Definitions

• the invention relates to a lighting device comprising a support panel located between two outer sheets, which support panel is provided with at least one light emitting module, whilst at least one of the outer sheets is translucent, which outer sheets are movable with respect to each other at least from a folded state in which the support panel and the outer sheets extend substantially parallel to each other and an unfolded state in which the outer sheets are at least partly further spaced apart than in the folded state.
• Foldable lighting devices are in very widespread use in a multitude of fields.
• WO2009/147657A2 shows a foldable lampshade adaptable for inexpensive mass production and configured for easy assembly.
• the frame part comprises a pair of interconnected or separate complementary sheet-like parts, substantially shaped as a mirror image of each other.
• the sheet-like part is a sheet or foil, optionally having concave and/or convex relief shapes and/or notched curves as ornaments or folding aids.
• the lamp shade may be assembled and disassembled without removing the lamp socket with the lamp bulb.
• a general object of the present invention is to provide an improved foldable lighting device, in particular a lighting device that is easy to assemble.
• the invention provides a lighting device wherein in the folded state the two parallel longitudinal sides of a first of the two outer sheets are connected to the respective two parallel longitudinal sides of a second of the two outer sheets to form a first and second set of interconnected longitudinal sides, wherein the first and second sets of interconnected longitudinal sides are movable towards each other to space apart the outer sheets in the unfolded state.
• the first and second set of interconnected longitudinal sides are moved towards each other.
• the two outer sheets will curve outwardly allowing them to become at least partly spaced apart from the support panel.
• the result of the movement and curvature is a lighting device having a tube-like shape.
• the lighting device In the folded state the lighting device is relative flat and therefore takes up very little space and is easy to store and to transport. Since the support panel is located between the outer sheets, both in the folded and unfolded state, the light emitting modules on the support panel are always protected against damages and pollution by the outer sheets.
• the outer sheets In the folded state the outer sheets can have a width that is larger than the width of the support panel. In the unfolded state the distance between the longitudinal sides of the outer sheets is smaller than in the folded state. This allows the outer sheets to get curved.
• the invention provides a lighting device wherein at least in the unfolded state, the two sets of interconnected longitudinal sides of the outer sheets comprise a mount for the support panel.
• the outer sheets In the unfolded state the outer sheets can be curved in such a way that the connected parallel longitudinal sides of the outer sheets are at a distance with regard to each other that is approximately the same as the width of the support panel.
• the curved outer sheets are mounted under an angle with respect to each other in the region of the connected parallel longitudinal sides.
• the support panel can then be held by the respective angles formed by the two outer sheets on both parallel longitudinal sides.
• the support panel is in the unfolded state stuck between the connected parallel longitudinal sides. In the ideal situation there will be no play between the support panel and the connected parallel longitudinal sides, so that the support panel is firmly held in place and is unable to move in directions parallel to the support panel.
• the support panel can be fastened to either one of the outer sheets by means of fastening means to prevent the support panel from moving in the longitudinal direction.
• the support panel is fastened to both outer sheets, the constructional integrity of the lighting device is guaranteed, as in the unfolded state the fastened support sheet prevents the curved outer sheets from returning to their folded state.
• the interconnected parallel longitudinal sides can comprise protrusions, i.e. folded edges, that form a mount for the support panel.
• the invention provides a lighting device wherein at least one of the outer sheets comprises a flap being foldable about a fold line that extends between the two parallel longitudinal sides.
• the flap is foldable between a folded flat state and an unfolded state in which the flap is folded through a certain angle over the fold line, thus at least partly covering the transverse side of the lighting device.
• the invention provides a lighting device wherein the fold line is arc-shaped, the convex side of the arc-shaped fold line being located outside the flap.
• the arc-shaped fold line is advantageous since the outer sheets have a curved shape in the unfolded state.
• the fold line will define the curvature of the outer sheet to which it is attached.
• the invention provides a lighting device wherein the flap is delimited by the arc-shaped fold line on one side of the flap and an arc-shaped edge on the opposite side of the flap.
• an opening on the transverse side of the lighting device will have a cross section that is curved on both outer sheet sides.
• the flap will be able to cover the entire opening.
• the flap is preferably folded through approximately 90 degrees and extends therefore substantially perpendicularly to the support panel.
• the flap is curved in such a way that the arc-shaped edge of the flap of one outer sheet is adjacent to the curved edge of the other outer sheet.
• the invention provides a lighting device wherein in the unfolded state the outer sheets are held spaced apart by the folded flap.
