Description

Technical Field

[0001] The utility model relates to a lighting device, in particular to a detachable wireless charging spherical lamp. Background Art

[0002] Existing LED or energy-saving spherical light bulbs are generally integrated structures and directly connected to the indoor power supply. However, in the case of a power outage, the light bulb cannot provide lighting, which will cause inconvenience to the user if an emergency occurs.

[0003] In order to solve this problem, many emergency lighting solutions with battery functions have emerged later, such as the prior art CN217875642U. This technical solution is to design an LED lamp with a lamp head that meets national standards and can be directly connected to a solar power source, while also having a built-in battery. When the solar power is cut off, the lighting device can use its own battery to continuously power the LED, thereby achieving indoor lighting.

[0004] The advantage of this technology is that the built-in battery can continuously supply power and provide lighting in the event of power shortage, which is convenient for indoor personnel to use. However, the disadvantage is that the LED lighting device is fixed to a certain place indoors by the lamp head. If the lighting device needs to be moved, the threaded lamp head can only be disassembled, which is more complicated to use and can only be continuously charged by solar energy.

[0005] Therefore, a light that is easier to disassemble and can continue to provide lighting in the event of a power outage is needed to solve this problem. Summary of the invention

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] The purpose of the utility model is achieved by the following methods:

[0031] A detachable wireless charging spherical lamp, the product is mainly composed of two parts, the upper end is a lamp holder 1, and the lower end is a lamp body 2. The lamp holder 1 adopts a national standard interface, such as: E17, E17, E26, B27 and other threaded or socket specifications. It is used to be directly connected to the indoor lamp holder for installation to power the entire bulb. The lamp body 2 is the lighting part composed of an LED light-emitting body 208. The lamp holder 1 and the lamp body 2 are combined by magnetic attraction, and the contact surface of the two is provided with a magnetic attraction structure. When the lamp body 2 is held by hand, the lamp body 2 will be separated from the lamp holder 1. The lamp holder 1 is still connected to the lamp holder, and the lamp body 2 can be separated and emit light separately. The best connection method between the lamp holder 1 and the lamp body 2 is magnetic attraction, and they can also be connected in a snap-fit ​​or tight-fitting manner.

[0032] The lamp holder 1 is composed of a conductive threaded head 101 and an upper shell 102. The upper shell 102 is in a trumpet shape. The small opening at the upper end is fixedly connected to the conductive threaded head 101 by snapping. The lower end is open to form a receiving cavity. A bottom shell 104 is provided at the opening at the lower end to seal the opening at the lower end. Three support columns 204 are provided on the side of the bottom shell 104 facing the receiving cavity. The power conversion board 103 is fixedly mounted on the support columns 204 and fixed to the inner side of the bottom shell 104 with screws. The power conversion board 103 is used to connect to the mains and convert the high-voltage 220V / 110V power supply into 5V or 12V low-voltage electricity to provide power to the LED light-emitting body 208. The technical solution for converting high-voltage electricity into low-voltage electricity is an existing mature technology and is widely used in LED lamps and energy-saving lamps. Its working principle will not be further explained here.

[0033] The bottom shell 104 is a circular sheet structure. Four clamping blocks 1021 are provided at the opening edge of the lower end of the upper shell 102. Correspondingly, four clamping slots are provided on the bottom shell 104. By applying pressure to the bottom shell 104, it can be clamped together with the upper shell 102. At the same time, in order to limit the position of the bottom shell 104, a limiting strip 1022 is provided at the upper end of the clamping block 1021. The bottom end of the limiting strip 1022 is a flat structure, which is used to resist the upper surface of the bottom shell 104. The distance between the limiting strip 1022 and the clamping block 1021 is the thickness of the bottom shell 104. When the bottom shell 104 is clamped, it will be firmly connected with the upper shell 102.

[0034] On the inner side of the bottom shell 104, concentric with the center of the bottom shell 104, there is also an annular groove 1041, and in the annular groove 1041, there is an annular iron sheet 5 (it can also be other materials that can be adsorbed by magnets, such as magnets, cobalt alloys, nickel alloys, etc.). The advantage of using an annular structure is that there is no need to identify the direction. When the lower part of the lamp head 1 and the upper part of the lamp body 2 are close, an adsorption effect can be formed without confirming the direction (if point-shaped magnet adsorption is used, point-to-point adsorption is required). Correspondingly, an annular magnet 4 is provided at the upper end of the lamp body 2. The magnet 4 and the iron sheet 5 have the same size and shape, so as to achieve the best adsorption effect.

