Description

Technical Field

[0001] The utility model relates to an LED light strip. Background Art

[0002] LED light strips are LED lamp beads assembled on a strip-shaped circuit board. Currently, LED light strips are widely used as light sources for various strip lamps, such as wall washers. Some wall washers need to be used in situations where multiple colors and white lighting switches are required. Therefore, a light strip 100 with 200 evenly spaced RGBW lamp beads is selected as the light source. Figure 1 As shown in the figure, RGBW lamp beads integrate red (R) chips, green (G) chips, blue (B) chips, and white (W) chips. For example, Chinese utility model patent CN209249458U discloses an RGBW lamp bead with heat dissipation, which can emit both colored light and white light.

[0003] However, in RGBW lamp beads, the volume of white light (W) chips accounts for a small proportion, and the power of white light is limited. Therefore, the number of lamp beads and the arrangement density need to be increased to ensure the lighting effect; and the high unit price of RGBW lamp beads significantly increases the cost of such lamps. Utility Model Content

[0004] The purpose of the utility model is to provide an LED light strip, comprising a strip-shaped circuit board, on which are mounted a plurality of lamp bead groups evenly spaced along an extension direction of the circuit board; each lamp bead group comprises three LED lamp beads spaced apart, and the three LED lamp beads in each lamp bead group are RGB lamp beads, white lamp beads, and RGB lamp beads in sequence; the RGB lamp beads in each lamp bead group are evenly spaced apart; and the white lamp beads in each lamp bead group are evenly spaced apart.

[0005] The LED strips of this technical solution utilize a rationally arranged layout of evenly spaced RGB and white LEDs, selectively emitting uniform colored or white light. The independent placement of the white LEDs increases the power of the white light compared to RGBW LEDs, allowing a smaller number of white LEDs to achieve the white light effect of multiple RGBW LEDs. This solution uses half the number of white LEDs as the RGB LEDs. While reducing the overall number of LEDs, it still meets the requirements for both colored and white lighting, reducing the cost of the LED strips that offer both a single and a dual lighting effect.

[0011] The present application is further described below with reference to the accompanying drawings:

[0012] See attached Figure 2-5 An LED light strip includes a strip-shaped circuit board 1, on which are mounted a plurality of lamp bead groups 2 evenly spaced along the extension direction of the circuit board 1; each lamp bead group 2 includes three evenly spaced LED lamp beads, and the three LED lamp beads of each lamp bead group 2 are RGB lamp beads 21, white lamp beads 22, and RGB lamp beads 21 in sequence; the RGB lamp beads 21 of each lamp bead group 2 are evenly spaced; and the white lamp beads 22 of each lamp bead group 2 are evenly spaced.

[0013] In this embodiment, the circuit board 1 is a flexible circuit board 1 .

[0014] The LED lamp beads are concentrated LED lamp beads with lenses, such as the new type of concentrated lamp beads disclosed in Chinese utility model patent CN219264062U. The high-light-efficiency lamp beads can meet high-power lighting needs and reduce the number of lamp beads.

[0015] The circuit board 1 is provided with a plurality of parallel control circuits; a plurality of lamp bead groups 2 are electrically connected to a control circuit.

[0016] The circuit board 1 is provided with a first soldering pad 11 for electrically connecting the RGB lamp beads 21 and a second soldering pad 12 for electrically connecting the white lamp beads 22; the first soldering pad 11 and the second soldering pad 12 are electrically connected to the control circuit.

[0017] The RGB lamp beads 21 each include a red light (R) chip, a green light (G) chip, and a blue light (B) chip; the first solder pad 11 includes a first positive and negative pin, a second positive and negative pin, and a third positive and negative pin, which are electrically connected to the red light (R) chip, the green light (G) chip, and the blue light (B) chip, respectively.

[0018] The second soldering pad 12 includes a fourth positive and negative pin electrically connected to the white lamp bead 22 .

[0019] In this embodiment, the length of the circuit board 1 is 500 mm-505 mm, that is, about 0.5 meters; in this embodiment, the length of the light strip is 503 mm, which is suitable for the minimum specification unit of commercially available general-purpose wall washer lamps.

[0020] Nine lamp bead groups 2 are installed on the circuit board 1; in order of arrangement, every three lamp bead groups 2 (ie, nine LED lamp beads) are electrically connected to a control circuit.

[0021] The cross-sectional dimensions of the LED lamp bead are 6mm*6mm; specifically, the LED lamp bead described in this embodiment is in a cubic shape, and its dimensions are 6mm*6mm*6mm.

[0022] In each lamp bead group 2 , the distance L1 between the RGB lamp bead 21 and the white lamp bead 22 is 8 mm; the distance L2 between two adjacent RGB lamp beads 21 is 22 mm; and the distance L3 between two adjacent white lamp beads 22 is 50 mm.

[0023] The LED lamp beads of the LED light strip of this technical solution are arranged in a reasonable layout, including RGB lamp beads and white lamp beads distributed evenly at intervals, which can selectively emit uniform colored light or white light, such as Figure 4 and Figure 5 As shown in the figure, the independent placement of white lamp beads can increase the power of white light compared to RGBW lamp beads. A small number of white lamp beads can achieve the white light lighting effect of multiple RGBW lamp beads. The number of white lamp beads in this technical solution is half that of RGB lamp beads. While the overall number of LED lamp beads is reduced, it still meets the needs of color and white lighting, reducing the cost of LED light strips that achieve a two-in-one lighting effect. The LED light strips of this technical solution can be used in lamps such as wall washers that require color and white lighting.

[0024] The above preferred embodiments should be regarded as examples of the implementation methods of the present application scheme. Any technical deductions, replacements, improvements, etc. that are identical or similar to the present application scheme or made based on it should be regarded as within the scope of protection of this patent.
