Description

  The present invention relates to an LED lighting fixture that is used as a lighting fixture by replacing a fluorescent lamp of a fluorescent lighting fixture mounted on a ceiling with an LED lighting tube, for example.

  Recently, LEDs with an extremely low power consumption have been developed, and long-life LEDs have been developed. However, use of these LEDs instead of long fluorescent lamps has been accelerated. As shown in FIG. 2, the LED lighting tube is formed by inserting and arranging an LED base 28 in which a necessary number of LEDs are arranged on a long and flat base in a transparent circular pipe LED lighting pipe 24, and supplying electric power thereto. Illuminate.

  Structurally, the long fluorescent lamp 23 arranged on the reflector 22 of the conventional mountain-shaped mounting base 21 of FIG. 1 is removed, and the LED illumination tube 24 shown in FIG. is there. 25 is a base, 26 is a terminal, and 27 is a socket.

  The positional correlation between the terminal 26, the socket 29 of the socket 27 and the LED base 28 is such that a straight line connecting the two terminals 26 is arranged in parallel with the LED base 28 as shown in FIG. Accordingly, when the terminal 26 is inserted into the floating hole 29, the LED base 28 is parallel to the reflecting plate 22, and the light reflected by the reflecting plate 22 is wide (on the right side in the drawing) and is not distributed outside at a wide angle. .

  In this case, the LED substrate 28 blocks the light from the LED disposed on the upper surface from the lower side, so that the light distribution in the lateral direction is further reduced. In the lighting device using two LED boards 28, the two LED lighting tubes 24 are sufficiently bright in the vicinity of the LED lighting tubes 24 arranged side by side, so that the light distribution to the outside of the left and right LED lighting tubes 24 is achieved. It must be sufficient.

Japanese Patent Application Laid-Open No. 2004-133867 does not include a description that takes the above into consideration, and does not disclose it in other things.
JP 2008-66043 A

  The problem to be solved by the present invention is that a wide illumination range is ensured by widening the light distribution of the LED lighting tube of the lighting device having the mountain-shaped reflecting plate toward the outside.

  The present invention comprises a circular long LED lighting tube, a long LED base disposed inside the lighting tube, and two terminals provided at an end of the lighting tube, and the LED lighting. A straight line connecting the two terminals and the LED base are arranged non-parallel in the axial cross-sectional direction of the tube.

  According to the first aspect of the present invention, since the LED base is arranged non-parallel to the reflecting plate, it is possible to provide an LED lighting apparatus capable of realizing a wide range of light distribution.

  An object of the present invention is to provide an LED lighting device that brightens the surroundings by widening the light distribution of the outside illumination when the LED lighting device, particularly, two LED lighting tubes are used.

  The present invention comprises a circular long LED lighting tube, a long LED base disposed inside the lighting tube, and two terminals provided at an end of the lighting tube, and the LED lighting. The object was achieved by arranging the straight line connecting the two terminals and the LED base in a non-parallel manner in the axial cross-sectional direction of the tube.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. FIG. 4 shows the LED lighting device as viewed from the end. Therefore, the socket and the end of the LED lighting tube appear, and the arrangement relationship thereof is schematically shown.

  Reference numeral 1 denotes a mounting base which is a conventional base in which the reflectors 2 and 3 are combined in a mountain shape. Reference numerals 41 and 42 are conventional sockets provided at both ends of the mounting base 1, and the sockets 41 and 42 have two receptacles 51, 52 and 53, 54 per socket 41 and 42. The straight lines connecting the two pairs of receiving ports 51, 52 and 53, 54 are set in parallel with the inclination of the reflecting plates 2 and 3.

  The terminals 51, 52, 53, 54 arranged in this way correspond to the terminals 81, 82, 91, 92 of the LED lighting tubes 6, 7 in position. The LED illumination tubes 6 and 7 have LED bases 11 and 12 arranged so that a large number of LEDs 10 can illuminate. And the space | interval of the receptacles 51 and 52 and the positional interval of the terminals 81 and 82 correspond, and it has the structure where the terminals 81 and 82 can be electrically and mechanically connected to the receptacles 51 and 52. In this case, the corresponding intervals between the receiving ports 53 and 54 and the terminals 91 and 92 are the same.

  The straight lines connecting the respective terminals 81, 82 and 83, 84 with respect to the horizontal position of the LED boards 11, 12 are set so as to open outward. That is, the straight line connecting each of the terminals 81, 82 and 83, 84 is parallel to the straight line connecting the receiving ports 51, 52 and 53, 54, and this parallel relationship also corresponds to the reflectors 2 and 3.

  That is, since the LED bases 11 and 12 are provided with the LED 10 elements on the upper surface, the LED bases 11 and 12 become brighter on the upper surfaces of the LED bases 11 and 12. The light distribution is reduced by being blocked by 12. Accordingly, the LED substrate 11 is made non-parallel to the straight line connecting the terminals 81, 82 and 91, 92 when viewed from the end, so that the wide angle is obtained due to the relationship between the LED substrates 11, 12 and the reflectors 2, 3 with respect to the outside. The light distribution to the outside can be widened.

  Here, the case where the LED lighting tube 6 is attached to the socket 41 on the right side of FIG. 4 will be described. The straight line connecting the receiving ports 51 and 52 of the socket 41 originally coincides (parallel) with the inclination of the reflecting plate 2. When the terminals 81 and 82 of the lower LED lighting tube 6 are mechanically and electrically coupled to the openings 51 and 52, the straight line connecting the LED base 11 and the terminals 81 and 82 of the LED lighting tube 6 is not parallel (the outer side is As shown by the dotted line in the figure, the relationship between the reflector 2 and the LED base 11 becomes wide at the outside (right side in the figure), and therefore, the right side of the reflector 2 increases the amount of light. It will be possible to distribute light. Similar effects can be obtained on the left side of FIG.

  In this embodiment, when the LED lighting tubes 6 and 7 are attached to the sockets 41 and 42, it is necessary to distinguish between the right side and the left side.

  INDUSTRIAL APPLICABILITY The present invention is useful when exchanging a fluorescent lamp of a lighting fixture provided with a mountain-shaped reflector with an LED lighting tube, and has a particularly low power consumption and a long durability. It can realize light distribution and is industrially effective.
