Description

Modular Light System
Introduction
The present invention relates to a module for use in a lighting system. More particularly, a module is described which, together with light units, constitutes a flexible light system that can be equipped with a desired number of high-power lamps, and which can be produced in different lengths to suit requirements. The module also has means for conducting heat away from the lamps.
The module can be attached to a mounting in the ceiling or a wall, or to a free- standing mounting, and can thus be used as a light source in all known areas where lighting is necessary or desirable.
Prior art
At the heart of the present invention is a module for use in a light system, which module has several purposes.
Firstly, it should be capable of supporting inserted light units, and secondly, it should be able to conduct heat away from inserted light units.
Today there are a number of systems that employ modules in the construction of a light system. FR-2691785 discloses an example of a light system which, inter alia, consists of a module that is to be fastened to ceiling panels. The module is intended to be used with fluorescent tubes, and their number and location can be varied.
However, the system is not suitable for high-output lamps which generate a great deal of heat, and it also has a limited area of usage. The present invention is primarily intended to be used with high-output lamps and is well suited to conduct heat away from inserted lamps.
The system is simple and compact inasmuch as the main part consists of an extruded module which can be inserted onto a mounting rail wherever lighting is desirable. The module has means for receiving and supporting a desired number of light units.
Furthermore, the module has on its upper side cooling elements, preferably in the form of cooling ribs, for conducting heat away from inserted light units. A light system that is built up of modules according to the invention will be low in weight, it is flexible, cost-efficient and can be used in many areas. Summary of the invention
The object of the present invention is to provide a flexible lighting system which can be used in different areas both outdoors and indoors.
The lighting system is formed of a module which is designed to be capable of receiving and supporting one or more light source units, and wherein the module is characterised in that on one side thereof it has one or more sets of insertion grooves for the insertion and support of light source units, and that on the other side thereof it has a cooling device or devices, preferably in the form of cooling ribs, and mounting grooves for insertion of the module onto a mounting rail.
The invention also comprises a method of making a flexible lighting system to illuminate an area, wherein one or more modules are produced in a desired length, and wherein one or more light source units comprising PCB(s) with attached lamps and electronics are slid into the insertion grooves, and furthermore wherein the module(s) is/are slid onto a mounting rail which by means of its suspension point is attached to a device in the area that is to be illuminated.
The invention is further described in the accompanying set of claims.
Detailed description
The invention will now be described in more detail with reference to Figures 1-4.
The figures show preferred embodiments of the module which are not to be regarded as limiting the invention to the illustrated embodiment. The figures show different aspects of the module which forms a part of a light system, wherein:
Figure 1 is a sectional view of an example of a module;
Figure 2 is a sectional view of a slightly differently configured module with inserted light source units; Figure 3 is a sectional view of the module in Figure 2 with inserted protective casing and cover; and
Figure 4 shows a complete lighting system where the module in Figure 2 is attached to a mounting rail.
Figure 1 is a sectional view of an example of a module 10 which forms a part of a lighting system.
Figure 2 is a sectional view corresponding to that shown in Figure 1 with inserted light source units in a slightly differently configured module to show that it is not the detailed design of the module that is the main object of the invention, but the functions of the module when it forms a part of a light system.
The invention will now be described in more detail with reference to both Figures 1 and 2. On one side thereof, the module 10 is equipped with insertion grooves 25 to be able to receive and support one or more light source units 100. The module is preferably made in one piece by extrusion, but may also be made using other production techniques and in different lengths to suit requirements.
The insertion grooves 25 are formed of one or more sets of slots, and are made so that it is easy to insert a light source unit 100. The module may have multiple sets of slots to be able to support multiple light source units 100.
After a light source unit 100 has been inserted, the function of the slots is to support the light source unit 100, so that it is properly secured to the module 10.
