Definitions
- the description refers to lighting devices.
- One or more embodiments may be applied to lighting devices using electrically-powered light radiation sources, such as solid-state sources, for instance, LED sources.
- electrically-powered light radiation sources such as solid-state sources, for instance, LED sources.
- One or more embodiments may be applied to the automotive sector.
- LED light radiation sources in short, "lamps" or light bulbs - that can be used (for instance, at the retrofit level) instead of conventionallight radiation sources, for instance, of the filament type, being able to provide performance similar to conventional sources, for instance, regarding the distribution of the light radiation emitted.
- the automotive sector is a sector for which this application has proved to be of particular interest, first in relation to auxiliary light bulbs and then to bulbs for headlamps (H-type bulbs), usable, for instance, for low-beam headlights, high-beam headlights and/or fog lights.
- H-type bulbs headlamps
- a reference cap or ring may be envisaged, for instance, as specified in reference texts such as IEC Publication 60061.
- Such a reference ring can be fixed to the body of the headlight using an element such as a spring clip or a mechanical coupling.
- the emission pattern of the light radiation of these lamps or light bulbs may present directionality characteristics, being oriented in a lateral direction, for instance.
- the possibility of rotating the light radiation generator with respect to the mounting ring can therefore be envisaged, in order to obtain a desired orientation with respect to a surface of a reflector, for instance.
- One or more embodiments aim to contribute to provide improved solutions according to the criteria outlined above.
- this object can be achieved thanks to a mounting structure having the features recited in the following claims.
- One or more embodiments may relate to a corresponding lighting device (for instance, a lamp or bulb usable as a retrofit source in the automotive sector).
- a corresponding lighting device for instance, a lamp or bulb usable as a retrofit source in the automotive sector.
- One or more embodiments may concern a corresponding method.
- One or more embodiments facilitate producing LED lamps or light bulbs (for instance, H-type) that can be mounted and rotated in a desired position without having to resort to specific tools and/or particular complex operations.
- LED lamps or light bulbs for instance, H-type
- One or more embodiments may allow the orientation operation to be carried out with the light radiation sources already mounted, for instance, already mounted in the projector of a reflector or spotlight.
- One or more embodiments facilitate adjusting the angular position of the light radiation source by means of a pressure/rotation action that can be carried out without having to disassemble the assembly, for instance, without having to remove the lamp or bulb from the projector body.
- an embodiment in the context of the present description indicates that a particular configuration, structure or characteristic described in relation to the embodiment is included in at least one embodiment.
- sentences such as “in an embodiment”, which may be present at various points in the present description, do not necessarily refer to exactly the same embodiment.
- particular configurations, structures or characteristics can be combined in any suitable way in one or more embodiments.
- reference number 10 indicates - as a whole - a lighting device such as, for instance, a device that can be used as a lamp or a bulb usable (for instance, as a retro-fitting or "retrofit” element) instead of a conventional-type lamp or bulb, for instance, in the automotive sector.
- a lighting device such as, for instance, a device that can be used as a lamp or a bulb usable (for instance, as a retro-fitting or "retrofit” element) instead of a conventional-type lamp or bulb, for instance, in the automotive sector.
- the device 10 may comprise a mounting structure comprising a bearing or supporting part or portion (hereinafter “carrier portion") 11 on which one or more electrically-powered light radiation generators can be mounted.
- carrier portion a bearing or supporting part or portion
- electrically-powered light radiation generators L see the power cable indicated with C
- solid-state light radiation generators LEDs, for instance.
- the carrier portion 11 comprises an elongated body 110, for instance, with a finger-like shape, having a ring portion 12 (in the examples illustrated here, a circular annular portion with an closed ring) fitted thereon.
- the elongated body 110 can extend along a longitudinal axis X10 between:
- the or each of the generators L may comprise a support plate or board substantially similar to a printed circuit board (PCB) having a planar shape having a bearing surface having one or more light radiation generators mounted thereon.
- PCB printed circuit board
- the distal end 110b of the elongated body 110 may present a narrowing (a sort of "flattened” part) with two mutually opposite and parallel planar faces, each of which carries a generator L mounted thereon (only one of these is visible in the figures).
- the elongated body 110 of the carrier portion 11 may comprise thermally-conductive material and extend at the end 110b at the light radiation generator(s) L, for instance, according to a sandwich structure between two generators L arranged on the opposite faces of the flattened portion of the end 110b.
- the generators L can be placed at the same distance with respect to a median reference plane of the emission volume of the light radiation at the axis X10.
- Such a solution facilitates obtaining a emission configuration of the light radiation starting from the device 10 similar to that obtainable with a lamp or incandescent bulb.
