The present invention is related to a magnetic induction rechargeable lamp device resembling a candle.
Smoke of the conventional candle is filled with carbon dioxide to foul the air; normally a conventional candlelight is flickered by a gust of wind. To improve this defect, persons skilled in the art have provided electronic candle such as TWM 216,183 entitled “Outdoor Electronic Candle” assigned to Wang, Ker-Kwang on Nov. 11, 1993, in which, Wang taught an electronic “fume” with high brightness, which is suitable for an outdoor lighting system. Or as TWM 240,516 entitled “Structure of Electronic Candle” assigned to Jenesis International Inc. on Aug. 11, 2004, in which, an electronic “fume” can be flickered under oscillation of 2˜3 frequencies. And a photosensitive switch on the printed circuit board can activate light emitting diode (hereinafter abbreviated as LED) in surrounding darkness. Or as U.S. Pat. No. 6,479,965 entitled “Auto-illuminating Rechargeable Lamp System” assigned to Barbel et al. on Nov. 12, 2002, in which, Barbel taught a lamp can be rechargeable by magnetic induction, even the lamp removed from the recharging platter could illuminate, the lamp system turned on automatically during power failure.
According to those two TWM216, 183 and TWM240,516, an electronic candle “fume” with high brightness was not equipped with rechargeable battery pack, therefore, when used a longer while, the consumed-up batteries had been replaced. Or a set of rechargeable batteries was required to take out to charge.
However, the battery pack (120) depicted in
Accordingly, the present invention is aimed to provide a magnetic induction charged lamp device. This lamp device includes an electronic candle (hereinafter abbreviated as candle) and a holder, and they are combined in an up and down relationship. Only the holder is positioned into a charger, the candle and the holder combined as a whole can be charged at the same time. After charging, the candle can be separated from the holder. Either candle or holder can emit light in each one's IC processed specific mode. More than one charger can be connected in-line to the same alternate current (hereinafter abbreviated as AC) outlet, and these chargers are to charge different primary and secondary luminaries at the same time.
Point against aforesaid defects, the present invention is aimed to provide a magnetic induction charged lamp device, comprising: a candle includes a housing having diffuser resembling fume, and a second luminary mounted inside the housing; said luminary includes an upstanding printed circuit board (hereinafter abbreviated as PCB), and a light emitting diode (LED) installed to the PCB, a set of rechargeable batteries, a linking terminal, said LED located above the PCB, said terminal exposed below the PCB;
A holder having a base pervious to light, the base being divided into an upper and a lower chambers, a luminary mounted inside the lower chamber, a lid for covering the opening at the bottom end of the lower chamber; said luminary includes a horizontal PCB, a LED installed to the surface of the PCB, a set of rechargeable batteries, a linking terminal, and an electromagnetic coil; said terminal located above the PCB and exposed to the upper chamber, thereby said terminal connected to the terminal of the candle, an electromagnetic coil located below the PCB;
A charger includes a housing, a horizontal PCB mounted inside the housing, and a bottom-lid; said PCB having an electromagnetic coil relative to an electromagnetic coil of the holder, and an outlet for receiving a plug, said outlet exposed outside the housing.
Said luminary of the candle includes IC processing the light emitting modes of LED.
Said luminary of the holder includes IC processing the light emitting modes of LED.
Said PCB of the candle includes a switch exposed outside the housing to switch the power source.
Said PCB of the holder includes a switch exposed outside the bottom lid to switch the power source.
Said charger includes a sheath type plug to connect to a socket of other charger.
Said sheath type plug includes a pressed button exposed outside the housing to determine whether the plug is to pop out or not.
After combination of the candle and the holder, place the holder onto the charger, the rechargeable batteries of the candle and the holder can be recharging by magnetic induction, which is produced between the electromagnetic coils inside the charger and the holder. (According to the Farady's Law)
Both of the candle and the holder are portable emitting light devices, when the holder is detached from the candle, each of them can emit light respectively, or they can emit light altogether.
Both of the candle and the holder actuated by a switch respectively determine whether emitting light or not. LED mounted inside the candle or holder is to emit light by programmable IC with specified modes. Charger is equipped with a sheath type plug and a socket, more than one charger, in turn, can be connected to one another by plugging. Only one AC socket is sufficient for many chargers to charge both of primary and secondary luminaries at the same time.

When said housing 31 is equipped with two electromagnetic coils, two holders will be charged by these two coils. Correspondingly, more electromagnetic coils can electrify more holders at the same time. To facilitate the holder 2 can be placed onto the charger 3 stably, and the electromagnetic coil 321 aligned and relative to the electromagnetic coil 227 in an up and down relationship respectively, a load bearing groove 312 is formed on the top surface of the housing 31 for receiving the holder 2, and the electromagnetic coils 321, 227 can be in vertical alignment with each other.
Moreover, the socket 323 at a first end of the charger 3 is designed to receive a female plug 324a of the conventional AC power line, while a male plug 324b at a second end can plug into a conventional power socket. The socket 323 is also designed to receive sheath type plugs 322 of other charger, said sheath type plug 322 has a button 325 exposed outside the hole 313 of the housing 31, by pressing the button 325 can determine whether the sheath type plug 322 to pop out or not. In other words, after pressing the button 325, the sheath type plug 322 is flexibly extended outside the hole 311 of the housing. Otherwise, by pushing the button 325 in the reverse direction, the sheath type plug 322 can be retracted inside the hole 311 to avoid frictions with something abutted against the sheath type plug.
As shown in
Besides, a sheath type plug 322 exposed outside a first end of the charger 3 is applied to plug into a socket 323 of a second end of the second charger 3′. In turn, the second charger 3′ can plug into the third charger 3″. Thereby, the chargers can be connected one by one in series. The charging capacity can be expanded instead of chargers entangled with the power lines to connect directly to many conventional sockets in one to one respectively, but the sockets are destined not sufficient for the accommodate the charging demands.
When charging, the candle 1 and the holder 2 are not to emit light. For a preemptive warning that the candle 1 and the holder 2 is to re-charge fully, LEDs 123, 223 can emit different color light to show the capacity of the charger.
In practice, the process can be scheduled as following: candle 1 and holder 2 charged with full capacity, after charging, they can be removed from the charger. Each of the candle or holder has a switch exposed outside; the switch can be manually actuated to turn the candle or holder on or off. Therefore, power drain or consumption of the power can be prevented from happened to the users. Or the candle 1 and the holder 2 can emit light together. Or a conventional candle (not shown) can be burned on top of the holder. Moreover, a whole color LED can be adopted as the LED 123 of the candle 1, variant color light can be shown. LED 223 of the holder 2 includes a plurality of conventional LEDs to achieve a time control flickering, or intermittently flickering, or remained bright.
