Referring to fig. 1 to 3, as shown in fig. 1, a schematic structure of an illumination device fixed on a mobile terminal according to an embodiment of the present application is shown, the mobile terminal 100 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, wherein the detection element 130 is used for detecting a display state of the display screen 120, the hall switch 150 is used for turning on and off according to a distance between the illumination device 200 and the mobile terminal 100, and the control element 140 is used for controlling the illumination device 200 to turn on and off according to the state and the display state of the hall switch 150.
In the embodiment of the present application, the hall switch 150 is similar to a proximity switch, and is automatically triggered to be turned on or off according to the distance between two objects. The display states of the display 120 of the mobile terminal 100 include a bright screen and a dead screen, and when the user is using the mobile terminal, the display state of the display 120 is bright and when the user is not using the mobile terminal, the display state of the display 120 is dead screen. The control element 140 is an element that can calculate and execute instructions according to a set program or logical relationship or the like.
In the actual application process, when the lighting device 200 approaches to the mobile terminal 100, the hall switch 150 is triggered to be turned on, and at the same time, when the display screen 120 is turned on, the control element 140 turns on the hall switch 150 and the display state of the display screen 120 is turned on to control the lighting device 200 to be turned on; when the lighting device 200 is far away from the mobile terminal 100, the hall switch 150 is triggered to be turned 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.
In this way, the lighting device 200 is automatically controlled to be turned on or off by the mobile terminal 100, so that the control is more intelligent, and at the same time, when the hall switch 150 is turned on and the display state of the display screen 120 is turned on, the mobile terminal 100 automatically controls the lighting device 200 to be turned on, so that the problem that the lighting device 200 is still turned on and resource waste is caused when the user does not use the mobile terminal is avoided.
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 between the lighting device 200 and the mobile terminal 100, and the distance refers to an average value of a shortest distance between the lighting device 200 and the mobile terminal 100 and a longest distance, and the first preset range may be 10 cm or less.
The hall switch 150 is also called as a hall digital circuit, works based on the principle of hall effect, is composed of seven parts including a reverse voltage protector, a precise voltage regulator, a hall voltage generator, a differential amplifier, a schmitt trigger, a temperature compensator and a complementary collector open-circuit output device, has the characteristics of no contact, low power consumption, long service life, high response frequency and the like, is integrated by sealing and filling epoxy resin, 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 at two ends of the sheet, and the potential difference at two ends is called a hall potential U, and the expression is:
U＝KIB/d
wherein K is Hall coefficient, I is current passing through the sheet, B is magnetic induction intensity of the externally applied magnetic field, and d is thickness of the sheet. It can be seen that the sensitivity of the hall effect is proportional to the magnetic induction of the externally applied magnetic field.
The reason for this phenomenon is 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, which is called a hall field. The electric field force generated by the hall electric field is opposite to the lorentz force, and prevents carriers from continuously accumulating 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 assembly that is energized to generate magnetism, such as an electromagnet that is formed by a core and a coil wound around an outer ring of the core, or may be a separate magnetic component, such as a conventional magnet. Based on the principle of the hall effect, when the first electromagnetic component approaches the hall switch 150 of the mobile terminal 100, the first electromagnetic component acts as an external magnetic field, and when the distance of approach is small enough within a first preset range, the magnetic induction intensity of the external magnetic field is larger than the conduction threshold 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 120 of the mobile terminal 100 is on, the hall switch 150 is turned on and the display 120 of the mobile terminal 100 is on, and the control element 140 controls the lighting device 200 to be on; when the first electromagnetic component is far away from the hall switch 150 of the mobile terminal 100, and the distance is large enough to be out of the first preset range, the magnetic induction intensity of the external magnetic field is smaller than the on threshold of the hall switch 150, the output tube of the hall circuit is cut off, and the hall switch 150 is closed. At this time, since the hall switch 150 is turned off, the control element 140 does not control the lighting device 200 to be lighted 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 from the mobile terminal 100 with the hall switch 150, the opening or closing of the hall switch 150 can be automatically triggered according to the difference of the distance between the lighting device 200 and the mobile terminal 100 and the difference of the magnetic induction intensity of the external magnetic field induced by the hall switch 150, and meanwhile, when the display screen 120 of the mobile terminal 100 is on, the control element 140 controls the lighting device 200 to be on, so that the control process is more intelligent.
