[0003] Lighting device as the basic configuration of range hood, generally set below the fume hood, frame side plate or fan cover. At present, long strip LED lamp is commonly used as lighting device, and generally this lighting device does not install limit or design a limit structure in the middle or a position of device, such as the lighting lamp disclosed in the Chinese patent with application number 202420403116.9. The prior art has the following problems: 1, this design usually can not play the effect of limiting, when product is assembled, because the limiting rib on the lamp shell is relatively low, and the rigidity of the metal mounting hole on the whole machine is insufficient, so the LED lamp is still often deviated to one side of the lamp hole. 2, because range hood exists in the process of use and storage, cold and hot alternation, and the thermal expansion coefficient between the plastic shell of LED lamp and the LED lamp metal mounting hole on the whole machine is relatively large, so the metal mounting hole is usually designed to be much larger than the plastic shell of LED lamp.

[0004] Therefore, in the prior art, the installation of LED lamp can appear that one side is close to the metal mounting hole, and the other side has a large gap with the metal mounting hole, which affects the consistency of the whole machine product, and oil is easy to accumulate in the gap, affecting the lighting effect and cleaning difficulty. INVENTION CONTENTS

[0005] The first technical problem to be solved by the utility model is to provide a lighting device mounting structure to improve installation precision in view of the deficiencies of the prior art.

[0006] The second technical problem to be solved by the utility model is to provide a range hood applied with the above lighting device mounting structure.

[0007] The technical scheme adopted by the utility model to solve the above first technical problem is: a lighting device mounting structure, comprising a lighting device and a mounting plate for installing the lighting device, the lighting device comprises:

[0008] A lamp shell comprising a shell body in the form of a whole strip, one side of the shell body is open;

[0009] A lamp panel is installed in a lamp shell; and

[0010] A lamp shade is arranged at the opening of the shell;

[0012] The two ends of the shell in the length direction are respectively provided with guide ribs, the guide ribs extend from the position close to the lamp shade to the position away from the lamp shade in the height direction of the shell, and the guide ribs can cooperate with the corresponding edges of the mounting hole.

[0013] The guide ribs are added at the two ends of the lighting device in the length direction, so that the edges of the mounting hole of the mounting plate cooperate, play a guiding role in the installation process, and make the lighting device centered in the mounting hole.

[0014] Preferably, to have a better guiding effect, the end of the guide rib away from the lamp shade is formed with a guide surface, the guide rib has a higher height at the position farther away from the lamp shade and a lower height at the position closer to the lamp shade, and the guide surface gradually moves away from the shell as the height of the guide rib decreases.

[0019] Further, the limiting rib extends along the height direction of the shell from a position close to the lampshade to a position away from the lampshade, the position farther away from the lampshade is higher in height and the position closer to the lampshade is lower in height, the end of the guide rib close to the lampshade is higher than the surface of the folded edge away from the flange, and the end of the limiting rib away from the lampshade is higher than the end of the guide rib close to the lampshade. Thus, when the lighting device is installed on the mounting plate, the gap between the limiting rib and the notch in the middle of the mounting plate is matched.

[0020] Further, along the length direction of the lamp shell, the side of the guide rib away from the shell is configured as a limiting surface, and the limiting surface and the folded edge of the mounting plate are in transition fit. Thus, in the extreme case, the gap or interference between the limiting surface of the guide rib and the folded edge is as small as possible, and the installation position of the lighting device is ensured to be as centered as possible.

[0024] Further, one end of the shell in the length direction of the lamp shell is provided with a wire outlet for leading out the lead-out wire of the lamp panel.

[0025] Further, the outer periphery of the open side of the shell of the lamp shell is provided with a flange, and the guide rib is located between the flange and the wire outlet, so as to facilitate the lead-out wire to pass out and be sealed by glue during production.

[0042] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the specific embodiments below. Those skilled in the art should understand that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, elements and circuits well known to those skilled in the art are not described in detail, in order to highlight the main idea of the present disclosure.

[0043] Referring to Figures 1-6 A lighting device mounting structure includes a lighting device 100 and a mounting plate 200, the mounting plate 200 as the mounting base of the lighting device 100, can be part of the smoke hood 300 of the extractor hood, such as Figure 7As shown, the lighting device 100 is typically installed in front of or above the smoke inlet on the smoke hood 300.

[0044] The lighting device 100 includes a lamp panel 1 and a lamp housing 2. The lamp housing 2 is generally elongated, and the lamp panel 1 is disposed inside the lamp housing 2. The lamp housing 2 includes a generally elongated shell 23 with an open side. A lampshade 3 is disposed at the open side of the shell 23 to allow the light emitted by the lamp panel 1 to shine outward. In this embodiment, the lampshade 3 is flat. Typically, in the case of a range hood, the lampshade 3 is located at the bottom of the lamp housing 2. A flange 21 is formed on the outer periphery of the open side of the shell 23 of the lamp housing 2. The flange 21 is annular and can be used for mounting with the lampshade 3.

