Description

  • The present invention relates to a LED lamp, comprising a tubular housing which on the inside is provided with a plate, partly or completely extending in the longitudinal direction of the housing , the plate being provided with LEDS, and the housing further at the side of the LEDS being formed by a window extending, partly or completely, in the longitudinal direction of the housing for the transmission of the light of the LEDS outwards of the housing, with at least at one end of the housing a pin holder which is provided with openings for the lead-through of a pair of connecting pins, which connecting pins each with one outer end protrude outwards and by means of which outer ends the lamp can be fastened in an armature and can be connected to a power supply, while the connecting pins with their other outer end inside the housing are connected to a wiring for the power supply of the LEDS.
  • Such a LED lamp is known and is also referred to as LED strip-light. The known lamp can be placed into a strip-light armature or tube holder, which is adapted to that end, instead of a regular strip-light.
  • The known strip-light and also the known LED strip-light is provided with two connecting pins that are fixedly connected to the tube. Because of this the lamp can not be rotated when it is placed in an armature. With a strip-light this rotating is not necessary because it emits light all round. The aligning of the light of a strip-light takes place by application of a reflector.
  • Other than with the strip-light the known LED strip-light only emits light from the side where the LEDS are provided. It is known to make this light broad-beaming or far-beaming by a special plastic screening.
  • The known LED strip-light has the drawback , that when it is placed into the strip-light armature the light is aligned only downwards, and cannot be aligned to for instance the side.
  • The invention aims to obviate this drawback of the known LED lamp.
  • The LED lamp according to the invention to that end is characterized in that it is provided with means by which the housing, when the lamp is placed in the armature, is rotatable around its longitudinal axis, in such a way that, by rotating, the window can be directed to a place or object that is to illuminated.

  • According to a further characteristic of the LED lamp according to the invention the pin holder is formed by a first tubular part which at one outer end is provided with a covering in which openings for the lead-through of the connecting pins are provided and which at the other outer end at an edge connects to a second tubular part provided in an even line with the first tubular part, in which the second tubular part has an outer diameter which is smaller than the inside diameter of the outer end of the housing, in such a way that the second tubular part can be inserted into the outer end of the housing and is rotatable therein, while the first tubular part has an outer diameter that is larger that the inside diameter of the outer end of the housing, in such a way that at its edge it rests upon the outer end of the housing.
  • According to another characteristic of the LED lamp according to the invention the pin holder is provided with connecting means adapted to co-operate with counter connecting means forming part of the outer end of the housing for a rotatable connection of the pin holder to the housing.
  • According to another characteristic of the LED lamp according to the invention the means are formed by one or more feet provided at or around the second tubular part with radially extending protrusions that can hook behind a ring provided around the inner circumference of the outer end of the housing.
  • According to a further characteristic of the LED lamp according to the invention it is provided with means by which the path of rotation of the second tubular part in the outer end of the housing is limited, whereby the outer end of the housing, according to a further characteristic, is provided with a thickening extending along a part of the inner circumference, while the first tubular part is provided with a cam, whereby the path of rotation of the second tubular part in the outer end of the housing is limited by the stop of the cam against the thickening.
  • The invention further aims to provide an armature suitable for receiving the housing of a LED strip-light, which armature is formed by a holder with one or more holder parts for receiving the connecting pins of the lamp, characterized in that the armature is provided with means by which the lamp, when it is placed in the armature, can be rotated around its longitudinal axis, in such a way that, by rotating, the window can be directed to a place or object that is to illuminated.
  • According to a characteristic of the armature according to the invention the holder parts are formed by a first holder part that is fixedly connected to the holder, or forms part of it, and a second holder part that is rotatably mounted to the first holder part.
  • The invention will now be described further with reference to the drawings of an example of an embodiment of the LED lamp according to the invention.
    • Figure 1 shows a perspective view of a LED strip-light according to the invention.
