Lamp designed for mobile use

Technical area

The invention relates to a lamp which is designed for mobile use. The lamp comprises at least one light source and a can-shaped housing.

State of the art

Such lamps are known by the applicant and referred to as DOT-it® lamps.

Such a lamp is a modern light source, which is designed for mobile use and has a self-contained integrated battery for power supply. In addition to the mobile applicability, this portable lamp can be attached to a variety of objects. For this purpose, this lamp comprises on its backside an adhesive tape which can be reversibly used. To change the battery, it is necessary to loosen this tape and open the housing on the back of a small opening by means of a relatively small precision screwdriver. This is relatively expensive and always requires the use and presence of such a specific screwdriver.

Presentation of the invention

The present invention is therefore based on the object, a generic lamp in such a way that the usability and usability can be made even more flexible and independent. This object is achieved by a lamp having the features of claim 1.

A lamp according to the invention is designed for mobile use and comprises an internal energy source and at least one light source and a can-shaped housing in which the components of the lamp are arranged. The lamp itself is therefore essentially also formed can-shaped. The housing is formed at least in two parts and comprises an upper part and a lower part. In addition, the housing has a closure device, which closure device is designed such that a relative movement between the upper part and the lower part for opening or closing the housing without tools is feasible. With this configuration, the lamp can be easily opened or closed without a screwdriver or the like and only with the hands. The two parts of the housing can thus be joined without auxiliary tool for closing the housing or at least partially separated to open this housing. Especially with such lamps, which are portable and can be easily carried, thereby flexible use and mobile usability can be done much more independent. In particular, location can be performed independently and at any time a simple change of a power supply of the lamp. Especially with such mobile usable lamps, it is therefore no longer necessary by the invention, always carry an auxiliary tool to perform in case of need, in particular a battery change can and thereby ensure further operation can.

Thus, when the housing is open, in particular when the upper part is removed, an energy source, in particular a battery of the lamp, is preferably accessible, in particular removable or usable.

The upper part preferably has a region which is permeable to the light generated by the light source and which is exchangeable. This translucent area is thus detachable from the upper part, in particular without additional Auxiliary tools. As a result, in particular, the mobile use of the lamp can be made more independent and the lamp can be qualitatively improved. Because in a simple and low-effort way, even with a damaged, for example, scratched or destroyed, permeable area this easily be replaced and the full functionality of the lamp without loss of quality to be restored. Extensive repair or even disposal of the lamp after such damage to this permeable area can be prevented.

In particular, it is provided that this replacement of the translucent area can only take place with the top removed. In the assembled state of the housing, the transparent area is thus firmly fixed and can neither be removed, nor can it fall out of the housing and thus be lost.

It can preferably be provided that the light-permeable region is releasably secured to this upper part on the inside of the upper part, which faces the inside of the housing. For example, a plug connection or a holder can be provided here via tabs or latching elements.

In addition, a multifunctional lamp can be ensured by this embodiment, since different light-transmissive areas can be used. These can be designed so that they have different light transmissions, whereby various uses and usabilities of the lamp are given. In addition to the use of light-transmissive areas, which have different light transmissions, also different colors can be generated. Thus, it can be provided that light-transmissive areas with different colorations can be used, as a result of which also different light colors of the lamp can be achieved by a simple and low-cost replacement of these light-transmitting areas. Also - A -

By the possible use of the lamp can be significantly extended.

Preferably, the transparent area is formed as an optical element. It may be provided that the light-transmissive region is formed as a lens, for example as a convex or concave lens. The translucent areas, in particular the lenses, may also be colored. This also allows individual application options can be achieved.

