Description

“Linear lamp, furnishing element”***DESCRIPTION

[0001] . Field of the invention

[0002] . The present invention relates to a linear lamp as well as to a furnishing element.

[0003] . Background art

[0004] . Within the scope of lighting a space, e.g., a room or a compartment of a furnishing element, it is known to illuminate by diffusing the light radiation emitted by a light source.

[0005] . The diffusion of the light radiation is possible by the indirect illumination of the space to be lit and / or by the light radiation passing through a diffusing element such as a diffusing cover, for example, configured to deflect, by scattering, the light radiation a plurality of times before leaving the cover and thus ensuring a homogeneous and non-direct lighting.

[0006] . Within the scope of lighting the space under or inside a furnishing element, e.g., a shelving unit or wardrobe, or a display cabinet, or again under a hanging wall unit, it is known to provide linear lamps for diffusing the light radiation which extend mainly along a longitudinal direction, e.g., a straight and / or curvilinear longitudinal direction, which are connected, e.g., recessed, along portions of the furnishing element, wither vertical, such as uprights, or horizontal, such as a shelf and / or the base portion and / or the cap portion of the furnishing element, for example.

[0007] . Such linear diffusing lamps comprise a plurality of light sources, such as an LED strip, for example, a support portion, e.g., a profile made of metal or polymer material, configured to be connected to the furnishing element, e.g., housed in a seat obtained in portions of the furnishing element, and configured to support the plurality of light sources, and a diffusing cover configured to diffuse the light radiation emitted by the plurality of light sources.

[0008] . In certain solutions, the diffusing cover comprises a diffusing portion parallel to the surface of the portion of the furnishing element to which it is connected, e.g., parallel to the horizontal direction, configured to diffuse the light radiation emitted by the plurality of light sources.

[0009] . However, with this solution, the light radiation emitted by the diffusing portion is diffused towards a user’s passage and approaching zone, the approaching user risking being blinded. In addition, with this solution, the diffusing portion - when lit - is excessively enhanced with respect to the zone to be lit.

[0010] . Although advantageous, this solution forms a homogeneous diffusing strip running along the shelf which can bother the user’s sight and which can be enhanced excessively with respect to the zone to be lit.

[0011] . Therefore, the need is felt in the industry to provide a linear lamp with an improvedreduction of the risk of blinding and simultaneously improved aesthetic features.

[0012] . Solution

[0013] . It is the object of the present invention to provide a linear lamp as well as a furnishing element comprising the linear lamp.

[0014] . This and other objects and advantages are achieved by a linear lamp according to claim 1 , as well as by a furnishing element according to claim 15.

[0015] . Other advantageous embodiments are the subject of the dependent claims.

[0016] . An analysis of this solution has shown how the suggested solution allows obtaining an increased reduction in the blinding of users approaching the lamp.

[0017] . Moreover, the suggested solution improves the aesthetic aspect of the lamp by introducing a striped diffusing pattern comprising portions in which the light radiation transmission is allowed in an attenuated manner and portions in which the light radiation transmission is prevented.

[0018] . In addition, the suggested solutions allow the linear lamp to be stably and reversibly connected in a respective groove, for example obtained in a portion of a furnishing element.

[0019] . Still further, by virtue of the suggested solutions, it is possible to ensure an improved lighting uniformity on the side opposite to the approaching direction of a user to the lamp.

[0030] . Description of some preferred embodiments

[0031] . According to a general embodiment, a linear lamp 1 is provided. The linear lamp 1 mainly extends along a longitudinal direction X-X. For example, the linear lamp 1 is an LED lamp. Linear means that the longitudinal direction X-X is the main dimension of the lamp with respect to the other dimensions in directions perpendicular to the longitudinal direction.

[0032] . The linear lamp 1 comprises a support profile 2. For example, the support profile 2 can be made of a metal material or a polymer material and can have a substantially U-shaped section. According to an embodiment, the support profile 2 is linear and extends mainly along the longitudinal direction X-X.

[0033] . Moreover, the linear lamp 1 comprises a plurality of light sources 3 configured to emit light radiation. The plurality of light sources 3 is arranged along the longitudinal direction X-X andsupported by or connected to the support profile 2. In an embodiment, the plurality of light sources 3 is a plurality of LEDs (light emitting diodes), e.g., a strip of LEDs or an array of LEDs distributed linearly along the longitudinal direction X-X. In an embodiment, the plurality of light sources 3 is connected to and / or arranged in contact with a heat sink 15, e.g., a metal plate, made in one piece with the support profile 2 or connected to the support profile 2, as shown in the drawings.

[0034] . The linear lamp 1 comprises a diffusing cover 4 configured to diffuse the light radiation emitted by the plurality of light sources 3. The diffusing cover 4 is connected and / or connectable to the support profile 2 so as to cover the plurality of light sources 3. In an embodiment, the support profile 2 and the diffusing cover 4 are made in one piece, forming a support and diffusion profile. In an embodiment, the diffusing cover is linear and extends mainly along the longitudinal direction X-X.

