Lighting for desk furniture that can rotate and adjust angle}

The present invention relates to lighting that is mounted on various desk furniture. More specifically, it is mounted on the bottom of the storage compartment of desk furniture to illuminate the table top at a desired position and angle, or when the desk furniture has a swing-type table, the table top is illuminated at a desired position and angle. The present invention relates to a lighting lamp for desk furniture in which the lighting is pulled out and rotated from the bottom of the storage compartment according to the swing position of the table to produce lighting with the optimal shape in the position and direction desired by the user.

In general, desk furniture is very widely used for work or study. It ranges from a desk with a simple structure consisting of only a top plate and lower support angles to a storage unit integrated with the top on the front of the table or an independent storage unit in the form of a combined top plate. There are many different sizes and designs, including desk furniture with storage compartments.

In particular, in the case of desk furniture with a storage compartment, the storage compartment formed at a higher position than the table may interfere with the irradiation angle of the ceiling lighting, which may reduce the illumination of the upper surface of the table. Therefore, if necessary, a separately provided stand light may be used, and the bottom of the storage compartment may be used. In desk furniture that secures a certain amount of space, straight or bar-type lights are installed on the bottom of the storage compartment to directly illuminate the upper surface of the table (or top).

In this way, in desk furniture, the upper surface of the table is shaded or dark spots are created due to the storage part or the user blocking the irradiation angle of the ceiling light, so it is essential to use a separate stand light or furniture-integrated lighting. This could be said to be general.

At this time, in the case of lighting directly mounted on furniture as described above, it consists of an installation box, clamp, length adjustment rod, and rotating plate as in Registered Utility Model No. 20-0221675, and the installation box is designed to be attached to the ceiling or wall. The clamp is connected to the installation box and rotates 360° and is designed to fix the length adjustment rod. The length adjustment rod is inserted into the clamp and moves left and right to adjust the distance from the installation box to the light bulb. The rotating plate is A lighting device that is connected to one end of a length-adjusting rod and can rotate 360° with the length-adjusting rod, allowing the position to be adjusted by rotating the bulbs when installing two or more light bulbs, has been developed and registered.

Next, in the case of Registered Utility Model No. 20-0356255, there is a fluorescent light cover formed to accommodate the fluorescent light and be able to rotate through a rotating hinge, a fluorescent light that is stored in this fluorescent light cover and rotates, a socket, a fluorescent light cover, and a fluorescent light that rotates. a lighting unit having a left rotation support unit and a right rotation support unit installed on the opposite side of the rotation support unit; a left support portion that is rotatably located on the left side of the lighting unit, and is equipped with a support body and a pivot hinge that combines with the left pivot support portion to rotate the fluorescent lamp; A power supply body equipped with a pivoting hinge on one side that combines with the right pivoting support portion to rotate the fluorescent lamp, a switch for turning the fluorescent lamp on and off, an illumination control unit for controlling the illuminance of the fluorescent lamp, an earphone holder, and a separate power supply. A desk lighting device consisting of a right support unit equipped with an outlet that supplies light has been developed and registered.

In addition, as in Registered Patent No. 10-0805746, a main body including left and right partitions spaced a certain distance apart, a storage room provided in the upper part of the left and right partitions, and a reading board provided in the center of the left and right partitions; A lighting means comprising a PCB, a plurality of LEDs mounted on one side of the PCB, and a heat sink attached to one side so that the other side of the PCB is in close contact with the other side of the PCB, and disposed in a lower part of the storage compartment of the main body to illuminate the reading board; A desk for a reading room including a control unit that is electrically connected to the lighting unit and controls the lighting unit has been developed and registered.

Next, in the case of Patent No. 10-1435850, base; A panel having a front and back surface provided with a light emitting unit; A first rotating member provided at one end of the base; a second rotating member provided at the other end of the panel; And it includes a connecting member connecting the first rotating member and the second rotating member, wherein the first rotating member forms the rotation center of the other end of the panel and the second rotating member forms the rotation center of one end of the panel. A lighting device featuring this feature has been designed and registered.

