The Vietnam Academy of Science and Technology (VAST) has been implementing the project “Local Development and Promotion of LED technologies for Advanced general lighting in Vietnam” (LED Project) which is funded by the Global Environment Facility (GEF), United Nations Development Programme (UNDP) and relevant Vietnamese partners. LED project is now at the  implementation phase. One of the important goals of the project is to support, build capacity and provide training for the staff who are dedicated to working in the fields of research anddevelopment (R&D), design, manufacture, installation and operation of the LED lighting system aswell as to raise  awareness, promote the use of LED among Government units and community andapply LED technologies in the lighting environment. After a series of training activities, the initialresults  have been reaching  the targets of the  project.

Careful preparation, methodical implementation
With the assistance of international and domestic consultants, the LED project management unit (PMU) has built a training program on “Basic and Advanced LED technologies for general lighting”. The experiencedtrainers in the country and abroad have drafted 14 lectures on the core technology and issues related to the design, fabrication, manufacturing and application of LED lamps used for general lighting. Two training courses were held by LED PMU in Hanoi and Ho Chi Minh City for more than 120 technical staff including research and education scientists,construction consultants, lighting design, fabrication and application engineers of LED lighting (indoor and outdoor) in the whole country.
The first training course was held in Hanoi during March 28-30, 2017with the participation of 61 representatives from National Institutes, colleges, lighting manufacturers, construction consultancy companies( Marketingand R&D divisions) and lighting products distributors. As the final part ofof the course, the trainees visitedRang Dong Light Source and Vacuum Flask factory in Hanoi. During the training, in addition to the lectures given by trainers, all trainees werehanded out references and further reading documents (compiled from each presentation) for theirstudying and reference when necessary.
The second training course was held in Ho Chi Minh City for three days from May 23-25, 2017, with the participation of 65 trainees. The structure of this training course is similar to that in Hanoi. Taking the lessons learned  from the training course in Hanoi, PMU had improved the course management by doing daily training assessment. Thismade a positive impact on stimulating mutual interaction between trainers and trainees during lecturing. According to the tentative plan, the trainees would be arranged to visit the LED production line at a local lighting manufacturer, however due to the long distance and time constrain, the visit could not be realized. Instead, based on the proposal of the LED PMU, theDien Quang Lamps Jsc had presented the production lines of the companywitha video clip displayed.

From initial results
According to the training results in Hanoi synthesized by LED PMU, there were 61 trainees in the training course, including those from National Research Institutes, Universities (23%), public lighting companies (39%), construction consultants (15%), lighting manufacturers (sales and R&D departments) and lighting products distributors(23%) (inFigure 1).

Thetraining assessment results given by the participants  shows that: in terms of content, about 85% of participants rated the presentations as “good” or “excellent”. Regarding the possibility of application of training presentation in practical work, It did not meet the expectations of some trainees. (Figure 2)

For the self-assessment of knowledge of trainees after the training, most of the trainees noticed: training course had significantly improved their knowledge (illustrated in Figure 3). Nearly 70% of the trainees said that theyacquired knowledge and improved theirawareness throughvarious topics presented in the training course (Figure 3). In the future to enhance knowledge, trainees need further training.

Besides the aforementioned results, training courses in Hanoi revealed some limitations, which included: lack of interaction between trainers and trainees, the training was arranged in the form of a class that caused difficulty in integrating in the model working group with separate discussion and lack of exercises. Due to the time constrain, the interaction between trainers and traineeswas only one-way communication. The trainees feedbacks showed that as the training assessment was not conducted every training day but only on the last day of the course but not , there were almost no feedbacks from the trainees for the topics presented in previous days
Regarding the training course in Ho Chi Minh City, there were 65 participants coming from public lighting companies (46%), followed by manufacturers of lighting products (40%), the ratio of participants from construction consultancy companies and National Institutes, Universities was similar that accounted for 7%. (Figure 4)

Taking the lessons learned from the training course in Hanoi, to better assess the content of the training, LED PMU and Training organisers haverecommended a series of questions and answers in the form of riddles and quick answers (Q&A) during and after each presentation. Do small exercises at home with prizes for the trainees through the answers to the questions set out each day of thetraining.As a result, over 85% of the trainees have rated the presentations with “good” or “excellent” (Figure 5 below). However beside the success of the overall contents and presentation, the computer application of several presentations only reached (47%) of expectations of the trainees, that has not met the projected target and expectations of trainees (Figure 5. comparison chart of the trainees’ assessmenton training presentations in Ho Chi Minh City).

