Description

  The present invention relates to a straight tube fluorescent lamp type LED using an LED as a light source, and more particularly to an LED lamp capable of adjusting a light irradiation direction.

  Due to energy saving in recent years, fluorescent lamps using LEDs as light sources are commercially available, and power consumption is further reduced.

  This fluorescent lamp type LED lighting lamp has limited light irradiation direction, so there is no particular inconvenience when illuminating the floor direction from the ceiling for indoor lighting, but for example, a sample in a vending machine When used as illumination for illuminating a product, there are the following problems.

  That is, when the fluorescent lamp set in the lighting fixture in the vending machine is replaced with the LED lighting, depending on the position of the electrode receiving port of the lighting fixture on the same arrangement surface, irradiation is performed from the replaced LED lighting. In some cases, the light could not accurately illuminate the sample product in the vending machine.

  The object of the present invention is to adjust the irradiation direction of the light emitted from the LED lighting lamp even after the LED lighting lamp is set in the lighting device in the vending machine, An object of the present invention is to provide an LED lighting that can accurately illuminate a sample product.

  In order to solve the above-mentioned problems, the gist of the LED lighting lamp according to the present invention is a straight tube fluorescent lamp type LED lighting lamp using an LED as a light source, and the bases at both ends of the main body receive power. It is composed of at least two of a first base with pins for use and a second base connected to a light source unit with LEDs, and the first and second bases are rotatable around the axis of the main body. A stop position maintaining means is provided for maintaining the stop position when connected and when the rotation is stopped.

  In the form of this LED illumination lamp, a second base and a first base are connected to both ends of a straight tubular main body that houses a light source unit in which a large number of LEDs are arranged, from the main body side toward the main body axis.

The second base and the first base are connected so that the respective bases can rotate in the direction around the axis of the main body.
Although the method of connecting in a rotatable manner is not particularly limited, specifically, the other base is loosely fitted to one of the first base and the second base, or the one base is provided. The rotating shaft may be supported by a bearing provided on the other base so that each base can rotate in the direction around the axis of the main body.

The second base and the first base are provided with stop position maintaining means for maintaining the stop position when the rotation is stopped.
The stop position maintaining means for maintaining the stop position is not particularly limited. Specifically, one of the first base and the second base is provided with a claw that is repelled by the nature of the material or an external member. On the other hand, an engaging portion (protruding portion) in which a groove or a protrusion having a predetermined pitch with which the claw is engaged is provided so that the stop position can be maintained by the engagement between the claw and the engaging portion. Good.

  Further, when the power receiving pin of the first base is mounted on the socket of the lighting fixture, the range of the angle of rotation of the second base is adjusted to approximately 90 degrees, and the first base and the second base are rotated. It is desirable to restrict the twisting of the power cable connected to the light source unit in which the power receiving pin of the first base and the LED of the second base are arranged.

  In the case where the twisting of the power cable is restricted, a plurality of the stop position maintaining means described above may be arranged in the rotation direction so that the stop position is firmly held.

  The claw and the engaging portion are formed by separate members from the first base and the second base, and are attached to predetermined portions of the first base and the second base, or the first base and the second base. It may be formed integrally when molding.

  In the light source unit, for example, a large number of LEDs are arranged on a printed circuit board, and the light emission power of the LEDs is received by a cable connected to a power reception pin of the first base.

  In addition, the connection between the light source unit and the second base is achieved by connecting the light source unit and the second base by fitting the other convex portion into one concave portion, or by a fixing means such as a screw or an adhesive. And the second base may be connected.

  The straight tubular main body that houses the light source unit includes a cylindrical or arched cover made of a transparent or milky white predetermined material.

  According to the LED illumination lamp of the present invention, since the irradiation direction of the light emitted from the LED illumination lamp can be adjusted even after the LED illumination lamp is set in the lighting fixture in the vending machine, the sample product in the vending machine can be adjusted. Can be accurately illuminated, and the existing fluorescent lamp set in the luminaire can be immediately replaced with the LED illuminating lamp, so that the power consumption can be saved quickly.

  And, by using this LED illumination lamp for a lighting fixture that uses the fluorescent lamp in the showcase as a light source, it is possible to accurately illuminate the products in the showcase, and the illumination lamp at the place where indirect illumination is performed If it uses for, the light irradiated from a LED illumination light can be irradiated to a reflected part exactly.
