Description

Attachment arrangement and illumination system Technical area This invention concerns an attachment arrangement intended to be used to hold together an illumination system that comprises parts that in turn comprise at least one of lenses, lamps and anti-glare protection. The invention concerns also an illumination system that comprises such an attachment arrangement. Background
Various illumination systems that comprise several parts that are assembled together to a single unit where the parts in turn comprise at least one of lenses, lamps and anti-glare protection are previously known. It is difficult to assemble such a system with several parts such that all parts and their functions are located correctly relative to each other such that the distribution of light and other functions that are desired are obtained.
Such systems are normally screwed together with various arrangements or fixtures, for example various types of screw joint, and this leads to even more parts that must be kept track of and that make the work of assembly more difficult. Furthermore, tools are needed, and these must be used and checked, and this makes the work of assembly even more difficult.
Description of the invention
One purpose of this invention is to offer an attachment arrangement that makes it possible to assemble a system that comprises at least one of lenses, lamps and anti-glare protection such that all parts are correctly placed relative to each other in a simple manner and to offer a system comprising at least one of lenses, lamps and anti-glare protection and such an attachment arrangement.
This purpose is achieved with the aid of an attachment arrangement according to claim 1 and an illumination system according to claim 11.
Brief description of drawings Figure 1 shows an exploded view of an illumination system according to the invention.
Figure 2 shows a section through an exploded view of an illumination system and attachment arrangements according to the invention.
Figure 3 shows a section through an assembled illumination system and attachment arrangements according to the invention.
Detailed description of embodiments This invention concerns an attachment arrangement 1 or 2 intended to be used to hold together an illumination system 3 that comprises parts 4-6 that in turn comprise at least one of lenses 7a, lamps 7b and anti-glare protection 8.
Each attachment arrangement 1 and 2 comprises a first attachment arrangement part 9 or 10 and a second attachment arrangement part 11 and 12. Each attachment arrangement part 9- 12 is arranged at, or constitutes a part of, an illumination system part 4-6, which parts are to be assembled and retained in place against each other. The two attachment arrangement parts 9-12, when the attachment arrangement 1 or 2 is in its working position, interact with each other such that the relevant illumination system parts are assembled pairwise against each other between the illumination system parts 4-6 and are retained against each other.
The use of an attachment arrangement 1 or 2 with this design makes it possible to assemble the illumination system 3 and its component parts 4-6, comprising at least one of lenses 7a, lamps 7b and anti-glare protection 8, such that all the parts 4-6 and their functional components 7a-8 are correctly located relative to each other in a well-defined manner that locks the positions and seals the system such that particles cannot enter.
Since the two attachment arrangements 1 and 2 are in direct interaction with each other without the use of further arrangements or fixtures, the assembly of the illumination system parts 4-6 that are to be assembled and to be retained against each other and to form an illumination system 3 takes place in a simple and easy manner, and without tools.
The first attachment arrangement part 9 or 10 comprises a base 9a or 10a and a protruding part 9b or 10b that protrudes out towards the second attachment arrangement part 11 or 12.
The protruding part 9b or 10b is springing, resilient, in its attachment to the base 9a or 10a. The protruding part 9b or 10b comprises at its outer end 9c or 10c a head 9d or 10d that protrudes radially from the protruding part 9b or 10b and that comprises a first surface 9e or 10e that has an angle a1 or a2 relative to the longitudinal direction L9 or L10 of the protruding part and that is directed obliquely forwards towards the outer end 9c or 10c of the protruding part.
The first attachment arrangement part 9 or 10 comprises also a stop surface 9f or 10f with an extent U1 or U2 that is essentially perpendicular to the longitudinal direction L9 or L10 of the protruding part. The second attachment arrangement part 1 1 or 12 comprises a formation 1 1a or 12a intended to interact with the first attachment arrangement part 9 or 10 when the attachment arrangement 1 or 2 is in its working position.
The formation 1 1a or 12a comes into contact with the outer end 9c or 10c of the protruding part, against the first surface 9e or 10e. When the illumination system parts 4-6 are moved, or pressed, closer to each other, the protruding part 9c or 10c is pressed in a sideways direction somewhat outwards when the first surface 9e or 10e slides against the formation 1 1a or 12a such that the first and the second attachment arrangement parts 9-11 can take up a position in which the second attachment arrangement part 11 or 12, the formation 1 1a or 12a, comes into an interacting position with the first attachment arrangement part 9 or 10, into a retaining interaction that locks the parts.
The second attachment arrangement part 11 or 12 comprises also a counter-contact surface 11 b or 12b that is arranged to be essentially perpendicular to the longitudinal direction L9 or L10 of the protruding part and that, when the protruding part 9b or 10b of the first attachment arrangement springs back when the formation 11a or 12a has taken up its position in which the formation 1 1a or 12a comes into an interacting position with the first attachment arrangement part 9 or 10, will come into contact with the stop surface 9f or 10f of the first attachment arrangement part, whereby the first attachment arrangement part 9 or 10 will have its position locked relative to the second attachment arrangement part 1 1 or 12 and the illumination system parts 4-6 will be assembled against each other and will be retained against each other in a well-defined manner that locks the positions and that seals the system. The springing, resilient, protruding part 9b or 10b of the first attachment arrangement part that is caused to interact with the second formation 11a or 12a of the second attachment arrangement part results in that, when the attachment arrangement parts 4-6 are moved towards each other, at least one of the attachment arrangements 1 or 2 will be brought into a working position, the two attachment arrangement parts will slide against each other and will finally reach a position in which they come into contact with each other and in direct interaction with each other, to a locked position, such that the illumination system parts 4-6 will come into contact with each other, be assembled against each other and retained against each other in a well-defined manner that locks the positions and seals the system.
