The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, an embodiment of the present invention provides an illumination lamp 10, comprising: a non-light transmissive panel 11 comprising opposite front and back sides; the circuit board 12 is provided on the back surface of the non-light-transmitting panel 11, the LED lamp 13 is provided on at least one side surface of the circuit board 12, and the light-transmitting propagation element 14 is provided on the outer cover of the LED lamp 13.
It should be noted that, in use, the illumination lamp 10 provided in the embodiments of the present invention has the front surface and the back surface opposite to each other, and the front surface of the non-transparent panel 11 faces the observer, so as to avoid intense light glare. The light-impermeable properties of the non-light-permeable panel 11 are not absolute and have a high-low score. In fig. 1, reference numeral 16 denotes a double-sided tape, and only one of the connection modes is shown, and the double-sided tape is not only present between the light-impermeable panel 11 and the wiring board 12, but also between the wiring board 12 and the propagation element 14 and between the light-impermeable panel 11 and the propagation element 14.
The non-light-transmitting panel 11 may be made of glass, stainless steel, plastic, or other light-transmitting materials, and the non-light-transmitting panel may be obtained by coating the non-light-transmitting materials such as glass and plastic, or the non-light-transmitting materials such as stainless steel, which do not have light-transmitting properties, may be obtained without coating the non-light-transmitting materials, but the above-mentioned coating may be used to print a pattern on the front surface of the non-light-transmitting panel 11 to increase the visibility and decoration of the panel. The non-light-transmitting panel 11 can prevent light rays emitted by the LED lamp 13 from directly entering eyes of an observer to a great extent, so that damage of the light rays to the eyes can be reduced, and the visual effect is better. The non-transparent panel 11 includes relative front and back, and the back of non-transparent panel 11 is located to circuit board 12, sets up LED lamp 13 on at least one side of circuit board 12 to guarantee the luminous demand of light 10, when the quantity of LED lamp 13 is a plurality of, LED lamp 13 evenly distributed on the side of circuit board 12, in order to realize the even effect of light, LED lamp 13 can reduce the energy consumption simultaneously, has also saved the cost. The LED lamp 13 is covered with a light-transmitting propagation element 14, which is understood to cover or house the outside of the LED lamp 13. The light emitted by the LED lamp 13 can be transmitted to the external environment by the transmitting element 14, and the light is softer than the effect of directly emitted from the LED lamp 13. When the light-impermeable performance of the non-light-permeable panel 11 is high, the observer cannot observe light from the outline of the non-light-permeable panel 11, but due to the presence of the propagation element 14, an aperture, resembling a solar halo, can be observed outside the outline of the non-light-permeable panel 11; when the light-non-transmitting performance of the light-non-transmitting panel 11 is low, the observer can observe the same light-emitting region as the shape of the propagation element 14 from the front surface of the light-non-transmitting panel 11, and at this time, the shape of the propagation element 14 affects the light-emitting region of the LED lamp 13 to some extent. By changing the shape of the propagation element 14, decorative effects can be achieved at the same time as auxiliary illumination.
The technical scheme at least has the following technical effects: the lighting lamp 10 provided by the technical scheme comprises a non-light-transmitting panel 11, a circuit board 12 arranged on the back surface of the non-light-transmitting panel 11, an LED lamp 13 arranged on the circuit board 12 and a light-transmitting propagation element 14 covered outside the LED lamp 13, wherein the light transmitted by the LED lamp 13 can be propagated to the external environment through the light-transmitting propagation element 14, the light-emitting area of the LED lamp 13 can be determined to a certain extent by the shape of the propagation element 14, so that the shape of the appropriate propagation element 14 can be selected according to actual requirements, and the light transmitted through the propagation element 14 is more uniform and softer. The non-light-transmitting panel 11 can prevent light rays emitted by the LED lamp 13 from directly entering eyes of an observer to a great extent, so that damage of the light rays to the eyes can be reduced, and the visual effect is better.
The following two specific examples are provided to illustrate, but not limit, other embodiments of reasonable variations on the following examples, which are also within the scope of the present invention.
Referring to fig. 2 to 8, in the illumination lamp 100 provided in the first embodiment, the circuit board 12 is a single-sided circuit board 120, and the single-sided circuit board 120 has a printed surface, which is a back surface facing away from the non-transparent panel 110, and the printed surface is provided with the LED lamp 130. The propagation element is a lens 140, and the non-light-transmitting panel 110, the single-sided wiring board 120, and the lens 140 are stacked in this order. So set up, the light direction that LED lamp 130 sent deviates from the front of non-printing opacity panel 110, is the same with the viewing direction of eyes, and the light that LED lamp 130 sent can not directly penetrate into observer's eyes, and light is even soft, can reduce the injury of light to eyes, and the visual effect is better.
