Definitions
- the invention relates to a rod-shaped battery-operated lamp with a Collective lens arranged at the end, at least one light-emitting diode as light source and partially disposed between the converging lens and the light source transparent image carrier.
- Such a lamp is known from DE 200 06 761 U1.
- This lamp has between the light source and a converging lens at least partially opaque or spectral color filtering disc-shaped bodies in the light beam path, this body preferably a light-transparent slide image or a partially punched-out film, for example made of metal or plastic can.
- This is to be used to use the lamp as an advertising medium use, with which company emblems, product presentations or the like can be projected as images are.
- the flashlight in mini flashlight format becomes one small format slide projector that can be carried easily.
- the one in the beam path arranged body should be insertable into the housing via a slot.
- the converging lens or that used instead of the converging lens Lens system for focusing the image can be moved longitudinally axially in the housing be arranged.
- the introduction of an image carrier difficult, which also lock bad leaves, so that its longitudinal axial fixation and vertical alignment in the beam path is unsatisfactory.
- quick interchangeability is also common of the image carrier is not required.
- the arrangement of the image carrier is also intended Enable the generation of optically sharp images in the beam path.
- the image carrier is longitudinally axial movable sliding sleeve arranged, with their longitudinal axial displacement both the distance of the light source to the converging lens and the distance of the image carrier is changeable to the converging lens.
- this lamp can be used as a small-sized flashlight be formed when a light emitting diode (LED) is used as the light source becomes.
- LEDs have several advantages over conventional light bulbs. On the one hand, light emitting diodes are much more impact and impact resistant than light bulbs other small volume. After all, the power consumption of light emitting diodes compared to light bulbs considerably lower, so that the battery capacity is spared or the batteries used can be used longer as electricity storage.
- the light cone generated can be optimally adjusted. additionally enables the sliding sleeve, which has a partially light-transparent body, the Picture of the object in question on a wall or on the floor.
- plastic discs are suitable as partially light-transparent bodies, for example represent a company logo. This has compared to that on the lamp housing printed, glued or otherwise embossed company logos Advantage that the logo itself is protected against external mechanical influences.
- the flashlight is switched on, there is a corresponding one when illuminated canvas-like surface a surprising picture that looks original. This picture however, does not interfere with the usual use of a flashlight as a means of lighting.
- the sliding sleeve can preferably be displaced axially in a guide sleeve, wherein the guide sleeve is connected to a sleeve forming the lamp head is on the end face of the converging lens is attached.
- the sleeve forming the lamp head has an internal thread that can be screwed to a corresponding external thread of the guide sleeve is. This measure creates a hidden connection that is not visible from the outside created between the lamp head and the guide sleeve. This connection is also detachable, for example if an exchange of the collecting lens is required.
- the sliding sleeve has at least two, preferably four, longitudinal notches, extending from one end extend longitudinally axially over part of the sliding sleeve so that the sliding sleeve is expandable from this end.
- This measure serves to keep the image carrier in the sliding sleeve easier to insert and fix there.
- To the image carrier in The outer casing of the sliding sleeve has a better fixation of the inserted position at the expandable end there is also a circumferential ring groove which defines the longitudinal notches crosses and into which a retaining ring can be inserted. This retaining ring fixes the spreading end the sleeve mentioned.
- the sliding sleeve has the light emitting diode on it facing end with a smaller-diameter sleeve-like extension a thread, which is preferably an external thread.
- This thread engages into a corresponding thread of the lamp housing part in which the light source is attached.
- the external thread of the sleeve-like extension also engage in an internal thread of an adapter that connects to the lamp housing is screwed.
- This adapter is also sleeve-shaped and protects the light emitting diode or the light emitting diodes when screwed in. By Unscrewing the adapter can expose the LED, for example if this LED is defective and needs to be replaced.
- the flashlight has a lamp housing 10, the back with a unscrewable cover 11 is completed. After unscrewing this The battery can be inserted into the cover of the battery drawer or inserted.
- the lamp housing there is also a holder for attached a light emitting diode 12; which is protected by an adapter.
- the adapter 13 has on its outer jacket 14 an external thread (not shown), which is screwed into a corresponding internal thread of the lamp body.
- the Outer jacket 14 is larger in diameter than the outer jacket of the forward directed adapter part.
- the adapter 13 On its inner jacket, the adapter 13 has in the front Area an internal thread that corresponds to an external thread of the sleeve-like Extension 15 is formed. This external thread (not shown) the sleeve 15 can be screwed into the internal thread of the adapter.
- the extension 15 mentioned is part of a sliding sleeve 16 which is in a guide sleeve 17 is axially movably mounted.
- the sliding sleeve 16 has four longitudinal notches 18, which, however, only extend over part of the sliding sleeve 16.
- the sliding sleeve 1 6 has a circumferential annular groove 19 on its front directed end which crosses the longitudinal notches 18. This circumferential annular groove 19th serves to receive a ring through which the end is designed as an expansion sleeve Sliding sleeve 16 is fixable in the radial direction.
- the sliding sleeve 16 can easily be spread out.
- the image carrier is as far as possible in the direction of the extension 15 indented. If necessary, an inner jacket annular groove can also be provided in the sliding sleeve 16 be provided, in which the image carrier "snaps". As a rule is however, this is not necessary since the image carrier is in the sliding sleeve 16 can hold frictional pressure well. To prevent the picture carrier is then moved from its frictional position to the lamp head inserted a ring in the annular groove 19, for. B. an elastic O-ring.
- the image carrier is designated by 20 in FIG. 1.
- a converging lens 22 is attached to the front by means of an O-ring 23 fixed.
- a lens system can also be made up of a collimator Scattering lens can be understood as it is from optical instruments is basically known.
- the lamp is over a push button 24 on and off.
- This switch 24 can optionally covered by the clip 25, which is rotatably arranged on the lamp housing 10 so that the switch 24 prevents accidental operation is protected.
- the lamp head 21 can be moved longitudinally axially be (see Fig. 3). In a specific embodiment, the length is the lamp approx. 8 cm and can be increased by approx. 1 cm to 9 cm by pulling out the lamp head 21 are enlarged:
- the lamp head 21 also has an internal thread that with the (not shown) external thread is screwed to the jacket part 28.
- This threaded connection is designed so that the guide sleeve 17 except for a small ring piece 29 completely "disappears" in the lamp head 21.
- the sliding sleeve is 16 in the guide sleeve and thus also longitudinally axially within the lamp head slidable so that the distance between the image carrier and the converging lens is changeable.
- the extension 15 has an outer diameter that for Inner diameter of the guide sleeve 17 leaves an annular area, so that Smaller diameter piece of the adapter 13 can be pushed back and forth in this ring area is, with the corresponding longitudinal axial movement of the sliding sleeve 16 is moved in the guide sleeve 17.
- the lamp head pushed in the smaller diameter part of the adapter 13 is completely in the guide sleeve 17 inserted, which in turn is firmly connected to the lamp head 21. Pulling the lamp head 21 out, due to the threaded connection of the Adapter 13 with the sliding sleeve 16, the smaller diameter front jacket piece of the adapter 13 exposed.
- the lamp head When fully assembled, there are known optical laws only one position in which the object of the picture carrier on a wall or canvas is sharply depicted.
- the lamp head To meet the condition that the reciprocal values the object distance and the image distance the reciprocal of the focal length of the Correspond to the converging lens, the lamp head must be moved depending on the illuminated area be what is easily possible with one hand by the lamp body 10 placed in the hand and with the thumb and forefinger the lamp head in the suitable position for a sharp depiction of the subject is moved.
- the guide sleeve and the sliding sleeve can optionally be replaced as a unit around a different unit with a different image motif to be able to.
