Description

Solar luminous road brick with light guiding and distributing functions for landscape brightening

Technical Field

The utility model relates to a solar luminous road brick; and more particularly, to a solar light emitting road brick having light guiding and distributing functions.

Background

The solar luminous road brick with the LED illumination function is used for paving a road surface, so that solar energy can be converted into electric energy required by LED illumination, energy is saved, and the LED illumination can realize the change of color, brightness and/or illumination patterns under the control of a control center, thereby providing an intelligent indication/illumination function and playing a role in landscape brightening.

Most of the existing solar energy luminous road bricks adopt LED point light sources as luminous sources. For example, the solar light-emitting road bricks disclosed in chinese patent documents CN202073003U, CN206127825U, CN205474712U and CN205480763U all have upward-illuminating LED point light sources, and light emitted from the LED point light sources passes through the road brick panel upward and then is emitted to the outside, so that the whole light-emitting road brick looks like light spots only at the respective LED point light sources, and eyes look directly with dazzling and vertigo feeling. Although the road brick panel can usually be made with uneven anti-skid patterns or frosted to achieve the anti-skid effect, the road brick panel with the anti-skid patterns or frosted can only locally emit light to shine, the whole road brick panel cannot shine, the problems of uneven light emission and poor lighting effect exist, and the decorative effect is not ideal.

Aiming at the problems, some existing luminous road bricks adopt a light homogenizing structure. For example, chinese patent document CN201671297U provides a backlight type LED lighting road brick; as shown in fig. 1, the LED module comprises a shell 1 with a single-sided opening, a light-transmitting body 2 buckled at the opening of the shell 1, an LED 3 and a circuit board 4 for welding and fixing the LED 3, wherein the circuit board 4 is fixedly arranged on the inner side of the shell 1; a light guide plate 5 for transmitting light generated by the LEDs 3 is mounted and fixed below the light-transmitting body 2, and the LEDs 3 are arranged on a side surface of the light guide plate 5. When the LED backlight street lamp is used, light generated by the LED 3 enters the side face of the light guide plate 5 in an irradiating mode, so that the light guide plate 5 uniformly emits light, and then the light penetrates through the light transmitting body 2 to be irradiated out, and therefore the LED backlight board type light-emitting street lamp is formed.

For another example, chinese patent document CN205529749U provides a solar street tile provided with a light-diffusing sheet. As shown in fig. 2, the solar cell comprises a casing 1, a light source 2, a solar circuit board and a battery are arranged in the casing 1, a light transmission layer 3 is arranged above the light source 2, and a light scattering layer 4 is arranged below the light transmission layer 3; the light emitting source 2 comprises a plurality of LED blue and white lamps arranged in a matrix, one side of the light scattering layer 4 close to the light transmitting layer 3 is a plane, and one side of the light scattering layer 4 close to the light emitting source 2 comprises a plurality of light scattering units which are closely arranged; and the shell 1 and the euphotic layer 3 are sealed by glue.

In the above two patent documents, a light guide plate or a light diffusion layer is additionally provided on the upper portion of the LED light source, thereby achieving a light uniformizing effect. However, in order to make the light-diffusing layer and the light-guiding plate emit light uniformly, the light-emitting surface of the light-diffusing layer and the light-guiding plate need to be provided with an optical structure for light-uniformizing, and due to the existence of the optical structure, the light-emitting surface of the light-diffusing layer and the light-guiding plate cannot be directly packaged into a whole, a medium (such as air) with a low refractive index must be separated between the light-emitting surface and the light-uniformizing plate, and if the light-emitting surface and the light-uniformizing plate are packaged together by a packaging material (such as silica gel) with a higher refractive.

Further, in the above two patent documents, the LED and the circuit board are disposed in the hollow cavity of the road brick, the weight borne by the road brick panel is transferred downward through the surrounding frame portion, and the stress of the road brick panel is concentrated on the contact portion between the surrounding and the frame, so that the road brick panel is easily broken due to the simultaneous action of pressure and shearing force. Moreover, at this moment, the frame is very stressed, especially considering the current situation that the road surface usually paved by the luminous road bricks can be driven by non-motor vehicles or even provided with motor vehicle parking spaces, if the frame is repeatedly impacted and rolled with high strength, the frame can be deformed, damaged or even broken in a short time, and even a very small deformation of the frame can damage the waterproof structure depending on the frame.

In view of this, chinese patent document CN108302425A proposes a diffuse reflection type solar energy luminous road brick. As shown in fig. 3, the light-emitting road brick comprises a bottom plate 5, a light-transmitting rigid panel 3, a light-transmitting packaging material layer 4, a photovoltaic cell 1 and an LED light source 2, wherein the LED light source comprises a circuit board and an LED light-emitting element arranged on the circuit board; the packaging material layer 4 is arranged between the bottom plate 5 and the hard panel 3 and is tightly contacted with the bottom plate 5 and the hard panel 3; the photovoltaic cell 1 is encapsulated in a layer of encapsulating material 4; one side of the hard panel 3 adjacent to the packaging material layer 4 is provided with a groove, and the LED light-emitting element is arranged in the groove and is configured to emit light towards the side direction of the light-emitting road brick; the remaining space in the groove is filled with a light transmissive potting material.

