Description

Technical Field

[0001] The utility model belongs to the technical field of LED lens lamps, and particularly relates to a waterproof LED optical lens for outdoor use. Background Technique

[0002] As a new type of energy-saving LED lamp, LED floodlights have been widely used in indoor and outdoor lighting and building decorative lighting;

[0003] For example, an LED lens combination with the publication number CN208074887U includes a total reflection lens. A receiving cavity for receiving an LED light source is formed on the bottom surface of the total reflection lens. The cavity wall of the receiving cavity forms an incident surface. A total reflection surface is arranged around the bottom surface on the side surface of the total reflection lens. The top surface of the total reflection lens is an inner exit surface. The LED lens combination further includes a fly-eye lens covering the inner exit surface of the total reflection lens. The top surface of the fly-eye lens is an outer exit surface, and the outer exit surface is formed by densely arranging and connecting a plurality of arc-shaped protrusions; the LED floodlight includes an LED light source and an LED lens combination covering the outer side surface of the LED light source. In the embodiment of the utility model, by covering the inner exit surface of the total reflection lens with a fly-eye lens with an outer exit surface formed by densely arranging and connecting a plurality of arc-shaped protrusions, the uniformity of the light spot is effectively improved, a rectangular light pattern in special applications of the LED floodlight is obtained, optical pollution is reduced, energy waste is reduced, and the light utilization rate is improved.

[0004] In the existing LED lens lamp, the edge of the lamp sleeve is flush with the edge of the main lamp body. Through the fitting between the lamp sleeve and the main lamp body and then fixing with fasteners, the lamp sleeve is installed on the main lamp body. When used outdoors, a sealing gasket can also be provided between the lamp sleeve and the main lamp body to achieve waterproofing, as Figure 9 shown;

[0005] However, due to the changeable outdoor environment, the service life cycle of the sealing gasket is very short, and it is easy to deform and crack. As a result, rainwater in the outdoor environment easily flows in from the gap between the lamp sleeve and the main lamp body, causing damage to the LED lens lamp;

[0006] In view of this, the utility model provides a waterproof LED optical lens for outdoor use to solve the above problems. Content of the Utility Model

[0007] (1) Technical Problems to be Solved

[0008] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a waterproof LED optical lens for outdoor use, which aims to solve the waterproof problem of LED lens lamps in the existing technology.

[0009] (2) Technical Solutions

[0010] To solve the above technical problems, the present utility model provides an outdoor waterproof LED optical lens, which includes a main lamp body. An LED lamp bead is provided inside the illumination end of the main lamp body. A lens fitting groove is provided at the opening of the illumination end of the main lamp body. A lens is embedded in the lens fitting groove. A lamp sleeve made of a transparent material is installed at the illumination end of the main lamp body. A rolled edge that curls inward is provided on the edge surface of the lamp sleeve. The edge length of the lamp sleeve is greater than the edge thickness of the opening of the illumination end of the main lamp body. A drain hole is opened at the bottom of the edge of the lamp sleeve.

[0011] When using the outdoor waterproof LED optical lens of this technical solution, when the lamp sleeve is installed at the illumination end of the main lamp body, due to the edge length of the lamp sleeve being greater than the edge thickness of the opening of the illumination end of the main lamp body and the rolled edge provided on the edge of the lamp sleeve, the edge of the lamp sleeve can wrap the edge of the illumination end of the main lamp body to form a shelter similar to an eaves. When rain falls on the main lamp body and the lamp sleeve, the edge of the lamp sleeve will prevent rainwater from directly falling into the gap between the lamp sleeve and the main lamp body. Thus, a good waterproof effect can be achieved without the need for a gasket. At the same time, through the opening of the drain hole, the rainwater that falls into the lamp sleeve can be discharged from the drain hole, further improving the waterproof effect.

[0012] Preferably, mounting holes arranged in a ring are opened on the opening surface of the illumination end of the main lamp body. A positioning post adapted to the mounting hole is connected inside the lamp sleeve. The surface of the positioning post is a threaded structure.

[0013] Furthermore, a gasket is adhered to the outer edge surface of the illumination end of the main lamp body. When the lamp sleeve covers the illumination end of the main lamp body, an interference fit connection is formed between the lamp sleeve and the main lamp body through the gasket.

[0014] Even further, the lamp sleeve and the main lamp body are in threaded connection.

[0015] Even further, a reflector is provided inside the illumination end of the main lamp body. The outer wall of the reflector is tangent to the inner wall of the illumination end of the main lamp body.

[0016] Even further, a magnet fitting groove is opened inside the illumination end of the main lamp body, and the magnet fitting groove surrounds the LED lamp bead. A magnet one is embedded inside the magnet fitting groove.

[0017] Even further, a magnet two capable of adsorbing to the magnet one is provided at one end of the reflector opposite to the magnet fitting groove. The reflector forms a magnetic adsorption connection with the main lamp body through the adsorption of the magnet one and the magnet two.

