Definitions
- the invention relates to a device for receiving and electrical contacting of a light source in a headlamp according to the preamble of claim 1.
- a headlight for film, studio, stage lighting and other applications which has a headlight housing, which serves to receive a luminous body, a transparent cover in the form of a protective screen or a lens disc and a reflector.
- lamps or luminous bodies are burners or lamps, preferably single-ended discharge lamps, in a vertical or horizontal mounting position, that is, in each case perpendicular to the optical axis, or in the axial installation position, that is, in the optical axis used.
- the lamps comprise a gas-filled glass body with electrodes arranged therein, a lamp base through which the supply lines are led to the electrodes, and two or more contact pins which are located at the end opposite the glass body the lamp base are arranged.
- the contact pins are inserted for connection to a voltage source in the sockets of a lamp socket connected to the lamp housing, with a close fit between the sockets and the contact pins for the high current levels of the lamp current to be transmitted is necessary.
- the contact pins serve, for example, discharge lamps which are socketed on one side as fastening means for the discharge lamp. Since the size of the discharge lamps and in particular the dimensions of the glass body and the lamp base increases with increasing lamp powers, the lamps have such a size for larger lamp powers that, in particular in the case of a horizontal mounting position of the discharge lamps, considerable forces are exerted on the power supply in addition to the power supply Mounting contacts acting contact pins are exercised.
- the disadvantages of the exclusive storage of the lamp via the contact pins affect not only the static range on the size of the lamp, but especially in the dynamic range when transporting a headlamp or its operation with jerky pivoting movements, shocks on the lamp housing and the like.
- the receiving device of jaws that surround the lamp base and means the adjusting device in an open position in which the lamp cap is released, and in a locking position in which the lamp cap is fixed, are adjustable.
- the adjustment device consists of a pawl with two geometrically similar oblique surfaces. Chen, which rest on the upper and lower jaw so that when an adjustment of the pawl, the jaws are spread radially.
- the bulbs are inserted through the reflector from the front of the headlamp when the front cover is open and clamped in the bulb socket behind it. Only when the bulb centric and just applied to the end stop of the bulb socket the clamping device may be operated, otherwise damage to the bulb socket, the sockets or the bulb socket and the contact pins caused by breakage, flashovers or corrosion.
- the bulbs must be observed from the front when inserting into the bulb holder to the light, d. H. on mutually aligned contact pins of the bulb and the sockets of the bulb socket to use while on the other hand, the operator must hold the bulb with one hand and center and operate with the other hand, the clamping device whose controls are usually located on the side of the headlight housing , However, the operator can no longer be sufficiently far in front of the headlight with larger headlight housings with a correspondingly large headlight housing in order to simultaneously observe the straight onset of the light source and to be able to operate the clamping device.
- Another problem is that on the one hand a for the reflection of the light emitted by the light optically cheaper and therefore the smallest possible reflector opening is desired, but on the other hand, the visual inspection upon insertion of the light in the light bulb holder difficult because it obstructs the view on the bulb holder, especially if the illuminant is already partially immersed in the luminous ffen charged is used, so that the operator can no longer recognize whether the bulb is inserted or tilted correctly and consequently contact the pins of the bulb, the sockets of the bulb socket insufficiently.
- a shift of the clamping device for non-positive and / or positive clamping of the bulb socket to the front of the headlight housing would not lead to any significant improvement in visual inspection when inserting the bulb in the bulb holder, since the visual inspection would be hindered anyway by a narrow reflector opening, so that only one An enlarged reflector opening would allow an improved visual inspection taking into account a deteriorated beam reflection and worse optical properties of the headlight.
- JP 09-185978 A For detecting a correct fit of a lamp cap in a lamp holder, it is known from JP 09-185978 A to provide a recess in the lamp base, at the bottom of a torsion spring is arranged, whose ends are bent upwards and engaging projections, which engage in corresponding engagement recesses in engage the inner wall of the lamp socket. If the lamp base is inserted into the lamp socket, this leads to the rotation of the torsion spring and upon engagement of the engagement projections in the engagement recesses, an acoustic signal is generated.
- a device for detecting an insufficient connection of a lamp cap of a discharge lamp with a lamp holder which consists of a connecting cable and a mounting bracket, which can be connected to the lamp socket only if the lamp cap completely with the lamp socket is connected.
- a lighting device with a unilaterally quilted radiator in which a connection of the radiator is excluded with a socket when the radiator is unsuitable.
- the socket for receiving the radiator is connected to a sensor element which receives magnetic or optical pulses, while the socket facing part of the base is provided with a marking element which emits magnetic or optical pulses which are received by the sensor element after the marker has been stimulated to deliver the pulses by an excitation means.
- a discharge lamp is known, the base of which is connected to a socket which contains a device for generating a high voltage from an AC voltage.
- the socket has a recess at the end of which a high voltage contact is arranged, which is connected to a protruding from the base of the discharge lamp pin. Furthermore, in the recess of the socket contacts for preheating the cathode as well as with a circumferential lead collar of the lamp cap corresponding contacts are provided with which a signal applied to the contacts of the socket signal is shorted. Short-circuiting the contacts signals that the lamp socket is correctly seated in the socket that releases the high voltage.
