Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples.
Referring to fig. 1 to 4, an embodiment of the low temperature light emitting module of the present invention includes a low temperature light emitting device 2, a package layer 3 covering the outermost periphery of the low temperature light emitting device 2, and a frequency converter 4.
The package layer 3 is made of a transparent polymer material and has flexibility to cover and protect the low-temperature light emitting device 2 without affecting the light emission of the low-temperature light emitting device 2.
The frequency converter 4 is electrically connected to the low-temperature light-emitting component 2 to provide proper working voltage pulse frequency and current condition, so that the light-emitting material in the low-temperature light-emitting component 2 generates oxidation-reduction reaction to emit light.
The low-temperature light-emitting component 2 comprises a substrate 21, a first electrode 22, a light-emitting unit 23, a second electrode 24 and an electrical connection unit 25.
The base material 21 is a light-transmitting flexible material, and includes a first base film 211 and a second base film 212 sequentially stacked, wherein the first base film 211 can be made of a conventional transparent polymer material, and the second base film 212 can be made of rice paper.
The first electrode 22 is formed on the surface of the substrate 21, and is in a frame shape and partially overlaps the outer edge of the light-emitting unit 23. In the present embodiment, the first electrode 22 is formed on the surface of the second base film 212, and the material of the first electrode 22 is conductive silver paste.
The light emitting unit 23 is disposed on the surface of the substrate 21, and has at least one light emitting layer 231 containing an organic light emitting material obtained by fermenting an organic substance, and the periphery of the light emitting layer 231 and the first electrode 22 are overlapped and connected with each other.
The organic luminescent material is prepared from organic materials such as vegetables, fallen leaves and kitchen residues through refining, fermenting, filtering and other treatment processes, and then luminescent raw materials such as protease, saccharides, alcohols, aldehydes, phenols, iodine mixtures and benzene mixtures are obtained. The organic light-emitting material can perform biological oxidation-reduction reaction to emit light after being excited by external pulse frequency (>6000Hz), and the light-emitting principle is similar to the biological fluorescence light-emitting principle of the biological world, such as firefly, rainforest mushrooms, lantern fishes, jellyfish and the like, so that the light-emitting unit 23 has extremely low heat energy and good light-emitting efficiency when emitting light.
The second electrode 24 is made of the same conductive material as the first electrode 22, is disposed on the other surface of the light-emitting unit 23 opposite to the substrate 21, is connected to the light-emitting unit 23, and is not connected to the first electrode 22.
The electrical connection unit 25 has a first extension electrode 251 and a second extension electrode 252 electrically connected to the first electrode 22 and the second electrode 24, respectively, and the first extension electrode 251 and the second extension electrode 252 protrude out of the package layer 3 for electrically connecting with the frequency converter 4. In detail, the first extension electrode 251 is formed from the top surface of the light emitting unit 23, corresponds to the shape of the first electrode 22 and protrudes out of the package layer 3, and the second extension electrode 252 is connected to the second electrode 24 and protrudes out of the package layer 3.
When the low-temperature light-emitting module of the present invention is used, after voltage and current provided from the outside flows through the frequency converter 4 and the electrical connection unit 25, oscillation occurs between the first electrode 22 and the second electrode 24 (positive electrode and negative electrode), and the organic light-emitting material is excited up to 6000 times or more, so that the organic light-emitting material generates redox reaction to emit light. In addition, the low-temperature light-emitting module can emit light but only generate extremely low heat due to the characteristics of the material, and the light-emitting form is surface-shaped light, so that the light is soft, and the direct-view effect is realized, and the low-temperature light-emitting module is not dazzling, so that the low-temperature light-emitting module can be widely applied to different purposes.
It should be noted that, in some embodiments, the substrate 21 and the encapsulation layer 3 may have flexibility at the same time, so that the low temperature light emitting module can be bent and cut at will, and is not limited by the hardware installation space, and has wider applicability.
Referring to fig. 3, it should be noted that, in addition to the structure of the light emitting layer 231 having a single layer as shown in fig. 2, the first electrode 22 and the light emitting unit 23 of the embodiment of the invention may also have a plurality of first electrode layers 221 stacked on each other and a plurality of light emitting layers 231 stacked on each other as shown in fig. 3, and the peripheries of the light emitting layers 231 are respectively connected to the corresponding first electrode layers 221.
In addition, when the light emitting unit 23 has a plurality of light emitting layers 231, a potential difference can be further generated between the first electrode 22 and the second electrode 24, thereby further improving the light emitting efficiency.
The fabrication method of the low temperature light emitting module of the present invention is briefly described as follows.

Taking the first base film 211 as PVC and the second base film 212 as rice paper as an example, first, a piece of rice paper with a smaller area than the PVC film is pasted on the surface of the PVC film, then, a conductive silver adhesive is printed on the surface of the second base film 212 to form a predetermined frame-shaped pattern, and after drying, the first electrode 22 is obtained, and a part of the first electrode 22 overlaps the outer edge of the light-emitting unit 23. Then, the organic light emitting material is coated on the surface of the substrate 21, and the organic light emitting material partially covers the surface of the first electrode 22 for connection, and is dried to form the light emitting layer 231, so as to obtain the light emitting unit 23. Then, a conductive silver paste is applied on the top surface of the light emitting unit 23 (light emitting layer 231) to form a predetermined shape and dried, so as to obtain the second electrode 24. Then, the first extension electrode 251 is connected to the first electrode 22, the second extension electrode 252 is connected to the second electrode 24, and the first extension electrode 251 and the second extension electrode 252 form the electrical connection unit 25, thereby completing the fabrication of the low temperature light emitting device 2.
Finally, the low-temperature light-emitting component 2 is encapsulated by a transparent polymer material to form the encapsulation layer 3, and a portion of each of the first extension electrode 251 and the second extension electrode 252 protrudes out of the encapsulation layer 3 to be electrically connected with the frequency converter 4, so as to obtain the low-temperature light-emitting module shown in fig. 1.
Note that, when the first electrode 22 (first electrode layer 221) and the light-emitting unit 23 (light-emitting layer 231) each have a multilayer structure as shown in fig. 3, the first electrode layer 221 and the light-emitting layer 231 of each layer are formed by being printed and dried separately. Printing and drying to form a first electrode layer 221 of a first layer, and then printing and drying to obtain a first light-emitting layer 231 connected with the first electrode layer 221 of the first layer; then, the first electrode layer 221 of the second layer is formed by printing and drying, and is combined with the first electrode layer 221 of the first layer below, and then the light emitting layer 231 of the second layer is obtained by printing and drying, and the light emitting layer 231 of the second layer is combined with the light emitting layer 231 of the first layer below and the first electrode layer 221 of the second layer, and the steps are repeated in sequence, so that the first electrode layer 221 and the light emitting layer 231 with a multilayer structure can be obtained. Finally, the first extension electrode 251 is connected to the first electrode 22, and the second extension electrode 252 is connected to the second electrode 24.
