At present, there are many kinds of energy-saving lamps in the market, and LED energy-saving lamps are more advanced and more environmentally friendly. The data shows that led energy-saving lamps save 80% power than incandescent lamps and 50% power than fluorescent lamps. With the advantages of energy saving and environmental protection, LED lamp has become the main trend in the development of lamp industry.… Read More
LED grow light je umělý světelný zdroj, který využívá LED (light emitting diode) jako světelné těleso ke splnění světelných podmínek požadovaných pro fotosyntézu rostlin. Klasifikováno podle typu patří do třetí generace doplňkových světelných zdrojů pro rostliny.
V prostředí bez denního světla může tato lampa fungovat jako denní světlo, což umožňuje rostlinám růst a vyvíjet se normálně nebo lépe.
Tento druh lampy má silné kořeny, podporuje, reguluje dobu květu a barvu květu, podporuje zrání a zbarvení ovoce a zvyšuje chuť a kvalitu.… Read More
The basic elements of lighting design mainly include:
The illuminance standard of industrial buildings is determined according to the IEC “Lighting Design Standard for Industrial Enterprises” TJ34-79. The illuminance of civil buildings should be selected according to the requirements of use and in accordance with the “Technical Regulations for Electrical Design of Buildings”.
For general lighting in places where lamps are hung high (such as tall factories), high-pressure sodium lamps, self-ballasted high-pressure fluorescent lamps or high-efficiency LED lamps (luminous efficiency greater than 120lm/W) should be used.… Read More

Color Rendering Index (CRI)
Refers to the appearance of a target object under a light source compared with the original color under a reference light source (such as daylight), how realistic the performance is the same as the original color
Contrast sensitivity (contrastsensitivity)
The ability to detect differences in brightness, if stated qualitatively, it is equal to the reciprocal of the contrast limit
Cutoff angle ofa luminaire
Measured from the lowest point, the angle between the first ray of naked light that cannot be seen by the human eye and the vertical line
Diffuse reflection
Refers to the process in which the incident light beam is reflected back within a certain angle range
Diffused lighting
Refers to an illumination method in which the incident light does not mainly come from a single special direction
Diffuser
Refers to a device that can reflect or scatter the light emitted by a light source, usually mainly through diffusion
Direct glare
Glare caused by extremely high brightness, insufficient light source shielding, or high-brightness reflection in the field of view.… Read More
Como uma infraestrutura de serviço de longo prazo, a estação ferroviária é a fundação centenária da cidade. Com o vigoroso desenvolvimento da iluminação comercial e interna nos últimos 50 anos, a iluminação da estação ferroviária não só atendeu às necessidades simples de iluminação geral para passageiros que compram passagens, esperando trens e entrando e saindo de estações, mas também acrescentou mais fatores humanos e combinado com as funções das estações ferroviárias.… Read More
The life of the light source is also called the life of the light source. The life of an electric light source is usually expressed in terms of effective life and average life.
LED на английском языке означает (светоизлучающий диод), светодиодная лампа – это аббревиатура LED от популярного названия светоизлучающий диод.
Принцип люминесценции
Напряжение на клеммах PN-перехода составляет определенный потенциальный барьер. Когда прикладывается прямое напряжение смещения, потенциальный барьер падает, и основные носители в областях P и N диффундируют друг к другу. Поскольку подвижность электронов намного больше, чем подвижность дырок, большое количество электронов будет диффундировать в P-область, что представляет собой инжекцию неосновных носителей в P-область.… Read More
The operating room is the most typical clean space in the hospital. It is an area where doctors perform fine work. It requires high lighting and the standard requires more than 750lx. It is recommended to carry out the design according to 1000lx, and at the same time improve the color rendering as much as possible to improve the medical staff’s focus on the disease.… Read More
