Description

  The present invention relates to a straight tube LED lamp using an LED (light emitting diode) as a light source.

In recent years, LED lamps using LED elements excellent in power saving as light sources have been actively used due to increasing environmental awareness. Particularly recently, straight-tube LED lamps that can be replaced as they are in lighting apparatuses using fluorescent lamps are rapidly spreading.
In general, straight tube fluorescent lamps are used for indoor lighting and lighting for signs and vending machines, but LED lamps emit light unlike conventional fluorescent lamps that emit light in all directions. Since the direction of the light of the diode is directional, the angle of the illumination direction must be adjusted to an optimal angle, especially in signboards and vending machines. However, there is a problem in that the base portion is fixed and the structure is not easily adjustable.

  In view of such a problem, for example, in Patent Document 1, when a straight tube type LED lamp is mounted on a socket that is fixedly mounted, for example, a socket that is mounted in advance to mount a fluorescent lamp, the direction of the base is changed. There has been a proposal that the angle of the illumination direction can be adjusted to an optimum angle by changing the direction of the light emitting unit body through rotation without rotation.

JP 2009-266432 A

The lighting fixture described in Patent Document 1 can be formed into a straight-tube fluorescent lamp shape by covering the LED light emitters implanted on the mounting substrate with respective covers and forming the entire shape into a cylindrical shape, As a result, a lighting device can be provided as an alternative to fluorescent lamps. Furthermore, it is attached to the socket via the terminals provided at both ends of the light emitting unit main body, and has a structure that rotatably supports the light emitting unit main body containing the LED light emitting body in a state where the setting is completed, and is implanted on the surface of the mounting substrate. Even under the condition that the illumination light is specified in a certain direction, the irradiation direction can be arbitrarily changed through the rotation. Therefore, it is possible to freely select the irradiation direction and use it as an illuminating device that is the same as a fluorescent lamp, and it is stable because the rotation range and further the rotation position can be determined and kept at a fixed position. Lighting can be obtained, and it can be effectively used as lighting for signboards and lighting equipment for products in vending machines.
In addition, in the lighting fixture described in Patent Document 1, the locking piece 12 of the spacer 11 is engaged with the groove of the two cooling fins 7 in the groove of the cooling fin 7, and the screw formed on the spacer 11. A mounting seat 18 is fixed to the receiving hole 34 with a set screw 32, and a terminal cover is attached to the mounting seat 18 via a locking holder 20.

  In the illumination device incorporating the LED light emitter according to Patent Document 1 described above, the light emitter main body rotates in a state where it is attached to the socket because the base is rotatably assembled to the light emitter main body via the locking holder. Although it is possible, in the rotation operation of the light emitting unit main body, the elasticity of the elastic claw piece extending in an arcuate manner along the peripheral direction from the outer peripheral portion of the locking holder formed of synthetic resin as a material is used. Thus, a click feeling is generated, and when the claw of the elastic claw piece stops rotating at a predetermined position, the claw is stopped at the rotating position and serves as a stopper that restrains free rotation.

In the structure in which the free rotation of the base is restricted by the elastic force of the elastic claw piece described above, the variation in the dimensional accuracy of the elastic claw piece attached to the above-mentioned base or the locking holder is a restriction that restricts the free rotation of the base. The power will be affected. If the socket part of the fluorescent lamp fixture is a sandwiching and rotating socket, when mounting the lighting device, first insert the terminals of the caps at both ends of the lighting device into the central recesses in the socket unit, then Rotate the light emitting unit body 90 degrees and attach the terminal so that it is sandwiched between the metal terminal plates in the socket part, but if the restraining force that restrains the free rotation of the base is small, rotate the light emitting unit body 90 degrees When the operation is performed, the base rotates with respect to the light emitting unit main body, and there is a possibility that the lamp mounting operation may be finished without being attached to the socket, and there is a problem that the lamp falls. In order to prevent such a problem, JIS C7617-1 stipulates that the base does not rotate with a torque of 1 Nm or less with respect to the light emitting unit main body.
Moreover, the lighting fixture of patent document 1 mentioned above requires the operation | work which matches a screw and a screw hole, when fixing a spacer and a mounting seat part by screwing.

It will be attached after connecting.

When the straight tube type LED lamp 1 equipped with the rotating base 4 of the present invention is installed in the socket part of the fluorescent lamp fixture, the illumination direction is supported from the irradiation directivity of the LED luminous body arranged and attached on the surface of the support base 3. If it is specified in the surface direction of the base material 3 and is a direct-attached bottom open type lamp, the illumination direction will be on the floor surface side if it is mounted on this socket.
However, for example, when used for illumination of a display product or a signboard in a vending machine, it may not be possible to obtain appropriate illumination light immediately. In the straight tube type LED lamp 1 according to the present invention, the second cap members 9 at both ends are assembled to the light emitting unit main body 2 via the first cap member 8 so as to be rotatable. By rotating and fixing the base member 9 to a desired rotation angle, even when used for illumination with the above-described vending machine or signboard, appropriate illumination light irradiation can be obtained immediately.

