Definitions

  • the present invention refers to a device for the power supply of fluorescent discharge lamps, by means of which a new and profitable effect is achieved for the power supply of fluorescent lamps.
  • the device of the present invention is destined to solve a problem that presently occurs in fluorescent lamp illumination systems, namely the relatively frequent failure of the fluorescent lamps due to the extinguishment of its active life or due to other causes. When this occurs the lamp fails, many times quite suddenly, ceasing to fulfil its function.
  • fluorescent lamps are relatively complex in their handling and are installed in high locations of the areas to be illuminated, their replacement cannot be performed in an easy and practical manner as is the case with a light bulb, so that when a fluorescent lamp stops working it causes problems and inconvenience until it is replaced, a task that in most cases requires trained staff and a ladder, etc.
  • the present invention is destined to solve these inconveniences allowing lighting installations in which, for each fluorescent tube, another reserved tube or several others are available, being the system of the following invention arranged in a way that only the normal lighting of one lamp takes place, but in case of its failure, automatically, another one of the reserve lamps will light up until the total extinguishment of all the reserve lamps installed takes place.
  • This allows to achieve lighting installations that offer noticeably regular illumination and which rarely stop performing as desired since when a reserve tube begins to operate there will be time enough to replace it, which allows proper maintenance of the light conditions of the particular area illuminated by fluorescent lamps.
  • the present invention will be applicable domestically as well as in offices, warehouses etc., given that in all cases the same advantage will be obtained, namely that of achieving a more reliable illumination of the desired area and allowing the replacement of lamps when desired, for example during periodic inspections of the light installation which will no longer be direct consequence as it occurs nowadays, of the partial or total lack of illumination of the area due to the failure of one or several lamps.
  • U.S. Patent no.4 862 037 discloses and automatic relamping system for lamps with different starting voltages with an starting circuit including an oscilator, an output capacitor, a step-up transformer with the output capacity connected in parallel and a second capacitor coupled in series between the output capacitor and the lamps.
  • JP-A-03171605 discloses a stabilizer for discharge lamp composed of a core and a coil wound around the core and arranged in the center of a case, with two capacitor units and an insulating resin filled up in the closed space.
  • the present invention foresees the arrangement of a single balast supplying power in parallel to several identical fluorescent lamps of the same lighting system, being the power characteristics of the balast those required for a single lamp , which means that in activating the system only a single tube will illuminate, and when this tube ceases to function for whatever reason, in a very short period of time, which could be less than 0.2 seconds, another one of the reserve lamps will light up and so on. Therefore the device of the invention will allow the sequential power supply of fluorescent lamps in the same lighting installation without the absence of light ever being noticeable due to the failure of one lamp.
  • the single balast used in the device of this invention possesses a specific characteristic by which the exit of the conducting cables from the inside of the balast takes place through a single body of insulating resin in which the components of the balast and the wire connections are monolithically embedded without any exposed connection devices, which confers the balast more solidity, simplifies its manufacturing process and provides it with a much higher resistance to any kind of external agents.
  • the device object of the present invention is based fundamentally in the disposition of a single balast 1, Figure 4, with appropriate characteristics to feed only one tube of one array of various identical tubes, as shown with reference numerals 2 and 3, being the total number of lights in a set absolutely variable.
  • These fluorescent lamps are connected in parallel with respect to the single balast 1.
  • the balast will remain connected by means of wires 4 and 5 to one polarity and the neutral of the AC current source, showing as well the proper grounding 6.
  • the fluorescent lamps 2 and 3 will be connected in parallel with the conductor pairs 7 and 8 for lamp 2 , and 9 and 10 for lamp 3.
  • the balast will contain the components shown in figure 5, in which elements 11, 12, 13, 14, 15 and 16 have been represented as blocks integrated inside a monolithic block of insulating resins 17, inside which remain the connections of the various conducting cables, so that the outside wall 18 of the monolithic block 17 is perforated directly by the conductors, not exposing to the exterior a single connection.
  • the wall itself 18 will come out all of the power supply cables and the wires to the multiple lamps such as 19 and 20 or a variable number of them, connected in parallel with the single balast, having the above mentioned construction.
  • Blocks 11 to 16 contain the following elements: Block 11: filters and suppressors; block 12 : rectifier and protections; block 13: corrector of power factor and potential difference elevator; block 14 : commutation and high frequency control; block 15 : lamp control and power manoeuvre; block 16 : absence detectors, potential and current.
  • Figure 3 shows the front wall 18 of the monolithic block of resins through which conductors 21, 22, 23, 24 pass to feed the two fluorescent lamps in parallel as well as conductor 25 which holds the wires to supply power and for the grounding connection.
  • the present invention allows the control of the power supply to several identical fluorescent lamps by means of a single balast suitable for one individual tube, making a connection in parallel of the various tubes with the single balast, resulting in the lighting of a single or main lamp and continuing to light one of the other tubes as they cease to be operative for whatever cause.
  • the proper device to perform the present procedure consists of a completely monolithic balast which will contain its components inside of a block of insulating resin, and in this block the connections to the wires for the connection in parallel of several identical tubes, which wires go through the wall of the monolithic block with no external connections exposed.
