The technical scheme of the application is described in detail below by specific examples. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.
FIG. 1 is a schematic diagram of an induction bulb according to the present application; referring to fig. 1, the bulb includes: a housing structure 11, an optical cover 12, a light transmissive cover 13, a first carrier 14 disposed within the housing structure 11, an event sensing circuit 21, and a brightness sensing circuit 22.
The event sensing circuit 21 is configured to detect whether a trigger event occurs in the sensing range; a triggering event is understood to be an event that senses the presence or physical activity within a range.
The brightness sensing circuit 22 is configured to detect brightness in a sensing range.
The optical cover 12 is arranged at a first open end of the housing structure 11 for outgoing light, and a first side of the first carrier 14 faces the first open end. Referring to fig. 1, the first open end can be understood as the upper end in fig. 1.
The light-transmitting cover 13 is covered on the first side surface of the first carrier 14 to form a cavity between the light-transmitting cover 13 and the first carrier 14, and the event sensing circuit 21 and the brightness sensing circuit 22 are both disposed on the first side surface of the first carrier 14 and are located in the cavity.
The optical cover 12 and the light-transmitting cover 13 may be any cover capable of transmitting light, for example, a lens may be used, and the shape and configuration of the lens may be further adjusted by the optical cover 12 in order to facilitate light output and distribution.
According to the induction type bulb provided by the application, the event induction circuit 21 is used for detecting whether a trigger event occurs in an induction range, the brightness induction circuit 22 is used for detecting brightness of the induction range, and the event induction circuit 21 and the brightness induction circuit 22 are arranged in the shell structure 11, so that the event induction circuit 21 and the brightness induction circuit 22 are integrated in the bulb, and only the bulb is required to be integrally replaced when the bulb is replaced and assembled, so that the bulb is convenient to assemble and replace.
Meanwhile, the first side surface of the first carrier 14 is covered by the light-transmitting cover 13, so that a cavity is formed between the light-transmitting cover 13 and the first carrier 14, and the event sensing circuit 21 and the brightness sensing circuit 22 are arranged on the first side surface of the first carrier 14 and are positioned in the cavity, so that the uniform arrangement of the event sensing circuit 21 and the brightness sensing circuit 22 is realized, the space is effectively saved, and the uniformity and the pertinence of the detection range are higher due to the uniform arrangement of the event sensing circuit 21 and the brightness sensing circuit 22.
Fig. 2 is a schematic circuit diagram of an induction bulb according to the present application.
Referring to fig. 2, in one embodiment, the bulb further includes: the light-emitting module 25, the control module 23 and the light-emitting driving module 24 are arranged in the shell structure 11, and the control module 23 is connected with the light-emitting driving module 24; the light emitting module 25 is connected to the light emitting driving module 24, and the event sensing circuit 21 and the brightness sensing circuit 22 are both connected to the control module 23.

The brightness sensing circuit 22 is further configured to generate and send a second trigger signal to the control module 23 when the detected brightness is below a threshold value.
The control module 23 is configured to send a control signal to the light-emitting driving module 24 according to the first trigger signal and the second trigger signal. In this way, it can be understood that the control signal is transmitted only when the first trigger signal and the second trigger signal are obtained.
The light-emitting driving module 24 is configured to drive the light-emitting module 25 to emit light according to the control signal.
Since the light emitting module 25 is driven to emit light only when the trigger event is detected and the brightness is detected to be lower than the threshold value, the trigger event and the brightness are used as the necessary conditions for driving the light emission under the condition that the brightness sensing circuit 22 and the event sensing circuit 21 are integrated at the same time, and compared with the scheme of using only the brightness sensor and the scheme of using only the human body sensor in the prior art, the application can drive the light emission more specifically and further saves energy consumption.
Fig. 3 is a schematic diagram of a first induction bulb according to the present application.
Referring to fig. 3, in one embodiment, the bulb further includes: the second carrier 15 is disposed in the housing structure 11, the first side surface of the second carrier 15 faces the first opening end, the first carrier 14 is disposed on the first side surface of the second carrier 15, and the light emitting modules 25 are disposed on the first side surface of the second carrier 15 and distributed on the outer periphery of the first carrier 14.
Through the layout of the light emitting module 25, the light emission of the light emitting module 25 can be prevented from being affected by the first carrier 14, meanwhile, since the orientation of the first carrier 14 is consistent with that of the second carrier 15, and the first carrier 14 is arranged on the first side surface of the second carrier 15, the space in the housing structure 11 can be effectively saved, so that the space occupation caused by the integration of the event sensing circuit 21 and the brightness sensing circuit 22 can be compensated.
In one embodiment, the bulb further comprises: a third carrier 16 disposed within the housing structure 11, the control module 23 and the light-emitting drive module 24 being disposed on the third carrier 16; the third carrier 16 is inserted into the second carrier 15, and the control module 23 and the light-emitting driving module 24 are located on a side of the second carrier 15 opposite to the first side. The connection between the second carrier 15 and the third carrier 16 can be facilitated by the plugging of the third carrier 16.
In one embodiment, a middle hole is formed in the middle of the second carrier 15, and the third carrier 16 is disposed through the middle hole of the second carrier 15. Wherein, the middle hole can be provided with a groove, and the third carrier 16 can be inserted into the groove. It is also possible to save space on the basis of maintaining a firm connection between the second carrier 15 and the third carrier 16. In a specific implementation, the third carrier 16 may be perpendicular to the second carrier 15.
Meanwhile, the third carrier 16 is penetrated through the middle hole, so that the third carrier 16 and the first carrier 14 are not blocked by the second carrier 15, connection between the circuit on the first carrier 14 and the circuit on the third carrier 16 can be facilitated, and particularly, the connected circuit can be simpler and safer. Therefore, referring to fig. 3, in one embodiment, the first carrier 14 and the third carrier 16 are connected by a first connection circuit, so that: the event sensing circuit 21 and the brightness sensing circuit 22 can be connected to the control module 23 through the first connection line, and the second carrier 15 and the third carrier 16 are connected through the second connection line, so that: the light emitting module 25 can be connected to the light emitting driving module 24 through the second connection line.
In one embodiment, the bulb further includes a lamp cap 17, the lamp cap 17 is disposed at the second open end of the housing structure 11, and the circuit in the bulb can be wired to the outside through the lamp cap 17. In addition, the opening of the first opening end of the housing structure 11 is large, which can be used for light emission, the opening of the second opening end is small, which can be used for external connection, and the housing structure 11 is reduced from large to small along the direction from the first opening end to the second opening end. Wherein the design of the third carrier 16 perpendicular to the second carrier 15 is effectively adapted to the shape design of the housing structure 11. And to further accommodate the shape of the housing structure 11 and to save space, the shape of the third carrier 16 may be designed such that the end near the first open end is large and the end near the second open end is small.