A light source unit 100 preferably comprises a PCB 125 (Printed Circuit Board) with attached lamps and associated electronics. The PCBs 125 are adapted in length so that they fit into a module 10, and the lamps can be mounted in rows, in groups of, for example, four lamps, with any associated electronics. In a preferred embodiment, the PCBs are perforated between the lamps so that the PCB can be split along the perforation. It will then be simple to divide a PCB up into the desired length for adaptation to a light system of a certain length. On each side of the perforations there may soldering lugs or similar fastening means for attaching wires connected to components and lamps. If it is desirable to have a smaller quantity of light, a number of inserted PCBs 125 in a module can be placed at a desired distance and be connected to each other, for example, by means of lengths of wire or the like. It is also possible to limit the number of inserted units as required, i.e., not put in all the light source units 100 as shown in Figure 2.
The module 10 in its simplest form may consist solely of a horizontal central element 15. However, in a preferred embodiment, the module 10 comprises two side elements 20 that are angled relative to the horizontal central element 15. This causes a lighting system with inserted light source units 100 in horizontal central element 15 and side elements 20 to diffuse the light to a greater extent than if light source units had only been inserted in the horizontal central element. In that case, diffusing lenses, which attenuate the intensity of the light, would have had to be used to diffuse the light to the same extent. On its other side, the module 10 has cooling device(s) 30, preferably in the form of cooling ribs 35, and mounting grooves 40 for insertion of the module 10 onto a mounting rail 140. The cooling device may also be in the form of nanocoolers or a combination of different cooling techniques. High-output lamps generate heat and this will be efficiently conducted away from the light source units 100 by the cooling device(s) 30.
As mentioned, it is, in one embodiment preferable to use cooling ribs 35. Alternatively, the cooling device 30 may be formed in that the material above inserted light units 100 has a thicker wall thickness which is suitable for cooling inserted light source units 100. The material of which the cooling device 30 is made is any material that is suitable for cooling, and which at the same time is strong enough to be able to support inserted light units 100.
The function of mounting grooves 40 is to allow the module 10 to be slid onto a mounting rail.
Figure 3 is a sectional view of a module 10 with inserted protective casing 150 and cover 170. On the same side as the cooling device 30, preferably cooling ribs 35, there is one or more protective casing grooves 50 to enable a protective casing 150 to be inserted and held. When the protective casing 150 is inserted into the protective casing groove(s) 50, it will be positioned over the cooling ribs 30 and protect them.
The module 10, in a preferred embodiment, also has cover grooves 70 for mounting a cover 170 in order to protect inserted light source unit(s) 100.
Figure 4 shows a complete light system where the module 10 is attached to a mounting rail 140 which in turn, via its suspension point 180, is fastened to a device in the area that is to be illuminated. The figure shows the protective casing 150 and mounted end pieces 160 which protect the light system from moisture and penetration of dust.
By assembling the different parts described above, it is possible to produce a flexible and cost-efficient lighting system.
A module 10 may have a length of several metres and be cut to a desired length. Furthermore, one or more light source units 100 of suitable length can be slid into the insertion grooves 25.
To obtain a more robust system, a protective casing 150 can be slid into protective casing grooves 50 on the module 10 in order to protect the cooling device 30. End pieces 160 may also be secured to the end piece groove 60 to protect inserted light source unit(s) 100. Lastly, a cover 170 may be secured to cover grooves 70 in order to protect inserted light source unit(s) 100.
The module may be slid onto a mounting rail 140 which by means of its suspension point 180 is secured to a device in an area that is to be illuminated. A flexible and cost-efficient light system has then been obtained.
If desirable, several modules can be slid onto the same mounting rail A fully mounted lighting system according to the invention is scalable in a number of ways. The number of light source units 100 and their length can be decided and mounted according to need.
A lighting system according to the invention is very useful in all areas where a form of lighting is necessary or desirable. It may be anything from office, street and tunnel lighting to decorative lighting, or lighting wherever there is a need or desire therefor.
The above description discloses a preferred embodiment of a module 10 according to the invention. It will be obvious to those of skill in the art to arrive at different designs of a module and a lighting system that are within the definition provided by the attached set of claims.
