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 view of an umbrella having a light emitting device according to the present invention. As shown in FIG. 1, the safety umbrella according to the present invention includes an LED assembly 100, a battery 600, and a switch 700.

The umbrella is typically composed of a handle 250, an umbrella stand 260 connected to the top of the handle, a plurality of umbrella poles 270 branched from the umbrella stand, and a tarpaulin 280 attached to the umbrella stand to prevent rain. . Safety umbrella 200 in the present invention may be made of iron umbrella stand and umbrella stand, but preferably manufactured using synthetic resin. Therefore, it can be used safely even during a thunderstorm, and there is no problem of rust caused by rainwater. The tarpaulin may be a conventional tarpaulin, but it is preferable to use a material that is not easily torn in consideration of the LED assembly 100 is attached to the tarpaulin.

As shown in Figure 1, the safety umbrella according to the invention a plurality of LED assembly 100 is attached at regular intervals. The part where the LED assembly is attached to the umbrella can be attached to the tarpaulin as well as the umbrella stand and the umbrella stand. This enables various expressions such as alphanumeric figures using the LED assembly.

2 is a cross-sectional view of the LED assembly used in the present invention. As shown in FIG. 2, 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 LED light emitting part is not only long as shown in FIG. 2 but also the case where the LED light emitting part is short as shown in FIG. 3. Here, when the LED emitting portion is short as shown in FIG. 3, the brightness of the LED side surface may be further emphasized as compared with FIG. 2. Furthermore, when the LED light emitting part is short as shown in FIG. 3, the shape of the light transmitting part may be modified according to the shape of the LED light emitting part. In addition, although the light emitting part is short, it is natural that the LED of the wide shape and the round shape can also be applied to the present invention. The LED used in the present invention preferably uses a high brightness LED in order to improve visibility.

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-transmitting 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 are possible according to the shape of the shape, and several colors and shapes in one LED assembly 100 are provided. And brightness can 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. Although there is no particular limitation on the shape of the light transmitting part 10 in the present invention, at least one thin film light emitting part 12 in order to further improve visibility at long distance / near distance and front / side while not obstructing the field of view of adjacent workers. ) 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 in the 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. Therefore, it does not interfere with the vision of others nearby.

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. 2, the thin film light-emitting 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 easily recognized from the front as well as the side of the emitting direction of the LED 1. Will be.

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. The light emitted from the thick-film floodlight 14 is emitted from the side of the LED 1, and the shape of the LED 1 is also emitted in terms of the direction of the light. This makes it easier for people to recognize and contributes to improved visibility. Furthermore, the light from the thin film light-emitting part 12 is bright, and the light from the thick film light-emitting part 14 is softly reflected, and the thin film light-emitting part 12 and the thick-film light-emitting part 14 are harmonized to produce a visually excellent effect. Visibility at far / near and front / side is improved.

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. 2 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. 4 illustrates a light transmitting unit having a hemispherical shape as an example of various three-dimensional shapes.

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. Of course, it is generally circular. 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. 5 is a view showing that the thin film light-transmitting portion 12 is engraved. As shown in Fig. 5 (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. 6 is a view showing that the thick-film light-transmitting portion 14 is embossed. As shown in Figs. 6 (a) to 6 (d), the thick film light transmitting portion 14 is an embossed portion of the light transmitting portion, and the other portion becomes the thin film light transmitting portion 12. In the case of FIG. 6, 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. 7 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. 7 (a) and 7 (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 an intaglio therebetween. The thin film light-emitting part 12 which existed exists. Therefore, when viewed from the outside, the thin film light-emitting portion 12 between the central circle 14 'and the circular circle 14' 'at the edge has the brightest effect. In this case, the thin film light emitting part 12, which is a space between the central star 14 'and the square 14 " 5 to 7 show only the flat portion of the upper portion of the light transmitting portion.

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 is a part for attaching the LED assembly 100 to an umbrella. If necessary, the PCB substrate is located or includes the PCB substrate therein. The diameter of the fixing part 30 can be adjusted large or small as needed.

The LED assembly attached to the safety umbrella in the present invention may include additional parts described below to improve visibility at long distances and near distances. This is to prevent accidents by improving visibility and to be easily rescued by others when an accident occurs.

As an example, the LED assembly 100 may further form a convex lens part to improve visibility at long distances and near distances. 8 is a schematic view of an LED assembly in which a convex lens portion is further formed. The convex lens part 80 surrounds the LED 1, and the lower part of the convex lens part 80 is coupled to the fixing part 30, and from the lower part of the fixing part 30 to the side of the LED 1. Forming a thin wall to the top, the convex lens is formed in the upper portion of the LED (1). The light emitted from the LED 1 is more widely distributed in the primary in the convex lens unit 80 and is further more widely distributed in the secondary by the light transmitting unit 10 located outside the convex lens unit 80. The convex lens may have both convex surfaces, unlike in FIG. 8.

