Description

Technical Field

[0001] This utility model relates to the field of driving power supply equipment technology, and in particular to a power supply device. Background Technology

[0002] Existing power supply devices used in the lighting field include a power modulation module. This module connects to the power supply and modulates the output of the input power to form a power supply adapted to power the light source. The power supply device also includes a photosensitive sensor that detects the ambient light intensity. When the light intensity is below a light intensity threshold, the control module controls the output of the power modulation module to turn on the light source. When the light intensity is above the light intensity threshold, the control module controls the power modulation module to turn off the light source. To prevent false triggering, the light intensity needs to remain above the light intensity threshold for a certain delay before the control module turns off the power modulation module. However, the user is unaware of this process and cannot determine when the light source will turn off. Utility Model Content

[0027] like Figures 1 to 4 As shown, a power supply device according to a first aspect embodiment of the present invention includes a housing 100, a photosensitive sensor 210, a display module 220, a power modulation module 230, a control module 240, and a timing module 250. The housing 100 is at least partially provided with a transparent portion 140, which is made of a transparent or semi-transparent material. The photosensitive sensor 210 is disposed within the housing 100 and corresponds to the transparent portion 140. The photosensitive sensor 210 is used to detect signals through the transparent portion 140. The light intensity outside the housing 100 is measured. The display module 220 is disposed inside the housing 100 and corresponds to the transparent part 140. The power modulation module 230 is disposed in the housing 100, and the output terminal of the power modulation module 230 is used to connect to the load. The control module 240 and the timing module 250 are disposed inside the housing 100. The control module 240 is connected to the photosensitive sensor 210, the display module 220, the timing module 250 and the power modulation module 230 respectively.

[0028] The housing 100 can be cylindrical, cuboid, or other irregular shapes. The power modulation module 230 can include a rectifier and voltage regulator unit, a switching power supply unit, and a transformer unit. The rectifier and voltage regulator unit can include a full-wave or half-wave rectifier bridge and a filter capacitor. The input terminal of the rectifier and voltage regulator unit is connected to an external power supply via a wire. The switching power supply unit can include a switching power supply chip, a semiconductor switching transistor, a transformer, etc. The output terminal of the rectifier and voltage regulator unit is connected to the primary coil of the transformer and the input terminal of the switching transistor, respectively. The output terminal of the switching transistor is grounded. The switching power supply chip is connected to the controlled terminal of the switching transistor. The switching power supply chip controls the switching transistor to adjust the input voltage of the transformer, thereby adjusting the output voltage of the transformer. The output voltage can be output at the output terminal of the power modulation module 230 to power the load. The transformer unit can include a transformer chip and its auxiliary circuits. The output voltage can be input to the input terminal of the transformer unit. The transformer unit modulates the input voltage and outputs it, which can be used as a power supply to power the control module 240, the photosensitive sensor 210, the display module 220, etc.

[0029] The photosensitive sensor can be a conventional photosensitive chip that detects light intensity; the display module 220 can be a digital tube, RGB display screen, etc.; the timing module 250 can be a conventional crystal oscillator circuit or an integrated timing chip; the control module 240 can include an MCU or CPU and its auxiliary circuits; the control module 240 can be connected to a switching power supply chip to control the output voltage.

[0030] In this utility model power supply device, at least a portion of the housing 100 is provided with a viewing portion 140. The photosensitive sensor 210 and the display module 220 are located inside the housing 100 and close to the viewing portion 140. No openings are needed on the housing 100 to mount the photosensitive sensor 210 and the display module 220. Both external light and the light output from the display module 220 can pass through the viewing portion 140. The power modulation module 230 is connected to the power supply and modulates the output of the input power supply to form a power supply adapted to power the light source. The photosensitive sensor 210 can detect the ambient light intensity based on the light entering from the viewing portion 140. When the light intensity is lower than the light intensity threshold, the control module 240 can control the output of the power modulation module 230 to drive the light source to light up. When the light intensity is higher than the light intensity threshold, the control module 240 can control the output of the power modulation module 230 to drive the light source to light up. When the light intensity exceeds the threshold, the timing module 250 provides timing information to the control module 240. Only when the light intensity is continuously higher than the light intensity threshold and the duration reaches the time threshold will the control module 240 control the power modulation module 230 to stop outputting. When the light intensity is higher than the light intensity threshold, the control module 240 displays a countdown before the light source turns off through the display module 220 based on the timing information. When the countdown reaches zero, the light source turns off. The control module 240 presents the user with the time information about the start and stop of the light source through the display module 220. This design has a compact structure, clearly presents the control status to the user, and is convenient and reliable to use. In addition, the control module 240 can also control the power modulation module 230 to enter various different modulation modes, and the display module 220 can use the serial number to indicate which modulation mode is currently in.

[0031] In some embodiments of this utility model, such as Figure 2 As shown, the housing 100 includes a base 110, a sleeve 120, and a top cover 130. The base 110, the sleeve 120, and the top cover 130 are connected to define an inner cavity. The bottom end of the sleeve 120 is disposed on the base 110, and the top end of the sleeve 120 is provided with an opening 150. The top cover 130 is connected to the top end of the sleeve 120 to close the opening 150. The top cover 130 is made of transparent or semi-transparent material to form the transparent portion 140. The photosensitive sensor 210, the display module 220, the power modulation module 230, the control module 240, and the timing module 250 are all located in the inner cavity.

