Abstract
A current-limiting LED indication bulb with current being less than 50mA comprises an LED with current being less than 50mA, a bulb cap and a bulb holder. An opening end of the bulb cap sleeves and is fixed inside the bulb holder. The LED is arranged in a space formed by the bulb cap and the bulb holder through packaging. The bulb holder includes a metal joint sleeve and an insulation cap which is disposed at the bottom end of the metal joint sleeve. A conductive head passes through the insulation cap. The LED indication bulb also comprises a printed circuit board. Two pins of the LED are welded to one end of one conductive film and one end of the other conductive film of the printed circuit board respectively. The other end of one of the conductive films is connected with the conductive head on the insulation cap via a first conductive wire, and the other end of the other conductive film is connected with the sidewall of the metal joint sleeve via a conductor. Through the above technical scheme, the LED indication bulb is convenient to replace, low in power and energy-saving. The enclosed pins are not liable to oxidize so as to be durable. In a word, the LED indication bulb is convenient to replace, has a nice appearance, is low in cost, and is suitable for being applied to handicrafts such as antique decorative handicrafts.
