Description

Technical field:

[0001] The present invention relates to the field of lighting technology, and in particular to a dimming device, a lamp and a dimming method. Background technology:

[0002] As a new type of light source, LED has many advantages such as fast response, no flicker, easy integration, long service life, energy saving and environmental protection. It is an inevitable trend for LED to replace incandescent lamps or fluorescent lamps as the light source of lamps.

[0003] With the improvement of living standards, people have higher and higher requirements for desk lamps. The dimming device is the core control of the light source of the lamp. The light is adaptively adjusted through the dimming device to meet the usage requirements in different ambient light and usage scenarios.

[0004] However, current dimming devices generally use touch dimming to achieve graded adjustment through touch. The adjustment process is discontinuous and uneven, and the dimming level is not fine enough, which can easily affect the user experience.

[0005] In view of this, the inventor proposes the following technical solution. Summary of the invention:

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a dimming device, a lamp and a dimming method.

[0007] In order to solve the above technical problems, the present invention adopts the following first technical solution: the dimming device includes a carrier, a touch control board installed in the carrier, a light-transmitting cover fixed to the upper end of the carrier and covering the upper end of the touch control board, and a membrane attached to the upper end of the light-transmitting cover. The touch control board is provided with two groups of first antenna groups and second antenna groups for sensing touch actions, wherein the first antenna group includes a plurality of first antennas distributed in a circular clockwise manner, and the area of the first antenna gradually decreases from one end to the other end. When a touch action is performed clockwise on the upper edge of the first antenna group, The area of the first antenna is from large to small; the second antenna group includes multiple second antennas distributed in a circular counterclockwise manner, and the area of the second antenna gradually increases from one end to the other end. When the second antenna group is touched counterclockwise, the area of the second antenna is from small to large; and the first antenna and the second antenna are staggered and distributed in opposite directions, the end of the second antenna with a small area is located next to the end of the first antenna with a large area, and the end of the second antenna with a large area is located next to the end of the first antenna with a small area, so that when a finger touches the membrane, it is sensed by the first antenna and the second antenna at the same time.

[0008] Furthermore, in the above technical solution, the sides of the adjacent first antenna and second antenna are in contact with each other.

[0009] Furthermore, in the above technical solution, the end with a smaller area of the previous first antenna is located beside the end with a larger area of the next first antenna, and the end with a smaller area of the previous second antenna is located beside the end with a larger area of the next second antenna.

[0010] Furthermore, in the above technical solution, the carrier includes a base and an upper cover sleeved around the outer periphery of the upper end of the base. The middle part of the upper end of the base penetrates through the upper cover. The touch control board, the light-transmitting cover, and the diaphragm are sequentially arranged from bottom to top in the middle of the upper end of the base and are exposed in the upper cover.

[0011] Furthermore, in the above technical solution, a ring groove is formed between the outer periphery of the middle part of the upper end of the base and the inner wall of the upper cover. A handle that can be received and opened outward to protrude above the upper cover is arranged in the ring groove.

[0012] To solve the above technical problems, the present invention adopts the following second technical solution: A lamp, which uses the above dimming device. The lamp includes a lantern-shaped lampshade, a bottom cover installed at the lower end of the lantern-shaped lampshade, a battery installed in the bottom cover, and a multi-angle LED light-emitting module installed at the lower end of the dimming device and extending into the lantern-shaped lampshade from top to bottom. The dimming device is fixed to the upper end of the lantern-shaped lampshade. A main control PCB is arranged in the carrier of the dimming device. The multi-angle LED light-emitting module, the touch control board, and the battery are all electrically connected to the main control PCB.

[0013] Furthermore, in the above technical solution, a plurality of grooves distributed from top to bottom are arranged on the outer periphery of the lantern-shaped lampshade, and decorative reinforcing ribs are arranged in the grooves; the multi-angle LED light-emitting module includes an aluminum rod fixedly connected to the carrier and having a polygonal cross-section, and a plurality of LED lamp boards fixed to the outer side surface of the aluminum rod. The lower end of the aluminum rod is also fixedly connected to the bottom cover.

[0014] Furthermore, in the above technical solution, the lamp is placed on a tray, and a wireless charging module is arranged inside the tray. A coil module adapted to the wireless charging module is also arranged in the bottom cover.

[0015] To solve the above technical problems, the present invention adopts the following third technical solution: The dimming method is as follows: First step: Define the touch action of sliding clockwise as the first action to gradually dim the light of the lamp; Define the touch action of sliding counterclockwise as the second action to gradually brighten the light of the lamp. Second step: Use the first antenna group to sense and collect the first signal of the touch action of sliding clockwise, and at the same time use the first antenna group to sense and collect the second signal of the touch action of sliding counterclockwise, and receive the first signal or the second signal through the main control PCB. When it is judged that the received signal is the first signal, perform the first action to gradually dim the light of the lamp; When it is judged that the received signal is the second signal, perform the second action to gradually brighten the light of the lamp; When the touch action does not stop and changes direction, when the main control PCB judges that the received signal changes from the first signal to the second signal, the control of the lamp can be changed from gradually brightening the light of the lamp to gradually dimming the light of the lamp; Or when the main control PCB judges that the received signal changes from the second signal to the first signal, the control of the lamp can be changed from gradually dimming the light of the lamp to gradually brightening the light of the lamp.

[0016] Furthermore, in the above technical solution, the first antenna group includes a plurality of first antennas sequentially distributed in a clockwise ring shape, and the area of the first antenna gradually becomes smaller from one end to the other end. When a clockwise touch action is performed on the first antenna group, the area of the first antenna becomes smaller from large to small to gradually dim the light of the lamp; The second antenna group includes a plurality of second antennas sequentially distributed in a counterclockwise ring shape, and the area of the second antenna gradually becomes larger from one end to the other end. When a counterclockwise touch action is performed on the second antenna group, the area of the second antenna becomes larger from small to large to gradually brighten the light of the lamp; And the first antenna and the second antenna are staggered and distributed in opposite directions. The end with a small area of the second antenna is located beside the end with a large area of the first antenna, and the end with a large area of the second antenna is located beside the end with a small area of the first antenna, and the sides of adjacent first antennas and second antennas are in contact. When touching the diaphragm, it is sensed by both the first antenna and the second antenna at the same time. When it is judged that the received signal is the first signal or the second signal, the first action or the second action is controlled to gradually dim or brighten the light of the lamp.

[0017] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0018] 1. During the use of the dimming device, the dimming device uses the first antenna group to sense and collect the first signal of the touch action sliding clockwise, and at the same time uses the first antenna group to sense and collect the second signal of the touch action sliding counterclockwise, and receives the first signal or the second signal through the main control PCB. When it is determined that the received signal is the first signal, the first action is performed to control the light of the lamp to gradually dim; when it is determined that the received signal is the second signal, the second action is performed to control the light of the lamp to gradually brighten; since the touch action refers to circular sliding touch in the clockwise or counterclockwise direction, and the sliding touch stroke is relatively large, more delicate dimming can be achieved. In other words, high-precision dimming can be achieved to meet different dimming requirements. In addition, when the touch action does not stop and changes direction, when the main control PCB determines that the received signal changes from the first signal to the second signal, the control of the lamp light can change from gradually dimming to gradually brightening; or when the main control PCB determines that the received signal changes from the second signal to the first signal, the control of the lamp light can change from gradually brightening to gradually dimming to meet different dimming needs, and the operation is extremely convenient, making the present invention have strong market competitiveness.

[0027] The present invention will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0028] See Figures 1-3 As shown, there is a dimming device. The dimming device 1 includes a carrier 11, a touch control board 12 installed in the carrier 11, a light-transmitting cover 13 fixed to the upper end of the carrier 11 and covering the upper end of the touch control board 12, and a film 14 mounted on the upper end of the light-transmitting cover 13. When in use, by touching the film 14 with a finger, the touch control board 12 can collect touch actions.

[0029] Two groups of first antenna groups 15 and second antenna groups 16 for sensing touch actions are provided on the touch control board 12. Among them, the first antenna group 15 includes a plurality of first antennas 151 distributed in a clockwise ring in sequence. The area of the first antenna 151 gradually decreases from one end to the other end. When a clockwise touch action is performed on the first antenna group 15, the area of the first antenna 151 changes from large to small, thereby controlling the light of the lamp to gradually dim; the second antenna group 16 includes a plurality of second antennas 161 distributed in a counterclockwise ring in sequence. The area of the second antenna 161 gradually increases from one end to the other end. When a counterclockwise touch action is performed on the second antenna group 16, the area of the second antenna 161 changes from small to large, thereby controlling the light of the lamp to gradually brighten; and the first antenna 151 and the second antenna 161 are distributed in a staggered and reverse manner. The end with a small area of the second antenna 161 is located beside the end with a large area of the first antenna 151, and the end with a large area of the second antenna 161 is located beside the end with a small area of the first antenna 151, so that when a finger touches the film 14, it is sensed by both the first antenna 151 and the second antenna 161 at the same time.

[0030] The number of both the first antennas 151 and the second antennas 161 is 4.

[0031] During the use of the dimming device, the dimming device uses the first antenna group 15 to sense and collect the first signal of the touch action sliding clockwise, and at the same time uses the first antenna group 15 to sense and collect the second signal of the touch action sliding counterclockwise, and receives the first signal or the second signal through the main control PCB. When it is judged that the received signal is the first signal, the first action is performed to control the light of the lamp to gradually dim; when it is judged that the received signal is the second signal, the second action is performed to control the light of the lamp to gradually brighten; since the touch action refers to circular sliding touch in the clockwise or counterclockwise direction, and the sliding touch stroke is relatively large, more delicate dimming can be achieved. In other words, high-precision dimming can be realized to meet different dimming requirements. In addition, when the touch action does not stop and changes direction, when the main control PCB judges that the received signal changes from the first signal to the second signal, the control of the lamp light can be changed from gradually dimming to gradually brightening; or when the main control PCB judges that the received signal changes from the second signal to the first signal, the control of the lamp light can be changed from gradually brightening to gradually dimming to meet different dimming needs, and the operation is extremely convenient, making the present invention have extremely strong market competitiveness.

[0032] Preferably, the multiple first antennas 151 are sequentially distributed in a ring clockwise, which means that the multiple first antennas 151 are sequentially distributed in a circular ring (i.e., a circumference) clockwise; the multiple second antennas 16 are sequentially distributed in a ring counterclockwise, which means that the multiple second antennas 16 are sequentially distributed in a circular ring (i.e., a circumference) counterclockwise.

[0033] The sides of the adjacent first antenna 151 and the second antenna 161 are attached, so that the first antenna 151 and the second antenna 161 are close together, so that when a finger touches the diaphragm 14, it is simultaneously sensed by the first antenna 151 and the second antenna 161, and later the dimming or brightening of the light can be controlled according to the direction of the touch slide, and the operation is more convenient.

[0034] The small-area end of the previous first antenna 151 is located beside the large-area end of the next first antenna 151, and they are sequentially assembled into a ring; the small-area end of the previous second antenna 161 is located beside the large-area end of the next second antenna 161, and they are sequentially assembled into a ring.

[0035] The carrier 11 includes a base 111 and an upper cover 112 sleeved on the outer periphery of the upper end of the base 111. The middle part of the upper end of the base 111 passes through the upper cover 112. The touch control board 12, the light-transmitting cover 13 and the diaphragm 14 are sequentially arranged on the middle part of the upper end of the base 111 from bottom to top and are exposed in the upper cover 112, and their assembly is extremely convenient.

[0036] A ring groove 110 is formed between the periphery of the middle part of the upper end of the base 111 and the inner wall of the upper cover 112. A handle 113 that can be received and opened outward to protrude above the upper cover 112 is arranged in the ring groove 110. When using the handle 113, the handle 113 can be unfolded relative to the ring groove 110, so that the upper end of the handle 113 protrudes above the upper cover 112 for the user to lift by hand; when not in use, the handle 113 is folded and received in the ring groove 110 so that the handle 113 will not affect the normal use of the dimming device.

[0037] In summary, during the use of the dimming device, the dimming device uses the first antenna group 15 to sense and collect the first signal of the touch action sliding clockwise, and at the same time uses the first antenna group 15 to sense and collect the second signal of the touch action sliding counterclockwise, and receives the first signal or the second signal through the main control PCB. When it is judged that the received signal is the first signal, the first action is performed to control the light of the lamp to gradually dim; when it is judged that the received signal is the second signal, the second action is performed to control the light of the lamp to gradually brighten; because the touch action refers to circular sliding touch in the clockwise or counterclockwise direction, and the sliding touch stroke is relatively large, more delicate dimming can be achieved. In other words, high-precision dimming can be realized to meet different dimming requirements. In addition, when the touch action does not stop and changes direction, when the main control PCB judges that the received signal changes from the first signal to the second signal, the control of the light of the lamp can be changed from gradually dimming to gradually brightening; or when the main control PCB judges that the received signal changes from the second signal to the first signal, the control of the light of the lamp can be changed from gradually brightening to gradually dimming to meet different dimming needs, and the operation is extremely convenient, making the present invention highly competitive in the market.

The battery 4 is used to supply power to the multi-angle LED light-emitting module 5, the touch control board 12, and the main control PCB 17. The dimming device 1 is used to dim the multi-angle LED light-emitting module 5. The multi-angle LED light-emitting module 5 can emit light 360 degrees around to increase the light-emitting area and improve the lighting effect.

[0039] A plurality of grooves 21 distributed from top to bottom are provided on the periphery of the lantern-shaped lamp cover 2, and decorative reinforcing ribs 22 are provided in the grooves 21. The decorative reinforcing ribs 22 can reinforce the lantern-shaped lamp cover 2, increase the strength of the overall structure, improve the service life, and also play a decorative role, facilitating the improvement of market competitiveness.

[0040] The multi-angle LED lighting module 5 includes an aluminum rod 51 fixedly connected to the carrier 11 and having a polygonal cross-section, and a plurality of LED lamp boards 52 fixed to the outer side surface of the aluminum rod 51. Each LED lamp board 52 emits light in one direction, thereby achieving multi-directional light emission to increase the light-emitting area and improve the lighting effect. The lower end of the aluminum rod 51 is also fixedly connected to the bottom cover 3 to ensure the stability of the assembly structure of the multi-angle LED lighting module 5.

[0041] The lamp is placed on the tray 6, and a wireless charging module 61 is provided inside the tray 6. A coil module 31 adapted to the wireless charging module 61 is also provided inside the bottom cover 3. The tray 6 can be used as a decorative tray for carrying the lamp to form a table lamp. And the wireless charging module 61 is provided inside the tray 6. After the lamp is placed on the tray 6, the coil module 31 inside the bottom cover 3 of the lamp is matched and docked with the wireless charging module 61, and the wireless charging module 61 charges the battery wirelessly through the coil module 31.

[0042] In summary, the lamp of the present invention uses the above-mentioned dimming device, and the multi-angle LED lighting module 5 is dimmed through the dimming device to meet different usage requirements and has the technical effects of the dimming device. The lamp of the present invention uses the multi-angle LED lighting module 5 to achieve multi-directional light emission to increase the light-emitting area and improve the lighting effect.

[0043] The present invention also provides a dimming method, which is as follows:

[0044] The first step: Define the touch action of sliding clockwise as the first action to control the light of the lamp to gradually dim; define the touch action of sliding counterclockwise as the second action to control the light of the lamp to gradually brighten.

[0045] Step 2: The first antenna group 15 senses and collects the first signal of the touch action sliding clockwise, and at the same time, the first antenna group 15 senses and collects the second signal of the touch action sliding counterclockwise, and receives the first signal or the second signal through the main control PCB. When it is judged that the received signal is the first signal, a first action is performed to control the light of the lamp to gradually dim; when it is judged that the received signal is the second signal, a second action is performed to control the light of the lamp to gradually brighten; when the touch action does not stop and changes direction, when the main control PCB judges that the received signal changes from the first signal to the second signal, the control of the light of the lamp can be changed from gradually brightening to gradually dimming; or when the main control PCB judges that the received signal changes from the second signal to the first signal, the control of the light of the lamp can be changed from gradually dimming to gradually brightening.

[0046] The dimming method of the present invention uses circular sliding touch clockwise or counterclockwise, and the sliding touch stroke is relatively large, which can achieve more delicate dimming. In other words, it can achieve high-precision dimming to meet different dimming requirements. In addition, when the touch action does not stop and changes direction, when the main control PCB judges that the received signal changes from the first signal to the second signal, the control of the light of the lamp can be changed from gradually brightening to gradually dimming; or when the main control PCB judges that the received signal changes from the second signal to the first signal, the control of the light of the lamp can be changed from gradually dimming to gradually brightening to meet different dimming needs, and the operation is extremely convenient, making the present invention highly competitive in the market.

[0047] The first antenna group 15 includes a plurality of first antennas 151 arranged in a ring clockwise in sequence. The area of the first antenna 151 gradually decreases from one end to the other end. When a clockwise touch action is performed on the first antenna group 15, the area of the first antenna 151 decreases from large to small to control the light of the lamp to gradually dim; the second antenna group 16 includes a plurality of second antennas 161 arranged in a ring counterclockwise in sequence. The area of the second antenna 161 gradually increases from one end to the other end. When a counterclockwise touch action is performed on the second antenna group 16, the area of the second antenna 161 increases from small to large to control the light of the lamp to gradually brighten; and the first antenna 151 and the second antenna 161 are arranged in an interleaved and reverse manner. The end with a small area of the second antenna 161 is located beside the end with a large area of the first antenna 151, and the end with a large area of the second antenna 161 is located beside the end with a small area of the first antenna 151. The sides of the adjacent first antenna 151 and the second antenna 161 are in contact, so that when touching on the diaphragm 14, it is simultaneously sensed by the first antenna 151 and the second antenna 161.