The closure device preferably has at least two locking steps, it being possible to set specific operating states of the lamp depending on the set locking step. Advantageously, the functionality of the lamp can be significantly increased thereby. Thus, the lamp can be turned on in a first Arretierungsstufe and turned off in a second Arretierungsstufe. It can also be provided that the light brightness of the lamp and thus the light emission of the lamp is adjustable depending on a respective set locking stage. It can be provided that the lamp has at least two light sources, wherein in a first arresting stage, only one light source is activated for emitting light and both light sources are activated for emitting light when setting the second arresting stage. In addition to such a discrete brightness adjustment, a continuous light emission can also be generated. In this context, the lamp can be continuously dimmed depending on the set locking levels.

It can also be provided that the light-permeable region has a plurality of partial regions which have different light permeabilities and / or colorations. In particular, in the case of such an embodiment of a light-transmissive region, it is also possible to position different subareas of the light-transmissive region directly above a light source of the lamp by setting different locking steps, thereby producing individual light emission. NEN and lighting effects can be generated. Therefore, a single, compact lamp can be used for a wide variety of individual settings and uses.

Preferably, the closure device is designed as a screw cap. It can be provided that at the mutually facing edge regions of the upper part and the lower part circumferentially threaded to be able to realize this screw. A robust and easy to handle design can be formed, which is also low maintenance. In particular, in such an embodiment of the closing device closing the different locking stages can be made possible in a simple manner. In particular, by a simple rotation, the continuous change of the light emission and thus a continuous dimming can be carried out.

Last but not least, twisting of the translucent area can also be made easy even with a screw-type closure device. Especially when this translucent area has several differently colored and / or formed with different translucency subregions, a rapid and low-cost changing the position of these subregions can be made possible.

The closure device can also be designed as a latching device. This locking device as well as the Schraubverschlussvorrichtung can be realized so that the lower part and the upper part can be completely separated from each other. Under a locking device, for example, a bayonet lock is to be taken. The locking elements can be designed so that they are easily accessible from the outside and can be easily operated with fingers to separate the two parts. In addition, it can also be provided that the upper part and the lower part are firmly connected to each other via a hinge joint on one side and can be moved relative to each other only by a pivoting or tilting movement. To the position-stable assembly of these two parts and Thus, to be able to achieve a tightly closed housing, one or more additional holding elements, for example latching elements, can be provided. By this configuration can be prevented that one of the two parts is lost when the housing is open.

Preferably, a fastening device for fastening the luminous element to an object is arranged on the housing, in particular the lower part. The fastening device can be arranged detachably on the housing. It can also be provided that the fastening device is integrated in the lamp. For example, an adhesive bond, in particular an adhesive tape, may be arranged on this rear side of the lower part. It can be provided that the fastening device comprises at least one magnet. It can also be provided that the housing, in particular the lower part, is at least partially magnetized. An additional attachment of a separate magnet to the housing is not required by this embodiment. As a result, the compactness can be maintained and the weight of the lamp does not increase. In addition, however, simple hook elements or plug-in elements can be provided as a fixture. Further, a suction button or a Saufnapf be provided, whereby an attachment to glass surfaces or the like is possible. Combinations of these fasteners may be provided. The attachment to a wide variety of objects can be guaranteed.

Preferably, the upper part and the lower part have a substantially identical shape. In particular, it can be provided that the two parts forming the housing are substantially the same size. Under a can-shaped housing of the lamp according to the invention mentioned above, for example, both a disc-like configuration and a square configuration understood. Preferably, the can-shaped housing is designed so that a flat housing is realized. In this embodiment, it is preferably provided that the height of the housing is small. ner than the width and the length or the dimensions in the plane perpendicular to the direction in which the height of the lamp is measured.

Short description of the drawing (s)

An exemplary embodiment of the invention is explained in more detail below with reference to a schematic drawing. The single FIGURE shows a perspective view of a lamp according to the invention.

Preferred embodiment of the invention

The figure shows a lamp 1, which is designed for mobile use and for attachment to various separate objects. The lamp 1 comprises a can-shaped housing, which is constructed in the exemplary embodiment as a flat housing and is designed disc-like. This can-shaped housing comprises a top part 2 and a part 3, which have substantially the same shape and size. In the illustrated assembled state of the lamp 1 and thus in the closed state of the housing sits the upper part 2 and the lower part 3 substantially congruent to each other. The shape of this can-shaped housing is designed so that the height (z-direction) of the lamp is smaller than the radial dimensions of the lamp 1 in the x-y plane. The very flat design of the housing is realized.

