CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202211447602.2, entitled “LED LAMP” and filed on Nov. 8, 2022, the content of which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

BACKGROUND

LED lamps have the advantages of energy saving, high brightness, convenient control and so on, and are widely used in various lighting places. LED plant growth lamps are one type of these. The LED plant growth lamps can be used to provide light required by photosynthesis of indoor plants.

The LED lamps usually include LED light board and power supply, both of which will produce a lot of heat, and will have high heat dissipation requirements, otherwise performance and service life of both will be affected. The heat dissipation effects of traditional LED plant growth lamps are not good. In addition, in order to save planting space and save the cost of the space, three-dimensional structures were adopted in many indoor planting places, to expand the plant area and improve the yield achieved under the same ground area. The traditional LED plant growth lamps generally use flat lighting, that is, have only one lighting surface, which will lead to that some plants located in the three-dimensional cannot get sufficient lighting, which will affect the growth of these plants. In addition, the existing LED plant growth lamps are large and occupy too much space, and thus the planting area of plants is reduced. Therefore, it is necessary to improve the existing LED lamps.

DETAILED DESCRIPTION

In order to make the objects, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and do not limit the scope of protection of the present disclosure.

Referring to the embodiment of the present disclosure shown in FIG. 1 to FIG. 13, an LED lamp includes a heat sink 1, a plurality of LED light boards 2, an LED driving power 3 and a diffuser 4. The heat sink 1 is a long hollow tubular structure. The heat sink 1 includes a top plate 5 and a plurality of mounting plates 6, and an angle is defined between two adjacent mounting plates 6. The LED light boards 2 are arranged on outer surface of each mounting plate 6. The outer surface of the top plate 5 is exposed to air. The LED driving power 3 is received in the heat sink 1. The diffuser 4 covers all the LED light boards 2, and is connected to the heat sink 1. Two end covers 7 are separately arranged on two ends of the heat sink 1. Since the heat sink 1 has a plurality of mounting plates 6, and an angle is defined between the adjacent two mounting plates 6, a plurality of LED light boards 2 with different lighting angle can be installed, and the luminous angle and the irradiation area of the LED lamp can be improved. In addition, the top plate of the heat sink 1 directly contacts to the outside air, which can improve the heat dissipation effect of heat sink 1. The diffuser 4 can improve the water resistance of the LED lamp, thus the LED lamp is especially suitable for humid place planting such as indoor plant planting. Further, the end covers 7 can also improve the water resistance of the LED lamp.

In some embodiments, as shown in FIG. 5 to FIG. 13, the heat sink 1 includes the top plate 5 and three successively connected mounting plates 6. An angle is defined between two adjacent mounting plates 6, and an LED light board 2 is respectively installed on the outer surface of each of the mounting plates 6. Since the heat sink 1 is provided with three mounting plates 6, and the angle is defined between the two adjacent mounting plates 6, then the LED light boards 2 totally adopting three luminous angles can be installed, which can improve the luminous angle and irradiation area of the LED lamp. It is understood that the numbers of mounting plates 6 are not limited to this embodiment, and can also be two or more than three, such as four, five and so on. It is understood that a plurality of the mounting plates 6 can be connected directly, and can also be set at intervals. All of the outer surface of the heat sink 1 can be installed with LED light boards except the top plate 5, or, some of the outer surface of the heat sink 1 can be installed with LED light boards except the top plate 5. It can be understood that the angle between the two adjacent mounting plates 6 can be an acute angle, an obtuse angle or a right angle. The following are three mounting plates 6 connected in turn as an example.

In some embodiments, as shown in FIG. 5 to FIG. 10, the three mounting plates 6 respectively are a first side plate 8, a bottom plate 9 and a second side plate 10 connected sequentially. An angle of 90 degrees is defined between the two adjacent mounting plates 6, that is, the heat sink 1 has a hollow cuboid tubular structure. The bottom plate 9 is opposite to the top plate 5, the first side plate 8 is opposite to the second side plate 10, and the top plate 5 is adjacent to the first side plate 8 and the second side plate 10. Three LED light boards 2 are separately arranged on outer surface of the first side plate 8, the bottom plate 9 and the second side plate 10, and thus, the LED lamp can realize the irradiation on left, right and below, and further can obtain a large luminous angle and a large irradiation area.

In some embodiments, the LED driving power 3 can be fixed to the heat sink 1 by fasteners.

