Description

Background of the inventionTechnical field

[0001] The present invention relates to a lighting device, in particular a wireless charging lamp in a spherical shape that can be used detachably. State of the art

[0002] Currently available LED or energy-saving spherical bulbs typically have a one-piece structure and are directly connected to the power grid. However, in the event of a power outage, these bulbs cannot provide illumination, which can be inconvenient for the user in emergencies.

[0003] To solve this problem, many emergency lighting solutions were later developed that feature a built-in battery and can be connected to both solar panels and the mains. In the event of a power outage, these lighting devices can use the built-in batteries to continue powering the LEDs, thus providing emergency lighting indoors.

[0004] The advantage of this solution is that the built-in battery continues to supply power and provide illumination in the event of a power outage, benefiting those inside. The disadvantage, however, is that this LED lighting device is installed in a fixed indoor location and does not provide mobile lighting.

[0005] Therefore, there is a need for a more easily removable device that continues to provide lighting even during a power failure to solve this problem. Disclosure of the invention

[0006] The aim of the present invention is to remedy the above-mentioned deficiencies and to provide a detachable, wireless charging lamp in spherical shape, which enables charging through the detachable connection between the lamp head and the lamp body and at the same time offers the possibility of using the lamp body separately for mobile lighting.

[0007] The object of the present invention is achieved by the following features:

[0008] A detachable, wireless charging spherical light consisting of a lamp head and a lamp body. The lamp body is located below the lamp head and serves as a lighting fixture. A detachable connection exists between the lamp head and the lamp body. Inside the lamp head is a power conversion board that receives electrical current from the mains and converts it into low-voltage current. Inside the lamp body is a circuit board that conducts the low-voltage current from the power conversion board into the lamp head to charge the battery in the lamp body and simultaneously power the LEDs in the lamp body. The battery allows for continuous power supply to the LEDs even when the lamp head and lamp body are completely separated.At least two elastic current-conducting pins are attached to the bottom of the power conversion board, which correspond to at least two concentric ring-shaped conductive copper foils on the circuit board. The spacing between the conductive copper foils corresponds to the spacing between the elastic current-conducting pins. When the lamp body and the lamp head are connected, an electrical connection is established between the elastic current-conducting pins and the conductive copper foils. This design allows the lamp head and the lamp body to be separated from each other while simultaneously installing a battery in the lamp head. This allows the battery to be charged when the mains power is connected, and in the event of a power failure, the built-in battery provides continuous lighting. Furthermore, the lamp body can be easily removed and used as an indoor emergency light.The uniform arrangement of the ring-shaped conductive copper foils allows electrical connection at any angle, making installation safer and more user-friendly.

[0009] In the above description, in a preferred embodiment, the circuit board is attached to the upper part of the lamp body, and the upper part of the lamp body is provided with a conductive through-hole through which the conductive copper foil is exposed to facilitate contact between the elastic current conducting pins and the conductive copper foil.

[0010] One technical concept is that the number of elastic current-conducting pins is two, arranged in parallel, one connected to the positive pole and the other to the negative pole of the power supply. The center of the conductive copper foil is a point in contact with the elastic current-conducting pin of the positive pole, and its surroundings are surrounded by a concentric ring-shaped copper foil in contact with the elastic current-conducting pin of the negative pole.

[0011] Another technical concept involves three elastic current-conducting pins arranged in parallel, with the middle elastic current-conducting pin connected to the positive pole and the two outer elastic current-conducting pins connected to the negative pole of the power supply. The center of the conductive copper foil is a point in contact with the elastic current-conducting pin of the positive pole, and its surroundings are surrounded by a concentric ring-shaped copper foil in contact with the elastic current-conducting pin of the negative pole.

[0012] Another technical solution involves two elastic current-conducting pins arranged in parallel, one connected to the positive pole and the other to the negative pole of the power supply. The conductive copper foil consists of two concentric annular copper foils, with the inner ring in contact with the elastic current-conducting pin of the positive pole and the outer annular copper foil in contact with the elastic current-conducting pin of the negative pole.

