Detailed Description

In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to specific embodiments of the present utility model and corresponding drawings. It will be apparent that the described embodiments are only part embodiments of the utility model and not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the embodiment of the present utility model, referring to fig. 1, 2 and 3, a lighting device 100 includes a fan 10, an air guiding structure 20, an air duct 30 and a lighting module 40. The lighting module 40 includes a housing assembly 41 and a light source assembly 42, wherein the housing assembly 41 includes a light-emitting surface 411 and a first cover top 412 which are disposed opposite to each other, and a first wall 413 connecting the light-emitting surface 411 and the first cover top 412, and the light source assembly 42 is disposed in the housing assembly 41, connected to the first cover top 412, and emits light in a direction of the light-emitting surface 411. The fan 10 is disposed on a side of the housing assembly 41 facing away from the light-emitting surface 411, the fan 10 has an air inlet 11 and an air outlet 12 which are mutually communicated, the air guiding structure 20 connects the air outlet 12 and the first cover top 412, and an air duct 30 which is communicated with the air outlet 12 is formed on a space outside the first wall 413 and on the periphery of the light-emitting surface 411.

Therefore, in the lighting device 100 of the embodiment of the utility model, the lighting module 40 and the fan 10 are integrally arranged, the fan 10 and the air guiding structure 20 are connected to the backlight surface of the lighting module 40, and the air duct 30 is arranged in the peripheral space of the light emitting surface 411, so that the lighting device 100 can realize the lighting function and also has the ventilation function with a smaller volume, and the problem that the space is more crowded due to the fact that a plurality of ventilation devices and the lighting device 100 are respectively arranged in a narrow space is solved. Thus, the lighting device 100 of the embodiment of the present utility model integrates both functions of lighting and a summer heat with a smaller volume.

In the embodiment of the present utility model, referring to fig. 5 and 6, the air guiding structure 20 may include an air guiding cover 21, air guiding blades 22 and a supporting portion 23. The air guide cover 21 may include an air outlet 211 and a second cover top 212 disposed opposite to each other, and a second wall surface 213 connecting the air outlet 211 and the second cover top 212. The supporting portion 23 may be disposed inside the wind scooper 21, each wind scooper may correspond to a circumferential edge of the extending value supporting portion 23 from a circumferential direction of the second cap top 212, and the first gaps 31 are maintained between the wind scoopers 22. The air guide cover 21 may cover the housing assembly 41 from the first cover top 412 toward the light exit surface 411, and the support portion 23 may be connected to the first cover top 412. The first wall 413 and the second wall 213 may have a second gap 32 therebetween, and the first gap 31 and the second gap 32 are communicated with each other to form an air duct 30 communicating with the air outlet 211 and the air flow outlet 12.

Since the first gaps 31 are formed by gaps between the respective wind guide blades 22, the first gaps 31 may extend substantially in the longitudinal direction, and the plurality of first gaps 31 are arranged in the circumferential direction; and the second gap 32 is formed by the first wall 413 and the second wall 213, so that the second gap 32 is annular in the warp direction; as can be seen from fig. 2 and 4, the air duct 30 of the lighting device 100 is annular on the surface of the light exit surface 411.

After the lighting device 100 of the embodiment of the utility model is installed in a narrow space, when the fan 10 is operated, air flow outside the narrow space flows into the narrow space through the air flow inlet 11, and flows into the narrow space through the air flow outlet 12, the first sub-gap, the second sub-gap and the air outlet 211 in sequence under the drainage effect of the fan 10, so that the air circulation in the narrow space is promoted. When the lighting module 40 is powered on, light can be emitted through the light emitting surface 411. Therefore, the lighting device 100 of the embodiment of the present utility model can realize double disclosure of lighting and ventilation without increasing the surface space occupying a narrow space.

In the embodiment of the present utility model, the air duct 30 of the lighting device 100 may be streamlined, that is, the first gap 31, the second gap 32, and the air outlet 211 are communicated with the air flow outlet 12 and are streamlined, so that the air flow outside the narrow space passes through the air flow inlet 11, and then sequentially and smoothly passes through the air flow outlet 12, the first sub-gap, the second sub-gap, and the air outlet 211 under the action of the fan 10, and then enters the narrow space.

In one embodiment, the air guiding blades 22 may be uniformly arranged along the circumferential direction of the second cover top 212 or the supporting portion 23, so that the air from the air flow outlet 12 of the fan 10 may uniformly enter the first gap 31, the second gap 32 and the air outlet 211, which improves the uniformity of the air flow, and also makes the circumferential air pressure of the lighting module 40 uniform, and improves the stability of the lighting module 40 in the lighting device 100. Of course, in some embodiments, instead of the air guiding blades 22 being uniformly arranged along the circumferential direction, only two air guiding blades 22 for connecting the supporting portion 23 and the second cover top portion 212 may be provided.

The air guiding blade 22 extends from the circumferential direction of the second cover top 212 to the circumferential edge of the supporting portion 23, that is, the circumferential edge of the supporting portion 23 does not protrude radially outwards relative to the air guiding blade 22, so that the air flow in the air duct 30 is not blocked, the resistance of the air flow in the air duct 30 is reduced, the air duct 30 is smoother, and the working efficiency of the fan 10 is improved. Of course, in some embodiments, if the working efficiency of the fan 10 is not limited, the air guiding blade 22 may extend from the circumferential direction of the second cover top 212 to the central region of the supporting portion 23 correspondingly.

