Definitions

• the invention relates to an alarm lamp, i.e. in particular a luminaire such as that used in automatically operating systems for indicating operational disorders.
• a luminaire such as that used in automatically operating systems for indicating operational disorders.
• signal lamps are used which are switched on automatically if, for example, a malfunction or the like occurs.
• Such lamps which indicate an alarm state and which are usually accommodated in a protective container, a protective hood or the like made of transparent or translucent and generally colored material, such as glass or plastic, are intended to prevent malfunctions from a greater distance draw attention and are therefore usually in an exposed position, preferably on the housings or boxes of the switching and control devices of the systems to be monitored.
• the invention is therefore based on the object of creating an alarm lamp of the type mentioned above which, because of its arrangement and / or design, makes destruction or damage largely impossible or at least eliminates the incentive to do so.
• the lamp and associated protective hood can be guided into the operating position from a fixedly arranged protective housing, or else in that the protective housing surrounding the lamp and protective hood can be moved away, for example raised or pivoted away .
• the protective housing surrounding the lamp and protective hood it may be sufficient for the protective housing surrounding the lamp and protective hood to be at least partially movable away, for example lowerable or liftable or pivotable away.
• the housing or the control box of the switching or control device of the system to be monitored can expediently serve as the protective housing for the alarm lamp essentially formed from the lamp and the associated protective hood, in which a special chamber for accommodating the lamp can be separated by a partition, which can be raised and lowered in an opening of this chamber.
• the lamp and protective hood of the luminaire can be arranged on a common carrier and can be guided by this into the operating position as it moves from the protective point.
• the movement should be controlled by a drive that can be triggered at the same time as the alarm lamp is switched on.
• a spring can be provided in a particularly simple form as the drive means, which on the one hand expediently acts directly on the carrier and leads it from the protective position into the operating position.
• this carrier In the protective position, this carrier can be held by a disengageable locking device, for example a pawl, which can preferably be automatically disengaged at the same time as the alarm lamp is switched on.
• the movement of the lamp and protective hood or their carrier from the protective position into the operating position should be limited by a stop which becomes effective when the operating position is reached.
• the protective hood of the lamp or its support can be provided at its or its free end with a flange-like edge, which rests against the housing in the lowered protective position and seals the housing opening.
• the lamp 11 and the protective hood 12 are arranged on a common carrier 13 and can be guided together with the latter from a protective housing 15, which can be, for example, the housing or the switch box of a switching device for the automatic operation of pump systems .
• a protective housing 15 can be, for example, the housing or the switch box of a switching device for the automatic operation of pump systems .
• the opening of the protective housing 15 is closed by a cover 16 which is connected to the support 13 and projects flange-like beyond it. Lamp 11 and protective hood 12 are thus protected against damage.
• the carrier 13 ' is moved upward, so that the lamp 11 and protective hood 12 protrude from the housing 15 and are visible from all sides.
• lamp 21 and protective cover 22 are fixed in some way, for example by means of a common support 23, for example on the top of the switch box of the system.
• lamp 21 and protective hood 22 are covered by a cup-shaped protective housing 25, which in the operating position is at least raised upwards so that the light exit is not obstructed.
• lamp 31 and protective hood 32 are on a common carrier 33 arranged.
• This is stationary and, as in the principle picture according to FIG. 2, is arranged on the top of, for example, the switch box.
• the lamp 31 with protective hood 32 protruding over the housing is surrounded by a preferably cylindrical or, in cross section, tubular protective housing 35, the outer opening of which is closed by a cover 36 which, like the carrier 33, is arranged in a stationary manner.
• the protective housing only needs to be guided downwards so that the light radiation is free.
• lamp 41 and protective hood 42 are arranged on a common carrier 43.
• This carrier is pivotally arranged with a cover 46 hinged to the protective housing 45 with the aid of a hinge 44 or itself configured as a pivotable cover.
• cover 46, 43 together with the lamp 41 and its protective hood 42 need be folded out of the housing 45 into the position indicated by the arrow 47 in order to achieve an unobstructed light emission.
• Fig. 5 which the principle of F g. 1, it is assumed that the alarm light is accommodated in a chamber of the switch box 51 of the system to be monitored, which chamber is not particularly shown and which serves as a protective housing.
• This control box has an opening 511, in which the alarm light according to the invention with all its parts len receiving bowl 52 sits.
• This cup is sealed off from the housing wall 51 by a sealing ring 53.
• In the bowl 52 there is a socket 54 for an electric lamp 55.
• This socket 54 sits in a with its edge 561 on the inside of the bowl 52nd guided support plate 56.
• a spring 57 presses against the edge 561 of this support plate, which is supported with its lower end on the bottom of the cup 52.
• a cup-shaped protective hood 59 for the alarm lamp 55 is fastened by means of screws 591.
• This protective cap 59 has at its free end protruding from the cup 52 a flared edge 592 which together with the bottom of the protective cap forms a cover which covers the cup opening and, in the retracted protective position of the lamp, bears against one another Sealing ring 60 sets, which is attached to the inner circumference of the cup opening.
• This sealing ring 60 also serves as a guide for the protective hood when the protective hood is moved from the protective position shown in the drawing and inserted into the housing into the operating position indicated by broken lines.
• the spring 57 which can push the carrier 56 with the lamp 55 and the protective hood 59 upwards, serves to bring the lamp into the operating position as soon as a pawl 62 triggered by a relay 61 has been released, which the carrier plate in the holds lower position.
• On the upward movement of the carrier 56 with the lamp 55 and the protective hood 59 is limited by a stop 63 to which the carrier 56 abuts as soon as the operating position is reached.
• the protective hood 59 only needs to be pressed down by hand until the pawl 62 engages behind the carrier plate 56.
• the protective hood 59 then forms, with its flange-like edge and the base, which may be reinforced by inlays or supports and which may be painted in the color of the protective housing 51, an inconspicuous device part which is also largely secured against willful destruction .
