Definitions

  • the invention relates to a lamp, in particular a living room, table or flashlight with a lamp head having a arranged in a hollow reflector light source, which projects through an aperture of the hollow reflector with its plug and / or terminal contacts.
  • Living room, table or flashlights conventional design are equipped with light bulbs, which have the disadvantage that at relatively high power consumption, only a relatively small portion of the energy used to generate light is exploited.
  • xenon lamps higher luminous efficiencies or energy-saving lamps more cost-effective modes are possible, but even here optimizations are desirable.
  • Flashlights In flashlights, it is known to arrange the light bulb approximately in the region of the focal point of a concave reflector. In most cases, such a reflector is a so-called parabolic mirror with which the light output of the flashlight is to be increased.
  • An incandescent filament of a flashlight bulb emits the light in the switched-on state in all directions, so that by reflection the light not emitted in the direction of the frontal lamp head opening is directed by single or multiple reflection in a substantially longitudinal axial direction and thus is usable. Flashlights are also known in the prior art, which have a lijnsaxial displaceable reflector to achieve different radiated light cone.
  • This displacement can either via a longitudinally extending guide, by a translatory pushing movement or by a rotary movement take place, in which the reflector is conditionally displaced according to the thread pitch by the rotation.
  • the light bulb inside a reflector rigidly connected to the lamp head can also be moved longitudinally via a slide or the like, which however is structurally more complicated.
  • the change in the emitted light beam shape results depending on the reflection of the light emitted from the bulb beams on the reflector inner shell, wherein a substantially parallel Lichtstrahlausfer is present when the bulb or its filament is in the focal point of the concave mirror.
  • US Pat. No. 4,783,735 discloses a flashlight which has a reflector and two light bulbs, light-emitting diodes or laser diodes arranged here at different locations, through which shadow effects, such as occur only with a light bulb, are to be avoided.
  • the reflector used to achieve this goal and the transparent cover, through which the light exits, are complicated in design and, since the radiation is perpendicular to the flashlight longitudinal axis, the lamp is cumbersome to handle.
  • a lamp with a light-emitting diode is known, which is arranged in a Hohtreflektor the light-emitting diode protrudes through the back with their connection contacts an opening of the hollow reflector.
  • the hollow reflector projects around the light-emitting chip of the light-emitting diode with a conical reflector part.
  • This lamp has a light emitting diode as a light source, which is surrounded by a hollow reflector whose aperture is the same size of the sheath contour of the inserted light-emitting diode except for a small clearance or tolerance.
  • the position of the hollow reflector is determined by its outer shell design and the design of the lamp head inner shell both centered and longitudinal axial unambiguously in the lamp head. At least the height of the light emitting chip of the light emitting diode arranged hollow reflector is designed substantially conical.
  • the hollow reflector serves to increase the luminous efficacy.
  • the main beam direction of the light emitting diode is limited to a relatively small Kegelwinkelanno, but the laterally radiated and absorbed without the use of a reflector of the lamp head inner surface area radiation amounts are not insignificant.
  • the LED centered when sliding the reflector, ie, the light-emitting diode is erected in each case at about slightly bent wire-shaped power connectors, so that they exactly aligned longitudinally axial.
  • the hollow reflector itself is centered on its outer shell design, which is adapted to the lamp head inner shell design, in a corresponding manner.
  • the hollow reflector can in terms of its design at its the Diode-facing reflector side essentially have the known prior art shapes, as already hereby an increased light output can be achieved.
  • the hollow reflector has a cup shape with a conical reflector shell at the level of the light-emitting chip.
  • the hollow reflector preferably has a cylindrical stepped outer surface, which has the same diameter as the stepped cylindrical inner lamp shell, except for a small clearance or tolerance, whereby the hollow reflector is secured over the annular step of the cylinder jacket parts at a correspondingly formed stage in the lamp head inner shell against falling out. With its bottom, the hollow reflector is supported on a holder for the diode.
  • the hollow reflector may also have a conical outer shell, which rests tightly all around except for a small clearance or tolerance on the uniform inner cone shell of the lamp head. A safeguard against falling out of this conical jacket provides a corresponding stop on the front edge of the lamp inner jacket.
  • the conical reflector part at the level of the light-emitting light-emitting diode chip forms with the common hollow reflector and lamp housing longitudinal axis an angle of 10 ° to 45 °, preferably 30 °, wherein the hollow reflector in addition to the first, the light emitting chip of the light emitting diode surrounding reflector part in the range of larger cone diameter For this purpose arranged parallel second conical shell portion.
  • the first shell part that from the luminous point becomes sideways, i. radially radiated light forward, i. reflected to the opening of the lamp head.
  • Any further scattered light components in the radial direction which are radiated sideways from the tip of the light-emitting glass body, are reflected by the second conical jacket part in a corresponding manner.
  • a cylindrical casing part can be arranged between the first and the second conical casing part. This broken cone shape has the advantage of a reduced diameter, which is particularly desirable in miniature flashlights.
  • diodes occur in the radial direction of scattered light components substantially at the level of the light-emitting chip and on the front dome-shaped glass body tip, whereas light emissions in the remaining glass body areas are negligible.
  • the cone-shaped cylinder design described provides an ideal compromise between the smallest possible reflector diameter and the optimum light output.
  • the hollow reflector may be formed so that it projects slightly beyond the front end of the diode glass and / or that the light-emitting diode is arranged at least 0.5 cm behind the open end of the lamp head. The latter variant is particularly recommended if the diode is to be protected against external shock or impact or other mechanical damage.
  • the aperture of the hollow reflector at the bottom rear has an annular extension for receiving the lower Diode glass body paragraph.
  • the hollow reflector may additionally comprise latching means on its bottom periphery, which comprise the back of the diode base. Such locking means ensure that the hollow reflector is fixed after being pushed onto the diode body with this, so that, if necessary, can be dispensed with the further longitudinal axial fixings or stops for the hollow reflector.
  • the above-described embodiment can be designed both as a flashlight, in particular as a rod-shaped flashlight, but also as a table or living room lamp.
  • the voltage required for diode operation may be supplied via a transformer supplied from a conventional 220V or 110V socket.
  • diodes In all of these embodiments, the advantage given by diodes is used that, compared to conventional incandescent lamps, only about 13% of the energy can be used at the same brightness.