[0035] . A respective centerline axis M dividing the light source in half is defined in each lamp section of the linear lamp 1 perpendicular to the longitudinal direction X-X and passing through a light source of the plurality of light sources 3. In some embodiments, the centerline axis M can be determined as the median axis between the portions of the support profile 2 configured to support the plurality of light sources, or as the median axis dividing in half the heat sink 15 to which the plurality of light sources is connectable.

[0036] . The linear lamp 1 defines a midplane AM passing through each centerline axis M and through the longitudinal direction X-X, where the midplane AM divides the linear lamp 1 into a front zone and a rear zone with respect to an axial direction A-A perpendicular to midplane AM.

[0037] . The diffusing cover 4 comprises a first diffusing portion 5 configured to diffuse the light radiation emitted by the plurality of light sources 4 towards a zone to be lit. The first diffusing portion 5 extends in each lamp section at least along the axial direction A-A crossing the midplane AM between the rear zone and the front zone of lamp 1 .

[0038] . The diffusing cover 4 comprises a second diffusing portion 6 connected to the first diffusing portion 5, where the second diffusing portion 6 extends in the front zone of lamp 1 . In an embodiment, the second diffusing portion 6 extends only in the front zone of lamp 1 without being crossed or without crossing the midplane AM in the extension thereof.

[0039] . Advantageously, the lamp 1 and / or the diffusing cover 4 comprise an attenuation coating 7 configured to attenuate the light radiation diffused by the second diffusing portion 6 on the side opposite to the midplane AM.

[0040] . The attenuation coating 7 is connected to cover a surface of the second diffusing portion 6, preferably to cover the surface facing the side opposite to the midplane AM, for example, leaving the surface opposite to the second diffusing portion 6 free.

[0041] . Advantageously, the attenuation coating 7 has a striped pattern and comprises at least one diffusing strip 8 configured to diffuse the light radiation diffused by the second diffusing portion 6in an attenuated manner, and at least two shielding strips 8, 9 configured to prevent the diffusion of the light radiation from the second diffusing portion 6, where each diffusing strip 8 is interposed between two respective shielding strips 9, 10.

[0042] . In an embodiment, the number of shielding strips 9, 10 is equal to the number of diffusing strips 6 plus one. In an embodiment, from one to eight diffusing strips are provided.

[0043] . In an embodiment, each diffusing strip 8 and each shielding strip 9, 10 extends along directions parallel to the longitudinal direction X-X, e.g., straight. In an embodiment, each diffusing strip 8 and each shielding strip 9, 10 extends along a curvilinear direction, e.g., sinusoidal, with respect to the longitudinal direction X-X.

[0044] . By virtue of the striped pattern, it is possible to attenuate the light radiation output from the lamp and / or from the diffusing cover on the side opposite to the midplane AM of the lamp, on the one hand, avoiding or reducing the risk of blinding, and on the other, improving the aspect of the visible portion of the lamp which will have a lighting effect when turned ON with at least one lit strip enhanced by two dark strips which are not lit or have very low lighting.

[0045] . In an embodiment, the diffusing cover 4 and / or the first diffusing portion 5 and the second diffusing portion 6 are made of a first polymer material filled with diffusing particles, for example, by means of a first masterbatch color or other diffusing particles of the known type, so as to have a light radiation transmission between 10% and 80% in the visible spectrum.

[0046] . In an embodiment, the attenuation coating 7 is made of a second polymer material filled with diffusing particles, for example by means of a second masterbatch color or other diffusing particles of the known type, so as to have a light radiation transmission less than the light radiation transmission of the diffusing cover 4, preferably between 0% and 70% in the visible spectrum.

[0047] . For example, the light radiation transmission is measurable by means of visual diffused transmission densitometers.

[0048] . In an embodiment, the first polymer material is polycarbonate or polymethylmethacrylate. In an embodiment, the first polymer material and the second polymer material are the same polymer material. In an embodiment, the second polymer material is polycarbonate or polymethylmethacrylate.

[0049] . In an embodiment, the first masterbatch color is a light color, e.g., milk white or opal white. In an embodiment, the first masterbatch color is different from the second masterbatch color. In an embodiment, the second masterbatch color is a dark color, e.g., brown or black. The contrast between the diffusing strips and the shielding strips is also obtainable with other diffusing particles and with other colors that are not necessarily dark.

[0050] . In an embodiment, the attenuation coating 7 and the diffusing cover 4 are made by coextrusion, preferably where the longitudinal direction X-X is a straight direction.

[0051] . In an embodiment, each diffusing strip 8 has a smaller thickness than the thickness of each shielding strip 9, 10. In an alternative embodiment, each diffusing strip 8 has a lower diffusing particle concentration than the diffusing particle concentration of each shielding strip 9, 10.

