1 is a cross-sectional view of an LED assembly used in the present invention. As shown in FIG. 1, the LED assembly 100 according to the present invention includes an LED 1, a light transmitting unit 10, and a fixing unit 30. Each part is demonstrated below.

LED used in the present invention is not particularly limited in its form. For example, the case where the LED light emitting portion is long as shown in FIG. 1, but also the case where the LED light emitting portion is short. In this case, when the LED light emitting portion is short, the brightness of the side surface of the LED may be further emphasized compared to FIG. 1. Furthermore, when the LED light emitting portion is short, the shape of the light transmitting portion may be modified according to the shape of the LED light emitting portion. In addition, although the light emitting portion is short, it is natural that a wide LED and a round LED may also be applied to the present invention.

At least one LED is used in the present invention. There is no particular limitation on the number of LEDs here. When a plurality of LEDs are installed, LEDs of different colors may be installed, or may be installed with different angles at which individual LEDs are installed. This is to improve visibility at various angles in consideration of the linearity of light emitted from the LED.

The light transmitting part 10 surrounds the light emitting part of the LED 1, transmits the light of the LED 1 to the outside, and has a flat bottom surface. The light emitting unit 10 prevents light from being scattered and increases the concentration of light by designating the irradiation range as the size of the shape, and various expressions can be made according to the shape of the shape. To be expressed. In addition, since the light-transmitting part 10 surrounds the light emitting part of the LED 1, it serves to protect the LED 1 from the external impact applied to the LED (1). The light emitted from the LED 1 is emitted to the outside through the light-transmitting portion 10, the light is reflected, diffraction, etc. while passing through the light-transmitting portion 10. The shape of the light transmitting part 10 in the present invention is not particularly limited, but in order to further improve visibility, it is preferable to include at least one thin film light transmitting part 12 and at least one thick film light transmitting part 14.

The thin-film light-emitting part 12 is a thin portion of the light-transmitting part in order to reach the light of the LED 1 to a long distance, in order to alleviate the glare phenomenon at a short distance, especially in front of the LED, the thick-film light-emitting part 14 is the LED (1) The thickness of the light transmitting part is thicker than the thin film light emitting part 12 in order to emphasize the shape by easily dispersing the light of the LED and also easily recognize the light of the LED 1 from the side of the LED 1. Since the thickness of the medium through which the LED 1 light passes is thin in the thin film transmitting part 12, the light passes almost without any loss of energy, so that even people at a relatively long distance are emitted from the thin film transmitting part 12. It becomes possible to recognize the light. However, since the thin film is also present in the thin film light-emitting portion 12, the glare phenomenon at the front of the LED is alleviated.

The thickness of the thin film light-transmitting portion 12 depends on the brightness of the LED to be installed. In the case of a conventional LED, the thickness is preferably 0.1 to 10 mm. If it is less than 0.1mm, there is glare in front of it, and if it exceeds 10mm, the LED light is disturbed by the thin-film light emitting part and it is difficult to reach far.

The thin-film light-emitting part 12 allows the light to reach a long distance, while also reducing the glare in front of the LED to improve the overall visibility.

The thin film light emitting part 12 may be formed by drilling a hole in the light transmitting part 10 to make the thin film light transmitting part thinner than the surroundings, or by forming a portion of the outer surface of the light transmitting part to which light is strongly emitted to be thinner than the surroundings. .

In FIG. 1, the thin film light-transmitting part 12 is shown in a flat shape when viewed from the side, but if necessary, it may have a convex shape in which light may be diffused or a concave shape in which light may be collected.

The thick-film transparent portion 14 is a portion where the thickness of the transparent portion is thicker than the thin-film transparent portion 12, and since the medium is thick, a part of the light passing through the medium is reflected inside, so that the light is spread over the entire thick-film transparent portion 14. This is dispersed and released to the outside. Therefore, the light emitted from the thick film transmitting part 14 is darker than the light emitted from the thin film transmitting part 12, but it is dispersed as a whole so that the shape can be recognized from the front as well as the side of the emitting direction of the LED 1. do.