[0013] Another technical concept involves three elastic current-conducting pins arranged in parallel, with the middle elastic current-conducting pin connected to the positive pole and the two outer elastic current-conducting pins connected to the negative pole of the power supply. The conductive copper foil consists of two concentric ring-shaped copper foils, with the inner ring in contact with the elastic current-conducting pin of the positive pole and the outer ring-shaped copper foil in contact with the elastic current-conducting pin of the negative pole.

[0014] In the above description, in a preferred embodiment, the lamp head is composed of a conductive screw head and an upper housing, which are connected to each other by snapping. The upper housing is shaped like a funnel with an opening at the lower end, which forms a receiving chamber in which the power conversion board is housed. At the open end of the upper housing is a bottom shell, which serves to encapsulate the power conversion board. In the center of the bottom of the power conversion board are at least two elastic current conducting pins, which are guided through corresponding guide holes in the center of the bottom shell, so that the tips of the current conducting pins are exposed on the underside of the bottom shell.

[0015] In a preferred embodiment, the upper surface of the bottom shell is provided with an annular recess in which an annular iron piece is arranged.

[0016] The lamp body consists of a spherical lamp housing and a mounting shaft, which are firmly connected to each other. The mounting shaft is a downwardly open recess with a mounting surface at its upper end. The circuit board is firmly attached to the center of the mounting surface. In the center of the mounting surface is a conductive through-hole. On the outside of the mounting surface is an annular recess in which a ring-shaped magnet is arranged. Also inside the mounting shaft are a support and a lamp plate. The support is connected to the mounting shaft, and the lamp plate is fastened to the support with screws. LED bulbs are mounted on the underside of the lamp plate, and the lamp plate is connected to the battery and the circuit board via wires.

[0017] In a preferred embodiment, a control board is mounted on the top of the lamp plate, which serves to control the LED lamps and to charge the battery.

[0018] In a preferred embodiment, a handle is attached to the upper edge of the mounting shaft, which is pivotally connected to the mounting shaft. A groove is provided on the edge of the mounting shaft to accommodate the handle. A push-button switch is also attached to the edge of the mounting shaft, which serves to manually control the switching on and off of the LED lamps.

[0019] The beneficial effect of this invention is that the mains current is continuously used to power the spherical lamp's integrated battery, which is reliable and stable. At the same time, the simple, detachable design of the lamp body solves the technical deficiencies of existing designs, facilitates disassembly, and enables mobile lighting. The uniform arrangement of the annular conductive copper foils allows for electrical connection at any angle, making installation safer and more user-friendly.

[0021] In the following, the present invention will be described in more detail with reference to the accompanying drawings and specific embodiments.

[0022] The present invention is realized by the following features:

[0023] Example 1: A removable, wireless charging light in a spherical shape. Regarding the Fig. This product mainly consists of two main parts: the upper part, the lamp head 1, and the lower part, the lamp body 2. The lamp head 1 uses standard connectors such as E17, E26, B27, and other threaded or socket specifications to directly connect to an indoor lamp socket and power the entire light fixture. The lamp body 2 consists of the LED light source 208, which provides lighting. The lamp head 1 and the lamp body 2 are coupled by a magnetic connection; the contact surfaces of both parts are equipped with a magnetic structure. When the lamp body 2 is pulled downward, the lamp body 2 separates from the lamp head 1. The lamp head 1 remains connected to the lamp socket, while the lamp body 2 can illuminate independently. The preferred connection between the lamp head 1 and the lamp body 2 is magnetic, but a snap-in or fit-in connection is also possible.