For the general evaluation on the results of the training, about 70% of the trainees said that they had better knowledge after attending the training, only reaching the average level of requirements. They themselves desire to continue to enhance the knowledge to meet the requirements of the job. So, next training courses (if available) should be appropriately designed for each specific group of participants. (see Figure 6).

In addition to quantitative assessment, reviews of quality wasalso conducted based on the feedback received from the participants. The theme “Technologies for manufacturing of LED drivers” and “Protection against Lightning Impulse and Switching Impulse impact LED lighting system” was rated as most helpful by the trainees from lighting products manufacturers and lighting companies. Other comments related to the improvement of future training courses include: More lessons and practice exercises in the training course; Organize more survey trips to experience the reality of the production line and application of LED technology; Share experience and maintenance of LED technology from real projects; Add the multimedia presentation in trainers at training courses; Time layout of longer training courses, etc.

To the future effectiveness
To evaluate the effect after 3 months of the training course on “The basic and advanced LED technologies for general lighting”, held in Hanoi and Ho Chi Minh City, the LED PMU has sent a questionnaire to find out the effect of the training courses. The figures presented below were drawn from the statistics part of the answers of the trainees in Hanoi training course.
The results showed that the project activities and the knowledge application from the training course can be divided into two main directions. The trainees from Academies,  Universities and research institutions mainly used the knowledge got from the training for their studying and supplementing their teachingcurriculums on lighting. Most of the other trainees was partially applied the knowledge gathered from training into their professional daily work. Some trainees have participated in the project design, installation of LED lighting system at their workplaces . Most of the lectures are applied and used in professional daily work, though it is not really at regular and high level (see figure below);

The trainees applied the trained knowledge in their practical projects at their workplaces and in their working fields. Typical projects: LED lighting use on fishing vessels (trainees from the Hanoi University of Science and Technology); Decorative light system upgrade of some routes and socialized lighting system LED in Son La province (trainees from the Son La Environmental and Urban Construction Company). Replacement of sodium lighting system using LED lighting system on the main streets in the capital of Hanoi (trainees from the Hapulicocompany, Hanoi);Replacement of lamp lines with the power of 250w with Ralaco 70w LED lights, the experiment works in Cau Que, Kim Bang, Ha Nam province (trainees from Ha NamLighting Company); 8 urban lighting projects using the system LEDs in Hue City (trainees from Hue Urban Lighting company). Design, installation of the LED system for the project “Installation of the lighting system for 6 communes in Son Tay town”; and “Decorative indoor and outdoor LED lighting system for old castle of Son Tay” (trainees from Son Tay Environmental and Urban Construction Company), ….

The above mentioned results showed that the majority of the trainees, after attending the training course could grasp the necessary knowledge and well applied in their work. Although the field of application of each participant is different, depending on their working environment, the application results seemed to bring advantages. This is also one of the successes of the training course on “Basic and Advanced LED technologies  for general lighting” organized by the “Development and the promotion of LED technology for general lighting in Vietnam” PMU in collaboration with local and international experts over time.
Results of the two training courses showed the impact through a dual effect:  about 90% of the trainees in both courses have enhanced their capability, knowledge about LED technology and the application in practice has increased after the  training. The results also showed the training, knowledge and competencies of traineesonly reached average level. The level of training  applicationis also lower than the theoretical knowledge. Currently, LED technology is developing rapidly withnew knowledge and products constantly updated. So, most of the participants desire to betrained and updated with LED technology and technical knowledge which are really essential and continuous for the staff working in the field of lighting in Vietnam.