[0018] Even further, fixing bolts are provided on both sides of the main lamp body. A bracket is installed between the fixing bolts. A nut is also threadedly connected to the fixing bolts.

[0019] (3) Beneficial effects

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] 1. In the present utility model, by designing the edge length of the lamp sleeve to be greater than the edge thickness of the opening at the irradiation end of the main lamp body, and at the same time setting the edge of the lamp sleeve as a rolled edge structure that rolls inward and opening a drain port, when installing the lamp sleeve and the main lamp body, a good waterproof effect can be achieved without setting a gasket.

[0022] 2. The reflector, lens and lamp sleeve of the present utility model can all be disassembled and assembled independently with the main lamp body. Therefore, when any one of its components is damaged, it can be independently replaced, effectively reducing the use cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] Embodiment 1:

[0034] As Figures 1-7As shown in the figure, a waterproof LED optical lens for outdoor use, the waterproof LED optical lens for outdoor use includes a main lamp body 1. Fixed bolts 2 are provided on both sides of the main lamp body 1. A bracket 3 is installed between the fixed bolts 2. A nut 4 is also threadedly connected to the fixed bolts 2. The main lamp body 1 can realize the adjustment and fixation of the illumination angle on the bracket 3 through the torque between the nut 4 and the fixed bolts 2. An LED lamp bead 5 is provided inside the irradiation end of the main lamp body 1. A lens fitting groove 16 is provided at the opening of the irradiation end of the main lamp body 1. A lens 12 is embedded in the lens fitting groove 16. A lamp sleeve 13 made of a transparent material is installed at the irradiation end of the main lamp body 1. The edge surface of the lamp sleeve 13 is provided with a rolled-in edge. The edge length of the lamp sleeve 13 is greater than the edge thickness of the opening of the irradiation end of the main lamp body 1. A drain hole 15 is opened at the bottom of the edge of the lamp sleeve 13. Installation holes 7 arranged in a ring are opened on the opening surface of the irradiation end of the main lamp body 1. A positioning post 14 adapted to the installation holes 7 is connected inside the lamp sleeve 13. The surface of the positioning post 14 is a threaded structure.

[0035] During specific use: First, embed the lens 12 into the lens fitting groove 16, then cover the lamp sleeve 13 on the opening of the irradiation end of the main lamp body 1, and place the drain hole 15 at the bottommost position. At this time, the positioning posts 14 are inserted into the installation holes 7 one by one, and a locking cap threadedly connected to the positioning posts 14 is used for locking and fixing; when rainwater in the external environment falls on the surfaces of the main lamp body 1 and the lamp sleeve 13, under the action of the edge of the lamp sleeve 13 and the drain hole 15, the rainwater can be blocked and drained, thus effectively preventing the rainwater from falling into the connection gap between the lamp sleeve 13 and the main lamp body 1, achieving good waterproof performance.

[0036] In order to further improve the waterproof effect between the lamp sleeve 13 and the main lamp body 1, a sealing gasket 8 can be adhered to the outer edge surface of the irradiation end of the main lamp body 1. When the lamp sleeve 13 is covered and installed on the irradiation end of the main lamp body 1, the lamp sleeve 13 also forms an interference fit connection with the main lamp body 1 through the sealing gasket 8.

[0037] Embodiment Two:

[0038] The difference from Embodiment One is that the lamp sleeve 13 and the main lamp body 1 are directly connected by threads. As Figure 8 shown, this connection method can realize the rapid assembly between the lamp sleeve 13 and the main lamp body 1. Compared with Embodiment One, its assembly speed is faster, and the consumption of manpower during assembly can be effectively saved.

[0039] Specifically, in order to enhance illumination, reduce light loss and improve utilization rate, a reflector 10 can be provided inside the irradiation end of the main lamp body 1. The outer wall of the reflector 10 is tangent to the inner wall of the irradiation end of the main lamp body 1;

[0040] Further, in order to improve the stability of the placement of the reflector 10, a magnet fitting groove 6 can be opened in the irradiation end of the main lamp body 1, and the magnet fitting groove 6 is arranged around the LED lamp beads 5. A first magnet 9 is embedded inside the magnet fitting groove 6. One end of the reflector 10 opposite to the magnet fitting groove 6 is provided with a second magnet 11 that can be adsorbed to the first magnet 9. The reflector 10 forms a magnetic adsorption connection with the main lamp body 1 through the adsorption of the first magnet 9 and the second magnet 11;

[0041] During specific use, when the reflector 10 is placed inside the irradiation end of the main lamp body 1, the stability of the reflector 10 can be improved under the adsorption of the first magnet 9 and the second magnet 11, thereby effectively reducing the influence of external forces on it and preventing loosening.

[0042] The above features can be used in combination with the solutions of Embodiment 1 or Embodiment 2.

[0043] The above embodiments are the preferred implementation solutions 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.