The attachment arrangement 1 , the protruding part 9b, the head 9d, of the first attachment arrangement part comprises a second surface 9g that is essentially directed towards the base 9a of the first attachment arrangement and that is angled at an angle crt relative to the longitudinal direction L9 of the protruding part.
The formation 11a of the second attachment arrangement is a penetrating hole 11a passing through a body 11c, and the hole 11a has a longitudinal direction L11a that essentially coincides with the longitudinal direction L9 of the protruding part 9b of the first attachment arrangement part and that is intended for the reception and housing of the protruding part 9b of the first attachment arrangement part.
The hole 11a comprises a first hole opening 11d located in a direction towards the first attachment arrangement part 9, and a first hole edge 11e that, when the protruding part 9b of the first attachment arrangement part is introduced into the hole 11a, comes into contact with the head 9d of the protruding part, against the first surface 9e. During the introduction of the protruding part 9b into the hole 11a, the protruding part 9b is pressed in a sideways direction somewhat inwards, in towards the centre of the hole, when the first surface 9e slides against the hole edge 11e, such that the head 9d of the protruding part can be introduced into and through the hole 11a.
The hole 11a comprises also a second hole opening 11f in the second end of the hole 11a and a hole edge 11 g that, when the protruding part 9b, the head 9d, has passed through the hole 11a, will make possible secure displacement, return spring motion, of the protruding part 9b by making possible a controlled slide of the second surface 9g of the head towards the second hole edge 11g, such that the head 9d of the protruding part is placed outside of the hole 11a and essentially the remainder of the protruding part 9b is placed in contact with the inner surface 11 h of the hole.
This sliding of the active parts relative to each other, and the control of the various parts relative to each other, mean that the illumination system parts will achieve perfect location and motion relative to each other. The assembly can be carried out with a simple operation and the parts of the attachment arrangement cannot be placed into anything other than perfect and exact positions relative to each other, which makes possible a simple, secure and exact assembly in which the component parts interact and are not subject to wear, load or rotation.
The attachment arrangement 1 has such a design that the length 9L of the protruding part of the first attachment arrangement part, between the second surface 9g of the head and the stop surface 9f, corresponds to the length 11aL of the hole, the thickness T of the body 11c of the second attachment arrangement part next to the hole 11 a.
These length relationships give a precise and locked location of the first attachment arrangement part 9 and the protruding part 9b relative to the second attachment arrangement part 11 , the hole 11a, when they are located in their interacting mode that also locks the positions.
The stop surface 9f of the first attachment arrangement part is a surface of the illumination system part 4 on which the first attachment arrangement part 9 is arranged or of which it constitutes a part and where the counter-contact surface 11b of the second attachment arrangement part is a surface on the illumination system part 5 on which the second attachment arrangement part 11 is arranged or of which it constitutes a part.
The fact that these surfaces, the stop surface 9f and the counter-contact surface 11 b, come into contact with each other stabilises the complete attachment arrangement 1 , in particular its component first attachment arrangement part 9 and second attachment arrangement part 11 in combination with each other, and also the illumination system parts 4 and 5, and thus the complete illumination system 3.
The first attachment arrangement part 9 is arranged at the lens part 4 of the illumination system and the second attachment arrangement part 11 is arranged at the lamp part 5 of the illumination system.
At least one of the first attachment arrangement part 9 and the second attachment arrangement part 11 is comprised in an assembly arrangement 13, which is mounted in a manner that allows it to be removed at an illumination system part 4-6. The construction of at least one attachment arrangement part 9 or 11 of the attachment arrangement 1 as a separate unit, a separate assembly arrangement 13, that is mounted at a illumination system part 4-6 in a manner that allows it to be removed makes it possible to construct complicated designs of both the attachment arrangement 9 or 11 and the illumination system part 4-6 in separate steps, before they are united to a single unit that further constitutes a part of an illumination system 3. The illumination system parts 4-6, on the occasion on which the parts 4-6 are to be assembled, comprise the important functional parts of the attachment arrangements 1 or 2, or the parts 1 and 2, such that the assembly of the illumination system 3 can take place with simple operations.
The first attachment arrangement part 9 constitutes a fixed part of the lens part 4 of the illumination system and where the second attachment arrangement part 11 is comprised in an assembly arrangement 13, which is mounted in a manner that allows it to be removed at the lamp part 5 of the illumination system.
