Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the detailed description is only intended to teach one skilled in the art how to practice the invention, and is not intended to exhaust all possible ways of practicing the invention, nor is it intended to limit the scope of the invention.

Unless otherwise specified, the radial direction refers to the radial direction of the body 31 (the holder 3), the circumferential direction refers to the circumferential direction of the body 31 (the holder 3), the axial direction refers to the axial direction of the body 31 (the holder 3), and the thickness direction coincides with the axial direction of the body 31.

As shown in fig. 3 and 4, the utility model provides a mounting structure of LED light source board, it includes light source board 1, bottom plate 2 and fixed knot 3, and light source board 1 and bottom plate 2 are range upon range of setting roughly parallelly, and fixed knot 3 passes light source board 1 and bottom plate 2 with the two fixed connection to make light source board 1 and bottom plate 2 along thickness direction spaced apart.

(light source board)

As shown in fig. 3 and 4, the light source plate 1 is a flat plate, and in the present embodiment, the light source plate 1 is a rectangular plate, but the light source plate 1 may be a circular plate or another shape depending on the actual situation. The light source board 1 is provided with a plurality of LED lamp beads 11, and the LED lamp beads 11 can be made to emit light by electrifying. The light source plate 1 is provided with a first through hole 12 through which the fixing buckle 3 can pass, and the first through hole 12 may be provided in plurality and located at an edge position of the light source plate 1.

(baseboard)

As shown in fig. 3 and 4, the bottom plate 2 is a flat plate shape, and the bottom plate 2 may have the same shape as the light source plate 1 and be slightly larger than the light source plate 1. The bottom plate 2 is a metal plate, the bottom plate 2 and the light source plate 1 are stacked, the bottom plate 2 is provided with a second through hole 21, the position of the second through hole 21 is aligned with the first through hole 12, and the fixing buckle 3 can penetrate through the first through hole 12 and the second through hole 21 to connect the light source plate 2 and the bottom plate 2. The second through hole may be formed by punching.

It can be understood that when the power supply of the light source board 1 is turned off, the live wire is actually only cut off, the zero line is not cut off, and weak induction voltage can exist. LED lamp pearl 11's luminous efficacy is high, because there is the voltage difference between bottom plate 2 and LED lamp pearl 11, light source board 1 is more close apart from bottom plate 2 distance, and LED lamp pearl 11 is more obvious when the luminous phenomenon of closing the power.

(fixing buckle)

As shown in fig. 3 and 4, the light source board 1 and the bottom board 2 are fixedly connected by the fixing buckle 3. The holder buckle 3 includes a body 31, a cap 32, and a locking part 33. The body 31 is cylindrical, for example, circular cylindrical. The cap 32 is provided at one axial end of the main body 31, and the radial dimension of the cap 32 is larger than that of the main body 31, so that the holder buckle 3 can be inserted through the first through hole 12 and the second through hole 21 by pressing the cap 32. The locking part 33 is provided to the main body 31 so as to protrude from a side wall surface of the main body 31, and the locking part 33 may have a circular ring shape.

The locking parts 33 are provided at regular intervals in the axial direction of the main body 31, for example, a plurality of first locking parts 331, second locking parts 332, and third locking parts 333, and the first locking parts 331, the second locking parts 332, and the third locking parts 333 are arranged in this order in the axial direction of the main body 31. The first locking part 331 is close to the cap part 32, and the second and

third locking parts

332 and 333 are gradually distant from the cap part 32.

The light source board 1 is located between the cap portion 32 and the first locking portion 331, thereby fixing the light source board 1. The bottom plate 2 is located between the second locking part 332 and the third locking part 333, thereby fixing the holder buckle 3 to the bottom plate 2. The light emitting panel 1 and the bottom plate 2 are spaced apart by a certain distance in the thickness direction by the first locking portion 331 and the second locking portion 332 being located between the light source panel 1 and the bottom plate 2. The distance between the light source board 1 and the base board 2 may be 2 mm to 10 mm, for example, the distance may be 3 mm. The distance between the first locking part 331 and the second locking part 332 may determine the distance between the light source board 1 and the bottom plate 2. It can be understood that the distance undersize between light source board 1 and bottom plate 2 can make LED lamp pearl 11 give out light comparatively obviously, and the distance between light source board 1 and the bottom plate 2 is too big can influence the holistic mounting structure of lamps and lanterns.

In addition, it is understood that in the case where the lighting device including the mounting structure of the LED light source board is mounted in a form similar to a ceiling lamp, that is, in the case where the bottom plate 2 is located above the light source board 1, the locking portion 33 may not be present between the bottom plate 2 and the light source board 1, and at this time, the space between the light source board 1 and the bottom plate 2 may be secured by means of gravity.

In addition, in order to facilitate installation and easily ensure that the interval between the base plate 2 and the light source board 1 is uniform at each holder buckle 3, a spacer may be provided between the base plate 2 and the light source board 1, and the main body 31 passes through a through hole of the spacer. The spacer may be made of a non-conductive insulating material such as plastic.

The fixing buckle 3 is made of a non-conductive insulating material, such as plastic, so that the light source plate 1 and the bottom plate 2 can be prevented from being conducted to enable the LED lamp beads 11 to emit light.

The locking portion 33 is deformable and elastic, and when the fixing buckle 3 is pressed to pass through the first through hole 12 and the second through hole 21, the locking portion 33 is deformable to pass through the first through hole 12 and the second through hole 21, and the locking portion 33 is restored after passing through the first through hole 12 and the second through hole 21, thereby fixing the light source plate 1 and the bottom plate 2.

Further, the lock portion 33 may be formed with a slope that faces away from the cap portion 32 and that tends toward the cap portion 32 more toward the radially outer side. The slope has a guiding function to allow the locking portion 33 to easily pass through the first through hole 12 and the second through hole 21.

Although the specific technical solutions of the present invention are explained in detail in the above specific embodiments, it should be also explained that:

(1) although the holder buckle 3 has three locking parts 33 in the above embodiment, the present invention is not limited thereto, and fewer or more locking parts 33 may be provided, for example, more (more than two) locking parts 33 may be provided between the light emitting panel 1 and the base panel 2, so that the distance between the light emitting panel 1 and the base panel 2 can be adjusted.

(2) Although the locking portion 3 has a ring shape in the above embodiment, the present invention is not limited thereto, and the locking portion 33 does not have to be formed in a ring shape around the entire circumference, and may be provided in the main body 31 so as to be spaced apart in the circumferential direction.
