Description

Technical Field

[0001] The present invention relates to the technical field of COB light strips, and in particular to a COB light strip and an RGB controller plug applied to the COB light strip. Background Art

[0002] COB light strip refers to a lighting device that uses COB technology to directly package multiple LED chips on a flexible circuit board. This packaging method makes the COB light strip have the characteristics of high brightness, high color rendering, and uniform lighting.

[0003] At present, the specifications of previous SMD light strips are mostly 60 lights and 10mm wide. The four wires of the connector have enough space for contact pins, and the distance between each wire end of the 10mm wide circuit board is about 0.2mm, which can be used as a controller plug accessory. However, for COB light strips with a 10mm wide circuit board, the middle colloid occupies about 4mm of space, leaving only 6mm of width on both sides, and only about 1.5mm on one side needs to be divided equally by two pins. The space is too small to be used as an accessory plug, which makes the existing COB light strips very inconvenient during installation and use.

[0008] Beneficial effects of the present invention:

[0009] The present invention provides a COB light strip and an RGB controller plug for the COB light strip. By providing a packaging colloid, a chip and a groove, when the COB light strip is lit, since the outer wall of the packaging colloid at the top of the flexible circuit board is provided with grooves distributed at equal distances, the light emitted by the chip is cross-reflected through the grooves, thereby forming cross-light spots, thereby making the light of the entire COB light strip more continuous. At the same time, the cross-light spots distributed at equal distances formed by multiple groups of grooves can reduce the arrangement density of the chips on the flexible circuit board, reduce the production cost of the COB light strip, and will not affect the continuity of the entire COB light strip. The groove includes an isosceles trapezoidal portion and an arc portion. Since the top of the packaging colloid is gradually away from the chip (light source), the opening angle of the isosceles trapezoidal portion is gradually increased from bottom to top, thereby making up for the lack of brightness of the light source far away from the chip. At the same time, the area closest to the chip (light source) is an arc portion, which can expand the divergence range of the light source. The two sides of the groove do not all penetrate the outer wall of the packaging colloid, which can prevent the light source from being lost from the left and right sides of the groove, thereby ensuring the brightness and continuity of the entire COB light strip.

[0010] A COB light strip and an RGB controller plug applied to the COB light strip provided by the present invention can effectively ensure the tightness of the connection between the encapsulated colloid and the flexible circuit board. Specifically, by opening equidistantly distributed glue dispensing grooves on the flexible circuit board, the colloid can be filled into the flexible circuit board to form an integrated body, thereby ensuring the stability of the encapsulated colloid. At the same time, the glue dispensing grooves are arranged on both sides of the chip. At this time, the matching colloid filled in the glue dispensing grooves can be used to reinforce both sides of the chip, so that a bending damping zone is formed at the chip, thereby preventing the COB light strip from damaging the chip during the bending process. The glue dispensing groove forms a bamboo structure by thickening the groove portion and the node groove portion, thereby improving the folding resistance of the matching colloid.

[0011] The present invention provides a COB light strip and an RGB controller plug for the COB light strip. Through the male and female connectors, when the staff needs to connect the COB light strip to the RGB controller body, the staff can insert the female connector at one end of the connector into the male connector at one end of the RGB controller body. Before the female connector is inserted into the male connector, one end of the positioning ball is blocked by the baffle and remains stable. Then, as the female connector is inserted into the second extension plate, the second ring plate is squeezed into the annular cavity. During the squeezing process of the second ring plate, the baffle is driven to move together. When the baffle moves to a certain extent, it will separate from the positioning ball. At this time, the first spring in the fixed tube in a compressed state will immediately restore its deformation to eject the positioning ball. The positioning ball will be snapped into the positioning groove of the outer wall of the first extended ring plate, thereby achieving stability after the male and female heads are connected and installed. When the staff needs to separate the male and female heads, the staff can rotate the annular column, and the convex ring plate can be driven to rotate through the annular column until the convex ring part in the convex ring plate rotates to contact the rollers. At this time, the sliding column can be pushed outward by the convex ring part, so that the positioning ball can be disengaged from the positioning groove. The staff only needs to pull the female head out of the male head to achieve quick disassembly and separation, and the second spring in the compressed state inside the annular cavity will immediately reset and apply elastic force to the second slide plate to reset it. At this time, the positioning ball can be blocked and limited again by the baffle, which is convenient for the subsequent cyclic plugging and unplugging of the female head.

