Description

Hose lamp

Technical field to which the present invention pertains

The utility model relates to a decorative lighting device, in particular to an improved structure of a hose lamp body capable of simulating a continuous uniform and vivid soft light effect of a neon lamp.

Prior art prior to the present invention

As a decorative lighting fixture, the existing hose lamp has been widely used in garden art, commercial advertising and garden decoration. Its advantages are: automatic machine extrusion during production, low production cost; It can be extended and cut, impact resistant, safe and reliable, and can be freely made by consumers according to their needs. The decorative effect is wonderful and changeable. At the same time, however, the shortcomings of the existing hose lamps are also obvious, that is, the lighting is uneven, non-continuous, and there is no neon light. The reason is that the light source covered in the hose lamp tube is a point-like illuminant, such as a micro bulb or an LED, which is longitudinally distributed in the tube at intervals, and is emitted by the granular point source. The light can't reach the beauty of the neon lights.

As a decorative lighting fixture, neon light is not only bright and colorful, but also uniform and soft, so it is widely used in facades, signboards, subtitles, dance halls, hotel bars and building exteriors. However, neon lights also have their fatal weaknesses, that is, they consume large amounts of electricity, high voltage, high cost, fragile glass tubes, inconvenient installation and transportation, can not be bent at any time, can not be cut, and require professional technicians for installation and maintenance. Inconvenient to maintain, it is also extremely unsafe. Therefore, people have been searching for a light source that can replace neon lights for many years.

For example, someone used a hose light to simulate a neon light, creating a "plastic neon" (or "soft neon"). Although the hose has a built-in LED as a point source device, it avoids the disadvantages of large power consumption, high voltage, fragile and difficult to install and maintain, and can also be freely bent and can be cut and extended, but due to its LED spacing is large and the thickness of the skin is uniform and thin, and it is made of transparent material. The LED particles are not continuous between the point light sources. The appearance of the light is intermittent granular, discontinuous and uneven, so the hose light does not reach the neon light. Decorative effect. In order to solve the problem of continuous uniformity of light, people added a transparent hard lamp cover to the hose lamp to atomize the light from the LED point light source to achieve uniform, continuous and soft light, but this has undoubtedly increased. Cost, and still can't bend the shape at will, it is inconvenient to cut, and transportation is not convenient.

On this basis, people have invented a simulated neon lamp with an acrylic material as the outer casing. This simulated neon lamp can be bent and shaped when heated. This is a single entrance, and the simulated neon light line is uniform and continuous. The neon light can be achieved. However, since the acrylic material is hard and brittle, the simulated neon lamp cannot be bent at any room temperature, and it is not easy to cut; and it is used for the flexible connecting circuit board as an electrical connecting component and by means of a potting glue. The flexible strip circuit board and the LED make the process cumbersome, difficult to manufacture, and costly; in addition, since the flexible strip circuit board is not extendable, its length is limited and cannot be extended; Not environmentally friendly. Therefore, the decorative lighting market still expects a low power consumption, safe low voltage, simple structure and process, low cost, convenient transportation, installation and maintenance, can be bent freely, and can be easily cut as needed. And light-emitting devices with uniform, continuous and bright light.

The existing hose lamp generally comprises the following parts. Referring to FIG. 12, the elongated transparent plastic inner core 110 is longitudinally provided with at least two conductive wires 120, 130, and the transparent plastic inner core is provided with The space of the longitudinal groove 140 or the plurality of lateral holes 150a, 150b, 150c, 150d, 150e is for accommodating the plurality of bulbs 160a, 160b, 160c, and their connecting wires 170a, 170b. The bulbs are electrically connected to the conductive wires in series, and then a transparent plastic cladding layer 180 is coated on the transparent plastic core. .

In the prior art of the hose lamp industry, the hose lamp is generally divided into two structures according to the arrangement of its light source (such as a light bulb, LED): The inner core of the hose lamp is provided with a space of a longitudinal groove for receiving A plurality of light sources are disposed, and the light source is disposed in the same direction as the longitudinal direction of the tube. The hose lamp is called slotted hose lamp in the industry-Horizontal type; the space of the hose lamp is provided with a lateral hole space. It is used to accommodate multiple light sources. The direction of the light source is perpendicular to the longitudinal direction of the tube. This type of hose lamp is called the perforated hose lamp in the industry - Vertkal type.

However, the patent does not disclose the light source defect of the hose lamp compared with the neon lamp, that is, the light source coated in the hose lamp tube is a point-like illuminator, such as a micro bulb or an LED, which is longitudinally distributed at intervals. In the tube, the light emitted by the granular point source cannot achieve the beauty of continuous light in the neon light.

No. 6,186,645 B1, issued on Feb. 13, 2001, the patent name being a flexible illumination system and mounting method. The patent also discloses that the outer surface of the inner core of the hose lamp or the inner surface of the cladding layer is provided with a longitudinal groove-like texture, that is, an improved structure of the slotted hose lamp, which can diverge the hose light source The emitted light achieves a uniform effect of improving the illumination of the hose light. However, this patent does not claim that the invention can achieve a uniform continuous light effect of the simulated neon light. In fact, the invention cannot fundamentally achieve the uniformity of the simulated neon light. Continuous light effects.

