[0077] Infrared LED chips 120 and white light LED chips 121, wherein the infrared LED chips 120 and the white light LED chips 121 are alternately mounted in the crystal bonding grooves 202;

[0079] An insulating ring 501, wherein the insulating ring 501 is mounted on the top of the anode ring 401;

[0080] A cathode ring 601, wherein a cathode copper foil 602 extending inward is arranged on the inner side wall of the cathode ring 601, and the cathode copper foil 602 cooperates with the connection groove 203. A second connection copper foil 603 is arranged on the top of the cathode ring 601, and the second connection copper foil 603 is installed on the side groove 105 and the vertical groove 106. The cathode ring 601 is fixedly installed in the first installation groove 102 and arranged on the top of the insulating ring 501. The cathode ring 601 is electrically connected to the infrared LED chip 120 and the white light LED chip 121 and is insulated from the anode ring 401.

[0081] A light shielding ring 701, wherein the light shielding ring 701 is provided with a light-transmitting hole 702, and the light shielding ring 701 is fixedly installed on the first mounting groove 102. When the light shielding ring 701 is not provided, a colloid is generally filled for fixing and sealing;

[0082] A lens 801, wherein the lens 801 is fixedly mounted in the light-transmitting hole 702;

[0083] A welding plate 901, wherein the welding plate 901 is provided with a through slot 902, and at least two notches 903 are provided on the top of the welding plate 901, and the base 101 is fixedly installed in the through slot 902;

[0084] The welding piece 904 is fixedly installed in the notch 903 , and the welding piece 904 is electrically connected to the anode ring 401 and the cathode ring 601 respectively.

[0085] It should be pointed out that in order to solve the problems of non-true color, blurred imaging, small imaging range and width of infrared night vision camera imaging in night vision lighting of security cameras, the infrared LED chip 120 and the white light LED chip 121 are arranged alternately and in the same quantity to improve the light mixing effect, thereby improving the overall imaging quality and the width of the observable area, which is more efficient and of higher quality than the traditional parallel arrangement. Through the combination of multiple low-power chips and the above structure, the heat can be dispersed at the edge as much as possible, thereby improving the heat dissipation; and according to the needs, the wiring method of the anode ring 401 can be adjusted to divide the anode ring 401 into two parts, one part connected to the infrared LED chip 120, and the other part connected to the white light LED chip 121, so as to realize the external single drive of all the infrared LED chips 120 or all the white light LED chips 121, thereby realizing the function of coordinated lighting or only lighting, thereby saving electric energy.

[0086] It should be noted that the infrared LED chip 120 and the white light LED chip 121 are welded to the anode copper foil 402 and the cathode copper foil 602 through gold wire or conductive wire; the infrared LED chip 120 and the white light LED chip 121 are not suspended and installed in the solid crystal groove 202, and the solid crystal groove 202 is used to limit the horizontal movement of the infrared LED chip 120 and the white light LED chip 121. Generally speaking, the infrared LED chip 120 and the white light LED chip 121 are fixed by snapping or glue; the material of the base 101 is non-metallic material, such as ceramic. The purpose of setting the side groove 105 and the vertical groove 106 is to facilitate the fixed installation of the first connecting copper foil 403 and the second connecting copper foil 603, while leaving a contact surface for easy connection with an external circuit. When the light shielding ring 701 is made of plastic, welding cannot be performed on the top surface of the light shielding ring 701 or the side surface of the base 101 to avoid melting the light shielding ring 701. In this case, welding needs to be performed on the welding sheet 904 that is matched with the welding disk 901. The welding disk 901 is generally fixed to the base 101 by interference fit or snap-fit, and the welding sheet 904 is horizontally arranged with a relatively large contact surface, which can be welded more conveniently and quickly. The function of the lens 801 is to seal and adjust the light effect of the plurality of infrared LED chips 120 and the white light LED chips 121 emitting light together.

[0087] It should be noted that the anode ring 401 and the cathode ring 601 are separated by the insulating ring 501 to achieve insulation and avoid short circuit. At the same time, the first connecting copper foil 403 and the second connecting copper foil 603 are generally arranged in different grooves and can be arranged symmetrically, such as Figure 1 As shown. This can avoid opening holes on the side of the base 101, thereby ensuring sealing and reducing production difficulty. The function of the light shielding ring 701 is mainly to cut light and facilitate the installation of the lens 801. The function of the chip bracket 201 is to facilitate the arrangement, welding, and fixing of the infrared LED chip 120 and the white light LED chip 121 to improve stability.

