Referring to fig. 1 to 3, as shown in fig. 1, the mobile terminal 100 is a schematic structural diagram of a lighting device fixed on a mobile terminal according to an embodiment of the present disclosure, and includes a body 110, a display screen 120 fixed to the body 110, a detection element 130, a control element 140, and a hall switch 150, where the detection element 130 is used to detect a display state of the display screen 120, the hall switch 150 is used to turn on and off according to a distance between the lighting device 200 and the mobile terminal 100, and the control element 140 is used to control the lighting device 200 to turn on and turn off according to a state and a display state of the hall switch 150.
In the present embodiment, the hall switch 150 is similar to a proximity switch, and is automatically activated to turn on or off according to the distance between two objects. The display state of the display 120 of the mobile terminal 100 includes a bright screen and a dark screen, the display state of the display 120 is bright when the user is using the mobile terminal, and the display state of the display 120 is dark screen when the user is not using the mobile terminal. The control unit 140 is a unit that can operate and execute instructions according to a predetermined program or logical relationship.
In practical application, when the lighting device 200 approaches the mobile terminal 100, the hall switch 150 is triggered to be turned on, and meanwhile, when the display screen 120 is bright, the control element 140 controls the lighting device 200 to be turned on according to the turning on of the hall switch 150 and the bright screen display state of the display screen 120; when the lighting device 200 is far away from the mobile terminal 100, the hall switch 150 is triggered to turn off, and at this time, the control element 140 does not control the lighting device 200 to be turned on regardless of whether the display state of the display screen 120 is on or off.
Like this, through turning on or turning off of mobile terminal 100 automatic control lighting apparatus 200 for control is more intelligent, and meanwhile, when opening of hall switch 150 and the display state of display screen 120 are bright, lighting apparatus 200 is controlled automatically to mobile terminal 100, has avoided when the user does not use mobile terminal, and lighting apparatus 200 still lights, causes the wasting of resources.
Further, the lighting device 200 includes a first electromagnetic component, when the distance between the lighting device 200 and the mobile terminal 100 is smaller than a first preset range, the first electromagnetic component triggers the hall switch 150 to be in an on state, and the control element 140 is configured to light the lighting device 200 when the hall switch 150 is in the on state and the display state is a bright screen.
Specifically, the first preset range is a preset distance range of the lighting device 200 from the mobile terminal 100, the distance refers to an average value of a shortest distance and a longest distance between the lighting device 200 and the mobile terminal 100, and the first preset range may be less than or equal to 10 centimeters.
The Hall switch 150 is also called as a Hall digital circuit, works based on the principle of Hall effect, consists of seven parts, such as a reverse voltage protector, a precise voltage regulator, a Hall voltage generator, a differential amplifier, a Schmitt trigger, a temperature compensator, a complementary collector open-circuit output device and the like, has the characteristics of no contact, low power consumption, long service life, high response frequency and the like, is sealed and filled into a whole by epoxy resin inside, and can reliably work in various severe environments.
The hall effect is a phenomenon that when a metal or semiconductor sheet with current is vertically placed in a magnetic field, a potential difference is generated between two ends of the sheet, the potential difference between the two ends is called hall potential U, and the expression is as follows:
U＝KIB/d
in the formula, K is a Hall coefficient, I is current passing through the sheet, B is the magnetic induction intensity of an external magnetic field, and d is the thickness of the sheet. Therefore, the sensitivity of the Hall effect is directly proportional to the magnetic induction intensity of the external magnetic field.
This phenomenon is caused by the fact that carriers in the metal sheet or the semiconductor sheet to which current is applied are deflected and accumulated to both lateral sides of the metal sheet or the semiconductor sheet, respectively, by the lorentz force generated by the magnetic field, thereby forming an electric field called a hall field. The electric field force generated by the Hall electric field is opposite to the Lorentz force, so that the carriers are prevented from being accumulated continuously until the Hall electric field force and the Lorentz force are equal, and a stable voltage is established on two sides of the metal sheet or the semiconductor sheet, namely the Hall voltage.
