Therefore, the scope of the present invention should not be construed as being limited to these embodiments.

[Lighting Mirror]

Example 1

FIG. 3 is a view for explaining an illumination mirror 130 according to the first embodiment of the present invention. As shown in Fig. 3, the illumination mirror 130 includes a reflection plate 132, a light guide portion 133, and an LED light source (not shown).

A reflecting surface 132a is formed on the upper surface of the reflecting plate 132. The light guiding unit 133 is installed such that at least a part of the reflecting surface 132a is exposed. And is disposed around the outer periphery of the reflection plate 132.

The LED light source is installed to irradiate light to the light guiding part 133. Since the installation of the LED light source is well known in the field of LED backlight, its illustration and description are omitted.

3, since the reflection plate 132 serves as a mirror, it is not necessary to install a separate mirror as in the conventional case. Since the reflection plate 132 is illuminated brightly through the light guiding unit 133, The mirror 132 can be used as a mirror.

Example 2

4 is a view for explaining the illumination mirror 130 according to the second embodiment of the present invention. Unlike the case of FIG. 3, the light guide portion 133 is provided on the reflection surface 132a at the edge of the reflection plate 132 So that a part of the reflecting surface 132a, not the entire surface, is exposed.

Thus, the light directed downward from the light guiding portion 133 is reflected by the reflecting surface 132a located directly below the light guiding portion 133 and is directed forward, thereby improving the illumination effect.

3 and 4, since the light guiding portion 133 is located higher than the reflecting surface 132a, the light emitted from the light guiding portion 133 is also directed toward the reflecting surface 132a serving as a mirror, When the mirror 132 is viewed as a mirror, glare may occur, which may be somewhat inconvenient.

Example 3

5 and 6 are diagrams for explaining the illumination mirror 130 according to the third embodiment of the present invention. In FIGS. 3 and 4, the inner side of the light guide portion 133 facing the reflection surface 132a And a light shielding part 139 is further provided on the side surface. Therefore, the light emitted from the light guiding portion 133 is blocked by the light blocking portion 139 and can not directly go to the reflection surface 132a, so that the glare phenomenon shown in FIGS. 3 and 4 is prevented.

Example 4

3 and 4, in order to prevent the glare phenomenon that may occur in FIGS. 3 and 4, the light guiding portion 133 is provided on the reflection plate 132, And is installed so as not to protrude above the reflecting surface 132a.

Since the light emitted from the light guiding portion 133 is blocked by the side surface of the reflection plate 133 and can not be directed toward the reflection surface 132a, the glare effect on the reflection surface 132a can be prevented.

Example 5

8 is a view for explaining the illumination mirror 130 according to the fifth embodiment of the present invention. In the configuration of FIG. 7, a light blocking protrusion 239 is formed at a boundary portion between the light guide portion 133 and the reflection surface 132a Is further formed. The light emitted from the light guiding portion 133 is blocked by the light intercepting protrusion 239 and can not directly go to the reflection surface 132a, so that the glare phenomenon shown in FIG. 7 is prevented.

Example 6

9 is a view for explaining an illumination mirror 130 according to a sixth embodiment of the present invention. Fig. 9 also shows that the case of Fig. 7 is further improved to provide not only an anti-glare effect but also an excellent lighting effect.

The inclined upper inclined surface 232 is formed on the side surface of the reflection plate 132 so as to obliquely face upward and the inclined downward inclined surface 233 is formed on the side surface of the light guiding portion 133 so as to obliquely look downward, And the downward inclined plane 233 is seated on the upper inclined plane 232.

Since the light emitted from the light guiding portion 133 is reflected toward the front side by the upward inclined surface 232 facing the side surface of the reflection plate 133, the illumination effect by the light guiding portion 133 is further improved. At this time, if the reflecting surface 232a is formed on the upward sloping surface 232, such an effect is further developed, which is preferable.

The reflecting surface 232a formed on the upper inclined surface 232 may be provided separately from the reflecting surface 132a of the reflecting plate 132. However, it is preferable that the reflecting surfaces 132a and 232a are simultaneously formed Do.

Example 7

10 is a view for explaining an illumination mirror 130 according to a seventh embodiment of the present invention. The difference from FIG. 9 is that an upward inclined surface 232 is formed on the upper surface edge of the reflector 132, The reflecting surface 132a formed on the upper surface of the reflecting mirror 132 is used as it is.

[Cosmetic case]

FIGS. 11 and 12 are views for explaining the cosmetic case 101 according to the present invention, in which the illumination mirror 130 of FIG. 7 is applied.

