Problems solved by technology

[0005] Traditional desk lamps generally use incandescent bulbs or compact fluorescent tubes as light sources, and their functions are relatively single, with only switch functions, and individual configurations have 1-2 dimming functions.
Because the LED light source has many advantages such as full curing, high reliability, and good energy-saving effect, there have been many desk lamps using LED as the light source. Or fluorescent lamps, some ...

Example Embodiment

[0055] Such as figure 1 with figure 2 As shown, an intelligently controlled LED desk lamp includes a switch, a lamp body, and a light source assembly. The lamp body is provided with a first sensing device 41 and a second sensing device 42; the light source assembly includes a first color temperature light source 21 and a second color temperature light source 22 ; Also includes a first controller 31 and a second controller 32, the first controller 31 and the second controller 32 include:
[0056] -Timing module, used to time the user triggering the sensing device;
[0057] -Storage module, used to store the current intensity passing through the light source when the user stops triggering the sensing device;
[0058] -Adjustment module, used to adjust the current intensity through the light source;
[0059] -Central control module, respectively connected with timing module, storage module and control module;
[0060] The first sensing device 41 and the second sensing device 42 are respectively connected to the central control modules of the first controller 31 and the second controller 32; the first color temperature light source 21 and the second color temperature light source 22 are respectively connected to the first A controller 31 is connected to the control module of the second controller 32; the first sensing device 41 and the second sensing device 42 are used to sense the trigger behavior of the user.
[0061] In this embodiment, the first and second sensing devices 41, 42 use touch capacitive sensors, and the areas on the sensing devices for receiving touches are called the first and second sensing regions 11, 12.
[0062] The color temperature of the first color temperature light source 21 can be selected in the range of 2000-3500K, and the color temperature of the second color temperature 22 light source can be selected in the range of 5000-10000K, which can be specifically determined according to actual requirements.
[0063] The control module is used to "increase-decrease" the intensity of the current passing through the light source, and can turn on or off the current passing through the light source. In this embodiment, the current changes linearly with the touch time.
[0064] In this embodiment, the first set time is 1 s, and the second set time is 2 s.
[0065] When the lamp leaves the factory, the maximum standard output current and the minimum standard output current are preset in the central control module.
[0066] Such as image 3 As shown, the intelligent control LED desk lamp can be used in the following ways:
[0067] First, turn on the power switch;
[0068] Next, touch the first sensing device 41. The part for sensing the touch is the first sensing area 11 located on the upper side of the lamp body. The first sensing device 41 transmits the response signal to the central control module of the first controller 31 , The central control module determines whether the current first color temperature light source 21 is working,
[0069] (1) If not in operation, the timing module starts timing; when the user stops triggering the first sensing device 41, the timing module stops timing and obtains the trigger time; if the trigger time is less than 1 second, the central control module will check the storage module Whether the value of the last working current is stored, if so, the central control module of the first controller 31 issues an instruction, the control module makes the first color temperature light source 21 start working, and sets the current working current through the light source to The stored value; if the storage module does not store the last working current, the central control module uses the maximum standard output current preset at the factory to let the control module make the first color temperature light source 21 work; if the user touches the first sensing device 41 Touch for more than 1 second, the central control module does not make any response action, and the first color temperature light source 21 does not work.
[0070] (2) If it is working, the timing module starts timing; in this process, if the user stops touching within 2 seconds, the central control module of the first controller 31 will issue an instruction, and the control module will lead to the first The output current of the color temperature light source 21 is set to zero, and the first color temperature light source 21 stops working. If the user keeps touching the first sensing device 41 for more than 2 seconds, then starting from 2 seconds, the central control module of the first controller 31 issues an instruction to make the control module start from the preset minimum standard output current and follow The user’s touch time gradually increases the current passing through the first color temperature light source 21. During this process, if the user stops touching, the central control module stores the current value of the current passing through the first color temperature light source 21 into the storage module, and then The timing module stops timing, and the first color temperature light source 21 maintains its current working state; if the user does not stop touching, the control module will increase the current until the preset maximum standard output current is reached. When this value is reached, the central control The module issues instructions to change the control direction of the control module, so that the current gradually decreases with time. In this process, if the user stops touching, the central control module will also pass the current light source 21 of the first color temperature. The current value is stored in the storage module, and then the timing module is stopped, and the first color temperature light source 21 maintains the current working state; if the user does not stop touching, the control module will continuously reduce the current until the minimum standard output current is reached. When the value is set, the central control module again causes the control module to change the control direction, so that the current increases with the touch time, that is, a new cycle process is started. In this process, when the user thinks that the light intensity is more appropriate, they can stop touching at any time. The central control module stores the current working status in the storage module, and the central control module issues an instruction to stop the timing module. The first color temperature light source 21 Maintain the current working state. If the user does not need to use the first color temperature light source 21, he can touch the first sensing device for a short time (less than 2 seconds), and the central control module of the first controller issues an instruction, and the control module stops outputting current to the first color temperature light source 21 , The first color temperature light source 21 stops working.
[0071] Next, the user can touch the second sensing device 41 by the same method, so as to achieve the effect of using the second controller 32 to adjust the brightness of the second color temperature light source 22. When the user adjusts the intensity of the second color temperature light source 22, the light generated by the second color temperature light source 22 will be matched with the light of the first color temperature light source 21. When the user thinks that the lighting effect of the light is suitable, the second sensing device is stopped. The touch of 42 makes the luminous effect of the entire table lamp reach the user's needs. The next time the desk lamp is turned on, the first and second sensing devices 41, 42 can be touched for a short time, and the light-emitting effect can be maintained at the size of the previous time, thereby simplifying the operation.
[0072] After use, turn off the power of the lamp.