Specifically, the lighting device 200 includes a first electromagnetic component, which may be an energized component that generates magnetism, such as an electromagnet composed of a core and a coil wound around the outer circumference of the core, or a single magnetic component, such as a common magnet. Based on the principle of the hall effect, when the first electromagnetic component is close to the hall switch 150 of the mobile terminal 100, the first electromagnetic component is used as an external magnetic field, and when the close distance is small enough within a first preset range, the magnetic induction intensity of the external magnetic field is greater than the conduction threshold value of the hall switch 150, the output tube of the hall circuit is conducted, and the hall switch 150 is turned on. Meanwhile, when the display screen 120 of the mobile terminal 100 is bright, the hall switch 150 is turned on and the display screen 120 of the mobile terminal 100 is bright, and the control element 140 controls the illumination device 200 to be turned on; when the first electromagnetic component is far away from the hall switch 150 of the mobile terminal 100 and the distance far away is large enough to be outside the first preset range, the magnetic induction intensity of the external magnetic field is smaller than the conduction threshold of the hall switch 150, the output tube of the hall circuit is cut off, and the hall switch 150 is turned off. At this time, since the hall switch 150 is turned off, the control element 140 does not control the illumination apparatus 200 to be turned on regardless of whether the display state of the display screen 120 of the mobile terminal 100 is on or off.
When the lighting device 200 with the first electromagnetic assembly 210 is close to or far away from the mobile terminal 100 with the hall switch 150, the magnetic induction intensity of the external magnetic field induced by the hall switch 150 is different according to the distance between the lighting device 200 and the mobile terminal 100, and the hall switch 150 can be automatically triggered to be turned on or off, and meanwhile, when the display screen 120 of the mobile terminal 100 is bright, the control element 140 controls the lighting device 200 to be turned on, so that the control process is more intelligent.
Further, the mobile terminal 100 further includes a second electromagnetic component having an electromagnetic polarity opposite to that of the first electromagnetic component, and when the lighting device 200 approaches the mobile terminal 100, the lighting device 200 is fixed with the mobile terminal 100 by a magnetic force between the second electromagnetic component and the first electromagnetic component.
The first electromagnetic component serves as both a trigger condition for the hall switch 150 to be turned on or off and a component for the lighting device 200 and the mobile terminal 100 to generate magnetic force to be fixed.
Different from the prior art, the lighting device 200 and the mobile terminal 100 are fixed through magnetic force, so that the lighting device is more reliable, the design of external fixing parts is reduced, and the influence on the appearance due to overlarge integral volume is avoided.
Further, the mobile terminal 100 further includes a first power supply circuit for supplying power to the lighting device 200 to light the lighting device 200; the control element 140 is used for controlling the first power supply circuit to be turned on or off according to the state of the hall switch 150 and the display state.
In this way, the mobile terminal 100 is utilized to supply power to the lighting device 200, so that the mobile terminal 100 can control the lighting device 200 more intelligently, and meanwhile, the cost can be saved.
Further, the mobile terminal 100 includes a first contact end 160, the lighting device 200 includes a second contact end 210, and the mobile terminal 100 is electrically connected to the lighting device 200 through the first contact end 160 and the second contact end 210, wherein one of the first contact end 160 and the second contact end 210 is a conductive card slot, and the other is a spring-type probe, and when the spring-type probe is clamped in the conductive card slot, the mobile terminal 100 is electrically connected to the lighting device 200.