11 and 12, the cosmetic case 101 includes a main body 110 and a lid 120, and the lid 120 is hinged to the main body 110 so as to be opened and closed. The main body 110 contains cosmetics 111 and the lid 120 is provided with the illumination mirror 130 according to the present invention.

The illumination mirror 130 is preferably installed in the concave receiving portion of the lid 120 so that the illumination mirror 130 keeps the fixed state without shaking when the cosmetic case 101 is carried, It is preferable that a fixing frame 121 for pressing the rim of the illumination mirror 130 is installed at the entrance of the concave accommodation portion so that the concave accommodation portion 130 is not detached from the concave accommodation portion.

Fig. 13 is a view for explaining the illumination mirror 130 and a method of manufacturing the same, with respect to the illumination mirror 130 of Fig.

13, the illumination mirror 130 includes a light guide portion 133, a diffusion sheet 135, and prism sheets 136 and 137 sequentially stacked as an upper layer on the reflection plate 132, And an FPC-LED 134 is provided at the edge of the light emitting diode 133.

The light emitted from the FPC-LED 134 spreads laterally through the light guiding portion 133 and then is emitted upward or downward. Since the light emitted downward is reflected upward by the reflection plate 132, The light is directed upward with the diffusion sheet 135 therebetween.

As the light guiding portion 133, a resin such as polycarbonate (PC) or PMMA (Poly Methyl Methacrylate Acrylate) may be selected.

The reflection plate 132 is formed by coating a high reflective material such as silver or titanium oxide on a base material such as stainless steel (SUS), brass, aluminum (Al), PET, .

The diffusion sheet 135 is formed on the light guiding portion 133 so that the pattern of the light guiding portion 133 is canceled because the pattern of the light guiding portion 133 is directly exposed when the light scattered by the light guiding portion 133 enters directly into the eye. . As the diffusion sheet 135, it may be selected that a polymer material is used as a base and a small diffusion pigment of several micro-units is mixed on both sides thereof.

It is preferable that the prism sheets 136 and 137 are provided on the diffusion sheet 135 in order to increase the light brightness by concentrating the light again because the brightness of the light falls sharply beyond the diffusion sheet 135. [ As the prism sheets 136 and 137, strip type micro prisms may be formed on base materials such as PET or the like, and they may be referred to as reference numerals 136 and 137, It is preferable to use two sheets as one set.

A frame 131 is provided for fixing the reflection plate 132, the light guide portion 133, the diffusion sheet 135, and the prism sheets 136 and 137. A double-sided tape 138 may be provided on the top of the top prism sheet 137 for attaching the illumination mirror 130 to the fixing frame 121 of the cover 120.

The upper layer, that is, the light guide portion 133, the diffusion sheet 135, and the prism sheets 136 and 137 on the reflection plate 132 are formed on the reflection plate 132 so that the reflection plate 132 can serve as a mirror, An opening A is formed.

The opening A is formed by stacking the light guide portion 133, the diffusion sheet 135 and the prism sheets 136 and 137 on the reflection plate 132 and then leaving the reflection plate 132 thereon, The diffusing sheet 135 and the prism sheets 136 and 137 may be formed by sequentially laminating the light guide portion 133, the diffusion sheet 135 and the prism sheets 136 and 137, It may be laminated on the reflector 132. FIG.

A transparent protective sheet (not shown) may be further provided on the prism sheet 137 to protect the illumination mirror 130 from external environments such as moisture, powder, dust, etc. In this case, the double- And the protective sheet is not provided with an opening.

 13, the diffusion sheet 135 and the prism sheets 136 and 137 are laminated on the light guiding portion 133 for improving the illumination effect, which is not only in the structure of the second embodiment (Fig. 4) The same can be applied to the embodiment.

14 is a diagram for explaining the arrangement relationship of the light guide portion 133 and the reflection plate 132. Fig. The light guide 133 and the reflection plate 132 may be arranged in various forms as shown in FIG. 14, as shown in FIG. 13, although the light guide 133 may surround the reflection plate 132 .

As described above, according to the present invention, since the light guiding portion 133 serves as a light source and the reflection plate 132 directly serves as a mirror, it is not necessary to provide a separate mirror. Further, since the light guiding portion 133 is used, there is an advantage that sufficient illumination effect can be obtained even with a small number of LED light sources. It is very useful that only a small number of LEDs can be installed in consideration of the fact that the compact cosmetic case is limited in size so that it is easy to carry and is very limited in space. Also, since the battery consumption is low and the battery replacement cycle is long, the convenience of use is also great.

