Two specific examples are provided below for illustration, and other embodiments reasonably modified based on the following examples are also within the scope of the present invention and are not limited to the contents described in the following examples.

Referring to fig. 2 to 8, in the illumination lamp 100 according to the first embodiment, the circuit board 12 is a single-sided circuit board 120, the single-sided circuit board 120 has a printed surface, the printed surface is a back surface facing away from the non-light-transmissive panel 110, and the printed surface is provided with the LED lamp 130. The transmission element is a lens 140, and the non-light-transmitting panel 110, the single-sided wiring board 120 and the lens 140 are sequentially stacked. So set up, the light direction that LED lamp 130 sent deviates from non-light-permeable panel 110's front, and 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 visual effect is better.

Specifically, referring to different viewing angles shown in fig. 1 and 2, the non-light-transmitting panel 110 includes opposite front and back surfaces, and the single-sided wiring board 120 is laminated to the back surface of the non-light-transmitting panel 110. The single-sided circuit board 120 has a printed surface facing away from the back surface of the non-light-transmitting panel 110, and is uniformly provided with a plurality of LED lamps 130, so that the emitted light is more uniform, and meanwhile, the use of 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, the lens 140 is attached to the circuit board at a portion outside the concave portion, meanwhile, the portion of the lens 140 outside the single-sided circuit board 120 may be directly attached and fixed 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, thereby forming a light-emitting region of the LED lamp 130.

For the eyes that the observer was directly penetrated to the light that traditional LED pointolite or area source sent, in this embodiment, because the printing face of single face circuit board 120 deviates from non-light-transmitting panel 110, LED lamp 130 is located on the printing face, the light that LED lamp 130 sent can not be towards observer's eyes, when observing from non-light-transmitting panel 110's front, refer to fig. 13, the light direction that LED lamp 130 sent is the same with the viewing direction of eyes, the light that LED lamp 130 sent can not directly penetrate into observer's eyes, 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, the surface of the lens 140 opposite to the single-sided wiring board 120 is formed with projections 142 and grooves 144 alternately arranged in this order. In order to make the light distribution more uniform, the surface of the lens 140 facing the single-sided board 120 is provided with the protrusions 142 and the grooves 144, so that the refraction and reflection times of the light are increased, and the density of the light passing through the inner surface of the lens 140 is increased, so that the light emitted from the lens 140 is more uniform.

Referring to fig. 3 and 4, the lens 140 has a gap with the LED lamp 130. Therefore, mechanical damage caused by contact between the lens 140 and the LED lamp 130 due to vibration or external pressure can be reduced, the damage rate of the LED lamp 130 is reduced, and the maintenance cost is saved.

Referring to fig. 2, 5, and 6, the single-sided wiring board 120 and the lens 140 are both ring-shaped. In order to reduce the number of the LED lamps 130 used, reduce the cost, and reduce the influence on the light emitting intensity, as shown in fig. 2, the single-sided circuit board 120 and the lens 140 are both formed in a ring shape, such as a circular ring, a square ring, or other shapes, when the light-tight performance of the non-light-tight panel 110 is low, the shape of the single-sided circuit board 120 determines the light emitting area of the LED lamp 130, that is, the light emitting area of the LED lamp 130 is also formed in a ring shape, so that a light emitting area in a certain range can be ensured, and a good decoration effect is achieved. In order to completely cover the single-sided board 120 with the lens 140 without exposing the single-sided board to the air, the annular contour of the lens 140 is set to be larger than the annular contour of the single-sided board 120, and the portion of the lens 140 other than the portion covering the single-sided board 120 is directly attached 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 entire illuminating lamp 100 can be made thinner and thinner, thereby reducing the occurrence of lighting defects of the LED lamp 130.

Further, since the annular lens 140 has a large volume and is easily damaged during production and preparation, a partial shape of the lens 140 can be formed during injection molding, and then the lens 140 can be spliced into the 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, and two U-shapes are mirror-spliced to form a ring-shaped lens 140.

