Description

ILLUMINATION APPARATUS COMPRISING AN ILLUMINATION DEVICE FOR EMERGENCY OR GUIDANCE ILLUMINATION AND WHICH ALSO CAN COMPRISE AT LEAST ONE ORDINARY LIGHT FITTING
The present invention relates to an illumination apparatus comprising an illumination device for emergency or guidance illumination and which also can comprise at least one ordinary light fitting, of the type set forth in detail in the preamble of claim 1.
An emergency illumination is brought about at present in e.g. public and industrial places by providing existing light fittings with an emergency illumination assembly, usually comprising an electronic unit and a battery, which is connected between existing operating devices and an existing source of light. When the power is disconnected, the source of light is operated by the emergency illumination assembly through an automatic switching. When the power is connected again, the emergency illumination assembly will automatically switch back to the normal operation mode. The emergency illumination assemblies in previous designs normally have a capacity of 1-3 hours. The emergency illumination often is carried out with a reduced power.
Such already known apparatuses are impaired by various drawbacks. They e.g. often take up a great deal of space and their production is complicated. The obtained product often is expensive and tends to have a limited life. Many modern light fillings are small, which means, that a mounting of ordinary emergency illumination devices thereon practically is not allowed. Also, some light sources are not suitable or cannot be used respectively for emergency illumination purposes; they are e.g. discharge light sources.
The object of the present invention is to counteract and as far as possible eliminate the above-mentioned drawbacks as well as to generally further develop the state of the art in this field. This object is attained according to the invention by mainly designing an illumination apparatus of the type set forth in the introduction in accordance with what is set forth in the characterizing clause in claim 1. A device according to the invention in such an apparatus comprises a very intensive light emitting diode, which is used as a light source for e.g. emergency illumination operation. According to the invention this very efficient light diode is supplemented with a reflector, applied around the diode and designed in a special way and which is necessary , if the invention is to meet at least those requirements, which a device according to the invention is to meet. This device also comprises electronic components, which take care of the charging/moni- toring of the batteries as well as the switching from normal operation to emergency illumination operation and vice versa, as well as a group of batteries , preferably rechargeable . By means of the apparatus according to the invention several important advantages is comparison to the state of the art are attained , i.e. :
a) Improved personal safety due to the use of a separate light source with a very long life for e.g. emergency illumination operation instead of the existing light source in an ordinary light fitting ; b) Very long service intervals due to the long life of the light source and the batteries; c) Allows an emergency illumination version also on modern size-reduced light fittings, because the apparatus according to the invention and its components are considerably smaller and require considerably smaller space than the emergency illumination products known so far ; d) Allows an emergency illumination installation also when existing or newly designed light fittings do not allow an integration in the fitting itself; e) Environmental protection-techniques with considerably smaller amounts of environmental pollution-substances, since the preferably rechargeable batteries according to the invention are allowed to have a considerably smaller capacity in comparison to the state of the art ; f) Improved illumination techniques . When an emergency illumination is planned, an evenness or uniformity is required. By means of an apparatus according to the invention these and other requirements can be met, which often is not the case using the state of the art. Requirements as to evenness are specified in European standards as well as in national authoritative requirements.
The apparatus according to the invention also allows the use of it as a night illumination or a guidance illumination , the corresponding components being used, but preferably excluding several batteries and using another printed circuit.
Additional characterizing features of and the advantages of the present invention will be set forth in the following description, reference being made to the accompanying drawings, which show a few preferable but not limiting embodiments of the invention. The drawings show in detail in :

The embodiment of an illumination device according to the invention, depicted in Fig. 11a and Figs. 1-6 respectively, will be enclosed in an ordinary light fitting of any kind. The device comprises an electronic component/printed circuit 12, several batteries 7 as well as a diode holder with a very intensive light emitting diode 6, which is to be mounted in a simple way in the light fitting via a bore. A reflector 9 around the diode is designed by using a computer to be able to optimize the light yield, the light picture as well as the mechanical shield. Also, in the reflector an indicator diode 13 is mounted , designed to indicate the condition, which results in, that the mounting in the light fitting is experienced as very discrete. This design includes also a combined charging/driver unit for said batteries, which suitably are of NiMH-type. This embodiment is preferably designed to provide emergency illumination during about 3 hours.
Also, this device is provided with an integrated self-test , which supervises electronic components and batteries. A possible found failure is indicated via the light guide 8, e.g. having a green colour. Also, it is possible to connect an external monitoring system via a potential-free contact. The batteries and the driver unit should be located in places in a light fitting, where they are not subjected to relatively high temperatures.
The use of this technique meets completely different requirements concerning the size as well as the life in comparison with what has been allowed so far. The device allows an improved personal safety, since the emergency illumination is brought about by a light source with an extremely long life, which also is not reduced, when it is used in normal operation. The risk, that the emergency illumination fails due to burnt-out illumination sources, consequently is almost non-existent.
An emergency illumination device according to the invention provides an important improvement as regards the evenness of the illumination level in comparison with conventional illumination devices. In this way it will be considerably simpler to plan the illumination of an apparatus by means of a device according to the present invention than by means of conventional solutions.
