[0009] The recessed lamp capable of regulating light and color temperature can achieve the following effects. Via the above improvement, the brightness and the color temperature of the recessed lamp is adjustable, which can satisfy the different requirements of the light at different places, by different users, at different time, and the recessed lamp is functional and can be conveniently used. BRIEF DESCRIPTION OF THE DRAWINGS [0010] FIG. 1 is a structure schematic diagram of this invention; [0011] FIG. 2 is an exploded diagram of this invention; [0012] FIG. 3 is a circuit principle diagram of this invention. DETAILED DESCRIPTION OF THE INVENTION [0013] This invention is further described in detail with regard to the accompanying drawings. [0014] In FIG. 1, FIG.2, and FIG. 3, this invention provides a recessed lamp capable of regulating light and color temperature, including a shell 1 and a back cover 2 connected with each other. In the shell, an LED lamp panel 3 is electrically connected with a circuit board 4. Several warm white LED lamp beads and fluorescent white LED lamp beads are distributed on the LED lamp panel. A plug power cord 5 electrically connected with the circuit board passes through the back cover. A light-regulating module 6 is disposed on the circuit board, and is connected with a light-regulating knob 20, and the light-regulating knob is disposed outside of 2 the back cover. When the recessed lamp is on, the light-regulating knob is rotated to adjust the luminous flux of the LED lamp beads, and the brightness range can be adjusted from 5% to 100%. [0015] The circuit board is connected with a color-controlling panel 7, the color-controlling panel is connected with a toggle block 8, and the toggle block is also placed outside of the back cover. [0016] A memory module 9 for memorizing the last lighting state and a judging module 10 for determining whether the time difference of on-off states is greater than a predetermined value are disposed on the circuit board, and the judging module is connected with the memory module. [0017] There are three positions for the toggle block, the three positions are D position, T position, and W position, and the T position is in the middle. When the toggle block is at the D position, the fluorescent white LED lamp beads are on; when the toggle block is at the W position, the warm white LED lamp beads are on; when the toggle block is at the T position, when the time difference from the off state to the on state of the power switch is less than 1.5 seconds, the color temperature of the recessed lamp is switched between the fluorescent white and warm white, when the time difference from the off state to the on state of the power switch is greater than 3 seconds, the recessed lamp stores the color temperature before turning off the power, and the recessed lamp is reopened with the color temperature when closed. [0018] The inner wall of the shell is provided with PET reflecting sheeting 11, and a light diffusion panel 12 is disposed at one end of the shell away from the back cover. Through the reflecting sheeting and the light diffusion panel, the light illumination range and brightness of the LED lamp beads can be improved. [0019] The back cover 2 has a gap 13, a press button 14 is fastened to the gap, a through hole 15 allowing the plug power cord to pass through is formed between the press button and the back cover, and both sides of the inner wall corresponding to the through hole have tooth-like protrusions 16. [0020] A protrudent loop 17 is disposed at an upper end of the back cover with the same axle, the inner diameter of the protrudent loop is equal to the inner diameter of the upper end of the back cover, the outer diameter of the protrudent loop is smaller than the outer diameter of the upper end of the back cover, the protrudent loop has several fixed through holes 18, and the shell has several blocks matched with the fixed through holes at the inner wall of the lower end, 3 such that the shell and the back cover are fixed. [0021] In this embodiment, the shell is made of retardant PBT material, and a pair of plastic fastener 19 is correspondingly disposed at the outside of the shell. A silica gel sleeve sleeves the plastic fastener, to facilitate the fixing of the recessed lamp. 4
