Detailed Description
According to a first aspect of the inventive concept, these and other objects are achieved, in whole or at least in part, by a lamp assembly comprising: a main body; a circuit board including a light source, wherein the circuit board is disposed in the main body; an outer bulb configured to mate with the body; and an inner bulb shell arranged inside the outer bulb; wherein the outer bulb comprises at least one first coupling element and the inner bulb comprises at least one second coupling element, wherein the at least one first coupling element and the at least one second coupling element are arranged to cooperate with each other for securely mounting the inner bulb with respect to the outer bulb.
The inventive concept is based, at least in part, on the recognition that: by making the inner bulb and the outer bulb cooperate and in turn making the outer bulb and the main body cooperate, a more space efficient structure can be achieved. In contrast, conventional lamp assemblies include separate connections between the inner bulb shell and the main body and between the outer bulb and the main body, respectively. By omitting one of these connections (e.g., the connection between the inner bulb and the body), more space may be provided for other components of the lamp assembly.
It is a further insight of the inventors that a lamp assembly according to the inventive concept provides an improved alignment of the optical axis of the inner bulb and the optical axis of the outer bulb. Such alignment may improve the optical characteristics of the lamp assembly. It may thus be noted that in the present inventive concept the inner bulb and the outer bulb are mutually cooperating separate structures.
In the present disclosure, reference is made to the optical axes of the inner bulb and the outer bulb, respectively. Such an optical axis may be the symmetry axis of the inner bulb and the outer bulb, respectively. In particular, the outer bulb may have a substantially conical or frustoconical shape and the inner bulb may have a substantially conical or frustoconical shape and the optical axis may be the central axis of the inner bulb and the outer bulb, respectively.
For clarity, a reference system will be used throughout the present disclosure, wherein the body is disposed substantially "below" the outer bulb, i.e., wherein the body defines a lower portion of the lamp assembly and the outer bulb defines an upper portion of the lamp assembly. Any reference to a feature being "above" or "below" any other feature is made with respect to such a reference system.
At least one first coupling element and at least one second coupling element may be arranged on the outer periphery of the outer bulb and the inner bulb, respectively. Thereby, a simple coupling arrangement may be achieved. Furthermore, by arranging the at least one first coupling element and the at least one second coupling element on the outer periphery of the outer bulb and the inner bulb, respectively, space towards the central axis of the lamp assembly is provided for other components.
In particular, the outer bulb may comprise an annular periphery and the inner bulb may comprise an annular periphery. The at least one first coupling element and the at least one second coupling element may be arranged on a lower half or a lower portion of the outer periphery of the outer bulb and the inner bulb, respectively. In particular, the at least one second coupling element is arranged at the end of the inner bulb facing away from the outer bulb, i.e. at the end of the open end of the inner bulb.
The at least one first coupling element may comprise an opening and the at least one second coupling element may comprise a protrusion, wherein the protrusion is configured to be inserted into the opening. Thereby, the outer bulb and the inner bulb can be fitted to each other.
The outer bulb may comprise a flange in which the at least one first coupling element is arranged. In particular, in case the at least one first coupling element comprises an opening and the at least one second opening comprises a protrusion, the flange may comprise a recess arranged at the opening, wherein the recess is configured to accommodate the at least one protrusion when the outer bulb is mated with the inner bulb shell. Further, the protrusion and recess may be configured such that the protrusion is flush with the flange or recessed in the recess relative to an outer surface of the flange. In other words, the recess and the protrusion may be configured such that the protrusion does not protrude beyond the outer surface of the flange. The flange may be configured to abut an inner surface of the body when the outer bulb is mated with the body. In particular, the outer surface of the flange may be configured to abut the inner surface of the body when the outer bulb is mated with the body.
The projection may comprise a fixing portion configured to abut an outer surface of the outer bulb when the inner bulb shell and the outer bulb are in the fixed configuration. The fixing portion may be formed as an integral part of the protrusion or as a separate part of the at least one second coupling element. The fixing portion may provide a firm mutual fit of the outer bulb and the inner bulb. In particular, the fixation portion may prevent or reduce movement of the inner bulb and the outer bulb relative to each other in a radial direction relative to the optical axis. The fixation portion may include a recess configured to receive a corresponding protrusion disposed in the opening of the first coupling element. Thereby, an improved firm connection between the inner bulb and the outer bulb may be achieved.
The at least one second coupling element may comprise an opening, and wherein the at least one first coupling element comprises a protrusion, wherein the protrusion is configured to be inserted into the opening. Thereby, the outer bulb and the inner bulb can be fitted to each other.
