A polarized lens combined linear light projecting lamp device

Abstract

This utility model discloses a linear floodlight device with a polarizing lens combination, relating to the field of LED lighting technology. It includes an aluminum alloy housing and an injection-molded polarizing lens module. A partition is fixed inside the aluminum alloy housing, and a light source aluminum substrate assembly is connected to the top of the partition. The injection-molded polarizing lens module is disposed on top of the light source aluminum substrate assembly and includes a mounting plate, a first lens, a second lens, and a through hole. Through the setting of the injection-molded polarizing lens module, when the light source aluminum substrate assembly is working, some of the light emitted by the light source passes through the mounting plate. At this time, the turtle-back shaped first lens deflects and controls the light, initially expanding the polarization range. Simultaneously, some light passes through the second lens, further deflecting the light, ultimately causing some light to be emitted at an angle exceeding 65 degrees, achieving large-angle polarization.

Description

Technical Field

[0001] This utility model relates to the field of LED application lighting technology, specifically a linear floodlight device with a polarizing lens combination. Background Technology

[0002] As an important lighting device, floodlights are widely used in large-area work sites such as squares, stadiums, building facades, and roads. Their core function is to project light onto specific areas to achieve precise lighting.

[0003] Traditional floodlight optical systems often employ a symmetrical light distribution design, where the emitted light rays are symmetrically distributed along the optical axis of the lens, forming symmetrical light spots (such as circles or grooves). However, in practical applications, the polarization angle is usually small, making it difficult to achieve large-angle light deflection, which leads to a limited illumination range. Utility Model Content

[0004] The purpose of this invention is to provide a linear floodlight device with a polarizing lens combination to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a linear floodlight device with a polarizing lens combination, comprising an aluminum alloy housing and an injection-molded polarizing lens module. A partition is fixed inside the aluminum alloy housing, and a light source aluminum substrate assembly is connected to the top of the partition. The injection-molded polarizing lens module is disposed on top of the light source aluminum substrate assembly, and includes a mounting plate, a first lens, a second lens, and a through hole. The mounting plate is disposed on the top of the light source aluminum substrate assembly, and the first lens is fixed to the top of the mounting plate. A second lens is disposed on one side of the first lens. A through hole is formed in the middle of the mounting plate, and a positioning hole is formed on the top of the light source aluminum substrate assembly.

[0006] Furthermore, the first lens is turtle-back shaped, and the first lens corresponds one-to-one with the light source chip on the light source aluminum substrate assembly.

[0007] Furthermore, the second lens is cylindrical, and the interior of the second lens is connected to the interior of the first lens.

[0008] Furthermore, the positioning holes correspond one-to-one with the through holes, and the positioning holes are equidistantly distributed along the top of the light source aluminum substrate assembly.

[0009] Furthermore, tempered glass is fitted and bonded to the top of the aluminum alloy housing, and a power driver is installed at the lower interior of the aluminum alloy housing.

[0010] Furthermore, end caps are provided on both sides of the aluminum alloy shell, and an installation hole is provided on one side of the end cap.

[0011] Furthermore, the partition plate has connection holes at both ends, and the connection holes correspond one-to-one with the mounting holes.

[0012] Furthermore, a stainless steel bolt is threaded into the middle of the end cap plug, and a mounting bracket is abutted against one side of the end cap plug.

[0013] This utility model provides a linear floodlight device with a polarizing lens combination, which has the following beneficial effects: 1. This utility model, through the setting of the injection-molded polarizing lens module, when the light source aluminum substrate assembly is working, part of the light emitted by the light source will pass through the mounting plate and be emitted. At this time, the first lens with a turtle-back shape is used to deflect and control the light, initially expanding the polarization range. At the same time, part of the light will be emitted through the second lens, which can further deflect the light, and finally make part of the light emit at an angle of more than 65 degrees, realizing large-angle polarization, thereby expanding the illumination range of the floodlight; 2. The present invention, through the setting of through holes and positioning holes, facilitates the installation of injection-molded polarizing lens modules on the light source aluminum substrate assembly using fastening bolts. At the same time, multiple sets of injection-molded polarizing lens modules are provided. Therefore, when some LED light source chips on the light source aluminum substrate assembly are damaged, only the corresponding injection-molded polarizing lens module needs to be removed for repair, without the need for complete disassembly, thereby improving the efficiency of maintenance.