Further, the mobile terminal 100 further includes a second electromagnetic part having an electromagnetic polarity opposite to that of the first electromagnetic part, and the lighting device 200 is fixed to the mobile terminal 100 by a magnetic force between the second electromagnetic part and the first electromagnetic part when the lighting device 200 is close to the mobile terminal 100.
The first electromagnetic component is used as a trigger condition for opening or closing the hall switch 150 and is used as a component for fixing the lighting device 200 and the mobile terminal 100 by generating magnetic force.
Compared with the prior art, the embodiment of the application fixes the lighting equipment 200 and the mobile terminal 100 by magnetic force, is more firm, reduces the design of external fixing parts, and avoids the influence on the appearance caused by overlarge whole volume.
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 configured to control on or off of the first power supply circuit according to the state of the hall switch 150 and the display state.
In this way, the lighting device 200 is powered by the mobile terminal 100, so that the mobile terminal 100 can control the lighting device 200, thereby making the control more intelligent and saving the cost.
Further, the mobile terminal 100 includes a first contact end 160, the lighting device 200 includes a second contact end 210, 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 probe, and when the spring 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, where one of the first contact end 160 and the second contact end 210 is a conductive card slot, and the other is a spring probe, and when the spring 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 clamping groove, the second contact end 210 is a spring type probe; when the first contact end 160 is a spring probe, the second contact end 210 is a conductive card slot. In order to increase the reliability of the electrical connection, it is preferable that the first contact end 160 and the second contact end 210 are a plurality of spring probes and conductive slots, and the number of the spring probes and the number of the conductive slots should be identical, 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 the embodiment of the present application, when the number of the spring probes is 5, the corresponding number of the conductive slots is also 5. The conductive card slot may be one or more metal sheets, and in order to ensure the reliability of electrical connection, preferably, the conductive card slot is a plurality of concave metal sheets, the plurality of concave metal sheets should be identical, including parameters such as size, angle and depth of the concave should be identical, and the positions of the plurality of concave metal sheets should correspond to the positions of the plurality of spring probes one by one, so as to ensure the respective electrical connection with the plurality of spring probes. As shown in fig. 3, the second contact end according to the embodiment of the present application is schematically shown in the internal structure, and the spring-type probe is formed by riveting three basic components of the needle tube 211, the spring 212, and the needle shaft 213 by a precision instrument. Wherein the spring 212 is located in an inner structure formed by the needle tube 211 and the needle shaft 213, and is freely movable, and at the same time, the needle shaft 213 is movable up and down in a direction along a sidewall of the needle tube 211.
In the practical application process, when the needle shaft 213 is far away from the conductive groove, the needle shaft 213 is positioned at the most distal end of the needle tube 211, the spring 212 is not compressed or is compressed by a small amount, at least one of the upper end or the lower end of the spring 212 is not contacted with the lower wall of the needle tube 211 or the upper wall of the needle shaft 213, the circuit of the spring probe is not conducted, and the electrical connection cannot be realized; when the needle shaft 213 approaches the conductive groove and the spring 212 is gradually compressed, 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 when the compression amount of the spring 212 is large enough, 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 probe may be gold-plated, which may better improve its corrosion protection function, mechanical properties, electrical properties, etc. Preferably, the surface of the spring 212 is also gold plated to better enhance its electrical conductivity. The tip of the needle shaft 213 may be a sharp needle, a grasping needle, a round-head needle, a knife-type needle, or the like.
Thus, the spring probe 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 appearance 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 illuminate the lighting device 200, and the control element 140 is configured to control on or off of the second power supply circuit 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 a second power supply circuit independent of the first power supply circuit at the lighting device 200, and at the same time, providing a control switch independent of the control element 140 of the mobile terminal 100. Thus, when the illumination device 200 is not used with the mobile terminal 100, the illumination device 200 can be used as a separate reading lamp, and the use value is not lost because the illumination device is not used with the corresponding mobile terminal 100.