[0024] Regarding the Fig. The lamp head 1 consists of a conductive screw head 101 and an upper housing 102. The upper housing 102 is shaped like a funnel, with the smaller upper end firmly locked to the conductive screw head 101. The lower end is open and forms a receiving chamber. A bottom cover 104 is located at the lower opening, closing the opening. On the side of the bottom cover 104 facing the receiving chamber, there are three support columns 204 to which the power conversion board 103 is attached. The power conversion board 103 is designed to be connected to the mains power and convert the 220V / 110V high voltage into 5V or 12V low voltage to power the LED lamp 208. Converting high voltage to low voltage is an established technology widely used in LED lamps and energy-saving lamps; Therefore, the operating principle will not be explained further here.

[0025] Regarding the Fig. The base shell 104 has a disc-shaped structure. At the edge of the lower opening of the upper housing 102 are four locking blocks 1021, which correspond to four corresponding recesses in the base shell 104. By pressing on the base shell 104, it can be firmly locked to the upper housing 102. To determine the position of the base shell 104, there are limiting strips 1022 above the locking blocks 1021, the flat underside of which rests against the top of the base shell 104. The distance between the limiting strips 1022 and the locking blocks 1021 corresponds to the thickness of the base shell 104. Once locked, the base shell 104 is firmly connected to the upper housing 102.

[0026] On the inner surface of the base shell 104, concentric with the center of the base shell, there is an annular slot 1041 in which a ring-shaped iron piece 5 is located (alternatively, other magnetically attractive materials such as magnets, cobalt alloys, nickel alloys, etc. can be used). The advantage of the annular structure is that no directional determination is required; as soon as the lower part of the lamp head 1 and the upper part of the lamp body 2 approach each other, a magnetic attraction occurs without directional determination (with point magnets, point-to-point alignment would be required). At the upper end of the lamp body 2 is an annular magnet 4, the size and shape of which correspond to the iron piece 5 to ensure optimal magnetic attraction.

[0027] Regarding the Fig. In the center of the base shell 104, there are three guide holes 106 arranged in a line along the diameter. The middle guide hole 106 is located exactly in the center of the base shell 104, while the other two are arranged symmetrically to it. At the corresponding locations on the power conversion board 103 are three elastic current conducting pins 105, the technology of which is described in patents CN220914612U and CN208820098U. The fixed ends of the elastic current conducting pins 105 are soldered to the power conversion board 103 and electrically connected to the low-voltage output. The movable ends of the elastic current conducting pins 105 penetrate the guide holes 106, with the tips visible on the underside of the base shell 104. The centrally positioned current conducting pin 105 provides the positive pole, while the current conducting pins arranged to the left and right provide the negative pole.

[0028] Regarding the Fig. The lamp body 2 consists of a spherical lamp housing 201 and a mounting shaft 203, both of which are round and firmly connected to one another. The mounting shaft 203 has the shape of a downwardly open annular recess, the upper end of which is provided with a mounting surface 2033. The spherical lamp housing 201 is attached to the lower opening. It is made of transparent PS or PC plastic and serves to transmit light. The spherical lamp housing 201 and the mounting shaft 203 are also connected to one another by snap-in connections. Inside the mounting shaft 203, directly above the spherical lamp housing 201, there is a round lamp plate 206, which is firmly connected to the mounting shaft 203 by support columns 204. The lamp plate 206 is fastened to the support columns 204 with screws.On the underside of the lamp plate 206 are LED bulbs 208, which are aligned with the transparent spherical lamp housing 201. On the top of the lamp plate 206 is a control chip that controls the LED bulbs 208 and regulates the charging of the battery 3. The lamp plate 206 is connected to the circuit board 207 via wires to conduct the energy converted into low voltage into the lamp plate 206.

