Description

[0001] MOBILE COMMUNICATION DEVICE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication apparatus and, for example, to an indoor mobile communication base station apparatus or a repeater apparatus.

A mobile communication service using wireless communication enables communication of individual subscribers through a base station installed by a service provider. The number and location of the base stations are determined according to the communicable area of the communication device. However, even if the number and position of the base stations are appropriately arranged, a shaded area in which a radio signal can not be obtained occurs. For example, some areas around the building may be shaded by tall buildings, and in the case of indoor, especially underground, wireless signals are difficult to reach, so if no additional base station device or repeater device is installed, The wireless communication may be impossible.

Therefore, the mobile communication service provider installs a small base station device or a repeater device in a building to provide smooth wireless communication. It is clear that in installing an indoor communication device, a cable for power supply must be connected from the switchboard to the communication device. Wiring in consideration of the installation of the communication device is often not performed in the indoor of the already completed building. In addition, even if wiring is performed in consideration of the installation of the communication device in the building, the location of the communication device is changed depending on the shade area, so that the already arranged wiring may not be utilized. Therefore, when the communication device is installed indoors, there is a risk that the power line or the like is wired in a state of being exposed to a wall surface or a ceiling, and there is a risk of damage, and the aesthetics of the interior are hindered. Further, it is possible to conceal and protect the power lines by using a separate molding, but there is a problem that the molding operation must be further performed.

Therefore, it is an object of the present invention to provide a mobile communication apparatus capable of preventing damage to a power supply line and the like, because it is possible to utilize a power supply line already installed while being installed indoors.

The present invention also provides a mobile communication device that is easy to install without hindering the aesthetics of the room.

The present invention also provides a mobile communication device capable of improving indoor aesthetics by being integrated with and hidden from an indoor lighting device while providing a wireless communication relay function.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 to 5, a mobile communication apparatus 102 according to a preferred embodiment of the present invention is incorporated in a lighting apparatus 101, and reference numeral 100 denotes a combination of a lighting apparatus and a mobile communication apparatus .

The lighting apparatus 101 includes a case 111 for accommodating a light source 137 and an illumination cover 115 for coupling to the case 111. [ The case 111 may have a part, for example, a front opening, and the lighting cover 115 may be coupled to the opening of the case 111. The illumination cover 115 may be fixed to the case 111 through a separate frame 113 or may be fixed to the case 111 by fastening means such as a screw or fixing means such as a binding lever And can be fixedly coupled to the case 111.

The light source 137 of the lighting device 101 may be a light emitting diode (LED), and may emit light for illumination through the opening of the case 111. When the light source 137 is a light emitting diode, a plurality of light emitting diodes may be arranged in the case 111 to form a surface light source, and a circuit board 131 for arranging the light emitting diodes may be formed in the light cover 115). In addition, a reflector 135 may be installed inside the case 111 for improving illumination efficiency. The light source 137 is disposed so as to face toward the inside of the case 111, for example, toward the reflection plate 135. When the reflection plate 135 is disposed inside the case 111, The cover 115 may be a transparent cover.

As the light source 137, any type of illumination lamp, such as a bulb type, a rod type, a coil type incandescent lamp or a fluorescent lamp, as well as a light emitting diode, . Depending on the shape of the light source 137, the shape of the case 111 and the like may be appropriately modified.

5, the circuit board 131 may include a plurality of openings 133 so that light reflected from the reflector 135 may travel to the illumination cover 115, as illustrated by a plurality of arrows. can do. When a plurality of openings 133 are formed in the circuit board 131, the circuit board 131 will have a substantially lattice shape. In addition, the narrower the width between the opening 133 and the opening 133 is, so that the shadow of the circuit board 131 in the form of a lattice is not exposed, is more preferable. Therefore, the circuit board 131 can be manufactured in the form of a mesh. In some embodiments, the circuit board 131 may be attached to the illumination cover 115, e.g., a transparent cover.

5, the reflection plate 135 is spaced apart from the inner surface of the case 111. However, the reflection plate 135 may be attached to the inner surface of the case 111. As shown in FIG.

