Description
Technical Field
[0001] The utility model belongs to the technical field of LED light strips, and in particular relates to a flicker-free and driver-free high-voltage light strip. Background Art
[0002] Existing high-voltage light strips require either a plug or a bridge rectifier on the FPCB to suppress some flicker, but flicker is still visible to the naked eye when using a mobile phone or to some people. Furthermore, the plug-in method is difficult to install due to its large size and the need to distinguish between positive and negative poles, as well as being costly. The FPCB with a bridge rectifier requires relatively fine circuitry and high process requirements, and the FPCB is larger than the design of the invented product. To address the above issues, a flicker-free, driver-free high-voltage light strip is provided. Utility Model Content
[0003] In order to solve the defects and shortcomings of the existing technology, the purpose of the present invention is to provide a flicker-free and driver-free high-voltage light strip with a simple structure, reasonable design, and easy use. It optimizes the application circuit to achieve driver-free and flicker-free. The circuit optimization can also eliminate the bridge stack of the FPCB board and solve the sine wave changes caused by the AC mains.
[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: it includes a combined light strip, components, and a fixed resistor; several combined light strips are connected to the power supply neutral and live wires, and the combined light strips are composed of an array component and several fixed resistors connected in series; the components are composed of a forward diode and a reverse diode connected in parallel, the positive pole of the forward diode is connected to the negative pole of the reverse diode, and the negative pole of the forward diode is connected to the positive pole of the reverse diode.
[0005] Preferably, the forward diode and the reverse diode maintain the same structure and specifications.
[0006] Preferably, the combined light strip can also be composed of a forward light-emitting component and a reverse light-emitting component connected in parallel, wherein the forward light-emitting component is composed of several forward diodes and several fixed resistors connected in series; the reverse light-emitting component is composed of several reverse diodes and several fixed resistors connected in series.
[0007] Preferably, the number of forward diodes and reverse diodes in the forward light-emitting component and the reverse light-emitting component is consistent.
[0008] After adopting the above structure, the beneficial effects of the utility model are: it optimizes the circuit structure, improves the practical ability of the product, is easy to install, simple to operate, does not waste materials, saves labor time, materials and costs, improves luminous efficiency and life, and solves the application mode of no plug and no bridge stack, making the product more convenient and more cost-effective to use, and also eliminates the safety hazards caused by explosion, sparking and fire due to reverse connection of the bridge stack or reverse mounting of the patch bridge stack.

[0013] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is described below using specific embodiments illustrated in the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention.

[0015] See Figure 1 As shown, this specific embodiment adopts the following technical solution: it includes a combined light strip A, an LED component B, and a fixed resistor R; several combined light strips A are connected to the power supply neutral and live wires, and the combined light strip A is composed of an array of LED components B and several fixed resistors R connected in series; the LED component B is composed of a forward diode LED1 and a reverse diode LED2 in parallel, the positive pole of the forward diode LED1 is connected to the negative pole of the reverse diode LED2, and the negative pole of the forward diode LED1 is connected to the positive pole of the reverse diode LED2.
[0016] Preferably, the forward diode LED1 and the reverse diode LED2 maintain the same structure and specifications. Specific implementation method 2:
[0018] See Figure 2 As shown, the difference between this specific embodiment and the specific embodiment is that: the combined light strip A is composed of a forward LED light-emitting component C and a reverse LED light-emitting component D in parallel, wherein the forward LED light-emitting component C is composed of several forward diodes LED1 and several fixed resistors R in cross-series; the reverse LED light-emitting component D is composed of several reverse diodes LED2 and several fixed resistors R in cross-series; the number of forward diodes LED1 and reverse diodes LED2 in the forward LED light-emitting component C and the reverse LED light-emitting component D is consistent.
[0019] The working principle of this specific embodiment is as follows: this specific embodiment adopts the unidirectional conductive characteristics of the diode (lamp bead), and the positive half-cycle circuit light-emitting diode is turned on in the positive half-cycle of the sine wave, and the negative half-cycle circuit light-emitting diode is turned on in the negative half-cycle, so the positive and negative half-cycle waveforms are complementary, which proves that it can achieve a flicker-free and drive-free application; There are three ways to implement this scheme in practice: the first is to package the lamp bead, and the same chip is packaged in parallel in one positive and one negative in the lamp bead bracket, and the circuit is designed to be parallel first and then series; the second is to mount two lamp beads in parallel, one positive and one negative, and the circuit is designed to be parallel first and then series; both the first and the second use Figure 1 Connection method: The third method is to mount one of the positive direction mounting circuits in series, and the other set of reverse direction mounting circuits in series. Finally, connect the positive pole of one end in the forward direction and the negative pole of the reverse direction mounting in parallel, and connect the reverse pole of one end in the reverse direction and the positive pole of the other end in parallel to achieve flicker-free and drive-free application.
