Description

Decorative lamp belt with patterns on surface and manufacturing method thereof

Technical Field

The invention relates to the field of lamp belts, in particular to a decorative lamp belt with patterns on the surface and a manufacturing method thereof.

Background

The LED lamps made by the prior art have three major categories:

the first type: the lamp strip is generally installed indoors and used in a hidden groove, and the lamp strip cannot be directly attached to a place where the lamp strip can be seen indoors.

The second type: the LED bare lamp strip is formed with transparent resin for use, the lamp strip only solves the waterproof problem, but can still clearly see the circuit board and the LEDs, the appearance is still not attractive, and light emitted by a small LED light source is transmitted out of the transparent adhesive tape and is still very glaring, so that the lamp strip is also arranged in an indoor hidden groove for use, and the lamp strip cannot be clearly arranged and used in a place where the lamp strip can be seen indoors.

In the third category: after a diffusant is added into a light-transmitting resin, the resin with the diffusant is heated and extruded on an extruder to be wrapped on a bare lamp strip, the LED and a circuit board cannot be seen from the lamp strip, the appearance problem is solved, light emitted by the LED is emitted outwards after being diffused by the diffusant, and soft light is emitted, so that the problem of directly emitting dazzling light is also solved, but the lamp strip is heavy in outer coating adhesive weight, high in cost, large in size and thick, needs to be grooved and installed when being installed indoors for surface mounting, is complex to install, or is clamped and clamped by a clamp, is unsightly, cannot be simply installed by double-faced adhesive tape in a sticking mode, is too thick and too heavy, is not firm in double-faced adhesive, is adhered on the diffusion resin of the outer coating, is made of organic silicon resin or flexible PVC resin in the diffusion resin industry, the surface adhesiveness of the double-faced adhesive and the diffusion resin is poor in adhesion, and can be used as a surface mounting lamp strip, but only can be arranged in the groove by grooving, and the front surface of the lamp strip is exposed. The installation may damage walls or homes.

Therefore, by comprehensively summarizing the three types of lamp belts, the inventor finds that the existing LED lamp belts are not suitable for indoor surface mounting, what is called surface mounting, namely the lamp belts are exposed and visible after mounting, but the surface mounting is divided into two types, namely, the surface mounting needs to be grooved for mounting, a wall body or furniture is damaged, the surface mounting is carried out again, the surface mounting lamp belts can be generally used only when a house is decorated, and the other type is that users can simply mount the surface mounting lamp belts by themselves and directly and simply stick the surface mounting lamp belts on the wall or the furniture without mounting when the house is decorated and can simply mount the surface mounting lamp belts indoors such as home at any time.

The surface mounted light strip which is simply mounted must satisfy the following conditions:

first, the light strip must have a beautiful appearance when not lit.

Secondly, the lamp strip must have beautiful appearance when being lightened and must emit soft light without dazzling.

And thirdly, safety is required, and the LED lamp strip is safer by using a safe low-voltage LED lamp strip which is not more than 36V.

And fourthly, the installation is simple, so that the double-sided adhesive tape is required to be suitable for being firmly adhered and installed without falling off.

Modern indoor lighting develops towards the direction of invisible light, namely, light can be seen but a light source cannot be seen, and product research and development design needs to meet the requirement of invisible light as much as possible.

Sixth, the development direction of modern indoor lighting is the development direction without main lamps, that is, lighting cannot be solved by one bright lamp in one room, one room is solved by a plurality of lamps, each lamp does not need to be bright, especially, indoor surface-mounted lamp strips are auxiliary lamps of decorative lines, and cannot be too bright and too dazzling! Is too glaring and bright, but is polluted by light! Therefore, the brightness of the surface-mounted lamp strip needs to be reduced, and meanwhile, the attractiveness is improved.

In order to overcome the defects and shortcomings, the invention produces the surface-mounted lamp strip which has beautiful appearance, is lightened without dazzling and is convenient to install, and the invention adopts the following method to manufacture the decorative lamp strip with patterns on the surface, thereby overcoming the new technology and reducing the cost, and the specific method comprises the following steps:

the method comprises the steps of welding LEDs or LEDs and control elements by using a connected flexible circuit board containing a plurality of lamp strip circuit boards to form a connected LED bare lamp strip, then pasting the connected LED bare lamp strip on a horizontal platform, applying light-transmitting glue on one surface on which the LEDs are welded, covering the circuit board and the LEDs with the light-transmitting glue, heating to solidify the light-transmitting glue or placing the light-transmitting glue at normal temperature to solidify the light-transmitting glue, printing characters or/and patterns on the surface of the light-transmitting glue, and cutting the light-transmitting glue into a plurality of single decorative lamp strips with patterns by using a slitting machine.

Or after the LED or the LED and the control element are welded by the conjoined flexible circuit board containing a plurality of lamp strip circuit boards, manufacturing a connected LED bare lamp strip, cutting the connected LED bare lamp strip into a plurality of single LED bare lamp strips by a slitting machine, adhering the bare lamp strips on a strip-shaped aluminum material, applying transparent adhesive on the surface for welding the LED, covering the circuit board and the LED with the transparent adhesive, heating to cure the transparent adhesive or standing at normal temperature to cure the transparent adhesive, printing ink on the surface of the light-transmitting adhesive to form patterns, printing the patterns on the whole lamp strip, and curing the ink patterns to form the decorative lamp strip with the patterns, wherein the patterns on the lamp strip enable the lamp strip to be a more beautiful lamp strip, meanwhile, the printing ink patterns have the function of shielding light, the light emitted by the LED is partially shielded by the printing ink patterns, dazzling strong light is eliminated or reduced, and the light emitted by the lamp strip is changed into relatively soft light compared with the lamp strip without the printing ink patterns.

The flexible lamp strip manufactured by the method really realizes the following steps:

firstly, when the lamp strip is not lightened, a beautiful figure is formed, and the appearance is artistic.

Secondly, when the lamp strip is lightened, beautiful lines are displayed, the lines are artistic, and meanwhile, the lamp strip is free of dazzling light and becomes soft in light.

Thirdly, the low-voltage lamp strip below 36V is mainly designed and manufactured.

And fourthly, the double-sided adhesive tape is mainly designed to be used for pasting and installation, and the wall and the groove do not need to be punched during installation, so that the installation is simple.

And fifthly, the LED light source is shielded by the ink, so that invisible light source or fuzzy and unclear light source is realized.

The lamp strip is an auxiliary lighting product, and the lamp strip meets the requirement of surface-mounted auxiliary lighting, namely, the brightness cannot be too high, the lamp strip cannot be dazzled, and the appearance is attractive.