The LED assembly according to the present invention may further attach a polycarbonate layer on top of the light transmitting part as another example 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. 9 is a cross-sectional view of an LED assembly with a polycarbonate layer attached. As shown in FIG. 9, a 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. 10 is a cross-sectional view of the LED assembly with the diffusion layer attached. The diffusion layer 86 is made of a material capable of diffusing light as much as possible, and in particular, the diffusion layer 86 is preferably made of crystal in order to cause diffuse reflection. The light diffused primarily 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 light emitted by one LED assembly as a whole. The diffusion layer 86 is not particularly limited to the method of attaching to the light transmitting portion 10, but may be simply installed by inserting the diffusion layer 86 into a groove formed in the light transmitting portion.

Regarding the attachment method of the LED assembly 100 to the safety umbrella 200, the entire LED assembly 100 is made integrally and attached to an umbrella, or the floodlight 10 and the LED 1 are made to be separated from each other. It may be fitted into a fitting hole formed in an umbrella. If the whole is made in one piece, the LED assembly 100 may be attached to the safety umbrella 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. 11 is a view showing that the LED assembly 100 is attached to the waterproof umbrella 280 of the safety umbrella by a high frequency attachment method. In addition, the portion where the LED assembly 100 is attached by the high frequency attachment method is attached to the inner shell which can cover the wires and the back of the LED assembly 100 so that the wires for connecting the LED assembly 100 to the inside of the umbrella do not protrude. It is preferable to have a structure.

Another attachment method is to make a plurality of fitting holes at regular intervals in the umbrella and to insert the LED assembly into the fitting holes. As a result, it is convenient to assemble the LED assembly 100 in the safety umbrella, and it is also convenient to replace the broken or problematic LED. To this end, the LED assembly 100 should have a concave shape at the bottom of the light transmitting portion. 12 illustrates another embodiment of an LED assembly. As shown in FIG. 12, in the LED assembly 100, there is a recess 40 in the lower portion of the light transmitting portion 10, which is coupled to the tarpaulin 280 of the umbrella to the side of the portion. The LED assembly 100 is made of a soft material is fitted to the fitting hole (285) formed in the waterproof cloth (280).

When the fitting hole 285 is formed in the umbrella, rainwater is infiltrated and wires for connecting the LED assembly to the inside of the umbrella are protruded. Therefore, attaching an inner shell to cover the wire and the back of the LED assembly 100 may be applied. It is desirable to solve the problem of rainwater seeping and wire protruding by attaching the outer shell to the part where the LED assembly 100 is attached to the conventional umbrella and forming the fitting hole in the outer shell to attach the LED assembly 100. .

On the other hand, when the light emitting unit 10 and the LED (1) is separated, as shown in Figure 13, the insertion hole 285 to the waterproof cloth 280, and the light emitting unit 10 on the upper portion of the fitting hole 285 For example, the LED 1 may be inserted into the lower portion of the fitting hole 285 by fitting from the lower portion to the upper portion to be combined with the light transmitting portion 10. In this case, the LED 1 and the light projecting portion 10 are brought into close contact and fixed. On the contrary, the LED 1 may be inserted into the lower portion of the fitting hole 285 and the light emitting part 10 may be coupled to the upper portion.

In this case, in order to increase the strength of the coupling, the support 50 may be additionally installed in the lower portion of the LED 1. 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. 14 is a cross-sectional view of the LED assembly in which the support is further installed. As shown in Figure 14, the support 50 is in close contact with the side of the light transmitting portion 10.

15 is a schematic view of an LED assembly with additional protective walls installed. As shown in FIG. 15, the diameter of the support 50 is larger than the diameter of the LED 1, and the support 50 is provided with a protective wall 52 for protecting the LED 1 around the LED 1. Can be. The protective wall 52 is formed in a circle around the LED 1 to prevent the LED assembly used in the present invention from being easily damaged by the external shock. The protective wall 52 does not necessarily need to wrap all around the LED 1 here.

In addition, the air of the portion C into which the LED 1 of the light emitting portion 10 is fitted is compressed as the LED 1 is inserted in the process of the LED 1 being fitted to the light emitting portion 10, and the LED is used for a long time. (1) was pushed by the compressed air, there was a problem that the LED (1) portion and the light transmitting portion 10 is separated. In the present invention, in order to solve this problem, it is possible to form an air discharge means in the light transmitting portion (10).

The air discharge means in the present invention includes an air discharge groove 18 or embossing (19). FIG. 16 is a cross-sectional view of the LED assembly in which two air discharge grooves are formed, and FIG. 17 is a cross-sectional view taken along the line AA of FIG. 16. As shown in FIG. 16 and FIG. 17, at least one groove is formed in the insertion direction of the LED 1 at a portion in contact with the LED 1 in the light transmitting part 10. The air discharge groove 18 serves to discharge the air inside the floodlight 10 to the outside in the process of fitting the LED (1).