[0045] Guide ribs 24 are provided at both ends of the shell 23 along its length. The guide ribs 24 are integrally formed with the shell 23 and are located on the outer side of the shell 23. The guide ribs 24 extend along the height direction of the shell 23. Figure 5 Arrow X) as shown extends from the position near the lampshade 3 to the position away from the lampshade 3, with the height increasing as it moves away from the lampshade 3 and decreasing as it moves closer to the lampshade 3. Preferably, the end (upper end) of the guide rib 24 away from the lampshade 3 has a guide surface 241, which gradually moves away from the housing 23 as the height of the guide rib 24 decreases, thereby facilitating centered installation even if the lighting device 100 is not aligned.

[0046] The mounting plate 200 includes a base plate 201 with mounting holes 202. When the lamp housing 2 of the lighting device 100 passes through the mounting hole 202 on the side away from the lampshade 3, the guide surface 241 of the guide rib 24 first contacts the edge of the mounting hole 202, guiding the lighting device 100 to be installed in the center. The mounting plate 200 also includes a flange 203, which is formed by folding the edge of the mounting hole 202 on the base plate 201 relative to the base plate 201. In the installed state, the flange 203 wraps around the outer periphery of the lamp housing 2.

[0047] The two sides of the shell 23 of the lamp shell 2 in the width direction are respectively provided with a limiting rib 25. The limiting rib 25 can be arranged at the middle position of the shell 23 along the length direction. Similarly to the guide rib 24, the limiting rib 25 also extends along the height direction of the shell 23 from the position close to the lamp shade 3 to the position away from the lamp shade 3. The farther away from the lamp shade 3, the higher the height is. The closer to the lamp shade 3, the lower the height is. The position corresponding to the limiting rib 25 on the turn-up edge 203 is formed with a notch 204. The limiting rib 25 can be clamped into the notch 204, so as to limit the position of the lamp shell 2 relative to the mounting plate 200. In the embodiment, the limiting rib 25 on each side in the width direction has two, which are arranged at intervals along the length direction of the lamp shell 2. The notch 204 also has two, which are matched with each limiting rib 25 respectively. Alternatively, only one notch 204 can be arranged. The length of the notch 204 is slightly greater than the sum of the interval of the limiting rib 25 and the length of the limiting rib 25, so that the two limiting ribs 25 can be partially matched in the notch 204.

[0048] The limiting rib 25 cannot guarantee the central installation of the lighting device 100 alone. The guide rib 24 makes up for the problem that the limiting rib 25 cannot guide. Even if the lighting device 100 is not aligned during installation, the assembly position can be centered under the action of the guide rib 24, so as to guarantee the installation precision and improve the delicacy of product installation.

[0049] The turn-up edge 203 of the mounting plate 200 is formed with a turn-up edge 205 at the position corresponding to the two ends of the length direction of the lamp shell 2. In the mounted state, the turn-up edge 205 abuts against the surface of the flange 21 of the lamp shell 2 away from the lamp shade 3, so as to limit the limit position of the lighting device 100 installed into the mounting hole 202. The end of the guide rib 24 close to the lamp shade 3 has a gap 242 along the height direction of the lamp shell 2 between the flange 21 of the lamp shell 2. The gap 242 is sufficient for the turn-up edge 205 to be inserted, so that the interference between the turn-up edge 205 (usually the mounting plate 200 is a metal piece) and the guide rib 24 when heated and expanded can be avoided, and the problem of different linear expansion coefficients of the plastic piece (the lamp shell 2) and the metal piece (the mounting plate 200) when heated is considered. The existence of the gap 242 will not affect the guiding effect of the guide rib 24. During installation, the part of the guide rib 24 that is first installed (the upper half in the figure) plays a guiding role. Figure 5

[0050] One end of the shell 23 of the lamp shell 2 in the length direction is provided with a wire outlet 22 of the lead wire (not shown) of the lamp panel 1, so that the overall height of the lighting device 100 can be avoided due to the lead wire. Therefore, the guide rib 24 should be located between the flange 21 of the lamp shell 2 and the wire outlet 22, so as to facilitate the production of the lead wire to pass out and the glue sealing.

[0051] ​Along the length direction of the lamp shell 2, the side of the guide rib 24 away from the shell 23 is configured as a limiting surface 243, which preferably adopts a transition fit with the folded edge 205 of the mounting plate 200. In this way, in the extreme case, the gap or interference between the limiting surface 243 of the guide rib 24 and the folded edge 205 is as small as possible, and the installation position of the lighting device 100 is as centered as possible, thereby improving the product delicacy.

[0052] Along the height direction of the lamp shell 2, the end of the guide rib 23 close to the lamp shade 3 (the lower end shown in the figure) should be higher than the surface of the folded edge 205 away from the flange 21 (the upper surface shown in the figure), and the end of the limiting rib 25 away from the lamp shade 3 (the upper end shown in the figure) should be higher than the end of the guide rib 23 close to the lamp shade 3. In this way, when the lighting device 100 is installed to the mounting plate 200, the gap 204 in the middle of the mounting plate 200 has been matched with the limiting rib 25. The distance between the lamp shell 2 and the folded edge 205 of the mounting plate 200 is related to the overall length of the lighting device 100 and the working environment temperature, and the gap is preferably slightly larger than the difference in thermal expansion between the lamp shell 2 and the mounting plate 200.