[Surface light lamp]

15 to 29 are views for explaining various types of surface-emitting lamps that can be used as an illumination mirror according to the present invention.

15 is a structural view of the surface-emitting lamp 2 according to the first embodiment of the present invention. 15, the surface-emitting lamp 2 according to the present embodiment may include a printed circuit board 206, a plurality of LED light sources 200, a silicon cover 300, and a diffusion material 400 have.

The printed circuit board 206 may provide one surface of the printed circuit board 206 as a mounting surface of the LED light source. A circuit pattern can be printed for electrical connection between the mounted LED light sources. The printed circuit board 206 may be formed by forming a circuit pattern on the FR4 substrate, exposing a terminal for mounting the LED light source and other elements, and then covering the circuit pattern with a resist film. In addition, the printed circuit board may be embodied as a flexible substrate.

The printed circuit board 206 may include a substrate 201, a printed circuit layer 202, and a resistor layer 203. That is, the printed circuit board 206 includes a circuit pattern 202 formed on the FR4 substrate 201 and a resistor layer 203 covering the circuit patterns except for the LED mounting area of the circuit pattern 202 can do. The LED light source 200 may be mounted on the LED mounting region. Although the present embodiment has been described with reference to a classical printed circuit board, the present embodiment can also be applied to a flexible printed circuit board (FPCB).

In the present embodiment, the reflector 204 may be formed on all or a part of the printed circuit board 206. That is, by forming the reflector 204 in the area where the LED light source 200 is not mounted on the printed circuit board 206, the light emitted from the LED light source 200 is reflected upward, .

In more detail, a reflector 204 may be formed on the resistor layer 203 of the printed circuit board 206. Here, the reflector 204 may be formed by depositing aluminum (Al). In this embodiment, an aluminum layer is formed on the surface of the printed circuit board 206, so that the light emitted from the LED light source 200 can be reflected upward of the printed circuit board 206.

On the other hand, as shown in FIG. 16, a reflection pattern 205 may protrude from the reflector 204. The reflection pattern 205 may be formed of Ni / Ag using a printing process. When the reflective pattern is formed by using the printing process, the process can be simplified as compared with the case of attaching a separate pattern film. Since the reflective pattern 205 may have a predetermined gap and may have a predetermined height, the reflective pattern 205 may reflect light emitted from the LED light source 200 toward an upper portion of the printed circuit board. have.

The reflection pattern 205 may be formed in a shape having a slope in one direction. That is, the cross-section of the reflection pattern may be formed in a triangular shape having a slope in one direction larger than a slope in the other direction. By doing so, the reflection efficiency can be further increased.

17, the LED mounting printed circuit board 206 according to the present embodiment may include a reflector layer 204 and a reflection pattern 205a provided on the printed circuit board 206 . The reflective pattern 205a of this embodiment differs from the embodiment of FIG. 16 in that the reflective pattern is formed of an irregular concave-convex structure.

Here, the irregular concavo-convex structure may be a form in which the concavo-convex pattern is not formed at regular intervals as shown in FIG. That is, not only the shape of the irregularities is irregular as in the drawing but also the irregular arrangement of the irregularities can be included. Such an irregular reflection pattern may also be formed into a discontinuous point shape. Such irregular protrusions and depressions can be formed in a manner known to those skilled in the art, such as printing, deposition, printing, or post-deposition grinding.

The LED light source 200 may be an LED package. The LED light source may be a sideview type LED package. By using the side view type LED package, it is possible to prevent the point light source from appearing on the light emitting surface of the surface light emitting lamp according to the present embodiment. Although the side view type LED package is illustrated in this embodiment, the LED light source 200 may be implemented in various forms such as a lens type, a COB type, and the like.

18, the LED light source 200 may include an LED element 210 mounted on a printed circuit board 206 and a lens 220 covering the LED element 210. Referring to FIG.

The LED element 210 may be an LED chip. For example, when a COB (Chip On Board) type LED lamp is manufactured, an LED chip is directly mounted on a substrate, and the LED chip is covered with a lens. In this case, an LED chip can be used. In this case, a phosphor for white light conversion may be included in the lens. At this time, the LED chip is mounted on the substrate by wire bonding or flip chip bonding, and the lens covering the LED chip can be formed by an injection process.

The LED element 210 may be an LED package in which the LED chip is mounted in the housing. In the LED package, an LED chip is mounted by wire bonding or flip chip bonding, and a molding part covering the LED chip may be formed.