The light source 137 may be arranged so that the light emitting direction of the light source 137 is directed toward the outside of the case 111 regardless of whether the reflection plate 135 is installed or not, And the illumination cover 115 transmits the light reflected from the reflection plate 135 or emitted from the light source 137. At this time, the illumination cover 115 may be made of a transparent material or a semi-transparent material. When the light emitted from the light source 137 travels directly to the illumination cover 115 without passing through the reflection plate 135, the illumination cover 115 may be a translucent material diffusion cover. For example, it is possible to improve the glare caused by the light emitting of the light source 137 by using the illumination cover 115, and transmit the light uniformly over the entire area of the illumination cover 115.

The mobile communication device 102 includes at least one communication device portion disposed on the back surface of the lighting device 101 and more specifically disposed on the outer surface of the case 111 opposite to the opening portion of the case 111 And an antenna element 129b having a radiating direction at the opening of the case.

The communication unit includes a power amplifier module (PAM) 121, a digital interface module (DIM), an up-converter (UDC) integration module 125, an antenna element 129b and a direct current converter (DC DC) 127 and a frequency filter 123. The amplifier module 121 may be provided in a plurality of units. In this case, the plurality of amplifier modules 121 may be disposed at positions spaced apart from each other. The communication unit may be powered by a power supply, for example, a switching mode power supply (SMPS) 119 provided in the lighting apparatus 101. [ The switched mode power supply 119 is a power supply for the lighting device 101 but is capable of providing power to the components of the mobile communication device 102.

The amplifier module 121, the digital interface module and the up-down converter integration module 125, the DC power converter 127 and the frequency filter 123 are disposed adjacent to each other on the back surface of the case 111, By engaging the cover 128, it is concealed and protected without being exposed to the external environment.

The antenna element 129b of the mobile communication device 102 may be disposed inside or outside the case 111 while being supplied with power through the communication circuit portion.

In the structure in which the mobile communication device 102 is installed in the case 111 itself, the antenna element 129b may be disposed inside the case 111. [ The receiving groove 117b formed in the case 111 can receive the antenna element 129b. The reflection plate 135 may be disposed between the receiving groove 117b and the light source 127 to cover the receiving groove 117b and the antenna element 129b.

The case 111 is formed with a protrusion 117a communicating with the inside of the case 111 while protruding from the outer surface of the case 111. The protrusion 117a is formed on the case 111 on the inside of the protrusion 117a, (117b) are formed. The receiving groove 117b may be opened to the inside and the backside of the case 111, respectively. 5, the receiving groove 117b is closed by the support plate 129a on which the antenna element 129b is disposed, and on the inner side of the case 111, The receiving groove 117b can be concealed or closed by the engaging portion 135. [ Here, the support plate 129a may be used as a radio frequency reflector for radio waves transmitted to and received from the antenna element 129b while providing a means for mounting the antenna element 129b to the case 111 . The support plate 129a is coupled to the protrusion 117a such that the antenna element 129b faces the inside of the case 111. [

The communication circuit unit and the antenna element 129b may be provided on the back surface of the case 111 in a detachable manner. 6 illustrates a configuration in which the mobile communication device 102 and the switching mode power supply 119 are detachably provided in the case 111. [ The mobile communication device 102 may be provided with an antenna case 117c corresponding to the protrusion 117a of the preceding embodiment. When the mobile communication device 102 and the switching mode power supply 119 are detachably connected to the case 111, spacers 141 may be disposed on the outer surface of the case 111. The spacers 141 can secure a predetermined interval between the mobile communication device 102 and the case 111 and between the switching mode power supply 119 and the case 111. [ As a result, the mobile communication device 102 and the switch mode power supply 119 are opposed to the outer surface of the case 111 with the spacers 141 interposed therebetween. Thus, heat transfer to the case 111 can be suppressed while smoothly discharging heat generated from the mobile communication device 102 and the switching mode power supply 119. The amplifier module 121 or the like constituting the communication circuit part may be uniformly distributed on the outer surface of the case 111. [

Meanwhile, the antenna case 117c may be detachably provided in the case 111 while receiving the antenna element 129b. In this case, although the support plate 129a of the preceding embodiment is not necessarily required, a radio wave reflector that reflects the radio wave radiated from the antenna element 129b may be provided in the antenna case.

