Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to fig. 1 to 5 in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the present invention, it should be noted that, if the terms "upper", "lower", "inner", "outer", etc. indicate orientations or positional relationships based on orientations or positional relationships shown in the drawings or orientations or positional relationships conventionally placed when the products of the present invention are used, the description is merely for convenience of description and simplification, but the terms do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

Furthermore, the appearances of the terms "first," "second," and the like, if any, are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.

In another embodiment, the present invention provides a moldable LED lamp comprising:

a hollow, flexible, moldable, and circumferentially light transmissive tube;

an LED string of lights passing through the tube;

the LED lamp string comprises at least two adjacent LED modules which are spaced at a certain distance;

wherein,

the certain distance is greater than or equal to 1 mm;

light rays emitted by the LED lamp string are subjected to diffuse reflection or regular transmission or diffuse transmission in the tube;

one end of the LED lamp string penetrates through one end of the tube, and the other end of the LED lamp string penetrates out of the other end of the tube.

Referring to fig. 1, the upper left area shows the projection onto the background when the LED lamp is emitting light, and the middle and lower right areas show the LED lamp emitting light. Because the tube is hollow, the LED string of lights can penetrate into the tube, and because the tube is flexible and moldable and circumferentially light transmissive, the LED lights can leave a projection on the background, and in fact, because they are circumferentially light transmissive, they can leave multiple projections at certain angles to the background. Fig. 1 illustrates a cloud-like LED lamp.

Because of the different properties of transparent materials and frosted, opalescent materials, the reaction that occurs when light passes through these materials is also different. When light passes through the transparent material, the light is regularly transmitted. When light passes through the milky white and frosted material, the light can be diffused and transmitted. When parallel light is deflected at an angle in the propagation direction in a material with a smooth surface and uniform internal texture, the deflection is called regular transmission of the material and is also called straight transmission. Simply put, you can see the image directly behind the material through it. When the light rays of the collimated light source pass through a transmission material with a rough surface (such as frosted glass, semitransparent glass and opal glass), the transmitted light is diffused, and no regular transmission exists in a macroscopic view, which is called diffuse transmission. When light is transmitted through a diffuse transmitting material, the image we see from behind the material is blurred.

In another embodiment of the present invention, the substrate is,

the distance is 5 mm.

For the present invention, it is possible to vary the density and number of LED modules in the entire tube by adjusting the adjacent LED modules, in particular when the tube is diffusely reflective and the distance is small, the LED lamp can be realized as a well-seen everywhere luminous and circumferentially luminous pattern with a certain shaping.

In another embodiment of the present invention, the substrate is,

the LED lamp dispenses with a metal frame.

It will be appreciated that the LED lamp can be made without a metal frame as compared to the prior art when the tube itself can be shaped. In addition, the tube of the LED lamp serves as the outermost structure, and there is no need for any bottom plate to support the LED lamp.

In another embodiment of the present invention, the substrate is,

the pipe is an acrylic pipe.

It will be appreciated that other hollow, flexible, moldable, circumferentially light transmitting tubes may be alternatively used. Taking an acrylic pipe as an example, the acrylic pipe can be obtained by casting, extruding and injection molding the melted acrylic. The LED lamp can be molded in various manners by using the tube and various molds with low cost.

In another embodiment of the present invention, the substrate is,

the tube is a transparent tube.

More preferably, it is a mixture of more preferably,

the tube is a translucent tube, wherein the translucent tube comprises a fog-like translucent tube.

For transparency or translucency, what is defined is the light transmission of the tube. It will be appreciated that the light transmittance may be selected based on the decorative effect of the light emission. However, it is emphasized that the LED lamp of the present invention is more visually attractive because a metal frame can be eliminated. For example, for a hazy, translucent pipe, there is little to no glare and there is no shielding from the metal frame.

In another embodiment of the present invention, the substrate is,

the LED lamp string emits light in 360-degree circumferential direction through the tube.

In another embodiment of the present invention, the substrate is,

the LED lamp string is a copper wire lamp or an enameled wire lamp.

It should be noted that, when the thinner the wire used by the LED light string is, and the smaller the distance between the adjacent LED modules is, the shorter the distance between the LED light modules of the LED light itself is, the easier the effect of the illuminant with an almost perfect artistic shape, which is almost invisible to the naked eye, almost without obstruction, is achieved.