[0035] Embodiment 1: Three guide holes 106 are provided at the center of the bottom shell 104, arranged side by side in the diameter direction, the middle guide hole 106 is the center position of the bottom shell 104, and the two guide holes 106 are symmetrically arranged. Correspondingly, three elastic conductive needles 105 are provided at the corresponding positions of the power conversion board 103. The technical scheme of the elastic conductive needle 105 can refer to the existing patents CN220914612U and CN208820098U. The fixed end of the elastic conductive needle 105 is welded on the power conversion board 103 and electrically connected to the output low voltage. The telescopic end of the elastic conductive needle 105 passes through the guide hole 106, and the head is exposed at the lower end of the bottom shell 104. Among them, the conductive needle 105 located at the center of the bottom shell 104 outputs a positive power supply, and the left and right sides output a negative power supply.

[0036] The lamp body 2 includes a spherical lamp shell 201 and a mounting shell 203, both of which are circular and fixedly connected. The mounting shell 203 is in the shape of an annular concave cavity with an opening at the lower end, a mounting surface 2033 at the upper end, and an opening at the lower end. The spherical lamp shell 201 is snapped into the lower opening. The spherical lamp shell 201 is made of transparent PS or PC plastic material for light transmission. The spherical lamp shell 201 and the mounting shell 203 are also connected by snap-fitting. Inside the mounting shell 203, a circular lamp board 206 is provided just above the spherical lamp shell 201, which is fixed to the inside of the mounting shell 203 through a support column 204. The support column 204 and the mounting shell 203 are connected, and the lamp board 206 is fixed to the support column 204 with screws. The lower surface of the lamp board 206 is provided with an LED light-emitting body 208, which faces the transparent spherical lamp shell 201. A control circuit chip is provided on the upper surface of the lamp board 206 for controlling the LED light source 208 and controlling the charging of the rechargeable battery 3, and the lamp board 206 and the conductive plate 207 are connected by a wire for introducing the energy converted from the mains into the low-voltage power supply into the lamp board 206.

[0037] A concave annular groove 1041 is provided on the outside of the mounting surface 2033 of the mounting shell 203, and an annular magnet 4 is provided in the annular groove 1041. The conductive plate 207 and the annular magnet 4 are arranged concentrically, and the annular magnet 4 corresponds to the annular iron sheet 5. A conductive through hole 2034 is also provided at the center of the mounting surface 2033, so that the exposed part of the lower end of the conductive needle 105 can pass through the conductive through hole 2034. The conductive plate 207 is arranged directly below the conductive through hole 2034, and the conductive plate 207 and the conductive needle 105 are in contact. The center of the conductive plate 207 is a dot-shaped positive contact copper foil 2072, which is electrically connected to the positive conductive needle, and the periphery of the positive contact copper foil 2072 is an annular negative contact copper foil 2071, which is electrically connected to the two negative conductive needles. The advantages of the conductive plate 207 using this design are: with the annular magnet 4, it can achieve conductive connection at any angle in the circumferential direction, which is convenient for users to disassemble and then install without direction identification.

[0038] The upper surface of the lamp board 206 is provided with a control circuit module for controlling the LED light emitting body 208 and charging the battery 3, and the rechargeable battery 3 is arranged above the lamp board 206. The control circuit module is an existing technical solution and has been widely used in products such as LED desk lamps, and will not be described in detail here.

[0039] For the convenience of use, a handle 205 is provided at the top edge of the mounting shell 203, and the handle 205 is rotatably connected to the mounting shell 203. A groove 202 is provided at the edge of the mounting shell 203 for accommodating the handle 205. When the user removes the lamp body 2, the handle 205 can be hung on any hook for easy use. At the same time, the adsorption capacity of the magnet 4 can also be used to adsorb the lamp body 2 on magnetic materials, such as refrigerator doors, iron doors, etc.

[0040] A push button switch 2032 is also provided on the edge of the mounting shell 203 . The push button switch 2032 is electrically connected to the light board 206 and is used to manually control the on / off state of the LED light source 208 .

[0041] When in use, the spherical lamp is first connected to the lamp holder of the mains. When in normal use at night, the mains provides energy to the bulb and can also charge the battery 3 to ensure that the rechargeable battery 3 has sufficient power. When a power outage occurs, the rechargeable battery 3 can provide emergency energy to achieve lighting.

[0042] If mobile lighting is required, the lamp body 2 of the bulb can be removed and used as a flashlight. The lamp body 2 can also be placed in other fixed positions to provide lighting by using the magnetic attraction and the handle 205 .

[0043] When the lamp is used, the lamp body 2 is adsorbed under the lamp holder 1, and the lamp can continue to be illuminated and charged using the mains electricity.

[0044] Example 2, based on the technology of Example 1, the elastic conductive needle 105 is replaced with a wireless charging module transmitter module, which is set at the bottom center of the power conversion board 103, and the wireless charging module receiver module is set at the corresponding position of the conductive plate 207. This type of wireless charging module has been widely used in various mobile phone charging occasions and is an existing technical solution. This technical solution is simpler and more convenient. However, its cost is relatively high.

[0045] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as the protection scope of the present invention.