In the housing four light sources 4, 5 and 6 are arranged, which are formed in the embodiment as light-emitting diodes. It can be provided that these plurality of light sources 4 to 6 are designed to emit the same light color. However, it can also be provided that the light sources 4 to 6 are designed to generate light, each having a different color. In the exemplary embodiment, the light sources 4 to 6 are each designed to produce white light.

In addition, a reflector 7 is arranged in the housing. On the upper side of the upper part 2, a light-transmissive region 21 is formed, through which the light signals of the light sources 4 to 6 are emitted. This translucent area 21 is realized in the embodiment as a clear glass element. In addition, this translucent region 21 is formed as a separate element to the upper part 2 and detachable from the upper part 2. As a result, the light-transmissive region 21 can easily be exchanged in the event of damage or destruction or even if it is desired or required to use another light-transmitting element.

However, the replacement of this translucent region 21 can only take place in the embodiment, when the upper part 2 is lifted from the lower part 3 and thus the housing is opened. The light-permeable region 21 is detachably fastened to the side of the upper part 2 facing the interior of the housing and thus of the lamp 1.

In the exemplary embodiment, the upper part 2 and the lower part 3 are connected by a screw cap 7. The parts 2 and 3 are plate-like and at the edges of these plate-shaped parts 2 and 3 each circumferential threads are formed in order to screw the upper part 2 with the lower part 3 can. By a simple rotational movement in the direction of the arrow P, the housing and thus the lamp 1 can be easily opened and closed. By this configuration, the access to the interior of the lamp 1 and thus also to an energy source, not shown, of the lamp 1, which is formed in the embodiment as a battery, possible. With the housing open and thus separated upper part 2, this energy source is accessible and can be removed.

In addition to the two-part design of the housing, the separation and assembly of these two parts 2 and 3 without any auxiliary tool, for example, without a Feinmechanikschraubendreher done. At the end of the lamp 1 opposite the light-permeable region 21 and thus at the bottom 31 of the lower part 3 is an unillustrated provided fastening device. By this fastening device, the lamp 1 can be attached to a wide variety of objects.

In addition, it is provided in the exemplary embodiment that the closure device or the screw cap 7 has different locking stages, whereby different operating states of the lamp 1 can be set when setting these locking stages. Thus, it can be provided that only one of the light sources 4 to 6 is activated at a first discrete locking position and thus at a first rotational position between the upper part 2 and the lower part 3. If a second locking position is exceeded 4 to 6 and thus reaches a second rotational position, a second light source is switched on. Analogously, this can be done at a third rotational position for the third light source 4 to 6. It can also be provided that, depending on the specific arresting stage and thus in the exemplary embodiment, the light emission of at least one of the already activated light sources 4 to 6 can be changed depending on a specific rotational position. In addition, it can also be provided that a continuous rotation of the light emission of at least one of the light sources 4 to 6 can be generated by a continuous rotation. The lamp 1 is thus adjustable by a simple rotation of the parts 2 and 3 relative to each other in their brightness and thus easily dimmable. In addition, it can also be provided that a flashing function can be generated by setting a specific arresting stage, at least in the case of a light source 4 to 6. The electronics required for carrying out these functions of the lamp 1 is integrated in the lamp 1. It may be provided that, for example, metal tongues are arranged in the screw cap 7, wherein upon reaching or exceeding these due to the relative rotation between the upper part 2 and the lower part 3, the respective locking stages or rotational positions are detected and the associated functionalities are activated. As a fastening device may be provided in addition to an adhesive tape and a magnet. As a result, the attachment can be made possible even on metallic soiled surfaces. In addition, the realization by a magnet is less susceptible to wear.
