Background technique

Generally speaking, bulbs used as indoor lighting or signal devices for light (such as: traffic lights, aircraft guidance lights) are used by converting electrical energy into light energy. Initially, incandescent bulbs using tungsten filaments were used. Such incandescent bulbs Although the production cost of the light bulb is relatively low, because the power source used converts more energy into heat than light source, the life of the light bulb is short, and there is a big problem in the use of energy.

Although, recently, in order to solve the problem that the tungsten filament bulb has a short life, an SMPS (switching switch) that converts alternating current (AC) power supplied from the outside into direct current (DC) power and uses the DC power supply as a driving power source has been developed. Type power supply, SwichModePowerSupply) fluorescent lamps and three-wavelength lamps, although compared with bulbs, they convert electrical energy into light energy in a larger proportion and thus have the advantage of saving energy, but it takes a long time to turn on the lamp, and its life is longer Short, the fact is that new media are needed because of the limitations.

LED (Light emitting diode, Light emitting diode) is developed for this purpose. Compared with tungsten filament bulbs, this kind of LED bulb has the advantages of high luminous efficiency, low power consumption, small size, light weight and long service life, which can reduce maintenance and management costs. , so the use of LED bulbs has increased rapidly. The following are prior art patent documents related to the LED lamps developed so far.