The projection may comprise a fixation portion configured to abut an inner surface of the inner bulb shell when the inner bulb shell and the outer bulb are in the fixed configuration. The fixing portion may be formed as an integral part of the protrusion, or as a separate part of the at least one second coupling element, similar to that disclosed above. The fixing portion may provide a firm mutual fit of the outer bulb and the inner bulb. In particular, the fixation portion may prevent movement of the inner bulb and the outer bulb relative to each other in a radial direction relative to the optical axis. In particular, the fixation portion may prevent or reduce relative movement of the inner bulb and the outer bulb in a radial direction with respect to the optical axis. The fixation portion may comprise a recess configured to receive a corresponding protrusion arranged in the opening of the second coupling element. Thereby, an improved firm connection between the inner bulb and the outer bulb may be achieved.
The inner bulb and/or the outer bulb may be made of a flexible material such that: even in the case where the projections are of equal or slightly larger size compared to the openings, the projections on either the inner bulb shell or the outer bulb are allowed to be inserted into the corresponding openings in the other of the inner bulb shell and the outer bulb. Thereby, the fitting of the outer bulb and the inner bulb shell may be facilitated and a firm connection between the outer bulb and the inner bulb shell may be achieved.
The lamp assembly may include: at least two first coupling elements arranged radially symmetrically about the optical axis of the outer bulb; and at least two second coupling elements arranged radially symmetrically around the optical axis of the inner bulb. Thereby, the force acting on either the outer bulb or the inner bulb, which forces cause a movement of either the outer bulb or the inner bulb relative to the other, can be distributed between the plurality of coupling elements. In particular, arranging the at least two first coupling elements radially symmetrically around the optical axis of the outer bulb and the at least two second coupling elements radially symmetrically around the optical axis of the inner bulb may provide a symmetric distribution of forces acting on either the inner bulb or the outer bulb.
The body may include electrical contacts configured to provide an electrical connection between the circuit board and the electrical grid. Thereby, the lamp assembly may be connected to an electrical grid for powering the light source of the lamp assembly. The electrical contacts may be further configured to mechanically connect the lamp assembly to the socket.
The outer bulb may comprise at least one first main coupling element and the body may comprise at least one second main coupling element, wherein the at least one first main coupling element and the at least one second main coupling element are arranged to cooperate with each other for securely mounting the outer bulb with respect to the body. Thereby, the outer bulb and the body can be fitted to each other. Furthermore, the inner bulb mounted with respect to the outer bulb may be indirectly fixed with respect to the main body.
The inner bulb may comprise at least one first main coupling element and the body may comprise at least one second main coupling element, wherein the at least one first main coupling element and the at least one second main coupling element are arranged to cooperate with each other for securely mounting the inner bulb with respect to the body. Thereby, the inner envelope and the main body can be fitted to each other. Furthermore, the outer bulb mounted with respect to the inner bulb shell may be indirectly fixed with respect to the main body. In other words, as described in the previous paragraph, the inner bulb shell and the outer bulb may be mounted with respect to each other, and the outer bulb (still mounted with respect to the inner bulb shell) may then be mated with the main body. Furthermore, as described in the current paragraph, the inner bulb shell and the outer bulb may be mounted relative to each other, and the inner bulb shell (still mounted relative to the outer bulb) may then be mated with the main body.
The at least one first primary coupling element may comprise a primary protrusion and the at least one second primary coupling element may comprise an opening. The primary projection may be configured to be inserted into the primary opening. Thereby, the outer bulb and the body can be fitted to each other. The reverse is also possible, i.e. the at least one first main coupling element comprises a main opening and the at least one second main coupling element comprises a main protrusion. Other arrangements for coupling the outer bulb to the main body are contemplated within the scope of the inventive concept.
The at least one first main coupling element may be arranged lower than the at least one first coupling element.
The light source may be an L ED light source the inventive concept may be particularly advantageous in lamp assemblies that include a L ED light source because such lamp assemblies may utilize space provided within the lamp assembly L ED light sources may be arranged in connection with RF (radio frequency) boards and/or other components including a heat sink for dissipating heat from the L ED light source, a circuit board connected to the L ED light source and holding L ED light source, and a reflector for reflecting light emitted from the light source.
The outer bulb and the inner bulb shell may be candle-shaped.
The inner bulb and the outer bulb may be configured to be light transmissive.
According to a second aspect of the inventive concept, these and other objects are achieved, in whole or at least in part, by a method for assembling a lamp assembly, wherein the method comprises: arranging a circuit board including a light source in a main body; fixedly mounting the outer bulb relative to the inner bulb via at least one first coupling element of the outer bulb and at least one second coupling element of the inner bulb such that the inner bulb is arranged within the outer bulb, the at least one first coupling element and the at least one second coupling element being arranged to cooperate with each other for fixedly mounting the inner bulb relative to the outer bulb; and mating the outer bulb with the body.