Specifically, the mobile terminal 100 is electrically connected to the lighting device 200 through the first contact end 160 and the second contact end 210, wherein one of the first contact end 160 and the second contact end 210 is a conductive card slot, and the other is a spring-type probe, and when the spring-type probe is clamped in the conductive card slot, the mobile terminal 100 is electrically connected to the lighting device 200. The first contact end 160 and the second contact end 210 are connected in a matching manner to realize the electrical connection between the mobile terminal 100 and the lighting device 200, and when the first contact end 160 is a conductive card slot, the second contact end 210 is a spring-type probe; when the first contact end 160 is a spring-type probe, the second contact end 210 is a conductive card slot. In order to increase the reliability of the electrical connection, preferably, the first contact end 160 and the second contact end 210 may be a plurality of spring-type probes and conductive card slots, and the number of the spring-type probes and the number of the conductive card slots should be the same, as shown in fig. 2, which is a schematic diagram of the connection between the first contact end 160 and the second contact end 210 provided in this embodiment of the present application, and when the number of the spring-type probes is 5, the number of the corresponding conductive card slots is also 5. The conductive card slot may be one or more metal sheets, and in order to ensure the reliability of the electrical connection, preferably, the conductive card slot is a plurality of recessed metal sheets, the plurality of recessed metal sheets should be identical, and parameters including size, recessed angle, depth and the like should be identical, and the positions of the plurality of recessed metal sheets should be in one-to-one correspondence with the positions of the plurality of spring-type probes, so as to ensure that the conductive card slot is electrically connected with the plurality of spring-type probes respectively. As shown in fig. 3, which is a schematic view of an internal structure of the second contact end provided in the embodiment of the present application, the spring-type probe is formed by riveting and prepressing three basic components, namely, a needle tube 211, a spring 212, and a needle shaft 213, by a precision instrument. The spring 212 is located in an inner structure formed by the needle tube 211 and the needle shaft 213, and can move freely, and the needle shaft 213 can move up and down along the sidewall of the needle tube 211.
In practical application, when the needle shaft 213 is far away from the conductive groove, the needle shaft 213 is located at the farthest end of the needle tube 211, the spring 212 is not compressed or is compressed a small amount, at least one end of the upper end or the lower end of the spring 212 is not in contact with the lower wall of the needle tube 211 or the upper wall of the needle shaft 213, the circuit of the spring type probe is not conducted, and the electrical connection cannot be realized; when the needle shaft 213 is close to the conductive groove and the spring 212 is gradually compressed, and the compression amount of the spring 212 is large enough, the upper end and the lower end of the spring 212 are respectively contacted with the lower wall of the needle tube 211 and the upper wall of the needle shaft 213, and the spring-type probe is conducted with the circuit of the conductive clamping groove to realize electric connection. Preferably, the surface of the spring type probe can be plated with gold, so that the anti-corrosion function, the mechanical property, the electrical property and the like of the spring type probe can be better improved. Preferably, the surface of the spring 212 may also be gold plated to better enhance its conductivity. The needle tip of the needle shaft 213 may be a sharp needle, a grasper needle, a round-nose needle, a knife-type needle, or the like.
Thus, the spring probe type connector is applied to the electrical connection between the mobile terminal 100 and the lighting device 200 as a connector, so that the weight and the volume of the connector can be reduced, and the connector is more delicate and attractive.
In another embodiment of the present application, the lighting device 200 includes a second power supply circuit for supplying power to the lighting device 200 to light the lighting device 200, and the control element 140 is configured to control the second power supply circuit to be turned on or off according to the state of the hall switch 150 and the display state.
When the lighting device 200 is not fixed to the mobile terminal 100, the lighting device 200 is not electrically connected to the mobile terminal 100, and the first power supply circuit of the mobile terminal 100 cannot supply power to the lighting device 200. The lighting device 200 is controlled to be turned on and off by providing the lighting device 200 with a second power supply circuit independent from the first power supply circuit, and at the same time, providing a control switch independent from the control element 140 of the mobile terminal 100. Thus, when the lighting device 200 is not used with the mobile terminal 100, the lighting device 200 can be used as an independent reading lamp without losing the use value because the lighting device cannot be used with the corresponding mobile terminal 100.
Meanwhile, the second power supply circuit further includes another control element 140, and when the lighting device 200 is not fixed to the mobile terminal 100, the control element 140 may control the lighting brightness and the lighting color of the lighting device 200, so as to improve the user experience.