In another embodiment of the present invention, the substrate is,

the soft insulating layer of the wire of the LED lamp string is a rubber layer or a PVC layer.

It can be understood that the waterproof and anti-aging properties of the rubber layer make the module of the LED light string applicable to more severe outdoor environments. The PVC layer can also be used as a selection type of the soft insulating layer.

In another embodiment of the present invention, the substrate is,

the tube is softened by heating and solidified by cooling.

For this embodiment, the string of lights may be first threaded into the tube, then placed into an oven with the tube to be heated, and after removal from the oven, the current form of the LED light cured along with the tube being molded. More importantly, the LED lamp can be easily changed on the production side or the user side. This is not available in the prior art metal frame LED lamps. Obviously, the material of choice for the tube should be one that is soluble and moldable by changing the temperature.

In another embodiment of the present invention, the substrate is,

the tube and the LED string lights therein may be shaped in sections to different configurations.

Therefore, through one LED lamp which is long enough, the LED light-emitting effect of various different models can be obtained, which is a technical effect that metal frames of different models and LED lamps in the metal frames do not have.

In another embodiment of the present invention, the substrate is,

the tube and the LED string are subjected to a heating temperature of 120 degrees.

It can be appreciated that this is an exemplary heating temperature.

In a further embodiment of the method according to the utility model,

when the connected power supply is alternating current, the LED lamp string further comprises an AC/DC module;

when the connected power supply is direct current or alternating current, the LED light string further comprises a current limiting IC.

It can be understood that when an AC/DC module is included, it is to drive the LED luminary in the LED module by direct current. If not, the alternating current can be directly adopted to drive the LED luminous body, and human eyes can not find the flash of the LED according to the Hertz of the alternating current. When a current limiting IC is included, it means that the value of the current flowing in each LED luminary can be limited.

It should be noted that, when the LED luminary in the LED module further includes a current-limiting IC, this is particularly significant for high-voltage power supply, because: when the front cascade and the rear cascade are selected to be in parallel cascade, each LED luminous body can have the same voltage, and the current and the power of each LED luminous body can be accurately controlled by limiting the current, so that the LED luminous body has the advantage of only accurately controlling the current compared with a series high-voltage scheme in the prior art. That is, the present invention can achieve a better: high voltage, low power, precision controlled LED lighting solutions. In addition, the parallel LED illuminating product with longer length can be realized, especially, the parallel LED illuminating product with longer length can be realized on the premise that the voltage of each parallel branch circuit is equal on the premise that the total power is constant because the micro current enables the power of each branch circuit to be relatively low as long as the LED can still meet the visual brightness under the condition that the current is limited to the extremely micro current. It can be understood that when AC power supply is used, one end and the other end of the LED lamp string can be respectively connected with a zero-live wire; when the DC power supply is used, one end and the other end of the LED lamp string can be respectively connected with the positive and negative power supply wires. In addition, the LED luminous body also comprises an LED chip.

It is also particularly emphasized that the current limiting IC is preferably a constant current IC. Illustratively, the constant current IC provides 0.6-0.8mA and is at 110V, so that the LED luminary operates at very low power and is not burned out. It can be understood that by configuring a certain number of LED chips, the product of the present invention can operate at a voltage of 110V or the like without being burnt out, and is beneficial to extending parallel LED lighting for a sufficient length.

Even if the LED module comprises 3 LED luminous bodies, when the LED luminous bodies are connected in parallel, any one LED luminous body is cut from the LED lamp string of the LED lamp, under the premise of keeping the electrode wires at the two sides of the LED luminous body, the LED luminous body is connected to the alternating current of 110V or 230V, as long as the LED luminous body does not have a fault, a loop can be formed to enable the LED luminous body to emit light, and the LED luminous body can be molded again. By contrast, a series LED luminary cannot do this, because a plurality of LED luminaries connected in series as a whole can only operate at 110V or 230V, and if one LED luminary is directly cut off and connected to 110V and 230V, the LED luminary will burn out with a high probability. It is understood that the present invention is not limited to voltages of 110V, 230V, etc., and may be other power supply voltage standards or a wider voltage range.

