Definitions

  • the present disclosure relates to a light strip, in particular an elongated flexible light strip comprising a plurality of light sources.
  • Illuminating objects and/or spaces by means of elongated lighting arrangements is known.
  • EP 1 756 471 discloses an elongated flexible lighting system which comprises an array of light sources that are illuminated by electric power. It further comprises an elongated translucent extrusion of flexible material.
  • the array of light sources is integral to the extrusion with said extrusion transmitting and dispersing the light from the array such that the lighting system gives the appearance that the array of light sources is a continuous light source.
  • the conducting element is manufactured from an essentially flat conductor part, such as a band a strip or the like, into which there has been attached electric components, such as probes, LEDs, resistors and/or the like by arranging the same, preferably throughout built-in when viewed in a cross section with a casing material forming the said casing part, by exploiting a continuous manufacturing process, such as extrusion or the like.
  • the document also relates to a conducting element to be manufactured by the method.
  • the conducting element is a thin ribbon which is stored on rolls and which is particularly designed for building into a vinyl floor.
  • thermoplastic extrusion material completely encapsulates the first and second bus elements and the LED and urges the first and second bus elements and the LED into operative contact. To provide a robust light strip the thermoplastic extrusion material must harden, losing its flexibility.
  • the flexible light strip of claim 1 is provided.
  • the light strip including housing, being a flexible object facilitates handling and storage, e.g. coiled and/or bundled, and facilitates arranging a plurality of light sources along an object and adaptation of the light strip to a substrate to which it is to be mounted.
  • the light sources emitting substantially normal to the circuit board facilitates manufacturing and/or mounting the light strip, in that the emission direction of the light sources is readily discernible and in that light may be emitted radially from around bends with small radii.
  • Arranging the first and second portions such that the emitted light is reflected off the second portion allows providing illumination to desired directions other than normal to the circuit board, while retaining, e.g., the above-described beneficial mounting and/or handling properties. This significantly increases the number of possible locations and uses for the light strip.
  • the first and second portions are arranged so that the individual light sources are not directly visible, such that the emitted light or light cones are visible, but the light sources themselves and related objects are obscured from direct vision.
  • the first and second portions of the housing may generally have different optical properties, e.g. different refractive index, reflective index and/or transmittance for one or more wavelengths of the light emitted by the light sources, so as to provide desired illumination effects.
  • the housing is provided via moulding and/or extrusion techniques. This allows manufacturing light strips substantially uninterrupted for tens to hundreds of meters on end at substantially continuous properties and at a substantially constant quality.
  • the first and second portions may be co-moulded and/or co-extruded during such manufacturing process.
  • Suitable materials for the flexible circuit board comprise (strips of) insulating plastics materials such as nylon, kapton, mylar, etc.
  • Suitable materials for the housing comprise resilient plastics such as polyurethane, polyvinylchloride, PET, silicone rubber, etc, as well as mixtures thereof.
  • Claims 2 and 3 define light strips with particularly useful light emission intensity distributions.
  • the flexible light strip of claim 4 is provided.
  • the flexible printed circuit board, the plurality of light sources and the housing allow to provide an illumination arrangement with a plurality of light sources along an object which is shielded from outside influences, e.g. protected against bad weather.
  • the light strip comprising second electrical conductors allows providing operational security to the device. Further, the second electrical conductors may be manufactured in different manners than via printed circuit techniques which reduces costs. In particular when the second electrical conductors are manufactured as electric cables, e.g. copper wires and/or strands, their electrical resistance is significantly reduced compared to conductors manufactured with printed circuit techniques.
  • the flexible light strip of claim 4 allows powering an elongated flexible light strip with a power source connected on one side of the light strip and delivering electrical power to light sources remote from the position of the connection of the power source since electrical losses in the printed circuit board are counteracted by the parallel second conductors which suffer less to substantially no losses.
  • Interconnecting the first and second conductors on plural positions allows powering light sources from opposite sides which may result in a substantially constant optical output power of the light sources of the section concerned. This allows providing longer light strips with sufficient optical intensity without requiring additional power connections and/or interruptions than in the case of single-sided powering.
  • the second electrical conductors may be most easily connected to the flexible printed circuit board one or more connection portions between printed circuit board sections. This obviates further connection portions.
  • the second conductors in particular when in the form of metallic wires or cables, provide increased mechanical robustness to the light strip, in particular by decreasing variations of mechanical properties of the light strip. This assists preventing localisation of stress and related damage and it also facilitates handling and storage.
  • the housing material of a flexible light strip advantageously closely follows the contours of the circuit board, the light sources, and any further objects associated therewith so as to provide the light strip as an integral whole.
  • the outside shape of the light strip may be substantially constant, providing a pleasing appearance and facilitating mounting and handling.
  • the light strip is a substantially massive object, having substantially no cavities, so as to have increased robustness against vandalism and/or deformation under pressure of mounting arrangements and/or loads. Resistance to deformation further provides increased reliability of the illumination pattern to be provided by the flexible light strip.
  • an assembly according to claim 10 is provided. This facilitates interconnecting first and second conductors, thus reducing power losses along circuit board sections.
  • the assembly according to claim 11 facilitates interconnecting plural light strips, with improved power delivery per light strip.
  • the light strip 1 further comprises second conductors 6 extending underneath and in parallel to the flexible printed circuit board 2 along the length D of the light strip 1.
  • the first and second portions 7, 8 are formed around the circuit board 2 with any object arranged on it such that an object is formed which is closely encapsulated by the material(s) forming the housing 4 and such that an integrated and substantially massive object is formed, which is still flexible at least in the LH direction, preferably also in the WL direction and allowing helical (or cork-screw like) bending.
  • the light strip 1 is mountable onto a substrate with a bottom side (surface at negative H side) and due to its flexibility it can follow curves and bends of the substrate with the emission direction of the light sources 3 facing locally outward from the substrate (in the direction of the local normal, along H).
  • the first and second portions of the housing 7, 8 are arranged such that the light emitted by the light sources 3 is reflected off the second portion 8 to produce an illumination pattern with increased intensity in a direction substantially normal to the flexible printed circuit board 2.
  • the first and second conductors may be configured for powering a portion or all light sources 3 in series or in parallel. Parallel connection is preferred since it reduces the possible effect of one or more defect individual light sources 3.
  • a set of two conductors (+ and -) powered by DC power may suffice.
  • different conductors, control electronics and/or control cables may be provided. E.g. when using red, green and blue light LEDs a set of four connections may be used: one connection for each colour and a common ground connection. This may be provided with fourfirst conductors and four second conductors (e.g. see Figs 1A-2B , 5 and 6 ). Further conductors for further options and/or controls are also possible.
  • the circuit board 2 may be coloured and/or made reflective.
  • the housing may comprise one or more strips, films, and/or coating layers, etc, possibly integrated with a strip, film, coating, etc, on the circuit board 2, which may correspond to the colour of the substrate and/or be diffusely reflective, to reduce visibility of the light strip when the light level of the light sources is below environmental light or the light sources are off (i.e. not lit).