Thereby, a simple method of assembling the lamp assembly may be provided. In particular, the inner bulb may be mated with the outer bulb prior to mating the outer bulb with the body. In contrast, conventional lamp assemblies require the inner bulb shell to be coupled to the main body and the outer bulb to be coupled to the main body.
Features described in relation to one aspect may also be incorporated in other aspects and the advantages of such features apply to all aspects in which they are incorporated.
Other objects, features and advantages of the present inventive concept will appear from the following detailed disclosure, from the appended claims as well as from the drawings.
In general, all terms used in the claims are to be interpreted according to their ordinary meaning in the technical field, unless explicitly stated otherwise herein. Moreover, the use of the terms "first," "second," and "third," etc. herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. All references to "a/an/the [ element, device, component, means, step, etc ]" are to be interpreted openly as referring to at least one instance of said element, device, component, means, step, etc., unless explicitly stated otherwise. The steps of any method disclosed herein do not have to be performed in the exact order disclosed, unless explicitly stated.
FIG. 1 illustrates a lamp assembly 100, the lamp assembly 100 comprising: a main body 102; a circuit board 104, the circuit board 104 including a light source 106, wherein the circuit board 104 is disposed in the body 102; an outer bulb 108, the outer bulb 108 configured to mate with the body 102; and an inner bulb shell 110, the inner bulb shell 110 being arranged within the outer bulb 108. The outer bulb 108 comprises at least one first coupling element 112 and the inner bulb 110 comprises at least one second coupling element 114. The at least one first coupling element 112 and the at least one second coupling element 114 are arranged to cooperate with each other for securely mounting the inner bulb 110 with respect to the outer bulb 108. For clarity, the proximal end 101 and distal end 103 of the lamp assembly 100 are defined herein.
The outer bulb 108 has an optical axis A1. Similarly, the inner bulb 110 has an optical axis A2。
The illustrated figure also shows a driver printed circuit board assembly 109, the driver printed circuit board assembly 109 being housed within the main body 102 below the circuit board 104 a reflector 116 in the form of a ring-shaped structure is disposed around the light sources 106 (here a group L ED), and further, a Radio Frequency (RF) board 118 is disposed within the main body 102.
Here, the first main coupling element 122 of the outer bulb 108 is arranged below the first coupling element 112 of the outer bulb 108. In other words, the first main coupling element 122 is arranged closer to the proximal end 101 than the first coupling element 112. Furthermore, the first main coupling element 122 is arranged below the second coupling element 114. In other words, the first main coupling element 122 is arranged closer to the proximal end 101 than the second coupling element 114. Also, the second coupling element 114 is arranged at the end of the inner bulb facing in the direction of the proximal end 101. Thus, there is an axis A1And A2An orthogonal plane or volume in which the first main coupling element 122 of the outer bulb 108 occupies space, but the second coupling element 114 of the inner bulb 110 does not. Thus, more space is available in this plane for other features, such as the RF board 118, the circuit board 104, and/or a heat sink (not shown). Such a plane is more clearly illustrated in connection with fig. 2. Further, the second coupling element 114 may interact with one or more of the components of the circuit board 104, the RF board 118, the reflector 116, and the driver printed circuit board assembly 109, such that a more reliable connection of these components is achieved.
Referring now to fig. 2 in conjunction with fig. 1, a close-up of the first coupling element 112, the second coupling element 114, and the first main coupling element 122 is shown. It may be noted that here the outer bulb 108 and the inner bulb shell 110 are in a mated configuration. In the illustrated embodiment, the first coupling element 112 includes an opening 124 and the second coupling element 114 includes a protrusion 126. Note that in the illustrated cross-sectional view, only a portion of the opening 124, a portion of the protrusion 126, and a portion of the first primary coupling element 122 are illustrated.
Here, the outer bulb 108 comprises a flange 128, and the opening 124 is arranged on the flange 128. Further, a recess 130 is arranged at the opening 124, wherein the recess 130 is configured to receive the protrusion 126. In particular, recess 130 and protrusion 126 are configured such that protrusion 126 is recessed within recess 130, or protrusion 126 is flush with outer surface 132 of flange 128, such that protrusion 126 does not protrude beyond outer surface 132 of flange 128.
Here, the protrusion 126 includes a fixing portion 134, the fixing portion 134 being configured to abut an outer surface of the outer bulb 108. It may be noted that the outer surface of the outer bulb 108 is not visible in this view, as it is blocked by the protrusion 126 and the fixing portion 134. The fixing portion 134 may prevent or reduce movement of the inner bulb 110 and the outer bulb 108 relative to each other in the radial direction R. Here, the fixing portion 134 extends generally upward toward the distal end of the lamp assembly when the inner bulb shell 110 is mated with the outer bulb 108 and the outer bulb 108 is mated with the body (not shown). In other words, the fixing portion 134 extends away from the first main coupling element 122. However, it is also contemplated that the fixation portion 134 may extend toward the first main coupling element 122, i.e., toward the proximal end of the lamp assembly, when the inner bulb shell 110 is mated with the outer bulb 108 and the outer bulb 108 is mated with the body (not shown).