- the portion 11 can be mounted in a reflector R (the outline of which is represented with dotted lines in Figures 1 , 6 and 11 ), with the light radiation generator(s) L able to be placed in a position at least approximately focal with respect to this reflector R, which can have a general vat-like shape, for instance parabolic.
- Such a structure facilitates fixing of the generator (s) with respect to the reflector R (or, in general, with respect to a light or projector in which this is included), as well as the dissipation of the heat produced during operation (thanks to propagation of the heat produced from the generator(s) L along the elongated body 110 towards the heat sink at the end 110a).
- the relative positioning (axial and angular) of the carrier portion 11 and of the ring portion 12 (which can be fixed to the reflector R according to known criteria) facilitates achieving a condition in which the light radiation of the generator(s) L can be emitted by the reflector R according to a desired radiation configuration, for instance, a configuration similar to that obtainable with a conventional incandescent light radiation source. This can take place in accordance with specifications that establish (for instance, for category-H lamps) the presence of certain cut-off angles at which it no light radiation emission is desired.
- the aforesaid containment or restraint action facilitates the (firm) mounting of the device 10 on the reflector R, for instance.
- the aforesaid rotation movement (which may be actuated in discrete steps of equal or different values that can be determined precisely) facilitates the orientation of the generator (s) with respect to the reflector R.
- the carrier portion 11 can perform, for instance, at the end 110a, a heat dissipation function, with the elongated body capable of facilitating heat conduction starting from or the generator(s) L.
- the carrier portion 11 may comprise thermally-conductive material, such as metal material (e.g. aluminum or light alloys) or thermally-conductive plastic material.
- the ring portion 12 may comprise plastic material - e.g. polymers - or metal materials - e.g. aluminum or light alloys.
- carrier portion 11, ring portion 12 these can either be a single material, or different materials, for instance, coupled by means of over-molding.
- Figures 3 and 4 exemplify possible implementation methods wherein the ring portion 12 may have, on the inner surface of the axial orifice of the ring (which should be centered with respect to the axis X10) a step-like formation comprising, e.g. two or more arch-shaped engagement elements 121 (for instance step-shaped, which can assume one piece with the ring-shaped body) separated by one or more channels 122 extending in an axial direction with respect to the ring-shaped portion 12 (therefore along the axis X10).
- a step-like formation comprising, e.g. two or more arch-shaped engagement elements 121 (for instance step-shaped, which can assume one piece with the ring-shaped body) separated by one or more channels 122 extending in an axial direction with respect to the ring-shaped portion 12 (therefore along the axis X10).
- the or each of the channels 122 can, therefore, form a passage through which (with the ring portion 12 fitted on the elongated body 110 and made to advance axially on the elongated body with respect to the axis X10, e.g. towards the end 110a) a respective pin or tooth 111 can pass, which projects radially with respect to the elongated body 110.
- two or more pins or teeth 111 can be provided, for instance (diametrically opposite, for instance), which can slide along corresponding channels 122, which are also diametrically opposite: see in this respect Figures 5A to 5D - which can be considered, at least approximately, as end views of the device 10 observed starting from the end 110b of the carrier portion 11.
- one or more embodiments as exemplified in Figures 1 and 4 can provide a coupling configuration of the ring portion 12 and the elongated body 110 of the carrier portion 11 to a certain extent similar to a bayonet coupling wherein, when the pin or pins 111 are not aligned with the channel (s) 122 (which can occur in a range of angular positions substantially identified by the circumferential extension of the step formations 121), the ring portion 12 can be retained on the elongated body 110, counteracting its moving away with respect to the end 110a, since the pins or teeth 111 abut against an engagement surface 1210 of the step formations 121 which extends in a transverse direction with respect to the axis X10.
- the step formation(s) 121 can have a surface 1210 (facing away from the end 110a, in the examples presented here, which are such) having a sculptured pattern given by a wavy or a tooth-shaped profile.
- This pattern can give rise to a plurality of different possible positions of coupling or abutment of the tooth or teeth 111 against the formation(s) 121 (see the arrow festoon half-way up Figure 4 ).
- These different possible positions of coupling or abutment can correspond to different relative angular positions of the ring portion 12 with respect to the elongated body 110 (therefore with respect to the carrier portion 11) about the axis X10, within an angular adjustment range exemplified by the angles ⁇ in Figure 5D .
- the profiles of the wavy or toothed surface 1210 can be defined to correspond to angular adjustment steps of about 15°.
- the aforesaid adjustment steps can therefore identify corresponding adjustment positions of the orientation of the light radiation generator(s) L with respect to the surface of the reflector R, so as to achieve a desired adjustment condition.
