Description

technical field [0001] The invention relates to a diffuse reflection landscape lighting and indication module for road surface based on solar energy and LED array, and a road landscape lighting and intelligent indication system constructed by the module. Background technique [0002] Using modules with LED lighting functions (light-emitting floor tiles) to pave roads can not only play a role in landscape lighting, but also LED lighting can achieve changes in color, brightness and / or lighting patterns under the control of the control center, thereby providing intelligent lighting. indication function. Considering energy saving and other aspects, photovoltaic cells can also be set in the luminous floor tiles to convert solar energy into electric energy required by LED lighting.

AI Technical Summary

Problems solved by technology

However, in order to uniformly emit light from the light-emitting layer and the light guide plate, an optical structure for uniform light is arranged on the light-emitting surface. It is precisely because of the existence of this optical structure that the light-emitting surface cannot be directly packaged with the floor tile panel as a whole. There must be a medium with low refractive index (such as air) between the surface and the floor tile panel. If the two are packaged together with a higher refractive index packaging material (such as silica gel), the optical structure of the light-emitting surface will be affected. Destroyed, no uniform light effect

Therefore, these two technologies have the problems of high cost (multiple use of light-scattering layers or light guide plates), and not compact structure (cannot be directly packaged into a whole)

[0011] In addition, in the above existing technologies, an additional waterproof layer (or water-proof layer) or additional waterproof sealing treatment (glue sealing) is required, and the sealing and waterproof effect of the packaging material for packaging photovoltaic cells is not fully utilized, and the cost is high.

Moreover, in the case of waterproof sealing treatment, since there is a hollow space filled with gas inside the luminous floor tiles, when the ambient temperature changes, the internal air pressure changes caused by the thermal expansion and contraction of the gas can easily cause the seal to fail, resulting in the weather resistance of the floor tiles. Poor waterproof effect

[0012] Secondly, when the part where LEDs and circuits are arranged is hollow, the weight of the floor tile panel is transmitted downwards through the surrounding frame parts, and the force of the floor tile panel is concentrated on the parts around it that are in contact with the frame, causing the glass cover to be under pressure at the same time. Easily broken by shear force

Moreover, at this time, the frame is subjected to a very large force, especially considering that the sidewalks usually laid by luminous floor tiles may have non-motor vehicles driving or even have parking spaces for motor vehicles. It will be deformed, damaged or even broken, and even a small deformation of the frame will destroy the waterproof structure that depends on the frame

[0013] Furthermore, the above prior art also has the problem that the overall design of the luminous floor tiles is not compact enough, resulting in a thicker structure, inconvenient laying, and increased costs
