparent lamp enclosure substantially opaque to ultraviolet radiation and having an open end sealed to said housing and an opposite closed end, and a lamp socket supported to said housing for holding a lamp in said lamp enclosure;
- and
- a bracket assembly for releasably supporting said pair of lamp modules independently of each other with said lamp enclosure of each module in generally parallel relationship with said reflector axis;
- such that said lamp modules are each separately removable from said bracket assembly for individual use apart from said cycle reflector.
A lower cost method of providing illumination on a movie set, comprising the steps of:
- providing a plurality of lamp modules, each module having a housing, and a lamp socket supported to said housing for holding a lamp;
- providing a plurality of parabolic reflectors each having a reflector axis;
- providing a plurality of cyclic reflectors each having a reflector axis;
- assembling a desired number of parabolic light fixtures and cycle light fixtures by combining some or all of said lamp modules with corresponding reflectors selected from said plurality of parabolic reflectors and said plurality of cyclic reflectors;
- and
- electrically powering said some or all of said lamp modules for illuminating said movie set;
- whereby said lamp modules may be placed in service interchangeably as either parabolic light fixtures or cycle light fixtures thereby to reduce the total cost of set lighting.
A lower cost method of providing illumination on a movie set, comprising the steps of:
- providing a plurality of lamp modules, each module having a housing, and a lamp socket supported to said housing for holding a lamp;
- providing additional pluralities of reflectors selected from the group comprised of parabolic reflectors, cycle reflectors, flat reflectors and soft reflectors;
- assembling each of said lamp modules to corresponding reflectors selected from said additional pluralities to make up a desired assortment of modular light fixtures;
- and
- electrically powering said lamp modules for illuminating said movie set with said light fixtures;
- whereby the total cost of set lighting is reduced by using a modular lighting system.
A modular method of providing lighting fixtures, comprising the steps of:
- providing a plurality of lamp modules, each module having a housing, and a lamp socket covered by a lamp enclosure substantially opaque to ultraviolet;
- providing a plurality of light reflectors selected from the group comprised of parabolic reflectors, cycle reflectors, flat reflectors and soft reflectors;
- installing in each of said lamp modules a lamp selected from the group comprised of incandescent lamps and HMI lamps;
- and
- assembling each of said lamp modules to corresponding reflectors to make up a desired assortment of modular light fixtures.
