Improved color-changing flexible neon tube lamp

Abstract

The invention discloses an improved discoloration flexible neon tube lamp, comprising a flexible lamp core wire, a connecting lead in the core wire, a lamp hole, an illuminant and an astigmatism layer. The flexible lamp core wire is provided with a through hole along the longitudinal direction used for arranging the connecting lead; the through hole is arranged at the bottom of the flexible lamp core wire; the illuminant comprises at least two LEDs; furthermore, all pins with the same conductive polarity of the LEDs are arranged at the same side; the end of each LED pin is connected with the connecting lead; the LED colloid and the periphery of the pin are provided with a plastic covering layer so as to form an illuminant unit; wherein, the LED in each illuminant unit are an LED with different luminescence colour; furthermore, the LED in the previous illuminant unit is connected in series with the LED in the subsequent illuminant unit; the LEDs which are connected forwards and backwards are the LEDs with the same luminescence colour. The improved discoloration flexible neon tube lamp has the advantages of good waterproof effect, low cost and uniform luminescence light beam.

Description

Technical field [0001] The invention relates to a lighting device, in particular to an improved color-changing flexible neon tube lamp. Background technique [0002] At present, LEDs are widely used in lighting, so LED applications are particularly important in daily life, especially because multiple LEDs need to be combined to achieve color mixing effects in various flexible strip decorative lights. At the same time, it also has the advantages of long service life, because the existing glass neon lamps have defects such as high voltage danger, fragility, no discoloration effect and power consumption in the same neon lamp tube. [0003] For this reason, some inventors have invented a patent number: 200520057683.0 titled "an improved color-changing hose lamp structure". The middle part of the cross-section of the strip-shaped body of the core wire is horizontally provided with two longitudinal through holes, and the upper side wall of the longitudinal through hole is cut lon...

AI Technical Summary

Problems solved by technology

[0004] 1. Because there is a big obstacle in plugging the LED from top to bottom, it is easy to break the connecting wire when plugging the LED

[0005] 2. In addition, there is another problem that when the product is repaired when some LEDs are not bright, it is usually to cut the coating layer from the bottom of the product with a knife to replace the LED in the core strip shape, but when placing the connecting wire through the The hole is set in the middle of the cross-section of the strip, and the upper side wall of the through hole is cut longitudinally to form a slit. Therefore, in this structure, the LED and the connecting wire can only cut the coating layer and the astigmatism from the top of the product, which is very difficult. , and after the product is repaired, it is easy to leave scars on the luminous surface of the product, which affects the appearance

[0006] 3. Since this invention uses LEDs of three colors R, G, and B to be welded on the PCB board to form a lamp body unit, and then each lamp body unit is connected through wires, but the LEDs in this invention are arranged in a square shape. On the PCB board, because the hose light product is flexible, it needs to be bent frequently during use. During the bending and extrusion process, the LEDs in the same unit will be misaligned, resulting in the breakage of the LED lamp legs, and due to The product needs to be cooled by water during the production process, so it is inevitable that water or water vapor will enter the lamp body, so there is a defect that it is not waterproof, resulting in a short service life

[0007] A patent number also invented by the aforementioned inventor is: 200520058058.8 titled "An Improved Color-changing Hose Lamp Structure". This invention discloses a LED with three colors of R, G, and B placed in a box Thereby a lamp body unit is formed, and then each lamp body unit is connected by wires, but because the LED in this invention is arranged in a box, although this structure solves the defect that the LED pins that exist in the above invention are easy to break, but Since the LEDs must be packed into the box one by one, the manufacturing process is very time-consuming, and the box needs to be made in advance. Also, because the product needs to be cooled by water during the production process, it is inevitable that water or water vapor will enter the lamp body, but this The box is not waterproof, so there are defects of not being waterproof, and defects of high cost

[0008] In addition, a patent number invented by an inventor is: 98234816.9 titled "A New Type of Christmas Light". This invention discloses a connection between the outer layer of the lower part of the light-emitting diode and the wire and the light bulb or light-emitting diode covered by the injection molding layer. The luminous body disclosed in this invention is used for Christmas light strings, and its purpose is to be waterproof, but once it is used for a long time or used outdoors for a period of time, the lower part of the light-emitting diode is easy to separate from the plastic injection layer to form cracks, thereby causing Less than complete waterproof effect, there is a defect of short service life

[0009] In order to solve the waterproof problem of Christmas light strings, there is a patent number: 00242804.0 titled "A Waterproof Decorative Light". A section of the wire of the shell, but this invention is not suitable for some existing flexible light sources with lights due to its large size except for its high cost

[0010] There is also a patent application number: 200610035281.X titled "A Method for Making a Lamp Cap". This invention discloses a method of injecting a plastic layer on the periphery of a single LED and the part connected to the lead wire LED pin, but this method only discloses a A method for manufacturing a single LED illuminant, although this invention is only a simplification of the previous background technology, it discloses a method for manufacturing a single LED illuminant, although this invention is only a simplification of the previous background technology, although it has a certain waterproof effect, but if it is used outdoors for a long time, its wires are easy to separate from the injection plastic layer, so it is easy to enter water, and it cannot achieve the purpose of color mixing in the same unit illuminant, and it is not suitable for some flexible belts that need to change color lamp light source