Specifically, referring to the different viewing angles shown in fig. 1 and 2, the non-transmissive panel 110 includes opposite front and back sides, and the single-sided circuit board 120 is laminated to the back side of the non-transmissive panel 110. The single-sided circuit board 120 has a printed surface facing away from the back surface of the non-transparent panel 110, and is uniformly provided with a plurality of LED lamps 130, so that the emitted light is more uniform, and meanwhile, the LED lamps 130 can reduce energy consumption to a certain extent, and save cost. The lens 140 may be formed by injection molding of a milky white optical material, the lens 140 is provided with a concave portion for accommodating the LED lamp 130, a portion of the lens 140 outside the concave portion is attached to the circuit board, and at the same time, a portion of the lens 140 outside the single-sided circuit board 120 may be directly attached to the non-light-transmitting panel 110, and the shape of the lens 140 is substantially the same as that of the single-sided circuit board 120, so as to form a light emitting region of the LED lamp 130.
For traditional LED pointolite or the direct eyes of penetrating into the observer of light that the area source sent, in this embodiment, because the printing surface of single face circuit board 120 deviates from non-printing opacity panel 110, LED lamp 130 locates on the printing surface, the light that LED lamp 130 sent can not be towards observer's eyes, when observing from non-printing opacity panel 110's front, refer to FIG. 13, the light direction that LED lamp 130 sent is the same with the direction of observation of eyes, the light that LED lamp 130 sent can not directly penetrate into observer's eyes, the light is even soft, can reduce the injury of light to eyes, visual effect is better. Meanwhile, under the condition of ensuring a certain lighting function, the decorative effect can be achieved.
Referring to fig. 6 to 8, a surface of the lens 140 opposite to the single-sided wiring board 120 is formed with protrusions 142 and grooves 144 alternately arranged in order. In order to make the light distribution more uniform, the surface of the lens 140 facing the single-sided circuit board 120 is provided with protrusions 142 and grooves 144, which increase the number of refraction and reflection of the light, and increase the density of the light passing through the inner surface of the lens 140, so that the light emitted from the lens 140 is more uniform.
Referring to fig. 3 and 4, a gap is provided between the lens 140 and the LED lamp 130. In this way, the mechanical damage caused by the contact between the lens 140 and the LED lamp 130 due to vibration or external pressure can be reduced, and the damage rate of the LED lamp 130 is reduced, thereby saving maintenance cost.
Referring to fig. 2, 5 and 6, the single-sided wiring board 120 and the lens 140 are each ring-shaped. In order to reduce the number of the LED lamps 130 and reduce the cost and the influence on the luminous intensity, as shown in fig. 2, the single-sided circuit board 120 and the lens 140 are both in a ring shape, such as a circular ring, a square ring or other shapes, and when the light-proof performance of the non-transparent panel 110 is low, the shape of the single-sided circuit board 120 determines the luminous area of the LED lamps 130, that is, the luminous area of the LED lamps 130 is also in a ring shape, so that a certain range of luminous area can be ensured, and a better decorative effect is achieved. In order to allow the single-sided wiring board 120 to be completely covered by the lens 140 without exposure to air, the annular contour of the lens 140 is set to be larger than the annular contour of the single-sided wiring board 120, and the portion of the lens 140 other than the portion covering the single-sided wiring board 120 is directly bonded to the non-light-transmitting panel 110. In addition, the annular single-sided circuit board 120 and the annular lens 140 occupy a larger circumferential area, so that the thickness of the overall lighting lamp 100 can be made thinner, and the lighting defect of the LED lamp 130 can be reduced.
Further, since the annular lens 140 is bulky and is easily damaged in production and preparation, a partial shape of the lens 140 can be formed in injection molding, and then it is spliced into a complete lens 140 by using glue, double-sided tape, or the like. For example, as shown in fig. 6 and 7, a U-shape may be formed, with two U-shapes mirror-spliced into a ring-shaped lens 140.
Referring to fig. 9 and 10, in the illumination lamp 200 provided in the second embodiment, the circuit board 12 is a double-sided circuit board 220, and the double-sided circuit board 220 has two opposite printed surfaces, and each printed surface is provided with an LED lamp 230; the propagation element is a light guide 240, the thickness direction of the double-sided circuit board 220 is perpendicular to the thickness direction of the light guide 240, and the double-sided circuit board 220 is sandwiched between the non-transparent panel 210 and the light guide 240. So set up, the light that LED lamp 230 sent is on a parallel with non-printing opacity panel 210, can not directly penetrate into observer's eyes, and light is even soft, can reduce the injury of light to eyes, and the visual effect is better.
