Abstract

A sun lamp assembly, including a head panel 1 containing a plurality of parallel fluorescent tubes 3 located in front of a reflector 14, in which the heavy choke or ballast units associated with the fluorescent tubes are located remote from the head panel, thereby permitting a thinner, lighter and cooler head panel to be manufactured. The panel may conveniently be pivotally mounted at the end of a cantilever arm 4 which in turn may be pivotally mounted on an upright stand assembly 5. The choke or ballast units may be located in the stand 5 or base 6. Capacitors, starter switches or timers may be retained in the head panel. <IMAGE>

Description

SPECIFICATION Sun Lamps The present invention relates to lamps and is especially concerned with lamps that emit ultra violet light in the area of the spectrum that allows tanning of the human body to occur without concomitant burning.
A wide variety of sun lamps employing fluorescent tubes which emit ultra violet light at the correct frequency for tanning are now available. These are in the form of "sun beds" and "over head" systems. Such lamps generally employ fluorescent tubes of about 2 meters in length.
Short tubes, 450 mm to 650 mm long, have recently become available and as a result portable systems can now be manufactured for carrying, for example, two to eight tubes.
Owing to the weight of the head panel carrying the fluorescent tubes, an extremely robust and expensive stand having a heavy base is required for lamps in which the head panel is suspended from a a cantilever arm for "over head" use, that is with the tubes substantially horizontal or inclined towards the user. The need for this particular stand construction arises as a result of the presence, in the head panel, of the power unit which may include choke or ballast units normally present in the ratio of at least one unit for each two fluorescent tubes, capacitors, starter switches and a time switch. Such units frequently weigh more than 3 times the weight of a single tube.
In such lamps of this construction the head panels are of a deep construction in order to avoid high surface temperatures, and radiate an undesirable amount of heat, owing to the presence of the chokes or ballast units in the power unit.
I have now found that a lamp assembly for "over head" use may be provided using a lighter stand and a head panel of thinner construction if the power unit is remote from the head panel, eg placed in the stand base or any part of a column or columns extending therefrom for supporting the head panel, the power unit then being connected to the tubes through suitable electrical conductors of appropriate length.
The present invention, therefore, provides a lamp assembly comprising a frame assembly carrying a plurality of fluorescent tubes located in front of a reflector to provide a head panel, and a power unit including ballast or choke units associated with the said fluorescent tubes, the power unit being positioned remote from the head panel and the ballast or choke units connected to their respective fluorescent tubes by suitable electric conductors.
The head panel may be attached to a vertical support such as a wall and the power unit located on a horizontal surface such as a floor.
The choke or ballast units may be contained in the base of the panel assembly, in the column assembly or as a unit remote from the panel assembly.
If required, items such as capacitors or starter switches or timers may be retained in the head panel adjacent the fluorescent tubes.
In one embodiment the head panel is carried at one end of a cantilever arm, which arm may comprise two parallel members, the other end of the said arm being mounted on a substantially upright column.
The head panel may be pivotally mounted at the one end of the cantilever arm and the other end of the said arm similarly pivotally attached to said column assembly.
In an alternative form, the cantilever arm and column assembly may be formed in a single unit and comprise, for example, a form of flexible tubing capable of maintaining a given form and of supporting the head panel.
The fluorescent tube starter switches and holders may also be conveniently located in the base or column assembly of the stand thus improving the compactness of the head panel design.
Preferably the lamp assembly is wired with one choke or ballast per fluorescent tube, all the tubes being wired in parallel and without starter switches, or one choke or ballast per pair of fluorescent tubes wired in series using starter switches, the pairs of tubes being wired in parallel with the power source. These wiring methods significantly limit the number of conductors required between the head panel and the choke or ballast and are especially useful when the chokes or ballasts form a unit remote from the lamp assembly.
The invention will now be more fully described with reference to the accompanying drawings in which: Figure 1 is a perspective view from the front of one embodiment of the present invention: Figure 2 is a perspective view from the rear of figure 1; Figure 3 is a perspective view of a second embodiment, and Figure 4 is a perspective view of a third embodiment.
In the drawings like parts have been identified by the same reference numerals.
Referring to figures 1 and 2, a sun lamp consists of a head panel 1 comprising a frame 2 which carries 6 fluorescent tubes 3 mounted in parallel and behind which is located a reflector 4.
Tube starter switches (not shown) are located within the head panel 1 along one side of the frame 2. Head panel 1 is supported by a cantilever arm 4 slidably mounted on a vertical stand 5 to allow adjustment of the height of the head panel, a device (not shown) for locking the panel at the correct height being included, which stand extends from a base member 6 having forwardly extending feet 7 to provide stability. Three chokes and a timer (not shown) are located in the base 6 and a timer knob 8, positioned for easy access, is positioned on the top of the base 6. The assembly is wired for connection to a mains electricity supply through conductors 9.
Panel 1 is mounted on arm 4 for pivotal movement about an axis perpendicular to the axis of fluorescent tubes 3 the movement being between a position where the tubes are horizontal (as illustrated) and a position in which the tubes are vertical, and for pivotal movement about an axis running through the rear member of frame 2 parallel to tubes 3, whereby the head can be tilted upwardly or downwardly to any required inclination.
In the embodiment shown in figure 3 the head panel 1, carrying fluorescent tubes and a reflector (not shown), is mounted on a cantilever arm 10 provided with a vertical portion 11 having an extending portion 12 which is a sliding fit into a hollow vertical stand member 13. The height of panel 1 is adjusted by raising or lowering section 12 within stand 13 and the required position secured by locking member 15.
Stand 13 is mounted on base 6 for pivotal movement about a vertical axis.
In the embodiment of figure 4 the head panel 1 (containing a reflector and fluorescent tubes) is carried on a cantilever arm 20 which is, in turn, attached to a flexible stand member 21 which allows for adjustment of the position of panel 1 in the horizontal and vertical planes.
In the embodiments of figures 3 and 4 the chokes, starting switches and timer are located as described with reference to figures 1 and 2.
The present invention is equally applicable to sun lamps for use with full length sun beds or for use with the shorter tubes in a portable assembly.
Although the present invention is particularly concerned with provision of sun lamps containing fluorescent tubes emitting a particular ultra violet spectrum of light, the invention may also be applied to any lamp including fluorescent tubes and in which the tubes may be carried at the end of a cantilever arm carried on a stand.
Sun lamps manufactured incorporating the present invention have the advantage that, because the head panel is lighter and is of a lower temperature than those in current manufacture, there is less likelihood of the equipment collapsing and causing injury or burns to a user.
