[0047] See also Figure 1A and Figure 1B , which is a configuration diagram of a desk lamp according to an embodiment of the present application and a configuration diagram of a light sensor switch according to an embodiment of the present application. Figure 1A and Figure 1B As shown, the table lamp includes a base 10, a fixing base 20, a cantilever 30, a lamp holder 40, a light sensor switch 50 and a microcontroller 60. The fixing base 20 is arranged on the base 10. One end of the cantilever 30 is pivotally connected to the fixing base 20. The lamp holder 40 is pivotally connected to the other end of the cantilever 30 and has a light-emitting element 41. The light sensor switch 50 is arranged on the base 10 and includes a light source 51 and a light sensor 52. The light source 51 emits incident light. When approaching the light sensor switch 50, the incident light is reflected from the skin to the light sensor 52, and the light sensor 52 generates a sensing signal. The microcontroller 60 is arranged in the base 10 and is electrically connected to the light source 51, the light sensor 52 and the light-emitting element 41. The microcontroller 60 controls the light emission of the light-emitting element 41 according to the sensing signal.

[0048] In this embodiment, the base 10 is a rectangular plate, and the fixing base 20 is disposed on the short side of the rectangular plate; specifically, the fixing base 20 can be fixed to the base 10 by screwing or clamping. First pivot holes are respectively disposed on both sides of the fixing base 20, and one end of the cantilever 30 is pivotally connected to the first pivot hole by passing through a first pivot axis PA1. The lamp holder 40 has a connecting member 42, and second pivot holes are disposed on both sides of the connecting member 42, and the other end of the cantilever 30 is pivotally connected to the second pivot hole by passing through a second pivot axis PA2. In other words, the two ends of the cantilever 30 are pivotally connected to the fixing base 20 and the lamp holder 40 respectively.

[0049] The light-emitting element 41 includes a mounting base, an acrylic plate, and a plurality of light-emitting diodes (LEDs). The mounting base accommodates the plurality of LEDs, which are arranged in a rectangular array. The acrylic plate and the peripheral side of the mounting base are bonded to each other so that the plurality of LEDs are adjacent to the acrylic plate. The plurality of LEDs emit self-luminous light or yellow light.

[0050] In this embodiment, the light sensor switch 50 further includes a substrate SUB1 and a resin layer 53. The light source 51 and the light sensor 52 are disposed on the substrate SUB1 and are spaced apart from each other; in other words, the light source 51 and the light sensor 52 are located on the same plane and are independently disposed. The resin layer 53 is disposed on the light source 51 and the light sensor 52 to cover the light source 51 and the light sensor 52, thereby protecting the light source 51 and the light sensor 51 from damage. The light source 51 can be an LED and the light emission band of the light source 51 is a visible light band. The light sensor 52 can be a silicon sensor.

[0051] The substrate SUB1 may be a glass substrate, a quartz substrate or a sapphire substrate. The types of the substrate SUB1 are only examples and are not intended to limit the present application. The material of the resin layer 53 may include epoxy resin, acrylic resin, silicone resin, phenolic resin, polyimide resin or imide resin. The materials of the resin layer 53 are only examples and are not intended to limit the present application.

[0052] When the user's finger approaches the optical sensor switch 50, the light source 51 emits incident light, which passes through the resin layer 53 and is blocked at the contact surface between the resin layer 53 and the user's finger. The incident light is reflected from the skin of the user's finger to produce reflected light, which passes through the resin layer 53 and enters the optical sensor 52. The optical sensor 52 generates a sensing signal according to the reflected light. Then, the optical sensor 52 transmits the sensing signal to the microcontroller 60, which generates and transmits a control signal to the multiple light-emitting diodes of the light-emitting element 41 according to the sensing signal, and the multiple light-emitting diodes emit light accordingly.

[0053] At the same time, the microcontroller 60 generates and transmits a feedback signal to the light source 51 according to the sensing signal, and the light source 51 adjusts the luminous intensity of the incident light according to the feedback signal. In addition, the microcontroller 60 controls the light source 51 to periodically emit incident light, for example, the microcontroller 60 controls the light source 51 to emit incident light every 3 seconds.