[0029] Regarding the Fig. On the outside of the mounting surface 2033 of the mounting shaft 203, an annular slot 1041 is machined, in which an annular magnet 4 is located. The circuit board 207 and the annular magnet 4 are arranged concentrically, with the annular magnet 4 corresponding to the annular iron piece 5. In the center of the mounting surface 2033 is a conductive through-hole 2034 through which the ends of the current-conducting pins 105 protrude. The circuit board 207 is mounted directly below the through-hole 2034 and is in contact with the current-conducting pins 105. The center of the circuit board 207 forms a point-shaped positive copper foil 2072, which is electrically connected to the positive current-conducting pin 1052. The surroundings of the positive copper foil 2072 are provided with an annular negative copper foil 2071, which is electrically connected to the two negative current conducting pins 1051.The advantage of this circuit board design is that, together with the ring-shaped magnet 4, it allows for electrical connection at any angle, ensuring user-friendly installation without requiring any directionality. As shown in . Fig. As can be seen, the consistency of the distance between the copper foils and the current conducting pins ensures that the negative current conducting pins 1051 and the positive current conducting pin 1052 precisely contact the negative copper foil 2071 and the positive copper foil 2072 in every horizontal direction and establish an electrical connection.

[0030] In relation to Fig. The top of the lamp plate 206 is equipped with a control circuit module that serves to control the LED lamps 208 and to charge the battery 3. The battery 3 is arranged above the lamp plate 206. The control circuit module is based on an established technical concept that is already widely used in LED table lamps and similar products; therefore, a detailed description is omitted here.

[0031] Regarding the Fig. For ease of use, a handle 205 is attached to the upper edge of the mounting shaft 203. The handle 205 is pivotally connected to the mounting shaft 203. A groove 202 is provided on the edge of the mounting shaft 203 to accommodate the handle 205. When the user removes the lamp body 2, they can hang it on any hook using the handle 205, making it easier to use. At the same time, the lamp body 2 can also be attached to magnetic surfaces such as refrigerator doors or iron doors thanks to the magnetic attraction of the magnet 4.

[0032] On the edge of the mounting shaft 203 there is also a push-button switch 2032 which is electrically connected to the lamp plate 206 and serves to manually control the switching on and off of the LED lamps 208.

[0033] During use, the spherical lamp is first inserted into a mains-powered lamp socket. During normal nighttime operation, the lamp is powered by the mains power and simultaneously charges battery 3 to ensure that the battery is fully charged. In the event of a power outage, battery 3 can serve as an emergency power source, thus maintaining the lighting.

[0034] When mobile lighting is required, the lamp body 2 can be detached from the lamp head to be used as a flashlight. Furthermore, thanks to the magnetic attraction and the handle 205, the lamp body 2 can be attached to other fixed positions to provide light.

[0035] After use, the lamp body 2 can be reattached under the lamp head 1 to continue receiving light and charging from the mains current.

[0036] Example 2 (see Fig. ): Based on Embodiment 1, two elastic current conducting pins 105 are provided. The center of the corresponding circuit board 207 is point-shaped and forms the positive contact copper foil 2072, which is in contact with the positive current conducting pin 1052. The surrounding annular negative contact copper foil 2071 is in contact with the negative current conducting pin 1051, thus establishing the electrical connection.

[0037] Example 3 (see Fig. ): Based on Embodiment 1, two elastic current-conducting pins 105 are provided. The corresponding circuit board 207 is equipped with two concentric ring-shaped copper foils. The inner ring forms the positive contact copper foil 2072, which is in contact with the positive current-conducting pin 1052. The outer ring forms the negative contact copper foil 2071, which is in contact with the negative current-conducting pin 1051, thereby establishing the electrical connection.

[0038] Example 4 (see Fig. ): Based on Embodiment 1, three elastic current conducting pins 105 are provided. The corresponding circuit board 207 is equipped with three concentric ring-shaped copper foils. The inner ring forms the negative contact copper foil 2071, which is in contact with the inner negative current conducting pin 1051. The middle ring forms the positive contact copper foil 2072, which is in contact with the middle positive current conducting pin 1052. The outer ring forms another negative contact copper foil 2071, which is in contact with the outer negative current conducting pin 1051, thereby establishing the electrical connection.

[0039] From the above mentioned design possibilities it is clear that the lamp body 2 can be connected to the lamp head 1 at any angle, thus ensuring a precise electrical connection (see Fig.), and the current from the lamp head 1 can be directed exactly into the lamp body 2.
