Abstract
A light-emitting diode (LED) light source includes a plurality of electricity-conducting holding elements, and each electricity-conducting holding element is made of a thin metal sheet. The bendable LED light source increases installation of sufficient number of LED dies by lengthening the length of the LED light source. The LED light source is bent to form a spring-like helical structure and then is placed inside a lamp cover. The helical LED light source is fastened on a T-shaped element by a plurality of fastening elements and the T-shaped element is fixed on an insulated holder. Accordingly, a bulb-type LED lamp is implemented.
Claims20
A light-emitting diode (LED) light source comprising:
- a plurality of LED dies;
- and
- a plurality of electricity-conducting holding elements being metal sheets respectively;
- wherein adjacent two of the electricity-conducting holding elements are configured to jointly hold and electrically connect to one of the LED dies to form a flexible LED light bar.