Further, U.S. Patent No. 6,565,251 B2, issued on May 20, 2003, the patent name of a tubular decorative lamp. The patent discloses that the inner core and the cladding of the hose lamp can be arranged in different shapes, such as a circular shape, a square shape, an elliptical shape, a convex shape, a concave shape, a wave shape, and a core layer and a cladding layer are formed between each other. Or a plurality of longitudinal spaces for infusing an insulating liquid to improve the refraction and reflection of the light of the source.

The utility model relates to a modified structure of a hose lamp body, and the first preferred embodiment comprises the following steps: Often 2 copper stranded wires 01a, Olb pass through the extrusion molding machine forming holes (not shown), automatically extruded continuously from flexible opaque plastic, usually flexible white or other color opaque PVC A preformed strip of preformed length, the strip being the core 02 as described in the industry. The copper stranded wire for forming the hole through the extrusion molding machine, that is, the copper stranded wire in the core wire has at least two, and may be three or four.

Then, over the entire longitudinal length of the core wire 02, a plurality of transverse through holes 03a, 03b parallel to the copper strands 01a, Olb are uniformly punched by an automatic punching machine (not shown). 03c, 03d, the transverse hole is disposed in the core wire 02, and the other side opposite to the copper strands 01a, Olb is parallel to the copper strands 01a, Olb. The transverse through holes punched in the core wire have at least one column, and may have two columns, three columns, and the like.

An important feature of the improved structure of the hose lamp body of the present invention as shown in FIG. 1 and FIG. 2 is that the copper strands 01a, 01b are disposed above and below the core wire 02 at intervals. One side of the cross section, the transverse through holes 03a, 03b, 03c, 03d are disposed on the other side of the core wire 02 parallel to the copper strands 01a, 01b, which is advantageous for the softness of the present invention.

LED bulbs have excellent characteristics such as low energy consumption, low heat, high brightness and small volume. They can be used to shorten the spacing of LED bulbs and increase the number of LED bulbs per unit length of hose lamps without causing overheating of hose lamps. It is practical to increase the brightness of the hose light beyond the brightness of the glass neon. The utility model relates to a preferred embodiment of the improved structure of the hose lamp body, wherein the LED bulb has a diameter of 3-5MM, the LED brightness is about 200 Mcd, and the center hole of the transverse hole for accommodating the LED bulb is only 1/2. inch.

After the core wire 02 is formed, the LED bulbs 04a, 04b are individually inserted into the transverse holes 03a, 03c of the core wire 02, and a transverse hole 03b, 03d is left between the LED bulb and the lateral hole into which the LED bulb is inserted. The lead wire 07 of the LED bulb is connected to the lead wire 05 of the bulb, or its current limiting resistor 06, and the lead wire 07 of the leading end of the LED bulb series string and the lead wire of the end (not shown) are twisted with the copper in the above-mentioned core wire 02. Lines 01a, 01b are electrically connected (as shown in Figure 1). After the LED lamp string is filled with the core wire 02 of the predetermined length, the core wire 02 and a prefabricated milky white translucent body, that is, the astigmatism body 08 of the improved structure of the hose lamp body of the present invention, At the same time, through the forming hole 21 of the extrusion molding machine 20, as shown in FIG. 3, the flexible plastic 22 is automatically continuously extruded, usually a flexible transparent PVC, and a core 102 and a diffusing body 08 are formed. a portion of the cladding layer 14 having the same length as the above-mentioned core wire, the portion of the cladding layer 14 above the LED bulb 04, that is, the portion above the astigmatism body 08, the appearance of which is a semicircular curved surface 10, To simulate the neon light glass tubular luminous surface.

When the core wire 02 and the diffuser 08 pass through the extrusion molding machine 20 to form the hole 21, the preformed diffuser 08 must be disposed directly above the LED bulb 04 in the core wire 02, that is, the LED bulb 04 should be placed at Below the astigmatism, it is close to the midline position of the astigmatism. The implementation of the above requirements in the hose light industry is a common prior art and will not be described further herein.

Since the core wire 02 is made of an opaque plastic, after the LED bulb is placed in the transverse hole of the core wire, the light emitted by the LED light bulb cannot penetrate both sides of the core wire 02, so that the opaque core wire It acts as a shading device, blocking the side light emitted by the LED bulb 04, causing the light to be emitted only from the top of the LED bulb 04 and then emitted outward through the diffuser 08.

