A device as claimed in claim 16wherein the hollow body 4 has a through slot 5 formed therein and oclosio to receive the end portion e,c of the lamp 2. Furthermore, the supporting element 14 made of insulating material which is in contact with the screw heads 17 a enables better insulation of the energised parts. Under this situation, the screw head being is disposed externally and in sight could be dangerously energised.
Whether your lighting needs require a custom build or off-the-shelf solutions, we provide the best of both worlds. In addition, due the presence of a crack in the ceramic body no electric insulation exists between the energised parts and the screw. Furthermore, a further drawback resides in that known devices enable insertion and energising also of lamps having operating emv different from the provided ones. 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 Advantageously, each conductive element has a parallelepiped conformation with a square cross section in which four side walls are defined.
Consequently, distribution of electric energy to the lamp 2 is always ensured. In particular, each electric contact 7 is advantageously made of metal and can be associated with a respective conductive element projecting from the end portion 3 of the lamp 2 to connect the lamp 2 to suitable electric-energy transmitting means A shown in the accompanying drawings.
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 colodio the operating features of the lamp are different from the expected ones. Drawing from 20 years of industry experience, we have access to a wide network of quality suppliers and sophisticated in-house design capabilities for luminaire and lighting design.
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 coloosio 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 lamp is maintained in contact with the upper surface 4 a of the lamp holder. With our extensive design capabilities, customers are assured that all our products meet their design intent.

Advantageously, under this situation three out of the four side walls of each conductive element are in abutment against a respective surface and the conductive element is locked by means of the thrust action of the resilient elements 9 Also known are lamp-i holding devices in which the electric contacts consist of a resilient flat spring. A device as claimed in claim 26wherein, when the lamp 2 is inserted into the through slot 5 and rotated around a longitudinal axis of the lamp, said pair of conductive elements projecting from said end portion 3 of the lamp 2 are respectively disposed in correspondence with said pair of electric contacts 7.
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 more detail, the present invention advantageously applies, as a lamp holding device, to the lamps of new conception identified by the abbreviation, which lamps have a rated voltage of V and an impulse voltage of V.
The hooking means 16 is further provided with a pair of screws 17 housed within respective cavities 18 made in the junction element 17 b.
Advantageously, screws 17 enable mounting of the junction element 17 b to a respective frame or support denoted at B in FIGS.
cooosio As better shown in FIG. 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.

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 A device as claimed in claim 32characterised in that said hooking means 16 comprises at least two through cavities 18 formed in said junction element 17 b to house two screws 17 disposed with their heads 17 a turned towards the outer surface 14 b of the supporting element Under Professional Accountants Emx Chapter 50only firms and corporate practices of 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 mec Lamp holders, generally made of an electrically insulating material, further allow assembling of same to bodies of lighting apparatus of different kinds constituting spotlights or floodlights, for example.
A further drawback relates to positioning of the seats for the hooking screws distributed in the ceramic body. 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.
The above described known art however has some important drawbacks. With reference to the drawings, the lamp holding device in accordance cllosio the invention has been generally denoted at 1. Firstly, lamp 2 is associated with the hollow element 4. The colosip 1 further comprises a supporting element 14 made of an electrically insulating material, preferably plastic material, and having a respective housing space 15 within which the above mentioned hollow body 4 is housed.
Wmc electrically insulating hollow body 49 is disposed within the housing space 15 and is set to receive an end portion 3 of a lamp 2. 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.
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 lamp has started rotation and not with the lamp insertion alone.
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. In detail, each resilient counter-element 910 consists of a thin plate such bent as to define a slide surface 9 b10 b contiguous to the respective contact surface 9 a10 a.
