In order to make the above objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

As shown in fig. 1-7, the utility model provides an intelligent LED lamp strip, intelligent LED lamp strip includes:

the lamp bead installing structure comprises a pcb (printed circuit board) 1, wherein a plurality of installing areas 11 are arranged on the pcb 1 and used for installing lamp beads 2, and two first welding points 14 are arranged in the installing areas 11; and

LED lamp pearl 2, LED lamp pearl 2 is fixed installing zone 11, LED lamp pearl 2 includes support and light emitting source, be equipped with two first through-holes 21 of falling L type on the support, two first through-holes 21 cooperate with two respectively first solder joint 14, still be equipped with second solder joint 22 in the first through-hole 21, pour into tin cream into in the first through-hole 21, so that the support is fixed installing zone 11 and will first solder joint 14 with second solder joint 22 UNICOM, the light emitting source is fixed on the support, the light emitting source respectively with two second solder joint 22 UNICOM.

Specifically, the pcb 1 may be a simple circuit board, or a housing may be mounted outside the circuit board. Installing zone 11 can set up at the upper convex of pcb or recessed department, the central point of installing zone 11 puts the department and sets up second through-hole 12, the periphery of second through-hole 12 sets up two first solder joints 14, set up a movable groove on two lateral walls of installing zone 11 respectively, preferably two relative lateral walls, a fixed spring in the movable groove, the other end and the movable block 13 fixed connection of spring, under normal conditions, the spring has a thrust to movable block 13, make when installing LED lamp pearl 2, movable block 13 keeps off the below at LED lamp pearl 2. However, because the end of the movable block 13 close to the LED lamp bead 2 is an inclined plane, after the LED lamp bead 2 is continuously pressed downwards, the movable block 13 is pushed towards the movable groove until the LED lamp bead 2 reaches the bottom of the mounting area 11, at this time, the LED lamp bead 2 is rotated, and when the matching groove 23 faces the movable block 13, because of the lack of resistance, the movable block 13 is pushed by the spring to enter the matching groove 23, that is, the LED lamp bead 2 is preliminarily positioned. The two first through holes 21 of the LED lamp bead 2 are opposite to the two first welding points 14 on the p-mounting area 11. The luminous source generally comprises a luminous chip 4 and a fluorescent glue 3, wherein the luminous chip 4 is fixed in a luminous groove of the bracket and is connected with the two first welding points 14 through a conductive substance such as a copper strip, and the fluorescent glue 3 is fixed above the luminous chip 4. And injecting solder paste or other solders into the two first through holes 21, wherein the solder paste overflows the second welding points 22, and the solder paste is fixedly formed after reflow soldering, so that the first welding points 14 and the second welding points 22 are conducted through the solder paste. After being connected with the power supply, the pcb board 1, the bracket and the light emitting source are connected with each other through a conducting circuit. As can be seen from the above, the movable block 13 is matched with the matching groove 23, so that the bracket can be positioned, and the phenomenon that the solder paste between the two first welding points 14 is connected together due to the displacement or rotation of the bracket in the operation process is avoided; the first through holes 21 are arranged, so that solder paste can be injected into the first through holes 21, the first welding points 14 are connected with the second welding points 22, and unlike the conventional lamp beads which are directly pressed on the solder paste, the solder paste is easy to diffuse to the periphery; and installing zone 11 sets up second through-hole 12, is in order to install LED lamp pearl 2 back, and the LED lamp pearl 2 heat dissipation of being convenient for prolongs LED lamp pearl 2's life.

In some embodiments, a second through hole 12 is formed in the center of the mounting area 11, so that the LED lamp bead 2 can dissipate heat conveniently.

In some embodiments, two movable slots are further disposed on the mounting region 11, and a spring is further fixed in the movable slot.

In some embodiments, a movable block 13 is further disposed on the movable groove, the movable block 13 is fixedly connected with the spring, and the movable block can move in and out of the movable groove.

Specifically, the spring always has a pushing force on the movable block 13, so that the movable block 13 can be quickly clamped into the matching groove 23 when meeting the matching groove 23. Simultaneously in order to prevent that the movable block 13 from breaking away from the unstable condition in movable groove, this embodiment sets up a recess again at the top surface in movable groove, then sets up a convex body on the top surface of movable block 13, and convex body and recess cooperate for the convex body can the seesaw in the recess, but can not break away from the recess, even under the thrust effect of spring, movable block 13 also can not separate with movable groove.

In some embodiments, an inclined surface is arranged at one end of the movable block 13 close to the LED lamp bead 2.

Specifically, there may be an inclined plane at the upper end of the movable block 13 near the end of the LED lamp bead 2, or the entire end may be an inclined plane.

In some embodiments, a light emitting groove is formed at a central position of the upper end of the bracket, and the light emitting source is fixed in the light emitting groove.

In some embodiments, two fitting grooves 23 are further formed at the edge of the upper end of the bracket, and the two fitting grooves 23 are respectively fitted with the two movable blocks 13.

In some embodiments, the light emitting source includes a light emitting chip 4 and a fluorescent glue 3, the light emitting chip 4 is fixed in the light emitting groove and is respectively communicated with the two second pads 22, and the fluorescent glue 3 is disposed above the light emitting chip 4.