- an elastic member such as an elastic ring (O-ring) 102 can be fitted on the elongated body 110 of the carrier portion 11 (for instance, between the end with heat sink 110a and the ring portion 12), configured to generating an elastic preload or bias (see for instance the arrows at the bottom of Figure 4 ), which urges the surface 1210 of the formations 121 and the tooth or teeth 111 into a condition of mutual contrast or abutment, so as to firmly maintain the coupling condition between the carrier portion 11 and the ring portion 12 at the desired (angular) adjustment value.
- an elastic member such as an elastic ring (O-ring) 102 can be fitted on the elongated body 110 of the carrier portion 11 (for instance, between the end with heat sink 110a and the ring portion 12), configured to generating an elastic preload or bias (see for instance the arrows at the bottom of Figure 4 ), which urges the surface 1210 of the formations 121 and the tooth or teeth 111 into a condition of mutual contrast or abutment, so
- the tooth or teeth 111 in view of the possible presence of this elastic biasing force, can be made of metal material capable of adequately withstanding this stress.
- the ring portion 12 is provided with a crown of springing teeth 123 (also in this case a centered condition with respect to the axis X10 is assumed) extending distally in the axial direction from the ring portion 12 with terminal ends protruding inwardly of the ring portion 12.
- the teeth 123 directed towards the end 110a (heat sink) of the elongated body 110, for instance, are capable of engaging (for instance, by snap-engagement, thanks to the elasticity of the respective root parts 1230) a groove 124 that extends around the axis X10 on the surface of the elongated body 110 in a plane transverse to the axis X10.
- the ring portion 12 can retain a certain rotational capacity with respect to the elongated body 110 about the axis X10 given by the possibility of the teeth 123 to slide circumferentially inside the groove 124.
- This sliding movement (and angular orientation of the ring portion 12 with respect to the elongated body 110 of the carrier portion 11) can be adjustable in steps as a result of the possible sculptured configuration of the groove 124, given for instance by the presence of raised teeth 1240 emerging from the bottom wall of the groove 124 itself.
- the relative angular position of the ring portion 12 with respect to the elongated body 110 can be adjusted by discrete steps (for instance, with an angular value of 22.5°) taking advantage of the fact that as a result of relative rotation imparted to the ring portion 12 with respect to the elongated body 110, the teeth 123 are at least slightly elastically spread out so as to be able to overcome the projections 1240.
- Figure 10B exemplifies the possibility of adjusting the angular position of the ring portion 12 with respect to the elongated body 110 about the axis X10 within an adjustment range ⁇ which may correspond to one, two, or three times the step of angular adjustment of 22.5° (this is, of course, a purely exemplary value) identified by the mounting positions of the teeth 123.
- an elastic member 102 such as, for instance, an elastic ring (O-ring) which can provide an elastic biasing force (for instance, in the direction of moving the ring portion 12 away from the end 110a) capable of reinforcing (also thanks to the hook shape of the teeth 123) the coupling condition and the relative angular position between the ring portion 12 and the carrier portion 11.
- an elastic member 102 such as, for instance, an elastic ring (O-ring) which can provide an elastic biasing force (for instance, in the direction of moving the ring portion 12 away from the end 110a) capable of reinforcing (also thanks to the hook shape of the teeth 123) the coupling condition and the relative angular position between the ring portion 12 and the carrier portion 11.
- Figures 11, 12 and 13A-13C (in which, once again, parts or elements similar like parts or elements already presented in connection with the previous figures are indicated with like references, thus making it unnecessary to repeat herein corresponding detailed description superfluous) can be seen as representing a simplification of the solution exemplified in Figures 6 to 9 and 10A, 10B .
- One or more embodiments as illustrated in Figures 11, 12 and 13A-13C , for instance, can provide for the presence of only two springing teeth 123 placed at diametrically opposite positions with respect to the development of the ring portion 12 around the axis X10.
- the groove 124 may have a wall - for instance, the bottom wall 1240 - sculptured with a comb-like wavy serrated profile, in substantial analogy with the surface 1210 visible in Figures 3 and 4 .
- the relative angular position of the ring portion 12 and of the elongated body 110 around the axis X10 can be adjusted within an angular range ⁇ operating in steps corresponding to different possible angular coupling positions of the teeth 123 (see, for instance, Figures 11 and 12 ) with successive undulations/teeth of the bottom wall 1240 of the groove 124.
- One or more embodiments as exemplified in Figures 11, 12 and 13A, 13B and 13C envisage providing the aforesaid discretization by steps of the range of possible angular adjustment by acting on the profile of the groove 124 instead of on the pitch of angular distribution of the teeth 123 as is the case of the solution exemplified in Figures 6 to 9 and 10A, 10B .
