Definitions

  • the invention relates to a compact, largely eye-safe light module comprising an electrical energy source, a voltage converter and a radiation source for electromagnetic radiation. Furthermore, the invention relates to a pocket tool, in particular pocket knife or plate-shaped tool card, having a housing with at least one receiving area and at least one, from a storage position within the receiving area, in a position of use outside the receiving area movable functional part, and with a light emitting module for emitting electromagnetic radiation, which is arranged in the housing and can be put into operation by means of an actuating element.
  • a light module In tools of everyday use, especially in pocket tools, there is often the desire that is arranged on or in this tool a light module.
  • a light module may be formed, for example, to illuminate the working area of the hand tool or to act as a light pointer.
  • the light-emitting element Due to the often very small amount of space for hand tools, the light-emitting element is usually formed only by a power supply and a light source, a drive circuit or a safety circuit is omitted for lack of space.
  • the power supply is usually formed by a chemical element, in particular by a commercially available battery.
  • chemical elements have the disadvantage that the provided output voltage changes in the course of operation, in particular it is continuously lower; this voltage drop is described by the so-called discharge curve. Another disadvantage is that the discharge curve depends on the type of chemical element.
  • a lighting module should deliver as constant as possible an optical light output over the entire operating time, which is not feasible with such a power supply.
  • the output voltage of the chemical elements is technologically limited, but some lamps require a supply voltage higher than the output voltage of a single chemical element, for example, multiple chemical elements used in series. It is also possible to convert the low output voltage of the chemical element by means of a voltage converter to the required increased supply voltage of the lamp.
  • a voltage converter is usually characterized in that it increases the input-side supply voltage by a certain fixed factor and makes it available on the output side.
  • the known solutions have the disadvantage that in the case of improper or wanton use of an improper energy source, in particular one with a higher output voltage, the lighting means applied to a large supply voltage, whereby the bulb can be damaged or destroyed. Due to the increased supply voltage of the light source, it can also happen that the electromagnetic radiation emitted by this exceeds a power limit and thus, in an illumination of the human eye by the emitted light beam, due to the excessive radiation power to damage the retina.
  • the US 5,627,414 A discloses a folding pocket knife with a laser pointer.
  • the laser pointer is formed by a laser diode and a plurality of battery cells being arranged in a housing part which can be swung out of the pocket knife.
  • the laser diode is put into operation by the circuit between the battery cells and the laser diode is closed by an actuator. When the circuit is closed, the supply voltage of the laser diode is equal to the output voltage of the series-connected battery cells.
  • the US 6,027,224 A also discloses a pocket tool which, however, includes two bulbs.
  • a light source is designed as a laser pointer
  • the second light source is designed as a light cone emitting light source.
  • the document discloses that with each closed circuit, the first and second lighting means is connected directly to the battery cells.
  • the object of the invention is now to form a compact light pointer in such a way that the intended use and an unwanted influence of the illuminant emitted by the electromagnetic radiation emitted to the human eye, damage to the retina is reliably prevented.
  • the invention further relates to a pocket tool which comprises a compact light pointer, damage to the eye being largely prevented by the light beam emitted by the light pointer.
  • the object of the invention is achieved in that a power limiter for controlling the emitted electromagnetic radiation is present.
  • the power of the electromagnetic radiation emitted by the radiation source usually depends on the supply voltage applied to the radiation source. From the manufacturer of the voltage source is usually specified a maximum supply voltage with which the emitted electromagnetic radiation does not exceed a certain power limit. Based on the physiological properties of the human eye, the optical radiant power was classified based on the wavelength of the radiation. In the case of bulbs which may be used in public without additional protection or which are used in public, the radiation power must be so low that the natural protective mechanism of the eye (eyelid reflex) is sufficient, even with direct illumination of the eye no damage to the retina occurs.
  • the power limiter according to the invention can now take into account a plurality of operational specifications and thus in any case keep the power of the emitted radiation below a dangerous power limit value.
  • the user of a lighting module according to the invention can thus be sure that in each operating state, a largely harmless to the eye electromagnetic radiation is emitted.
  • the power limiter comprises a first detection element for electromagnetic radiation.
  • This first detection element may, for example, be designed to measure the power of the electromagnetic radiation emitted by the radiation source.
  • the power limiter at any time the currently emitted radiation power knows. Due to the technological structure of the radiation source, the emitted radiation power is subject to an aging process, ie even with a constant supply voltage, the emitted radiation power will change over the course of the operating time. Furthermore, the emitted radiation power is usually also dependent on the temperature of the radiation source. The knowledge of the currently emitted radiation power is therefore essential in order to be able to form an eye-safe light-emitting module.
  • a power limiter comprising a control circuit has the decisive advantage that this power limiter can evaluate continuously recorded operating data and can influence the emitted radiated power in a targeted manner via the control loop.
  • a control loop has the advantage that a continuous adaptation of the radiant power in the sense of a desired-actual comparison is possible.
  • control circuit may include a protection circuit, which ensures a reliable shutdown of the radiation source when exceeding a power limit.
  • Photodiodes have the particular advantage that their spectral efficiency is very precisely adjustable. This makes it possible, for example, to largely suppress the surrounding electromagnetic radiation and to measure only the power of the electrical radiation emitted by the radiation source. Variations in the ambient brightness thus advantageously have no influence on the determination of the emitted radiation power.
  • the first detection element can also be designed as a photoresistor or phototransistor.
  • all detection elements are possible, which emit an electrical output signal or change the electrical parameters due to an incoming electromagnetic radiation.
  • a significant advantage is obtained if the first detection element and the radiation source are integrated in one module.
  • This advantageous embodiment allows the power of the emitted electromagnetic radiation directly at the radiation source to capture, which in particular disturbing, the measurement falsifying environmental influences are largely suppressed.
  • the training has the further advantage that can be realized by today's technologically possible high integration density, a very compact design of the claimed module. With regard to a wide use with high quantities, the training according to the claim has the further advantage that the module can be produced particularly inexpensively.
  • the radiation source and the first detection element can be matched to each other, whereby the emitted radiation power can be maintained very accurately.
  • the first detection element and the radiation source can be formed by semiconductor components. If the two elements are integrated in one module, both elements have the same temperature, which is of particular importance with regard to the common-mode parameters of semiconductors.
  • the power limiter Since the power of the radiation emitted by the radiation source electromagnetic radiation usually depends on the supply voltage of the radiation source, one obtains a significant advantageous development when the power limiter is designed to influence the output voltage of the voltage converter.
  • This advantageous embodiment of the power limiter is able to influence on the regulation of the output voltage of the voltage transformer, the power of the emitted electromagnetic radiation.
  • Another advantage of a claimed embodiment is that the output voltage of the voltage transformer is largely independent of the output voltage of the power source.
  • the voltage converter is designed as a step-up and / or as a step-down converter.
  • This design makes it possible to implement a large output voltage range of the power source to the required, stable supply voltage of the radiation source.
  • the voltage converter operates in this operating state as a step-up converter.
  • a significant advantage for the formation of an eye-safe light-emitting module is obtained if the voltage converter is also designed as a step-down converter. Improper use of the light module, for example by using an energy source with too high an output voltage, the radiation source would emit electromagnetic radiation with too high power, which can result in unintentional illumination of the eye to damage the retina, because the allowable power limit exceeded becomes.
  • a voltage converter designed in accordance with the invention is capable of reducing an input voltage which is up to 400% above the nominal value to a supply voltage of the radiation source which complies with the limit value.
  • Another advantage of the claim trained trained voltage converter is that the voltage conversion is carried out very low loss. Especially with regard to mobile devices, it is of crucial importance if the limited available energy of the energy source is optimally converted into electromagnetic radiation. Particularly in the case of voltage adaptation from a higher to a lower voltage level, a step-down converter designed according to the claims has the decisive advantage that the voltage adaptation does not require a power-consuming, resistive voltage divider.
  • Another advantage is that the adaptation to a too high or too low input voltage level is carried out automatically by the voltage converter without operator action. Thus, even with a deliberate manipulation of the energy source is always ensured that the emitted electromagnetic radiation does not exceed a harmful performance limit.
  • the emitted radiation power of a radiation source usually also depends on the temperature of the radiation source. Due to the demanding training in the Power limiter has a temperature detection module, one obtains the advantage that changes in the emitted radiation power due to different operating or ambient temperatures of the light module can be compensated. As a result of the operation of the radiation source, this will usually be heated, as a result of which the so-called operating point can shift and thus the emitted radiation power can exceed a power limit value. In addition, the radiation source can continue to heat due to the increased emitted radiation power, which can lead to a rocking process, which can lead to damage or destruction of the radiation source.
