| We chose Modular LED Lamp project, because it sounded interesting (more energy effective lighting) and we had two electrical engineer students in our group. Although, they had knowledge about electricity, there have been still appearing some complications. | We chose Modular LED Lamp project, because it sounded interesting (energy effective lighting) and we had two electrical engineer students in our group.

| First of all, to hand in list of materials, it was necessary to present correct schematics for the LED lamp and remote control. As we didn’t have much experience with LED lamp specialities, completion of schematics and material list was delayed. This led us to the situation that we got materials too late. We had 2 days to assembly product and make the tests. Sadly some problems occurred and prototype didn’t work. . We had to forget about the remote controll and replace it with a single switch button in order to be able to change the colors and different sequences. | First of all, to hand in list of materials, it was necessary to present correct schematics for the LED lamp and remote control. As we didn’t have much experience with LED lamp specialities, completion of schematics and material list was delayed. This led us to the situation that we got materials too late. We had 2 days to assembly product and make the tests. Sadly some problems occurred and prototype didn’t work. Reason was wrong PCB. To solve this situation and present working prototype, we changed the electrical schematics and PCB into easier ones. This change allowed us to see improvements. In current state LED Lamp is able to change colours, there are several colour variations which are described in paragraph 7.5. For changing colours there is button in the lamp, remote control is not used in that kind of solution. Lamp also fits to the E27 socket. |
| In order to have unique product, we made a special design for the light bulb. We created 3D drawings with software called Solid Edge. Our light bulb is inspired by nature and resemble a bit wood branch. Drawings were converted to the suitable version to use a 3D printing option that was by school. The bulb prototype was made of plastic. Also there was made a package. As we are focusing on business clients, it was not necessary to pay so much attention to the packaging. Our package is made of 2 colour cardboard (black and orange) and on the package surfaces are presented all important labels. | In order to have unique product, we made a special design for the light bulb.

| From the beginning we have tried to create the most effective team, therefore we used Project management tools like tasks distribution, found several solutions for communication and we set deadlines to ourselves. In our work we want to be precise an always give our best. It is important to hand in deliverables in time, unfortunately there was delay concerning some materials. While we were not able to build prototype we were focused on report, web-page, user manual, packaging, poster, video and bulb design. These parts of deliverables have progressed successfully and what is important, in time. We got materials two days before final assessment, this situation forced us to work faster and more effective. As much as we tried prototype production was not successful, lamp functions did not work. Reason of that problem was PCB which was wrong and also programming. Lack of time didn’t let us to correct these major mistakes. | From the beginning we have tried to create the most effective team, therefore we used Project management tools like tasks distribution, found several solutions for communication and we set deadlines to ourselves.

As much as we tried prototype production was not successful, lamp functions did not work. Reason of that problem was PCB which was wrong. Lack of time didn’t let us correct major mistakes, but to solve this problem we drawn new electrical scheme and changed PCB into easy one in order to achieve at least working lamp. This change allowed us to see results. In current state LED Lamp changes colours, but with no help of remote control, there is a button in the lamp which allows changing the colour modes. Also lamp fits to the E27 socket, but other initially set goals need to be improved in future. |

| During all the semester we learned a lot about team work and studied lighting specifications in every field. We tried to create the best product we could considering objectives and advice given. | During all the semester we learned a lot about team work and studied lighting specifications in every field.

| This experience gave us definitely advantage in future life. We were able to practice English, we studied lighting specifications, learned sustainability and marketing issues as well as improved our communication and cooperation skills. | This experience gave us definitely advantage in future life.

As much as we tried prototype production was not successful, lamp functions did not work. Reason of that problem was PCB which was wrong and also programming. Lack of time didn’t let us to correct these major mistakes. | As prototype of Modular LED Lamp was not fully successful in testing, new prototype needs to be developed. New PCB and programming improvements has to be done. Nowadays, people want to control everything from their computer and phone. It means an instant access to their devices. Therefore, development considering the remote control could be an option. Instead of using infrared communication between lamp and remote control, we could use Bluetooth or Wi-Fi connection between device and Web application or also design a mobile application for that purpose. |
| | We would like to decrease the size of the lamp. It is necessary to reduce PCB boards and use, for example, other movement detecting sensor in order to achieve smaller bulb dimensions. There are some opportunities for light bulb design development as well. For example, it would be better if there is possibility to move/turn movement detecting sensor. As ultrasound sensor was so big it was very difficult to place it the way that it would move. What is more, different material could be considered, because already used material is sensitive to heat and in high temperatures it could melt. In future design we can use a flexible material. |