Here, the protrusion 126 includes an inclined surface 136. In the assembled configuration, i.e. when the inner bulb shell is inserted into the outer bulb (corresponding to the inner bulb shell being securely mounted relative to the outer bulb), the inclined surface 136 is inclined relative to the lower surface 138 of the outer bulb 108. When the inner bulb shell 110 is inserted into the outer bulb 108 through the main opening 140 in the outer bulb 108, and the inner bulb shell 110 and the outer bulb 108 are forced towards each other, the inclined surface 136 abuts the lower surface 138 and urges the protrusion 126 inwardly towards the optical axis of the inner bulb shell 110, such that the protrusion 126 is pushed into the inner surface 142 of the outer bulb 108. Thus, the mating of the inner bulb shell 110 with the outer bulb 108 is facilitated and may be accomplished by pushing the inner bulb shell 110 upward toward the distal end 103 of the lamp assembly.
Similar to the inclined surface 136 of the protrusion 126, the first primary coupling element 122 may include a primary inclined surface 144, the primary inclined surface 144 being inclined with respect to an upper surface of the main body (not shown). Furthermore, the main body may comprise a second main coupling element (not shown) arranged to cooperate with the first main coupling element 122 for securely mounting the outer bulb relative to the main body. Thus, the outer bulb 108 may be mounted to the body in the following manner: the outer bulb 108 and the body are urged toward each other, thereby urging the first primary coupling element 122 within the inner surface of the body (not shown) and causing the first primary coupling elements to interfit. The first primary coupling element 122 may comprise a primary protrusion and the second primary coupling element may comprise an opening configured to receive the primary protrusion for securely mounting the outer bulb relative to the body.
A plane P is illustrated which is orthogonal to the optical axes (not shown) of the inner bulb and the outer bulb, respectively, wherein the first main coupling element 122 of the outer bulb 108 occupies space, but wherein the second coupling element 114 of the inner bulb 110 does not occupy space. There is no part of the inner bulb 110 in the plane P, thereby eliminating the footprint (footprint) of the inner bulb 110 in the plane P. As can be seen in the figures, there can be a plurality of planes P which define a volume V in which the footprint of the inner bulb is eliminated.
Referring now to fig. 3, the outer bulb 108 and the inner bulb shell 110 are shown. Here, the outer bulb 108 comprises three first coupling elements 112a, 112b, 112c and the inner bulb shell 110 comprises three second coupling elements 114a, 114b, 114 c. It should be noted, however, that it is contemplated that the outer bulb 108 may include at least one first coupling element, such as two, three, four, or more first coupling elements. Similarly, the inner bulb 110 may include at least one second coupling element, such as two, three, four, or more second coupling elements.
Three first coupling elements 112a, 112b, 112c surround the optical axis a1Radially symmetrically arranged and three second coupling members 114a, 114b, 114c surrounding the optical axis a2And the radial direction is symmetrical.
A method for assembling the lamp assembly 100 according to the present inventive concept will now be described with reference to fig. 4 a-4 g. For clarity and simplicity, the method will be described in terms of "steps". It is emphasized that the steps are not necessarily temporally defined or separate processes from each other, and that multiple "steps" may be performed concurrently in a parallel fashion. It is noted that some of the steps disclosed below are optional.
The method for assembling the lamp assembly 100 may include: optional step 360, disposing the driver printed circuit board assembly 109 in the body 102; optional step 362, disposing the heat sink 146 in the body 102 over the driver printed circuit board assembly 109; step 364, disposing the circuit board 104 including the light source 106 in the body 102; optional step 366, disposing a reflector 116 over the circuit board 104; optional step 368, attaching the electrical contacts 148 to the body 102; a step 370 of securely mounting the outer bulb 108 relative to the inner bulb 110 via at least one first coupling element of the outer bulb and at least one second coupling element of the inner bulb, such that the inner bulb 110 is arranged within the outer bulb 108, the at least one first coupling element and the at least one second coupling element being arranged to cooperate with each other for securely mounting the inner bulb 110 relative to the outer bulb 108; and step 372, mating the outer bulb 108 with the body 102, thereby forming the lamp assembly 100.
The inventive concept has mainly been described above with reference to a few embodiments. However, as is readily appreciated by a person skilled in the art, other embodiments than the ones disclosed above are equally possible within the scope of the inventive concept, as defined by the appended patent claims.