In some embodiments, as shown in FIG. 8 to FIG. 10, the inner surface of the top plate 5 and the inner surface of the bottom plate 9 are respectively provided with a slot 11. Each slot 11 is inserted with a power fixing board 12, the LED driving power 3 is installed on the power fixing boards 12, and thus the LED driving power 3 is fixed on the heat sink 1 through the power fixing boards 12 and the slots 11. This structure can realize a compact structure of the LED lamp, and the heat generated by the LED driving power 3 can also be transferred to the heat sink 1 through the power fixed board 12, to ensure the radiation effect of the LED driving power 3.

Specifically, in some embodiments, as shown in FIG. 8 to FIG. 10, the slot 11 located on the top plate 5 is defined between two first ribs 51 convex on the inner surface of the top plate 5. The extension direction of the two first ribs 51 is consistent with the long direction of the heat sink 1. In this embodiment, the two first ribs 51 are integrated with the top plate 5. In other embodiments, the two first ribs 51 may also be installed on the top plate 5. The slot 11 located on the bottom plate 9 is defined between two second ribs 91 convex on the inner surface of the bottom plate 9. The extension direction of the two second ribs 91 is consistent with the long direction of the heat sink 1. In this embodiment, the two second ribs 91 are integrated with the bottom plate 9. In other embodiments, the two second ribs 91 may also be installed on the bottom plate 9. Of course, in other embodiments, the slots 11 may also be depressions formed directly into the interiors of the top plate 5 and the bottom plate 9. In this embodiment, the slots 11 are positioned adjacent to the first side plate 8, and in other embodiments, the slots 11 can also be positioned adjacent to the second side plate 10, as long as sufficient space is left to install the device inside the heat sink 1. The following embodiments are illustrated by the slots 11 adjacent to the first side plate 8 as an example.

In some embodiments, as shown in FIG. 5 to FIG. 7, the power fixing board 12 includes a body 13. The body 13 is roughly flat-like, and two opposite ends of the body 13 are respectively stuck into the slots 11 which are arranged on the top plate 5 and the bottom plate 9. A gap is defined between the body 13 and walls of the heat sink 1. Specifically, in this embodiment, the body 13 includes a first side surface 14 and a second side surface 15 opposite to the first side surface 14. The second side surface 15 is closer to the first side plate 8 than the first side surface 14. The LED driving power 3 is fixed on the first side surface 14. A first gap 32 is defined between the second side surface 15 and the first side plate 8 of the heat sink 1. By setting the first gap 32, the heat generated by the LED driving power 3 and the LED light board 2 can not affect each other, and that is conducive to flowing the air inside the heat sink 1 to take away the heat generated by the LED driving power 3 and the LED light board 2.

In some embodiments, as shown in FIG. 5 to FIG. 7, the power fixing board 12 also includes a folding edge 16. The folding edge 16 is perpendicularly extended from an end of the body 13 close to the bottom plate 9, along a direction away from the first side plate 8. Fasteners arranged on the folding edge 16 can fix the power fixing board 12 with the bottom plate 9. In this embodiment, a plurality of screw holes 17 are defined through the folding edge 16, and the folding edge 16 is fixedly connected to the bottom plate 9 of the heat sink 1 by a plurality of first screws 18 fitting with the screw holes 17. The folding edge 16 can realize the fixed connection between the power fixing board 12 and the heat sink 1. The folding edge 16 and the LED driving power 3 are located on the same side of the body 13. The folding edge 16 can strengthen the strength of the power fixing board 12, and can prevent the power fixing board 12 from deformation and releasing from the slots 11 due to overweight of the LED driving power 3.

In some embodiments, as shown in FIG. 5 to FIG. 7, a ventilation hole 19 is defined through the body 13. The ventilation hole 19 is conducive to flowing air inside the heat sink 1, and thus the heat generated by the LED driving power 3 can be better taken away. The ventilation hole 19 can be one or more, and the ventilation hole 19 can be located in the middle position or edge position of the body 13. In this embodiment, as shown in FIG. 5 to FIG. 7, the ventilation hole 19 is located at the edge of the body 13 toward the bottom plate 9 and is close to the folding edge 16.

In other embodiments, the slots 11 can also be arranged on the inner surfaces of the first side board 8 and the second side board 10, and similarly, the power fixing board 12 is inserted in the slot 11, and the LED driving power 3 is installed on the power fixing board 12. Settings of the power fixing board 12 can be referred to the above embodiments, which will not be repeated here.

In some embodiments, as shown in FIG. 1 to FIG. 13, the diffuser 4 covers all the LED light boards 2, that is, the diffuser 4 surrounds the LED light boards 2 on surfaces of the first side board 8, the bottom board 9 and the second side board 10 respectively. In this embodiment, the cross section of the heat sink 1 is square, and the cross section of the diffuser 4 is “U” shape, so as to better fit.

