Summary of the invention
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of surface light emitting evenly, the slim light guide formula luminescent screen of energy saving.
The purpose of this utility model can be achieved through the following technical solutions: a kind of slim light guide formula luminescent screen, it is characterized in that, comprise a screen board, at least one linear light sorurce, at least one reflectorized material, the described screen board back side is processed with the refraction striped, described linear light sorurce is located at the side of screen board, and one of them is located at the bottom of above-mentioned refraction striped described reflectorized material.
Described refraction striped is serrate or half round post or square column type.
Described refraction striped ends to the another side by dredging gradually solid matter cloth or evenly arranging from linear light sorurce, and this refraction striped can be separated from each other or overlap.
Described linear light sorurce directly embeds the side of screen board.
Also comprise support, this support is installed in the side of screen board, and described linear light sorurce is located on the support.
One of them is located at side relative with linear light sorurce on the screen board described reflectorized material.
Described linear light sorurce sets up one, two, three or four separately according to the size of screen board, is located at a side, two sides, three sides or four sides of screen board respectively.
Also comprise light-transmissive film or printing opacity reflective membrane, described light-transmissive film or printing opacity reflective membrane are located at the front of screen board.
Described screen board adopts the sheet material that pure transparent logical light rate is high and be convenient to process, and comprises acrylic sheet material or polystyrene plates.
Described linear light sorurce adopts fluorescent tube or cold-cathode tube or light emitting diode or luminescent lamp strip.
Compared with prior art, screen board of the present utility model adopts pure transparent acrylic sheet material or polystyrene leaded light sheet material, and process the refraction striped at the screen board back side with the mode of machining or Laser Processing and cover reflectorized material, under the situation of the linear light source igniting in side, this screen board is under leaded light, refractive power and reflective combined action, make line source be transformed into area source, and be mapped in the surface of screen board equably.It uses the refraction and the principle of reflection of light dexterously, makes the surface of screen board can do greatlyyer, and thickness can be done very for a short time, thereby has improved the utilization factor of light source; Saved the energy, it can be widely used in LCDs background light source, advertising signboard, emergent guiding direction board, guideboard, public transport stop board and automotive number plate or the like.
