- FIG. 1 is an elevational view of a lighting fixture constructed in accordance with the principles of the present invention.
- FIG. 2 is a sectional view partly fragmented and illustrating the details of construction of the lighting fixture according to the present invention.
- FIG. 3 is a sectional view taken along the section line Ill-Ill of FIG. 2.
- FIG. 4 is a sectional view taken along the sectional line lV-IV of FIG. 2.
- the present invention contemplates a sealed lighting fixture which is operable under varied environmental conditions and yet which may be quickly and readily unsealed when required for purposes of repair or replacement of parts. This is accomplished by providing a transparent tubular member surrounding a lamp end sealed at both ends, with one of the ends having an adjustment for varying the tightness of the seal. The lighting fixture is opened by unscrewing a threaded sealing cover to gain access to the lamp and other serviceable parts of the fixture.
- the invention further contemplates a reflector positionably mounted within the sealed lighting fixture; and a plurality of such sealed fixtures connected end to end and in parallel relation to provide a continuous string wherein the light emanates from a line extending substantially along the string.
- FIG. I there is illustrated a composite lighting fixture 10 which is of the fluorescent type and which includes a plurality of light fixtures each having a lamp mounting chamber 11 and a ballast chamber 12.
- the composite lighting fixture 10 is constructed so that interconnections between the individual fixtures and their attachment to a wall is accomplished by a number of supporting members 13. It is to be noted that the lighting fixture 10 is arranged such that the ballast chamber 12 of the individual fixtures is located behind a lamp mounting chamber of the respective fixture so that the composite lighting fixture 10 provides a substantially continuous illumination from and between each of the lamp mounting chambcrs l I. This is accomplished by providing the support member 13 connected to one of the fixtures at a junction 14 between the lamp chamber 11 and the ballast chamber 12. and to another fixture at an end 15 of the respective lamp chamber ll.
- the composite lighting fixture 10 still provides illumination emanating substantially from a single reference axis passing through all of the fixtures.
- the support members I3 support the individual fixtures in parallel relation to each other in such a manner that the lamp mounting chambers ll appear to be in substantially end to end connection.
- This construction also maintains an angle between the composite lighting fixture l0 and a wall upon which the fixture I0 is mounted such that the glare usually occuring in continuous end to end connected illuminating sources is substantially reduced.
- FIG. 1 maintains a substantially continuous illumination, the undesired effects resulting from usual fixtures with this characteristic have been reduced.
- the support member 13 includes a bracket 16 having an upper portion 17 for mounting one fixture thereto, and a lower portion 18 for mounting the end 15 of another fixture.
- the upper mounting portion 17 is formed with a first flange 19 which accommodates a ballast chamber cover20 and a threaded conduit 22.
- An input power supply line is connected via a conduit and associated conduit connections in the usual manner to the entrance 22.
- a shelf 24 with a right-angled end 26, the shelf being supported within the chamber 12 by a pair of bolts 28 passing through the rightangled end 26 and threadably engaging a wall 30 in the chamber 12.
- the ballast chamber cover 20 is adjustably positioned and connected to the flange 19 by a wing nut 32 passing through an aperture in the cover 20 and threadably engaging an end 34 of the shelf 24.
- a gasket seal 36 is fitted within a cavity 38 in the flange 19 so that as the wing nut 32 is tightened on the end 34, the cover 20 is reliably sealed to the flange 19.
- ballast 40 of the type commonly associated with fluorescent lamps is mounted on the shelf 24. Also mounted on the shelf 24 is a terminal block 42 to supply the required interconnecting points between the ballast wires, the lamp wires, and the incoming power line. Immediately ad jacent the terminal block 42 there is mounted a fuse cutout panel 44 for fusing the incoming lines to the end of each individualfixture.
- the lamp mounting chamber or compartment 11 is shown fragmented in FIG. 2, however, when also viewing FIG. I in conjunction therewith it can readily be seen that the lamp compartment 11 extends from the upper mounting portion 17 of one support member 13 to the lower mounting portion 18 of the second support member 13.
- a lamp compartment end 46 at the upper mounting portion 17 of the support member 13, and the lamp chamber end 15 at the lower mounting portion 18 of the support member 13 are illustrated to represent the lamp compartment ends of each of the separate individual fixtures.
- a lamp 48 of the fluorescent type is supported within the compartment 11 by a socket 50 mounted to a wall 52 by the screws 54.
- the other end of the lamp 48 is supported by a spring biased socket 56 which includes a pair of ears 58 with a lip 60 engaged under a rim 62.
- a coil spring 64 acts on the base 66 of the lamp 48 to urge the lamp towards the socket 50 and thereby securely making the necessary electrical connection.
- a cylindrical transparent sleeve 68 formed of a heat-resistant glass such as Pyrex".
