Description

Technical Field

[0001] This utility model relates to the field of optoelectronic manufacturing technology, specifically to a light-emitting diode with built-in driver. Background Technology

[0002] Light-emitting diodes, or LEDs for short, are a common type of light-emitting device that can directly convert electrical energy into light energy. They are made of semiconductor materials such as gallium phosphide and emit light when a certain current passes through them. LEDs are widely used in various electronic circuits, home appliances, instruments and other equipment as power indicators or level indicators.

[0003] The color of light emitted by an LED depends on its manufacturing materials. It can emit monochromatic light such as red, yellow, and green. In addition, early LEDs could only emit low-intensity red light. Later, versions with other monochromatic light were developed, and the intensity of light gradually increased. Now, LEDs are widely used in lighting, flat panel displays, medical devices and other fields.

[0004] Existing LEDs have strong light directionality and a small illumination angle, which limits their application in some situations where a larger illumination angle is required. Therefore, a light-emitting diode with built-in driver is proposed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention provides a light-emitting diode with built-in driver, which overcomes the shortcomings of the prior art and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a light-emitting diode with built-in driver, including an encapsulation lens, a base plate formed at the bottom end of the encapsulation lens, an alignment card interface extending through the bottom end of the base plate, a cathode pin and an anode pin being fixedly installed sequentially at the bottom end of the encapsulation lens, a cathode assembly being fixedly connected to the top end of the cathode pin through the base plate, and a wire being fixedly connected to the top end of the anode pin through the base plate, a base shell being installed below the encapsulation lens, and a driver being installed inside the base shell.

[0007] The driver can provide appropriate current and voltage to chip one and chip two, enabling them to emit light normally. Chip two can emit side lighting, improving the lighting effect, increasing the light illumination angle, and meeting the needs of applications requiring a larger illumination angle.

The current connected through the power pin can be processed by the driver to provide appropriate current and voltage for the illumination of chip one and chip two. The alignment card connector can be used to connect with the alignment card interface.

The top end of the power-connecting pin extends through the bottom cover into the interior of the base shell, and the top end of the power-connecting pin is electrically connected to the driver.

[0015] The adapter pins can be connected to the cathode and anode pins respectively via the mounting slots at the top. The spacing between the adapter pins can also be adjusted according to the different positions of the cathode and anode pins. The bottom of the adapter pins can be inserted into a sliding platform, which can slide freely along the adjustment groove to adapt to the position of the adapter pins, thus accommodating the connection of the cathode and anode pins at different positions. The sliding platform is electrically connected to the driver, and the appropriate current and voltage provided by the driver can be conducted through the sliding platform for power supply.
