Definitions

• the task of the invention is to provide cost-effective fluorescent lighting assemblies that are geared both in dimensions and design toward the present demands Because cost is a factor, the apparatus of the present invention uses a minimal amount of components, packaged in a rational manner to ensure rapid and simple installation A preferred embodiment of the present invention configures a portion of the lamp assembly as a semilamp, enabling the retrofitting of existing lamp assemblies that do not operate electronically.
• a new reflector lamp element in which the reflector element is designed as a self-supporting, extruded or drawn hollow section, which is at least partially closed on the ends by two plates, each end plate provided with at least one socket for mounting and delivering power to a fluorescent bulb, and in which the electronic components of the ballast are situated within the hollow section.
• the end plates can be fitted with additional sockets in order to mount multiple fluorescent tubes within the lighting assembly.
• the extruded hollow sections can also be equipped with guide strips to secure a circuit board to the electronic ballast, at minimal additional cost.
• the arrangement of spring contacts on the circuit board that lead directly to the sockets of the fluorescent lamps is possible and is a feature of a preferred embodiment.
• a particularly advantageous variant of the reflector lamp assembly according to the invention consists of designing it as a semilamp, which means configuring it so that it is provided on both end surfaces with pin bases and is insertable into an existing lamp apparatus that is still not operated electronically in order to retrofit it to advantageous, energy-saving high-frequency operation.
• the pin bases arranged on the end surfaces be mounted to rotate by about 90°. This expedient avoids the otherwise cumbersome insertion into the sockets by pivoting the entire semilamp. In a preferred embodiment of the present invention, only the rotatable pin base need be rotated
• Figures 1 to 4a show a reflector lamp assembly in accordance with the present invention, said assembly adapted to hold two fluorescent tubes
• Figure 1 is a longitudinal section and Figure 3 a cross section of this double lamp assembly
• Figure 2 is a frontal view of the double lamp assembly Figures 4 and 4a are cross sections through the extruded section
• Figures 5 to 10 show a semilamp assembly comprising a reflector element, a single fluorescent tube or bulb, and a pair of electrical contacts on each end of the reflector element
• Figure 5 is a side view of this semilamp assembly
• Figure 6 is a longitudinal section through the apparatus of Figure 5
• Figure 7 a frontal view of this semilamp assembly Figure 8 is a view of the end plate
• Figure 9 is a view of the end plate with the rotatable base removed
• Figure 10 is a cross section of the semilamp
• the designations employed in the examples of the base/socket system G5 and G13 correspond to the worldwide standardized systems, but also are not to be interpreted as restrictive However, these are the most widespread systems
• the base/socket system G5 is proposed in particular for the new high-performance fluorescent lamps with 16 mm diameter The description refers to this system for this reason
• the invention can naturally also be used for any other base/socket system, even a future one
• Lamp element (30) consists merely of two essential parts, namely the extruded hollow section (1) and two identical end plates (2) that can be mounted on both ends
• Lamp element (30) includes the circuit board (3) with eight identical elastic spring contacts (8), which are soldered directly into the circuit board (3) and naturally the actual electronic components of the ballast The remainder are small parts, for example, for connection of line voltage, which can be selected from an enormous variety of standardized finished parts
• the hollow section (1) is shown in Figure 4 and additionally shows the possibility of providing a transparent cover (1 1) insertable in grooves (22), which is not closed on the ends for reasons of ventilation
• Figure 4a shows a variant for a situation in which only a narrow circuit board (3) is provided and an additional stiffening of the hollow section (1) is desired with intermediate wall (19)
• This type of reinforcement is advised in an extruded plastic section, since the wall thicknesses can be reduced on this account in order to save material
• Figure 1 also shows the simple installation, for example, with spring snaps (5) on the guide surfaces (4) of end plates (2)
• the end plates (2) are simply pushed into the hollow section (1) until the spring snaps (4) snap into the recesses (6) in the hollow section (1)
• the spring contacts (8) previously soldered onto circuit board (3) are pushed into the downward open sockets (9) and the circuit board (3) then threaded into the guide strip (7) and installation of the electronics is thus completed
• connection to line voltage in many cases, for example in the US occurs by loose wires that are directly soldered to the circuit board (3), a special depiction of the connection terminals is dispensed with An enormous number of standard plug connections or terminals that are applied to the circuit board (3) are available for selection
• T5 lamps require an electronic ballast and have a G5 pin base with a different pin spacing
• Figure 3 shows in a scale section how even somewhat clumsy electronic components, like transformers (15) or equivalently designed inductive chokes can be accommodated in hollow section (1) beneath the reflector
• a possibility thus far unutilized is a compact design in a hollow section
• Semilamp assembly (40) is suitable for converting existing lamp apparatus that is still equipped with obsolete, inductive ballast, to significantly better electronic lamps
• pin bases (10) arranged on end plates (2) of assembly (40) serve for this purpose
• Pin bases (10) have a pair of lamp element pins (13) which correspond to the standardized G13 base/socket system, so that they can be inserted in practically any of the presently available lamps
• the depicted example assumes that one also intends to utilize the enormous advantages of the new T5 fluorescent tubes and the depictions are shown accordingly
• pin bases (10) have an inwardly-facing socket (9) adapted to mate with the pins (13) of T5 lighting tube (14) All subsequent descriptions naturally also apply to a semilamp with two fluorescent lamps (14) according to Figures 1 to 4 and vice-versa
• FIG. 10 shows a side view of a semilamp with hollow section (1) for which all the aforementioned details, like incorporation of circuit board (3), guide surfaces (4), spring snaps (5), etc apply without restriction
• the arrangement of pin base (10), which is mounted to rotate in sleeve (18), is different
• Figure 8 shows a view of the end plate before insertion into an existing lamp Element (30) has a pair of lamp element pins (13) which are oriented in the direction of insertion into the lamp assembly and lock the semilamp in the lamp being retrofitted by rotation of pin base (10) in the direction of arrow (21) Rotation
• Figure 9 shows a special design configuration of end plates (2) in order to be able to produce them with simple dies
• the sockets (9) are designed open from the side of the rotatable pin base (10) so that the connection wires from the electronics to pins (13) required as feed lines can also be led out Since this opening is covered after insertion of the rotatable pin base (10) by it, no additional cover is required to protect the voltage- conducting spring contacts (8)
• the rotatable pin base (10) is expediently equipped with stops to limit the rotational movement and with snap connections in known fashion.
• Figure 10 is section A-A through the semilamp and shows that even with limited width, sufficient space is available for the electronic components SMD component (16) finds sufficient space beneath circuit board (3) so that the dimensions of the circuit board (3) can be kept small
• a lamp design according to the invention in a protective and stable hollow section offers enormous advantages
• the number of parts in such a lamp is reduced to a minimum
• the material and work expense offered not only cost advantages, but also mean a significant unburdening of the environment by lower energy consumption