As a result, the light emitted from the thin-film light emitting part 12 reaches far in front of the LED 1 so that people at a distance can easily recognize it, while alleviating the glare just in front of the LED, so that it is near, especially in front of it. Even without eye fatigue, the LED 1 light can be recognized, and the light emitted from the thick film transmitting part 14 emits the LED light from the side of the LED 1, so that the direction of the light of the LED 1 is progressed. In terms of, the form can be easily recognized by people, contributing to the improvement of form. Furthermore, the light from the thin film light emitting part 12 is bright, and the light from the thick film light transmitting part 14 is softly reflected, and the thin film light transmitting part 12 and the thick film light transmitting part 14 are harmonized to produce a visually excellent effect. have.

The thickness of the thick film transmitting part 14 is not particularly limited, but it is preferable that the thick film transmitting part has a thickness of 1.5 to 20 times that of the thin film transmitting part 12 in order to emit light to the side surface. If less than 1.5 times, there is no difference in the brightness of the thin film and the thick film transmitting portion, if more than 20 times, there is a problem that the amount of light emitted to the outside is too small.

There is no particular limitation on the positions of the thin film light emitting part 12 and the back light transmitting part 14, but when considering the straightness of the light emitted from the LED 1 to reach the distance from the thin film light emitting part 12 to a long distance. Preferably, the LED 1 is formed on the front surface in which the light is most strongly emitted, and the thick film light-emitting portion 14 is preferably installed around the thin film light-emitting portion 12.

The number of the thin film light emitting part 12 and the thick film light transmitting part 14 is not particularly limited, and may be formed as many as necessary.

There is no particular limitation on the overall shape of the light transmitting part 10. Although shown in FIG. 1 with reference to a tetrahedron, if necessary, it may have various three-dimensional shapes, such as a trihedron, a pentagon, a hexahedron, and a hemispherical shape.

In addition, there is no restriction | limiting in particular about the form at the time of seeing the thin film light transmission part 12 and the thick film light transmission part 14 from the top. In general, it is circular, but in some cases, it may have a specific shape or character, including stars, triangles, squares, animal patterns, human figures, letters, and the like. In this case, it is possible to recognize the shape of a figure or a character formed in the thin film light emitting part 12 or the thick film light transmitting part 14 from the outside.

Since the thin film light emitting part 12 means a portion where the thickness of the light transmitting part is relatively thin, the thin film light transmitting part 12 first forms the light transmitting part and then inclines the portion corresponding to the thin film light emitting part 12 in the light transmitting part. It can be implemented by. In addition, since the thick-film light-emitting part 14 means a portion where the thickness of the light-transmitting part is relatively thick, the thick-film light-emitting part 14 forms a light-transmitting part and by embossing a portion corresponding to the thick-film light-emitting part 14 in the light-transmitting part. Can be implemented. Furthermore, by appropriately combining the relief and the intaglio, it is also possible to have a plurality of the thin film light-emitting portion 12 and the thick film light-transmitting portion 14 present.

In addition, in order to emphasize the visual effect of the LED light emitting device, the thin film light emitting part 12 or the thick film light transmitting part 14 may be colored. Here, the thin film transmitting part 12 and the thick film transmitting part 14 may be painted in the same color, or may be painted in different colors. In addition, a plurality of colors may be painted on the thin film light emitting part 12 and the thick film light transmitting part 14 simultaneously. Furthermore, the color may be painted only on the outside of the thin film transparent part 12 and the thick film transparent part 14. In addition, the colors emitted from one LED may be variously expressed by making the colors of the LED and the light emitting part the same or different from each other.

The material of the light-transmitting portion 10 is not particularly limited, but may be formed of a material which can be molded and can transmit light. As an example, glass, plastic, silicone, latex, rubber, urethane, resin, epoxy resin, polycarbonate, or polymer may be mentioned. Of these, silicone having excellent moldability and strong impact resistance is most preferred.

Furthermore, the thin film light transmitting part 12 or the thick film light transmitting part 14 may be expressed in various ways by using any one or more of transparent, semitransparent, or opaque materials.

The fixing part 30 is a part located at the bottom of the LED 1 and the light transmitting part 10, and attaches the LED assembly 100 to the main body 200 and fixes the LED. Here, the main body 200 means a portion to which the LED assembly is attached in a product including a band to be described later. However, for the sake of convenience, 200 is used as the quotation mark in the band. If necessary, the PCB substrate is located or includes the PCB substrate therein. Although the fixing part 30 is illustrated as having the same diameter as the light transmitting part 10 in the drawing, the diameter of the fixing part may be different from the light transmitting part as necessary.

