Description

Technical Field

[0001] The present invention relates to a table lighting device installed on a table so as to be able to remove a shadow formed on an illumination object such as a subject or a speaker. More specifically, the present invention relates to a table lighting device that supplies illumination toward the shadow of an illumination object so as to be able to remove a shadow formed around the neck of the illumination object by ceiling lighting attached to an indoor space for photographing an image of a subject like a studio or a space for a speaker like a stage.

Background Art

[0002] With the development of the Internet, the number of cases where many people post their own photos and videos on the Internet has increased. In such a situation, one-person broadcasts that produce content alone are explosively increasing worldwide while presenting various revenue structures such as a system that creates revenue by using advertisements that appear when a video is played.

[0003] In particular, multi-channel networks (MCNs) have been developing online one-person broadcasts as sustainable businesses. Creators are developing various video contents in order to obtain more subscribers and are working hard to obtain good equipment and excellent editing techniques. Some video content producers who are active as creators on the most popular YouTube (registered trademark) may earn more in a month than the annual income of an ordinary company employee.

[0004] For shooting a video, which is the basis of such video content production, a camera and a lighting device are required. Basically, the camera is fixed to a tripod holder or fixed using a gimbal, and the lighting device mainly uses basic lighting attached to the ceiling and, if necessary, additional lighting is installed in front of the illumination object.

[0005] In particular, among the many factors that affect the quality of a video of a subject being photographed, the most important and influential one is lighting. Depending on the position of the lighting device that provides lighting to the subject, videos of very different qualities can be generated.

[0006] On the other hand, with the development of the online environment, it has become possible to watch real-time religious ceremonies, weddings, lectures, etc. through videos. Generally, for general lighting installed, lighting fixtures are uniformly arranged on the ceiling surface, and side lighting fixtures are installed on both sides so that the ratio of the maximum illuminance to the minimum illuminance on the stage floor and space does not exceed 3:1.

[0007] FIG. 1 and FIG. 2 are schematic views showing the shadows formed on the lighting object when lighting is irradiated toward the table.

[0008] When using general lighting in this way, there is a problem that shadows are formed around the neck of the speaker, interfering with the concentration of viewers and the audience.

[0009] At present, in order to enhance the visual effects of viewers and the audience and improve the quality of video content, there is a demand for the development of a device that prevents a shadow S from being formed on the body of a creator or speaker who is the object of lighting irradiation.

Summary of the Invention

Problems to be Solved by the Invention

[0010] Therefore, the present invention has been made in view of the above circumstances, and its object is to prevent a shadow from being formed on a part of the body of a lighting object located above the stage or under the lighting by the lighting emitted from a lighting device attached to the ceiling to the lighting object, improve the image of the lighting object, and provide a lighting device for a table that can improve the quality of video content.

Means for Solving the Problems

[0011] In order to achieve the object of the present invention described above, in one embodiment of the present invention, there is provided a table lighting device including a housing having an illumination transmission surface formed so that illumination can pass through, an illumination unit installed inside the housing for irradiating illumination toward the circumference of the neck of an illumination object to remove shadows, a power supply unit installed in the housing for receiving a lighting signal of the illumination unit and lighting the illumination unit, a brightness adjustment unit installed in the housing for receiving a brightness adjustment signal of the illumination unit and adjusting the intensity of the illumination of the illumination unit, and an adapter unit installed in the housing for coupling the housing to a table.

Effects of the Invention

[0012] When the present invention illuminates light toward a table, it can restrictively irradiate illumination around the neck, which is below the eyes of the illumination object, from the table, which is a position lower than the visual field of the illumination object, so that it is possible to prevent glare of the illumination object due to illumination and prevent the formation of shadows around the neck by an illumination device attached to the ceiling.

[0013] In addition, since the present invention forms a uniform illumination brightness on the body of the illumination object, it is possible to improve the image of the illumination object and improve the quality of video content.

[0014] Furthermore, when the present invention is manufactured in a separable type, it can be easily detached from the table. Therefore, when not shooting a video, it can be detached from the table and safely stored, and can be applied to various tables and used.

[0018] Referring to FIGS. 3 to 5, the table lighting device 100 according to the present invention is attached to a table, which is a prop for photography, and irradiates illumination around the neck of an illumination object such as a speaker or a solo media creator. The table lighting device 100 includes a housing 110 having an illumination transmission surface formed thereon, an illumination unit 120 that irradiates illumination from inside the housing 110, a power supply unit 130 that is exposed outside the housing 110 and controls the lighting of the illumination unit 120 according to a lighting signal of the illumination unit, a brightness adjustment unit 140 that is exposed outside the housing 110 and controls the intensity of the illumination of the illumination unit 120 according to a brightness adjustment signal of the illumination unit, and an adapter unit 150 that couples the housing 110 to a table, which is a prop for photography.

[0019] Even if such a table lighting device 100 blocks the illumination irradiated from an illumination device in which a table is installed on a floor surface using the table as a prop for photography, as shown in FIGS. 6 and 7, the table lighting device 100 can irradiate illumination around the neck of the illumination object from the table, and thus provides an effect of not forming a shadow S around the neck of the illumination object.

[0020] Hereinafter, with reference to the drawings, each component will be described more specifically.

[0021] FIG. 8 is a perspective view showing a table lighting device according to a second embodiment of the present invention, FIG. 9 is a perspective view showing a table on which the table lighting device of FIG. 8 is installed, and FIG. 10 is a plan view showing a table lighting device according to a third embodiment of the present invention.

