Miniature flashlight made of high-brightness light-emitting diode

Abstract

The invention discloses a miniature flashlight made of a high-brightness light-emitting diode. The miniature flashlight comprises a power supply, a power switch, a resistor and a light-emitting diode.A positive electrode of the power supply is connected to one end of the power switch through a wire, and the other end of the power switch is connected to one end of the resistor. The other end of the resistor is connected to an anode of the light emitting diode through a wire, and a cathode of the light emitting diode is connected to a negative electrode of the power supply through a wire. The light emitting diode is internally provided with an anode holder, and one end of the anode holder is provided with a pin which is provided with a first soldering point and a second soldering point. Since two soldering points are arranged on the pin, two or more wires can be conveniently welded at the same time, the middle parts of the soldering points are round holes, the wires directly pass the round holes and are welded during welding, and so that the welding is more convenient and firm.

Description

technical field [0001] The invention relates to the technical field of light-emitting diodes, in particular to a miniature flashlight made of high-brightness light-emitting diodes. Background technique [0002] Light-emitting diode is a kind of semiconductor diode, which can convert electrical energy into light energy. Like ordinary diodes, light-emitting diodes are composed of a PN junction and have unidirectional conductivity. When the chemical materials in the light-emitting diode chip are different, they will emit light. Different lights, light-emitting diodes can be used in lighting, advertising lights, indicator lights, screens and other fields. [0003] There are many kinds of existing light-emitting diodes, but the existing light-emitting diodes have some shortcomings. The light-emitting diodes are the same as incandescent lamps. When electric energy is converted into light energy, part of the electric energy is converted into heat energy. Light-emitting light sourc...

Problems solved by technology

[0003] There are many kinds of existing light-emitting diodes, but the existing light-emitting diodes have some shortcomings. The light-emitting diodes are the same as incandescent lamps. When electric energy is converted into light energy, part of the electric energy is converted into heat energy. Light-emitting light source, so the heat generated by it is concentrated in a small area and cannot be dissipated in time, and because the volume of the light-emitting diode is relatively small, it is difficult to weld the light-emitting diode and the wire