[0088] Specifically, Figure 2 , Figure 4As shown, another embodiment further includes: a press frame 301, the press frame 301 is provided with a support arm 302, the outer end of the support arm 302 is provided with a matching flange 303, the matching flange 303 is matched with the solid crystal through groove 202, and the bottom of the press frame 301 is provided with a fixing protrusion 304; the top of the chip holder 201 is provided with a fixing groove 204, the fixing groove 204 is matched with the fixing protrusion 304, the press frame 301 is fixedly installed on the top of the chip holder 201 and fixes the infrared LED chip 120 and the white light LED chip 121 to the bottom of the solid crystal through groove 202. When the infrared LED chip 120 and the white light LED chip 121 cannot be fixed by using colloid, the infrared LED chip 120 and the white light LED chip 121 are effectively fixed by using the press frame 301 in combination with the chip holder 201.

[0089] Specifically, Figure 2 , Figure 4 As shown, there is another embodiment in which a second mounting groove 103 is provided at the bottom of the first mounting groove 102, and a mounting through groove 104 is provided at the bottom of the second mounting groove 103; it also includes: a heat dissipation copper seat 110, the heat dissipation copper seat 110 is provided with a step 111, the step 111 cooperates with the second mounting groove 103, the bottom of the infrared LED chip 120 and the white light LED chip 121 are closely attached to the top surface of the heat dissipation copper seat 110, and the heat dissipation copper seat 110 is fixedly installed in the mounting through groove 104. It should be noted that the bottom surface of the heat dissipation copper seat 110 is flush with or slightly lower than the bottom surface of the base 101, and then cooperates with silicone grease to achieve better contact on the radiator and improve heat dissipation efficiency; the bottom surfaces of the infrared LED chip 120 and the white light LED chip 121 are directly dissipated on the heat dissipation copper seat 110, and then cooperate with the base 101 to dissipate heat.

[0090] Specifically, Figure 2 As shown, the insulating ring 501 is provided with a first matching notch 502, and the first matching notch 502 matches with the first connecting copper foil 403; the cathode ring 601 is provided with a second matching notch 605, and the second matching notch 605 matches with the first connecting copper foil 403 for easy installation.

[0091] Specifically, Figure 2 , Figure 3 As shown, the first connecting copper foil 403 and the second connecting copper foil 603 are U-shaped and are inverted on the side groove 105 and the vertical groove 106 to facilitate fixed installation and connection with an external circuit.

[0092] Specifically, Figure 2-Figure 7As shown, the first connecting copper foil 403 is provided with a first groove 404 on its outer wall, and the second connecting copper foil 603 is provided with a second groove 604 on its outer wall; the inner wall of the welding sheet 904 is provided with a clamping flange 905, and the clamping flange 905 is clamped with the first groove 404 and the second groove 604. The function is to facilitate the welding plate 901 to fix the base 101 on the heat sink together. The welding plate 901 is generally provided with a fixing screw hole 906 for fixing on the heat sink. The base 101 is fixed on the welding plate 901 through the clamping flange 905 and the first groove 404 and the second groove 604 and is electrically connected. Furthermore, a welding groove 703 cooperating with the first connecting copper foil 403 and the second connecting copper foil 603 is provided on the top of the shading ring 701. When the shading ring 701 is made of heat-resistant material and electrical connection is required on the top surface, welding can be conveniently performed through the welding groove 703.

[0093] It should be pointed out that a flange 704 is provided on the inner wall of the light-transmitting hole 702, and the flange 704 is used to cooperate and fix the lens 801. The length of the cathode copper foil 602 is greater than or equal to the length of the anode copper foil 402, so as to avoid the solder on the cathode copper foil 602 set on it dripping onto the anode copper foil 402 during welding to cause a short circuit, and then different lengths are set for staggering. Generally speaking, the crystal-fixing through grooves 202 are provided with six and arranged in a circular array, and the infrared LED chips 120 and the white light LED chips 121 are provided with six and installed alternately. At this time, the heat is mainly concentrated on the edge of the heat dissipation copper seat 110 and the inner edge of the first installation groove 102, which is more conducive to heat dissipation and the arrangement of more infrared LED chips 120 and the white light LED chips 121 than the central part of the heat dissipation copper seat 110.

[0094] In summary, the present invention connects the white light LED chip 121, the infrared LED chip 120, the base 101, the chip bracket 201, the anode ring 401, the insulating ring 501, the cathode ring 601 and other components together through an ingenious structure, thereby ensuring that the lamp beads can achieve sufficient heat dissipation, and alternately installing the white light LED chip and the infrared LED chip on the chip bracket, thereby achieving a better mixed light effect and lighting width, allowing security cameras to capture better pictures, and effectively avoiding the occurrence of cold soldering and breakage of gold wires, and improving the heat dissipation effect to increase the service life and reduce light decay, while facilitating assembly and production. The above greatly improves the practical value of the present invention.
