A device as claimed in claim 22characterised in that said second resilient counter-element 10 has a substantially laminar conformation and is provided with a slide surface 10 b contiguous to the respective contact surface 10 a ; said slide surface 10 b being set to abut onto the conductive element during movement of the second element 10 from the respective constraint position to the opened position to enable passage of the conductive element into the holding space Therefore, the holding space 13 set to receive a conductive element of given sizes is not able to receive conductive elements of different sizes or shapes that can be energised.
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. Each aperture 6 is suitably arranged and shaped for receiving an electric contact 7.
Operation of the lamp holding device 1 in accordance with the invention described above mainly as regards structure, is as follows. Still more particularly, as shown in FIG. Generally, each connection element has a substantially parallelepiped conformation with a square cross-section, in which four faces are defined at least one of which is arranged to be associated with a respective electric contact of the lamp holding device.
Within the scope of this technical task it is an important aim of the invention to devise a lamp holding device, in particular for lamps identified by the abbreviation PGJ5 having a rated voltage of V and an impulse voltage of V, capable of ensuring a steady electric contact between the lamp and the electric contacts even in the event of slight movements of the whole device.
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.
It is to be pointed out that advantageously the hooking means 16 can be associated with the device 1 also in the condition showing the hollow element 4 inserted into the housing space 15 of the supporting element The holding device 1 comprises a hollow body 4 which is electrically insulated and is set to receive the end portion 3 of lamp 2.
During this rotation each conductive element causes abutment of two side walls perpendicular to each other onto the slide surfaces 9 b10 b of the resilient counter-elements 9 Description of a preferred but not exclusive embodiment of a device in accordance with the invention is now given hereinafter and illustrated in the accompanying drawings, in which:.
Following a rotation of lamp 2 around its longitudinal axis, the conductive element is brought towards the first and second resilient elements 910 and abuts against the slide surfaces 9 a10 a thereof. It is to be pointed out that the present invention has been conceived in relation to lamps 2 of a new conception with a connection or base identified by the abbreviation PGJ5 having a rated voltage of V and an impulse voltage of V.

Incandescent and LED light bulbs and methods and devices for converting between em lighting products and low-power lighting products. The technical task mentioned and the aims specified are substantially achieved by a lamp holding device of the type comprising the features described in the appended claims.
A device as claimed in claim 16 dolosio, wherein the hollow body 4 has a through slot 5 formed therein and set to coloio the end portion 3 of the lamp 2. In addition, by arranging two resilient counter-elements 910 at right angles to each other, the conductive element of the lamp keeps locked within the holding space A further advantage resides in that the electric contacts are only compatible with conductive elements of a predetermined size.
Finally, it is a further aim of the present invention to make available a lamp holding device adapted for coupling with a respective frame without damaging the structure thereof. As above said, the device 1 further has hooking means 16 to secure the supporting element 14 to a frame, a ceiling light or any emmc support.
A device as claimed in claim 22characterised in that said first resilient counter-element 9 has a substantially laminar conformation and is 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 In this manner when the lamp is inserted into the bore, the lamp is rotated around its longitudinal axis in such a manner that its end portions are disposed in correspondence with two electric contacts bayonet coupling.
Alternatively, cables A can be disposed on opposite sides of the device, as shown in FIG. Also in the described solution in which the electric contacts consist of a flat spring, an unintentional slight movement of the lamp can cause separation of the connection elements from the electric contacts, which will bring about lack of distribution of electric energy.
In more detail, shown in FIG.

The bulb 2 a has a substantially elongated conformation and extends along a respective longitudinal axis. Ascendo Lighting was established in Sydney Two diametrically opposite apertures 6 are formed at the inner surface 4 b of the body 4each of said apertures being disposed in side by side relationship with a side portion 5 b of the slot 5 see in particular FIG.
There is also an important aesthetic improvement of the whole device concealing the screws under the outer surface 14 b of the supporting element 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.
The above described known art however has some important drawbacks. Advantageously, the junction element 17 b has at least one projecting portion 8 facing the supporting element and adapted to be inserted into a suitable opening 19 formed in the outer surface 14 b see in particular FIG.

To facilitate mounting operations of the device, the screws are inserted from the bulb portion of the coloio so as to arrange the respective head towards the outside of the ceramic body. Drawing from 20 years of industry experience, we have access colowio a wide network of quality suppliers and sophisticated in-house design capabilities for luminaire and lighting design. In this case, when the lamp is rotated about its longitudinal axis the connection element abuts against the spring which is coloso in a compressed state.
In addition, the 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 colodio has started rotation and not with the lamp insertion alone. A lamp holding device comprising at least: In this way the resilient elements 910 take their respective opened positions letting the conductive element enter the holding space In particular, the connection elements extend opposite each other and transversely to the longitudinal extension of the lamp.
In particular, each electric contact 7 comprises a first and a second resilient counter-element 910 both movable between an opened position to enable passage of the respective conductive element and a oclosio position to lock said conductive element.

It is in fact to be noted that an electric connection is defined through coupling of a face of each connection element with a respective flat surface of the electric contact. In more detail, the slot 5 consists of a central hole 5 a and two side portions 5 b disposed on opposite sides of the central hole 5 a and adapted to enable passage of the conductive elements of the end portion 3.
colosoo Each resilient counter-element has a contact surface 9 a10 a adapted to abut onto a respective side wall of the conductive element. Firstly, lamp 2 is associated with the hollow element 4. First of all, the device enables the conductive elements of the lamp 2 to be steadily secured to the electric contacts 7.
