Description

LED LAMP WITH REPLACEABLE LIGHT SOURCE
The present invention relates to a LED lamp in which it is possible to carry out the replacement of the only LED light source.
The LED lamps currently available on the market represent an enough cheap solution in the civil lighting field since, especially when compared with the incandescent or fluorescent lamps, assure both a greater life and less power consumption, under the same luminous intensity generated. However it also to be considered the fact that, in respect of a incandescent and/or fluorescent lamp, a LED lamp has higher system costs besides a lower absolute luminous intensity. Particularly this parameter in the products released from time to time on the market results always growing and it is, moreover, always associated to lower values of absorbed power, and therefore of power consumption, under the same luminous intensity generated. The trend of the LED-based lighting field is therefore to offer products more and more competing with other technologies, since the unit cost of the lighting produced by a LED lamp for each power unit absorbed results decreasing in time. This trend, however, conflicts with the still high system cost associated to the LED lighting. The light sources used in this kind of system are substantially made of semiconductors able to emit radiations in the visible range if crossed by a given current and, therefore, require, differently from other technologies, the presence of electronic controls dedicated and depending on the particular LED used in the system. Commonly a LED lamp needs the presence of, besides a transformer, a driver circuit whose function is to provide the right supply current to the particular LED or semiconductor adopted. The LED lamps nowadays purchasable are lamps integrating, due to manufacturing constraints, the just described electronic parts, thing that certainly increase their purchase cost. For this reason the LED lighting system cost results high both under installation and maintenance and modernization. To the starting cost of said system, indeed, it is necessary to add not only the replacement cost of the anymore operating lamps, but also the replacement cost of the lamps in place of more modern lamps that offer, as above said, a higher brilliancy under the same power absorbed. In every case it will be necessary to support costs of the electronic parts needed for the operation but not reusable for the new lamps. Main object of the present invention is therefore to provide a lamp using LED as light source, but allowing user for replace the only LED light source thus leaving the chance to reuse the preexisting driver circuit in the lighting system. In this manner the replacement cost due to a malfunction will be limited to the purchase of the only light source and not the whole lamp.
Other main object of the present invention is to provide a LED lamp whose light source is replaceable with another modern concept light source having less power consumption.
Further object of the present invention is to provide a LED lamp in which it is possible to replace the light source with another light source having different LED setting.
These and other advantages of the present invention will be more clear by reading the following detailed description of a preferred embodiment according to the present invention, with reference to the annexed drawings in which: fig. 1 is a perspective view of a preferred embodiment according to the present invention, fig. 2 is an exploded view of the embodiment in fig. 1, fig. 3 is an exploded view of some elements of the embodiment in fig. 1, fig. 4a is a plan view of the light source according to the preferred embodiment in fig.
1, fig. 4b is a perspective view of the light source in fig. 4a, fig. 5a is a perspective view of the electric connection according to the embodiment in fig- 1, fig. 5b is a perspective view of the supporting plate of the electric connection in fig. 5a, fig. 5c is a perspective view of a coupler element of the electric connection in fig. 5a, fig. 5d is a perspective view of the terminals of the electric connection in fig. 5a, fig. 6a is a plan view of the heat sink according to the embodiment in fig. 1, fig. 6b is a perspective view of the heat sink in fig. 6a, fig. 7a is a plan view of the closure element according to the embodiment in fig. 1, fig .7b is a perspective view of the closure element in fig. 7a. referring now to figs. 1 and 2, the led lamp 10 comprises a lens 6 and a sink 3 interconnected by the action of a pair of teeth 61 integral with said lens 6 and adapted to engage recesses 31 suitably formed onto the sink 3. In fig. 3 there is shown a LED lamp 10 with any lens 6 and comprising, as evident from the exploded view, above said sink 3, an electric connection 2, a LED light source 1 and a closure element 4, besides screws 5 for assembling LED lamp 10.
