- LED components usually refer to LED beads or LED light sources.
- An LED component normally includes a frame and an LED chip sealed in the frame.
- the frame of such LED components usually includes an insulated main body, such as a plastic base or a ceramic base.

Description
- The following substitute specification contains no new matter.
- The present invention relates generally to the technical field of LED lights, and more particularly to an LED strip, manufacturing method thereof, and LED components used therein.
- LED components usually refer to LED beads or LED light sources. An LED component normally includes a frame and an LED chip sealed in the frame. At present, as LED components adopting RGB light source requires a built-in control chip unit, they usually have more than two leads. The frame of such LED components usually includes an insulated main body, such as a plastic base or a ceramic base. The insulated main body is provided with a holding chamber. The insulated main body is integrally fixed with a plurality of conductive leads. One end of the lead is extended into the holding chamber, to form a contact terminal, the other end of the lead is extended to the outer surface of the insulated main body (normally the bottom surface) to form a soldering portion (also called soldering disc). During manufacturing, the LED chip and the control chip units are fixed inside the holding chamber, and are connected to each lead terminal through wires. Finally, transparent plastic material is filled into the holding chamber to complete the packaging operation and form the LED component.
- When using the LED component product to produce an LED strip, a plurality of LED components is directly soldered on the wire set to form an LED strip. The wire set at least includes power wires and signal wires. Due to the special manufacturing technique of this kind of products, to facilitate manufacturing, the wires must be fully continuous from the starting point to the ending point, so as to connect a plurality of LED components. All the LED components are connected in parallel. However, to make color-changing LED strip lights, in order to change the light source colors of each LED component, they must be input with corresponding control signals. The control signals are transmitted in series. The control signals are transmitted through the signal wire from the first LED component to the second LED component, and after outputting from the second LED component, they are further transmitted to the third LED component. As mentioned above, during manufacturing, to facilitate production, the frames of all LED components are directly connected to the signal wire. Thus, all LED components are connected in parallel. Therefore, in order to realize signal transmission in series and to change the above-the parallel connection to series connection, the signal wire must be cut between the input end and output end of the LED component. If the cutting operation for the signal wires is carried out after production, it will be very difficult because the LED frame normally has a square or round design and its soldering portion is basically a plane surface. If the cutting operation for the signal wires is carried out before production to form signal wire segments, and the signal wire segments are soldered between the signal transmission conductive terminals of the LED components, the operations will be far more difficult. Also, due to the tension of the wire material itself, the end portion of the cut signal wire segments will not be maintain on a relatively even surface. As a result, during SMT soldering, solder skips or solder joint failure will easily happen, causing bad quality of the LED component products and high cost of production.
