Abstract

The utility model relates to a flash electric torch which comprises a casing (1), an electric bulb (4) and a reflecting surface (2). The utility model is characterized in that the reflecting surface (2) of the flash electric torch is provided with a plurality of light-emitting diodes (3); the optimum number of the light-emitting diodes (3) which are evenly distributed on the reflecting surface (2) is from 2 to 6; the light-emitting diodes (3) are driven by an oscillation circuit, and are connected in parallel with electric bulbs on both ends of a battery (9). When the light-emitting diodes (3) with definite colors are selected, the flash electric torch can emit high-frequency flash signals with specific colors. The utility model has the advantages of obvious alarm and alarming effect, simple structure and power consumption saving.

Description

Flickering flashlight

The utility model relates to a kind of flashlight, particularly a kind of flickering flashlight.

The flashlight that the alarm signal that can flash is seldom arranged in the market, and when the vehicle failure of user under situations such as night or greasy weather stopped and the emission of open-air distress signal all need to use such flashlight." the flashlight device of flash of light automatically " and ZL89219657.2 " safety torch " of Chinese patent ZL86210450 all disclose a kind of flashlight with flash function, its design is and increases oscillating circuit and with the load of former small electric bulb as oscillating circuit, with the light on and off of small electric bulb as flashing signal; The shortcoming of this scheme is that flashing rate is low, and can't send the stroboscopic warning light of particular color.

The purpose of this utility model provides a kind of flashlight that also can send the flashing signal of setpoint color except small electric bulb sends illumination light with regard to being for the defective that overcomes above-mentioned prior art.

The purpose of this utility model is such realization: based on the common flashlight that comprises housing, small electric bulb and reflecting surface, several light emitting diodes are set on the reflecting surface of flashlight, these diodes are driven by oscillating circuit.

Compared with prior art, select the light emitting diode of certain color, can make flashlight send the high frequency flashing signal of particular color, report to the police, the caution effect is obvious, and simple in structure, power consumptive province.

Description of drawings:

Fig. 1 is a front view of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is circuit theory diagrams of the present utility model.

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing:

As Fig. 1, shown in Figure 2, flickering flashlight is based on a common flashlight, comprise housing (1), small electric bulb (4) and reflecting surface (2), be embedded with a plurality of light emitting diodes (3) on the reflecting surface therein (2), shown in the figure be 3, generally can there be 2～6, preferably evenly distribute as shown in the figure, can certainly increase or arrange by practical situation by definite shape, these light emitting diodes (3) are driven by the oscillating circuit of series connection with it and are connected in parallel on the two ends of battery (9) with small electric bulb (4), and as shown in Figure 3, the A among the figure is oscillating circuit, its concrete composition can adopt existing various oscillating circuit, does not describe in detail.

Be positioned at housing and link to each other with an end of battery (9) with the contacted conducting strip of hand pushing switch (7) (8) afterbody of torch, its head then is positioned between small electric bulb contact (6) and the led lighting circuit trigger (5), thereby constitute a single-pole double-throw switch (SPDT), current pusher is started buck switch (7) contacts conducting strip (8) respectively with led lighting circuit trigger (5) with small electric bulb contact (6), can connect small electric bulb loop and diode circuit respectively and luminous respectively.

Claims

1. flickering flashlight, comprise housing (1), small electric bulb (4) and reflecting surface (2), it is characterized in that on the reflecting surface (2) at flashlight several light emitting diodes (3) being set, these diodes (3) are driven by oscillating circuit and are connected in parallel on the two ends of battery (9) with small electric bulb.

2. flickering flashlight as claimed in claim 1 is characterized in that described light emitting diode (3) is 2～6, is uniformly distributed on the reflecting surface (2).

3. flickering flashlight as claimed in claim 1, it is characterized in that having in the described housing (1) one with the contacted conducting strip (8) of hand pushing switch (7), its afterbody links to each other with an end of battery (9), head then is positioned between small electric bulb contact (6) and the led lighting circuit trigger (5), constitutes a single-pole double-throw switch (SPDT).