The astigmatism body 08 of the improved structure of the hose lamp body is a milky white translucent body, or a misty translucent body, usually a flexible milky white PVC or Acrylic extrusion molding; And the height is related to the brightness and illumination angle of the LED bulb in the core. The brightness of the LED bulb is high or the illumination angle is large, and the height and width can be larger; the brightness of the LED bulb is small or the illumination angle is small, and the height and width must be smaller. The larger the width and height of the astigmatism, the more the appearance brightness of the hose lamp of the present invention is lost, and the appearance of the point light source should be eliminated; the smaller the width and height of the astigmatism, the weaker the utility model is. A hose lamp eliminates the appearance of a point light source and has a correspondingly high brightness. The utility model relates to a preferred embodiment of the improved structure of the hose lamp body, wherein the LED bulb has a diameter of 3-5nim, the LED brightness is about 200 Mcd, and the LED illumination angle is 45 ^Q C, which is used for accommodating the lateral direction of the LED bulb. The center of the holes is only 1/2 inch apart. The height dimension H of the diffuser 08 is 14 mm, and the width dimension L of the diffuser 08 is 8 mm, as shown in FIG. The light emitted by the LED bulb is refracted twice by the transparent PVC layer, that is, the cladding layer 14 and diffused and refracted by the astigmatism 08, and the edge regions of the light emitted by the adjacent LED bulbs 04a, 04b, 04c, and 04d are mutually Overlap, such as the edge regions of the light emitted by the LED bulbs 04b, 04c form an overlap region 12, so that the brightness of the LED bulb in the edge region is enhanced, which is approximately equal to the brightness of the light emitted from the center of the LED bulb, as shown in FIG. Therefore, above the illumination of the LED bulb 04 of the hose lamp of the present invention, that is, on the semicircular curved surface 10 of the cladding layer 14, From the appearance, there is a continuous and uniform light effect of neon lights.

After the cladding layer is formed, the copper stranded wires 01a, 01b should be electrically connected to the power supply line 11 of the power supply, and a plastic cover is provided on the electrical connection to protect the electrical connection, that is, to form a joint. 12, as shown in Figure 1. At the same time, at the end of the core wire 02 and the cladding layer 14, a plastic cover for covering the end of the copper stranded wire and the electrical connecting wire thereof is formed, that is, a tail plug 13 is formed, as shown in FIG. Show. Electrical enclosures and plastic enclosures that protect electrical connections have many different implementations in the prior art and will not be described in detail herein.

As shown in FIG. 1, the LED driving component may be an AC-DC current converting component. The DC current supplies power to the LED bulb, which stabilizes the LED bulb and eliminates flicker when the LED bulb emits light. The prior art AC to DC, usually rectified with 4 diodes, or other more precise rectification techniques, will not be described in detail herein. The LED driving component of the utility model can also be an LED pulse current driving component, and the LED light bulb is powered by the pulse current, so that the luminous efficiency of the LED bulb is improved, and the energy consumption is reduced, that is, the same heat consumption in energy consumption. At the same time, LED bulbs can have higher illumination levels, which can further improve the illumination intensity of analog neon lights.

The utility model relates to a modified structure of a hose lamp body. The second preferred embodiment is as follows: as shown in FIG. 5, FIG. 6, FIG. 7, after the LED lamp string is filled with the core wire 02 of the predetermined length It is not necessary to separately prepare the astigmatism in advance, but when the core wire 02 passes through the molding hole 17 of the extrusion molding machine 16, the astigmatism body, that is, the cream translucent body and the coating layer are simultaneously The length is automatically and continuously integrated and extruded, a scatterer 09 is formed above the core 02, a cladding layer 141 is formed under the core 02 and on both sides, and the astigmatism 09 and the cladding 141 are integrally extruded at the same length. The two are a whole. The plastic 19 used to form the diffuser 09 and the cover layer 141 is a flexible cream translucent plastic, usually a flexible milky white translucent PVC material. The astigmatism 'body 09 above the core line 02 has a height dimension H of 14 mm and a width L of 8 mm.

The utility model relates to a modified structure of a hose lamp body. In a second preferred embodiment, the light emitted by the LED bulb is diffused and refracted by the astigmatism body 09, and the adjacent LED bulbs 04a, 04b The edge regions of the light emitted by 04c, 04d overlap each other. For example, the edge regions of the light emitted by the LED bulbs 04b, 04c form an overlap region 121, so that the brightness of the LED bulb in the edge region is enhanced, and is approximately equal to the center portion of the LED bulb. The brightness of the light emitted, as shown in Figure 8.

The structure of the second preferred embodiment described above may be constructed in another manner, that is, it may be The astigmatism, when continuously and integrally extruded at the same length as the cladding layer 141, a longitudinal through hole 091 is disposed in the astigmatism above the core 02 to save material, thus forming the astigmatism 090, such as Figure 9 and Figure 10. The astigmatism body 090 and the cladding layer 141 are integrally extruded at the same length, and the two are integrated. At this time, since the air in the longitudinal through hole 091 has the ability to refract and diverge light, it is inferior to the opaque body of the milky white translucent PVC material. Therefore, in order to achieve the same continuous light-emitting effect of the neon light, as shown in FIG. 9 and FIG. The height dimension HI and the width dimension L1 of the diffuser 090 above the core line 02 should be larger than the astigmatism 09 above the core line 02 as described in the second preferred embodiment of FIG. 5 and FIG. The height H and the width L are different depending on the size of the longitudinal through hole 091. The height dimension HI and the width dimension L1 of the diffuser 090 are also different, and the specific dimensions will not be described in detail herein.
