[embodiment]
With reference to figure 1, the luminous magnifier device that the utility model one embodiment provides, mainly comprise convex lens 100, illuminating lamp 200 and portable power source 300, illuminating lamp 200 is around in the edge of convex lens 100, premised on the visual field not affecting convex lens.
With reference to figure 2, in the present embodiment, luminous magnifier device also has a housing 400, and housing 400 has the convex lens mounting groove 410 that runs through housing two sides, and convex lens 100 are installed on convex lens mounting groove 410, makes the eyeglass two sides of convex lens 100 visible.Illuminating lamp 200 is located in the edge of convex lens 100, and it is inner to be positioned at housing 400.In the present embodiment, illuminating lamp is the LED group of two LED compositions, and be located in the edge of convex lens 100, usual convex lens are circular eyeglass, so two LED are arranged in the two ends of any diameter.LED does not have number to limit, and can form LED group by list LED only or two or more LED and form, for ensureing that illumination is penetrated evenly, LED point-like is evenly distributed on the outward flange of convex lens.The present embodiment adopts two LED series lightings, therefore when it normally works, terminal voltage sum is approximately 6V.And our lithium cell operating voltage is substantially at 2.8V-4.2, so adopt voltage increase and current constant LED circuit.When the quantity of LED is greater than two, principle is the same, and just required voltage is higher.If adopt single LED illumination, need to drive with step-down constant-current LED.No matter be therefore that voltage increase and current constant LED drives or step-down constant-current LED drives, as long as constant current drives the luminous multiplying arrangement that can be used for as the utility model provides to carry out scene illumination.As long as LED is luminous, and be in constant electric current driving, so its luminous intensity would not change along with cell voltage.If do not use constant voltage drive circuit, along with using the voltage of lithium battery to diminish, the forward conduction voltage several of single LEDs is invariable, when cell voltage is near or below the forward voltage of LED, LED can be obviously dimmed or do not work, and can have a strong impact on illuminating effect.Portable power source 300 comprises switch 310, lithium cell 320, charging inlet 330, electric discharge interface 340, constant current driver circuit for LED 350 and LED light.Housing 400 outside surface is located at by switch 310, and provide electric energy for controlling portable power source start/stop for illuminating lamp 200, this switch is normal open switch, presses switch and starts illumination, trip switch lighting-off.Lithium cell 320 commonly uses battery for portable power source, also can use.Charging inlet 330 and electric discharge interface 340 are connected to housing 400 outside surface, and charging inlet 330 charges for portable power source 300 for using external charger, computing machine etc.; Electric discharge interface 340 is also its charging for connecting the external mobile device such as mobile phone.LED light is used to indicate portable power source charge/discharge state, and specifically, LED light comprises 4 LED bulb, and when portable power source 300 is in the charging stage, 4 LED bulb are lighted from left to right successively along with being full of of electricity; When portable power source 300 is in discharge regime, along with the minimizing gradually of portable power source 300 self electric quantity, 4 LED bulb are extinguished to show charging and discharging state from right to left successively.
With reference to figure 3-Fig. 4, the schematic diagram that portable power source 300 in the luminous magnifier device that the present embodiment provides charges, discharge as shown in Figure 4, external power supply is that lithium cell 320 charges by MICRO charging inlet, lithium cell can be not only that illuminating lamp 200 is powered by constant current driver circuit for LED, can also be the external mobile equipment charges such as mobile phone by the USB interface that discharges, do not have the problems such as electricity to solve mobile phone, serve as common portable power source and use.Meanwhile, lithium cell is that the LED light being used to indicate portable power source 300 charge/discharge state is powered.Why will design constant current driver circuit for LED is because LED is the low voltage drive lied prostrate by 2-3, directly can not connect the alternating current of 220V.With reference to figure 4-Fig. 5, employ this monolithic voltage boosting dc/direct current transducer of FS1725 in the utility model, to complete the object that constant current drives, this chip commercially can find at present.FS1725 is LED drive IC, is widely used in LED-backlit illumination.FS1725 adopts BOOST topology, and no matter control mode, to obtain for the purpose of constant output current, inputs cell voltage and how to change, and the electric current in LED remains invariable all the time, and the luminous intensity of such LED is just constant.
The luminous magnifier device that second embodiment of the present utility model provides, be with the difference of the first embodiment, illuminating lamp 200 is detachably connected to convex lens 100, and when removing illuminating lamp 200, convex lens 100 can be used as common magnifying glass and use.Same, portable power source 300 is detachably connected to illuminating lamp 200, and illuminating lamp can combine separately with portable power source 300 and be used as lighting device, meets the various needs of researchist, field study personnel.
The luminous magnifier device that 3rd embodiment of the present utility model provides, be with the difference of the first embodiment, illuminating lamp is incandescent lamp, in the present embodiment, no longer need constant current driver circuit for LED, directly make incandescent lamp be connected to the lithium cell 320 of portable power source 300.
For the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
