Hereinafter, the configuration and operation of an embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the following examples are provided to enable those skilled in the art to fully understand the present invention, but the scope of the present invention is not limited by the embodiments described below.

1 is a schematic diagram of a first embodiment of an LED assembly with improved visibility and formability according to the present invention. As shown in FIG. 1, the LED assembly having improved visibility and formability according to the present invention includes an LED 1, a light transmitting unit 10, and a fixing unit 30.

LED used in the present invention is not particularly limited in its form. For example, not only the case where the LED light emitting part is long as shown in FIG. 1 but also the case where the LED light emitting part is short as shown in FIG. Here, when the LED emitting portion is short as shown in FIG. 2, the brightness of the side surface of the LED may be further emphasized as compared with FIG. 1. Furthermore, when the LED light emitting portion is short as shown in FIG. 2, the shape of the light transmitting portion may be modified according to the shape of the LED light emission. 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 designates the irradiation range as the size of the shape to increase the concentration of light, and various expressions can be made according to the shape of the shape. To be expressed. In addition, since the light-transmitting portion 10 surrounds the light emitting portion 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 light transmitting part 10 in the present invention is characterized by consisting of at least one thin film light emitting portion 12 and at least one thick film light transmitting portion (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 transmitting part 12, the glare phenomenon immediately in 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 be strongly radiated 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 it exceeds 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. 3 illustrates a light transmitting part having a hemispherical shape as an example of various three-dimensional shapes. Here, the upper portion of the transmissive portion 10 may be formed flat on the upper portion of the transmissive portion 10 as shown in FIG. 1 or 2 in order to improve the adhesion when contacting the glass or plastic.

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. 4 is a view showing that the thin film light-emitting part 12 is engraved. As shown in Fig. 4 (a) to (d), the thin film light-transmitting portion 12 is a portion engraved in the light-transmitting portion, the other portion is the thick film light-transmitting portion (14).

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. 5 is a view showing that the thick-film light-transmitting portion 14 is embossed. As shown in Fig. 5 (a) to (d), the thick film light transmitting portion 14 is an embossed portion in the light transmitting portion, the other portion is a thin film light transmitting portion 12. In the case of FIG. 4, the thick-film light-emitting part 14 is positioned at the center and the thin-film light-emitting part 12 is positioned around it.

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. FIG. 6 is an exemplary view illustrating an LED assembly in which a plurality of thin film light emitting parts 12 and a thick film light transmitting part 14 are present. As shown in Figs. 6 (a) and 6 (b), there is an embossed thick film projection portion 14 'positioned at the center and another thick membrane projection portion 14 " positioned at the edge, and there is a negative angle therebetween. The thin film light-emitting part 12 which existed exists. Therefore, in the case of FIG. 6 (a), the thin film light-emitting part 12 between the center circle 14 'and the edge circle 14' 'of the edge is seen to be the brightest. In this case, the thin film light emitting part 12, which is a space between the central star 14 'and the square 14 " 4 to 6 only show the flat portion of the upper portion of the light transmitting portion.

Also, 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. Among them, silicone having excellent moldability and polycarbonate having excellent light expandability are most preferred.

The fixing part 30 is a part located at the bottom of the LED 1 and the light transmitting part 10, and is a part contacting the fixture when the LED assembly according to the present invention is attached to another object. If necessary, the PCB substrate is located in this part or includes a PCB substrate therein and serves as a support for protecting the LED assembly according to the present invention.