In this embodiment, the center portion may be a point shape. The LED element 210 is positioned below the center portion. The light characteristics depending on the light emitting direction may appear differently due to the characteristics of the LED device, so that the light uniformity from the outside may be deteriorated. In order to compensate for this, it is possible to improve the external light uniformity by changing the shape of the lens to match the light emitting characteristic. In the present embodiment, the thickness of the lens directly above the LED element is made thinner and the thickness of the lens at the upper side is made relatively thick, so that the light uniformity can be improved.

A fine pattern may be formed on the surface of the lens 220. The fine pattern may be formed in a concavo-convex shape on the surface of the lens. In the case of forming a fine pattern, the light reflected to the inside of the lens can be extracted to the outside of the lens by total reflection caused by the flat surface of the lens, so that the dispersion of the light emitted from the lens surface can be further extended. The shape and arrangement of the fine patterns may be variously embodied.

19 is a sectional view of an LED light source according to another embodiment of the present invention. Referring to FIG. 19, the LED light source 200 according to the present embodiment may further include a light diffusing agent 230 inside the lens 220. The light diffuser 230 may diffuse the light emitted from the LED 210.

As the light diffusing agent 230, at least one selected from titanium oxide, titanium oxide, aluminum oxide, silicon oxide, zinc oxide, metal pieces or phosphors may be used. Although the light diffusing agent 230 and the phosphor 240 are both included in the present embodiment, the light diffusing agent 230 may be used alone or only the phosphor may be used according to the embodiment.

20A and 20B illustrate a fine pattern provided on the surface of the lens 220 in the LED light source 200 according to another embodiment of the present invention.

20 (a), the fine pattern 223 formed on the surface of the lens 220 may be formed in a concentric shape centered on the central portion 221 of the lens 220. As shown in FIG. Although only a few concentric circular shapes are shown in this figure, they may be arranged in a more compact form in actual products.

The fine pattern 223 formed on the surface of the lens 220 may be formed in a shape extending radially from the center 221 of the lens 220, as shown in FIG. 20 (b). Although only a few lines are shown in this drawing, they may be arranged in a more compact form in an actual product. In another embodiment, the concentric and radial shapes may be combined.

21 is a perspective view of an LED light source 200a according to another embodiment of the present invention. Referring to FIG. 21, the LED light source 200a according to the present embodiment includes the LED element 210 mounted on the printed circuit board 206, and a lens 220a covering the LED element is formed.

The LED element 210 may be an LED chip. For example, when a COB (Chip On Board) type LED lamp is manufactured, an LED chip is directly mounted on a substrate, and the LED chip is covered with a lens. In this case, an LED chip can be used. In this case, a phosphor for white light conversion may be included in the lens. At this time, the LED chip is mounted on the substrate by wire bonding or flip chip bonding, and the lens covering the LED chip can be formed by an injection process.

The LED element 210 may be an LED package in which the LED chip is mounted in the housing. In the LED package, an LED chip is mounted by wire bonding or flip chip bonding, and a molding part covering the LED chip may be formed. When the LED package is used, a phosphor for white light conversion may be included in the molding part inside the package.

The lens 220a may have a shape in which the center of the upper surface is concave and the peripheral portion thereof is convex. The lens according to the present embodiment is different from the embodiment shown in Fig. 18 in that the central portion 221a is linearly formed and can be formed symmetrically about the central portion. In other words, the lens 220a may be configured such that two hemispherical lenses 222a and 222b are partially overlapped with each other. The LED element 210 is positioned below the center portion. The light characteristics depending on the light emitting direction may appear differently due to the characteristics of the LED device, so that the light uniformity from the outside may be deteriorated. In order to compensate for this, it is possible to improve the external light uniformity by changing the shape of the lens to match the light emitting characteristic. In the present embodiment, the thickness of the lens directly above the LED element is made thinner and the thickness of the lens at the upper side is made relatively thick, so that the light uniformity can be improved.

The lens 220a of the LED light source according to the present embodiment may have a shape in which both sides thereof are removed in the longitudinal direction. The scattering angle of the light emitted from the LED element 210 can be adjusted by the lens formed in the longitudinal direction. In this embodiment, the angle of scattering along the longitudinal direction of the lens can be wider than the angle of scattering along the width direction of the lens. The shape of the lens 220a may vary depending on the use of the surface light source lamp, and the radiation angle of the light can be controlled by cutting off both sides in the longitudinal direction as in the present embodiment.

22 is a conceptual diagram showing a fine pattern formed on the LED light source 200a according to another embodiment of the present invention. The fine pattern may be formed in a concavo-convex shape on the surface of the lens. In the case of this embodiment, by forming a fine pattern on the surface of the lens, the light uniformity can be improved as compared with the case where there is no fine pattern.

