Electroluminescence in the solid is a phenomenon known for many years and studied in depth. Among the many types of LEDs known, one has opened a completely new field of technology: electroluminescent p-n junction injection. The emission of light of a p-n junction was observed for the first time in 1923 Lossew. Later (around 1962) found that relatively high levels can be obtained from the p-n junction light energy of gallium arsenide (GaAs). LEDs can be used for road signs; the name for this is led signs. From 1962, a major international program was aimed at producing a light-emitting electroluminescent device with advantages:
-currents and low voltage supply;
accuracy of determination of area-specific lighting lithographic processes involved.
-speed switching that device must be ordered.

The reusable bags complete the objectives of the environmentalists in reducing the consumption of the plastics. The industry of reusable bags forward the causes against plastic pollution. This problem creates new problems in the societies. One of the major reasons of this problem is caused by the physical properties of the traditional plastic bags. Decomposition is slow in these materials. The market of plastics motivates the people to assist in the available programs and projects of the eco groups. The environment needs the appropriate solutions and services to support their main goals. The industry also creates new markets based on recycling and innovations. In this challenging generation, environmental problems are rampant and unavoidable. Major changes can only be achieved after the success of the green industries. The inspiration from the reusable bags industry still needs to penetrate the societies. Families and individuals must determine their own actions with respect to the disposal problems and solutions.
