It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as the meaning in the context of the prior art, and will not be interpreted with idealized or overly formal meanings unless specifically defined as here.

[0028] In one embodiment of the present invention, reference Figure 1-3, a light source device 100 is provided, including a housing 10 , a lens assembly 20 disposed in the housing 10 , and a light emitting assembly 30 placed above the lens assembly 20 .

[0029] Here, the housing 10 can be a metal housing or a plastic housing. The advantages of the metal housing are high rigidity and strength, and the metal housing has a good effect on the heat dissipation of the light source device. The plastic housing is lighter and can greatly reduce the weight of the entire light source device. The housing 10 can be formed by, for example, stamping, casting or injection molding, and the utility model does not limit this. The housing 10 is used to provide a storage and installation space for the remaining components of the light source device 100.

[0030] Here, the lens assembly 20 is used to focus the light emitted by the light emitting assembly 30, thereby changing the light properties and improving the light brightness and focusing degree. The light emitting assembly 30 is used to emit light, and it can be various types of light emitting assemblies, such as traditional halogen lamps, incandescent lamps, or more energy-saving and environmentally friendly LED lamps. The technical solution is not limited thereto.

[0031] In addition, the light source device 100 further includes an adjustment component for adjusting the distance of the lens assembly 20 relative to the light emitting assembly 30, and the adjustment component includes: a first driving member 26 fixedly mounted on the lens assembly 20 and a second driving member 38 fixedly mounted on the light emitting assembly 30, wherein the first driving member 26 and the second driving member 38 are meshed with each other. For example, the first driving member 26 may be a rack 26, and the second driving member 30 may be a gear 38. By meshing the rack 26 and the gear 38 with each other, the user can generate relative movement between the gear 38 and the rack 26 by rotating the gear 38, so that when the gear 38 is set to be only rotatable, the rotation of the gear 38 causes the rack 26 meshed therewith to move, and the lens assembly 20 fixed to the rack 26 also moves synchronously, thereby adjusting the height / elevation angle of the lens assembly 20.

[0032] In one embodiment, the lens assembly 20 includes a plate body 22, on which the rack 26 is mounted; the light emitting assembly 30 includes a lamp housing 32, on which the gear 38 is rotatably mounted. The plate body 22 is used as a basic component of the entire lens assembly 20, and is used to mount the rack 26 thereon, so that the rack 26 and the gear 38 can be meshed and operated more stably. In addition, the plate body 22 is also used to mount the lens thereon. The side wall of the lamp housing 32 is used to rotatably mount the gear 38, so that when the gear 38 rotates, the rack 26 can be moved up and down by meshing, thereby changing the up and down position of the entire lens assembly 20, that is, the posture or elevation angle.

[0033] Preferably, in order to achieve smooth matching and installation between the lens assembly 20 and the light emitting assembly 30, a guide rod 28 may be provided on the upper surface of the plate body 22; a guide groove 324 may be provided on the bottom wall of the lamp housing 32; and the guide rod 28 is inserted into the guide groove 324. Through the sliding action of the guide rod 28 in the guide groove 324 and the orientation guiding action of the guide groove 324 on the guide rod 28, the lens assembly 20 and the light emitting assembly 30 may be assembled smoothly and accurately.

[0034] As for the mounting structure of the gear 38, it can have many different forms. For example, in one embodiment, the side wall of the lamp housing 32 is provided with an axial hole 322, and the gear 38 has a gear shaft 382, ​​and the gear shaft 382 is rotatably disposed in the axial hole 322. In other words, the rotation of the gear 38 relative to the lamp housing 32 is achieved by the gear shaft 382 being inserted into the axial hole 322 and rotating relative to the axial hole 322.

[0035] Optionally, the adjustment component may further include a knob 31, which is fixed on the end surface of the gear 38 and is configured to rotate synchronously with the gear 38. The knob 31 is configured to facilitate the user to easily rotate the gear 38. Since the circumferential end surface of the knob 31 has friction lines, such as friction lines arranged obliquely, when the user turns the friction lines, the knob 31 starts to rotate, and the gear 38 fixed and rotating synchronously with the knob 31 also rotates together.

[0036] Furthermore, the knob 31 has a knob wheel 312 and a shaft 314 at the end of the knob wheel 312, and the shaft 314 is inserted into the end surface of the gear 38 in a non-rotatable manner. With the shaft 314 tightly inserted into the end surface of the gear 38, a fixed connection between the knob 31 and the gear 38 is achieved. Although in this embodiment, the knob 31 and the gear 38 are fixed by the shaft 314 tightly fitting with the gear end surface, the utility model is not limited thereto. For example, in another embodiment, the two can be fixed by various methods such as snap or threaded connection or welding.

[0037] Preferably, in one embodiment, a knob hole 16 is provided on the side wall of the housing 10; the shaft 314 of the knob 31 passes through the knob hole 16 and is inserted into the end surface of the gear 38. With this arrangement, the knob 31 can be exposed from the outside of the housing 10, so that the knob 31 can be easily turned from the outside of the housing 10.

[0038] Preferably, a lens 24 is provided on the plate body 22; a lens hole 12 is provided at the bottom of the housing 10; and the lens 24 is provided in the lens hole 12. The lens 24 can focus the light emitted by the light-emitting component 30, thereby forming light with higher intensity and brightness to achieve a lighting effect. The lens hole 12 can protect the lens 24 and prevent the lens 24 from being hit by an external object and causing it to break. In addition, the lens hole 12 can prevent the light projected from the lens 24 from leaking out from the side of the lens 24, thereby causing light pollution to the user and damaging the user's eyes.

[0039] In one embodiment, the light-emitting component 30 also includes a printed circuit board 34 placed at the bottom of the lamp housing 32, a light source 342 is arranged on the bottom surface of the printed circuit board 34, and a sealing rubber ring 344 surrounding the light source 342 is coated on the bottom surface of the printed circuit board 34, and the sealing rubber ring 344 is in contact with the board body 22. The printed circuit board 34 is used to perform various controls on the light source 342, such as controlling its brightness, switching and frequency, and also various controls on its color. The purpose of setting the sealing rubber ring 344 is to provide a waterproof and dustproof effect for the light source 342, to prevent water vapor or dust from entering the surface of the light source 342, thereby affecting the light-emitting effect. Here, it should be noted that the light source 342 can be various types of light sources, as described above.

[0040] In one embodiment, the light source device 100 further includes a bottom cover 40, which is fixed to the shell 10. A first wire groove 14 is provided on the side wall of the shell 10; a second wire groove 329 is provided on the side wall of the lamp housing 32; and wires pass through the two wire grooves. The wires electrically connect the printed circuit board 34 with external devices such as a power supply, so that the printed circuit board 34 can operate normally. Preferably, a glue injection hole can be provided on the bottom cover 40 so that the electronic components in the shell 10 can be encapsulated with a sealant to achieve a waterproof effect. Specifically, when the electronic components in the shell 10 are assembled, an external glue injection device injects glue into the interior of the shell 10 through the glue injection hole, and covers the surface of the electronic components to solidify, thereby achieving a waterproof effect.

[0041] In summary, in the light source device provided by the present invention, the light source device also includes an adjustment component for adjusting the distance of the lens assembly relative to the light-emitting assembly, and the adjustment component includes: a first driving component fixed on the lens assembly and a second driving component fixed on the light-emitting assembly, the first driving component and the second driving component are engaged with each other, and through the engagement between the two driving components, the user can easily, quickly and accurately adjust the position of the lens assembly.