[0037] In summary, with the help of the above technical solution of the present invention, when the staff needs to light up the COB light strip, they can light up the chip 4 on the flexible circuit board 1, wherein each three groups of chips 4 display red, blue and green respectively, and by controlling the brightness of the three groups of chips 4, color light can be effectively changed to meet people's use needs in different environments. When the COB light strip is lit, since the outer wall of the packaging colloid 2 on the top of the flexible circuit board 1 is provided with grooves 3 distributed at equal distances, the light emitted by the chip 4 is cross-reflected through the grooves 3, thereby forming cross-light spots, thereby making the light of the entire COB light strip more continuous.

The production cost of the COB light strip is reduced, and the continuity of the entire COB light strip is not affected. The groove 3 includes an isosceles trapezoidal portion 3001 and an arc portion 3002. As the top of the encapsulation colloid 2 gradually moves away from the chip 4 (light source), the opening angle of the isosceles trapezoidal portion 3001 gradually increases from bottom to top, thereby making up for the insufficient brightness of the light source far away from the chip 4. At the same time, the area closest to the chip 4 (light source) is the arc portion 3002, which can expand the divergence range of the light source. The two sides of the groove 3 do not all penetrate the outer wall of the encapsulation colloid 2, which can prevent the light source from being lost from the left and right sides of the groove 3, thereby ensuring the brightness and continuity of the entire COB light strip. In order to ensure the tightness of the connection between the encapsulation colloid 2 and the flexible circuit board 1, the COB light strip is By opening the glue dispensing grooves 6 distributed at equal distances on the flexible circuit board 1, the colloid can be filled into the flexible circuit board 1 to form an integrated whole, thereby ensuring the stability of the packaged colloid 2. At the same time, the glue dispensing grooves 6 are arranged on both sides of the chip 4. At this time, the matching colloid 7 filled in the glue dispensing grooves 6 can be used to reinforce both sides of the chip 4, so that a bending damping zone is formed at the chip 4, thereby preventing the COB light strip from damaging the chip 4 during the bending process. The glue dispensing grooves 6 form a bamboo structure by thickening the groove portion 6001 and the node groove portion 6002, thereby improving the folding resistance of the matching colloid 7. When the staff needs to connect the COB light strip to the RGB controller body 11, the staff can insert the female head 9 at one end of the connector 8 into the RGB controller body 11, before the female head 9 is inserted into the male head 12, one end of the positioning ball 39 is blocked by the baffle 38 and remains stable. Then, as the female head 9 is inserted into the second extension plate, the second ring plate is squeezed into the annular cavity 29. In the process of squeezing the second ring plate, the baffle 38 will be driven to move together. When the baffle 38 moves to a certain extent, it will separate from the positioning ball 39. At this time, the first spring 35 in the fixed cylinder 25 in a compressed state will immediately restore the deformation to eject the positioning ball 39. The ejected positioning ball 39 will be snapped into the positioning groove 40 on the outer wall of the first extension ring plate 41, thereby achieving stability after the male head 12 and the female head 9 are docked and installed. When the staff needs to separate the male head 12 and the female head 9, the staff can rotate the annular column 19,The annular column 19 can drive the convex ring plate 24 to rotate until the convex ring portion 2401 in the convex ring plate 24 rotates to contact the roller 23. At this time, the slide column 20 can be pushed outward by the convex ring portion 2401, so that the positioning ball 39 can be separated from the positioning groove 40. The staff only needs to pull the female head 9 out of the male head 12 to achieve rapid disassembly and separation. The second spring 36 in the compressed state inside the annular cavity 29 will immediately reset and apply elastic force to the second slide plate 37 to reset it. At this time, the baffle 38 can block and limit the positioning ball 39 again, which is convenient for the subsequent cyclic plugging and unplugging of the female head 9.
