The present disclosure relates to a technical field of light strips, and in particular to a manufacturing method of an anti-glare light strip.
Currently, neon light strips are widely used in the market, and most neon light strips are design without considering professional optical performance. However, more and more users pay more attention to comfort of lighting, so it is necessary to design the neon light strips while fully considering the optical performance thereof.
In the prior art, conventional neon light strips generally use ink to screen print a layer of honeycomb coating on a surface thereof or use gel to bond honeycomb anti-glare plates on the surface thereof. A bonding process thereof is complicated and requires manual bonding. In addition, the honeycomb anti-glare plates are only bonded to two sides of a conventional light strip, a bonding area thereof is not large, and a bonding effect is not firm, leading to poor integrity of the conventional light strip. In addition, holes on the honeycomb anti-glare plates may accumulate dust, and the dust is not easy to clean and may block a reflective surface of the conventional light strip. A process of using ink to screen print the layer of honeycomb coating is to screen print a grid on a light body of the conventional light strip. Since the honeycomb coating has no three-dimensional effect and only has an appearance effect, which has no substantial help in reducing unified glare rating (UGR) and is unable to realize an anti-glare effect, resulting in an unsatisfactory effect.
To achieve the above object, the present disclosure provides an manufacturing method of an anti-glare light strip. The anti-glare light strip is manufactured by only one co-extrusion process. The manufacturing method comprising step:
Alternatively, the anti-glare light strip is manufactured by two times of co-extrusion processes. The manufacturing method comprising step:
The anti-glare sheet is accommodated in the mounting groove defined in the top portion of the inner core. Before wrapping the anti-glare sheet and the inner core with the first gel, the anti-glare sheet is aligned with the inner core at an entrance of the second extruder mold and is placed into the second extruder mold together with the inner core for being wrapped by the first gel. Alternatively, before wrapping the anti-glare sheet and the inner core with the first gel, the anti-glare sheet is fixed in the mounting groove of the inner core by a second gel, and the anti-glare sheet, the inner core, and the second gel are placed into the second extruder mold together for being wrapped by the first gel.
Alternatively, the anti-glare light strips can also be manufactured through the co-extrusion process and a sleeve process. The manufacturing method comprising steps:
Compared with the prior art, in the present disclosure, one co-extrusion process, two times of co-extrusion processes, or the co-extrusion process and the sleeve process are adopted to manufacture the anti-glare light strip. The anti-glare sheet is sealed inside the light body, which solves a problem that an anti-glare sheet of a light strip manufactured by a conventional anti-glare process is easy to fade, fall off, accumulate dust, and affect an anti-glare effect. After processing, the light-transmitting layer has good sealing and high surface flatness. There is no holes on the surface and no dust accumulation, thus avoiding affecting a luminous effect. The anti-glare sheet with the grid-shaped through holes blocks light emitted by LED lamp beads from scattering to surroundings, thereby obtaining a lower UGR value, achieving the anti-glare effect, and meeting user needs.

Technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.
As shown in
The anti-glare sheet 18 is disposed between the light diffusion layer 13 and the light-transmitting layer 15.
The anti-glare light strip is manufactured by only one co-extrusion process. Specifically, the diffusion gel, light blocking color gel, and transparent gel are silica gel. After the anti-glare sheet 18 and the LED light board 17 are put into the extruder mold together, the extruder respectively extrude the diffusion gel, the light blocking color gel, and the transparent gel into the extruder mold at the same time. After the diffusion gel, the light blocking color gel, and the transparent gel are solidified, the anti-glare light strip is formed in the extruder mold at one time. That is, the anti-glare light strip is manufactured by a one-time co-extrusion process.
As shown in
The light body shells 16 are integrated with the light shielding layers, the light body shell 16 two side walls and a bottom portion of the inner core 11, so that the anti-glare sheet 18, the inner core 11, and the light body shells 16 form an integrated structure.
The anti-glare sheet 18 is accommodated in the mounting groove 14 defined in the top portion of the inner core 11,
Before wrapping the anti-glare sheet 18 and the inner core 11 with the first gel, the anti-glare sheet 18 is aligned with the inner core 11 at an entrance of the second extruder mold and is placed into the second extruder mold together with the inner core 11 for being wrapped by the first gel. Alternatively, before wrapping the anti-glare sheet 18 and the inner core 11 with the first gel, the anti-glare sheet 18 is fixed in the mounting groove of the inner core 11 by a second gel, and the anti-glare sheet 18, the inner core 11, and the second gel are placed into the second extruder mold together for being wrapped by the first gel.
In the embodiment, the first gel and the second gel are the silica gel. The anti-glare light strip is manufactured by two times of the co-extrusion processes. In a first co-extrusion process, the LED light board and different silica gels are fed into the first extruder mold together to form the inner core defining the mounting groove on the top portion thereof. In a second co-extrusion process, the inner core and the anti-glare sheet are simultaneously fed into the second extruder mold, and the the inner core and the anti-glare sheet are wrapped with the silica gel. After the silica gel is solidified, the anti-glare light strip is obtained in the second extruder mold. It should be noted that in the embodiment, the first extruder mold is different from the extruder mold. Of course, in other embodiments, only one extruder mold may be used to form the inner core and the anti-glare light strip in batches.
As shown in
By such design, the LED light board 17 and the anti-glare sheet 18 are sleeved in the light body 1 to facilitate later assembly.
The anti-glare light strip of the embodiment is manufactured by one co-extrusion process and a sleeve process. In the co-extrusion process, only the anti-glare sheet is placed into the extruder mold, and different silica gels are fed into the extruder mold through respective extruders. Different silica gels wrap the anti-glare sheet and are solidified, so as to mold a silicone light body without the LED light board in the extruder mold. The silicone light body defines the light board groove. In the sleeve process, the LED light board is inserted into the silicone lamp body to enable the LED light board being sleeved in the silicone light body. Thus, the anti-glare light strip is manufactured.
