Description

Technical Field

[0001] The utility model belongs to the technical field of the lighting structure of a photovoltaic inverter, and more specifically, relates to a light-shielding lamp cover structure of an inverter. Background Art

[0002] With the rapid development of new energy technologies, as a core device for energy conversion, inverters are widely used in many electrical fields. During use, their operating status indication function is crucial for user operation and maintenance. The existing lighting indication structures of inverters generally have the following technical defects: The traditional lamp cover structure is simple and lacks an effective light-shielding design, resulting in light scattering and interference between multiple indicator lights, forming a halo phenomenon. Especially in multi-color display scenarios (such as fault, operation, standby states), color mixing is severe, and it is difficult for users to clearly identify the functional status. The light guiding of a conventional lamp cover relies on a single diffusion structure, with poor light uniformity, insufficient brightness in the functional display area, and blurred indication effects in low-light environments, affecting user experience and safety.

[0003] In response to the above problems, the prior art has tried to improve by adding light-shielding sheets, optimizing the light transmittance of the lamp cover, or increasing the density of lamp beads, etc., but often leads to complex structures, increased costs, and it is difficult to balance the concentrated light efficiency requirements. Therefore, the utility model provides a light-shielding lamp cover structure of an inverter. Summary of the Utility Model

[0004] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a light-shielding lamp cover structure of an inverter, which can effectively provide users with relevant clear lighting auxiliary expression functions through a simple structure.

[0005] The purpose of the utility model can be achieved by the following technical solutions:

An installation groove matching the acrylic face sticker is provided on the front shell body. The acrylic face sticker is attached to the installation groove. The lamp cover is fixedly connected to the lower end of the installation groove. The lamp board is fixedly connected to the lower end of the lamp cover. A plurality of mutually independent first light-shielding areas are provided on the lamp cover. A plurality of second light-shielding areas are provided on the lamp cover. The second light-shielding areas are provided at one end of the first light-shielding areas. Through holes corresponding to the positions of the first light-shielding areas and the second light-shielding areas are provided on the front shell body. A plurality of patch lights corresponding to the positions of the first light-shielding areas and the second light-shielding areas are provided on the lamp board. Reflective layers are provided on both the first light-shielding areas and the second light-shielding areas. One or more first inclined plates are inclined on the horizontal plane of the lamp cover in the first light-shielding areas. One or more second inclined plates are inclined on the horizontal plane of the lamp cover in the second light-shielding areas. The inclination angle of the first inclined plate is greater than the inclination angle of the second inclined plate.

[0013] As described above, a light shielding lamp cover structure of an inverter provided by the present utility model has the following beneficial effects:

[0014] With the light shielding lamp cover structure of an inverter of the present utility model, compared with the prior art, due to adopting such a structure, through the independent design of the first light shielding area and the second light shielding area, combined with the first inclined plate and the second inclined plate with different inclination angles, and cooperating with the reflective layer, directional reflection and light concentration of light are realized. The first light shielding area and the second light shielding area will guide the light to focus on the function display area of the acrylic surface sticker, and the second light shielding area will enhance the display brightness. The two areas cooperate to make the function light display clear and independent, avoid halo interference, and effectively reduce the misjudgment rate.

The specific structure can be described with reference to the drawings of the patent application.

[0029] The present utility model provides a light isolation lamp cover structure for an inverter. Please refer to Figures 1 to 8 As shown, a light isolation lamp cover structure for an inverter includes a front shell body 100, a lamp board 300, a lamp cover 200 and an acrylic face sticker 400. An installation groove 110 matching the acrylic face sticker 400 is provided on the front shell body 100. The acrylic face sticker 400 is attached to the installation groove 110. The lamp cover 200 is fixedly connected to the lower end of the installation groove 110. The lamp board 300 is fixedly connected to the lower end of the lamp cover 200. A plurality of independent first light isolation areas 210 are provided on the lamp cover 200. A plurality of second light isolation areas 220 are provided on the lamp cover 200. The second light isolation areas 220 are arranged at one end of the first light isolation areas 210. Through holes 120 corresponding to the positions of the first light isolation areas 210 and the second light isolation areas 220 are provided on the front shell body 100. A plurality of patch lamps 310 corresponding to the positions of the first light isolation areas 210 and the second light isolation areas 220 are provided on the lamp board 300. Reflective layers are provided on both the first light isolation areas 210 and the second light isolation areas 220. Specifically, the lamp cover 200 separates the patch lamps 310 through a plurality of first light isolation areas 210 and second light isolation areas 220, and displays corresponding functions through the lights. Moreover, the light displays in different functional areas are independent of each other. The first light isolation areas 210 and the second light isolation areas 220 isolate the lights from interfering with each other, avoiding the blurring of the light display in the functional area caused by the disorder of the lights and the misjudgment of the functions.

[0030] It should be noted that one or more micro bolts 130 are provided below the installation groove 110 of the front shell body 100. The lamp shade 200 is provided with connection holes 240 corresponding to the micro bolts 130, and a locknut 500 is arranged on the micro bolts 130. Specifically, the number of the micro bolts 130 is three. The connection holes 240 penetrate into the corresponding micro bolts 130, and the lamp shade 200 is fixed on the front shell by the locknut 500.