- the sleeve 68 being of a heat-resistant material permits the light fixture to be utilized in extreme environmental conditions. Both ends of the sleeve 68 are sealed in relation to the support members 13 at each end thereof.
- the sleeve 68 is nested within a gasket 70 located in a cavity 72 of the flange 74 in the upper mounting portion 17.
- sleeve 68 is held by a gasket 76 lying within a sealing chamber 78 of an adjustable nut 80.
- the adjustable nut 80 is threadably mounted on the lower mounting portion 18 of the support member 13 so that tightening of the nut 80 on the portion 18 will tighten the seal on the sleeve 68. It can be readily appreciated that although the lamp 48 is mounted on the rim 62 of the nut 80, the spring biased socket 56 and the spring 64 operate to urge the lamp 48 towards the socket S regardless of what the final position of the nut 80 might be.
- the reflector 82 is mounted within the lamp compartment ll intermediate the sleeve 68 and the lamp 48 .
- the reflector 82 is formed of aluminum and includes at opposite ends thereof a pair of biased locking rings 84. Two of these rings are located at each end of the lamp compartment 11 and each has an end 86 attached to the reflector 82, a bumper 88 which in the normal locked position rests against the sleeve 68, and a grip 90.
- the bumper 88 would lie outside of the circumference defined by the surface of the reflector 82.
- the locking ring 84 may be biased so that upon release of the grip 90 the bumper 88 will be firmly urged against the sleeve 68 to maintain the reflector 82 in the desired position.
- Forming an integral part of the reflector 82 is a wireway 92 which allows wires from the ballast chamber l2 and via a C- shaped cutout 94 between the walls 30 and 52, to pass through the wireway 92 and then to the socket 56.
- the C-shaped cutout 94 on the wall 52 extends for approximately l80 to accommodate different positions of the reflector 82 and the wireway 92. It can be seen in FIG. 3 that the sleeve 68 with the reflector 82 locked inside thereof can be rotated so as to position the reflector 82 where secured. This positioning of the reflector 82 can be accomplished through an angle to l80 with the wireway 92 cooperating with the cutout 94.
- the lamp compartment end is sealed by means of a lamp compartment cover 96 which includes an O-ring-type seal 98 seated within a threaded end 100, the threaded end 100 threadably engaging the adjustable nut 80 at the threads 102 such that tightening of the cover 96 sealingly urges the seal 98 in firm contact with a wall 104 of the nut 80.
- a locking arrangement for locking the adjustable nut in position includes a chain 106 secured at an end 108 to the cover 96 and a bolt 110 captured by the other end of the chain 106. The bolt 106 is threaded into the lower mounting portion 18 and for locking purposes is tightened against the threads 102 of the nut 80.
- the lighting fixture according to the principles of this invention is constructed so that ready access can be obtained to the various parts thereof the replacement or repair purposes, even with the fixture providing a reliable seal of the lamp, wires, etc. under various environmental conditions
- the ballast chamber or compartment 12 it is only required to unscrew the wing nut 32 from the end 34. This allows repair or replacement to be performed on the ballast 40, the terminal block 42, the fuse cutout panel 44, the conduit entrance 22, or the lamp socket 50.
- access to the lamp compartment ll is readily provided by unthreading the cover 96 from the adjustable nut 80.
- the lamp 48 may then be removed for replacement or service by depressing the cars 50 so as to disengage the lips 60 from beneath the rim 62 and pulling the socket 56 from the lamp base 66. The lamp 48 may then be disengaged from the socket 50.
- ballast is provided for I each lamp to minimize the loss of illumination in case of ballast failure. Further. all wiring necessary between the ballast. fuses, input supply line and the lamp is contained within the sealed lamp unit.
- the following procedure is outlined.
- the support members 13 including the brackets 16 are mounted to the desired wall 112 such as a tunnel wall, by appropriate mounting means 114.
- the proper ballast 40 and the necessary wire interconnections between the conduit entrance 22, the ballast 40, the terminal block 42, the fuse cutout panel 44, and the lamp socket 50 are then performed.
- the glass sleeve 68 with the reflector 82 already locked in position therein is next mounted to the upper mounting portion 17 and the lower mounting portion 18 within the adjustable nut 80.
- the ballast cover 20 is then placed in sealing position, and the nut is adjusted to provide a reliable seal at both ends of the sleeve 68.
- the lamp 48 is then placed within the compartment 11 and is guided by means such as a number of fingers I16 mounted within the sleeve 68 until the lamp 48 engages the socket 50.
- the socket 56 and the appropriate connections thereto is then placed in locking engagement with the nut 80, and the cover 96 is finely threaded onto the threads 102 until the seal 98 is adequately urged against the wall 104.
