[0024] Reference Figure 1-3 The image shown is a preferred embodiment of the present invention.

[0025] The Bluetooth communication controlled LED light source includes a circuit board 100 arranged in a ring, which surrounds a hollow region 101; the circuit board 100 is provided with a plurality of LED beads 200, which are electrically connected to the circuit board 100 and are arranged at intervals along the circumference of the circuit board 100; the circuit board 100 is provided with a Bluetooth element 300 for wireless communication with the outside; each LED bead 200 includes a substrate 201, which has a light-emitting area and a plurality of light-emitting chips 203.

[0026] The light-emitting chip 203 is an LED chip that can emit light when powered on. The circuit board 100 plays a control role. The Bluetooth component 300 can communicate wirelessly with external mobile terminals, etc. The circuit board 100 can be controlled by the mobile terminal, etc., to control the light emission of multiple LED beads 200.

[0027] The aforementioned Bluetooth communication controlled LED light source has a circuit board 100 arranged in a ring shape, with a hollow area 101 formed inside. Multiple LED beads 200 are arranged at intervals along the circumference of the circuit board 100, which facilitates the arrangement of multiple LED beads 200 in a ring shape to achieve the effect of uniform illumination of the entire circumference of the LED light source. Secondly, while meeting the installation requirements of multiple LED beads 200, the size design of the circuit board 100 is saved, the overall size design of the LED light source is optimized, the circuit board 100 is easy to install and connect with external components, and it occupies a small area.

[0028] In this embodiment, the circuit board 100 has multiple mounting positions, which are arranged circumferentially around the circuit board 100. The substrate 201 is fixed to the mounting positions by an adhesive layer and electrically connected to the circuit board 100 by a metal wire. In this way, the lamp bead 200 is fixedly mounted to the circuit board 100, and the light-emitting chip 203 is electrically connected to the circuit board 100.

[0029] In this embodiment, a rubber ring 202 is provided on the outer periphery of the substrate 201. The rubber ring 202 is arranged around the circumference of the substrate 201 and abuts against the circuit board 100. In this way, the outer periphery of the substrate 201 and the circuit board 100 are elastically abutted against each other through the rubber ring 202. When the LED light source is in a vibrating environment, the rubber ring 202 can be used to buffer the vibration on the outer periphery.

[0030] In this embodiment, the center of the substrate 201 is recessed downwards to form the aforementioned light-emitting area. The light-emitting area is recessed, and multiple light-emitting chips 203 are embedded in the light-emitting area. Forming a recessed light-emitting area facilitates the arrangement of multiple light-emitting chips 203 and facilitates subsequent processes such as dispensing.

[0031] In this embodiment, the light-emitting area is filled with a fluorescent adhesive layer 204, which covers multiple light-emitting chips 203. The light emitted by the light-emitting chips 203 passes through the fluorescent adhesive layer 204 to form the required illumination light and irradiates outward.

[0032] In this embodiment, a light-transmitting adhesive layer 205 covers the fluorescent adhesive layer 204, and the top of the fluorescent adhesive layer 204 has a top surface, which is covered by the light-transmitting adhesive layer 205. The light-transmitting adhesive layer 205 can seal and protect the top surface of the fluorescent adhesive layer 204, and can also focus the light emitted from the light-transmitting fluorescent adhesive layer 204.

[0033] In this embodiment, the middle part of the top surface is flat, forming a disc-shaped lower flat part 2041. The middle part of the lower flat part 2041 is recessed downward to form a recessed groove. The light-transmitting adhesive layer 205 covers the flat part and is embedded in the recessed groove.

[0034] This facilitates the bonding of the light-transmitting adhesive layer 205 and the fluorescent adhesive layer 204 into one unit. Furthermore, since the top surface has a flat lower part 2041 in the middle, it is easy for the light-transmitting adhesive layer 205 to be stacked on the fluorescent adhesive layer 204 in an arched shape, thereby achieving further light focusing.

[0035] In this embodiment, the light-transmitting adhesive layer 205 has a covering portion that covers the flat portion. The top of the covering portion is flat, forming a disc-shaped upper flat portion 2051. The diameter of the upper flat portion 2051 is smaller than the diameter of the lower flat portion 2041.

[0036] By forming the upper flat part 2051, light can be focused and irradiated after passing through the fluorescent adhesive layer 204, and the arrangement of the covering part is convenient.

[0037] In this embodiment, the outer periphery of the light-emitting area has an annularly arranged outer peripheral wall 2011. The outer peripheral wall 2011 is arranged around the outer periphery of the light-emitting area, and is inclined away from the light-emitting area along the upward direction of the light-emitting area. In this way, the light emitted from the side of the light-emitting chip 203 shines towards the outer peripheral wall 2011, and can be reflected by the outer peripheral wall 2011, and then shines outward through the phosphor layer 204, thereby achieving a high light efficiency.

[0038] In this embodiment, the circuit board 100 is provided with a connection position, and a through hole is provided in the connection position. A rubber sleeve 500 is inserted through the through hole and is integrally connected to the through hole. Two end rings 501 extend from the two ends of the rubber sleeve 500 and abut against the surface of the circuit board 100.

[0039] A fastener 400 is inserted through the rubber sleeve 500. After passing through the rubber sleeve 500, the fastener 400 is connected to the external component so that the circuit board 100 is connected to the external component. One end ring 501 abuts against the end of the fastener 400, and the other end ring 501 abuts against the external component, and the end ring 501 is under compression deformation.

[0040] In this way, the through hole is insulated by the rubber sleeve 500, and the fastener 400 is connected to the external component after passing through the rubber sleeve 500. Under the premise of achieving connection, the rubber sleeve 500 can achieve radial vibration buffering effect, and the two end rings 501 can achieve axial vibration buffering effect.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
