Description
Technical field
What a kind of portable rechargeable torch of the utility model related to is a kind of torch light, especially a kind of portable rechargeable torch with overlength lighting hours.
Background technology
Chargeable torch, whether in life at home or in outdoors, all uses extensively. In the prior art, also disclose some chargeable torch, but in the prior art, two key propertys (portability and lighting hours length) of chargeable torch are difficult to simultaneously exhibits excellent, because portable and long lighting hours is inherently one to contradiction. The torch with long lighting hours usually heavy, inconvenience carry, the usual lighting hours of portable torch is also short.
Practical novel content
The purpose of this utility model provides a kind of portable rechargeable torch for above-mentioned weak point, it it is a kind of portable rechargeable torch with overlength lighting hours, by the arrangement of the circuit and electronic component of optimizing chargeable torch and connection, make torch not only portable but also have very long lighting hours.
The utility model takes following technical scheme to realize:
A kind of portable rechargeable torch comprises housing, switchboard it is provided with in housing, LED group is equipped with in one end of housing, the outside of housing is provided with USB and switch, switchboard is equipped with pilot circuit, described pilot circuit comprises rechargeable battery, charging chip and resistance, and rechargeable battery is connected with USB by charging chip, and electric energy sends rechargeable battery to by charging chip; It is connected with resistance between LED group and rechargeable battery; Also being connected with switch between LED group and rechargeable battery, switch is used for controlling the Kai Heguan of LED group.
Described rechargeable battery adopts lithium cell.
Described LED group is formed in parallel by multiple LED.
Housing is also provided with pilot lamp, is used for showing charging chip charging state; After being switched on power by USB, the pilot lamp on charging chip is bright, and pilot lamp is that green expression charging chip electricity is full, when pilot lamp is red, represents charging chip electricity underfill.
When switch closes, the series circuit of rechargeable battery, resistance and LED group composition is switched on, and LED is luminous;When switch disconnects, the series circuit of rechargeable battery, resistance and LED group composition disconnects, and LED does not work.
More reasonable for making enclosure interior space utilize, described USB and switch lay respectively at housing offside.
The utility model is reasonable in design, structure is simple, small and exquisite portable, USB, charging chip and rechargeable battery form charging circuit, plug power supply by USB, so that it may to realize the charging to rechargeable battery; Rechargeable battery, resistance, LED group and switch constitute discharging circuit, and close switch, so that it may to realize illumination; Owing to have employed LED group, illuminate better effects if, energy-conserving and environment-protective, maximise efficiency of energy utilization; Owing to adopting charging chip and rechargeable battery, can accumulation of energy better, and the lighting hours making this torch is longer, removes the trouble of user's frequent charge from.
Accompanying drawing explanation
Below with reference to accompanying drawing, the utility model is described in further detail:
Fig. 1 is the pilot circuit principle schematic of the utility model portable rechargeable torch.
In figure: L, LED group, R, resistance, USB, USB, CDXP, charging chip, K, switch, LDC, rechargeable battery.
Embodiment
With reference to accompanying drawing 1, a kind of portable rechargeable torch comprises housing, switchboard it is provided with in housing, LED group L is equipped with in one end of housing, the outside of housing is provided with USB USB and K switch, and pilot circuit is housed on switchboard, and described pilot circuit comprises rechargeable battery LDC, charging chip CDXP and resistance R, rechargeable battery LDC is connected with USB USB by charging chip CDXP, and electric energy sends rechargeable battery LDC to by charging chip CDXP; Resistance R it is connected with between LED group L and rechargeable battery LDC; Also being connected with K switch between LED group L and rechargeable battery LDC, K switch is used for controlling the Kai Heguan of LED group L.
Housing is provided with pilot lamp, is used for showing charging chip CDXP charging state, after being switched on power by USB USB, pilot lamp is bright, pilot lamp is that green expression charging chip CDXP electricity is full, when pilot lamp is red, represents charging chip CDXP electricity underfill.
K switch is used for controlling the Kai Heguan of LED group LED, and when K switch is closed, the series circuit that rechargeable battery LDC, resistance R and LED group L form is switched on, and LED group L is luminous; When K switch disconnects, the series circuit that rechargeable battery LDC, resistance R and LED group L form disconnects, and LED group L does not work.