22 (a) shows a shape in which the fine pattern 223a is formed only in the central region of the lens 220a. Since the LED element 210 is positioned below the central portion of the lens 220a, light can be emitted most strongly from the LED element 210. FIG. Therefore, the intensity and uniformity of light can be improved by forming the fine pattern 223a at the center of the lens, which is the lens portion of the region where the LED element 210 is located, as in the present embodiment.

22 (b) shows the fine pattern 223a formed on the entire surface of the lens. A fine pattern can be uniformly formed on the entire side surface as well as the top of the lens. By forming the fine pattern, the intensity and uniformity of light emitted from the lens 220a can be improved. The size and shape of the fine pattern may be variously embodied.

23 (a) and 23 (b) are experimental examples for explaining the effects of the LED light sources 200 and 200a according to the present invention.

23 (a) shows light output in the state where no fine pattern is formed on the surface of the lens according to the embodiment of Fig. 18, and Fig. 23 (b) And the light output was measured in a state of being formed. 23A and 23B, the light outputs (PKG X and PKG Y) emitted from the LED elements are the same, but the light outputs (lens X and lens Y) emitted through the lens form a fine pattern It can be seen that the directivity angle is reduced and the uniformity of light is improved as compared with the case where one case is not formed.

The silicon cover 300 may be formed to cover the printed circuit board 206 and the LED light sources 200 and 200a. And the LED light sources 200 and 200a. The silicon cover 300 is transparent or semitransparent and can transmit light emitted from the LED light sources 200 and 200a.

The process of forming the silicon cover 300 on the printed circuit board 206 may include a step of inserting a printed circuit board into a jig and pouring liquid silicon to cure the printed circuit board to a predetermined frame. By using the liquid silicone in this way, the surface-emitting lamps 2 of various shapes can be formed.

In this embodiment, the printed circuit board 206 may be fabricated in the form of a surface light source lamp to be actually formed, and the silicon cover 300 may be formed in the form of a printed circuit board. In this embodiment, since the silicon cover 300 is manufactured by pouring liquid silicon in the process of manufacturing the silicon cover 300, the shape of the light emitting surface of the surface light source lamp 2 can be freely implemented.

The silicon cover 300 may be manufactured in a transparent or translucent state. In the case of using transparent silicon, the light transmittance is good, but since the LED light source inside is visible, it may not be visually good. Conversely, when translucent silicon is used, an internal LED light source may not be visible.

The material of the silicon cover 300 may be selected depending on the use of the surface-emitting lamp. That is, in the case of a decorative or indicating lamp which does not require a large luminous intensity, it is preferable to use a translucent silicone material.

The diffusion material 400 is dispersed in the silicon cover 300. The diffusing member 400 may increase light extraction efficiency of the surface-emitting lamp 2 by dispersing light traveling in the silicon cover 300. In the manufacturing process, it is possible to follow a step of mixing the diffusion material 400 with the liquid silicon, and pouring the liquid silicon mixed with the diffusion material into a jig (JIG).

In the present embodiment, the silicon cover 300 is made of a moldable silicone, and the diffusion material 400 to be mixed therewith may be aluminum oxide. In the present embodiment, the molybdenum silicon and aluminum oxide may be mixed at a ratio of 80:20 to form a liquid silicone, which is then cured to form the silicon cover.

The light emitted from the LED light source 200 is dispersed through the diffusion material 400 dispersed in the silicon cover 300 while passing through the silicon cover 300. In this case, By using this property, a surface-emitting lamp having a shape that emits light from the entire light-emitting surface of the silicon cover 300 can be formed.

Fig. 24A is a step of mounting the LED light source 200 on the printed circuit board 206. Fig. In this case, the LED light source 200 may be an LED package of a side view type. A reflector 204 may be formed on a portion of the printed circuit board 206 where the LED light source is not mounted. As the printed circuit board 206, a flexible board may be used.

24 (b) is a step of positioning the printed circuit board 206 on the jig 207. FIG. The jig 207 can take out the liquid silicone so that a silicon cover having a desired shape is formed when the liquid silicone is poured and hardened.

24C is a step of applying liquid silicon containing the diffusion material 400 to the jig 207 on which the printed circuit board 206 is placed. In this step, the liquid silicone can be applied so as to cover the printed circuit board 206 and the LED light source 200. The height of the applied silicon should be higher than the mounting height of the LED light source 200.

24 (d) is a step of forming the silicon cover 300 by curing the applied liquid silicone. When the silicon is cured in this step, the surface emitting lamp can be formed by removing the jig.
