By controlling the on-off and brightness of different lamp beads, the applicator can provide multiple phototherapy modes to meet the individual needs of different users.

[0076] Specifically, the LED lamp beads can be red light LED lamp beads, because red light LED lamp beads have good penetration and treatment effect in phototherapy, and can effectively promote the repair and regeneration of skin cells. In addition, the use of red light LED lamp beads can also reduce the thermal damage to the skin, making the phototherapy process safer and more comfortable.

[0077] In this embodiment, please refer to Figure 2 and Figure 3 The skin detection element 2 includes two detection probes 201, and the liquid outlet 133 is located between the two detection probes 201.

One end of the spring needle 202 is electrically connected to the lamp panel, and the other end of the spring needle 202 penetrates through the end cover 130 and abuts against the detection probe 201.

[0078] In this embodiment, by providing the detection probe 201 and the spring needle 202, the applicator can monitor the skin condition in real time and automatically adjust the brightness and mode of the phototherapy lamp according to the detection result. This intelligent skin detection and feedback mechanism ensures that the applicator can provide more personalized and accurate skin care during use. Due to the existence of assembly error and machining error, the distance between the detection probe 201 and the lamp panel may become larger or smaller. The spring needle 202 is a conductor and has elasticity, which can adapt to the change of the distance, thereby ensuring the electrical connection between the detection probe 201 and the lamp panel.

The liquid outlet 133 is arranged on the liquid outlet light guide 132, and the light emitted by the phototherapy element 10 can pass through the liquid outlet light guide 132 and be emitted.

[0080] In this embodiment, the material of the liquid outlet light guide 132 has good light transmission, ensuring effective transmission of light. In addition, the shape design of the liquid outlet light guide 132 helps to evenly distribute the light, thereby providing uniform phototherapy effect for the skin during application. The connection between the end cap body 131 and the liquid outlet light guide 132 can be through adhesion, heat pressing or other mechanical fixing methods to ensure the firmness and sealing of the connection.

[0081] In this embodiment, as shown in Figure 2 , one end of the liquid outlet light guide 132 has a protruding part 1323, the protruding part 1323 forms a liquid outlet 133 penetrating through the liquid outlet light guide 132, and the protruding part 1323 is inserted on the pipeline 3; as shown in Figure 6 , the bracket 6 is also provided with a relief hole 605 for the pipeline 3 to pass through.