[0031] It should be noted that a plurality of threaded posts 230 are provided on the lamp shade 200, and round holes 320 corresponding to the threaded posts 230 are provided on the lamp board 300. A plurality of limiting blocks for limiting the lamp board 300 are arranged at equal angles on the outer circumference of the threaded posts 230. Specifically, the number of the limiting blocks is four. The limiting blocks are arranged on the threaded posts 230 at equal angles. The threaded posts 230 are internally provided with threaded holes. The round holes 320 on the lamp board 300 penetrate into the threaded posts 230 and abut against the limiting blocks, indicating that the lamp board 300 is closely attached to the lamp shade 200. The first light shielding area 210 covers the corresponding surface mount lamp 310, and the second light shielding area 220 covers the corresponding surface mount lamp 310. A fastener cooperates with the threaded posts 230 to fix the lamp board 300 on the lamp shade 200, and the lamp board 300 is compounded on the lowermost layer of the front shell body 100, which is convenient for heat dissipation of the lamp board 300 and convenient for direct replacement when the lamp board 300 is damaged, without the need to remove the lamp shade 200 and the acrylic face sticker 400.

[0032] It should be noted that the first light shielding area 210 is in a long strip shape, and the second light shielding area 220 is in a rectangular shape. Among them, the first light shielding area 210 corresponds to guiding light for functions, and the second light shielding area 220 corresponds to the function display area of the acrylic face sticker 400. The first light shielding area 210 and the second light shielding area 220 complement each other. The guiding light is guided to the corresponding function display area. When the surface mount lamp 310 in the first light shielding area 210 lights up, it means that the surface mount lamp 310 in the corresponding function display area will also light up. If one of the surface mount lamps 310 in the first light shielding area 210 and the second light shielding area 220 does not light up, it means that the lamp board 300 may be damaged and the lamp board 300 needs to be replaced or repaired.

[0033] It should be noted that one or more first inclined plates 211 are inclinedly arranged on the horizontal plane of the upper lamp cover 200 in the first light shielding area 210, and one or more second inclined plates 221 are inclinedly arranged on the horizontal plane of the upper lamp cover 200 in the second light shielding area 220. The inclination angle of the first inclined plate 211 is greater than that of the second inclined plate 221. Specifically, the first inclined plate 211 and the second inclined plate 221 are located on the lamp board 300, and the reflective layer is on the inclined surfaces facing the housing body 100 on the first inclined plate 211 and the second inclined plate 221. The reflective layer is prepared from one or more materials such as molybdenum, aluminum, and silicon carbide. The best choice is molybdenum, which has good thermal conductivity and can guide the heat generated by the light emission in the surface mount lamp 310 to assist in heat dissipation. Moreover, the reflective layer reflects the light emitted by the surface mount lamp 310, improving the lighting condition of the surface mount lamp 310. Both the first inclined plate 211 and the second stopper are inclinedly arranged. The first light shielding area 210 is composed of two opposite first inclined plates 211 and two stoppers. The two first inclined plates 211 expand from the lamp board 300 towards the housing. The inclination angle of the first inclined plate 211 is 80 degrees. The first inclined plate 211 on the first light shielding area 210 reflects the light scattered towards the first inclined plate 211, which can focus the scattered light to increase the lighting effect. The second light shielding area 220 is composed of four second inclined plates 221. The second light shielding area 220 corresponds to the function display area of the acrylic surface sticker 400. The inclination angle of the second inclined plate 221 is 60 degrees. The inclination angle of the first inclined plate 211 is larger than that of the second inclined plate 221, that is, the inclined surface of the second inclined plate 221 is larger than that of the first inclined plate 211. The height at which the light reflected by the second inclined plate 221 is concentrated is lower than the height at which the light reflected by the first inclined plate 211 is concentrated, better concentrating the reflected light on the acrylic surface sticker 400 and improving the display brightness of the function display area, having a good light display effect.

[0034] It should be noted that one or more surface mount lamps 310 are arranged in the first light shielding area 210, and one surface mount lamp 310 is arranged in the second light shielding area 220. The surface mount lamp 310 is a three-color lamp. The three-color lamp can synthesize various colors of light using the principle of the three primary colors, providing different light color displays for different functions and having rich light display colors.

[0035] It should be noted that heat dissipation strips are arranged on the other side of the lamp board 300 at the position corresponding to the surface mount lamp 310. The heat dissipation strips are made of brass material, and the lamp board 300 is compounded on the outermost side of the housing body 100, that is, the heat dissipation strips are located on the outermost side. The surface mount lamp 310 is a long-term display device and will continuously generate heat during use. The outermost heat dissipation strips can provide better heat dissipation effects.

[0036] Light reflection process of the light shield: The surface-mounted lamp 310 on the lamp board 300 is powered on and lit. The light of the surface-mounted lamp 310 is diffused. Since the first light-shielding area 210 and the second light-shielding area 220 are closely attached to the surface-mounted lamp 310, part of the light diffuses out along the middle of the first light-shielding area 210 and the second light-shielding area 220. Most of the light is reflected under the reflective layer on the first inclined plate 211 and the second inclined plate 221. Because the first inclined plate 211 and the second inclined plate 221 are both inclined, and the reflective layer is located on the inclined surfaces of the first inclined plate 211 and the second inclined plate 221 facing the housing body 100, the light reflected by the reflective layer is concentrated on the function display area of the acrylic face sticker 400, enhancing the lighting effect, making the function display area of the acrylic face sticker 400 more obvious, and providing clear relevant light indications for users.

[0037] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
