Description

Technical Field

[0001] The utility model relates to the field of LED lamp beads, in particular to a through-type LED bracket and an LED lamp bead. Background Art

[0002] Traditional LED brackets are mostly left-right structures, with the bracket metal strips separated on the left and right. When the lamp beads are packaged, one side is positive and the other side is negative. The chip packaged in a single bracket is relatively fixed, with poor compatibility and low scalability. In actual use, it is difficult to wire the single-sided aluminum substrate, and it is difficult to connect the lines in parallel first and then in series, resulting in low stability of the lamp, and it is easy to have dead lights, causing the entire lamp to be partially off, or even not at all. Utility Model Content

[0003] One purpose of the utility model is to provide a through-type LED bracket to solve the technical problem that the metal strips of the traditional LED bracket are separated into left and right parts, which makes it difficult to connect the circuits in parallel first and then in series, resulting in low stability of the lamp.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide a through-type LED bracket, which is applied to an LED lamp, and the through-type LED bracket comprises:

[0005] A base, wherein a top of the base is provided with an inwardly concave cup mouth;

[0006] A plurality of pins are provided, wherein the pins penetrate the base, the warp of the middle area of ​​the pins is located in the cup mouth of the base, and the pins are arranged side by side; and both ends of the pins are bent downward to be aligned with the bottom surface of the base.

[0007] In one embodiment, the outer edge of the cup mouth is a wavy curved surface.

[0008] In one embodiment, the pins are made of conductive metal material.

[0009] In one embodiment, the base is made of polyethylene material.

[0010] In one embodiment, the widths of the warp threads are different.

[0011] Another object of the present utility model is to provide an LED lamp bead, comprising a through-type LED bracket as described in any one of the above embodiments.

[0012] In one embodiment, a plurality of LED chips are further included, and each of the LED chips is connected to the pins in parallel.

[0013] One or more of the above technical solutions in the embodiments of the present utility model have at least the following technical effects or advantages:

[0014] The through-type LED bracket provided by the embodiment of the utility model leads out all the pins of the LED bracket and the warp of the pins runs through left and right so that the left and right sides have the same pins. When designing the circuit board, it is easy to realize that the lamp bead circuits are first connected in parallel and then in series (the LED chips are connected in parallel in the warp area of ​​the pins). When one of the LED chips in the lamp bead fails (such as burning out and opening the circuit), since the LED chips are connected in parallel first and then in series, the failure of individual LED chips will not affect the normal operation of other LED chips, so that the remaining LED chips can emit light normally, and the whole lamp will not be partially dark or the whole lamp will not be dark, thereby improving the stability of the LED lamp.

[0024] See also Figure 1 The embodiment of the present application provides a through-type LED bracket, comprising a base 1 and a plurality of pins 2. The top of the base 1 is provided with an inwardly recessed cup 11; the pins 2 penetrate the base 1, and the warp 21 of the middle area of ​​the pins 2 is located in the cup 11 of the base 1, and the pins 2 are arranged side by side; the two ends of the pins 2 are bent downward to align with the bottom surface of the base 1.

[0025] By leading out all the pins 2 of the LED bracket and the warp 21 of the pin 2 running through the left and right sides, so that the left and right sides have the same pin 2, when designing the circuit board, it is easy to realize that the lamp bead circuit is first connected in parallel and then in series (the LED chip is connected in parallel in the warp 21 area of ​​the pin 2), so that when one of the LED chips in the lamp bead fails (such as burning out and opening the circuit), since the LED chips are connected in parallel first and then in series, the failure of individual LED chips will not affect the normal operation of other LED chips, so that the remaining LED chips can emit light normally, and the whole lamp will not be partially dark or the whole lamp will not be dark, thereby improving the stability of the LED lamp.

[0026] In one embodiment, the outer edge of the cup mouth 11 is a wavy curved surface. The wavy outer edge of the cup mouth 11 is not only beautiful, but also helps to improve the bonding strength between the encapsulating colloid 3 and the base 1, reducing the probability of debonding during subsequent use of the lamp.

[0027] In one embodiment, the pin 2 is made of a conductive metal material, for example, copper, tungsten, or nickel-iron alloy.

[0028] In one embodiment, the base 1 is made of polyethylene material, which has good insulation and corrosion resistance.

[0029] In one embodiment, the widths of the warps 21 are different. Warps 21 of different widths can meet different current requirements, optimize the circuit design of the LED bracket, and easily realize multiple specifications of chips and perform simultaneous packaging.

[0030] Another object of the present utility model is to provide an LED lamp bead, comprising a through-type LED bracket as described in any one of the above embodiments.

[0031] In one embodiment, a plurality of LED chips are further included, and each LED chip is connected in parallel to the pin 2. By adopting the parallel connection mode, the entire lamp can still maintain normal light emission when a chip fails, thereby improving the reliability of the LED lamp.

[0032] like Figure 2 As shown, the cup mouth 11 is filled with a transparent encapsulating colloid 3, which covers the LED chip and has a hemispherical shape. The hemispherical encapsulating colloid 3 can focus light, reduce the luminous angle, and enhance the brightness in the top direction.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