[0052] . In an embodiment, each diffusing strip 8 has a thickness or a diffusing particle concentration so as to have a light radiation transmission less than 70%, preferably less than 50%, even more preferably between 10% and 70%.

[0053] . In an embodiment, each shielding strip 9, 10 has a thickness or a diffusing particle concentration so as to have a light radiation transmission less than 20%, preferably less than 10%, even more preferably between 0 and 5%.

[0054] . In an embodiment, each diffusing strip 8 has a thickness less than 0.4 mm, preferably between 0.1 and 0.3 mm, even more preferably between 0.2 mm and 0.3 mm.

[0055] . In an embodiment, each shielding strip 9, 10 has a thickness greater than or equal to 0.5 mm.

[0056] . In an embodiment, the first diffusing portion 5 is connected to the support profile 2 so as to directly face the plurality of light sources 3. In an embodiment, the second diffusing portion 6 is connected to the first diffusing portion 5 in a cantilevered manner, moving away from the support profile 2 in the front zone of lamp 1 , so as to avoid directly facing the plurality of light sources 3. In an embodiment, the second diffusing portion 6 is arranged downstream of the first diffusing portion 5 so as to diffuse the radiation diffused by the first diffusing portion 5. In an embodiment, the attenuation coating 7 is connected to cover the surface of the second diffusing portion 6 facing the side opposite to the midplane AM.

[0057] . The zone to be lit is thus illuminated in a uniform and improved manner by the light radiation diffused by the first diffusing portion 5 and by the light radiation diffused and reflected by the surface of the second diffusing portion 6 facing the midplane AM, while the light radiation transmitted in the direction opposite to the midplane AM is attenuated, forming the striped pattern created by the attenuation coating 7, thus reducing the risk of unattractive glaring and blinding and lighting in zones that are not to be lit.

[0058] . By leaving the surface of the second diffusing portion facing the midplane free of coating, it is thus possible to improve the lighting by virtue of a further diffusion of the light radiation on the side axially opposite to the second diffusing portion which is added to the radiation diffused by the first diffusing portion, thus improving lighting uniformity and homogeneity on the side opposite to a user’s passage or approaching zone, while simultaneously attenuating the lighting on the side of the user since the output light radiation is diffused three times through the passage of the first diffusing portion, the second diffusing portion, and through each diffusing strip.

[0059] . In an embodiment, the first diffusing portion 5 mainly extends along the longitudinaldirection X-X, and in said each lamp section, the first diffusing portion 5 is tilted by a first angle B with respect to the centerline axis M, where the first angle is between 60 degrees and 80 degrees, preferably between 74 degrees and 76 degrees. In an embodiment, the first diffusing portion 5 mainly extends along the longitudinal direction X-X, and in said each lamp section, the first diffusing portion 5 is tilted by an angle less than 30 degrees with respect to the axial direction A-A, preferably less than 20 degrees, preferably between 10 and 20 degrees.

[0060] . In an embodiment, the support profile 2 comprises a first support arm 11 and a second support arm 12. The first support arm 11 and the second support arm 12 are arranged in the rear zone and in the front zone of lamp 1 , respectively. In an embodiment, when connected to the plurality of light sources 3, the first support arm 11 and the second support arm 12 form a substantially U- shaped profile in said each lamp section. In an embodiment, the first support arm 11 and the second support arm 12 comprise a first coupling hand 16 and a second coupling hand 17, respectively, which are configured to couple and / or form connection seats or rails which are connected and connectable to the plurality of light sources 3 and / or the heat sink 15. The centerline axis M and the midplane AM can thus be determined by assessing the distance between the first coupling hand 16 and the second coupling hand 17. In an embodiment, the first support arm 11 is straight in the lamp section and perpendicular to the axial direction A-A. In an embodiment, the second support arm 12 in the lamp section extends forming a curved portion with concavity axially opposite to the first support arm 11 .

[0061] . In an embodiment, the first diffusing portion 5 in said each lamp section is connected to the first support arm 11 with a first end thereof and to the second support arm 12 with a second end thereof, where the first end is closer to the plurality of light sources 3 than the second end so that the radiation is diffused from the first diffusing portion mainly in the direction of the rear zone of lamp 1 and so that the first diffusing portion is at least partially arranged inside the support profile 2. In an embodiment, the second diffusing portion 6 extends from the second end of the first diffusing portion 5 in a cantilevered manner.

[0062] . By virtue of the provision of the inclination of the first diffusing portion 5, it is possible to direct the diffusion of the light radiation towards the zone to be lit, and it is also possible to partially insert the first diffusing portion into the support profile 2 and better conceal the first diffusing portion 5 from a user, which in turn is concealed in a cantilevered manner due to the second diffusing portion 6 covering the front zone of the lamp at least axially but also in tilted axial directions with respect to the midplane.

[0063] . Due to the provision of the inclination of the first diffusing portion 5, it is possible to eliminate the light source from a user’s field of view as much as possible.