As described above, if the mobile communication device 102 is configured to be removable from the case 111, it is easy to install the mobile communication device 102 at the appropriate place. For example, the wireless communication environment can be improved by connecting the mobile communication apparatus 102 to the case 111 and expanding the communication relay facility at a place where the lighting apparatus having the case 111 is already installed .

The structure of the embodiment shown in Fig. 5 exemplifies a structure of an indirect illumination system in which light emitted from the light source 137 is reflected by the reflection plate 135. [ However, the present invention is not limited thereto. For example, as described above, the present invention can be implemented by a direct illumination type structure in which light emitted from the light source 137 is directly transmitted through the illumination cover 115. This configuration is shown in Fig. In this case, the reflector 135 of the preceding embodiment is not necessarily installed. However, a screen or the like for concealing the receiving recess 117b may be installed inside the case 111. [ In addition, as described above, if the structure is a direct illumination type, the illumination cover 115 may be made of a translucent material to serve as a diffusion cover.

Figs. 8 and 9 show a combined body 200 in which the mobile communication device 102 according to another preferred embodiment of the present invention is incorporated in the lighting device 201. Fig. The mobile communication apparatus 102 according to the present embodiment has a structure in which the antenna element 129b is disposed in the lighting apparatus 201 of the direct illumination type, Which is different from the communication device of the embodiment shown in Figs. 1 to 5. In addition, the arrangement of the amplifier module, the digital interface module, the up-down converter, the DC power converter, the frequency filter, and the switching mode power supply may be somewhat different from each other in the back surface of the lighting apparatus. However, I can understand it. Therefore, in describing the present embodiment in detail, it is noted that a detailed description of a configuration that can be easily understood through the preceding embodiments may be omitted. It is noted that the same reference numerals are used to denote the same or similar components as those of the preceding embodiments, and detailed descriptions thereof may be omitted.

In the mobile communication device 102 according to the present embodiment, the antenna element 129b is disposed inside the case 211. [ The antenna element 129b may be in the form of a partially bent wire. At this time, the circuit board 131 on which the light sources 137 are arranged may be disposed at a position spaced apart from the inner surface of the case 211. In this case, even if the antenna element 129b is disposed inside the case 211, it may be positioned between the circuit board 131 and the inner surface of the case 211. The antenna element 129b is disposed at a position deviated from the path of the light emitted from the light sources 137 inside the case 211. Therefore, The shadow will not be exposed to the outside.

In addition, the wire-shaped antenna element 129b may be disposed between the light sources 137 on the front surface of the circuit board 131. 10 and 11 illustrate a configuration in which a wire-shaped antenna element 129b is disposed on the front surface of the light sources 137 in a direct lighting type lighting apparatus. The antenna element 129b is connected to the circuit board 131 through one of the openings 133. The circuit board 131 is connected to the circuit board 131 through the opening 133, Can be extended through. The antenna element 129b may be bent at the front surface of the circuit board 131 so that at least a portion of the antenna element 129b may be positioned between the circuit board 131 and the illumination cover 115. [ A part of the antenna element 129b is preferably disposed between the circuit board 131 and the illumination cover 115 and between the light sources 137. [

Such communication devices may be provided in an integrated state or detachably in a lighting apparatus. In other words, even if the communication device according to the present invention is not integrated with the lighting device, it is possible to sell and construct the integrated lighting devices themselves, and if necessary, The environment can be improved. Further, since the power of the communication devices can be supplied through the power supply of the lighting device, no separate wiring for power supply is required.

Moreover, since the luminaire is installed between the wall of the room or the ceiling finishes, it is possible to separate some of the laminates around the luminaire on the wall or ceiling where the luminaire is installed and to install the communication device inside the ceiling.

12 is a cross-sectional view showing a modified example of the communication device shown in Fig. 10, in which a communication device is integrated into a lighting device having a structure similar to that of Fig. 10 and indirectly illuminated by way of, for example, Respectively.
