  The present invention relates to an LED lamp for electric decoration used as a light emitter of an electric decoration device, and relates to an LED lamp for electric decoration capable of changing the irradiation angle of the LED lamp.

  An LED luminous body unit using an LED lamp as a light source is described in Patent Document 1. This Patent Document 1 is composed of an LED light-emitting unit in which an LED lamp is housed in a housing part, and an acrylic cover in which a hollow part is provided in a cover light-emitting part located in front of the LED light-emitting part, and the cover light-emitting part is more than the LED light-emitting part. , And the light emitted from the LED lamp is diffusely reflected and diffused in the hollow part of the cover light emitting part, so that the lighting area is larger than the light source.

On the other hand, Patent Document 2 describes an LED lamp reflector that can effectively use light emitted from directions other than the front of the LED lamp. According to this LED lamp reflector, it is a lens for reflecting the side light of the LED lamp forward, and has a reflector body whose reflecting surface is a rectangular surface or an approximate curved surface thereof. A concave portion for housing the LED lamp is formed in the central portion of the reflecting surface of the reflector body, and the traveling direction of light emitted forward from the LED lamp is corrected at the front position of the LED lamp in the concave portion. The lens for providing is provided.

  As described in Patent Literature 1, the area of the cover light emitting portion is made larger than that of the LED light emitting portion, and the light emitted from the LED lamp is diffusely reflected and diffused in the hollow portion of the cover light emitting portion. As described above, a concave portion for housing the LED lamp is formed in the central portion of the reflecting surface of the reflector body, and the traveling direction of light emitted forward from the LED lamp is corrected at the front position of the LED lamp in the concave portion. It was impossible to change the irradiation direction of the light source with the lens provided with the lens.

  That is, in the conventional LED lamp, a technique for effectively using the light amount in the irradiation direction of the LED lamp has been proposed, but a technique for changing the irradiation direction of the LED lamp itself has not been proposed. Therefore, the present invention aims to provide an unprecedented LED lamp for electric decoration by efficiently emitting light while using a small LED lamp and changing the angle of the irradiation direction.

  In order to solve the above-described problems, a first means of the present invention is an LED lamp for electric decoration in which the LED lamp 1 is housed in a plastic socket body 2 to form the LED socket 10. The transparent waterproof cover 5 is covered and fixed, and a prism 5A is erected on the upper surface of the waterproof cover 5 so that the irradiation direction of the LED lamp 1 is changed by the prism 5A.

  The second means is that the LED socket 10 is formed with a housing recess 3 for housing the LED lamp 1 in the form of a rectangular chip at the upper end of the socket body 2, and a pair of contact terminals 4 are arranged inside the socket body 2. One of the contact terminals 4 is in contact with the terminal 1A of the LED lamp 1 housed in the housing recess 3, and the other is in contact with the chip resistor 6 disposed in the socket body 2, and the LED in the housing recess 3 is provided. The terminal 1A of the LED lamp 1 is provided so as to contact the contact terminal 4 and the chip resistor 6 when the lamp 1 is fitted.

  In the third means, the prism 5A is provided with a transparent acrylic resin.

  The fourth means is that the outer periphery of the lower end portion 11 of the LED socket 10 bulges from the outer periphery of the upper end portion 12, the outer periphery of the lower end portion 11 is covered with an adhesive fixing body 13 made of vinyl chloride, and the adhesive fixing body 13 is covered. It is bonded to a vinyl chloride cord tape 30.

  The fifth means is that a fitting fixing body 14 made of ABS resin is attached and fixed to the lower end portion 11 of the LED socket 10, and a substantially conical locking protrusion 15 is projected from the lower surface of the fitting fixing body 14. The means for solving the problem is that the locking projection 15 is fitted and locked in the fixing hole 40 opened at the mounting position of the LED socket 10.

  According to the first aspect of the present invention, since the prism 5A is provided in the irradiation direction of the LED lamp 1, the irradiation angle of the LED lamp 1 can be changed by the prism 5A. As a result, it is possible to perform electrical decoration having an unprecedented irradiation effect.

  According to the second aspect of the present invention, the rectangular chip-shaped LED lamp 1 for the printed board is arranged on the upper end portion of the socket body 2 to form the LED socket 10, and the LED socket 10 is individually attached to the power cord. The configuration of the LED lamp for electrical decoration of the present invention becomes compact and the height can be lowered. As a result, even if the small LED lamp 1 is used, it is possible to efficiently irradiate light and change the irradiation direction. Moreover, even if the prism 5A is provided on the waterproof cover 5, the mounting position is low and it is possible to install in a narrow place. For example, when attaching direct lighting, indirect lighting, side lighting, etc. Appropriate lighting can be applied.

  According to claim 3, by providing the prism 5A with a transparent acrylic resin, it is possible to provide the prism 5A at a low cost and to obtain a sufficient light refraction effect.

  According to the fourth aspect, the outer periphery of the lower end portion 11 of the LED socket 10 bulges from the outer periphery of the upper end portion 12, the outer periphery of the lower end portion 11 is covered with the adhesive fixing body 13 made of vinyl chloride, and the adhesive fixing body 13 is chlorinated. By adhering to the vinyl cord tape 30, the socket body 2 and the cord tape 30 can be securely fixed even if a polycarbonate material having a poor compatibility with the vinyl chloride cord tape 30 is used for the socket body 2. .

  According to the fifth aspect of the present invention, the fixing projection opened in the mounting position of the LED socket 10 is provided so as to fit and lock the locking projection 15, thereby fixing the mounting position in the mounting position. Since the LED socket 10 can be fixed simply by inserting the locking protrusion 15 into the hole 40, the LED lamp for electrical decoration of the present invention can be mounted very easily.

  In this way, according to the present invention, while using a small LED lamp, it is possible to provide an LED lamp for electric decoration that has never been achieved by efficiently emitting light and changing the angle of the irradiation direction. There are various beneficial effects.

  In the best mode of the LED lamp of the present invention, a transparent waterproof cover 5 is covered and fixed on the upper surface of the LED lamp 1.
