The side wall of the lamp barrel 3 is provided with a convection hole 35 for air to pass through, and the position of the convection hole 35 is close to the position of the ultraviolet lamp 34. The air is naturally convected through the convection hole 35 and then irradiated with ultraviolet rays by the ultraviolet lamp 34, and the air is sterilized and disinfected by the ultraviolet rays. Preferably, a device (such as a fan) for increasing the convection velocity of air can be correspondingly arranged at a proper position of the track lamp, so that the air can forcibly flow according to a set path and direction, and the track lamp can further ensure that the track lamp can kill bacteria and viruses in the air.

The opening and closing of the light source 32 and the ultraviolet lamp 34 are independently controlled, that is, only the light source 32, only the ultraviolet lamp 34 or both the light source 32 and the ultraviolet lamp 34 can be turned on, and a controller and a circuit board for controlling the turning on or off of the light source 32 and the ultraviolet lamp 34 are arranged in the guide rail. The suspension arm 2 is a hollow structure with two ends communicated with each other, so that electric wires can enter the lamp barrel 3 from the guide rail box 1 through the suspension arm 2 to be connected with the light source 32 and the ultraviolet lamp 34. The light source 32 and the ultraviolet lamp 34 can be turned on or off by adopting a remote control delay switch control mode, a human body infrared induction delay switch control mode or a combination mode of the remote control delay switch control mode and the human body infrared induction delay switch control mode, wherein the remote control delay switch control mode is mainly characterized in that a power supply is switched on through a manual remote control switch to supply power to a circuit, and after a certain time (which can be set), the power supply is automatically cut off to stop supplying power to the circuit; the human body infrared induction time delay switch control detects a human body by arranging an infrared sensor, and controls a power supply to supply power to a circuit.

Further, as shown in fig. 4 to 7, the zoom assembly 4 includes a zoom lens 41, a focus ring 42 and a guide ring 43 which are nested and mounted in sequence from inside to outside; the edge of the zoom lens 41 is provided with a protrusion 411 protruding outward; a spiral groove 421 corresponding to the protrusion 411 is formed in the wall of the focus ring 42, and the zoom lens 41 is engaged with the spiral groove 421 through the protrusion 411; a vertical guide groove 431 is formed in the inner side of the guide ring 43; the protrusion 411 at least includes a long protrusion 4111, and the long protrusion 4111 penetrates through the corresponding spiral groove 421 and extends into the guide groove 431, so that the zoom lens 41 can only slide up and down along the guide groove 431.

The zoom lens 41 is arranged in the guide ring 43, the protrusion 411 is located in the spiral groove 421, the protrusion 411 can slide in the spiral groove 421, and the focus ring 42 is rotated to enable the protrusion 411 to slide in the spiral groove 421, so that the zoom lens 41 can move up and down in the focus ring 42. Since the zoom lens 41 functions to move away from or close to the lamp source to perform the focusing function of the lamp, the zoom lens 413 should be restricted from rotating with the focus ring 42. Although the inner wall of the spiral groove 421 will abut against the protrusion 411 when the focus ring 42 rotates, so as to move the zoom lens 41 up and down, it may also happen that the zoom lens 41 rotates along with the focus ring 42 and cannot move up and down accurately, in order to avoid this situation, and ensure that the zoom assembly 4 can focus the lamp accurately, a vertical guide groove 431 is provided on the inner wall of the guide ring 43, the guide groove 431 is provided to extend outward from the inner wall of the guide ring 43, the long protrusion 4111 passes through the corresponding spiral groove 421 and extends into the guide groove 431, and the guide groove 431 is used to limit the lateral movement of the long protrusion 4111, so that the long protrusion 4111 can only slide up and down along the guide groove 431.

The guide groove 431 is arranged to limit the lateral movement of the long protrusion 4111, so that the situation that the zoom lens 41 rotates along with the rotation of the focusing ring 42 is avoided, the zoom lens 41 can only move up and down relative to the focusing ring 42 is ensured, and the zoom assembly 4 is ensured to normally realize a focusing function.

The guide ring 43 is sleeved on the focusing ring 42, when in use, the guide ring 43 is fixed on the lamp tube 3, and the focusing ring 42 can rotate relative to the guide ring 43, so that when in focusing, the focusing ring 42 is rotated clockwise or anticlockwise to enable the zoom lens 41 to move up and down in the focusing ring 42 and the guide ring 43, so that the distance between the zoom lens 41 and a lamp source is increased or decreased, and further the focusing is realized. The arrangement of the focusing assembly can realize the zooming of the guide rail lamp, and the zooming assembly 4 has compact structure and strong focal length adjustment stability.

Further, the width of the spiral groove 421 is larger than the width of the protrusion 411.

When the zoom lens 41 is assembled on the focusing ring 42, the protrusion 411 is arranged in the spiral groove 421, the width of the spiral groove 421 is larger than that of the protrusion 411, so that the zoom lens 41 is assembled on the focusing ring 42 conveniently, and the protrusion 411 slides more smoothly in the spiral groove 421 and cannot be clamped in the spiral groove 421 to cause the problem of incapability of sliding.

Further, as shown in fig. 4 to 5, one end of the focusing ring 42 close to the light source 32 is provided with a first buckling part 422 connected with the guide ring 43.

When the focus ring 42 and the guide ring 43 are assembled together, the first fastening portion 422 hooks the end of the guide ring 43 close to the light source, so as to connect the two firmly, but the first fastening portion 422 is not fixed with the guide ring 43, so that the rotation of the focus ring 42 relative to the guide ring 43 is not affected. More preferably, the number of the first fastening parts 422 is three, and the first fastening parts 422 are uniformly distributed on the focusing ring 42. Three first buckling parts 422 are uniformly distributed, so that the guide ring 43 and the focusing ring 42 are connected more stably.

When the zoom assembly 4 is used, it needs to be fixed to the lamp tube 3, specifically, the guide ring 43 is fixed to the lamp tube 3. When the zoom lens is used, the zoom component 4 is detachably buckled on the lamp tube 3, the second buckling part 4323 plays a buckling role and is abutted on the inner wall of the lamp tube 3, so that the zoom component 4 is fixed on the lamp tube 3, and the second buckling part 432 facilitates the assembly and disassembly of the zoom component 4.

More preferably, the number of the second buckling parts 432 is three, and the second buckling parts are uniformly distributed on the guide ring 43. The three second buckling parts 432 are arranged, so that the zoom component 4 and the lamp barrel 3 are more stably connected and are not easy to fall off in the using process.

Further, a rear cover 5 is further disposed on the lamp cylinder 3, and the rear cover 5 is located on a side far away from the light source 32; the rear cover 5 is provided with a groove 51, and the side wall of the groove 51 is provided with a first threaded hole 511; the suspension arm 2 is provided with a second threaded hole 21 matched with the first threaded hole 511, and a bolt 6 fixedly connects the suspension arm 2 and the rear cover 5 through the first threaded hole 511 and the second threaded hole 21.
