Detailed description of the invention
In order to make the technical solution of the utility model more clearly show, below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1 to Fig. 5, the utility model provides a kind of wireless charging LED, comprises lamp body 10 and a wireless charging base 80.This lamp body 10 comprises a main part 20, be arranged on the power supply unit 30 of the bottom of this main part 20 and be arranged on the portion that is affiliated to 40 at top of main part 20.Produce magnetic field after described wireless charging base 80 is connected with extraneous power supply, the magnetic field that wireless charging base 80 sends is converted to power supply and powers to main part 20 by described power supply unit 30.
The setting in the form of annular discs of described wireless charging base 80.This wireless charging base 80 comprises lower cover 81, lower cover 82 and is folded in the circuit board 90 of lower cover 81 and lower cover 82.This circuit board 90 comprises external power source and connects module 91, emitter coil 94, protection module 92 and automatic charging module 93.This protection module 92 connects described external power source and connects module 91 and emitter coil 94, by identifying whether the frequency of extraneous close object belongs to the chargeable frequency range of setting, to determine that whether opening emitter coil 94 charges.In the present embodiment, described chargeable frequency range is set as 100kHz ~ 200kHz (international wireless charging QI standard), to avoid metal chargings such as close non-rechargeabel iron plates, causes improper heating to cause dangerous generation.Described automatic charging module 93 connects protection module 92 and emitter coil 94.Whether this automatic charging module 93 reaches the full value (as 4.2V) of setting by the voltage of the power supply unit 30 of lamp body 10 described in emitter coil 94 reverse induction, when the voltage of power supply unit 30 is less than full value, this automatic charging module 93 automatic switching on, thus emitter coil 94 is communicated with external power source produce magnetic field, to power to the power supply unit 30 of lamp body 10; When the voltage of power supply unit 30 is full value, representing lamp body 10 does not need charging, and this automatic charging module 93 disconnects, and avoids the waste occurring electric energy.
This power supply unit 30 is arranged on the bottom of lamp body 10.This power supply unit 30 comprises the control module 33 of receiver coil 31, battery 32, connection receiver coil 31 and battery 32.The frequency of described receiver coil 31 and the frequency match of described emitter coil 94.When lamp body 10 is placed after on wireless charging base 80, when the battery 32 of power supply unit 30 is in non-full power state, wireless charging base 80 starts emitter coil 94 and charges to power supply unit 30.Understandably, wireless charging base 80 of the present utility model have employed QI wireless charging standard, and the product such as mobile phone, the portable power source that only meet the internal or external wireless receiving charging of this standard all charge by wireless charging base 80.
Described main part 20 comprises printing opacity shell 21, the LED circuit board 22 be arranged in printing opacity shell 21, connect second connector 24 at the first connector 23 bottom LED circuit board 22 and connecting circuit board 22 top.Described LED circuit board 22 comprises drive circuit die set 23 and is arranged on some LED25 (not shown) of relative two sides of LED circuit board 22.
Described printing opacity shell 21 is in thin elliptic cylindrical shape, and namely the cross section of printing opacity shell 21 is the elliptical shape of lengthwise, and namely major semiaxis a is much larger than semi-minor axis b (a, b are oval major semiaxis, the conventional symbol of semi-minor axis, and figure does not mark); Particularly, in the present embodiment, all substantially oblong-shaped setting of each several part cross section of described printing opacity shell 21, its radius scale b:a is between 0.6 ~ 0.2.Further, the bottom of described printing opacity shell 21 reduces to top gradually, and the radius scale of bottom cross section is between 0.6 ~ 0.5, the radius scale of the cross section on top is between 0.3 ~ 0.2, and the radius scale of the cross section of other parts is reduced from bottom gradually toward top.By setting like this, the light that LED25 is sent can 360 degree evenly send.The bottom of this printing opacity shell 21 to downward-extension one clamping part 210 to fix with described power supply unit 30; The top of this printing opacity shell 21 upwards extends an extension 215 to be connected and fixed with the described portion 40 that is affiliated to.
The elongated setting of described LED circuit board 22.The LED25 surface on the relative two sides of this LED circuit board 22 is also coated with light guide plate (not shown), carries out dispersed by light guide plate to the light that LED25 sends, the light that main part 20 is sent evenly soft, no dark space.
Described drive circuit die set 23 connects the battery 32 of described power supply unit 30, with the unlatching of control LED25 and light modulation.This drive circuit die set 23 comprises switch 230 and a PWM light modulation module 235.In the present embodiment, described drive circuit die set 23 is arranged on the bottom of LED circuit board 22, and described switch 230 is arranged on the second connector 24 to be connected with LED circuit board 22 and to be affiliated to portion 40 described in passing.During work, when switch 230 is by user's short on time (the present embodiment is short-and-medium is less than or equal to 1 second by for pressing to unclamp), drive circuit die set 23 couples of LED25 supply electric-opening or disconnection; When switch 230 is grown on time (in the present embodiment, length is greater than 1 second by for pressing) by user, the brightness of PWM light modulation module 235 control LED25 drops to minimum brightness value gradually from present intensity, then brightness is increased again gradually to peak, thus circulate between minimum brightness and maximum brightness and gradually change, when user confirms to reach a certain required brightness, trip switch 230, then PWM light modulation module 235 control LED25 is stabilized in current brightness.Further, be the peak and the minimum that allow user can know brightness, automatically glimmer when the brightness of LED25 reaches peak or minimum in cyclic process time, thus person easy to use identifies.Because this drive circuit die set 23 takes PWM light modulation module 235 and constant current to drive, when lamp body 10 be full of uses as emergency light after electricity time, service time is inversely proportional to brightness, and the brightness namely after adjustment is lower, and the time of use is longer.
The described top of being affiliated to portion 40 and connecting main part 20.This middle part of being affiliated to portion 40 is provided with perforation 41, extracts or be hung on the hook of wall for user, very convenient.
The above embodiment only have expressed a kind of embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that 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.
