Description

    Field of the invention
  • The invention relates to a LED-based lighting component and to an assembly method of such a component. It specifically relates to a reflector mounted to a printed circuit board holding LEDs.
    • Description of the related art
  • LED lighting systems offer significant advantages over traditional incandescent, HID and fluorescent lamps. LEDs are of smaller size, offer higher reliability, longer operational life and lower energy consumption. However, there are specific requirements when using LEDs. As increased operating temperature significantly reduces lifetime, cooling is of high importance. Furthermore, most LED chips are approximately isotropic light sources with a lambertian light distribution, which must be adapted to specific requirements of a lighting system.
  • The US patent application publication 2008/027894181 A1 discloses a printed circuit board with LEDs soldered thereon. For adapting the light distribution, injection molded reflectors are positioned above each individual LED. The disadvantage is that the reflectors must be manually assembled to the printed circuit board. This is a complex and time-consuming step. Furthermore, the reflectors are comparatively complex and expensive. Changing of light distribution requires modifying the reflectors, including redesigning, making new tools and producing new reflectors.
    • Summary of the invention
  • The problem to be solved by the invention is to provide means for cooling and adapting the light distribution of LEDs mounted to a carrier like a printed circuit board.
  • Solutions of the problem are described in the independent claims. The dependent claims relate to further improvements of the invention.
  • A preferred embodiment relates to a LED-based lighting component comprising a strip shaped printed circuit board and a plurality of LEDs mounted thereon. Preferably, a reflector strip is placed on the printed circuit board. The reflector strip is of sheet metal with punched reflectors. The reflectors extend over the surface of the printed circuit board. They guide the light of the LED chips, which often have an approximated lambertian light distribution. The reflector strip can easily be manufactured from sheet metal by a simple process of punching and bending the reflectors of the main plane, which is defined by the metal sheet. This allows for a precise and inexpensive manufacturing process of high volumes of the reflector strip. The reflector strip may comprise reflectors for any number of LEDs.
  • Furthermore, the reflector strip preferably has guides for aligning the reflector strip to the printed circuit board. During assembly, the guides are positioned within holes of the printed circuit board. Alignment of the reflector strip in relation to the LEDs by means of the guides is an easy procedure, as the reflector strip simply has to be placed on the printed circuit board and the to be moved over the surface of the printed circuit board until the guides snap into the holes of the printed circuit board. This further prevents damaging of LEDs or other electronic components on the printed circuit board by touching these with the reflector strip.
  • There are various methods for firmly attaching the reflector strip to the printed circuit board. For example, the guides may be bent back from the rear side of the printed circuit board to hold the reflector strip down to the printed circuit board. The reflector strip may also be glued or soldered to the printed circuit board. It is preferred to insert the printed circuit board together with the reflector strip into a frame. For this purpose, the frame may have one or two braces. The frame may also serve as mechanical support, a heat sink or as an insulator of the assembly. The frame may be a strand casted, pultruded or extruded profile. It preferably has overhangs to hold the reflector strip down to the printed circuit board and further to fix the reflector strip and the printed circuit board within the frame. To improve the fixation within the frame, the reflector strip may have springs. These assert a predetermined force to the reflector strip. For easy assembly the printed circuit board with attached reflector strip is pushed into an opening at the end of the profile. Slipping of the printed circuit board within the profile may be prevented by end caps or by a lug or a screw.
  • According to a further preferred embodiment, a reflector strip comprises at least one reflector. The reflector strip is preferably made of metal, which may be aluminum or brass, or any other material, which has a light reflecting surface. Most preferably the reflector strip is a metal sheet and the at least one reflector is punched from this metal sheet. The at least one reflector may be part of the surface of the reflector strip which is bent into an angle from a main plane of the reflector strip.
  • It is further preferred, if the reflector strip has at least one blanking or opening for the at least one LED, thus surrounding the LED on the printed circuit board. The reflector strip may have further blankings leaving space for further electronic components on the printed circuit board. The reflector strip may further have at least one guide for precisely locating the reflector strip in relation to the printed circuit board. Furthermore, the reflector strip may have at least one spring and/or an elastic element for pressing the reflector strip to the printed circuit board.
  • Preferably, the reflector strip is placed on a printed circuit board, the printed circuit board holding at least one LED, preferably a plurality of LEDs in predetermined distances. Most preferably these predetermined distances are constant.
  • In a further embodiment, a frame may be provided for fastening the reflector strip to the printed circuit board. The frame may furthermore act as at least one of a mechanical support, a heat sink, an insulator. Preferably, the frame is a profile, which may be manufactured by strand casting, pultrusion or extrusion. The frame is preferably made of metal or ceramics, most preferably of aluminum.
  • In a preferred embodiment, the reflector strip has a first reflector and a second reflector, being located at opposing sides of a LED. In another embodiment, the reflector strip has four reflectors being located at or four sides of a rectangular LED. There may be any other number or any other shape of the reflectors.
  • Although it is preferred, that the reflectors reflect light from the LED into a different direction than it was emitted from the LED, the reflectors may also and/or alternatively shade light from the LED, thus preventing light radiating into unwanted directions.
  • In a further embodiment, the reflector strip may be mounted at the opposite side of the LEDs of the printed circuit board. In this case, the printed circuit board may have at least one opening or slot, through which the individual reflectors can penetrate the printed circuit board.
  • Mounting the strip to the printed circuit board is a very simple procedure. The first step the reflector strip is positioned on the printed circuit board. Alignment may be simplified by inserting at least one bent guide of the strip into at least one hole of the printed circuit board. In the next step, the strip and the printed circuit board are inserted into the frame by pushing them into a slot opening at one end of the frame. The frame may further support alignment of the strip and the printed circuit board. By means of a flat spring, the printed circuit board and the strip are held in a predetermined position relative to the frame.
  • This arrangement results in a defined pressure of the printed circuit board (PCB) to the frame without any additional elements (e.g. screws, glue...). Due to the permanent elastic deformation of the flat spring, the thermal resistance between the PCB and the frame will not change over lifetime.
  • A further advantage of the embodiment is that the light distribution can easily be adapted to individual needs by simply changing the angle between a reflector and the reflector strip. This can even be done manually in a fine adjusting procedure after assembly. It is not necessary to manufacture a different strip for each modified reflector setting.
