DE9012286U1 - Lamp for illuminating the near and far area - Google Patents

Description

The invention relates to a lamp, in particular for illuminating the near and/or far area, which essentially consists of at least one light source arranged centrally in a reflector, wherein a lens can be connected in front of the reflector.

Lamps are known for illuminating, for example, close and long-distance areas, which have two lamps within a common reflector that can be operated differently for close and long-distance areas. The disadvantage here is that the different radiation from one lamp is obstructed by the other lamp.

Similar lamps are known from the automotive industry, where two lamps with incandescent filaments are present within a common reflector. Such lamps are used, for example, as

·

Halogen or gas discharge lamps and have the disadvantage that they require considerable amounts of energy, especially in order to be able to illuminate a close area properly.

In contrast, the invention is based on the object of creating a lamp which, while saving energy, enables better illumination of the near and far areas and which, in addition, allows a longer burning time, particularly when operated with batteries.

This object is achieved according to the invention in that a further, ring-shaped reflector provided with a further light source is arranged around an inner reflector having a light source.

The reflector, which accommodates a light source in a central or middle arrangement, is expediently designed in a known manner and, depending on the intended use, in the usual parabolic or ellipsoidal reflector. The part of a lamp designed in this way fulfils the function of a spotlight.

In order to focus the light emerging from a reflector constructed in this way, a lens, for example in the form of a step lens or, depending on the application, only a protective glass, can be fitted in front of it and at a distance from the light source.

The further reflector with a further light source is arranged in a ring around the headlight reflector, whereby the light source, for example in the form of a fluorescent lamp, can be designed in one or more parts.

In order to design the light of the outer reflector around the lamp, which has a circular cross-section, for the corresponding intended use, the reflectors are designed to emit the light on one or both sides of the lamp.

In order to focus or scatter the emerging light, it is further planned to assign an annular lens to the annular reflector.

According to various embodiments, it is possible to attach the corresponding lenses to the inner reflector or the outer, ring-shaped reflector or both. It proves to be expedient, particularly when used with a protective glass, to design the lenses as stepped lenses.

A lamp designed in this way has the advantages that ¹ ! it has a good illumination capacity and that the lower energy requirement enables a longer burning time, as is required, for example, in particular for mining lighting underground.

A further advantageous design of a lamp required for various purposes can be seen in the fact that the

Reflectors with a light source are arranged next to each other and are provided with different lenses. In addition, such a lamp can be constructed very small.

Several embodiments of the invention are shown in the figures and are explained in more detail below.

example provided.

The lamp shown schematically in a top view in Figure 1 consists essentially of a reflector 2 in an ellipsoidal or parabolic design in which a light source 1 is arranged in the middle. _Around the reflector 2, as can be seen from the section according to Figure 2 or Figure 3, a ring-shaped reflector 5 is provided in which a further light source 4, for example in the form of a fluorescent lamp, is arranged. The light source 4, which is also ring-shaped, can be designed in one or more parts.

As the sections through Figures 2 and 3 clearly show, the arrangement of the illuminant 4 in conjunction with the design of the reflector 5 can be arranged such that the emitted light occurs on one side or on both sides of the illuminant 4 as shown by the arrows.

As can be seen in the embodiment shown in Figure 3, a protective glass 7 can be installed in front of the reflectors 2 and 5, which in turn is connected to lenses 3, 6 in the form of step lenses. Such an arrangement of step lenses 3, 6 has the advantage of a considerable weight saving.

According to further ideas within the scope of the invention, it is possible, depending on the intended use, to provide only the central reflector 2 or, for example, the ring-shaped reflector 5 with a lens or a protective glass.

Figures 4 and 5 show a further embodiment of a lamp in which two reflectors 2, each having a light source 1, are arranged next to one another within a common housing 8. The lenses 3 to be connected in front of the reflectors 2 are designed differently depending on the lighting of the near or far area.
