As the drive current increases, the white LED color temperature is increased as the current increases. Proposed sale of white LED products, providing customers with complete product specifications and instructions, provide good after-sales technical services to help customers achieve anti-static control to prevent abnormal electrical products, and guide customers to avoid the safe use of products, product parameters and specifications does not match the book rather unnecessary customer complaints.
Profile: Lin Kai this, male, Putian City, Fujian, who studied under Professor Guo Zhenning, optical master. Research interests include high-power white LED packaging, LED applications, project development and design.
Content: First, strict testing station LED solid crystal raw materials 1. Grain: mainly for the pad contamination,LED sign, grain damage,business neon sign, grain cutting sizes, grain cutting tilt. Preventive measures: strict control of incoming inspection, found the problem requires suppliers to improve. 2. Stents: mainly for the deviation �� size and C size is too large, frame rust color, frame deformation.
Incoming material are the supplier, it should inform the suppliers to improve and strictly control the feed. 3. Silver plastic: mainly for the poor degree of silver adhesive, used for more than, storage conditions and thawing does not conform with the actual conditions and so on. For silver viscosity, general assessment by the project will not have too much production, but not to say that the kind of silver plastic is the best,menu board, if there are bad happens, we know that will work for further assessment.
Other period of use, storage conditions, thawing conditions are artificially controlled, as long as strict accordance with SOP operations, generally will not have too many problems. Second, reduce the negative human factors 1. Operators of illegal operations: for example, do not wear gloves, silver plastic removed from the refrigerator after thawing has not been directly on-line, and the workers do not follow the SOP work, or unskilled plant operators Dengjun will affect the solid crystal quality.
Preventive measures: the foreman to strengthen management, operator by SOP operation, quality assurance personnel to strengthen audit, on the machine to strengthen education and training unskilled workers, there is no formal induction appointment cards are not allowed. 2. Shunting improper maintenance personnel: Strategy is to enhance the technology? X level. For example, take crystal height, solid crystal height, thimble height, some delay time setting, the motor parameters, table settings and other parameters, according to the standard required to adjust to the best.
Third,LED outdoor sign, ensure the machine will not be the main aspects of the performance of non-performing machine a number of spare parts for the machine or mechanical structure, knowledge systems, caused by the poor quality of the solid crystal. Must ensure that the function of the machine is normal. Fourth, the implementation of the correct method of adjusting machine 1. Not a good spot: Strategies ---- re-proofing spot, to ensure three points line.
