Description

Lighting device and its driving structure

The present invention relates to a lighting device, in particular to a lighting device with high assembly efficiency.

Please refer to FIG. 1 , which is a structural diagram of a conventional incandescent bulb or a tungsten filament bulb, which is also a structural diagram of a bulb disclosed in US Pat. No. 3,784,867. The light bulb structure 1 includes a light-emitting element 11, a contact pin 12, a sleeve 13 and a conductive compression spring 14, and one end of the light-emitting element 11 is fixed in the sleeve 13 and has a first electrical pin 111 and a second electrical pin. The sleeve 13 is configured to receive the conductive compression spring 21114 and at least a portion of the contact pin 12, and the contact pin 12 is movable in the sleeve 13, and one end of the sleeve 13 further has a hole 131 for at least Part of the contact nail 12 is extended.

Moreover, both ends of the conductive compression spring 14 are respectively connected to the first electrical pin 111 and the contact pin 12, and one end of the second electrical pin 112 of the light-emitting element 11 is exposed outside the sleeve 13 and electrically connected. An electrical flange 132 on the side of the sleeve 13. Wherein, when the bulb structure 1 is assembled in an electrical socket (not shown) that is connected to an external power source, the contact pins 12 and the electrical flanges 132 of the bulb structure 1 are respectively in contact with the electrical property. The two electrode portions of the lamp holder are electrically connected, so that the electric energy of the external power source can be transmitted to the light-emitting element 11 via the first electrical pin 111 and the second electrical pin 112, thereby driving the light-emitting element 11 to provide illumination light.

In particular, since the conductive compression spring 14 can provide an elastic force to the contact pin 12 to push the contact pin 12 to move outside the hole 131 of the sleeve 13, when the bulb structure 1 is assembled to the electric lamp holder, the contact pin 12 is It can be kept in contact with the electrode portion of the electric lamp holder. It can be seen that the conventional bulb structure 1 overcomes the past poor contact due to assembly by connecting the compression spring 211 between the light-emitting element 11 and the contact pin 12. This causes the bulb structure 1 to fail to emit light.

However, with the rapid development of science and technology, Light Emitting Diode (LED) has replaced traditional incandescent bulbs or tungsten bulbs in recent years. The main reason is that it has energy saving and advantages, so the display, home appliances, Automotive electronic components, lighting fixtures, etc. are all applications of light-emitting diodes. For example, when a lighting diode is used as a light source by using a lighting fixture, it can bring a warm lighting time, a fast response speed, a small volume, a long life, a power saving, a shockproof, a low degree of pollution, and a high reliability. Suitable for mass production and many other advantages.

Please refer to FIG. 2 , which is a structural diagram of a conventional LED lamp, which is also a structural diagram of an LED lamp disclosed in Chinese Patent No. 201628118. The LED lamp 2 includes an electric lamp cap 21, a bulb shell 22, a plurality of LEDs 23, a T-shaped fixing plate 24, and a wire 25, and the electric lamp cap 21 includes a compression spring 211 and a contact pin 212. The pole body 23 is disposed on the T-shaped fixing plate 24, generally The T-type fixing plate 24 is a circuit board for transmitting power to the light-emitting diodes 23 when being powered. Further, the T-shaped fixing plate 24 is electrically connected to the contact pins 212 through the wires 25 . Therefore, when the electric lamp cap 21 is assembled in an electric lamp holder (not shown) connected to the external power source, the T-type fixing plate 24 can obtain electric energy from the external power source, thereby driving the light-emitting diode 23 to provide Lighting light. It is to be noted that the LED lamp 2 also pushes the contact pin 212 outward by the elastic force of the contact pin 212 by the compression spring 211, so that the contact pin 212 is kept in contact with the electrode portion of the electric lamp holder.

However, the assembly process of the LED lamp 2 on the production line is quite cumbersome, because it is necessary to specifically solder the two ends of the wire 25 to the T-shaped fixing plate 24 (circuit board) and the contact nail 212, so that the T-shaped fixing plate can be made. 24 (circuit board) is electrically connected to the contact pin 212, but such a method not only consumes production man-hours, but also consumes production line manpower, which does not meet economic and efficiency considerations.
