Description
Technical Field
[0001] The utility model relates to the field of LEDs, in particular to a double-color LED soft light strip that can be cut into short sizes at will. Background Art
[0002] With the development of LED lighting technology, LED light strips are becoming more and more popular. However, due to the limitations of their structure, in long-distance light strip applications, two-color or multi-color light strips are processed according to the traditional one-color-one-way method, which not only makes the structure bulky, but also increases the number of lines used, the cost also increases, and it cannot be cut and used at will. Even if the so-called randomly cut light strips appear on the market in the later period, they are also 1 meter cut light strips. That is, even if the actual length is 5.2 meters, the light strip needs to be cut to 6 meters, which causes great waste and inconvenience. In addition, if two colors need to be controlled separately in the current 1 meter cut LED light strip, two single-color temperature lamp beads need to be used, with 60 pure white lamp beads and 60 warm white lamp beads per meter. The power per meter of the light strip will be low, the luminous flux per meter will also be low, and the dark area of the light will be more obvious. Therefore, it is necessary to develop a multi-color LED light strip, which can not only solve the problem of the light strip becoming larger in size when it is two-color, but also can achieve short size (less than 20cm) and be cut and used at will, and solve the problem of poor brightness of the head and tail parts under long distance conditions. Summary of the invention
[0003] The purpose of the utility model is to improve the deficiencies of the prior art. The beneficial effects of the utility model are: providing a multi-color LED light strip, which can not only solve the problem of the light strip becoming larger in size when it is two-color, but also can realize short-size (less than 20cm) arbitrarily cut and used, and solve the problem of poor brightness of the head and tail parts under long distance conditions, and can also realize direct connection to civil mains for use.
[0004] The utility model is a two-color LED soft light strip that can be cut into short sizes at will, which is mainly composed of an insulating substrate with LED lamp beads, electrical components and laying circuits, a transparent or translucent light-transmitting insulating layer wrapping the insulating substrate, and a plurality of main circuit units connected in series on the insulating substrate, each of which has a length of 5cm-15cm. The LED lamp beads use SMD two-color temperature lamp beads. In this way, it can be cut into short sizes (less than 20cm) at will, and the soft light strip can be miniaturized, which is convenient to use and reduces unnecessary consumption.
[0005] Furthermore, the utility model discloses a two-color LED soft light strip that can be cut to any length, and each main circuit unit is provided with two interfaces for connecting to the civil mains (the common civil mains is AC 220V or AC 110V), so that it can be directly connected to the civil mains for use. In addition, due to the reasonable circuit design and the clever use of components, the width of the soft light strip can be greatly reduced, and the width of the insulating substrate is 8cm-12cm. It is convenient to use in narrow spaces.
[0006] Furthermore, the utility model discloses a dual-color LED soft light strip that can be cut to any size, wherein the main circuit unit includes: two parallel rectangular strips of copper foil for connecting to the civil mains power supply are attached to the insulating substrate and distributed at both ends of the components of each main circuit unit, and the ends of the two copper foils are respectively connected to the input end of the rectifier bridge, and the positive output end of the rectifier bridge output end is divided into two outputs, one of which is connected in series with the third resistor and then connected to the VIN pin of the TC3085HB integrated block; the other is connected to the input end of a plurality of SMD dual-color temperature lamp beads in series, and a plurality of One of the two output ends of the SMD dual-color temperature lamp beads connected in series is connected to the D1 pin of the TC3085HB integrated block, and the other end is connected to the D2 pin of the TC3085HB integrated block; the negative output end of the rectifier bridge output end is grounded and divided into 3 outputs, one of which is connected in series with the rectifier capacitor and then connected to the VCC pin of the TC3085HB integrated block, the second is connected in series with the first resistor and then connected to the CS1 pin of the TC3085HB integrated block, and the third is connected in series with the second resistor and then connected to the CS2 pin of the TC3085HB integrated block; the GND end of the TC3085HB integrated block is grounded. Such a structure with appropriate component combination can narrow the width of the soft light strip to the greatest extent to adapt to the placement in a narrow space. According to the current lamp bead optimization, the dual-color temperature lamp beads preferably use 3030 dual-color lamp beads, 2025 dual-color lamp beads, 3535 dual-color lamp beads, 3528 dual-color lamp beads or 2835 dual-color lamp beads. Of course, it is not limited to the above-mentioned models of dual-color lamp beads.
[0007] Furthermore, a single row of 12 SMD dual-color temperature lamp beads are connected in series, and the length of each main line unit is 10cm. The capacitance value of the rectifier capacitor = 4.74μF, the first resistor R1 = 100 ohms, and the third resistor R3 = 1M ohms. Such a structure can narrow the width of the soft light strip to the greatest extent, achieving the effect of 10cm per cut, so as to adapt to the environment with a relatively small space and a slightly lower requirement for luminous flux, and the cost is relatively low.
[0008] Furthermore, a single row of 6 SMD dual-color temperature lamp beads are used in series, and the length of each main line unit is 5 cm. The capacitance value of the rectifier capacitor = 4.74 μF, the first resistor R1 = 430 ohms, and the third resistor R3 = 1M ohms. This is to adapt to the environment with a relatively small space and slightly higher requirements for light flux.
[0009] Furthermore, a double-row lamp bead design is used, with a double-layer structure of 6 SMD dual-color temperature lamp beads in each row. The number of SMD dual-color temperature lamp beads connected in series is 12, arranged in double rows of 6 on the top and 6 on the bottom, and the rows are connected in series. The length of each main line unit is 5 cm. The capacitance value of the rectifier capacitor (C) = 4.74μF, the first resistor R1 = 100 ohms, and the third resistor R3 = 1M ohms. Due to the double-row lamp bead design, the width of the soft light strip is increased, so it is suitable for slightly wider space placement and for use in environments with high requirements for luminous flux.
[0010] When in use, you can cut off the middle of the left or right column of copper foil of a single main circuit unit within a random 20cm range at the end of the long soft light strip as needed and directly connect it to the civil power supply for normal use without affecting the normal use of the front section or the rear section of the cut end.
[0011] The utility model can realize a dual-color temperature LED soft light strip with simpler structure, more reliable control, longer life and lower cost. It can not only solve the problem that the light strip becomes larger in size when it is dual-color, but also can realize short size (less than 20 cm) and be cut and used at will, and solve the problem of poor brightness of the head and tail parts under long distance conditions, and can also realize direct connection to civil mains for use.