A device according to the invention allows emergency illumination versions also on light fittings, which normally cannot be equipped with emergency illumination via a centralized or a decentralized system. Instances of light fittings, which so far have not been acceptable as emergency fittings, are instances with light sources of the metal halogen or mercury type as well as fittings, which, due to their size-reduced design, have not allowed en emergency illumination function.
Of course, a device according to the invention can also be mounted in light fittings, which today already are equipped with an emergency illumination function in another way, e.g. fluorescent tube fittings, in order to replace this conventional emergency illumination function.
The embodiment shown in Fig. 1 lb and Figs. 7-10 respectively is designed as a self- contained unit, i.e. independent of the location of a light fitting. This embodiment comprises the same or similar components as the above-described embodiment. The unit is particularly adapted to be mounted in a ceiling, e.g. with rims and with decoration and directly against the ceiling boxes, frequently used or retractable in false ceilings, cabinets, cornices etc. The unit is provided with four lead-in holes and can, in addition to being connected straight from above, be energized via an outer cable. It is also possible to use a transmission through 1,5 mm 2-conductors. This embodiment is used principally , when light fittings do not allow the integration of the first-described embodiment or in case it is desirable to be able to use a system independently of the light fitting choices. This embodiment can be used in a advantageous way in such premises, which have no ceiling illumination or in which the existing fittings ought to be kept.
This separate embodiment has been developed in order to provide a simple maintenance. The electronic component or the battery can as required be replaced without affecting the fixed installation. Also, all the live parts are protected, also when the electronic part/battery have been removed, which means, that the voltage up to the unit does not have to be de-energized during maintenance. Thus, during service the entire lower half of the device can be directly exchanged for a new one, which means, that the safety level does not deteriorate during a maintenance.
A few technical data for the two embodiments : The light emitting diode suitably is of the high power type, white, 1 W. The charging and functioning indication is done by means of a green light emitting diode. Power : 3 poles (fixed phase, zero, protective earth). The fixed phase must be directly connected to a group fuse. One version of a certain self-test system also has a connection for a starting phase. Monitoring : 2 poles (max. 24 V / 50 mA). All the connections can be transition connected 2 x 1,5 mm 2. Batteries : 3 cell NiMH, life at least 4 years. Self-test : integrated with the possibility to connect an external monitoring system.
A device according to the invention is as a standard provided with an integrated self- test system, which e.g. every two hours controls the charging function , the battery capacity and that the light emitting diode is not defect. During the control itself a very brief flash (e.g. 19 ms) can be perceived at the light emitting diode. During the controls possibly detected errors are indicated via various signals through the indication diode. A blinking indication diode indicates a defect or not connected light emergency diode. A turned out indication diode indicates a defect battery or electronic unit. The electrical potential contact on the unit is opened up.
A device according to the invention is provided with a potential-free contact 23, to which an external emergency or monitoring system can be connected. The control is, when no errors are indicated , normally connected (NC) and is able to maintain 24 V / 0,05 A. When an error indication arises, the contact is opened up. The coil suitably is connected in series between the various units and should be limited to only include the units in one space. In this way it is indicated, in which space there are errors in any of the units. Via the indication diode the defect unit can then be visually identified in a simple way. The potential-free contact can also be used to be connected to a BMS-system (Building Management System) , type LON or EIB. However, a connection to such systems requires a separate node.
According to a further development of the above-described self-test system a monthly and yearly control of the emergency operation time can also be performed. The system is designed to be able to automatically carry out the following controls : 24 h after the starting of an apparatus according to the invention a control is carried out during 2/3 of the specified emergency operation time , i.e. the device according to the invention passes into the emergency illumination position during two hours. Each month the emergency illumination function is controlled during 10 s. Every 12 months the emergency illumination function is controlled during 2/3 of the specified emergency illumination time, i.e. the device according to the invention passes into the emergency illumination position during two hours. Possible errors discovered during the controls are indicated via various signals by means of the indication diode and via the potential-free contact in conformity with the first described embodiment .
The self-test system described now allows also a monitoring during an optimal time during a twenty-four hour-period in order to carry out the automatic controls. Such a monitoring may be suitable especially in environments, in which the emergency illumination apparatus must not enter a test phase, e.g. in movie theatres, when the light is out. Via a connection to a lighting phase from the existing illumination apparatus it is possible to prevent, that the controls are carried out , when the premises are used (the illumination functioning). In case the firing voltage is disconnected, the control is carried out according to the built-in calendar in the unit. The same is true, in case no firing voltage is connected. The unit then takes care of itself automatically.
In the drawings Figs. 11a and l ib respectively show an illumination apparatus according to the invention in its entirety. This includes one or several ordinary light fittings 2, an illumination device 3 and 5 respectively according to the invention, an emergency illumination assembly 4, which is a component in the illumination device and belongs to it, a light emitting diode 6, one or several batteries 7, a light guide 8, a reflector 9, compensate springs 10, mounting tongues 11, a printed circuit 12, an indicator diode 13, a light guide mounting leg 14, a contact element 15, a power separator 16, a casing 17, a decoration screen 18, a connection unit 19, a printed circuit contact 20 to emergency illumination assembly 4, a covering plate 22, an external alarm contact 23 and a power supply 24.
The invention is not limited to what has been described above and to what has been shown in the accompanying drawings, but the invention can be modified and supplemented in an arbitrary manner within the scope of protection for the inventive idea and according to the following claims.