As a modification, the air guiding structure 20 of the lighting device 100 may not be provided with the air guiding cover 21, that is, the second wall 213 and the first wall 413 do not need to define the second gap 32 together, and the second gap 32 is used as a part of the air duct 30 in the lighting device 100. In other words, all the spaces outside the first wall 413 and outside the light-emitting surface 411 may be considered as a part of the air duct 30, that is, the air duct 30 of the lighting device 100 is open on the surface of the light-emitting surface 411, instead of the air duct 30 of the lighting device 100 being annular on the surface of the light-emitting surface 411 as illustrated in fig. 4.

In the embodiment of the present utility model, a distance may be kept between the supporting portion 23 and the second cover top portion 212, so that the air guiding blade 22 can extend from the second cover top portion 212 to the supporting portion 23. The radial dimension of the supporting portion 23 is smaller than the radial dimension of the second cover top portion 212, and the vertical distance between the position of each wind guiding blade 22, which is closer to the supporting portion 23, and the central axis of the wind guiding structure 20 is smaller, in other words, the radial dimension of each wind guiding blade 22, which is connected to the second cover top portion 212, is the largest, and the radial dimension of each wind guiding blade 22, which is connected to the supporting portion 23, is the smallest, so that the first gap 31 between the air outlet 12 and the second gap 32 can be close to streamline, and the air flow resistance in the air duct 30 is smaller.

In order to make the air flow smoothly enter the second gap 32 from the first gap 31, the supporting portion 23 may further include a convex arc surface 231, the convex arc surface 231 protrudes toward the direction of the fan 10, and the air flow changes direction to flow to the outer circumference after contacting the convex arc surface 231 in the first gap 31, so as to smoothly enter the second gap 32. Accordingly, the convex cambered surface 231 on the support portion 23 serves to guide the air flow entering from the fan 10 into the second gap 32.

A plurality of through holes 232 may be formed through the support 23 in an axial direction, and the through holes 232 may be used for wires connected to external power to pass through to supply power to the light source assembly 42. Of course, the through hole 232 may also be used as a connection hole to connect the support 23, the first cover top 412, and the light source module 42.

In the embodiment of the present utility model, the light emitting surface 411 and the air outlet 211 may be located on the same radial surface, so that the surface exposed to the user in use of the lighting device 100 is flush and beautiful. Of course, as a variant, the light-emitting surface 411 and the air-outlet 211 may be located on different radial surfaces, for example, the vertical distance from the air-outlet 211 to the top 412 of the first cover is shorter or longer than the light-emitting surface 411.

In an embodiment of the present utility model, the lighting device 100 may further include a mounting bracket 50, where the mounting bracket 50 may be disposed outside the wind scooper 21 and connected to the second wall 213. Wherein the mounting bracket 50 is located between the second cover top 212 and the air outlet 211 for connecting the lighting device 100 to a mounting base.

In the embodiment of the present utility model, the direction of the air flow inlet 11 of the fan 10 may be opposite to the direction of the air flow outlet 12. Wherein the fan 10 may be an axial flow fan.

In an embodiment of the present utility model, the light source assembly 42 may include a light source board and a light emitting unit, where the light emitting unit is disposed on the light source board. The light source plate, the first cover top 412 and the support 23 are sequentially connected in an abutting manner, and for example, the three can be screwed by using a fastener such as a screw. The light source module 42 may further include a lens that houses the light emitting unit for distributing light thereto.

In order to make the air flow of the air duct 30 in the lighting device 100 smoothly enter the narrow space, the radial dimension of the second gap 32 between the first wall 413 and the second wall 213 is smaller as the air flow is closer to the air outlet 211, and when the air flow is in the second gap 32, the flow velocity of the air flow closer to the air outlet 211 is faster, so that the air flow can flow forward after flowing out from the air outlet 211, and further long-distance air supply is realized.

In the embodiment of the present utility model, the air guiding structure 20 may be a rotating body structure, the housing assembly 41 may be a rotating body structure, and the central axis of the air guiding structure 20 and the central axis of the housing assembly 41 are coaxially arranged, so that the second gap 32 in the lighting device 100 is also a rotating body structure, the air duct 30 is also a rotating body structure, the central axis of the air duct 30 of the lighting device 100 is also coaxial with the central axis of the air guiding structure 20 and the central axis of the housing assembly 41, and the pressure of the air duct 30 in the circumferential direction of the lighting device 100 is uniform.

In an embodiment of the present utility model, the wind scooper 21 may further include a flange 214, and the flange 214 extends radially outward from the second wall 213 at a position away from the second housing top 212. In one embodiment, the flange 214 may be flush with the light exit along the warp face. The flange 214 is intended to be disposed under a mounting plate 1 (e.g., a ceiling) when the lighting device 100 is mounted to a mounting base. Wherein the flange 214 may extend radially outward a length L of greater than or equal to 10mm. Referring to fig. 7, the flange 214 is configured to cooperate with the mounting bracket 50, where the flange 214 is located below the mounting plate 1 and the mounting bracket 50 is located above the mounting plate 1, and the flange 214 and the mounting bracket cooperate to clamp the mounting plate 1 (e.g., a ceiling) on the mounting base, so as to mount the lighting device 100 on the ceiling. Due to the provision of the flange 214, as shown in fig. 7 and 8, the surface of the entire ceiling after installation is tidy, so that the lighting device 100 occupies fewer positions in a small space.

In an embodiment of the present utility model, the housing assembly 41 may include a reflective cover and a lamp cover. The reflective cover includes a first cover top 412 and a light outlet, which are disposed opposite to each other, and a first wall 413 connecting the first cover top 412 and the light outlet, and the light outlet is covered by the lamp cover to form a light outlet 411. Wherein the inner surface of the reflective cover may be provided with a reflective coating and the lamp housing may be made of a light transmissive material.
