Definitions

  • the description refers to lighting devices.
  • One or more embodiments may refer to lighting devices using electrically-powered light radiation sources, for example solid-state light radiation sources such as LED sources.
  • a solution currently in use envisages mounting the light radiation source(s) on a support board substantially similar to a Printed Circuit Board (PCB), with the heat transmitted coming from said board towards a heat-sink.
  • PCB Printed Circuit Board
  • a reduced contact area between the board and the heat-sink can, therefore, result in an unsatisfactory level of heat dissipation.
  • Document WO 2012/147032 A1 discloses an LED lamp having a first and a second LED assembly.
  • Each LED assembly comprises at least one LED element with an LED chip and a carrier with a flat surface for carrying the LED chip.
  • the LED chip emits light with a main optical direction.
  • the first and second LED assemblies are mounted relative to each other so that at least a first LED element from the first LED assembly and a second LED element from the second LED assembly enclose a rotating angle between their respective flat surfaces with respect to an axis of rotation, so as to involve light angle between the first and second main optical directions.
  • the axis of rotation is parallel to a plane of a flat carrier surface of at least one LED element.
  • the first and second LED assemblies are arranged offset from each other parallel to the axis of rotation.
  • Document JP 2013 069860 A discloses exposure equipment using an LED light source device and including an LED unit in which LEDs are arranged on side faces of a support member and a reflection part 12 constituted by reflectors.
  • the reflectors are not formed integrally, and are attached individually to and along the side faces having the LEDs arranged thereon.
  • One or more embodiments aim to contribute to the production of lighting devices in which the dissipation of the heat produced by the light radiation sources during operation is facilitated.
  • this object can be achieved thanks to a lighting device having the characteristics referred to in claim 1 that follows.
  • the reference 10 indicates - as a whole - a lighting device that can use electrically-powered light radiation sources.
  • solid state light radiation sources such as, for example, LED sources.
  • the lighting device 10 exemplified in Figure 1 is substantially similar to an HB4-type "bulb" usable, for example, in the automotive sector.
  • a casing 12 can be identified, shaped (according to the application and use requirements, for example, according to the assembly requirements) and capable of comprising heat conductive material, such as a thermally-conductive plastic material or a light metal material.
  • the casing 12 can be made in such a way as to have heat-sink characteristics.
  • the casing 12 can be provided with a tabbed portion, indicated by 120, which can be exposed to an aeriform ventilation flow, which is spontaneous or possibly forced (for example, due to the presence of a fan).
  • Figure 1 presents the casing 12 of the device 10 cross-sectioned in an approximately median plane so as to highlight the presence of a support member body 100 that extends along a longitudinal axis X10 on which electrically-powered light radiation sources are mounted.
  • the body 100 comprises an end portion (distal), protruding from the casing 12, of an elongated structure 14, at least roughly similar to a sort of bar or rod inserted into the casing 12.
  • the light radiation sources that can be mounted on the body 100 may comprise solid-state light radiation sources, such as, for example, LED sources.
  • These light radiation sources (hereinafter, for brevity, referred to as LED sources) are indicated with pairs of numerical references 161a, 161b; 162a, 162b, etc. so as to highlight the possible arrangement in pairs of mutually opposed sources in a transverse direction with respect to the axis X10, with the pairs arranged in a staggered manner, along the direction identified by the axis X10, both in the longitudinal direction and in the angular direction, according to a solution roughly comparable to that of road signs mounted on a pole.
  • the body 100 (here exemplified as constituting the distal end portion of the structure 14) has respective mounting surfaces for the light radiation sources 161a, 161b; 162a, 162b, etc. with these surfaces defined by pairs of enlarged portions e.g. 141, 141b; 142a, 142b, etc. also being mutually opposed in a direction transverse to the axis X10, with the pairs arranged in a staggered manner along the direction identified by the axis X10.
  • the enlarged portions corresponding to the surfaces 141, 141b; 142a, 142b, etc. comprise support boards or plates comparable to printed circuit boards (PCB) which, in addition to allowing the assembly and electrical connection of the light radiation sources 161a, 161b; 162a, 162b, are capable of defining heat exchange surfaces between the light radiation sources mounted thereon and the support member body 100 (and, therefore, the structure 14 of which, in the example considered here, has the body 100 as the distal end).
  • PCB printed circuit boards
  • one of the boards can act as a "master" board, which is connected to the electric power supply lines (possibly control lines) of the sources 161a, 161b, 162a, 162b, indicated as a whole by 18 in Figure 2 . All this while the other boards, for example, those indicated with 141b, 142a and 142b are capable of acting as "slave” boards, able to receive the electric power supply signals (and possibly control signals) by means of additional electrically-conductive formations, not visible in the figures.