  • the temperature detection element can be designed to reliably switch off the radiation source at an excess temperature thereof and thus to prevent damage to the radiation source.
  • a radiation source can usually emit electromagnetic radiation in a larger power range.
  • the maximum power of the emitted electromagnetic radiation is determined by the fact that the energy source emits a maximum voltage, in particular, this is the no-load voltage of the mostly used and possibly connected in series chemical elements.
  • An application according to the invention in which the power limiter has a power configuration module now has the decisive advantage that the configuration of the emitted radiation power no longer depends on inaccurate and changed voltage values.
  • the power configuration module advantageously further ensures that unauthorized operation or manipulation of the radiation source is prevented.
  • operating parameters for the radiation source are stored in the power configuration module.
  • these operating parameters an unambiguous and unchangeable configuration of the radiation source is possible; in particular, the safety-relevant power limit value of the emitted radiation can thus be defined defined.
  • These operating parameters can be saved in the power configuration module in such a way that manipulation by unauthorized third parties is prevented, which represents a decisive advantage with regard to the desired eye protection.
  • An embodiment of the radiation source as a laser diode has the advantage that the emitted monochromatic electromagnetic radiation has a high intensity. Due to their technical design, laser diodes have the advantage that the emitted light beam is particularly advantageous for the formation of a light pointer, since in most cases only a few complicated collimator lenses are required.
  • a laser diode which emits an electromagnetic radiation having a wavelength of 600 nm to 750 nm, preferably 655 nm, has the special advantage that the emitted radiation is in the visible optical range, furthermore laser diodes which radiate in this area are widely used and thus available at low cost. Due to the physiology of the eye, a red light beam has the further advantage that it is already clearly perceived even at low radiation power. It is also advantageous that a laser diode designed according to the claims is used in many mass-produced articles and thus also the possibly additionally required peripheral components are available at low cost.
  • a significant advantageous development is obtained when a cylinder attachment is arranged on a flange-like portion of the laser diode.
  • Laser diodes are known to emit a highly divergent and non-circularly symmetric beam.
  • To achieve the widest possible beam with a small beam expansion of the laser diode is usually followed by a beam shaping optics.
  • To prevent unwanted lateral radiation and mechanical fixation of the beam shaping optics was Laser diode so far mostly arranged in a cylindrical attachment.
  • the disadvantage of such an arrangement is that the inner diameter of the cylinder cap must be large enough to accommodate the laser diode and fix it. Due to the required mechanical stability of the cylinder cap, this has an outer diameter which is significantly larger than the largest outer diameter of the laser diode, which is disadvantageous for the most compact possible construction.
  • the cylinder cap is arranged on a flange-like portion of the laser diode, thereby achieving a significant reduction of Aussendruchmessers the cylinder head, in particular, the outer diameter of the thus formed luminous element is equal to the maximum diameter of the laser diode.
  • Another advantage of the claimed embodiment is that due to the larger contact area between the housing of the laser diode and the cylinder cap better heat dissipation from the laser diode is possible.
  • a beam-shaping optical system in particular collimator optics, is arranged in the cylinder attachment.
  • the object of a collimator optics is to align non-directional or divergent beams of a light source in parallel and thus to form a light beam, which widens only very slightly over longer distances and thus ideally can be used as a light pointer.
  • An appropriately designed laser diode has the advantage that it is classified under the laser hazard class 1 or 2 and is therefore approved for general use in the public.
  • a lighting module according to the invention is intended to be used both in daylight and in darkness. In the case of high ambient brightness, a higher luminance of the same is required for reliably recognizing the light beam than is necessary in the dark, for example at night. Due to the claimed training is achieved in an advantageous manner that the light beam emitted by the radiation source has sufficient intensity to stand out visibly against the environment. In the case of low-intensity ambient lighting, this has the advantage that the radiation power of the signal source is reduced below the standard predetermined level, as a result of which the energy requirement of the radiation source is advantageously reduced. Through this continuous adjustment of the emitted radiation power, the duration of use of the energy source can be significantly increased, which is of decisive advantage for compact, mobile application areas of the lighting module.
  • An embodiment in which the energy source emits a voltage of typically 1.55 V has the advantage that this energy source is formed by widely used and therefore inexpensive usable chemical elements, in particular by button cells.