The illumination system parts 4-6 have the form of discs and are circular, and the assembly arrangement 13 is circular and mounted at an upper edge 14 of an illumination system part with the aid of fixtures 15. The attachment arrangement 2 and its first attachment arrangement part 10 comprise an indentation 10g on the inner surface 10h of the protruding part. The formation 12a of the second attachment arrangement part is a protruding segment 12a that, when the illumination system parts 4-6 are brought against each other, comes into contact with the outer end 10c of the first attachment arrangement, of the protruding part, against the first surface 10e. When the illumination system parts 4-6 continue to be moved towards each other, the protruding part 10b is pressed in a sideways direction somewhat outwards, when the first surface 10e slides against the protruding segment 12a such that the protruding segment 12a can be introduced into the indentation 12b of the first attachment arrangement part. This sliding of the active parts relative to each other, and the control of the various parts relative to each other, mean that the illumination system parts will achieve perfect location and motion relative to each other. The assembly can be carried out in a simple operation and the parts of the attachment arrangement cannot be placed into anything other than perfect and exact positions relative to each other, which makes possible a secure and exact assembly in which the component parts interact and are not subject to wear, load or rotation. The attachment arrangement 2 and the first attachment arrangement part 10 are arranged at the anti-glare protection 8 of the illumination system and the second attachment arrangement part 12 is arranged at the lens part 4 of the illumination system. At least one of the first attachment arrangement part 10 and the second attachment arrangement part 12 is comprised in an assembly arrangement 13, which is mounted in a manner that allows it to be removed at an illumination system part 4-6. The construction of at least one attachment arrangement part 10 or 12 of the attachment arrangement 2 as a separate unit, a separate assembly arrangement 13, that is mounted at an illumination system part 4-6 in a manner that allows it to be removed makes it possible to construct complicated designs of both the attachment arrangement 10 or 12 and the illumination system part 4-6 in separate steps, before they are united to a single unit that further constitutes a part 4-6 of an illumination system 3. The illumination system parts 4-6, on the occasion on which the parts 4-6 are to be assembled, comprise the important functional parts of the attachment arrangements 1 or 2, or the parts 1 and 2, such that the assembly of the illumination system 3 can take place with simple operations.
The attachment arrangements 1 and 2 can be brought into a non-locking condition by the spring-loaded protruding parts 9b or 10b of the first attachment arrangement parts 9 and 10 being brought out of their locking interaction with the formation 11a of the second attachment arrangement part through being again sprung inwards or outwards, whereby the illumination system parts 4-6, 4 and 5 or 4 and 6, can be drawn in a direction away from each other. The attachment arrangements 1 and 2 constitute snap-activated locks with different interacting parts that facilitate and make easier not only the assembly but also the disassembly of an illumination system 3.
The invention concerns also an illumination system 3 that comprises at least two or, alternatively, three parts 4-6 that in turn comprise at least one of lenses 7a, lamps 7b and anti-glare protection 8, where the illumination system parts 4-6 are assembled and retained against each other with the aid of a number of attachment arrangements 1 and 2, or 1 or 2, of the type that has been described above.
The attachment arrangements 1 and 2, or 1 or 2, are located around and outwards from the opposing surfaces, the upper edge parts, the upper edges, of the illumination system parts 4- 6 that are to be assembled together, in a direction away from one of the illumination system parts towards the second illumination system part. At least two attachment arrangements 1 and 2, or 1 or 2, according to the invention are active between two illumination system parts 4-6. The two attachment arrangements 1 or 2 ensure a correct placement and correct locking in place of at least two illumination system parts 4 and 5 or 4 and 6, and they minimise the risk of faulty placement and material rotation in association with the work of bringing the attachment arrangements 1 and 2, or 1 or 2, into their working positions.
It may also be the case that at least three attachment arrangements 1 and 2, or 1 or 2, are active between two illumination system parts 4-6. The provision of at least two attachment arrangements makes it possible to stabilise also the two illumination system parts 4 and 5 or 4 and 6 relative to and against each other such that they do not rock back and forth and make the work of bringing the attachment arrangements 1 and 2, or 1 or 2, into their working positions more difficult. A somewhat irregular location of the attachment arrangements 1 or 2 around the outer part of the illumination system parts 4-6 further ensures that the illumination system parts 4-6 achieve the correct positions relative to each other when they are to be assembled, in association with the work of bringing the attachment arrangements 1 and 2, or 1 or 2, into their working positions.
The illumination system 3 comprises a lens part 4 that comprises a holder 4a designed for the reception of a specified number of lenses 7a that are mounted at this holder 4a.
The illumination system 3 comprises a lamp part 5 that comprises a lamp-supporting circuit board on a metallic base material 16, metal-cored printed circuit boards, MCPCB, and the lamps 7b are LED lamps.
The lens part 4 of the illumination system comprises, is provided with, constitutes, not only the first part 9 of an attachment arrangement but also the second part 12 of an attachment arrangement, and it constitutes in this way an intermediate part in the illumination system 3 in the case in which the illumination system 3 comprises all three illumination system parts 4-6 and thus comprises lenses 7a, lamps 7b and anti-glare protection 8.
Parts and fittings may be freely combined within the innovative concept of the invention, as long as their design and function are exploited in the manners described.
