CN2074414U - Wearing-type batteries-saving flash lamp - Google Patents

Abstract

The utility model provides a wearing type energy-saving flash lamp which is used to bring on pedestrians' or drivers' attentions and avoid mutual collision in poor illumination places. The flash lamp is a casket that is two times larger than a matchbox, and the inner part of a translucid cover at the top of the flash lamp is provided with miniature bulbs. A capacitance-resistant self-excitation squitter in the casket produces periodic pulse train whose on-off time ratio is about 1: 5 powered by 2 #5 batteries. The miniature bulbs are then powered on 1/6 the time of a week and emit flashing which has identical lighting intensity as that of an electric torch, and the power is cut off in the remaining pulse resting phase.

Description

Wearing-type batteries-saving flash lamp

It is little and can produce the flasher of enough lights again and again that the utility model relates to a kind of power consumption, on one's body button hangs over oneself when the night walking along the street, can impel messenger or perceiveing of sending a car and avoid bumping against.

In the walking along the street of illumination at night weak point, existing means are to use flashlight lighting, hand-held hold And and will often upgrade battery but flashlight need take one.As for when the night by bike, light car light though can adorn with magneto, additionally increased cyclist's power load.More than two kinds of modes generally be not happy to use by the people so that the accident that bumps against between person to person or people and the car takes place easily.

In order to improve above-mentioned situation, the utility model provides the little as 2 casket matches of a kind of body, light is enough and the very little flasher of power consumption, it can resemble to buckle as the pen and be inserted in coat pocket, hem buttonhole even clothes and wait showy position on the shoulders, as navigation light emission flash of light again and again, impel messenger or perceiveing of sending a car and in time dodge calmly, this walks the crossing or more can reduce or remit the danger of being hit when turning, especially to the sensation decline and action owes flexibly that the elderly and the disabled has increased safety factor.Use in addition flasher AT STATION, the numerous places of the stream of people such as wheel port or airport look for the people or meet the people, show that in order to draw the other side notes certain effect is also arranged.

The utility model is to realize like this, with reference to accompanying drawing 1,2 flashers plastics or metal case (1) are arranged, the self-pushing blocking oscillator (3) (hereinafter to be referred as oscillator) that device is made up of PNP and NPN transistor and resistance and capacitor in the casket, miniature bulb (4), switch (5) and 2 save ##5 dry-cells (6).On 1 plane of case (1) 1 clip (2) is housed, light transmission plastic window or diffuser are inlayed in its position corresponding to miniature bulb (4).When switch (5) pulled logical after, oscillator (3) is that self-excitation produces vibration, the output duration is short and periodic pulse train that stand-down is long relatively, drive miniature bulb (4) the radiation relative frequent flash of light of growing that ignites that time is short and pressing with the fall time, the instantaneous brightness of flash of light is equal to 2 nodal pattern flashlights, but the cycle average current then reduces significantly, thereby has reached the benefit of economize on electricity.This in addition bright conversion that secretly replaces, other people attention of easier triggering.

The cycle strobe of flasher can be selected by situation, and as at 1 second up and down the time, the make-to-break ratio of pulse can reach more than the 1:5, and holocyclic like this average current is 1/6 of full value, and promptly battery power consumption has reduced by 6 times.Flasher is simple in structure, can be under the condition of 0 °～50 ℃ of environment temperatures operate as normal, even if because of battery with old, live forces down when reducing to 2V. in fact, is not less than 20 meters in the perceiveed distance of black dull place color break-up.

Claims (3)

1, a kind of can clip on one's body economize on electricity flasher, be the case (1) of plastics or metal shell, the inside is provided with self-pushing blocking oscillator (3), miniature bulb (4), battery (6) and switch (5), it is characterized in that:

A, described case (1) upper end are printing opacities corresponding to miniature bulb all around.

1 clip is installed on 1 plane of b, described case (1).

C, described self-pushing blocking oscillator (3) produce periodic pulse train and intermittently ignite to order about miniature bulb (4).

2, device according to claim 1 is characterized in that self-pushing blocking oscillator (3) is made up of PNP and NPN transistor and electric capacity and resistor, by 2 joint #5 powered battery.

3, according to claim 1 and 2 described devices, it is characterized in that be set in about in the of 1 second the cycle of oscillation of self-pushing blocking oscillator (3), pulse is not less than 5 times of duration stand-down.
