The utility model has the advantages that, reduce the volume of flashlight by a wide margin, reach real pocket standard, save the electric energy, do not generate heat and longe-lived.

Description

Power saving high brightness pocket torch

The battery that the utility model relates to a kind of power saving high brightness pocket torch, particularly a kind of available low voltage is lighted the high-brightness LED of high voltage, to produce the pocket torch of high brightness and power saving.

Traditional pocket torch, it is broadly divided into and uses two kinds of conventional bulb formula and LED formulas, and its feature and shortcoming are as follows:

1, conventional bulb formula (as shown in Figure 5); Tradition pocket torch (6) is big because of conventional bulb (61) tool power consumption, and the low characteristic of efficient, therefore, at least need to use two or two the joint above batteries (62) light its bulb (61), can reach general brightness of illumination, but this kind adopts the pocket torch (6) of conventional bulb (61), and it is big because of power consumption, and shortened the service time of battery (62); And must change battery often, cause and use inconvenience, and because of battery (62) quantity can't reduce, and making its volume still can't reach pocket standard, temperature height when using because of conventional bulb (61) in addition needs often more to change the bulb (61).

2, LED formula; Use the next light source as flashlight of LED, use conventional bulb power consumption to reach inefficient problem greatly though effectively solve, in the time of need lighting the LED of high voltage, therefore then essential at least two batteries of using, also can't effectively dwindle the flashlight volume.

The purpose of this utility model provides a kind of power saving high brightness pocket torch.

The purpose of this utility model is to realize like this, a kind of power saving high brightness pocket torch, comprise members such as flashlight body, oscillation step-up circuit, high-brightness LED, battery, rear end swivelling cover and preceding snoot, it is characterized in that: at flashlight body front end, be provided with an oscillation step-up circuit, a high-brightness LED be connected in the power output end of this oscillation step-up circuit; After battery is inserted the flashlight body, make battery wherein an end contact with a wherein power supply contact of oscillation step-up circuit, another power supply contact of oscillation step-up circuit then connects and extends to the rear end of flashlight body by a conductiving metal strip, the rear end of flashlight body is provided with the auspicious swivelling cover in a back, be provided with the spring that contacts with battery in it, the auspicious preceding snoot that is provided with before the flashlight body; Rotation rear end swivelling cover, conductiving metal strip is contacted and energized with the spring that is contacted with another utmost point of battery, promote the voltage of battery by oscillation step-up circuit, make the voltage after the lifting light the high-brightness LED that needs high voltage, and then realize using single battery to light the LED of high-tension high brightness.

The utility model advantage is by oscillation step-up circuit, and effectively the voltage with battery is promoted to a specific voltage, lights high-tension high-brightness LED, thereby significantly promotes brightness; In addition, utility model can use single battery to light high-tension high-brightness LED by oscillation step-up circuit, has power saving, saves money and reduces waste battery quantity number and then reduce environmental pollution; In addition, owing to can use the single battery illumination, thus significantly dwindled the volume of flashlight, and then be convenient to carrying of this flashlight.

Below in conjunction with accompanying drawing the utility model is elaborated, so that further understand architectural feature of the present utility model and effect thereof.

Fig. 1 is a three-dimensional exploded view of the present utility model.

Fig. 2 is a combination dissected figure of the present utility model.

Fig. 3 enumerates the employed oscillation step-up circuit figure of wherein a kind of the utility model.

Fig. 4 is the enforcement illustration that the utility model is applied to a kind of wear-type illuminating lamp.

Fig. 5 is the combination dissected figure of traditional pocket torch.

Each label is respectively among the figure:

1 high-brightness LED; 2 oscillation step-up circuits; 21 conductiving metal strips; 22 power supply contacts; 23 switches; 3,52,62 batteries; 4 flashlight bodies; 41 snoots; 42 rear end swivelling covers; 5 wear-type illuminating lamps; 51 box bodys; 53 coiled pipes; 6 flashlights.

See also Fig. 1, Fig. 3 and Fig. 3.The utility model is to use the battery 3 of low voltage to light the high-brightness LED 1 of high voltage, to produce the pocket torch of high brightness and power saving.Mainly be at flashlight body 4 front ends, be provided with an oscillation step-up circuit 2, and a high-brightness LED 1 is connected in the power output end of this oscillation step-up circuit (2), and after making battery 3 insert flashlight body 4, make wherein auspiciously contacting of battery 3 with a wherein power supply contact 22 of oscillation step-up circuit 2, another power supply contact of oscillation step-up circuit (2) then connects by a conductiving metal strip 21 and extends to the back auspicious of flashlight body 4, rotation rear end swivelling cover 42 makes conductiving metal strip 21 contact and energized with the spring 421 that is contacted with battery 3 another utmost points; Promote the voltage of battery 3 by oscillation step-up circuit 2, and make the voltage after the lifting can light the high-brightness LED 1 that needs high voltage, and then realize using single (joint) battery 3 can light the purpose of high-tension high-brightness LED 1, and focus on brightness significantly to promote by mat flashlight body 4 set preceding snoots 41.

See also Fig. 4 again, it is the embodiment that the utility model is applied to a wear-type illuminating lamp 5.In the side box body 51, be provided with oscillation step-up circuit 2 therein, battery 52 arranged and be provided with a switch 23 in a side device, with control power supply unlatching or close; In box body 51 1 sides, group is provided with a coiled pipe 53, and in the end of this coiled pipe 53, is provided with a high brightness 1ED1 who is connected with oscillation step-up circuit 2, thereby reaches the purpose of power saving and high efficiency illumination.

In sum, the utlity model has and significantly to dwindle the flashlight volume, reach real pocket mark Standard, and keep power saving, do not generate heat and advantage that the life-span is long.