[0022] Referring to FIGS. 3 to 5, the table lighting device 100 according to the present invention includes a housing 110.

[0023] The housing 110 provides a space in which the detailed configuration of the table lighting device 100 is settled and provides the outer shape of the table lighting device 100, and an illumination transmission surface 112 is formed so that illumination can be transmitted therethrough.

[0024] As shown in FIGS. 3 and 4, such a housing 110 can be formed to have a rectangular parallelepiped block structure, and as shown in FIGS. 8 and 9, it can also be formed to have a cylindrical structure, or as shown in FIG. 10, it can be formed on a pair of sheets that are in close contact with each other.

[0025] The housing 110 formed to have the rectangular parallelepiped block structure can have its upper surface formed as the illumination transmission surface 112. At this time, the housing 110 can be formed with an illumination shielding surface composed of metal or synthetic resin on other surfaces except the upper surface. And an illumination reflection sheet for reflecting the illumination irradiated from the illumination unit 120 can be provided on the inner surface of the remaining surfaces except the illumination transmission surface.

[0026] If necessary, the housing 110 having the rectangular parallelepiped block structure can be formed with illumination seating grooves divided into a plurality of horizontal rows as shown in FIG. 5 so that brighter illumination is irradiated to the shadow concentration formation region. Specifically, the housing 110 can be provided with three or more rows of illumination seating grooves having a "U" - shaped cross - section inside, and the first row of illumination seating grooves can be formed to have a smaller inner area than the second row of illumination seating grooves, and the second row of illumination seating grooves can be formed to have a smaller inner area than the third row of illumination seating grooves.

[0027] The housing 110 formed to have the cylindrical structure can be composed of a housing 110 main body having a rod - like structure, a first assembly socket coupled to the left side surface of the housing 110 main body, and a second assembly socket coupled to the right side surface of the housing 110 main body.

[0028] The main body of the housing 110 can have a light-transmitting surface formed thereon as a whole, and the first and second assembly sockets can have a light-blocking surface formed thereon as a whole, which is made of metal or synthetic resin. At this time, a light-reflecting sheet for reflecting the light irradiated from the lighting unit 120 can be provided on the inner surface of the first and second assembly sockets. And the first and second assembly sockets can be formed to have a cup structure with an open side facing the main body of the housing 110 so that the main body of the housing 110 can be inserted and attached thereto.

[0029] The housing 110 formed on the pair of sheets can be composed of a first sheet and a second sheet attached to the upper surface of the first sheet. At this time, the first sheet can be made of a synthetic resin with warping properties, and a light-blocking surface can be formed thereon as a whole. The second sheet can be made of a synthetic resin with warping properties so that the lighting unit 120 can be provided between the second sheet and the first sheet, and a light-transmitting surface can be formed thereon as a whole.

[0030] Specifically, the first sheet can be a flexible material without directionality that can be folded, an electrical insulating material that insulates the electricity flowing through the circuit line, and can be composed of fibers that can withstand temperatures exceeding 250°C. Specifically, the first sheet is preferably composed of aromatic polyamide (aramid) fibers, polyamide fibers, novoloid fibers, carbon fibers, fluorine fibers, or a blend thereof. If such a first sheet is not manufactured from fibers that can withstand temperatures exceeding 250°C, when performing a reflow treatment of heating at a temperature of 150 to 250°C and then cooling so that the conductive adhesive in contact with the lighting unit 120 hardens, problems such as carbonization or shrinkage of the main sheet may occur.

[0031] The second sheet is adhered to the upper surface of the first sheet to protect the lighting unit 120 mounted on the first sheet and the circuit lines provided on the first sheet, and is formed of a sheet through which the light emitted from the lighting unit 120 can pass. Such a front sheet can be composed of synthetic fibers such as polyvinyl chloride (PVC), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), polypropylene (PP), polyethylene (PE), high-density polyethylene (HDPE), low-density polyethylene (LDPE), or linear low-density polyethylene (LLDPE) so as to be folded together with the first sheet by an external force. Also, the second sheet can prevent a short circuit from occurring due to the movement of the circuit lines even when an external impact is applied in order to limit the movement of the circuit lines and the lighting unit 120.

[0032] Optionally, the second sheet can be composed of a diffusion sheet that softens and diffuses the light emitted from the lighting unit 120 and irradiates the lighting target object. Also, the second sheet can be formed to have the same size as the first sheet so as to cover the front surface of the first sheet.

[0033] Referring to FIG. 5, the table lighting device 100 according to the present invention includes a lighting unit 120.

[0034] The lighting unit 120 is installed inside the housing 110 and generates light with the electrical energy supplied from the outside, and serves to irradiate the lighting target object in order to remove the shadow so that no shadow is formed around the neck of the lighting target object.

[0037] If necessary, a number of printed circuit boards are arranged inside the housing 110 so as to be spaced apart from each other on the same line, and are electrically connected to each other via wires or the like. Here, the printed circuit boards are arranged so as to be spaced apart from each other on the same line in order to allow the printed circuit boards to be folded together by an external force. That is, instead of configuring the printed circuit boards on which a number of LED modules are mounted as an integral type, a number of printed circuit boards are electrically connected in a state where they are arranged at positions spaced apart from each other, which is for folding and transporting the lighting device when transporting it.

[0038] On the other hand, the LED module can be composed of a single LED such as a red LED, a green LED, a blue LED, etc., or an RGB LED so that the color temperature can be adjusted.
