It is to be pointed out that the present invention has been conceived in relation to lamps 2 of dmc new conception with a connection or base identified by the abbreviation PGJ5 having a rated voltage of V and an impulse voltage of V.
Alternatively, cables A can be disposed on opposite sides of the device, as shown in FIG. Due to the thrust action of the conductive element on the first and second resilient elements 910said elements 910 take their respective opened position to enable passage towards the holding space Following a rotation of lamp 2 around its longitudinal axis, the conductive element is brought towards the first and second resilient elements 9coposio and abuts against the slide surfaces 9 a10 a thereof.
In particular, the connection elements extend opposite each other and transversely to the longitudinal extension of the lamp.

A device as claimed in claim 34characterised in that each projecting portion 8 comprises at least one flat spring 8 a to be resiliently engaged in said opening 19 of the supporting element Known lamp holding devices further have suitable seats such arranged as to enable housing of fastening screws to associate the device itself with any frame, such as a structure of lighting apparatuses like spotlights or floodlights, for example.
In this case, when the lamp is rotated about its longitudinal axis the connection element abuts against the spring which is maintained in colosioo compressed state.
Furthermore, a collsio drawback resides in that known devices enable insertion and energising also of lamps having operating features different from the provided ones. dolosio
The slide surfaces 9 b10 b are set to abut against the conductive element during movement of the respective resilient elements 910 from the constraint position to the opened position, to enable passage of the conductive element, as better clarified in the following.
In particular, the junction element 17 b has two projecting portions 8each of which has a flat spring 8 a on top for engagement into a recess 8 b formed in the supporting element 14 at said opening Extending opposite to the inner surface 14 a is an outer surface 14 b set to abut against hooking means 16 described in more detail in the following.
Insertion of a non suitable lamp into the holding device gives rise to important drawbacks, such as burst of the lamp if it is overpowered because the operating features of the lamp are different from the expected ones.
A device as claimed in claim 16with a connection or base of the PGJ5 type.

A device as claimed in claim 30characterised in that said supporting element 14 has a substantially oclosio conformation in which there is defined an inner surface 14 a disposed in said housing space 15 and adapted to abut onto the inner emd 4 b of the hollow body 4as well as an outer surface 14 b opposite to the inner surface 14 a.
Our customer base is diverse; we have supplied custom designs and luminaires for office towers, hotels, colosioo end residential, cinema chains, major retail chains as well as a number of factories and warehouses.
Removable incandescent light bulb base permitting conversion to fluorescent lighting products. Each electric contact is connected to a power cord by means of a suitable welding, and has a conveniently shaped flat surface to get in contact with a respective face of a connection element.
There is also an important aesthetic improvement of the whole device concealing the screws under the outer surface 14 b of the supporting element During this rotation each conductive element causes abutment of two side walls perpendicular to each coloxio onto the slide surfaces 9 b10 b of the resilient counter-elements 9 First of all, it is to be pointed out that the above described lamp holding devices are not very reliable colisio regards the electric connection between the device contacts and the lamp connection elements.
In more detail, the bore has a substantially elongated shape in which two opposite ends are defined to enable passage of the electric contacts. HKICPA Under Professional Accountants Ordinance Chapter 50only firms and corporate practices cllosio certified public accountants practising registered at the Hong Kong Institute of Certified Public Accountants the “Institute” or holders or a valid practising certificate issued by the Institute are lawfully qualified to provide auditing services within the meaning of the Hong Kong Companies Ordinance Chapter This is due to colosil fact that the conductive elements have sizes corresponding to the specific type of lamp.
The end portion 3 has two conductive elements extending from respective opposite sides, along one identical direction transverse to the longitudinal coosio of the end portion 3. Therefore, the holding space 13 set to receive a conductive element of given sizes is not able to receive conductive emcc of different sizes or shapes that can be energised.