The base may be additionally installed outside the fixing portion. The base may be formed in various forms, but basically has a structure that can be in close contact with the light-transmitting part, but also to accommodate the LED inside to protect the LED from external shocks. 2 is a cross-sectional view of an LED assembly with a base, and FIG. 3 is a plan view of the LED assembly with the light transmitting portion removed. The base 70 includes a base 71, a side wall 73 and a wire connecting groove 76. The support portion 71 is formed with a rim 72 larger than the diameter of the fixing portion 30. The diameter of the rim can be adjusted as needed. The side wall 73 is a portion protruding upward from the base 71, and the light transmitting portion is coupled to the side wall. Therefore, coupling means such as screw grooves or coupling jaws may be formed on the sidewalls for coupling with the light transmitting portion. The side wall 73 generally has a cylindrical shape, and an inner space in which the LED is accommodated is formed in the side wall 73.

The wire connecting groove 76 is a groove passing through the support part 71, and an electric wire (not shown) is connected to this part. The wire connecting groove 76 should be formed at a position where the wire can pass to the anode and the cathode of the LED 1 formed in the fixing portion 30. The connecting screw 35 is coupled to the positive electrode and the negative electrode of the fixing part 30 in the vertical direction, respectively, and the connecting screw 35 penetrates the fixing part 30 in the vertical direction. The wire inserted into the wire connecting groove 76 is inserted in a state where the coating is not peeled off, and the connection screw 35 rotates to penetrate through the coating of the electric wire inserted into the wire connecting groove 76 so that the positive and negative poles of the LED are fixed. Are each electrically connected to a wire.

In the related art, it is cumbersome to remove the covering of the wire for connection with the LED, and in the case of changing the position of the LED once installed, the wire is additionally connected or the wire is left to be stretched. If the connection is simple, when changing the LED position, simply loosen the connection screw, change the position of the LED, and then tighten the connection screw again.

4 is a cross-sectional view of the base as another embodiment. In this case, there is an open lower opening 78 at the lower part of the base 70, and the lower opening 78 is a form in which the LED can be inserted. In the case of the base 70 in which the lower opening 78 is formed, the wire connection groove is not installed. In the method of coupling this to the main body 200, the base 70 is coupled to the fitting hole 202 of the main body 200, and then the LED is inserted through the lower opening 78 to be coupled.

Regarding the method of attaching the LED assembly 100 to the main body 200, the entire LED assembly 100 is made integral and attached to the main body 200, or the light transmitting part 10 and the LED 1 are separated from each other. It may be made to be fitted to the main body 200. When the whole is made in one piece, the LED assembly 100 may be attached to the main body 200 in various ways. There is no particular limitation on the attachment method here, but considering the convenience of the work process, the high frequency attachment method is most preferred. Furthermore, a fixing pin 40, such as a wire that can be bent at the lower part, is attached to the fixing part, and the fixing pin 40 is penetrated through a part to be attached to the body, and then the fixing pin 40 is bent to the main body. It can also be attached. 5 is a cross-sectional view of the LED assembly to which the fixing pin is attached.

As another attachment method, a plurality of fitting holes 202 are made to the main body 200 at regular intervals, and the LED assembly 100 is inserted into the fitting holes 202. Typically, such a coupling method is called a back fitting method. In this case, if the diameter of the fitting hole is equal to or smaller than the diameter of the light transmitting part and the light fitting part is inserted into the fitting hole, the light transmitting part can be completely caught in the fitting hole.

Furthermore, in order to further strengthen the strength of the coupling, a concave portion of a concave shape may be further formed in the lower portion of the light transmitting portion. The recessed portion has a function of coupling the light transmitting portion and the main body, and refers to a concave shape, a shape of an insertable groove or a shape having a supportable groove. 6 is a cross-sectional view of the LED assembly in which the recess is formed. In the LED assembly 100, the recess 90 is disposed below the light transmitting part 10, and the main body 200 is coupled to the side of the light emitting part 10. This is the light-transmitting portion 10 is made of a soft material is fitted to the fitting hole 202. The recess 90 may be located at the lowermost portion of the light transmitting portion 10 as shown in FIG. 6, but may be formed in the middle of the light transmitting portion. The recess is inserted and fixed in the main body.