  • the design of the individual hollow reflectors and the position of the diodes in these reflectors corresponds to the above-described training.
  • the outer shell profile formed by the honeycomb-shaped body of the reflectors can be designed such that it is adapted to the inner shell of the lamp head. Any "interspaces", as they arise in the juxtaposition of circular cross-section profiles can be filled in the way of injection molding production, so that the outer shell profile of the one-piece body, for example, circular, elliptical or otherwise shaped.
  • the individual reflectors are not fixed, but by an angle up to 45 °, preferably up to 30 °, pivotally mounted.
  • the beam direction of individual units can be set specifically, as is already known in principle residential lighting equipment with conventional radiators.
  • the individual reflectors (each including a diode) can be arranged side by side on a line, an arc, a circle, rotationally symmetrical about a central point or in any geometric contour to each other.
  • the rod-shaped lamp housing design has several advantages.
  • such a rod-shaped lamp can be produced in a miniature format whose size is determined essentially by the batteries used and the areas required for the arrangement of the switch. If, instead of a pressure or push switch, a rotary switch which can be arranged on the lamp housing cover, the lamp radius can be further minimized.
  • the rod-shaped lamp can be inserted into a ring or cylindrical holder of a lampshade, so that the lamp can be used in case of need as a table or living room lamp or flashlight.
  • a previous disadvantage has been seen in the fact that conventional diodes either only (almost) monochromatic light, e.g. in blue, red, green, orange) or emit red, blue and green mixed colors, which have only approximately the character of the "white light". The latter is only possible if one uses correspondingly many diodes with different emission spectra.
  • Remedy such LEDs can create in which the light-emitting LED chip in a plastic mass with fluorescent or phosphorescent particles is embedded. Fluorescence and phosphorescence are physically combined as so-called luminescence phenomena; the main difference is only in the light duration. About Lumineszenz bine can be achieved that the light emitted by the LED chip light (eg in blue color corresponding to about 480 nm) excites luminescent particles. The absorbed radiation is then completely or partially re-emitted in more or less short time, but the emitted light can be at most as short-waved as the absorbed. This leads to a spectral shift of the light emitted by the luminescent particles (compared to the primary radiation originating from the light-emitting diode).
  • the primary radiation and the luminescence radiation lead to a spectral profile which results additively from the light intensities and which is visible as a mixed color.
  • the disadvantage of previous attempts to attach the luminescent particles in the vicinity of the LED chip is that the small increase in temperature of the LED leads to altered radiation characteristics, in other words, the radiated color of such LED is not thermally stable.

Depending on the desired application thickness, the dipping process can be repeated several times.

The sharpness of the contours remains even with slight displacements of the light-emitting diode from the collecting lens focal point.

  • the twistability or displaceability of the clip is chosen such that in one of the clip positions relative to the flashlight housing jacket of the switch is completely released.
  • the clip is preferably connected to form a one-piece body with a housing shell at least partially comprehensive and possibly biased thereto adjacent ring or partial ring profile body.

Possibly. taking into account any existing spring elasticity of the clip is ensured by this construction that even under high external pressure load the casing or the pressure or push switch facing ring or partial ring profile surface is always spaced from the switch.
  • a partial ring profile body is used, which is resiliently elastic and thus formed spreadable.
