[0018] See also Figure 1-8, a method for preparing an anti-glare light strip, the anti-glare light strip comprising a lamp body 1, the lamp body 1 comprising a lamp body inner core 11 and a lamp body shell 16 arranged outside the lamp body inner core 11, the lamp body inner core 11 comprising a light diffusion layer 13 and light shielding layers 12 arranged on both sides of the light diffusion layer 13, an anti-glare sheet groove 14 is formed between the top of the light diffusion layer 13 and the tops of the two light shielding layers 12, the anti-glare sheet 18 is installed inside the anti-glare sheet groove 14, an LED light board 17 is arranged at the bottom of the lamp body inner core 11, an anti-glare sheet 18 with grid-shaped through holes is arranged at the top of the lamp body inner core 11, and a light-emitting surface layer 15 located at the top of the anti-glare sheet 18 is embedded at the top of the lamp body shell 16, the preparation method comprises the following steps: The extrusion sleeve type is realized by extruding the diffusion glue, light-blocking color glue and transparent glue from each extruder and feeding them into their respective flow channels in the mold to form the light diffusion layer 13, the light-shielding layer 12 and the luminous surface layer 15. The light-shielding layer 12, the luminous surface layer 15 and the light diffusion layer 13 are co-extruded as a whole; A space is reserved between the light-emitting surface layer 15 and the diffusion layer for the anti-glare sheet 18 to pass through, and a lamp board groove 131 is reserved at the bottom of the diffusion layer. The anti-glare sheet 18 is passed through the anti-glare sheet groove 14 to be built into the lamp body 1, and the LED lamp board 17 is passed through the lamp board groove 131. This design method uses a set of LED lamp board 17 and anti-glare sheet 18 to the lamp body 1, which is convenient for later assembly.

[0019] Specifically, the luminous surface layer 15 is located above the anti-glare sheet 18 and completely covers the anti-glare sheet 18. The light of the LED lamp beads 171 penetrates the light diffusion layer 13 and the anti-glare sheet 18 and is transmitted through the luminous surface layer 15. The luminous surface layer 15 presses the anti-glare sheet 18 tightly against the light diffusion layer 13 and is co-extruded with the two sides of the lamp body shell 16 as one. The luminous surface layer 15 is a flat surface and there are no surface holes that cause dust accumulation and affect the luminous effect. It is more convenient to use. The LED lamp board 17 is the light source component of the light strip. It is a flexible circuit board with various package types of LED lamp beads 171 mounted on it, which determines the color temperature and color of the finished product of the light strip.

[0020] Specifically, the top of the shading layer 12 is higher than the top of the light diffusion layer 13, and a light board groove 131 is provided at the bottom of the light diffusion layer 13. The LED light board 17 is arranged inside the light board groove 131, and the LED lamp beads 171 on the top of the LED light board 17 are transmitted through the light diffusion layer 13, which has the effect of evenly distributing light.

[0021] Specifically, the bottom end of the shading layer 12 extends to the bottom of the LED light board 17 to shield the two sides and the bottom of the LED light board 17 from light.

[0022] Specifically, a number of LED lamp beads 171 are provided on the top of the LED lamp board 17. The LED lamp board 17 is a flexible body, the anti-glare sheet 18 is a flexible body, and the light diffusion layer 13 is a transparent or foggy flexible body. The light emitted by the LED lamp beads 171 on the top of the LED lamp board 17 passes through the light diffusion layer 13 and is emitted. The light diffusion layer 13 is made of a transparent or foggy flexible body, and can be made of silica gel material. A number of LED lamp beads 171 are evenly distributed on the top of the LED lamp board 17, and the light distribution is more uniform.

[0023] Specifically, a number of through holes 181 are provided inside the anti-glare sheet 18. A number of the through holes 181 form a grid shape. The anti-glare sheet 18 is a grid-shaped flexible body with a certain thickness. The anti-glare sheet 18 is placed in the anti-glare sheet groove 14 above the light diffusion layer 13. The hollow through holes 181 inside the anti-glare sheet 18 have a light-transmitting function. The light emitted by the LED lamp beads 171 is blocked from scattering to the periphery by the grid-shaped border with a certain thickness, obtaining a lower UGR value and achieving the anti-glare effect. Moreover, the anti-glare sheet 18 is built-in between the light-emitting surface layer 15 and the light diffusion layer 13, and is in a state of being built-in in the lamp body 1, which also solves the shortcomings of the existing anti-glare process of the light strip being prone to fading, falling off, and dust accumulation, which affect the effect.

[0024] Specifically, the anti-glare sheet groove 14 is U-shaped or "mouth" shaped, and the lamp board groove 131 is inverted T-shaped. The U-shaped anti-glare sheet groove 14 is composed of the light diffusion layer 13 and the light-shielding layer 12, and the "mouth" shaped anti-glare sheet groove 14 is composed of the light diffusion layer 13, the light-shielding layer 12, and the light-emitting surface layer 15.

[0025] Specifically, it further includes an end cap one 2 and an end cap two 3. The end cap one 2 and the end cap two 3 are respectively arranged at both ends of the lamp body housing 16. A wire 31 with one end electrically connected to the LED lamp board 17 is provided inside the end cap two 3. The end cap one 2 and the end cap two 3 are used to block both ends of the lamp body housing 16. The wire 31 inside the end cap two 3 is conductively connected to the LED lamp board 17, and the wire 31 is not limited to passing through the inside of the end cap two 3. According to the installation environment, the wire 31 can also pass through the inside of the end cap one 2.

[0026] Specifically, the anti-glare sheet 18 can adopt the technology of continuous die pressing. After forming a certain length of the anti-glare sheet 18, the finished product is controlled by an automatic device to step forward, move out of the mold, and after accurately positioning the tail of the product of this die with the mold positioning slot hole, the tail is connected end to end with the finished product of the next die pressing. In this way, the anti-glare sheet 18 in the form of a long coil is manufactured; it can also adopt the method of die pressing to form a finished anti-glare sheet of a certain length, and then the short anti-glare sheets are adhesively connected end to end with glue or the two are die-pressed end to end again to manufacture the anti-glare sheet 18 in the form of a long coil.

[0027] To sum up, the preparation method of the anti-glare light strip can seal the anti-glare sheet 18 inside the lamp body 1 by adopting a one-time co-extrusion, two-time co-extrusion or extrusion sleeve type processing method, thereby solving the shortcomings of the existing light strip anti-glare process that is easy to fade, fall off, and accumulate dust and affect the effect. The luminous surface layer 15 after processing has good sealing and high surface flatness. There will be no holes on the surface that cause dust accumulation and affect the luminous effect. The anti-glare sheet 18 with grid-like through holes blocks the light emitted by the LED lamp beads 171 from scattering to the surrounding area, thereby obtaining a lower UGR value, achieving an anti-glare effect, and meeting user needs.