[0032] Since the housing 100 needs to be at least partially configured as a transparent portion 140, the top cover 130 is selected to be made of a transparent or semi-transparent material. In some embodiments of this utility model, the top cover 130 is made of PC or glass, while the base 110 and the housing 120 can still be made of opaque materials, such as plastic or alloy, so that the internal electronic components are not easily exposed to the user's view and affect the user's perception. In addition, when used outdoors, sunlight will directly shine on the internal electronic components, accelerating the aging of the electronic components.

[0033] In some embodiments of this utility model, the top cover 130 and the top of the housing 120 are detachably connected, and an elastic sealing ring 160 is provided between the edge of the opening 150 of the housing 120 and the top cover 130.

[0034] When the display module 220 and photosensitive sensor 210 need to be replaced, the top cover 130 can be removed from the housing 120, and then the display module 220 and photosensitive sensor 210 can be repaired or replaced directly at the opening 150 of the housing 120. The elastic sealing ring 160 can prevent dust and moisture in the air from entering the inner cavity.

[0035] In some embodiments of this utility model, such as Figure 2 As shown, multiple sets of screw assemblies 300 are provided between the top cover 130 and the housing 120, and the housing 120 is detachably connected to the top cover 130 through the screw assemblies 300.

[0036] There may be multiple screw assemblies 300, and the multiple screw assemblies 300 are distributed around the opening 150. Each screw assembly 300 includes a threaded hole 310 provided on the housing 120, a through hole 320 provided on the top cover 130, and a bolt 330. The bolt 330 passes through the through hole 320 and the threaded hole 310 to connect the housing 120 and the top cover 130.

[0037] In some embodiments of this utility model, such as Figure 2 As shown, a first circuit board 410 and a second circuit board 420 are disposed inside the housing 100. The first circuit board 410 and the second circuit board 420 are arranged in layers. The first circuit board 410 is located below the second circuit board 420. The transparent part 140 is located at the top of the housing 100. The power modulation module 230 is disposed on the first circuit board 410. The photosensitive sensor 210 and the display module 220 are disposed on the second circuit board 420 close to the transparent part 140.

[0038] The first circuit board 410 can be mounted on the base 110. A bracket can be provided between the first circuit board 410 and the second circuit board 420 for support. By layering the first circuit board 410 and the second circuit board 420, the power modulation module 230, the photosensitive sensor 210, and the display module 220 are separated from each other, making them less likely to interfere with each other. The heat generated by the operation of the power modulation module 230 is also less likely to affect the detection accuracy of the photosensitive sensor 210. With the support of the first circuit board 410 and the bracket, the second circuit board 420 brings the photosensitive sensor 210 and the display module 220 closer to the top viewing section 140, making it easier for light to pass through the viewing section 140.

[0039] In some embodiments of this utility model, a conductive component is provided at the bottom of the housing 100, and the output terminal of the power modulation module 230 is connected to the conductive component.

[0040] Conductive components can be conductive plugs, conductive sockets, conductive clips, etc., and can be connected to corresponding plugs, conductive wires, busbars, etc. to output electrical energy.

[0041] In some embodiments of this utility model, such as Figure 2 , 3 As shown in Figure 4, the housing 100 also includes a wireless receiving module 500 and a magnetic drive switch module 600. The wireless receiving module 500 is used to receive wireless signals when powered on. The wireless receiving module 500 is connected to the control module 240. The magnetic drive switch module 600 can be driven to conduct when it senses the magnetic block approaching. The wireless receiving module 500 and the magnetic drive switch module 600 are connected to form at least a partial power supply branch, which is used to connect to the power supply.

[0042] The wireless receiving module 500 can be an infrared receiver, Bluetooth module, WiFi module, etc., and the magnetic drive switch module 600 can be a self-resetting switch. When the magnetic block moves away from the magnetic drive switch module 600, the magnetic drive switch module 600 will automatically disconnect. In some embodiments of this utility model, the magnetic drive switch module 600 can also be a switching switch. Each time the magnetic block approaches, the magnetic drive switch module 600 will switch its switching state, that is, switch from the on state to the off state or switch from the off state to the on state.

[0043] Understandably, in standby mode, the magnetic drive switch module 600 is off, and the power supply fails to power the wireless receiver module 500. The wireless receiver module 500 cannot receive wireless signals when it is de-energized. When the user needs the power device to receive wireless signals, a remote control with a magnetic block can be brought close to the magnetic drive switch module 600. The magnetic drive switch module 600 will then conduct, energizing the wireless receiver module 500. At this time, the user can operate the remote control to send a wireless signal, which the wireless receiver module 500 will then receive. Since the magnetic drive switch modules 600 of other power devices in the area are not conducting, their wireless receiver modules 500 cannot receive wireless signals. Therefore, these wireless signals do not require identification codes, making operation simple and control reliable.

[0044] In some embodiments of this utility model, such as Figure 2 As shown, the magnetic drive switch module 600 is disposed on the second circuit board 420 close to the transparent part 140. Since the light emitted by the display module 220 can pass through the transparent part 140, the magnetic drive switch module 600 is disposed close to the transparent part 140 with the light emitted by the transparent part 140 as an indicator. The user can drive the magnetic drive switch module 600 to conduct by bringing the remote control close to the transparent part 140 under the indicator of the light.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
