Description

Technical Field

[0001] This utility model relates to an optical structure with replaceable optical components. Background Technology

[0002] In traditional lighting fixtures, anti-glare measures are typically achieved by stacking reflectors and anti-glare shields. However, in less demanding applications, anti-glare shields are unnecessary. Furthermore, the principle of anti-glare is based on increasing the overall depth of the lighting fixture; the deeper the anti-glare shield, the better the anti-glare effect. Therefore, in existing lighting fixtures, because the lamp housing dimensions are fixed and the depth cannot be altered, the only option after production is to match the reflector or a combination of reflector and anti-glare shield to the manufactured lamp housing. This lack of flexibility in customization based on specific usage requirements necessitates further improvement. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an optical structure with replaceable optical components.

[0004] An optical structure with replaceable optical components designed for this purpose includes a lamp housing, a lamp plate disposed inside the lamp housing, an optical module disposed on the lamp plate, the lamp housing being hollow inside with openings at both the top and bottom, a light-transmitting plate mounted on the lamp housing, a movable plate disposed in the lower inner part of the lamp housing, the movable plate being movable up and down relative to the lamp housing, the lamp plate and the optical module moving up and down with the movable plate, and a connecting positioning component fixedly connected to the lamp housing disposed on the lamp plate.

[0005] Compared with existing technologies, this invention features a movable plate located inside the lower part of the lamp housing. This movable plate moves vertically relative to the lamp housing, and the lamp plate and optical module move vertically along with it. The lamp plate is equipped with a connecting and positioning component fixedly connected to the lamp housing. By adjusting the vertical position of the movable plate, this invention changes the distance between the movable plate and the light-transmitting plate, thereby altering the installation space for the optical module to accommodate the assembly of different optical modules.

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0011] See Figures 1-4 An optical structure with replaceable optical components includes a lamp housing 10, a lamp plate 50 disposed inside the lamp housing 10, and an optical module 90 disposed on the lamp plate 50. The lamp housing 10 is hollow inside and open at both the top and bottom. A light-transmitting plate 20 is mounted on the lamp housing 10. A movable plate 40 is disposed in the lower inner part of the lamp housing 10. The movable plate 40 is vertically movable relative to the lamp housing 10. The lamp plate 50 and the optical module 90 move vertically with the movable plate 40. A connecting and positioning component 80 is disposed on the lamp plate 50 and fixedly connected to the lamp housing 10. This invention, by using a movable plate, can change the distance between the movable plate and the light-transmitting plate when adjusting the vertical position of the movable plate, thereby changing the installation space of the optical module to accommodate the assembly of different optical modules.

[0012] See Figure 3 The connecting positioning component 80 includes deformable parts 810 respectively disposed on the left and right sides of the movable plate 40. The deformable parts 810 are attached to the left and right inner walls of the lamp housing 10. Arc-shaped positioning ribs 820 are provided on the wall surface of the deformable parts 810 facing the inner wall of the lamp housing 10. Multiple arc-shaped positioning grooves 100 are arranged longitudinally on the left and right inner walls of the lamp housing 10. The arc-shaped positioning ribs 820 are movably inserted into any one of the arc-shaped positioning grooves 100.

[0013] This utility model uses longitudinally arranged arc-shaped positioning grooves 100. When the moving plate 40 moves up and down, the arc-shaped positioning ribs 820 are sequentially inserted into the arc-shaped positioning grooves 100 along the moving direction of the moving plate 40, so as to fix the position of the moving plate 40.

[0014] See Figure 3 The lower end of the deformable part 810 is provided with a gripping drive member 830. The function of the gripping drive member 830 is to cause the deformable part 810 to deform relative to the moving plate 40 when the gripping drive member 830 is pulled, so that the arc-shaped positioning rib 820 disengages from the arc-shaped positioning groove 100, so that the moving plate 40 can quickly move relative to the lamp housing 10 to the required position.

[0015] See Figure 2 The lower end face of the movable plate 40 is provided with a connecting seat 410, and the connecting seat 410 is connected to the inner wall of the lamp housing 10 by a self-tapping screw.

[0016] See Figure 2 and Figure 4 The optical module 90 includes a first connecting plate 60, the first connecting plate 60 is provided with a reflector 70 corresponding to the LED lamp core 510, the first connecting plate 60 is provided with a light inlet 610 communicating with the reflector 70, the LED lamp core 510 is located in the light inlet 610, the first connecting plate 60 is fixedly connected to the lamp board 50, and the lamp board 50 is fixedly connected to the movable plate 40.

[0017] See Figure 2 and Figure 4 The optical module 90 also includes an anti-glare mounting plate 30. The anti-glare mounting plate 30 is provided with a light outlet 320 corresponding to the position of the reflector 70. An anti-glare cover 310 is provided inside the light outlet 320. The anti-glare cover 310 is in communication with the reflector 70.

[0018] In this utility model, the lamp plate 50 is fixedly installed on the movable plate 40 with screws, and the first connecting plate 60 can be fixed on the lamp plate 50 by means of buckle or screw connection.

[0019] Specifically, a buckle is provided on the anti-glare mounting plate 30, and a slot is provided on the first connecting plate 60, with the buckle and the slot engaging with each other.

[0020] Specifically, the reflector cup 70 is provided with a limiting ring 710 that fits against the lower end face of the anti-glare cover 310, and the upper end of the reflector cup 70 extends into the lower end opening of the anti-glare cover 310.

[0021] In this utility model, the peripheral walls of the movable plate 40, the first connecting plate 60, and the anti-glare cover mounting plate 30 are in contact with the inner wall of the lamp housing 10.