In addition, in the case of Registered Patent No. 10-1836885, it is a lighting device installed on the lower shelf of a locker placed on the upper part of a desk in a reading room to supply lighting, and includes a lighting fixture; And connected to the lighting fixture to control the emission of light of the lighting fixture, and controlled to emit repeatedly for a first time at a preset first level to a fifth level by the learner's selection or at each preset first cycle. A lighting device for a reading room desk that includes a lighting control panel has been designed and registered.

However, most of the lighting lamps for desk furniture as described above are fixedly installed inside the storage unit and only have a predetermined angle adjustment for the lighting direction, which causes the problem of not being able to produce lighting in various positions and directions desired by the user. Lighting from various directions or positions may be necessary depending on the user's taste, posture, or type of study or work, but lighting fixed to the bottom of the storage compartment is the best because it is extremely limited in terms of changing the position or adjusting the angle. It is not possible to implement lighting in the form of .

In particular, in recent years, swing table desk furniture with a rotating table has become widely used. The table is positioned perpendicular to the storage unit on the plane, or the table is pulled out and rotated at a right angle from the storage unit on the plane. Possibly, this allows desk furniture to be used more efficiently by changing the table's usage position. In this way, desk furniture with a swinging table can be used to control the top of the table in a rotating state using the lighting mounted on the bottom of the storage section. Since it cannot illuminate at all, it has the disadvantage of having to purchase and use a separate stand light.

However, drawing out and refracting types of lighting have been proposed in the past, but they have the disadvantage of being very large and heavy as they have a very complex structure and are made up of overlapping frames. They do not have a strong interlocking force, so they sag at the ends of the lighting. It is true that there are structural vulnerabilities, such as failure to maintain a stable installation condition.

Next, the lighting unit 300 described above is installed inside the lighting body 310 extruded in a downwardly opened state as shown in FIG. 9 and includes an LED light source plate 320 and a light transmitting plate along the longitudinal direction of the lighting body 310. It is constructed by slidingly inserting (330), and on the inside of the lower end of the lighting body 310, coupling grooves 311 (311') are formed into which both ends of the light transmitting plate 330 are inserted, thereby forming an LED light source plate ( The lighting light of 320 is configured to diffuse downward through the light transmitting plate 330 located on the lower side, and in the case of the LED light source plate 320, a sliding insertion groove (not shown in the drawing) is additionally formed to allow sliding insertion or It may be possible to bolt it in close contact with the inner end of the lighting body 310 using a separate fastening bolt.

As a result, an external wire is guided to be inserted through the wire entry groove 111 in the fixing body 110 of the mounting unit 100, and at the same time, the LED light source of the lighting unit 300 is transmitted via the control unit 220 of the operating unit 200. As the wiring is made to make an electrical connection to the plate 320, the operation unit 223 of the control unit 220 can be used to turn on or off the lighting unit 300, adjust the brightness of the lighting, or control the lighting duration or lighting time. Reservation settings will be possible.

Next, the end of the lighting body 310 constituting the lighting unit 300 is formed by combining a separately provided finishing device 350, and as shown in FIG. 10, there is a longitudinal section on the inside of the lighting body 310. The fastening bolt 360 is coupled to the bolt fastening grooves 312 (312') formed along the bolt fastening grooves 312 and 312', penetrating the finishing hole 350 from the outside of the finishing hole 350. The finishing device 350 is configured to be firmly fixed to the end of the lighting body 310 by (360').

In addition, a fastening protrusion 351 is formed at one end of the closure 350 to be inserted into the inside of the lighting body 310, so that the fastening protrusion 351 is inserted into the end of the lighting body 310 first. After the fastening protrusion 351 is used to guide the assembly of the finishing tool 350 to the lighting body 310, the fastening bolts 360 and 360' are used to securely and tightly fix the lighting body 310. These fastening protrusions 351 will also serve to prevent the closure 350 from moving or opening from the lighting body 310.

In particular, a separately provided magnet body 370 is inserted and fixed inside the above-described closing device 350, and a separately provided metal pad 380 is provided on the upper side of the closing device 350 to form an upper storage compartment 400. As the metal pad 380 attached to the bottom of the and the magnet body 370 in the finishing hole 350 are attached to each other by attraction, the lighting unit 300 is rotated and connected in a deflected state from the mounting unit 100 through the operating unit 200. ) may be configured to prevent deflection or flow.

