Encoder with three-color LED's

Encoder with three-color light-emitting diode

This creation is about an encoder, especially an encoder that has both a three-color LED and a key switch, and is suitable for electronic products, such as encoders for audio, mixing engineering equipment, audio-visual equipment, etc.

For general electronic products, such as audio, mixing engineering equipment, audio-visual equipment, etc., an insulated shaft is assembled, and the insulation shaft is pressed to achieve the switching function of the so-called switch device.

Furthermore, in order to further strengthen the function of the switchgear, an encoder will be installed on the switchgear mentioned above, so the switchgear mentioned above can have both the functions of switch and code at the same time.

However, in places where the light is darker, such as movie theaters and homes when the audio and video equipment is used and the lights are turned off, when you want to use the above switch and encoder equipment, you must have a light as a guide.

Traditionally, a light-emitting diode (LED: Light Emitting Diode) is assembled on the substrate of the above electronic product to generate light. However, when the aforementioned light-emitting diode is assembled on the substrate, the above-mentioned code is required. It is difficult to integrate the height and brightness of the light-emitting diode due to the location of the device.

Moreover, when assembling the above-mentioned light-emitting diodes, one additional procedure is required in the manufacturing process. For example, an additional soldering process is required to assemble the light-emitting diodes. Therefore, the manufacturing time will increase and the cost will also increase. , And the high temperature of the soldering process can easily affect the function of the light-emitting diode chip. In addition, the traditionally assembled light-emitting diode has only a single color, and the color cannot be changed according to usage requirements, which is not very ideal.

This is the reason for the creator. Based on the spirit of active invention and creation, he was eager to think of a "encoder with three-color light-emitting diode" that could solve the above problems. After several research experiments, he finally completed the creation.

The main purpose of this creation is to provide an encoder with three-color light-emitting diodes that can control the mixed colors through the voltage changes of independent circuits of red, green, and blue light-emitting diodes, which are combined with key switches and In the encoder, it is used as a lighting indicator.

Another purpose of this creation is to provide an encoder with three-color light-emitting diodes, so that the three-color light-emitting diode assembly, encoder, and key switch can be integrated into one body, and each is operated independently, and the terminal is stamped. The technology of plastic injection molding together with the insulating base does not need to be installed by welding, which can avoid the traditional surface adhesion process that is susceptible to high-temperature processes, and there will be no problems with height and brightness integration. At the same time, it can be controlled differently. The functions of mixed color light, key switch and encoder can simplify the structure design and manufacturing process, achieve the purpose of lightness, thinness and shortness, and reduce the cost.