[0054] When the user's finger touches the light sensor switch 50 twice, two incident lights pass through the resin layer 53 and enter the skin of the user's finger respectively. The two incident lights are reflected from the skin of the user's finger as two reflected lights. The light sensor 52 generates two sensing signals according to the two reflected lights. Then, the light sensor 52 transmits the two sensing signals to the microcontroller 60. The microcontroller 60 generates and amplifies the control signal according to the two sensing signals, and transmits the amplified control signal to multiple light-emitting diodes. The multiple light-emitting diodes emit light accordingly, and the light intensity of the multiple light-emitting diodes is enhanced. In other words, the microcontroller 60 adjusts the light intensity of the light-emitting element 41 according to the number of sensing signals. Furthermore, the desk lamp can adjust the light intensity of the light-emitting element 41 according to the brightness requirements of the user.

[0055] See also Figure 2 , which is a configuration diagram of a light sensing switch according to another embodiment of the present application. Figure 2 As shown, the optical switch 50 includes a substrate SUB1, a light source 51, a light sensor 52, a first resin layer 53A and a second resin layer 53B, wherein the configuration and operation of the light source 51 and the light sensor 52 have been described in detail. Figure 1A and Figure 1B The above is described in the embodiment shown in the figure and will not be repeated here.

[0056] The photo sensor 52 is disposed on the substrate SUB1, the first resin layer 53A is disposed on the photo sensor 52, the light source 51 is disposed on the first resin layer 53A, and the second resin layer 53B is disposed on the light source 51. Specifically, the first resin layer 53A covers the photo sensor 52 to protect the photo sensor 52 from damage, the second resin layer 53B covers the light source 51 to protect the light source 51 from damage, the photo sensor 52 is located between the first resin layer 53A and the substrate SUB1, and the light source 51 is located between the first resin layer 53A and the second resin layer 53B. The materials of the first resin layer 53A and the second resin layer 53B and the material of the resin layer 53 are not repeated here.

[0057] In other words, the light sensor 52 and the light source 51 are located on different planes, the projection of the light sensor 52 on the substrate SUB1 does not overlap with the projection of the light source 51 on the substrate SUB1, and the distance between the light source 51 and the surface of the second resin layer 53B is smaller than the distance between the light sensor 52 and the surface of the second resin layer 53B.

[0058] See also Figure 3 , which is a configuration diagram of a desk lamp according to another embodiment of the present application. Figure 3 As shown, the desk lamp includes a base 10, a lamp body 70, a light sensor switch 50 and a microcontroller 60, wherein the configuration and operation of the light sensor switch 50 and the microcontroller 60 have been described in detail. Figure 1A and Figure 1B The above is described in the embodiment shown in the figure and will not be repeated here.

[0059] like Figure 3 As shown, the base 10 is a circular plate, and the lamp body 70 includes a support arm 71 and a light-emitting element 72. One end of the support arm 71 is disposed on the base 10, and the light-emitting element 72 is disposed at the other end of the support arm 71. Specifically, the base 10 has a circular groove, one end of the support arm 71 is engaged with the circular groove, and the other end of the support arm 71 is connected to the light-emitting element 72.

[0060] The light emitting element 72 is annular and includes an annular mounting seat, a light guide plate, a diffusion plate, a plurality of light emitting diodes and an acrylic plate. The annular mounting seat accommodates the light guide plate, the diffusion plate and the plurality of light emitting diodes. The plurality of light emitting diodes are arranged in an annular shape around the periphery of the light guide plate, the light guide plate is disposed on the diffusion plate, the diffusion plate is adjacent to the acrylic plate, and the acrylic plate and the peripheral side of the annular mounting seat are connected to each other. The plurality of light emitting diodes emit white light or yellow light, the light guide plate guides the white light or yellow light to the diffusion plate, and the diffusion plate makes the brightness of the light or yellow light uniform.

[0061] In summary, the desk lamp of the present application generates a sensing signal by sensing the approach of a finger through a light-sensing switch, and the microcontroller controls the light-emitting element to emit light according to the sensing signal, thereby bringing convenience to people in using the desk lamp. In addition, the microcontroller adjusts the light intensity of the desk lamp according to the number of sensing signals generated by the approach of a finger, so as to meet the light intensity requirements of each user for the desk lamp.
