Description

Light-emitting diode bulb structure

This creation is about the structure of the bulb, especially a light-emitting diode bulb structure in which the electrodes can be inserted and mounted.

Due to the advantages of easy installation of the bulb, incandescent bulbs are often used for night or indoor lighting, but incandescent bulbs have the disadvantages of high power consumption and short service life. In addition, the LED has a fast response and small volume. It has the advantages of electricity saving, low pollution, high reliability, and suitable mass production. Therefore, under the premise of pursuing energy conservation and environmental protection, the LED bulb gradually replaces the incandescent bulb.

Since the structure of the light-emitting diode bulb contains more electronic components than the conventional incandescent light bulb, the assembly procedure of the light-emitting diode bulb is more complicated than the conventional incandescent light bulb. Therefore, the structural design of the current light-emitting diode bulb needs to consider the convenience of assembly. For example, the TW M409543 patent discloses a light-emitting diode bulb comprising a frame and a plurality of terminals disposed on the frame, the terminals being soldered to a conversion circuit, and the conversion circuit converting the AC input into a DC output to each terminal . The frame is used to set the LED array, so as long as the frame and the LED array are combined, the terminals will contact and electrically connect the LED array to supply DC power to the LED array. However, the prior art has a disadvantage in that a solder joint is still required between the terminal and the conversion circuit, so that the structure cannot be assembled quickly.