In the solar light-emitting road brick, the hard panel, the packaging material layer and the bottom plate are in close contact, the hard panel, the packaging material layer and the bottom plate form a light guide layer, the upper surface of the hard panel is densely covered with uneven anti-skid patterns and/or frosted to form a light emitting surface of the light guide layer, the upper surface and/or the lower surface of the bottom plate form a reflecting surface of the light guide layer, light emitted by the LED light-emitting element emitting light in the lateral direction is transmitted in the light guide layer, and finally the light is uniformly emitted through the upper surface (the light emitting surface of the light guide layer) of the hard panel.

The solar luminous road brick also has a need for improvement. For example, in the light emitted from the LED light emitting element emitting light laterally, in the area close to the LED light emitting element, the incident angle of a large amount of light reaching the light exit surface (the upper surface of the rigid panel) is larger than the critical angle of the light guiding layer, which causes the direct emission of the light, so that the brightness of the area close to the LED light emitting element is significantly higher than that of the area far from the LED light emitting element, and the light emission of the entire rigid panel is still not uniform enough; in order to improve the power generation efficiency of the photovoltaic cell, the absorption rate of the upper surface of the photovoltaic cell is usually high, so that part of light rays are shielded and absorbed by the photovoltaic cell before reaching the reflecting surface, and the light rays are rapidly attenuated, so that the brightness of an area close to an LED light-emitting element is higher than that of an area far away from the LED light-emitting element, the non-uniformity of light emission of a hard panel is aggravated, and the brightness of the whole road brick panel is reduced; one side of the hard panel adjacent to the packaging material layer is provided with a groove, and the groove has certain influence on the strength of the hard panel and can damage the bearing strength of the whole road brick.

Detailed Description

Example 1

Fig. 4 shows the structure of the solar light-emitting road brick of the present invention in embodiment 1, and fig. 5 is a partially enlarged view of the LED light source portion thereof.

The light scattering/refracting structures 9 are distributed on the surface of the light distribution layer 5, and the light scattering/refracting structures 9 can be small-size concave points, concave lines or concave surfaces which are processed on the surface of the light distribution layer 5 and have rough surfaces, or small-size light-tight or semi-light-tight convex points, convex lines or convex surfaces which are processed on the surface of the light distribution layer 5. For the concave light scattering/refracting structure 9, because the surface roughness is high and the size is small, in the packaging process, the packaging material can not completely soak the surface, partial air still remains between the surface and the packaging material, and when the LED light passes through the residual air, the LED light is scattered, so that a tiny light emitting point is formed, and the brightness of the area nearby the tiny light emitting point is increased. For the convex light scattering/refracting structures 9, due to the opaque or semi-opaque property, when LED light passes through these convex light scattering/refracting structures 9, the LED light is also scattered, thereby increasing the brightness of the area nearby.

The light scattering/refracting structures 9 may be distributed over the upper surface of the light-distributing layer 5, over the lower surface or on both surfaces. The light scattering/refracting structures 9 may be uniformly distributed on the surface of the light distribution layer 5, or may be non-uniformly distributed or form a pattern shape.

The accommodating grooves 10 are arranged according to the arrangement positions of the LED lamp beads 7, can be linear, arc-shaped or curved grooves which are consistent with the trend of the LED circuit board 8, and can also be point-shaped grooves corresponding to the positions of the LED lamp beads 7; the cross section of the accommodating groove 10 can be V-shaped, U-shaped, semicircular or other shapes capable of accommodating the LED lamp beads 7.

The LED lamp beads 7 are arranged in the accommodating grooves 10 and are configured to emit light towards the horizontal inner side of the solar light-emitting road brick; the remaining space in the housing groove 10 is filled with a translucent potting material that connects the LED light source 2 and the light distribution layer 5 together while exhausting air in the housing groove 10. The potting material may be a liquid curing type (e.g., potting compound, UV paste, etc.) potting material, or a hot melt type (e.g., EVA, etc.) potting material. The potting material may be the same as or different from the materials of the first and second encapsulant layers 41 and 42.

In the daytime, sunlight needs to penetrate through the hard panel 3 to irradiate the photovoltaic cell 1 to generate electric energy; at night, the light emitted by the LED light source 2 needs to penetrate the hard panel 3 to be uniformly irradiated, so that the hard panel 3 is a tempered glass panel with high transmittance. In order to meet the design and construction specification requirements of municipal roads, the upper surface of the hard panel 3 needs to be subjected to anti-skid treatment, such as processing into uneven anti-skid patterns or sanding treatment, and the anti-skid treatment method is not limited to the two methods. In addition, the bottom plate 6 can also be made of toughened glass.