Specifically, referring to the different viewing angles shown in fig. 1 and 9, the non-transparent panel 210 includes opposite front and back surfaces, the double-sided circuit board 220 is disposed on the back surface of the non-transparent panel 210, and the double-sided circuit board 220 has two opposite printed surfaces, each of which is provided with a plurality of LED lamps 230, so that the double-sided circuit board 220 has a double-sided light emitting effect. The light guide 240 employs a light guide material such that light emitted from the LED lamp 230 can form a desired light emitting area along the shape of the light guide material. The thickness direction of the double-sided circuit board 220 is perpendicular to the thickness direction of the light guide 240, that is, the two printed surfaces are perpendicular to the light guide 240, and the light emitted by the LED lamps 230 on the two printed surfaces is refracted and totally reflected along the shape of the light guide 240 in opposite directions to realize the transmission of the light, so that the light guide 240 emits light in a large area. Since the light guide 240 has a light guiding effect, a small number of LED lamps 230 can be used to realize large-area light emission of the light guide 240, thereby reducing the cost. The double-sided circuit board 220 is sheet-shaped, and can be attached to any contour of the light guide member 240 due to the thinner thickness, or a pit is formed on the light guide member 240, and the double-sided circuit board 220 is arranged in the pit, so that more light enters the light guide member 240, and the distance between the non-transparent panel 210 and the light guide member 240 is reduced.
Compared with the conventional LED point light source or the light emitted by the surface light source is directly injected into the eyes of the observer, in this embodiment, since the thickness direction of the double-sided circuit board 220 is perpendicular to the thickness direction of the light guide 240, the light emitted by the LED lamp 230 can be transmitted along the shape of the light guide 240, so that the light diverges along the shape of the light guide 240, when the light is observed from the front side of the non-transparent panel 210, referring to fig. 14, the light emitted by the LED lamp 230 is not directed towards the observation direction of the eyes, but is parallel to the non-transparent panel 210, the light emitted by the LED lamp 230 is not directly injected into the eyes of the observer, the light is even and soft, the damage of the light to the eyes can be reduced, and the visual effect is better. Meanwhile, under the condition of ensuring a certain lighting function, the decorative effect can be achieved.
Further, the light guide 240 is annular, and the projection profile of the double-sided circuit board 220 on the light guide 240 does not exceed the profile of the light guide 240. In order to reduce the number of the LED lamps 230 and reduce the cost and the influence on the luminous intensity, the light guide 240 is formed in a ring shape, such as a circular ring, a square ring or other shapes, and when the light-tight performance of the non-transparent panel 210 is low, the shape of the light guide 240 determines the luminous area of the LED lamps 230, that is, the luminous area of the LED lamps 230 is also in a ring shape, so that a certain range of luminous areas can be ensured, and a better decorative effect is achieved. In order not to affect the visibility, the projection profile of the double-sided wiring board 220 on the light guide 240 does not exceed the profile of the light guide 240. Fig. 10 is merely an enlarged view of the double-sided circuit board 220 formed for explaining the positional relationship between the double-sided circuit board 220 and the light guide 240, and does not actually exceed the outline of the light guide 240. In addition, the annular light guide member 240 occupies a larger volume, so that the thickness of the overall illumination lamp 200 can be made thinner, the number of the LED lamps 230 is smaller, and the phenomenon that the LED lamps 230 have bright spot defects is reduced to a certain extent.
In other embodiments, the front surface of the non-transparent panel 11 is covered with an ink pattern layer to form a pattern with better visibility, and the pattern plays a good role in decoration. When the non-light-transmitting panel 11 is made of materials with lower light-proof performance such as glass and plastic, the ink pattern layer covered on the front surface of the non-light-transmitting panel 11 can play a role in decoration and shading so as to realize the light-proof function, and meanwhile, the ink layer is covered on the back surface of the non-light-transmitting panel 11 so as to enable the non-light-transmitting panel 11 to realize the light-proof function better and prevent light rays emitted by the LED lamps 13 from being directly injected into eyes. For example, the non-light-transmitting panel 11 is a glass panel made of food-grade tempered glass, and a food-grade high-temperature ink pattern is printed on the front surface, so that when an observer faces the illuminating lamp 10, the ink pattern layer plays a good decorative role, and the ornamental performance is improved. Black ink is printed on the back to prevent light from the LED lamp 13 from directly entering the eyes of the observer through the glass panel.
In other embodiments, the circuit board 12 is further provided with a resistive element 15 in series with the LED lamp 13. The resistor element 15 can be a chip resistor or a welding resistor, is connected in series with the LED lamp 13, and has the function of voltage division, so that the LED lamp 13 is prevented from being burnt due to overlarge current. As shown in fig. 5, the resistor element 15 is a chip resistor 150.
In other embodiments, the propagation element 14 is completely attached to the circuit board 12, and the propagation element 14 is attached to the non-light-transmitting panel 11 in a portion other than the portion to which the circuit board 12 is attached. In the first embodiment, the lens 140 is bonded to the non-light-transmitting panel 110 in a portion other than the portion bonded to the single-sided wiring board 120.
