A LAMP FITTING

Abstract: A wall-mounted or ceiling-mounted lamp fitting includes an attachment plate (1) which is intended to be secured to an attachment surface (4), such as a ceiling or a wall surface, in the close proximity of an installation cable (3) provided with an electrical outlet (2). The attachment plate supports at least one holder (5) for a bulb (5') and the holder or holders are connected electrically to the electrical outlet on the side of the attachment plate remote from the attachment surface. The lamp fitting is mainly characterized by a reflecting device (6) which is mounted on the side of the attachment plate (1) remote from the attachment surface (4), wherein the reflecting device is located at least in the close proximity of an attachment plate part (7) which is intended to be located in the close proximity of the installation cable (3), so as to limit the temperature of the area in the near vicinity of the installation cable, when the lamp is illuminated.

Description: A Lamp Fitting Ihe present invention relates to a vall-iπouπted or c_eil_-ng-ιtιounted lamp fitting, cαrπprising an attachment plate which is intended to be secured to a ceiling sur ace or a wall surface in the vicinity of an electric current outlet, and which attachment plate carries at least one light bulb holder, said holder or holders being intended to be c_onnected electrically to said current outlet on the side of the attachment plate remote from the attachment surface. Lamp fittings, lamp suspensions, of this kind are normally intended for two light bulbs and two diametrically located bulb holders are normally provided therefor. The attachment plate is normally made of plastic. With a configuration of this kind, each of the light bulbs is limited to a power of 40 Watts in order to be in accordance with current -standards, so- called class 2. Acscording to current standards, the installation cable, i.e. the cable .supplying the outlet, should not lie above 70°C. Naturally, this is li_miting from the lighting aspect and results in other c»r_3umer- related drawbacks. Ihe present invention relates to a lamp suspension which .solves the aforesaid problem and -which allows the use of two light bulbs each of 60 Watts within the confines of the class 2 regulation. Thus, the invention relates to a lamp fitting, a so-called wall-mounted or lamp fitting comprising an atta iment plate which is intended to be secured to an attac-hment surface, such as a ceiling surface or a wall surface in the vicinity of an inst_allation cable provided with an electric current outlet and which is intended to support at least one bulb holder, said holder or holders being connected electrically to the current outlet on the side of the attachment plate facing -.-.wards the a-ttac__-iτent surface. The lamp fitting is mainly characterized in that the attachment plate which is intended to lie remote from the attac-hment surface is provided with a reflecting device which is located at least in the vicinity of an attachment-plate part which is intended to be located in the vicinity of the installation cable, thereby limiting the temperature in the vicinity of said installation cable when the lamp is illuminated. The invention will now be described in more detail with reference to an exemplifying emb __Lment thereof and also with reference to the acxxaipaπying drawings, in which Figure l illustrates schematically a first e_r±χ-*diment of an inventive, c^il__ng-_K_unted lamp fitting, a lamp suspension, said Figure showing the lamp fitting in a horizontal view transversely to the connecting line between the two lamp holders of said fitting; Figure 2 shews the lamp fitting of Figure 1 as seen from the left in said Figure; and Figure 3 shows the lamp fitting of Figures 1 and 2 as seen from beneath in Figure 1. Figures 1-3 illustrate a lamp suspension 1 cσrnprising an attac-riinent plate which is intended to be located in the vicinity of, or in connection with, an electric outlet 2 from which electric current is taken to the lamp installation cable 3. The at-ac±_nent plate is _ tende-l to be secured to an attac-hment surface 4, such as a ceiling surface 4 or a wall, and supports two lamp bulbs 5 1 each in a respective holder 5, said holders being ..ntended to be connected electrically to the aforesaid outlet 2 on the side of the at-tac-hment plate which faces towards the attac-hrnent surface 4. The illustrated laπp fitting also includes a reflecting device 6 which is seated on the side of the at-tac-nment plate remote from the lamp-supporting surface, i.e. on the same side of the plate as that on which the lamps are seated. Hie reflecting device 6 is located at least in the close prciximity of an attac-hment-plate part 7 which lies close to the installation cable, ..aid reflecting device functioning to restrict the teiuperature in the i rnediate vicinity of the connection cable when the lamp is illuminated. According to one preferred embodi-trent of the invention, the device 6 is comprised essentially of a metallic-resilient and bright-polished plate 6' . It is also preferred that at least a part of the aforesaid reflecting device is convex in relation to the said attac__ment surface. In the case of the illustrated embcx-Li-neπt, the reflecting plate has a pro-truding part 8 which defines a cavity 8' which is intended to face towards and be connected to the installation cable, wherein the reflecting device surrounds the pro-truding part, either αampletely or partially. There is preferred a lamp fitting construction which includes two mitually spaced lamp holders with an elongated, protruding part 8 disposed between the holders, wherein said reflecting device extends along the prαt__τιding part in a tunnel-like configuration. According to another preferred embodiment, the resilient, bright plate has a generally square or rectangular configuration and includes mutually facing flange parts 9 which coact with stop means 10 provided on the plate, said plate being intended to be bent to a convex shape and to be held in position by the coaction between the flange parts and the stop means. The manner in -which the illustrated lamp fitting functions in accordance with the present invention will be understood in all essentials from the aforegoing. The reflexivity of the device 6 will reduce the heat load on the installation cable, by reflecting thermal radiation. According to preferred embodiments, the area around the installation cable is ventilated through the protruding part of the plate disposed around the cable. It will also be understood that the invention provides essential technical advantages over the known -.-.chnique. A prime advantage is that higher lighting powers can be used. The invention has been described above with reference to one exemplifying embodj-ment thereof. It will be understood, however, that other er_bod__ments or minor modificatiαns and changes are conceivable without departing from the inventive concept. For example, the inventive fitting can be used together with one or severa light bulbs. Fι_r-her_nore, the aforesaid reflecting device need not be metallic, but may also be made of a plastic material provided with a reflecting surface, by c±ircfl-tύum plating for instance. The actual fitting suspension means may be of any suitable kind. Ihe illustrated lamp fitting is suspended, or incunted, by means of a pulling screw 11 which is provided with an eye or loop i-ntended for coaction with a hook 12 fitted to the attachment surface. The illustrated fitting attach- ent plate is provided with spacing dubs 13 which support against the attac___ment surface. Further, the outlet in the vicinity of the installation cable may be designe in several ways. The design shown is coπposed by a contact plate 14 attached to the attac_-_ment surface but an outlet in the form of a contact freely hanging down is also conceivable. The illustrated plate 1 also includes, shown in Fig 3 only, attachment devices 15, which include slotted parts in which an attachment tab or tag can be inserted for holding laπp shade parts or the like to the laπp fitting Reference 16 identifies an internally screw-threaded attachment for laπp shade parts of the like. The invention shall not be considered restricted to the aforedescribed em__c>d-_ments, since modifications and variations can be made wi-Uiin the scope of the following Claims.