[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0017] like Figure 1 and Figure 2As shown, a linear floodlight device with a polarizing lens combination includes an aluminum alloy housing 1 and an injection-molded polarizing lens module 4. A partition 2 is fixed inside the aluminum alloy housing 1, and a light source aluminum substrate assembly 3 is connected to the top of the partition 2. The injection-molded polarizing lens module 4 is disposed on top of the light source aluminum substrate assembly 3, and includes a mounting plate 401, a first lens 402, a second lens 403, and a through hole 404. The mounting plate 401 is disposed on the top of the light source aluminum substrate assembly 3, and the first lens 402 is fixed to the top of the mounting plate 401. The second lens 403 is disposed on one side of the first lens 402. The first lens 402 is turtle-back shaped, and each first lens 402 corresponds one-to-one with a light source chip on the light source aluminum substrate assembly 3. Part of the light emitted by the light source will... When the light beam passes through the mounting plate 401, the first lens 402, which is shaped like a turtle's back, deflects and controls the light, initially expanding the polarization range. The second lens 403 is cylindrical, and its interior is connected to the interior of the first lens 402. Some light beams will pass through the second lens 403, which can further deflect the light beams, ultimately causing some light beams to be emitted at an angle of more than 65 degrees, achieving large-angle polarization. A through hole 404 is provided in the middle of the mounting plate 401, and a positioning hole 405 is provided on the top of the light source aluminum substrate assembly 3. The positioning hole 405 corresponds one-to-one with the through hole 404, and the positioning holes 405 are evenly distributed along the top of the light source aluminum substrate assembly 3, which facilitates the installation of the injection-molded polarizing lens module 4 on the light source aluminum substrate assembly 3 using fastening bolts.

[0018] like Figure 2 and Figure 3 As shown, tempered glass 5 is embedded and bonded to the top of the aluminum alloy housing 1, and a power driver 6 is installed at the lower end of the interior of the aluminum alloy housing 1. The tempered glass 5 protects the top of the aluminum alloy housing 1. The power driver 6 can supply power to the light source chip on the light source aluminum substrate assembly 3. End caps 7 are provided on both sides of the aluminum alloy housing 1, and a mounting hole 8 is opened on one side of the end cap 7. The end caps 7 are used to seal both sides of the aluminum alloy housing 1. Connection holes 9 are opened at both ends of the partition 2, and the connection holes 9 correspond one-to-one with the mounting holes 8, so that fasteners can be passed through the connection holes 9 and locked to the mounting holes 8 to fix the end caps 7 to both sides of the aluminum alloy housing 1. A stainless steel bolt 10 is threadedly connected to the middle of the end cap 7, and a mounting bracket 11 is abutted on one side of the end cap 7. The mounting bracket 11 is easily fixed to one side of the end cap 7 by the stainless steel bolt 10.

[0019] In summary, when using this polarizing lens combined with a linear floodlight device, firstly according to... Figure 1 , Figure 2 and Figure 3The structure shown in the diagram, during assembly, uses bolts passing through the through holes 404 on the mounting plate 401 and threadedly connected to the positioning holes 405 on the light source aluminum substrate assembly 3 to install the injection-molded polarizing lens module 4 onto the light source aluminum substrate assembly 3. Then, tempered glass 5 is bonded to the top of the aluminum alloy housing 1. Subsequently, fasteners passing through the connecting holes 9 and threadedly connected to the mounting holes 8 are used to fix the end cap 7 to both sides of the aluminum alloy housing 1. Then, stainless steel bolts 10 are used to fix the mounting bracket 11 to one side of the end cap 7, thereby realizing the assembly operation of the lamp. Finally, when the light source aluminum substrate assembly 3 is working, some of the light emitted by the light source will pass through the mounting plate 401 and be emitted. At this time, the first lens 402 with a turtle-back shape is used to deflect and control the light, initially expanding the polarization range. At the same time, some light will be emitted through the second lens 403, which can further deflect the light, ultimately making some of the light emitted at an angle of more than 65 degrees, realizing large-angle polarization, thereby expanding the illumination range of the floodlight.