Therefore, under the condition of parallel connection, each LED luminous body can be freely cut by the LED module, and after the LED luminous bodies are cut, the requirement of power supply voltage can be met under the condition that the LED luminous bodies are connected with a power supply. In addition, when the LED luminous body fails, the failed LED luminous body can be freely cut off and the original front and rear sections can be continued, and under the condition of not losing much length, the LED luminous body can continuously work under the same power supply voltage, and the consistency of the visual effect of illumination, namely the brightness can be maintained.

Fig. 2 is a schematic structural diagram of the LED light 120 in the LED lamp module according to the present embodiment at a first viewing angle. In the present embodiment, a light emitting chip 128 is disposed in the LED luminary 120, and the LED luminary 120 emits light through the light emitting chip 128. The light emitting chip 128 is a high voltage chip, so that even though the LED luminaries 120 in the module 100 of the LED lamp are connected in parallel, a high voltage product can be formed, and when the LED lamp is used, the mains supply is not required to be converted into a low voltage below a safe voltage by using a transformer, so that the power supply requirement can be met, and the problem of energy consumption increase caused by low conversion efficiency in the conversion process is avoided. It should be noted that high voltage chips are prior art, and the present invention does not attempt to provide new high voltage chip technology.

Further, the number of the light emitting chips 128 is plural, and the plural light emitting chips 128 are connected in series with each other, so that the required voltage of the single LED luminary 120 can meet the requirement. Illustratively, the number of the light emitting chips 128 is three, and the three light emitting chips 128 are connected in series, so that the voltage is the sum of the voltages of the three light emitting chips 128. It is understood that in other embodiments, the number of the light emitting chips 128 may be set according to the voltage of the desired LED luminary 120, for example, the number of the light emitting chips 128 is set to one, two or four, etc.

Further, the LED luminary 120 further includes a current limiting IC 127, the current limiting IC 127 is connected in series with the light emitting chip 128, and the current limiting IC 127 is configured to ensure that the current output by each LED luminary 120 is kept consistent. Meanwhile, when the head and the tail of the module 100 of the LED lamp are within the working voltage range of the current-limiting IC 127, the brightness of the LED luminous bodies 120 at the head and the tail of the module 100 of the LED lamp can be kept consistent.

Specifically, the LED luminary 120 includes a support 121, and a first substrate 122 and a second substrate 123 disposed on the support 121, a current limiting IC 127 is disposed on the first substrate 122, and light emitting chips 128 are each disposed on the second substrate 123.

Fig. 3 is a schematic structural diagram of the LED illuminator 120 in the module of the LED lamp provided in this embodiment under a second viewing angle, specifically, fig. 2 shows a front structure of the LED illuminator 120, and fig. 3 shows a back structure of the LED illuminator 120. Referring to fig. 2 and 3, in the present embodiment, the LED luminary 120 is a double-sided light emitting luminary, so that the light emitting range of the luminary is wider and the using effect is better.

Specifically, the support 121 of the LED luminary 120 has a first cup 124 and a second cup 125 disposed back to back, and a transparent layer 126 is disposed between the first cup 124 and the second cup 125, such that light emitted from the first cup 124 can exit the second cup 125 through the transparent layer 126, or light emitted from the second cup 125 can exit the first cup 124 through the transparent layer 126.

Alternatively, a portion of the first substrate 122 and a portion of the second substrate 123 form a portion of the bottom wall of the first cup 124, respectively, the light emitting chip 128 is disposed in the first cup 124 and is solder-fixed to the second substrate 123, while the current limiting IC 127 is disposed in the first cup 124 and is solder-fixed to the first substrate 122. The transparent layer 126 is disposed between the first substrate 122 and the second substrate 123, that is, light emitted by the light emitting chip 128 in the first cup 124 passes through the transparent layer 126, enters the second cup 125, and is emitted out, so as to achieve the effect of double-sided light emission. Specifically, the transparent layer 126 is made of a material with a certain transmittance.

Be provided with the diffusion layer in the second cup 125, the diffusion layer is made by diffusion material, and the light that gets into second cup 125 from first cup 124 when outwards emiting diffuses through diffusion material in the diffusion layer to the luminous effect that makes LED luminous element 120 send from the back differs little with the luminous effect that the front sent, thereby promotes LED luminous element 120's light efficiency.
