As organization, 3elamp goals are:
With customer as the compass that directs our decisions, we are always pursuing more effective business processes and the Quality Control is in the centre of all the chain that supports value creation for customers and stakeholders. We can summarize the Product Quality Assurance processes as follows:
The need for start designing a new lamp or luminarie can come from a customer request, an improvement on the technology that can provide better products and/or costs or because our marketing research detects a lack on our portfolio.
To design a new lamp or luminarie is a team task involving a great number of technician and professionals; much more people than can be thought from outside the industry.
Once the project for a new product has been approved by the Board (and this means to allocate resources but also to define a target cost), the Technical Development Department makes a preliminary design and starts to work together with the partners that has been identified as the more accurate for the project: Light Source Suppliers; Mechanical Engineering Companies or Housing suppliers; optical, PCB and Driver manufacturers; and any other else that can be involved as per the preliminary definition.
When the new design is conceptually clear we pass to the prototyping phase. In this stage everybody do his part and we get the first physical prototype that will be tested for the general parameters of performance.
After final adjustments are done we produce a preliminary series and send some pieces to an external laboratory (usually we work with western or CNAS listed labs) to pass the standard common tests as LVD and EMC. With the rest of the series we test the performance under heat or humidity conditions (depending on the kind of lamps) and/or luminosity performance (with IES files generation).
Knowing that the management of the heat is a must for a LED long- life, we carry high temperature performance tests to ensure that our lamps and luminaries will function perfectly under regular ambience conditions.
If everything is ok we can start the regular production an include the new product in our portfolio.
Selecting the right suppliers is key for the final quality. For sure we always can find a cheaper supplier but price only becomes important when the quality is determined. This makes us to establish long time relation with our suppliers till they become our valuable partners.
When a new Production Order is launched, our suppliers receive our Purchasing Order with part number and detailed technical data of what we need to receive. Later, on the reception, everything will be checked by our Quality Department and specially:
In our own facilities the quality control is introduced in each step of the process.
We know that long-term success requires daily improvements. So we are an ISO 9001:2008 certified company that produces under well-defined procedures and apply the kaizen principles in order to ensure that every day the production will be finished on time and with better quality.
3elamp is committed to providing environmentally friendly products to the lighting market. We will not intentionally add to our products any restricted materials as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE).
To check the RoHS compliance our Quality Department uses a Skyray Tester Machine in our own facilities where each received component pass a test with statiscally significant samples.
The light sources pass a statiscally significant sample test on the spectroscopy system and its performance and homogeneity is compared with our product specs and the customer requirements.
A statiscally significant sample test is conducted with the drivers in order to ensure the homogeneity of its performance and its specs compliance.
We use top quality external suppliers for reflow soldering the SMD on the PCB because they can always use the most modern machines and really skilled operators. We consider this a task for a specialist, so we bring our PCB and our SMD to his facilities, and go back to our factory when the job is done.
We check each PCB on the same soldering supplier before take them back.
We are combining several components and we want to be sure that our customers will receive reliable products. Is there a better way to have the lights burning to check if everything is ok? Maybe there is, but we still entrust in this old tradition.
Before shipping, our lamps and luminaries will be lighting for at least 36h. Only after this aging period will be allowed to be packaged and shipped.
Once the lamps or the luminaires are finished we test its overall performance. Before the shipment is send out we check the quality of the light (lumen emission, Ra, homogeneity, etc.) and the electronic parameters (system consumption, Power Factor, etc.).
Everybody can imitate what we do. But will not be easy to do as we do.
