Miniature flashlight fabricated from high-brightness light-emitting diode

Abstract

The invention discloses a miniature flashlight fabricated from a high-brightness light-emitting diode. The miniature flashlight comprises a power supply, a power switch, a resistor and the light-emitting diode, wherein a positive electrode of the power supply is connected with one end of the power switch via a wire, the other end of the power switch is connected with one end of the resistor via the wire, the other end of the resistor is connected with a positive electrode of the light-emitting diode via a wire, a negative electrode of the light-emitting diode is connected with a negative electrode of the power supply via a wire, a positive electrode support is arranged in the light-emitting diode, a pin is arranged at one end of the positive electrode support, and a first welding point anda second welding point are arranged on the pin. The two welding points are arranged on the pin, and thus, two or more wires can be more conveniently and simultaneously welded; and round holes are formed in middle parts of the welding points, the wires can directly penetrate through the round holes for welding when the wires are welded, and 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