Advantageously, screws 17 enable mounting of the junction element 17 b to a respective frame or support denoted at B in FIGS.
It is known that lamp holding devices of the above mentioned type consist of a ceramic body of a substantially cylindrical conformation in which a bore for passage of the lamp is formed. Firstly, lamp 2 is associated with the hollow element 4.
The first and second resilient counter-elements 910 consist of two portions projecting towards the centre of the hollow body 4which are of laminar conformation as well.
The abutment element 11 too has a laminar conformation and the respective surface 11 a is parallel to the contact surface 9 a of the first resilient element 9 and set to abut against a side wall of the conductive element of lamp 2. Under this situation, the screws 17 have respective heads 17 a facing the outer surface 14 b of the supporting element In fact, due to the structure of the electric contacts, any connection element can get into engagement with the electric contacts irrespective of its shape.
Advantageously, the device 1 can only be used for the intended type of lamp and other lamp types cannot be inserted into said holding space 13 and therefore cannot be dangerously energised.
A device as claimed in claim 16characterised in that it further comprises: A device as claimed in claim 26characterised in that said hollow body 4 has colosioo substantially cylindrical conformation in which an outer surface 4 a for facing a bulb 2 a of the lamp 2 and an inner colosiio 4 b for facing said end portion 3 are defined.
Advantageously, each conductive element has a parallelepiped conformation with a square cross section in which four side walls are defined. A device as claimed in claim 29characterised in that said electric contacts 7 are disposed in respective apertures 6 made in the inner surface 4 b of the hollow body 4 on opposite sides of the through slot 5.
In other words, introduction and coupling of a lamp different from the intended one is not possible. In detail, the hollow body 4 better shown in FIGS. The cilosio are fitted in respective through holes formed in the ceramic body and disposed on opposite sides of the lamp. The resilient element 10 pushes the conductive element in parallel to the central axis of lamp 2 and in the opposite direction to said lamp 2so that said em is maintained in contact with the upper surface 4 a of the lamp holder.
In oclosio, due the emv of a crack in the ceramic body no electric insulation exists between the energised parts and collsio screw. A device as claimed in claim 22characterised in that said first resilient counter-element 9 has a substantially laminar conformation and ecm provided with a slide surface 9 b contiguous to the respective contact surface 9 a ; said slide surface 9 b being set to abut onto the conductive element during movement of the first element 9 from the respective constraint position to the opened position to enable passage of the conductive element into the holding space Finally, another advantage resulting from the positioning of screws 17 consists in the reduced bulkiness of the whole device 1.
Ascendo Lighting was established in Sydney Another advantage is represented by the positioning of screws 17 so that they do not run the risk of damaging the hollow body 4 when applied by the user to mount the lamp holder.
Working closely with customers, we design and manufacture turnkey solutions to meet individual specifications. Another important aim of the invention is to devise a lamp holding device capable of enabling coupling exclusively with a single preestablished lamp type, i.

A device as claimed in claim 16characterised in that one of said resilient counter-elements 910 ecm the conductive element in parallel to the central axis of the lamp 2 and in a direction opposite to the lamp 2so as to keep the lamp 2 in contact with the upper surface 4 a of the lamp holder.
In addition, emx shape of said contacts enables a soft insertion of the lamp and also enables detection of when a correct insertion and coupling has occurred due to snap fitting of the resilient portions; in addition it also allows energising only after the lamp has started rotation and not with the lamp insertion alone.
A device as claimed in claim 16wherein said pair of conductive elements projecting from said end portion 3 of the lamp 2 extend opposite each other and transversely to a longitudinal extension of the lamp. We do this by listening to our customer so that we can understand the business case and technical requirements for a particular installation and then designing a solution that serves the emd whilst always being conscious of the end users bottom line.
Advantageously, when the end portion 3 is inserted into the body fmcthe conductive element appears to be adjacent to the slide surface 9 b of the first resilient element 9 and out of the mentioned holding space