On the other hand, when the light transmitting portion 10 and the LED (1) is separated, as shown in Figure 7, the insertion hole 202 in the main body, the light emitting portion 10 is placed on the upper portion of the fitting hole 202, the fitting In the lower part of the ball 202, the LED (1) portion is pushed in the form of fitting from the bottom to the upper part to combine with the light-transmitting part (10). This is commonly called a front fitting method, and the body is fixed between the light transmitting part and the fixing part. In this case, the LED 1 and the light projecting portion 10 are brought into close contact and fixed. Of course, on the contrary, the LED 1 may be first inserted into the lower portion of the fitting hole 202, and the light transmitting portion 10 may be coupled to the upper portion thereof. In addition, if there is a base, the base is fitted into the fitting hole and is coupled to the light transmitting part 10.

In this case, in order to increase the strength of the coupling, a support 50 for a support method using a groove or a screw for supporting the LED 1 may be additionally installed. The support 50 is in close contact with the light transmitting part 10 to completely fix the LED 1 in the light transmitting part 10, and is a part for preventing damage due to shaking of the LED 1. 8 is a cross-sectional view of the LED assembly in which the support is further installed. As shown in Figure 8, the support 50 is in close contact with the side of the light transmitting portion 10.

The power supply is a part for supplying power for emitting LED, and there is no particular limitation on this. For example, at least one of a capacitor, a battery, a direct current power source, a solar cell, or a hybrid. Preferably a battery is used in consideration of the convenience of movement and possession.

On the other hand, the LED assembly attached to the main body in the present invention may further attach a light diffusion cap in order to improve visibility at long distances and near. The light diffusion cap can take the shape of convex or concave or flat shape and has the effect of maximizing the diffusion and dispersion of LED light. 9 is a schematic diagram of an LED assembly in which a light diffusion cap is further formed. Light diffusion cap 80 is a form surrounding the LED (1), the lower portion of the light diffusion cap 80 is coupled to the fixing portion 30, from the lower portion of the fixing portion 30 to the side of the LED (1) It forms a thin wall and rises to the top, and the light diffusing lens of the convex, concave or flat form is formed in the upper part of LED1. In addition, the light diffusion cap 80 may be attached to the vertical wall, in which case the convex, concave or flat light diffusion lens is attached to the vertical wall. The light emitted from the LED 1 is more widely distributed in the primary in the light diffusion cap 80, and is further more widely distributed in the secondary by the thin film light emitting part and the thick film light transmitting part located outside the light diffusing cap 80 again.

The LED assembly according to the present invention can further attach a polycarbonate layer on top of the light transmitting portion to improve visibility. Polycarbonate emits light with a very stable feeling because of its high light diffusion and high visible light transmittance. The light diffused primarily through the light-transmitting part is diffused into the light while passing through the polycarbonate to a light having a stable feeling, thereby improving overall visibility. 10 is a cross-sectional view of an LED assembly with a polycarbonate layer attached. As shown in FIG. 10, the polycarbonate layer 84 is attached to the light transmitting part 10. There is no particular limitation on the shape of the polycarbonate layer 84 attached thereto, but in order to diffuse light, the upper portion preferably has a convex lens shape. The polycarbonate layer 84 is not particularly limited to the method of attaching to the light transmitting portion, but may be simply installed by inserting the polycarbonate layer 84 into the groove formed by engraving the upper portion of the light transmitting portion.

In order to diffuse the LED light emitted from the LED assembly in the present invention, a diffusion layer may be further attached to the lower portion of the light emitting portion facing the upper portion of the LED. 11 is a cross-sectional view of the LED assembly with a diffusion layer attached. The diffusion layer 86 is made of a material capable of diffusing light as much as possible. Particularly, the diffusion layer 86 is preferably made of a material capable of diffusing light including a crystal in order to cause diffuse reflection. The light primarily diffused by the diffuse reflection by the diffusion layer 86 is further diffused while passing through the light-transmitting portion 10, thereby widening the range of the light emitted by one LED assembly as a whole.