  • boards such as 141a and 14ab may comprise, in addition to the portion (e.g., enlarged) for mounting a respective light radiation source, a portion that extends on the body 100 (structure 14) so as to be able to increase the heat exchange surface.
  • One or more embodiments allow the overall dimensions of the lighting device 10 to be maintained (capable of being subject to regulations, such as, for example, ECE/SAE standards), improving the characteristics of heat exchange and, therefore, dissipation of the heat generated by the light radiation sources during operation.
  • the heat dissipation characteristics can be improved by using the solution exemplified in Figure 3 .
  • Figure 3 illustrates one of the light radiation sources (by way of example, the one indicated by 161a, mounted on the board 141a), which is provided, in a manner known per se, with a thermal areola or pad 1610.
  • the pad 1610 can be placed in a heat exchange relationship with the body 100 (structure 14) using a so-called thermally-conductive "path" 1410 (in practice a bar of electrically conductive material) provided (also here in a manner known per se) in such a way as to extend across the board 141a.
  • a so-called thermally-conductive "path” 1410 in practice a bar of electrically conductive material provided (also here in a manner known per se) in such a way as to extend across the board 141a.
  • the heat exchange path between the pad 1610 and the body 100 (structure 14) comprises, in addition to the path 1410, thermally-conductive masses 1410a, 1410b interposed respectively:
  • thermally-conductive masses 1410a, 1410b may comprise e.g. layers (in practice "drops") of welding material, for example, thermally-conductive welding paste.
  • One or more embodiments as exemplified herein envisage the presence of two pairs of heat exchange surfaces, namely the boards 141a, 141b and the boards 142a, 142b, on which two respective pairs of light radiation sources are mounted, i.e. LEDs 161a, 161b and LEDs 162a, 162b.
  • One or more embodiments may envisage a greater number of pairs of heat exchange surfaces/light radiation sources, for example, three or more pairs of heat exchange surfaces and a corresponding number of light radiation sources.
  • one or more embodiments as exemplified herein enable (without negatively affecting the overall dimensions of the lighting device 10) the provision of a lighting device with good optical characteristics, e.g. at the intensity/uniformity level of the distribution of the light radiation emitted by the sources 161a, 161b; 162a, 162b in a radial direction starting from the axis X10.
  • This effect can be further developed, preserving the assembly modes exemplified here and the heat dissipation characteristics associated therewith, by increasing the number of light radiation source pairs.
  • crossing refers to the directions and takes into account the fact that the various pairs of surfaces (141a, 141b; 142a, 142b, etc.) and sources (161a, 161b; 162a, 162b, etc.) can be distributed along the body 100 so as to be offset from each other both longitudinally and angularly with respect to the axis X10.
  • a support member for lighting devices may comprise an elongated thermally-conductive body (e.g., 100) extending in a longitudinal direction (e.g., X10) with a plurality of pairs (e.g., 141a, 141b; 142a, 142b) of heat exchange surfaces for mounting light radiation sources (e.g., 161a, 161b; 162a, 162b), sources that may not be part of the embodiment per se), with the surfaces of each pair being mutually opposed transversely with respect to the longitudinal direction of the elongated body and the pairs of the plurality of pairs being offset from each other in the longitudinal direction of the elongated body.
  • a support member for lighting devices may comprise an elongated thermally-conductive body (e.g., 100) extending in a longitudinal direction (e.g., X10) with a plurality of pairs (e.g., 141a, 141b; 142a, 142b) of heat exchange surfaces for mounting light radiation sources (e.g
  • One or more embodiments may comprise (at least two) pairs of heat exchange surfaces mutually opposed along a first direction and a second direction, respectively, the first direction and the second direction mutually crossing and transverse to the longitudinal direction of the elongated body.
  • the pairs of the plurality of pairs (for example, 141a, 141b; 142a, 142b) can be angularly offset from each other (for example by 90°, so as to be perpendicular to each other).
  • the heat exchange surfaces may comprise enlarged portions of the elongated body (e.g., in the form of boards applied thereto).
  • One or more embodiments may comprise respective mounting boards of light radiation sources at the heat exchange surfaces.
  • One or more embodiments may comprise a bar-like formation (e.g., 14) of thermally-conductive material having the elongated body as an end portion.
  • One or more embodiments may comprise a heat-dissipative casing (e.g., 12) (see for example the tabbing 120) with the bar-like formation inserted into the casing with the elongated body carrying the plurality of pairs of heat exchange surfaces protruding from the casing.
  • a heat-dissipative casing e.g., 12
  • the bar-like formation inserted into the casing with the elongated body carrying the plurality of pairs of heat exchange surfaces protruding from the casing.
  • a lighting device may comprise:
  • the light radiation sources can be configured to project light radiation radially away from the longitudinal direction of the elongated body.
  • the light radiation sources may comprise LED sources.
  • a method for producing lighting devices may comprise:
