Figs. 1-8 are structural schematic views of the intelligent lamp provided by embodiments of the present application, where the meanings of the reference signs in the drawings are referred to as: bulb shell 10, lamp holder shell 60, filament assembly 20, annular antenna 30, connection terminal 40 and assembled control board 50, first sub-substrate 501, second sub-substrate 502, through-hole 5021, support portion 5011, support surface 601.
It should be noted that, regardless of the bulb shell 10 or the lamp holder shell 20, the shapes of the shells as shown in Figs. 1-8 are only schematic. In practical applications, both the shapes and sizes of the shells may be arranged according to actual needs, which should not be construed as limitation to the present application.
The intelligent lamp provided by the present application is described in detail below with reference to the accompanying drawings. Referring to Fig. 1, an embodiment of the present application provides an intelligent lamp including: a bulb shell 10, a filament assembly 20, a annular antenna 30, a connection terminal 40, an assembled control board 50 and a lamp holder shell 60. The filament assembly 20 and the assembled control board 50 are arranged in a cavity formed by combination of the bulb shell 10 and the lamp holder shell 60. The annular antenna 30 is arranged on an exterior of the shell at an opening of the bulb shell 10, and is electrically connected to the assembled control board 50 through the connection terminal 40. The filament assembly 20 is electrically connected with the assembled control board 50.
Fig. 1 is an exploded schematic view showing a planar configuration of the components of the intelligent lamp, which, from top to bottom, includes:
the bulb shell 10, the filament assembly 20, the annular antenna 30, the connection terminal 40, the assembled control board 50 and the lamp holder shell 60.
As shown in Fig. 1, the bulb shell 10 is a shell structure provided with an opening at its bottom, and the lamp holder shell 60 is a shell structure provided with an opening at its top. After the intelligent lamp is assembled, the bulb shell 10 and the lamp holder shell 60 are combined together to form a closed cavity, and the filament assembly 20, the annular antenna 30, the connection terminal 40 and the assembled control board 50 are disposed inside of the cavity. Where, the inner diameter of the opening of the lamp holder shell 60 is larger than the outer diameter of the opening of the bulb shell 10, therefore, referring to Fig. 8, the lower portion of the bulb shell 10 (i.e., toward the direction of the lamp holder shell) will be wrapped inside the shell of the lamp holder shell 60 after the bulb shell 10 is combined with the lamp holder shell 60.
Wherein, the bulb shell 10 is a light-transmissive member, and the material of the light-transmissive member may be selected from polymer materials such as PP (polypropylene), PC (polycarbonate), PS (polystyrene), PET (polyethylene terephthalate), PE (polyethylene) and the like, so as to ensure that the emitted light is uniform and soft while the light transmittance is relatively high.
In order to receive and transmit signals, an antenna needs to be provided in the intelligent lamp. The antenna may capture a high-frequency electromagnetic signal transmitted wirelessly, and then convert the high-frequency electromagnetic signal into a high-frequency voltage signal or a high-frequency current signal, and transmit it to a control module of the intelligent lamp. Alternatively, the high-frequency electromagnetic signal generated by the control module is radiated to the space environment where the intelligent lamp is located in a form of electromagnetic waves, to realize wireless transmission of the signal.
In this embodiment of the present application, the antenna is designed as an annular structure, that is, the annular antenna 30 as shown in Fig. 2.
Fig. 2 is a structural schematic view showing separation of the bulb shell and the annular antenna. After the intelligent lamp is assembled, the annular antenna 30 will be disposed on the exterior of the shell at the opening of the bulb shell 10.
Illustratively, in one implementation in which the bulb shell 10 is coupled to the annular antenna 30, the bulb shell 10 is provided with an antenna fitting slot at the opening, and the annular antenna 30 is disposed within the antenna fitting slot. In order to stably combine the slot and the antenna together, the size of the antenna fitting slot may be designed with a high precision to match the annular antenna 30, so that the annular antenna 30 is tightly embedded in the antenna fitting slot, alternatively, the antenna fitting slot is bonded with the annular antenna 30 by using glue.
Illustratively, in another implementation in which the bulb shell 10 is coupled to the annular antenna 30, the inner diameter of the annular antenna 30 matches the outer diameter of the opening of the bulb shell 10, i.e., the inner diameter of the annular antenna 30 is only greater than the outer diameter of the opening of the bulb shell 10, such that the annular antenna 30 may be fitted into the opening of the bulb shell 10, and the two are bonded together by using the glue in order to stably bond the two together.
In this embodiment of the present application, the antenna is designed as an annular structure, and the annular antenna 30 is arranged at the opening of the bulb shell 10, thereby effectively utilizing the shape structures of the existing components of the lamp, avoiding adding a specialized injection molded part for placing the antenna, and further saving manufacturing cost. At the same time, since there are a large number of bulb shells with openings in the market, the annular antenna are is highly versatile, and the annular antenna may be designed according to different sizes of the openings of the bulb shells so as to adapt different bulb shells on the market.
In the present application, the antenna provided with an annular structure is designed. In order to ensure effective transmission of the wireless control signal in the intelligent lamp, an embodiment of the present application further designs a connection manner between the annular antenna 30 and the control module, as shown in Fig. 3. Fig. 3 is a structural schematic view showing connection of the annular antenna and the control module, where one end of the connection terminal 40 is connected to the annular antenna 30, and the other end of the connection terminal 40 is connected to a first sub-substrate 501.
In an implementation of the connection structure as shown in Fig. 3, one implementation may be as follows: the connection terminal 40 is a metal elastic member, one end of the metal elastic member is soldered on the first sub-substrate, and the other end of the connection terminal 40 is connected in contact with the annular antenna 30. Due to the elastic structure of the connection terminal 40, the connection terminal 40 will be pressed when the intelligent lamp is assembled, thereby ensuring close contact between the connection terminal 40 and the annular antenna 30.
Referring to Fig. 4 and Fig. 5, Fig. 4 is a structural schematic view showing separation of the connection terminal, the first sub-substrate and a second sub-substrate, and Fig. 5 is a structural schematic view showing the annular antenna, the connection terminal, the first sub-substrate and the second sub-substrate after the intelligent lamp is assembled.
In this embodiment of the present application, the assembled control board 50 includes a substrate, and a control module and a driving module respectively arranged on the substrate. The substrate includes the first sub-substrate 501 and the second sub-substrate 502. The control module is arranged on the first sub-substrate 501, and the driving module is arranged on a surface of the second sub-substrate 502 facing toward the bottom of the lamp holder shell.
Therefore, the annular antenna 30 is electrically connected to the assembled control board 50 through the connection terminal 40, specifically, the annular antenna 30 is electrically connected to the first sub-substrate 501 through the connection terminal 40, and the control module is arranged above the first sub-substrate 501. The filament assembly 20 is electrically connected to the assembled control board 50, specifically, the filament assembly 20 is electrically connected to the second sub-substrate 502, and the driving module is arranged above the second sub-substrate 502.
Referring to Fig. 4 and Fig. 5, in an implementation of the connection structure as shown in Fig. 3, one implementation may be as follows: the first sub-substrate 501 is vertically arranged on the second sub-substrate 502 by passing through the through-hole 5022 of the second sub-substrate, and a portion of the first sub-substrate 501 passing out the through-hole 5022 is connected to the connection terminal 40.
In a practical application, the filament assembly 20 is electrically connected to the driving module, and the driving module is configured to supply power for the filament assembly after an alternating current is converted into a direct current. The connection terminal 40 is electrically connected to the control module, and the control module is configured to receive a wireless control signal through the annular antenna, such that the power supply for the filament assembly by the driving module is controlled.
Specifically, the control module may control the strength of the power supplied by the driving module, or control whether the driving module supplies power for power supply. Correspondingly, the strength of the power supplied may be controlled by adjusting the brightness of the intelligent lamp, and whether the power is supplied may be controlled by controlling turning on or turning off the intelligent lamp.
In one embodiment, the control module includes a radio-frequency circuit and a radio-frequency power supply circuit, and the radio-frequency power supply circuit is configured to supply power to the radio-frequency circuit. Illustratively, components in the radio-frequency circuit may include a filter, a power amplifier and a radio-frequency transceiver. The radio-frequency transceiver may further include a receiver, a transmitter, a frequency synthesizer, a voltage-controlled oscillator and a voltage regulator.
Regarding the arrangement of the driving module on the second sub-substrate 502, in an embodiment of the present application, the driving module provided with a magnetic device thereon and passed through by a large high-voltage alternating current is considered, which affects the wireless performance of the antenna easily, and therefore the driving module is arranged on a surface of the second sub-substrate 502 facing away from the annular antenna 30 (i.e., the surface facing toward the bottom of the lamp holder shell).
Illustratively, the metal material of the annular antenna 30 may be any one of gold, silver, copper, palladium, platinum, nickel, or nickel plating on stainless steel, or a combination of any two or more thereof.
Regarding the selection of a connection point between the connection terminal 40 and the annular antenna 30 on the annular antenna 30, the connection point may be at any part of an annular surface of the annular antenna 30 facing toward the first sub-substrate, since the annular antenna 30 is entirely made of a metal material.
In this embodiment of the present application, due to that the antenna is arranged as an annular structure and that the annular antenna 30 is entirely made of a metal material, therefore, the connection may be achieved as long as the connection terminal 40 is ensured to be connected to the annular antenna 30, and it is not necessary for the connection terminal 40 to be positioned and manufactured with high precision, thereby reducing the requirement for assembly accuracy in the production process and further improving the production efficiency.
As shown in Fig. 1 and Fig. 4, the second sub-substrate 502 is horizontally arranged inside the lamp holder shell 60 with the orientation of the opening of the bulb shell 10 as a vertical direction.
As shown in Fig. 4 and Fig. 5, the second sub-substrate 502 is provided with a through-hole 5022 thereon, and the first sub-substrate 501 is vertically arranged on the second sub-substrate 502 by passing through the through-hole 5022.
Regarding fixing the first sub-substrate 501 inside the cavity formed by the bulb shell 10 and the lamp holder shell 60, a corresponding structure has been designed in an embodiment of the present application (referring to Fig. 6 for details). Fig. 6 is a schematic view showing the shape of the first sub-substrate.
As shown in Fig. 6, the first sub-substrate 501 may include the following portions based on the outer shape of the first sub-substrate 501: a first fitting portion, a second fitting portion, a first support portion and a second support portion. The lamp holder shell 60 is provided with a support surface 601, and the support surface 601 is provided with a through-hole thereon, and an end of the first sub-substrate 501 facing toward the lamp holder shell 60 is arranged on the support surface 601 through the through-hole.
In an embodiment of the present application, the first fitting portion is a portion of the first sub-substrate 501 passing through the through-hole 5022, the second fitting portion is a portion of the first sub-substrate 501 passing through the through-hole of the support surface 601, the first support portion is a portion of the first sub-substrate 501 passing through the through-hole 5022 and then catching a bottom surface of the second sub-substrate 502 (i.e., a surface facing toward the lamp holder shell), and the second support portion is a portion of the first sub-substrate 501 passing through the through-hole of the support surface 601 and then catching the support surface 601.
In a practical application, after the intelligent lamp is assembled, since one end of the first sub-substrate 501 is vertically arranged on the second sub-substrate 502 by passing through the through-hole 5022, the through-hole 5022 is a narrow strip-shaped through-hole, and the length of the first fitting portion of the first sub-substrate 501 is required to be less than or equal to the length of the strip-shaped through-hole, and the thickness of the first fitting portion is required to be less than or equal to the width of the strip-shaped through-hole. The first fitting portion of the first sub-substrate 501 passes through the through-hole 5022 and then is fixed with respect to the second sub-substrate 502.
In a practical application, after the intelligent lamp is assembled, since the other end of the first sub-substrate 501 is vertically arranged on the support surface 601 by passing through the through-hole of the support surface 601, the through-hole of the support surface 601 is a narrow strip-shaped through-hole, and the length of the second fitting portion of the first sub-substrate 501 is required to be less than or equal to the length of the through-hole of the support surface 601, and the thickness of the second fitting portion is required to be less than or equal to the width of through-hole of the support surface 601. The second fitting portion of the first sub-substrate 501 passes through the through-hole of the support surface 601 and then is fixed with respect to the lamp holder shell 60.
In conclusion, in the embodiments of the present application, the antenna is designed as an annular structure, which may be directly arranged at the opening of the bulb shell, and may realize reliable electrical connection through the connection terminal and the assembled control board in the shell, thus there is no need to additionally arrange an injection molded part in the lamp, thereby saving the manufacturing cost of the products. In addition, since the antenna is a structure and its contact area is large, thus it is not necessary to position and manufacture the connection terminal connected thereto with high precision, thereby reducing the requirement for assembly precision during the production process and further improving the production efficiency.
