What is the main work of laboratory led optical / led lamp testing engineers? Is it harmful to your health? _ Baidu.
ExceptThe aging workshop and testing basically do no harm to the eyes.The possibility ofHowever, there are protective measures in both stations, so there is no need to worry.
Led lights are harmless to the human body. When electrons recombine with holes, they can emit visible light, so they can be used to make light-emitting diodes. Used as an indicator light in circuits and instruments, or as a text or digital display. Gallium arsenide diodes glow red, gallium phosphide diodes glow green, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light.
LED electronic engineers mainly develop and design LED lamp products, such as designing LED lamp circuits, drawing circuit boards, and doing various performance tests, that is, the work of the whole project has to be done.
I don’t think there is much problem with plug-ins and assembly links. Mainly in the welding process. It is usually soldered with tin. Tin used in welding is often impure and contains some lead. Some directly use lead-containing solder. Lead is a heavy metal and is harmful to human body. Therefore, attention should be paid to protection when welding.
LED light radiates to the body, such as blue light. Blue-light-rich LED outdoor lights may reduce the secretion of the hormone melatonin. Secreting melatonin at night helps balance reproduction, thyroid and adrenaline, and regulates the body’s circadian rhythm.
Introduction of Light Source and Lighting engineer
The major of light source and lighting is a marginal cross-discipline that brings light to human beings. it plays a special and important role in all fields of national economy, such as industrial and agricultural production, scientific research, transportation, national defense, medical and health, business and office, culture and entertainment, daily life and so on.
Lighting designer, light source and lighting engineer. Lighting designer: this card is divided into three levels: assistant lighting designer, intermediate lighting designer and senior lighting designer. Light source and lighting engineer: this certificate is divided into three levels: assistant light source and lighting engineer, light source and lighting engineer.
Professional positions in light source and lighting include: lighting designer, foreign trade business manager, electronic engineer, sales engineer, led lighting senior electronic engineer, light source and lighting engineering, sales manager, led structure engineer, light source and lighting engineer, sales representative and so on.
Light source and lighting professional employment prospect is quite good, lighting designer, foreign trade business manager, electronic engineer, sales engineer, led lighting senior electronic engineer, light source and lighting engineering, sales manager, led structure engineer, light source and lighting engineer, sales representative, etc.
What is the job responsibility of a quality engineer as a finished LED lamp?
At least 3 years experience in lamp circuit design. Experience in circuit design of LED lamps is preferred.Can work with structural engineer to carry out lamps and lanterns independentlyThe circuit design of. Know the common test tools and test verification methods of lamps and lanterns.
Quality engineers are implementing the quality management system in some areas.In the organization, the staff responsible for the quality assurance functions required by the quality management system standards.
Professionals who can closely follow the changes of lighting market demand and combine their own design concepts to design and develop lighting products.
The supervisor is more responsible than the engineer.Responsibilities of supervisorOrganizational management of the quality management department to establish, improve and improve the structure of the quality management department, establish a quality management team with team spirit, and clarify the responsibilities of each job.
Under the leadership of the production manager, carry out all kinds of production technical work. Assist process supervisor to prepare technical documents such as product process plan, product process card, post operation method, etc. Assist the process and technical supervisor to compile the consumption quota of raw and auxiliary materials, packaging materials, intermediate reserve, etc., and check the implementation of the workshop.
What is the prospect of being a lamp engineer now?
Optical direction, small demand, high threshold, good prospects, generally engaged in optical design work in large companies, such as optical lens design, optical device design (optical communication), lighting optical design and so on.
The living room should choose a dignified, bright chandelier or ceiling lamp. If the room is taller, it is appropriate to use incandescent chandelier or a larger round chandelier, so that the living room appears transparent, but it is not appropriate to use all downward light distribution chandelier, but should also make the upper space have a certain brightness, in order to reduce the brightness difference between the upper and lower space.
Question 7: what do undergraduates majoring in optoelectronic information engineering do after graduation? optoelectronic information technology is widely used in various industries of national economy and national defense construction. The prospect is very good. The recommended place of employment is Wuhan. Isn’t there a Chinese Optical Valley? There are many optoelectronic enterprises in Beijing, Shanghai and Guangdong, which are also good. There is a wide range of employment.
