From the time when there was no light bulb before, the sunrise, the life of sunset, and now the more beautiful night life, the light bulb. It can be said to have subverted human society; common lighting equipment includes light bulbs and incandescent light bulbs. Among them, the light bulb uses the electrical conduction of the filament to generate light, and the light of the light bulb is borrowed from the tube The gas is subject to voltage, causing its electrons to collide at high speed to generate ultraviolet rays, which then emit light through the fluorescent powder on the glass tube wall. In these lighting equipment, whether it is a fluorescent tube or a light bulb, it often generates high heat when it emits light, especially in a light bulb. When the high heat generated for a long time cannot be effectively dissipated, the light bulb or lamp is caused. The luminous efficiency of the tube is reduced, and the light bulb tube starts to flicker, and even cannot be lit. On the other hand, the accumulated heat generated by the light bulb for a long time will also cause the aging and corrosion of the lighting equipment circuit and the equipment casing. Therefore, how to propose a novel solution to the problems occurred during the operation of the bulb or tube of the conventional lighting equipment, and design a lighting device with a simple structure that can achieve high brightness and low power consumption, has been eager for users for a long time. Looking forward to the difficulties that the present invention intends to solve, the inventor is based on many years of practical experience in relevant research, development and sales
