BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a block diagram showing an embodiment of a table lamp device of the present invention. In one embodiment, the lamp unit 10 includes at least one light source 11 , at least one movable brightness sensing device 12 , and at least one controller 13 . The movable brightness sensing device 12 is configured to sense the brightness of the at least one light source 11. The movable brightness sensing device 12 includes at least one first wireless module 121 for transmitting a brightness signal of the light source. The controller 13 includes at least one second wireless module 131 for receiving a brightness signal of the light source. The controller 13 controls the brightness of the light source 11 according to the brightness signal of the light source.

In an embodiment, the lamp unit 10 can further include a lamp cover, a support frame and a base (the above components are not shown). The light source 11 is disposed in the lamp cover, and the support frame supports the lamp cover and connects the base and the lamp cover. The controller 13 can be disposed on the base. The at least one movable brightness sensing device 12 is not disposed in the lamp cover or the base, and is disposed separately from other components of the table lamp device 10. The at least one movable brightness sensing device 12 can be a brightness sensing device of a mobile phone or a professional portable brightness sensing device. Since the setting position of most of the lamp units is fixed and does not move frequently, the required brightness of the position should be fixed. Therefore, the above brightness sensing and control can be performed when the user uses the first time. Once, the controller 13 fixedly controls the brightness of the light source 11 to adjust the brightness for the first time, without having to make a brightness every time the lamp unit 10 is turned on. Sensing and control.

After the brightness of the light source 11 is sensed by the movable brightness sensing device 12, the brightness signal of the light source is transmitted to the controller 13 by using the first wireless module 121. After receiving the brightness signal of the light source, the controller 13 compares the brightness signal of the light source with a set brightness value, and the set brightness value can be elastically adjusted according to the set position of the lamp device 10. If the brightness signal of the sensed light source is greater than the set brightness value, it means that the brightness of the light source 11 needs to be lowered; if the brightness signal of the sensed light source is less than the set brightness value, it means that the brightness of the light source 11 needs to be increased. The controller 13 adjusts and controls the actual brightness of the light source 11 according to the brightness signal of the light source and the set brightness value to be close to the set brightness value or the same as the set brightness value.

Moreover, the bulb or the lamp tube has a light decay table at the factory, and the brightness of the light source can be periodically increased according to the light decay table and the accumulated operation time to compensate the light decay of the light source, so that the brightness of the light source can be kept fixed.

Since the brightness of the environment affects the total brightness of the position of the lamp unit 10, and when the ambient brightness is large (for example, when there is sunlight in the daytime), the light source 11 of the lamp unit 10 can output the brightness without having to output so much brightness. Need brightness. The lamp unit 10 further includes at least one fixed brightness sensing device 14 disposed on the at least one light source 11 for sensing the brightness of the environment. The at least one controller 13 includes at least one brightness calculation module 133, and calculates a control brightness according to the brightness signal of the light source and the brightness of the environment to control the brightness of the light source 11 to maintain a fixed brightness. In one embodiment, the control brightness is the difference between the brightness signal of the light source and the brightness of the environment. That is, the output brightness of the light source 11 is the control Brightness, reducing the output brightness of the light source 11 can save energy.

The controller 13 further includes a start control module 134 for controlling the operation of the light source 11 to perform a start control. In an embodiment, before starting the control, the startup control module 134 controls the light source 11 to perform a light-to-bright, light-to-dark start control operation to indicate that control will begin, and the confirmation is The light source 11 is controlled.
