Utility model content

The purpose of this utility model is just in order to overcome above-mentioned defect, has provided a kind of flashable, energy-saving headlight that can fix.

The energy-saving headlight of the present utility model comprises a sealed casing with a battery inside and a connecting fastener outside, and a waterproof main cover and a transparent lens of a waterproof lamp cap. There are multiple light bulbs in the waterproof lamp cap, and the sealed casing A circuit for controlling the current on and off of the plurality of bulbs is arranged in the body, and the circuit includes: a pulse signal generating circuit, a bulb current on and off control circuit, and a bulb circuit.

The input end of the pulse signal generating circuit is connected to the power supply, and the output end sends out continuous pulse signals at a certain frequency;

The input terminal of the bulb current on-off control circuit receives the pulse signal sent by the output terminal of the pulse signal generating circuit. When the pulse signal is at a low level, the bulb current on-off control circuit makes the bulb current in the bulb circuit conduct; When the signal is at a high level or has no level output, the bulb current on-off control circuit cuts off the bulb current in the bulb circuit;

The pulse signal generating circuit has a control switch, which is used as a control part of the pulse signal generating circuit. The control switch can make the output end of the pulse signal generating circuit continuously send pulse signals, so that the bulb current can be switched on and off. Control the on-off of the bulb current at the rate of the pulse frequency to make the bulb flash; the control switch can also make the output terminal of the pulse signal generating circuit send a low-level signal, so that the bulb current on-off control circuit controls the bulb current to last The control switch can also make the output terminal of the pulse signal generating circuit have no level signal output, so that the bulb current on-off control circuit controls the bulb current to continue to cut off, so that the bulb is extinguished.

The headlight with the above circuit structure can make the headlight have two working states of flashing and constant light by switching the control switch, and the sealed casing loaded with connecting fasteners can be fixed and used by the bracket system or the headband system. The whole product is small and light, easy to carry.
