Lamp unit with an electric lamp. The lamp 1 is installed in a reflector 4 and, together therewith, installed in a bulb enclosure 5. <IMAGE>
Description
LAMP UNIT WITH AN ELECTRIC LAMP
The present invention relates to a lamp unit with an electric lamp.
Heretofore, lamp units were constructed from merely a lamp and bulb enclosure. This construction is encumbered by the disadvantage in providing a poor efficiency in the output of light emissions, inasmuch as an excessive amount of light it lost through dispersed or scattered light. Other lamp units are equipped with an unsatisfactorily located reflector. In this instance, either the bulb enclosure itself forms the reflector, or a poorly adjusted reflector is inserted into the bulb enclosure, in which the reflector, in most cases, includes a rearwardly facing opening through which an excessive amount of light is reflected rearwardly without being used.
Accordingly, it is an object of the present invention to provide a lamp unit of the above-mentioned type which, while avoiding the previously encountered errors and disadvantages, is highly efficient and which can be automatically and inexpensively produced in large quantities through the intermediary of presently available lamp manufacturing installations, and for which purpose there can be made use of currently available types of standard components.
The foregoing object is inventively attained in that the lamp is installed in a reflector and, together therewith, installed in a bulb enclosure. In this manner, there can also be obtained the advantage that without the necessity of having to take any additional measures, it is possible to realize a complete protection against electric-shock, and with the utilization of suitably selected materials there can also be suppressed harmful ultraviolet radiations.
Further advantages and modifications of the invention can now be more readily ascertained from the following detailed description thereof, taken in conjunction with the accompanying single figure of drawing illustrating an exemplary embodiment of the inventive lamp unit.
In connection with the drawing, reference numeral 1 identifies the lamp; reference numerals 2 and 3 pertain to the connection of the lamp with a reflector 4 through the formation of a connection 10, 11 which is preferably a welded or soldered connection, but which can also be constructed from a plug connection, the former being arranged within a bulb housing or enclosure 5; and reference numeral 6 designates the base of the bulb enclosure 5, whereas reference numeral 7 identifies the threading on the base. Reference numeral 8 identifies the front disc portion of the bulb enclosure 5; and reference numeral 9 identifies the rearward portion thereof.
The lamp 1 is installed within the reflector 4, and in combination therewith, is assembled or installed in the bulb enclosure 5.
The bulb enclosure 5, pursuant to the representation in the drawing, possesses a reflector shape; however, it can also be round, pear-shaped or tubular. The threading 7 can consist of a screwthread, or possess the configuration of a bayonet-type connector.
The bulb enclosure 5 can be constructed from a single part, or from a plurality of parts; for example, which are assembled and interconnected through adhesion, soldering, sintering or being melted together.
The bulb enclosure 5 is expediently consisted of a transparent material, preferably glass, which is adapted to withstand the operating temperature.
The bulb enclosure 5 can be melted together with a glass footing or base portion at the threading end thereof, or can be openly fastened in the base 6 through adhesion or clamping. The bulb enclosure 5 can be filled with air; or, for example, the bulb enclosure 5 can be filled with a gas, preferably such as nitrogen or argon.
The bulb enclosure 5 can also be evacuated. Moreover, it is also possible that the bulb enclosure 5 be filled with an inert gas including an addition of hydrogen.
The bulb enclosure 5 can be clear, partly or entirely coated, matted or frosted, colored, or equipped with a reflective coating. Moreover, the bulb enclosure 5 can possess a clear or colored front disc portion 8 and a reflective coating in the rearward, preferably conical bulb part 9. Finally, the bulb enclosure 5 can also incorporate a coloring in the bulb materials through the mixing in of colorants; for example, neodynium.
The lamp unit can include an installation for correlating the power supply voltage with the operating conditions or requirements of the lamp 1. The installation can be located either within the base 6, between the base 6 and the bulb enclosure 5, or in the lamp unit itself. Another possibility consists of in that the installation is positioned on the lamp unit and arranged in an adapter.
Expediently, the lamp 1 consists of a usual evacuated or gas-filled incandescent lamp. The lamp 1 can also be a halogen lamp with a deformation provided on one side thereof. Furthermore, the lamp 1 can be a discharge lamp in a construction which is closed at one or both ends thereof.
It is advantageous when the lamp 1 is accurately focused within the reflector 4.
The front disc portion 8 of the bulb enclosure 5 can be provided with facets for a controlled guiding of the light.
The reflector 4 can be configured either elliptically or parabolic. The surface of the reflector is expediently matted or frosted, faceted or smoothly constructed, and provided with a reflective coating.
The reflective coating on the reflector 5 can be created in a manner such that specific ranges of the wavelengths from the irradiated light are either absorbed or transmitted towards the rear.
Finally, the reflector 4 can be equipped with a protective covering which is either clear, matted or frosted, faceted, colorated, or coated.