    • Figure 2 shows a cross-section of the LED lamp according to figure 1.
    • Figure 3 shows a perspective view of an outer end of the housing of the LED lamp.
    • Figure 4a shows a perspective view of a pin holder according to the invention, in this example of an embodiment comprised of two parts, and an outer end of the housing of the lamp, in which these are taken apart.
    • Figure 4b shows a perspective view according to figure 4a, in which the two parts of the pin holder are joined together.
    • Figure 4c shows a perspective view according to figures 4a and 4b, in which the pin holder is placed in the outer end of the housing of the lamp.
  • As is shown in figures 1 and 2 the LED strip-light 1 comprises a tubular housing 2 which on the inside is provided with a plate extending in the longitudinal direction of the housing 2, the plate being provided with LEDS 3 (figure 2), and the housing further at the side of the LEDS 3 being formed by a window 4 extending in the longitudinal direction of the housing 2 for the transmission of the light of the LEDS outwards of the housing 2. As is shown in figure 1, a pin holder 6 is provided at the outer end 5 of the housing 2 which is provided with openings 7 for the lead-through of a pair of connecting pins 8. The connecting pins each with one outer end 9 protrude outwards. By means of these outer ends 9 the lamp 1 can be fastened in an armature and be connected to a power supply.
  • As is further shown in the figures 4a, 4b and 4c, the connecting pins 8 with their other outer end 10 are connected inside the housing 2 to a wiring 11 for the power supply of the LEDS.
  • When the pin holder 6 is placed in the outer end 5 of the housing 2 (figure 1 and figure 4c) this is rotatable in the housing 2.
  • As can be seen in figure 1 and 4b the pin holder 6 is formed by a first tubular part 12 which at one outer end 13 is provided with a covering 14 in which the openings 7 for the lead-through of the connecting pins 8 are provided. At the other outer end 15 the tubular part 12 connects at an edge 16 to a second tubular part 17 provided in an even line with the first tubular part 12. As can be seen in the figures 1, 4b and 4c the second tubular part 17 has an outer diameter which is smaller than the inside diameter of the outer end 5 of the housing 2, in such a way that the second tubular part 17 can be inserted into the outer end 5 of the housing 2 and is rotatable therein (figure 1 and 4c). The first tubular part 12 has an outer diameter that is larger than the inside diameter of the outer end 5 of the housing 2, in such a way that at its edge 16 it rests upon the outer end 5 of the housing 2.
  • In the shown example of the embodiment of the LED lamp according to the invention feet 18 are provided around the second tubular part 17 with radially extending protrusions that can hook behind a ring 19 provided around the inner circumference of the outer end 5 of the housing, such as can be seen in figure 4c, and by means of which the pin holder 6 can be fixedly, but still rotatably, clamped in the housing 2. In the shown example of an embodiment the ring 19 is provided with a toothing 20. With the help of this toothing by means of the feet 17 the pin holder 6 can to a certain extent be fixed against rotation relative to the housing, in such a way that, in order to rotate the pin holder relative to the housing a certain amount of pressure has to applied.
  • In order to prevent the pin holder 6 from rotating unlimited relative to the housing 2, as a result of which the wiring 11 between the connecting pins 8 provided in the pin holder 6 and the LEDS might be torn loose, means are provided by which the path of rotation of the second tubular part 17 in the outer end 5 of the housing 2 is limited. As can be seen in figure 2, to that end the outer end 5 of the housing 2 is provided with a thickening 21 extending along a part of the inner circumference, while the first tubular part (see figure 4a and 4b) is provided with a cam 22. The second tubular part 17 is to be placed into the outer end 5 of the housing in such a way that the cam 22 is received in the section A, therefore outside the area of the thickening 21 in the outer end 5 of the housing 2. The second tubular part 17 of the pin holder 6 with the cam 22 can make a to and fro rotating movement in the section A, and by means of which the position of the housing of the lamp can be adjusted.
