Description

  The present invention relates to a tubular electric decoration using a light-emitting diode, and obtains a method for manufacturing a high-quality tubular electric decoration and a light emission direction control method for the tubular electric decoration that can be applied to various light source products. For the purpose.

  FIG. 13 to FIG. 15 are conventional tubular electric decorations. In FIG. 13, a light emitting diode (hereinafter referred to as LED) is attached in close contact with a side surface of an optical medium 1a formed by molding a composite of transparent urethane and a fine reflecting material into a rod shape. It is a small-diameter cylindrical electric ornament with a limited distance that can utilize the light from the LED 2.

  In FIG. 14, a large number of LEDs 2 are attached in close contact with the side surface of the optical medium 1 b in which fine scratches are made on the front surface or the back surface of the cylinder. The light traveling straight in the optical medium 1b hits the scratches and diffusely reflects and shines. It is a cylindrical electric decoration which can make optical medium 1b large.

  In FIG. 15, an electrical unit 3 having a large number of LEDs 2 disposed therein is inserted into an internal cavity of a transparent or colored milk half and cylindrical optical medium 1 c. The shape of the electrical unit 3 includes a circle, a triangle, a square, or a two-sided shape. The light emission intensity of the optical medium 1c is high. Depending on the clearance between the electrical unit 3 and the inner wall of the optical medium 1c, spot light is generated on the optical medium 1c, or uneven light emission occurs. The cause of these occurrences is that it is difficult to assemble the two to keep the clearance constant.

  The task is to create a technical idea using the laws of nature that can accurately achieve the assembly of both the optical medium and the illumination unit that constitute the tubular illumination body.

Therefore, we have created a technology that can achieve the role of a positioning spacer by abutting with the mating member.In addition, the present invention achieves an accurate positional relationship by utilizing the entanglement of the mating member using the existing stress of the member. Created a technology that can be used.
It uses a light emitting diode continuous belt twisted in a screw shape or a spiral shape,

    A light emitting direction control method for a cylindrical electric decoration characterized in that a light emitting diode continuous belt twisted in a screw shape or a spiral shape is used.

The twisted plastic member has three-dimensional edges and surfaces of the member, and can contact the mating member to achieve the role of a positioning spacer.
The anti-plastic member to which the twist is applied not only can achieve the role of a positioning spacer by abutting against the mating member, but also increases the abutting strength with the mating member by utilizing the existing stress generated in the member from the twist. The antiplastic member is flexible and can be freely deformed and adapted to the inside of an optical medium such as a tube, and can be easily inserted into the tubular optical medium by utilizing this degree of free deformation. Further, it can flexibly follow the deformation of the tubular optical medium that often occurs during use.

  When the light-emitting diode connecting belt, which is twisted and developed three-dimensionally, comes into contact with the mating member and fulfills the role of a positioning spacer, the contact accurately determines the relative positional relationship between the two. When the positional relationship is accurately determined, the assembly from the light source to the light medium member with the designed clearance becomes possible. As a result, spot light, light unevenness, or light emission direction can be controlled. The control method can consider many means, such as offset of the arrangement line of the light emitting diode to a continuous belt, geometric arrangement, or random arrangement. Moreover, the protrusion height of a light emitting diode can consider the raising means (refer FIG. 16) which added the flange to the edge of the continuous belt.

When the high-quality cylindrical electric decoration using the present invention and the control of the light emission direction are used, the translucent handrail pipe installed on the wall surface of the staircase can be illuminated uniformly. It can be set as the outdoor signboard which combined many shining rod-like blocks. Even though the cross-sections are pipes of various shapes such as round, triangular or square, these pipes can be uniformly illuminated by a simple manufacturing method. A curb installed on the sidewalk of the park may be used as a method of light guidance, or it may be turned on in turn in the direction of travel in the LED array by the flexible circuit board wiring, blinking every other color, It is also possible to freely control the difference LED such as blinking. The pipe may be transparent or a milk semi-acrylic pipe. Further, the pipe surface may be semi-transparent plated with a pseudo metal.
The tubular electric decoration is not limited to an electric decoration tube, but can be used as an alternative to a fluorescent tube, and is provided for various light source products.

  The LED is mounted on the strip-shaped flexible substrate at equal intervals (in some cases, at geometric intervals or at random intervals) or elastically mounted, and this mounted flexible substrate is made of plastic metal such as strip-shaped aluminum, rubber or resin anti-plasticity A light emitting diode continuous belt is configured by being attached to a member. The light emitting diode continuous belt is twisted in a spiral or spiral shape, and the light extraction method is changed depending on the twist frequency.

  The light emission direction is controlled by intermittently adding to the array pattern of the light emitting diodes.