The operation of the thus configured rotating cap 4 of the present invention will be described with reference to FIGS. FIG. 10 shows a state in which the second base member 9 cannot rotate.
The second base member 9 is normally biased toward the first base member 8 by the coil spring 12, and in this state, the outer peripheral wall 28 of the base rotation positioning holder 11 constituting the first base member 8. A rib-like convex portion 45 provided on the inner peripheral wall portion 44 of the second base member 9 is engaged in a gap between the extending portion 30 and the extending portion 29 for the rotation angle restraining means provided in the rotating shaft direction. In combination, the rotation of the second base member 9 is prevented. When the rotation of the second cap member 9 is performed in a state where the rotation of the second cap member 9 is prevented, as described above, both side surfaces of the extending portion 29 in the circumferential direction are centered on the rotation axis. On the other hand, since the surfaces are as parallel as possible, a moment of force acts in the circumferential direction orthogonal to the rotation axis, and the force is not inadvertently rotated.

Next, a state in which the second cap member 9 is rotatable is shown in FIG.
When the second base member 9 is rotated, the rotation angle restraining means of the base rotation positioning holder 11 is moved by moving the second base member 9 in the direction in which the length of the straight tube LED lamp 1 extends. Therefore, the engaged state of the rib-like convex portion 45 engaged with the gap between the extending portion 30 and the extending portion 29 can be released. In this state, the second base member 9 can be turned to the other extension portion 29 side. When the base member (B) 9 is turned to an arbitrary angle and released, the biasing force of the coil spring 12 causes The second base member 9 is biased toward the first base member 8, and a rib-like convex portion 45 of the second base member 9 is formed in the gap between the extension portion 29 and the extension portion 29 of the base rotation positioning holder 11. Engagement prevents the second cap member 9 from rotating.

  When the initial second base member 9 is rotated about 90 degrees from the position in the rotation direction, the rotation is blocked by the extension 30 for the rotation angle restraining means. The distance that can move the second base member 9 in the direction in which the length of the straight tube LED lamp 1 extends is such that the stepped surface 49 that is in the through hole 40 of the second base 9 and has a small diameter is the first base member 8. It is regulated by coming into contact with the flange surface of the stopper screw 43 screwed into the insertion hole 42 of the step pin 13. The movement distance that allows the second base member 9 to move linearly in the axial length direction is such that the engagement between the rib-like convex portion 45 of the second base member 9 and the extension portion 29 is released, but the extension for the rotation angle restraining means is not performed. It is set so as not to release the fitting beyond the height of the protruding portion 30.

  The rib-like convex part of the second base member 9 between the extension part 29 and the extension part 29 of the base rotation positioning holder 11 or between the extension part 29 and the extension part 30 for the rotation angle restraining means. In order to smoothly engage 45, a flat surface is not formed at the tip of the extension 29 and the tip of the rib-like convex portion 45, and an inclined surface is formed on either side from the center of the circumferential width. doing.

  In this embodiment, the rotation range of the second cap member 9 is set to about 90 degrees, and the rotation range is further divided into four equal parts so that the rotation can be performed about 22.5 degrees. A reference mark 46 is given to the first base member 8 attached and fixed to the light emitting unit main body 2 so that the current relative angle between the light emitting unit main body 2 and the second base member 9 can be understood, and the second second rotatable member. Marks 47 are provided in the circumferential direction of the base member 9 in increments of 22.5 degrees. This mark is integrally formed at the time of molding each member, but may be provided by post-processing by printing or the like. In this embodiment, the rotation range of the second base member 9 is set to about 90 degrees. However, it may be set to be less than that, and the increment of the rotation angle is not limited to about 22.5 degrees. You can set it to.

  As described above, the illumination direction is specified as the surface direction of the support base material 3 from the irradiation directivity of the LED light emitters arranged and attached on the surface of the support base material 3. On the other hand, since the second base member 9 can be rotated about 90 degrees, it can be varied up to 90 degrees parallel to the ceiling surface, with 0 degree when the surface direction of the support base 3 is a direction directly below the ceiling surface. . When the right and left longitudinal direction of the straight tube LED lamp with a rotating cap is changed when the straight tube LED lamp with a rotating cap of the present embodiment is mounted on the socket part of a fluorescent lamp fixture, the direction directly below the ceiling surface is 0 degree. The direction of 90 degree irradiation can be changed to the opposite side to the above. If the angle variable range is provided, a desired portion can be irradiated even in a straight tube LED lamp having directivity in the irradiation direction.

  The straight tube LED lamp 1 with the rotating base of the present invention formed as described above is provided with the second base members 9 at both ends of the straight tube LED lamp 1 with the base in advance so that a desired portion can be irradiated. The straight tube type LED lamp 1 is fixed by moving the length of the straight LED lamp 1 in the extending direction, rotating to a desired rotation angle, and releasing the hand from the second base member 9. The above rotation angle setting operation is performed one side at a time, the second cap members 9 at both ends are fixed at the same rotation angle, and the metal terminal pin 23 is attached to the socket portion of the fluorescent lamp fixture for use.

  In the said embodiment, although the nozzle | cap | die of the straight tube | pipe type LED lamp demonstrated by G13 type prescribed | regulated by JIS specification, this invention is not limited to this. For example, a base of “R17d”, “RX17d”, and “GX16t-5” may be used.