• the folded flap In order for the outer sheets to remain in a curved state, the folded flap provides a blocking means preventing the outer sheets to return to the folded state. To this end the arc-shaped edge of the flap of one outer sheet is adjacent to the curved edge of the other outer sheet.
• both outer sheets are provided with flaps on both sides, wherein the flaps near one side of the two outer sheets extend parallel to each other, wherein the arc- shaped fold line of one outer sheet is located near the arc-shaped edge of the other outer sheet.
• the invention provides a lighting device wherein one of the outer sheets is reflective, whilst in the unfolded state light emitted by the light emitting module towards the reflective outer sheet is reflected by the reflective outer sheet towards the translucent outer sheet through the support panel.
• the light emitting module can be any form of light emitting module, such as a conventional light bulb, a neon light or the like, but is preferably a light emitting diode (LED), that produces light having a very high intensity and that has a relative low power
• LED light emitting diode
• the light emitting modules are preferably mounted only on the side of the support panel facing the reflective outer sheet.
• the reflective outer sheet has reflective properties in the direction facing the at least one light emitting module.
• the reflective outer sheet is highly reflective to reflect light to a maximum extent.
• the reflective outer sheet can for example be a MCPET sheet or an aluminium sheet.
• the translucent outer sheet is a sheet that allows the light to pass from the inside of the lighting device to the outside of the lighting device.
• the translucent outer sheet is mounted on the side of the support panel facing away from the at least one light emitting module.
• the translucent outer sheet can be a plastic sheet.
• the support panel comprises the at least one light emitting module and can comprise also the electric power supply lines that are needed to supply the at least one light emitting module with electric power.
• More than one light emitting modules can be mounted on the support panel. To this end an array of interconnected light emitting modules can be formed.
• a light ray that is emitted by the at least one light emitting module will travel towards the reflective outer sheet.
• the reflective outer sheet will reflect the light ray through the support panel, in the direction of the translucent outer sheet and through the translucent outer sheet towards the outside of the lighting device.
• a curved reflective outer sheet allows the light to be reflected in different directions as the angles of incoming and outgoing light rays vary at each point of the curved reflective outer sheet.
• a curved translucent outer sheet provides the necessary space with the support panel to prevent spotty shadows on the translucent outer sheet.
• the distance between the LEDs on the support panel is preferably less than the distance between the LED's and the translucent outer sheet to obtain a uniform light distribution over the translucent outer sheet. Since the light is first directed towards the reflective outer sheet and then back through the support panel towards the translucent outer sheet, the distance between the two outer sheets can be about 2/3 of the distance which would be needed if the light were directed directly from the support panel to the translucent outer sheet to obtain the same length of a light path.
• the invention provides a lighting device wherein the support panel is at least partly translucent.
• the support panel has an open structure, allowing light to pass through the support panel.
• the light that is reflected by the reflective outer sheet will pass through the support panel on which the light emitting modules and the electric power supply lines are mounted.
• the support panel can comprise translucent parts, such as for example a base panel made out of a transparent plastic.
• the support panel can be formed as a wire grid onto which light emitting modules are mounted. The areas that are not covered with wires or light emitting modules can be open areas. No base panel has to be provided in those areas as the constructional strength of the support panel can be provided by the wire grid.
• the invention provides a lighting device wherein the translucent outer sheet is a light diffuser.
• the light diffuser can be a translucent plastic sheet having a certain surface roughness.
• the surface roughness breaks up a light ray that passes through the light diffuser and disperses the light in multiple directions.
• the use of a diffuser has the advantage that light of a relatively high intensity is spread out in multiple directions, thus reducing the relative intensity of the light in one specific direction. Glare, that is caused by high intensity light rays in a specific direction, is thus further reduced to a large extent.
• the diffuser serving as a translucent outer sheet will disperse the light and provide an even distribution of light to the user and thus make up for the shadow. To this end the diffuser needs to be spaced apart from the support panel.
• the diffuser sheet is preferably a PET or PC film having a surface roughness.
• the invention provides a lighting device wherein the reflective outer sheet is opaque.
• An opaque reflective outer sheet prevents light from passing through the reflective outer sheet. As the reflective outer sheet reflects all the light that hits the reflective sheet, the loss of light is minimized and the light output through the translucent outer sheet is maximized.
• the invention provides a lighting device wherein, the interconnected longitudinal sides of the outer sheets are connected to each other by fastening means.
• the fastening means can comprise for example clips, rings or adhesive tape.
• the fastening means allow tilting of a region near the longitudinal side of one of the outer sheet with respect to a region near the longitudinal side of the other outer sheet to unfold the lighting device.