In some embodiments, as shown in FIG. 5 to FIG. 10, the diffuser 4 includes a cover wall 20 and a plurality of convex edges 21 protruding from the inner surface of the cover wall 20. The cover wall 20 includes a first side cover 201, a bottom cover 202 and a second side cover 203. The first side cover 201 is opposite to and spaced from the first side plate 8 of the heat sink 1. The bottom cover 202 is opposite to and spaced from the bottom plate 9. The second side cover 203 is opposite to and spaced from the second side plate 10. A second gap 22 is defined between the cover wall 20 and the first side plate 8, the bottom plate 9, and the second side plate 10. The second gap 22 can prevent the diffuser 4 from deformation and aging due to the heat of the LED light boards 2. A plurality of flanges 21 are arranged to contact with the first side plate 8, the bottom plate 9 and the second side plate 10 of the heat sink 1. The flanges 21 can prevent the diffuser 4 from deformation caused by pile pressure in the process of transportation or storage due to existence of the second gap 22.

The heat sink 1 and the diffuser 4 can be connected by a buckle. A card slot can be defined on each top portion of the first side plate 8 and the second side plate 10; a buckle can be arranged on each top end of the diffuser 4; each buckle can be connected with one card slot. In some specific embodiments, as shown in FIG. 7 and FIG. 8, a first card slot 111 is defined in the first side plate 8 of the heat sink 1 adjacent to the top plate 5, and a second card slot 112 is defined in the second side plate 10 of the heat sink 1 adjacent to the top plate 5. A first buckle 411 is arranged on an end of the first side cover 201 of the diffuser 4 away from the bottom cover 202, and a second buckle 412 is defined on an end of the second side cover 203 away from the bottom cover 202. The first buckle 411 can be accommodated in the first card slot 111, and the second buckle 412 can be accommodated in the second card slot 112. Each buckle is connected with one card slot, and thus the LED lamp is compact, and the installation between the heat sink 1 and the diffuser 4 is convenient. Of course, the card slot can also be arranged on the diffuser 4, and the buckle is arranged on the heat sink 1.

In some embodiments, as shown in FIG. 7 and FIG. 8, the first card slot 111 is a U-shaped slot and extending from the first side plate 8 along a direction away from the second side plate 10, and the second card slot 112 is a U-shaped slot and extending from the second side plate 10 along a direction away from the first side plate 8. A gate of the first card slot 111 and a gate of the second card slot 112 are faced away from each other.

The second buckle 412 is tongue-shaped and extending along a direction from the second side cover 203 to the first side cover 201. The two U-shaped slots respectively correspond to the two tongue-shaped buckles, each tongue-shaped buckle can be accommodated in one corresponding U-shaped slot, and thus the heat sink 1 and the diffuser 4 are connected.

Each card slot can include a water baffle, and the gate of the card slot can be located below the water baffle. In some specific embodiments, as shown in FIG. 7 and FIG. 8, the first card slot 111 includes a first slot plate 1111 arranged near to the top plate 5 and a second slot plate 1112 arranged away from the top plate 5. The first slot plate 1111 is substantially parallel to the second slot plate 1112 and the end of the second slot plate 1112 facing to the first side cover 201 is folded toward the first slot plate 1111. The first buckle 411 contacts with and is buckled to the second slot plate 1112. A first water baffle 231 is arranged on the end of the first slot plate 1111. The first water baffle 231 is L-shaped, and extending from the end of the first slot plate 1111 to the bottom plate 6 and then folding toward the second side plate 10, to make the gate contraction. The second card slot 112 includes a third slot plate 1121 arranged near to the top plate 5 and a fourth slot plate 1122 arranged away from the top plate 5. The third slot plate 1121 is substantially parallel to the fourth slot plate 1122 and the end of the fourth slot plate 1122 facing to the second side cover 203 is folded toward the third slot plate 1121. The second buckle 412 contacts with and is buckled to the fourth slot plate 1122. A second water baffle 232 is arranged on the end of the third slot plate 1121. The second water baffle 232 is also L-shaped and extending from the end of the third slot plate 1121 to the bottom plate 6 and then folding toward the second side plate 10, to make the gate contraction. The first water baffle 231 and the second water baffle 232 can prevent the water from flowing down from the top plate 5 of the heat sink 1 into the interior of the diffuser 4, to achieve waterproof effect.

Each buckle can include a water barrier arranged perpendicularly, and the water barrier is located at the top portion of the buckle. Each water barrier is corresponding to one water baffle on one card slot and is located on inner side of the corresponding water baffle.
