Abstract

The invention discloses a boosted type LED flashlight provided with one battery. The boosted type LED flashlight is characterized by comprising a 1.5 V battery, a complementary type multivibrator circuit, an oscillation frequency regulating circuit, a boosted circuit, a rectification filtering circuit and an LED loop, wherein the complementary type multivibrator circuit and the oscillation frequency regulating circuit comprise NPN type audions VT1, NPN type audions VT2, high-frequency transformer primary windings L1, potentiometers RP, resistors R1 and capacitors C1; the boosted circuit and the rectification filtering circuit comprise high-frequency transformer secondary windings L2, Schottky diodes D1 and electrolytic capacitors C2; and the LED loop comprises four LEDs, namely, an LED 1, an LED2, an LED3 and an LED4. The boost type LED flashlight overcomes the defects that a conventional incandescent flashlight provided with two batteries is large in power consumption and low in luminance, is a novel light source, and has the characteristics of high luminous efficiency, energy conservation, environment protection, practicality and the like.

Description

technical field [0001] The invention belongs to the technical field of electronics and direct current inverter, and relates to a one-cell battery boosting type light-emitting diode flashlight. Background technique [0002] The traditional two-cell incandescent flashlight generally has a working current of ≥240mA, while the working current of a flashlight made of light-emitting diodes is about 60-80mA. The power consumed by an ordinary incandescent flashlight is about 6 times the power of an LED flashlight. The brightness is also far inferior to LED flashlights. [0003] In order to overcome the defects of large power consumption and low brightness of the traditional two-cell incandescent flashlight, the present invention can light up four ultra-high-brightness white light-emitting diodes with only one 1.5V battery, which is very suitable for home, Night lighting for camping, traveling, etc. The one-cell boosted LED flashlight of the invention is a new type of light source,...
