Description
本考案は、交流を定電流に変換するチップにより駆動させるＬＥＤに係り、特に、駆動回路により交流を定電流へ変換して電圧を出力し、発光モジュール上の発光素子を駆動させる技術に関する。 The present invention relates to an LED that is driven by a chip that converts alternating current into a constant current, and more particularly to a technique for driving a light emitting element on a light emitting module by converting the alternating current into a constant current by a drive circuit and outputting a voltage.
科学技術の発展に伴い、従来のランプはＬＥＤにより次第に代替されてきている。ＬＥＤは、低消費電力、長寿命（少なくとも５万時間の使用寿命があり、これは１日平均８時間使用した場合、約１７．５年間使用することができる）、小体積であるため、人々の生活において不可欠な照明源となっており、次世代の光源として期待されている。 With the development of science and technology, conventional lamps are gradually being replaced by LEDs. LEDs have low power consumption, long life (with a service life of at least 50,000 hours, which can be used for about 17.5 years when used for an average of 8 hours a day), and small volume, so people It is an indispensable illumination source in life and is expected as a next-generation light source.
例えば、特許文献１では、内部が中空を呈する透光管体と、透光管体内に置かれるＬＥＤ灯組と、それぞれ透光管体の両端口箇所に設けられた２つの導電端蓋と、回路制御ユニットと、を含む熱均等分布式ＬＥＤ灯管が開示されている。該回路制御ユニットは構造上、複数の部分に分離されて構成され、且つ該回路制御ユニットの各部分がＬＥＤ灯組の回路基板上に均等に分布してなる。これにより、回路制御ユニットの各部分が均等に分布され、ＬＥＤ灯管内部の熱量が均一となった。 For example, in Patent Document 1, a light-transmitting tube body having a hollow inside, an LED lamp set placed in the light-transmitting tube body, two conductive end caps respectively provided at both ends of the light-transmitting tube body, An evenly distributed LED lamp tube including a circuit control unit is disclosed. The circuit control unit is structurally divided into a plurality of parts, and each part of the circuit control unit is evenly distributed on the circuit board of the LED lamp set. Thereby, each part of the circuit control unit was evenly distributed, and the amount of heat inside the LED lamp tube became uniform.
しかし、従来のＬＥＤ灯組では、整流トランスにより家庭用交流電源１１０Ｖ〜２２０Ｖを直流に変換してから、直列に接続された電流制限抵抗により定電流を得ていた（一般にＬＥＤの定格電流は２０ｍＡである）。そのため、外部電圧の変動に伴い、電流制限抵抗を流れる電流が大幅に増減し、ＬＥＤの輝度および寿命に大きな影響を与えることがあった。さらに、電流制限抵抗の消費電力も多かったため、費用コストが高い上に二酸化炭素の排出量を抑えることが困難であった。 However, in a conventional LED lamp assembly, a home AC power supply 110V to 220V is converted into DC by a rectifier transformer, and then a constant current is obtained by a current limiting resistor connected in series (in general, the rated current of an LED is 20 mA). Is). For this reason, the current flowing through the current limiting resistor greatly increases and decreases with the fluctuation of the external voltage, which may greatly affect the brightness and life of the LED. In addition, since the power consumption of the current limiting resistor is large, the cost is high and it is difficult to suppress the discharge amount of carbon dioxide.
本考案の目的は、従来技術の問題点を解決することができる、交流を定電流に変換するチップにより駆動させるＬＥＤを提供することにある。 An object of the present invention is to provide an LED that can solve the problems of the prior art and is driven by a chip that converts alternating current into a constant current.

As shown in FIGS. 1, 4, 5, and 6, the light emitting module 1 is disposed in the waterproof housing 3, and the drive circuit 2 is disposed in the substrate housing 4. When the switch 42 is turned on after the plug 41 of the substrate housing 4 is connected to the external power source, an external AC voltage enters from the power input terminal 21 and passes through the fuse 28. If the AC voltage signal is overloaded, the fuse 28 The AC voltage signal of the fuse 28 is rectified by entering the bridge rectifier circuit 22 so that the current is automatically cut off and the heat generated by the overload does not damage the device, and a stable DC voltage signal is output and stabilized.
