[0002] Landscape lights are an indispensable part of modern landscapes. They not only have high ornamental value themselves, but also emphasize the coordination and unity of the landscape of art lights with the historical culture of the scenic area and the surrounding environment. Landscape lights use different shapes, different light colors and brightness to create landscapes. For example, the landscape lamp in the shape of a red lantern brings a festive atmosphere to the square, and the green coconut tree lamp creates a tropical style by the pool, and it has been widely applied to landscape places such as squares, residential areas, and public green spaces.

[0003] Existing landscape lights are all designed by using a condenser lens plus an LED light source, and sometimes multiple LED light sources are also used. During the process of the light source emitting to the lens, since two adjacent LED chips are relatively close and not separated, the emitted light is prone to mutual crosstalk phenomenon, and the use effect is not good.

Detailed implementation manners

[0025] This detailed implementation manner is a lens assembly of a condenser-type landscape projection lamp, and its structural schematic diagram is as Figures 1-6 shown. The lens assembly includes a mounting plate 1, a lens sheet, and a gland 2. A plurality of through holes 3 are formed in the mounting plate 1, a condenser tube 4 is installed in the through hole 3, the lens sheet is composed of a plurality of condenser lenses 5, the plurality of condenser lenses 5 are respectively installed on the upper surfaces of the plurality of condenser tubes 4, a plurality of limit holes 6 corresponding to the condenser lenses 5 are formed in the gland 2, and the front and rear ends of the gland 2 are fixedly connected to the mounting plate 1 through a limiting component 7.

[0026] As Figure 1 and Figure 3 shown: In this embodiment, the condenser tube 4 includes a conical tube 401 and a fixing ring 402. The fixing ring 402 is fixedly connected to the upper surface of the conical tube 401, and the fixing ring 402 and the conical tube 401 are integrally formed.

[0027] With such a setting, the light source is located inside the condenser tube 4, and the light rays emitted by the light source will irradiate onto the condenser lens 5 after passing through the independent condenser tube 4. The fixing ring 402 positions the condenser tube 4 installed in the through hole 3.

[0028] As Figure 1 and Figure 3 shown: In this embodiment, a positioning groove 501 corresponding to the fixing ring 402 is formed on the lower surface of the condenser lens 5, and the condenser lens 5 adopts a Fresnel lens.

[0029] With such a setting, the positioning grooves 501 at the bottoms of the plurality of condenser lenses 5 are sleeved on the fixing rings 402 of the condenser tubes 4, which is convenient for the positioning and installation of the condenser lenses 5.

[0030] As Figure 1 and Figure 6 shown: In this embodiment, the gland 2 forms a plurality of pressing rods 201 through the limit holes 6, and the pressing rods 201 are located between two adjacent condenser lenses 5.

[0031] In this way, the pressure bar 201 is set to press and fix between two adjacent condenser lenses 5, making the fixation between the condenser lens 5 and the mounting plate 1 more firm.

[0032] As Figure 1 and Figure 6 shown: In this embodiment, the upper surface of the condenser lens 5 is a convex surface, and the upper surface of the condenser lens 5 does not exceed the upper surface of the pressure bar 201.

[0033] In this way, the condenser lens 5 can be protected within the limit hole 6 to avoid damage to the condenser lens 5.

[0034] As Figure 2 and Figure 3 shown: In this embodiment, a plurality of positioning holes 202 are formed at the edge of the lower surface of the gland 2, and positioning posts 203 corresponding to the positioning holes 202 are fixedly connected to the upper surface of the mounting plate 1.

[0035] In this way, through the guidance of the positioning holes 202 and the positioning posts 203, the gland 2 is installed on the condenser lens 5, facilitating the positioning and installation of the condenser lens 5 and improving the overall assembly efficiency.

[0036] As Figure 4 and Figure 5 shown: In this embodiment, the limiting component 7 includes fixing seats 701 fixedly connected to the front and rear sides of the upper surface of the mounting plate 1. A clamping groove 702 is formed in the fixing seat 701. Pressure blocks 703 are slidably inserted into the front and rear sides of the gland 2. One end of the pressure block 703 is located inside the gland 2 and is fixedly connected to a limiting block 704. A clamping block 705 corresponding to the clamping groove 702 is fixedly connected to the bottom end of the limiting block 704. A spring 706 is sleeved on the outer surface of the pressure block 703 and between the gland 2 and the limiting block 704.

[0037] In this way, by pressing the pressure blocks 703 on the front and rear sides, the limiting block 704 and the clamping block 705 are driven to move and stretch the spring 706. Then, through the guidance of the positioning holes 202 and the positioning posts 203, the gland 2 is installed on the condenser lens 5. At this time, the pressure blocks 703 are released, and the restoring force of the spring 706 can drive the clamping block 705 to be clamped with the clamping groove 702, so that the condenser lens 5 is located within the limit hole 6, and the pressure bar 201 presses and fixes between two adjacent condenser lenses 5, facilitating the disassembly or replacement between the condenser lens 5 and the mounting plate 1.

[0038] Working principle: When in use, a plurality of condenser cylinders 4 are installed in the through holes 3, and then the positioning grooves 501 at the bottom ends of the plurality of condenser lenses 5 are sleeved on the fixing rings 402 of the condenser cylinders 4. Then, the pressing blocks 703 on the front and rear sides are pressed to drive the limiting blocks 704 and the clamping blocks 705 to move and stretch the springs 706. Then, through the guiding of the positioning holes 202 and the positioning posts 203, the gland 2 is installed on the condenser lens 5. At this time, the pressing blocks 703 are released, and the restoring force of the springs 706 can drive the clamping blocks 705 to be clamped with the clamping grooves 702, so that the condenser lens 5 is located in the limiting holes 6. The pressing rod 201 presses between two adjacent condenser lenses 5 for fixation. Since the condenser cylinders 4 and the condenser lenses 5 of the lens assembly are assembled by a plurality of parts, modular production can be realized, and the installation and disassembly are convenient, improving the assembly efficiency. Then, the lens assembly is installed inside the landscape projection lamp. At this time, the light source is located inside the condenser cylinder 4. The light rays emitted by the light source will irradiate on the condenser lens 5 after passing through the independent condenser cylinder 4, aggregating the light rays and reducing the degree of light dispersion. The condenser cylinder 4 can separate the light rays emitted by two adjacent light sources, reducing the occurrence of light crosstalk between two adjacent light sources, and making the light effect emitted by the entire projection lamp better.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiment is a preferred implementation scheme of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
