[0029] In order to make the technical scheme of the utility model more clear, the utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0030] Embodiment 1

[0031] In combination with the drawings Figure 2 A LED lamp bead structure beneficial to glue dispensing, the glue dispensing structure is composed of a bottom plate 10 and a side plate 11, a lamp bead chip 12 is installed on the bottom plate 10, the side plate 11 is arranged around the bottom plate 10, the lamp bead chip 12 is installed at the geometric center of the bottom plate 10, the side plate 11 on the bottom plate 10 is arranged around the lamp bead chip 12, and the outer side of the side plate 11 is aligned with the side of the bottom plate 10.

[0032] The bottom plate 10 is a square structure or a circular structure, and the side plate 11 is arranged around the upper surface of the bottom plate 10 and changes in shape in correspondence with the shape of the bottom plate 10.

[0033] When the bottom plate 10 is square, the side plate 11 is formed by vertically connecting four identical side plates end to end, and the four side plates 11 are arranged along the square lines on the surface of the bottom plate 10, and the outer side of the side plate 11 is aligned with the square lines of the bottom plate 10 at this time.

[0034] When the bottom plate 10 is circular, the side plate 11 is arranged in a ring shape on the bottom plate 10 in a ring structure, the side plate 11 as a whole is a ring structure, and the outer side of the side plate 11 is aligned with the circular lines of the bottom plate 10 at this time.

[0035] The side plate 11 is arranged around the lamp bead chip 12 on the bottom plate, thereby forming a glue groove 13 capable of accommodating glue, and the lamp bead chip 12 is arranged at the center position of the glue groove.

[0036] The side of the side plate 11 facing the lamp bead chip 12 is composed of two inclined surfaces with different angles, and the two inclined surfaces on the side of the side plate 11 facing the lamp bead chip 12 are used when dispensing glue. The glue slides down through the inclined surfaces on the side plate 11, thereby being filled into the glue groove 13 formed by the side plate 11. By filling the glue into the glue groove 13, the lamp bead chip 12 located in the glue groove 13 and fixed on the bottom plate 10 is fixed by the glue, and the lamp bead chip 12 is protected.

[0037] The two inclined surfaces of the side plate 11 are respectively a first inclined surface located on the lower side of the side plate 11 and a second inclined surface connected to the first inclined surface on the upper side of the side plate 11, and the first inclined surface further extends in the direction of the lamp bead chip 12 relative to the second inclined surface.

[0038] An angle R1 is formed between the first inclined surface on one side plate 11 and the first inclined surface on the symmetrically opposite side plate 11, and the value of the angle R1 ranges from 0 to 55 degrees. When the angle R1 is 0 degrees, the first inclined surfaces on both sides are parallel.

[0039] The second slope on one side plate 11 forms an angle R2 with the second slope on the symmetric side plate 11 on the other side, and the angle R2 ranges from 150 to 180 degrees, and when the angle R2 is 180 degrees, it means that the second slopes on both sides are on the same plane.

[0040] The height of the first slope from the surface of the bottom plate 10 is H1, and the height of the second slope on the first slope is H2, and the relationship between H1 and H2 is that H2 is between 0.5 times H1 and 1 times H1, and the first slope is used for dispensing glue, and the glue needle will dispense glue to the side of the first slope close to the second slope, which is used for temporarily placing glue, and the second slope is used to assist the glue to slide along the slope of the second slope, which is used to assist the glue to fill the glue groove 13.

[0041] The width of the side plate 11 is C1, and in addition to the width formed by the first slope and the second slope, there is a flat thickness C2 with a flat surface, and the relationship between C1 and C2 is that C2 is between 0.2 times C1 and 0.5 times C1.

[0042] A round corner is provided between the first slope and the second slope to facilitate the flow of glue.

[0043] The lamp bead chip 12 and the bottom plate 10 can be integrally formed by injection molding, or the lamp bead chip 12 can be fixed on the bottom plate 10 by drilling holes in the bottom plate 10.

[0044] The lamp bead chip 12 is provided with a wire connected to the bottom plate 10, so as to facilitate power supply and control of the lamp bead chip 12, and to realize the lighting and turning off of the lamp bead as a whole.

[0045] In use, only the dispensing pillow needs to be moved to the second slope on the side plate 11 on either side, and the pillow is correspondingly arranged at the position close to the first slope on the second slope, and after dispensing glue, the glue first flows on the second slope, and since the inclination angle of the second slope is smaller than that of the first slope, the glue on the second slope flows slowly on the second slope, and when the glue reaches the first slope, the glue flows faster, and the glue flows along the first slope to the glue groove 13, at this time the glue can cover the lamp bead chip 12, and since the glue gradually transitions from one side of the glue groove 13 to the other side of the glue groove 13 along the second slope on one side, the glue flows down along the side wall, which can improve the bottom bubble phenomenon, increase the opening area on the basis of little change in the strength of the side wall, improve the process window, and improve the point deviation problem.

[0046] It is suitable for various dispensing lamp beads, and the bottom can be a wire bonding chip or a flip chip. It is particularly suitable for dispensing lamp beads for GOB products.

[0047] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several deformations and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
