[0026] In order to make the present invention more clearly understood, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0027] The utility model provides an integrated wireless dimming and color-adjusting LED zoom track spotlight, which can change the color temperature, brightness and angle of the light, such as Figure 3 , Figure 4 As shown, it includes a front ring 1, a lens 2, a pressure ring 3, a stretching bracket 4, a bolt 5, a light source bracket 6, a light source 7, a lamp tube 8, a rear cover 9, a connecting rod 10, a power box with a track head, a Bluetooth dimming module 12, a power module 13, a rotating shaft 15 with a hand-breaking block, and a barrier 16. The Bluetooth dimming module 12, the power module 13, the rotating shaft 15 with a hand-breaking block, and the light source 7 are connected by a wire.

[0028] A rotating shaft 15 with a hand-breaking block is provided at one end of the power box with a track head, and a power module 13, a barrier 16 and a Bluetooth dimming module 12 are provided in the power box with a track head. The power box with a track head includes a power box housing 11 and a power box cover 14, and the power box cover 14 is fixed to the power box housing 11 by bolts 5. The Bluetooth dimming module 12 is fixed by a self-contained buckle in the power box housing 11 and is located at the bottom of the power box housing 11. The power module 13 is fixed above the Bluetooth dimming module 12 by a self-contained buckle in the power box housing 11. The barrier 16 is fixed between the power module 13 and the Bluetooth dimming module 12 by a self-contained buckle in the power box housing 11 to prevent the power module 13 from contacting the Bluetooth dimming module 12 and generating signal interference.

[0029] The bottom of the power box housing 11 is connected to the connecting rod 10 by bolts 5, the connecting rod 10 and the lamp tube 8 are connected and locked by bolts 5, the back cover 9 is connected and locked by bolts 5, the inner side of the lamp tube 8 is provided with a light source 7, the bottom of the light source 7 is coated with heat dissipation paste to dissipate the heat of the light source 7 during assembly, and the front end of the light source 7 is provided with a light source bracket 6; the light source bracket 6 is fixed to the lamp tube 8 by bolts 5, so that the light source 7 is limited in the lamp tube 8, and the front end of the light source bracket 6 is provided with a pressing ring 3, and the pressing ring 3 is fixed to the inner side of the lamp tube 8 by bolts 5. The inner wall of the pressing ring 3 is provided with a stretching bracket 4, the bottom of the stretching bracket 4 has a self-contained step and the self-contained step on the top of the pressing ring 3 is abutted and limited when the stretching bracket 4 is pulled and pulled, and a certain gap is provided between the light source bracket 6 and the pressing ring 3, so that the stretching bracket 4 can be stretched, and the front end of the stretching bracket 4 is provided with a lens 2, which is placed on the self-contained step of the stretching bracket 4, and the front end of the lens 2 is provided with a front ring 1, which is tightened with the external thread of the stretching bracket 4 through the internal thread, so as to fix the lens 2 and ensure that the lens 2 will not shake at will.

[0030] The utility model realizes the change of the angle of the lamp body by the cooperation of the front ring 1, the lens 2 and the stretching bracket 4 (pulling the stretching bracket 4 can change the distance between the lens 2 and the light source 7 to realize the change of the angle). The power box with a built-in power source cooperates with the track head to realize the integration of the track head and the power box, the volume of the lamp body becomes smaller, and the rotating shaft 15 with the hand-breaking block can be turned to energize the track.

[0031] like Figure 1 As shown, the Bluetooth dimming module 12 in the utility model is provided with a Bluetooth control unit, which includes a voltage stabilizer, a Bluetooth module device that can receive dimming instructions from an external control device, a main controller that converts the dimming signal of the Bluetooth module device into a dimming instruction, and a relay that ensures that the Bluetooth control unit will not be burned when overloaded. One end of the voltage stabilizer is connected to one end of the Bluetooth module device, and the other end is connected to the input power end of the track head (i.e., the power module 13). The other end of the Bluetooth module device is connected to one end of the main controller, and the other end of the main controller is connected to the light source chip (i.e., the light source 7). A relay is connected in parallel between the voltage stabilizer and the main controller. The power module 13 includes a transformer, a rectifier, a filter, and a capacitor connected in sequence. The other end of the transformer is connected to an external AC power supply, and the other end of the capacitor is connected to the other end of the voltage stabilizer. The Bluetooth dimming module 12 and the power module 13 are both arranged on a PCB board.

[0032] The working principle of the utility model is:

[0033] The input end of the driver is connected to conventional AC power. After passing through the internal transformer, the AC power is converted into the voltage required by the PCB board. The voltage in the circuit is converted into DC power after passing through the rectifier device. Because the DC power converted by the rectifier will have certain clutter and noise, a filter is added to the conversion current to filter out the clutter and noise in the power supply. The filtered current passes through the capacitor, which will store the electrical energy in the circuit and the voltage after smooth conversion.

[0034] The power supply in the drive converts the smooth voltage into the required constant voltage through the voltage regulator on the power module 13 to power the Bluetooth module device, and also powers the relay device; after receiving the dimming instruction from the boundary couplet device, the Bluetooth module device will transmit the dimming demand to the main controller. The main controller uses PWM (pulse width modulation) technology through internal logic operation to change the average current in the lamp bead circuit through rapid switching control, thereby achieving a dimming effect.

[0035] like Figure 2As shown, the light source 7 built into the lamp of the utility model is a dual-color temperature light source, that is, two light sources with different color temperatures. A packaging substrate will encapsulate a warm light lamp bead with a color temperature of 1800K, and at the same time, another cold light lamp bead with a color temperature of 6500K will be encapsulated. The port of the substrate will leave corresponding conductive electrodes because of the column feet of the lamp beads, and the conductive electrodes will be welded to the outlet wires of the track head later. When the Bluetooth chip (i.e., the Bluetooth module device) receives the dimming instruction and gives it to the control chip (i.e., the main controller), the control chip controls the brightness of the lamp beads by controlling the relative voltage of the column feet of different color temperatures, and then realizes the mixed color light emission of the lamp beads. By controlling the brightness and color temperature of different LEDs, the color temperature of the light emitted by the light source can be changed.