Referring to fig. 9 and 10, in the illumination lamp 200 according to the second embodiment, the circuit board 12 is a double-sided circuit board 220, the double-sided circuit board 220 has two opposite printing surfaces, and each printing surface is provided with an LED lamp 230; the transmission 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-light-transmitting panel 210 and the light guide 240. So set up, the light that LED lamp 230 sent is on a parallel with non-light-transmitting panel 210, can not directly penetrate into observer's eyes, and light is even soft, can reduce the injury of light to eyes, and visual effect is better.

Specifically, referring to different viewing angles shown in fig. 1 and 9, the opaque panel 210 includes opposite front and back surfaces, the double-sided wiring board 220 is provided on the back surface of the opaque panel 210, the double-sided wiring board 220 has two opposite printed surfaces, each printed surface is provided with a plurality of LED lamps 230, and thus, the double-sided wiring board 220 has a double-sided light emitting effect. The light guide 240 is made of a light guide material, so 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 member 240, namely, the two printed surfaces are perpendicular to the light guide member 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 member 240 in two opposite directions to realize the transmission of the light, so that the light guide member 240 emits light in a large area. Since the light guide member 240 has a light guide function, a large area of light emission of the light guide member 240 can be achieved using a small number of LED lamps 230, thereby reducing costs. The double-sided circuit board 220 is formed in a sheet shape, and can be attached to any profile of the light guide member 240 due to its thin thickness, or a concave pit is formed in the light guide member 240, and the double-sided circuit board 220 is disposed in the concave pit, so that more light enters the light guide member 240, and the distance between the non-light-transmitting panel 210 and the light guide member 240 is reduced.

For the eyes that the light that traditional LED pointolite or area source sent directly jets into the observer, in this embodiment, because the thickness direction perpendicular to leaded light 240 of double-sided circuit board 220's thickness direction, consequently, the light that LED lamp 230 sent can be transmitted along the shape of leaded light 240, make light disperse along the shape of leaded light 240, when observing from the front of non-light-transmitting panel 210, refer to fig. 14, the light that LED lamp 230 sent does not face the viewing direction of eyes, but is on a parallel with non-light-transmitting panel 210, the light that LED lamp 230 sent can not directly jet into observer's eyes, 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.

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, reduce the cost, and reduce the influence on the light emitting intensity, the light guide 240 is made in a ring shape, such as a circular ring, a square ring, or other shapes, when the non-light-transmissive panel 210 has low non-light-transmissive performance, the shape of the light guide 240 determines the light emitting region of the LED lamp 230, that is, the light emitting region of the LED lamp 230 is also in a ring shape, so that the light emitting region in a certain range can be ensured, and a good decoration effect is achieved. In order not to affect visibility, the projected outline of the double-sided wiring board 220 on the light guide 240 does not exceed the outline of the light guide 240. Fig. 10 is an enlarged view of the double-sided wiring board 220 formed merely to explain the positional relationship between the double-sided wiring 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 whole illuminating lamp 200 can be made thinner, the number of the LED lamps 230 is smaller, and the phenomenon of bright spot defects of the LED lamps 230 is reduced to a certain extent.

in other embodiments, the front surface of the non-light-transmitting panel 11 is covered with an ink pattern layer to form a pattern with better visibility, which can perform a good decoration function. When the non-light-transmitting panel 11 is made of materials with low light-tight 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 also can play a role in shading to realize a light-tight function, and meanwhile, the ink layer is covered on the back surface of the non-light-transmitting panel 11 to enable the non-light-tight function of the non-light-transmitting panel 11 to be better, so that light emitted by the LED lamp 13 is prevented from directly entering eyes. For example, the non-light-transmitting panel 11 is a glass panel made of food-grade tempered glass, and the front surface of the non-light-transmitting panel is printed with food-grade high-temperature ink patterns, so that when an observer faces the illuminating lamp 10, the ink pattern layer has a good decorative effect, and the ornamental performance is improved. The back side is printed with black ink to prevent light from the LED lamp 13 from passing through the glass panel and directly entering the eyes of the viewer.
