For example, when the first lamp body 101 and the second lamp body 103 are movably connected, the position sensor 107 is used to detect a relative distance between the first lamp body 101 and the second lamp body 103 to allow the power supply unit of the circuit module 105 to control the brightness of the second lamp body 103 according to the distance between the first lamp body 101 and the second lamp body 103, e.g., the larger the distance, the smaller the power output by the power supply unit toward the second lamp body 103, the lower the brightness of the second lamp body 103; for another example, when the first lamp body 101 and the second lamp body 103 are rotatably connected, the position sensor 107 is used to detect a relative angle between the first lamp body 101 and the second lamp body 103, so as to allow the power supply unit of the circuit module 105 to control the brightness of the second lamp body 103 according to the angle between the first lamp body 101 and the second lamp body 103, for example, the larger the angle, the smaller the power output by the power supply unit toward the second lamp body 103, the lower the brightness of the second lamp body 103; for another example, the position sensor 107 may also serve as a trigger device of the circuit module 105, which can trigger the circuit module 105 to turn on or off according to data detected by itself to control the on/off of the first lamp body 101 and the second lamp body 103.

When the second lamp body 103 moves relative to the first lamp body 101, for example, the second lamp body 103 moves to a position relatively far away from the first lamp body 101, the lamp can control the brightness of the second lamp body 103 through the circuit module 105 according to the relative position information detected by the position sensor 107, so that the second lamp body 103 illuminates with lower brightness, and the low light illumination requirement of the user is met. Therefore, in the lamp 100, the first lamp body 101 and the second lamp body 103 are movably connected together, and the same circuit module 105 is used for controlling the first lamp body 101 and the second lamp body 103 to work, so that the lamp 100 can be combined with a structure with strong light illumination and weak light illumination, the structure is simple and compact, the number of the lighting lamps required by a user is effectively reduced on the basis of realizing multiple lighting functions, and convenience is provided for the user to use. Further, the lamp 100 can control the brightness of the second lamp body 103 via the circuit module 105 according to the relative position information of the first lamp body 101 and the second lamp body 103 detected by the position sensor 107, and the operation is simple and convenient in brightness control.

For example, when the first lamp body 50 and the second lamp body 70 are movably connected, the position sensor 34 is used to detect a relative distance between the first lamp body 50 and the second lamp body 70 to allow the power supply unit of the circuit module 32 to control the brightness of the second lamp body 70 according to the distance between the first lamp body 50 and the second lamp body 70, e.g., the larger the distance, the smaller the power output by the power supply unit toward the second lamp body 70, the lower the brightness of the second lamp body 70; for another example, when the first lamp body 50 and the second lamp body 70 are rotatably connected, the position sensor 34 is used for detecting a relative angle between the first lamp body 50 and the second lamp body 70 to allow the power supply unit of the circuit module 32 to control the brightness of the second lamp body 70 according to the angle between the first lamp body 50 and the second lamp body 70, for example, the larger the angle is, the lower the power output by the power supply unit towards the second lamp body 70 is, the lower the brightness of the second lamp body 70 is; for another example, the position sensor 34 may also serve as a trigger device of the circuit module 32, which can trigger the circuit module 32 to turn on or off according to data detected by itself to control on and off of the first lamp body 50 and the second lamp body 70. In some embodiments, the position sensors 34 include, but are not limited to including: at least one of a Hall sensor, an infrared sensor, an ultrasonic sensor and a laser sensor.

Further, in some embodiments, to protect the light emitter 54, the luminaire 200 may include a housing 54 connected to the support member 14, the light emitter 54 being disposed within the housing 52 and electrically connected to the circuit module 32. Of course, in other embodiments, the first lamp body 50 itself may also include a protective shell, and the light emitting element 54 may be disposed in the protective shell, which may be disposed in the housing 52, so that the first lamp body 50 itself forms a modular assembly, facilitating the installation of the lamp 200.

The housing 52 may be made of a material having a low light transmittance, such as colored plastic, acrylic, metal, etc., so that it can be used as a lamp cover. When the luminaire 200 is used as a table lamp, the housing 52 may block the light emitted by the light emitting member 54 in at least one direction to avoid the light directly irritating the eyes of the user. In the present embodiment, the housing 52 includes a top wall 521, a first side wall 523, and a second side wall 525. The top wall 521 is connected between the first side wall 523 and the second side wall 525, and the first side wall 521 and the second side wall 525 are oppositely arranged at intervals.

The first side wall 523 and the second side wall 52 are respectively disposed on two opposite sides of the top wall 521, so that the housing 52 can form a shading effect in three directions, which is beneficial for the light of the light emitting element 54 to be emitted in a concentrated manner in a specific direction, thereby improving the pertinence of the local illumination of the lamp 200 and avoiding dazzling of the light.

The light emitting component 54 may include a plurality of LED beads, and the LED beads can be lit when being powered on, and the amount of the lit LED beads is controlled, or/and the magnitude of the current input to the LED beads is controlled, so that the light emitting brightness of the first lamp body 50 and the light emitting brightness of the second lamp body 70 can be controlled, which is not limited in the embodiment of the present application. Further, the light emitting surface of the light emitting element 54 faces away from the top wall 521 of the housing 52. The inner surface of the housing 52 may be further coated with a reflective coating, so that the light of the light emitting element 54 is reflected and then emitted through the space between the first sidewall 523 and the second sidewall 525, which is beneficial to improving the utilization rate of the light.

In some embodiments, the first lamp body 50 may further include a light transmissive cover 56, and the light transmissive cover 56 is disposed between the first side wall 523 and the second side wall 525 and spaced opposite to the top wall 521. In this embodiment, the light-transmissive cover 56 may be connected between the first side wall 523 and the second side wall 525, and the light-transmissive cover 56 substantially covers the opening of the housing 52, so that the interior of the housing 52 substantially forms a relatively closed space, which is beneficial to prevent contaminants such as moisture, dust, liquid drops and the like from damaging the electronic devices in the housing 52. In the embodiment of the present application, the light transmittance of the light-transmitting cover 56 is greater than the light transmittance of the housing 52, and the light-emitting surface of the light-emitting body 54 faces the light-transmitting cover 56, so that the light rays 56 can be emitted through the light-transmitting cover 56. Further, the light-transmissive cover 56 may be doped with light-scattering particles, or its outer surface may be coated with light-scattering ink, so as to make the emitted light more uniform and soft. The material of the light-transmitting cover 56 is not limited, and it may be made of light-transmitting plastic, acryl, or the like.

The second lamp body 70 is movably connected to the first lamp body 50, for example, the second lamp body 70 may be connected to the housing 52 of the first lamp body 50. The movable connection structure between the first lamp body 70 and the second lamp body 50 is not limited, and the movable connection between the first lamp body 70 and the second lamp body 50 can be realized by a translational connection mechanism, or by a rotational or tilting mechanism.
