Description
本实用新型涉及一种灯具，尤其是一种具有警示功能的节能灯具，属于发光器具技术领域。The utility model relates to a lamp, in particular to an energy-saving lamp with a warning function, which belongs to the technical field of light-emitting devices.
目前，公知的警示灯通常采用功率在25W以上的白炽灯泡。其缺点是耗电，并且在频闪示警的工作条件下容易损坏灯丝，寿命很短。At present, known warning lights usually adopt incandescent bulbs with a power above 25W. Its disadvantage is that it consumes power, and it is easy to damage the filament under the working condition of strobe warning, and its life is very short.
本实用新型的目的在于：针对上述现有警示灯存在的问题，提出一种使用寿命长、并且节能的专用警示灯。The purpose of the utility model is to propose a special warning light with long service life and energy saving in view of the problems existing in the above-mentioned existing warning lights.
为了达到上述目的，本实用新型长效节能警示灯包括发光二极管，整流电路以及频闪控制电路，所述频闪控制电路由可控硅、二极管、电容、电阻组成，发光二极管与可控硅串联，可控硅的正极经串联的反向二极管、放电电阻，并经充电电阻接电容的正极，可控硅的控制极经分压电阻接电源负极，并经旁路电阻接电容正极，可控硅和电容的负极均接电源负极。In order to achieve the above object, the long-acting energy-saving warning lamp of the utility model includes a light-emitting diode, a rectifier circuit and a stroboscopic control circuit. The stroboscopic control circuit is composed of a thyristor, a diode, a capacitor, and a resistor. , the positive electrode of the silicon controlled rectifier is connected to the positive electrode of the capacitor through the reverse diode and the discharge resistor connected in series, and the positive electrode of the capacitor is connected through the charging resistor; Both silicon and the negative poles of the capacitor are connected to the negative pole of the power supply.
本实用新型的长效节能警示灯通电后，电流通过限流电阻、整流电路、发光二级管、R3给电容充电，这时候发光二极管微亮。一旦电容上的充电电压使致R5、R4的分压达到可控硅导通电压时，ST导通，发光二极管全亮。这时电容立即通过R2、D5、ST放电，ST关断后，电容又开始充电，从而完成循环，产生闪烁。由于发光元件采用发光二极管全串连接，并有与之合理匹配的频闪控制电路，因此本实用新型的警示灯节省电能，使用寿命长。推广之后，将受到用户的欢迎，取代现警示用的白炽灯。After the long-acting energy-saving warning lamp of the utility model is energized, the electric current passes through the current limiting resistor, the rectifier circuit, the light-emitting diode and R3 to charge the capacitor, and at this time the light-emitting diode is slightly bright. Once the charging voltage on the capacitor causes the divided voltage of R5 and R4 to reach the conduction voltage of the thyristor, the ST is turned on and the LEDs are all bright. At this time, the capacitor is immediately discharged through R2, D5, and ST. After the ST is turned off, the capacitor starts to charge again, thus completing the cycle and generating flicker. Since the light-emitting elements are connected in series with light-emitting diodes and have a reasonably matched strobe control circuit, the warning light of the utility model saves electric energy and has a long service life. After the promotion, it will be welcomed by users and replace the incandescent lamps used for warning.