Here, in the case of the metal pad 380, it can be formed by forming a double-sided tape with release paper on the upper surface and attaching a noise-prevention pad made of non-woven fabric, etc. to the bottom surface. The metal pad 380 is attached to the upper storage compartment 400. When the top of the finish 350 coupled to the end of the lighting body 310 of the lighting unit 300 is rotated so that the upper side is positioned on the bottom of the metal pad 380 while previously attached and fixed to the bottom of the lighting unit 300, the metal pad 380 Due to the attractive force of the magnet body 370 in the finishing device 350, the closing device 350 will remain attached to the bottom of the metal pad 380, so ultimately, the fixed installation structure at the other end of the lighting unit 300 The sagging phenomenon at the end of the lighting unit 300 due to the deflection characteristics of the lighting lamp can be prevented very simply and effectively.

Next, the rotation coupling structure between the rotation coupling end 120 of the fixing body 110 of the mounting unit 100 and the first rotation connector 230 of the operation main body 210 of the operating unit 200 is flat as shown in FIG. 11.

(230) It is designed so that the mutual rotation between them occurs smoothly.

Therefore, when the fixing bolts 250 and 250' are tightened so that the tight fixture 260 has a downward pressing force, the first rotary connector 230 between the rotary coupling end 120 and the tight fixture 260 is rotated. There is a pressing force in a state in which the end portion 120 and the close contact fixture 260 are mutually grounded, and due to the pressing force in this close contact state, the operating part 200 does not rotate arbitrarily from the mounting part 100, but artificial force This will produce a combined structure that operates in mutual rotation.

In addition, the lower slip pad 271 serves to reduce wear or noise between the rotary coupling end 120 and the first rotary connector 230 and at the same time serves to increase mutual friction due to a certain cushioning effect. , the upper slip pad 272 serves to reduce wear or noise between the first rotation connector 230 and the close fitting fixture 260, and at the same time performs a certain cushioning action to enable a smoother and quieter rotation. .

In particular, a first resting ledge 231 on which the close fitting fixture 260 and the upper slip pad 272 are placed is formed on the upper part of the above-mentioned first rotation connector 230, and the upper part of the first resting ledge 231 is formed. A second resting ledge 232 having an expanded inner diameter than the first resting ledge 231 is formed so that a separately provided circular cover 280 is placed in a non-contact state with the close fitting fixture 260. It can also be configured to be pressurized and fastened within, and the circular cover 280 will rotate together with the first rotary connector 230 while maintaining the coupled state to the first rotary connector 230, so that it will eventually be connected to the close fixture 260 from the outside. ) will be concealed to create a simple and beautiful exterior, and will also serve to prevent foreign substances or dust from penetrating between the close fitting fixture 260 and the first rotating connector 230.

This mutual rotation coupling structure between the mounting unit 100 and the operating unit 200 is equally applied to the mutual rotation coupling structure between the operating unit 200 and the lighting unit 300, and as shown in FIG. 12, the operating unit 200 ) The rotational coupling structure between the second rotary connector 240 of the operating body 210 and the rotary coupling port 340 of the lighting body 310 of the lighting unit 300 is formed on the rotary coupling port 340, which is circular in plan. The second rotary connector 240, which has a circular ring shape in plan, is mounted and separately provided fixing bolts 250 (250') inserted from the bottom of the rotary coupler 340 are used for the second rotary connector 240. It is configured to be screwed and fixed to the bottom of a separately provided close fixture 260 placed from the top.

In addition, a separately provided lower slip pad 271 is inserted between the upper surface of the above-mentioned rotary coupler 340 and the bottom surface of the second rotary connector 240, and a fastener in close contact with the upper surface of the second rotary connector 240. An upper slip pad 272 is inserted between (260), and the mutual rotation action between the rotary coupler 340 and the second rotary connector 240 is performed by these lower and upper slip pads 271 and 272.
