[0030] Reference Figures 1 to 8 As shown, an intelligent dimmer of the present invention includes a housing, in which an on-off component for a lamp source circuit and a dimming component for dimming the lamp source are installed, the on-off component includes a first button device arranged on the housing, and the dimming component includes a second button device 9 arranged on the housing, and the brightness of the lamp source is adjusted by pressing the second button device. In this embodiment, the structure of the intelligent dimmer also includes a PCB board 2, on which a chip, a capacitor, an inductor and a light guide are arranged, the on-off component also includes a static contact and a moving contact component 704, the first button device controls the on-off of the moving contact component 704 and the static contact, and the second button device 9 also includes a column and a contact under the button, and the contact is connected to the PCB board 2. In this embodiment, the dimming component adopts a push-type dimming, and is provided with an up-adjustment button and a down-adjustment button. Its working modes include point pressing and continuous pressing. The intelligent dimmer is preset with multiple light intensity levels. When point pressing (i.e., pressing and lifting the button once), the light intensity is adjusted step by step. When pressing continuously (pressing the button and holding it), the level is adjusted continuously. The up-adjustment button and the down-adjustment button have similar functions, the difference being that the up-adjustment button increases the light intensity, while the down-adjustment button decreases the light intensity. A number of LED indicator lights 201 are provided on both sides of the PCB board 2. The indicator lights 201 indicate whether the light intensity is adjusted downward or upward or indicate the adjusted level through light changes. The PCB board 2 and its circuit structure refer to Fig. 9 and Fig.10 The intelligent dimmer of this embodiment is not only applicable to LED lamps, but also to other lamps, such as Wusi lamps, energy-saving lamps, etc.

[0031] In the above embodiment, referring to Figure 2 As shown, the pressing pieces of the upward adjustment button and the downward adjustment button are in an inverted concave shape, and a limit block cooperating with the second button mounting groove 602 is provided on the outer plate of the pressing piece. The second button mounting groove 602 includes a fixing plate at the bottom, and holes are provided on both sides of the fixing plate. A stop block is provided on the groove wall of the second button mounting groove 602 to cooperate with the limit block. A button spring 901 is connected to the column. The limit block prevents the upward adjustment button or the downward adjustment button from popping out. The holes on both sides of the fixing plate are for the outer plate of the pressing piece to pass through, so that the pressing piece has sufficient travel, and the button spring is used to reset the upward adjustment button or the downward adjustment button.

[0032] In the above embodiment, referring to Figure 2 and Figure 8As shown, the first key device includes a seesaw key 7, the upper surface of the seesaw key 7 forms a V-shaped symmetrical structure with an obtuse angle, the middle parts of the two side surfaces of the seesaw key are respectively connected to a rotating shaft, and the rotating shaft is inserted into the hole on the shell to realize the swing of the seesaw key, and the middle part of the lower surface of the seesaw key 7 is fixed with a connecting pipe 701, and the on-off component includes a movable push rod 703, one end of the movable push rod 703, that is, the upper end, is connected to a push rod spring 702, and the other end of the push rod spring 702 is arranged in a groove of the connecting pipe 701 on the lower side of the seesaw key 7, and the movable push rod 703 is connected to the upper end. The other end of the top rod 703, i.e., the lower end, cooperates with the moving contact assembly 704. The moving contact assembly 704 and the static contact are installed in the inner base 3. Specifically, the moving contact assembly 704 includes a copper plate with a downwardly bent concave middle portion, and two contact surfaces 7041 are formed on both sides of the concave area. The lower surfaces of the two side wings of the copper plate are welded or integrally formed with moving contacts 7042. The concave portion in the middle of the copper plate is provided with a limit groove 7043 in the horizontal direction. The limit groove 7043 cooperates with a limit bar, and the limit bar is connected to the PCB board 2 and its circuit. When the moving contact contacts any static contact, a conductive path can be formed to turn on the corresponding light source. The other end of the movable top rod 703, i.e., the lower end, is arranged in the middle position of the two contact surfaces 7041. The movable top rod is pressed on the copper plate of the moving contact assembly under the action of the spring. The action force cooperates with the limit groove and the limit strip to limit the position of the copper plate. At the same time, the reaction force acts on the seesaw button. When the seesaw button swings to one side, the seesaw button can be stably kept in this state. When one side surface of the seesaw button 7 is pressed, the seesaw button 7 swings, and the corresponding movable top rod 703 swings to the other side and acts on the corresponding contact surface 7041, so that the corresponding moving contact 7042 on the moving contact assembly 704 is closed in contact with the static contact, and the circuit is turned on. This embodiment can control the on and off of two light sources, and the dimming component can control the illuminance of the corresponding on and off light sources.
