Light guide body covered with optical membrane

Abstract

The invention discloses a light guide body covered with an optical membrane. The light guide body comprises a transparent solid geometry and an optical membrane and is characterized in that: the optical membrane is covered on the outer surface of the transparent sold geometry with the thickness of over 1 mm; in the solid geometry, at least one outer surface is an incident face; at least one outer surface is a light emitting surface; the solid geometry at least comprises a medium membrane material optical membrane layer of submicron particles or nano-particles; and the thickness of the membrane is between 91 nm and 5 mm. The invention aims to cover a matched optical membrane by a well-known coating method on the outer surfaces of sold geometries with different optical functions, so that the light guide body with higher efficiency and more functions is possible to realize. The light guide body can match a light-emitting diode (LED) light source for using, match other various light sources to be used in lighting and display light fittings and backlight, and also can be made into purification light fittings, sterilization light fittings, phototherapy light fittings, plant illumination light fittings and the like. Along with the development of an electronic membrane technology, more commercial opportunities for light guide body application products can be exploited.

Description

technical field [0001] The invention relates to a light guide body, in particular to a light guide body covered with an optical film layer and a manufacturing method, which can be widely used in various technical fields related to surface light sources such as display, lighting, and backlight source. Background technique [0002] Disclosed by Chinese invention patent CN100508222C: the energy utilization rate of surface light source devices based on light-emitting diodes that have appeared is still relatively low. On the one hand, because the LED manufacturing technology itself is still developing, there is still a lot of room for improvement in its power efficiency (Wall-Plug Efficiency); on the other hand, the secondary packaging efficiency ( Secondary efficiency for short) is still relatively low, and the low light guide efficiency of the light guide plate in the light guide body is an important reason. The light guide efficiency of the light guide plate is defined as the...

Problems solved by technology

Although the light guide efficiency can be maximized by optimizing the design of the scattering mechanism layer and the scattering unit, since the light will inevitably transmit from the main surface opposite to the main exit surface and become invalid exit light, there is a principle of its light guide efficiency. upper limit and cannot reach higher

[0004] The current light guide is limited to plate-shaped light guide plates. The light guide technology is made by mechanical engraving, printing dots, laser engraving, and special light guide plate structures. There are still complex manufacturing processes, high costs, and low cost performance. It is difficult to break through the upper limit of the above-mentioned theoretical light guide efficiency, and at the same time, the plate-shaped light guide body, that is, the application surface of the light guide plate, is also subject to certain restrictions.
