"From the LED lamp beads package, the first light is relatively simple. Packaging companies are generally based on the cost and mass production point of view, many consider the material and structure to fully extract the light bar shaped LED, and improve efficiency. Another is to be done in line with the light color of our requirements, including color temperature control, color temperature uniformity control space. The real light, have to rely on secondary optical design. "However, companies in the process of design of the optical system , often using ism install bar shaped LED, slightly modified, or directly using the vendor's solution. The biggest problem facing the industry is the lack of professional personnel, and LED optical design requires a higher supply of bar shaped LED, enterprises generally lack of theoretical guidance, companies can be rare rational system design LED light system. In some projects, it is relying on the rational application of project management bar shaped LED, in order to promote the project completed on time and with high quality. LED display more complex engineering, project management is essential. Project management is the use of specialized knowledge, skills, tools and methodologies in project activities, the project to achieve or exceed stakeholder needs and expectations. Which means that the stakeholders involved in the project and everyone affected by the project activity. Project Time Management includes the timely completion of the process so that the project must be implemented. The main process includes activity definition, sorting activities, activity resource estimating, activity duration estimates, develop schedules and schedule control. Events definition involves identifying specific project team members and stakeholders to complete the project deliverables man must be completed; the program involves estimating Events resource estimate completed; activity sequencing involves determining the dependencies between project activities and the formation of the corresponding file the type and number of required resources; activity duration estimating the number of units involved in the estimated hours to complete specific activities needed; to develop a schedule involves analyzing the sequence of activities, activity duration and resource requirements, and schedule constraints, and thus to develop a project schedule ; schedule control involves the control and management of the project schedule changes.