In fig. 4a there is shown a LED luminous source 1 comprising both an electronic board
41, of circular shape having a pair of recesses diametrically opposed each other, and a set of LED 43 placed thereon and electrically connected to a printed circuit whose electric terminals
42 are displaced each at one of said recesses. In fig. 4b there shown instead the underlying portion of the electronic board 41 and particularly a insulating strip 44. Said electronic board
41 is also provided with a first pair of through holes with axes Z and Z' diametrically opposed and a second pair of through holes with axes W and W, diametrically opposed as well. In fig. 5a there is reported a perspective view of the electric connection 2, comprising a supporting plate 21 made of insulating material having a pair of layers 22 made of conducting material shaped such that their projection on the plane of the supporting plate 21 results totally comprised in the same plane of the supporting plate 21. Said supporting plate 21 and said layers 22 are, moreover, provided with pairs of through holes with axes X and X' at the ends and Y and Y' at the middle portion of said supporting plate 21. Fig. 5c shows instead a perspective view of a coupler element 25 provided with a through hole with axis Y and a protuberance 26 with axis X. Finally, fig. 5d shows a perspective view of a terminal 27 of the electric connection 2, that is an axially symmetric element.
At this point the assembling, realized during the production process of the LED lamp 10, the electric connection 2 is performed by aligning a layer 22 to the supporting plate 21 along the axes X and Y of aforesaid holes and sticking said layer 22 to the supporting plate 21; subsequently a coupler element 25 is put onto one of said layers 22 such that the protuberance is engaged in the hole with axis X whilst the hole with axis Y of the coupler element 25, consequently due to the X -Y axle base, is coaxial with the holes with axis Y of the supporting plate 21 and the layer 22. At this point it is possible to insert a terminal 27 inside the hole with axis Y and the welding of the end of said terminal 27 of the coupler element 25, in turn welded, at the end of the supporting plate 21, onto the layer 22 lying under the coupler element 25. For the second coupler element 25 a similar assembling is carried out, once considering the holes with axes X' and Y' in place of the holes with axes X and Y. Figs. 6a and 6b show a heat sink 3 provided with a groove 32 on the bottom of which there is formed a pair of through holes with axes Y and Y' allowing the passage of the terminals 27 of the electric connection 2, once this has been housed into the groove 32. Said sink 3 is further provided with pairs of holes with axes Z, Z', W and W.
In such manner it is possible to manually carry out by using conventional tools, such as a screwdriver, the assembling of the LED luminous lamp 1 inserting the electric connection 2 into the groove 32 of the sink 3, the LED luminous source 1 into the sink 3 taking then care of rotating it so as to let the position of the coupler elements 25 to coincide to the one of the electric terminals 42, also corresponding to the concentricity of the holes with axes Z, Z', W and W of the LED luminous source 1 and the sink 3. At this point it is sufficient overlapping to the LED luminous source 1 the closure element 4 respecting the concentricity of the holes with axes Z1 Z', W and W so as to fasten all of the described elements by, for example, screws through aforesaid holes.
From the just provided description of the preferred embodiment according to the present invention it is possible to notice that said fastening screws for the manual assembling of the LED lamp 1 can be also used to allow fastening to a roof lamp preset with fastening holes having suitable axle base. In such case it will be possible the use of electric terminals 27 different and adapted to be connected suitably to electric cable provided on said roof lamp.
The present invention therefore provides a LED lamp in which it is completely easy the replacement of the only LED luminous source with others wherein there is a LED or a LED group having the same power but even more luminous intensity, keeping the driver circuit of the preceding LED luminous source. The aforesaid feature allows therefore the total disposal of welding to assure both the electric connection and the mechanical fastening between the LED light source and the remaining parts of the LED lamp, freeing the typical elements of a LED lamp one from another thus allowing a separate replacement without the use of industrial tools or welders for assembling the lamp; by simple mechanical tools it is therefore possible carrying out even in a common house environment the assembling, the replacement or even the installation of lamp parts having a LED or a LED group as light source.
