The power source 310 may be, for example, a battery, a battery And the like. A reflective layer may be formed on the surface of the power source 310 to reflect light. The reflective layer may be formed of a film or the like. The first module 320 includes a first substrate 323 and at least one semiconductor light emitting device 322 provided on the first substrate 323. For example, the first substrate 232 may be a circuit board. The first module 320 is provided on the lower side of the power source 310 and the first module 320 and the power source 310 are electrically connected. The first module 320 may include a MICOM, a battery charging circuit, a transistor, a switch, a connector, and the like.

The second module 330 includes at least one semiconductor light emitting device 332 provided on the second substrate 334 and the second substrate 334. [ For example, the second substrate 334 may be a circuit substrate, and the semiconductor light emitting device 332 may be an LED. The second module 330 is located on the top surface of the power source 310 and is electrically connected to the power source 310.

The illumination device may further include a diffusion cover 200 surrounding the first module 320 and the second module 330. The diffusion cover 200 diffuses light and can be formed of a diffusion material. For example, the diffusion cover 200 may be formed of a diffusion PC (Polycarbonate). In addition, the illumination device may further include a translucent character feature 100 surrounding the diffusion barrier 200. The character shape 100 may be formed of PE, PVC, PP, or the like. The character shape 100 is not limited to a character but includes objects and figures.

For example, the power source 310 may be connected through a connection unit 311 that electrically connects the power source 310 and the first module 320, and the second module 330 may be connected to the second module 330, 1 module 320 through a connection portion 331 that electrically connects the module 320 to the power source 310. [

4 is a view showing another example of a lighting apparatus according to the present disclosure.

4 shows a diffusion cover 200 covering the first module 320 and the second module 330, respectively. The diffusion cover 200 may cover at least one of at least the first module 320 and the second module 330. The light of the semiconductor light emitting device 322 of the first module 320 is spread by the diffusion cover 200 and the light of the semiconductor light emitting device 332 of the second module 330 is also diffused into the diffusion cover 200 It spreads evenly. Particularly, due to the semiconductor light emitting elements 322 and 333 of the first module 320 and the second light emitting element 332 of the second module 330, the first module 320 and the second module 330, The light from the module 330 can be bright. By using the diffusion cover 200, the light path can be changed little by little to uniformly spread the light.

5 is a view for explaining a diffusion cover according to the present disclosure;

5 (a) shows a character shape 100 and a diffusion cover 200 formed in a conventional illumination device, and Fig. 5 (b) shows a character shape 100 and a diffusion cover 200 according to the present disclosure FIG. The diffusion cover 200 of FIG. 5 (a) is formed to cover the first module 320 at one time from top to bottom. Light from the first module 320 is diffused and diffused by the diffusion cover 200 and the diffusion cover 200. However, the semiconductor light emitting device 322 of the first module 320 is located at the lower portion of the diffusion cover 200 so that the lower portion is bright and the upper portion is dark. Particularly, It is hard to tell.

The diffusion lid 200 of Figure 5B includes a portion 202 covering the first module 320, a portion 201 covering the second module 330 and a portion 202 covering the first module 320, And a portion 203 covering the power source 310 connecting the portion 201 covering the second module 330. The first module 320, the second module 330 and the power source 310 are simultaneously wound and the portion 202 covering the first module 320 and the portion 201 covering the second module 330 are connected to each other The diameter of the portion 203 covering the power supply 310 among the portions 203 covering the power supply 310 is small so that the diffusion lid 200 covers the first module 320 from top to bottom as shown in FIG. It is not possible to fabricate the diffusion cover 200 of FIG. 5 (b), so that it is preferable to fabricate and connect the left cover 211 and the right cover 212. The diffusion cover 200 has a left cover 211 and a right cover 212 and is joined by a left cover 211 and a right cover 212. [

The diffusion cover (200) includes a curved portion (220). The bent portion 220 can be formed around the semiconductor light emitting element and can control the direction in which the light is directed. The first module 320 provided on the lower surface of the power source 310 and the second module 330 provided on the upper surface of the power source 310 may be provided with the diffusion cover 200 as shown in FIG. In the character shape (100) like 3, it is difficult to evenly illuminate the arms and legs. Because arms and legs are long and thin, most of the light goes out before the light reaches the extremities of the arms and legs. Therefore, it is desirable to refract the light so that the light can be directed to the darkened part. The light passes through the bent portion of the diffusion cover 200 and changes the direction of the light as indicated by an arrow. As a result, more light can reach a long, thin-shaped part, and the dark part can be illuminated.

The second module 330 positioned in the direction of the top surface of the power source 310 can appropriately adjust the position through the inner circumferential surface 351 of the second substrate 334 as in the second module described with reference to FIG. As a result, an adjustable distance d between the first module 320 and the second module 330 can be formed.

As shown in FIG. 7 (b), the angle formed between the second module 330 and the power source 310 can be adjusted according to the shape of the character. Accordingly, a certain distance may be formed between the first module 320 and the second module 330. For example, as shown in FIG. 7 (b), one of the second module 330 and the first module 320 has a distance d1, and the other has a distance d2.