Specifically, the light-transmitting layer 15 is disposed above the anti-glare sheet 18 and completely covers the anti-glare sheet 18. Light emitted by the LED lamp beads 171 penetrates the light diffusion layer 13 and the anti-glare sheet 18 and is transmitted through the light-transmitting layer 15. The light-transmitting layer 15 presses the anti-glare sheet 18 tightly against the light diffusion layer 13 and is co-extruded with two sides of the light body shells 16 as a whole. The light-transmitting layer 15 is flat without holes that cause dust accumulation, so a light-emitting effect is not affected and the anti-glare light strip is more convenient to use. The LED light board 17 is a light source component of the anti-glare light strip. The LED light board 17 is a flexible circuit board with various package types of the LED lamp beads 171 mounted thereon, which determines a color temperature and a color of the light emitted by the anti-glare light strip.
Specifically, the top ends of the light shielding layers 12 are higher than a top portion of the light diffusion layer 13, a light board groove 131 is defined in the bottom portion of the light diffusion layer 13, and the LED light board 17 is arranged in the light board groove 131. The light emitted by the LED lamp beads 171 on a top portion of the LED light board 17 is transmitted through the light diffusion layer 13, which has an effect of light uniformity and diffusion.
Specifically, the bottom end of each of the light shielding layer extends to a bottom portion of the LED light board 17 to shield light emit from two sides and the bottom portion of the LED light board 17.
Specifically, LED lamp beads 171 are arranged on the top portion of the LED light board 17. The LED light board 17 is flexible, the anti-glare sheet 18 is flexible, the light diffusion layer 13 is a transparent flexible body or a foggy flexible body, and the light emitted by the LED lamp beads 171 on the top portion of the LED light board 17 passes through the light diffusion layer 13. The light diffusion layer 13 is the transparent flexible body or the foggy flexible body, and the light diffusion layer 13 may be made of silicone. The LED lamp beads 171 are evenly spaced on the top portion of the LED light board 17, making a light distribution more uniform.
Specifically, the anti-glare sheet 18 comprises the grid-shaped through holes 181, that is, the grid-shaped through holes form a grid. The anti-glare sheet 18 is a grid sheet-like flexible body with a certain thickness. The anti-glare sheet 18 is placed in the mounting groove 14 disposed above the light diffusion layer 13. The grid-shaped through holes 181 of the anti-glare sheet 18 have a light-transmitting effect. The light emitted by the LED lamp beads 171 is blocked by a grid frame of the anti-glare sheet 18 that has a certain thickness, so the light is not scattered to a surrounding area, thereby obtaining a lower UGR value and achieving the anti-glare effect. The anti-glare sheet 18 is located between the light-transmitting layer 15 and the light diffusion layer 13, and the anti-glare sheet 18 is built in the light body 1, which also solves defects of a conventional anti-glare process of light strips that are easy to fade, fall off, accumulate dust, and affect the anti-glare effect.
Specifically, the mounting groove is U-shaped or square-shaped. The light board groove is inverted T-shaped.
The mounting groove 14 that is U-shaped is defined by the light diffusion layer 13 and the light shielding layers 12, and the mounting groove 14 that is square-shaped is defined by the light diffusion layer 13, the light shielding layers 12 and the light-transmitting layer 15.
Specifically, the anti-glare light strip further comprises a first end cover 2 and a second end cover 3. The first end cover 2 and the second end cover 3 are respectively arranged at two ends of the light body shells 16. A wire 31 is built in the second end cover 3. One end of the wire 31 is electrically connected to the LED light board.
The first end cover 2 and the second end cover 3 are configured to seal two ends of the light body shells 16. The wire 31 passes through an interior of the second end cover 3 and is electrically connected to the LED light board 17. The wire 31 is not limited to passing through the interior of the second end cover 3. According to a mounting environment, the wire 31 may pass through an interior of the first end cover 2.
Specifically, the anti-glare sheet 18 is formed by continuous compression molding technology. After a certain length of the anti-glare sheet 18 is formed, the anti-glare sheet 18 is controlled by an automatic device to step forward to be moved out of a mold. After a tail end of the anti-glare sheet 18 is accurately positioned with a positioning groove of the mold, the tail end of the anti-glare sheet 18 is connected to a head of a next anti-glare sheet 18 and the process is repeated to form a roll of the anti-glare sheets 18. Alternatively, after a plurality of anti-glare sheets 18 are molded, the plurality of anti-glare sheets 18 are geld end to end to form the roll of the anti-glare sheets 18. Alternatively, after the plurality of anti-glare sheets 18 are molded, each two adjacent anti-glare sheets 18 are molded together to form the roll of the anti-glare sheets 18.
In summary, in the present disclosure, one co-extrusion process, two times of co-extrusion processes, or the co-extrusion process and the sleeve process are adopted to manufacture the anti-glare light strip. The anti-glare sheet 18 is sealed inside the light body 1, which solves a problem that an anti-glare sheet of a light strip manufactured by a conventional anti-glare process is easy to fade, fall off, accumulate dust, and affect an anti-glare effect. After processing, the light-transmitting layer has good sealing and high surface flatness. There is no holes on the surface and no dust accumulation, thus avoiding affecting a luminous effect. The anti-glare sheet with the grid-shaped through holes blocks light emitted by LED lamp beads from scattering to surroundings, thereby obtaining a lower UGR value, achieving the anti-glare effect, and meeting user needs.
