Definitions

  • the invention relates to an explosion-proof lamp, in particular a signal and / or signal lamp, with a lamp housing for receiving lamps, which has a support body and a translucent cover connected to it in a pressure-resistant manner.
  • explosion-proof electrical devices in particular luminaires, are used in areas where explosive gas-air mixtures can occur, e.g. B. in oil extraction plants and oil refineries.
  • Flammable dusts such as those that can occur in mines and grinding plants, are also comparable to the explosive gas-air mixtures.
  • Known lights are usually operated with electrical energy and generally consist of a support body, which receives the feed for the power supply and a translucent cover, depending on the type of lamps used, tub, hood or. Has a dome or cylindrical shape.
  • luminaires with different colors for reporting and / or signaling purposes. It is customary for a separate lamp to be provided for each color, the color effect being generated either by appropriately colored lamps or by a screen in the corresponding color with which the lamps are surrounded. It is also known to provide the translucent cover with the appropriate coloring.
  • This object is achieved in that at least two fluorescent lamps are arranged as light sources in the lamp housing, which are individually controllable.
  • fluorescent lamps in a common luminaire housing means that only one luminaire has to be installed, where otherwise the corresponding number of several luminaires is usually required.
  • the fluorescent lamps integrated in the luminaire each have different colors, so that the respectively desired color signal can be called up by the separate activation of the fluorescent lamps.
  • the fluorescent lamps integrated in the lamp are optionally arranged so that their pedestals, which serve to feed the fluorescent lamps, are each arranged in the supporting body, so that only the light-emitting parts of the fluorescent lamps are located in the area delimited by the translucent cover are located.
  • the result is that the desired color can be perceived on all sides, namely all around, by switching on the corresponding fluorescent lamp.
  • the differently colored fluorescent lamps can be arranged quasi coaxially one above the other, ie. H. including their feed base.
  • the desired color signal then appears at a certain distance from the mounting surface of the lamp, d. H. there is a certain sequence of signal colors, similar to a traffic light signal system.
  • the translucent cover is opaque, that is, with cloudiness, for. B. according to DIN 5036.
  • opaque is understood to mean a deliberate clouding of the translucent cover, through which light incident on the outside is diffusely scattered.
  • the opaque formation of the translucent cover can be done either by using cloudy material or by the surface of the translucent cover has a certain minimum roughness, or by introducing an opaque cover, for example as an adhesive film, so that depending on the local conditions there is also an exchange option.
  • the embodiment of the invention can be provided by wiring the fluorescent lamps used with an electronic ballast, as a result of which flickering of the fluorescent lamp is avoided in the starting phase.
  • an explosion-proof lamp 10 is shown with a lamp housing 12, which is composed of a support body 14 and a translucent cover 16.
  • the support body 14 serves to receive the feed devices for the lamps 18 arranged in the lamp 10.
  • lamps 18 commercially available fluorescent lamps with a base on one side are provided, which have a base 17 serving for feeding and a light-emitting part 19.
  • the base 17, the upper part of which can be seen in this illustration, is connected to a feed device, which is arranged in the support body 14 of the lamp 10 and is not shown here for power supply.
  • the support body has a cable duct 13, which is covered to protect against rain or splash or dripping water.
  • the translucent cover which usually consists of pressure-resistant strong glass, can preferably also be made of polycarbonate, as a result of which the weight of the lamp 10 is considerably reduced.
  • the translucent cover 16 shown in FIG. 1 is hood-shaped and, as is customary in the case of known lamps, is connected to the supporting body 14 underneath by means of a bayonet lock. A radially attached to the cover 16 nose 15 receives a screw, not visible here, which serves to prevent rotation for the flameproof cover 16.
  • FIG. 2 shows the top view of the luminaire 10 known from FIG. 1, essentially only the cover 16 having a circular cross section can be seen. Easily recognizable in this display is the arrangement of the lamps 18 in a line next to each other. Furthermore, the locking screw arranged in the nose 15 and serving for the translucent cover 16 to prevent rotation can also be seen in this illustration.
  • the cable bushing 13 is located on the side of the cover 16 facing downward in this illustration.
  • the three lamps could also be arranged at the corner points of a triangle, preferably an equilateral triangle.
  • FIG. 3 shows a lamp 11 which corresponds largely to the lamp 10 shown in FIGS. 1 and 2 and which, in contrast to the lamp 10, is equipped with four lamps 18 instead of three lamps 18.
  • the four lamps 18 are star-shaped, i. H. arranged at the corner points of a square, within the cover 16.
  • the further construction of the lamp 11 corresponds identically to the lamp 10, so that there is no need to go into this further.
  • the other design features are each provided with the corresponding reference numbers.
  • Figure 4 shows an explosion-proof lamp 20 with a flameproof housing 22, which is composed of a support body 24 and a translucent cover 26.
  • the lamps 18 are arranged axially one behind the other, a support arm 21 anchored in the support body 24 in a manner not shown here being provided for holding and feeding it.
  • the translucent cover 26 is a weakly tapered tube whose one end is closed like a dome and the other end is connected to the support body 24 and thus forms a pressure-resistant encapsulation within which the commercially available lamps 18 can be used without further safety requirements.
  • the translucent cover 26 is also secured against inadvertent rotation by a locking screw guided in a lug 25, as a result of which the pressure-resistant encapsulation could be eliminated.
  • the support body 24 is in two parts according to the embodiment shown in Figure 4. It consists of an upper support ring 28, which is connected to the translucent surface, and a base 29 flanged to it, which at the same time has a cable bushing 23 serving for feeding.
  • FIG 5 an electrical circuit diagram for the lamp 10 and 20 is shown, in which a ballast 30, which is arranged in each case in the support body 14 or 24, is connected to the phase P from the supply side and on the supply side to each of the three lamps 18, labeled A, B, C for mutual distinction.
  • the other connections of the lamps 18 are connected via conductors A ', B', C 'to a switching point 32 which is connected to the neutral conductor of the supply network.
  • the switching point 32 is designed such that, depending on the switching position, only one of the three lamps A, B, C can be connected to the neutral conductor N, as a result of which the circuit is closed.
  • each of the lamps 18 used in the lights 10, 11, 20 has a different color, so that depending on the switch position of the switch 32 each only one color lights up.
  • the circuit arrangement shown in Figure 5 can, however, also be modified such that only one lamp 18 lights up in a first switching position, that a certain combination of two different lamps lights up in a second switching position as well as in a third switching position, and that all three in a fourth switching position Lamps 18 are switched on. This makes it possible, for example, to provide additional information using appropriate color codes.
