Når du ser at LED-lyset på brettet produserer en farge som endrer seg over tid, vet du hvordan det oppnås?
Partnere som har utført MCU-program eller FPGA-logikkprogrammering bør vite (det er mange artikler om PWM som også er spesifikt introdusert), det oppnås ved å justere lysstyrken til de tre fargene R, G og B på følgende måte.… Read More
Color gamut determines the color richness of a display. As we all know, CRT displays and liquid crystal displays are based on three-primary color imaging, and the colors presented by the display are a partial collection of the three primary colors, but there is no way to express all the colors of visible light. The color gamut value represents the range of colors that the monitor can present.… Read More
Какой световой поток необходим каждому растению?
Когда мы выращиваем растения в собственном дворе, в палатке для выращивания или в большом помещении для выращивания, будь то цветы, помидоры, салат или каннабис, нам нужны некоторые необходимые условия. Достаточное количество воды, воздуха и удобрений являются необходимыми элементами для роста сельскохозяйственных культур. Другой момент заключается в том, что все зависит от солнца, чтобы расти, а правильное освещение повысит урожайность.… Read More
Adopting new technology to achieve true ultra-long life low voltage aluminum electrolytic capacitors
If low-voltage electrolytic capacitors want to achieve 10,000 hours at a temperature of 105 °C, from the perspective of product quality control and product consistency, electrolytes with high water content should be avoided. Turn to other high-tech.… Read More
Mezzo secolo fa, se la tua lampadina si rompeva, l’unica alternativa praticabile erano le lampadine a incandescenza. A quel tempo, le lampade a incandescenza erano vendute ovunque, potevano essere sostituite rapidamente ed erano molto economiche.
Tuttavia, dagli anni ’90, è stato difficile trovare lampadine a incandescenza di qualsiasi forma.
Quindi, cosa ha causato l’aumento e la caduta delle lampadine a incandescenza come le montagne russe?… Read More
LED is an electric light source with an extremely long life, which can reach 100,000 hours (about 140 months, or 11 and a half years of continuous use!). The life of general fluorescent lamps is generally not more than 10,000 hours. Another feature of LED is high luminous efficiency. The luminous efficiency of practical high-power LEDs has exceeded that of T8 fluorescent tubes several times.… Read More
Licht emittierende Diode (LED) ist die neueste Generation der Lichttechnik und eine revolutionäre Erfindung im Bereich der Beleuchtung. Seine Vorteile liegen auf der Hand – bis zu 200 lm/W Lichtausbeute, Langlebigkeit und bis zu 50000 Stunden Lebensdauer. Die Festkörper-Halbleiter-Lichtemissionstechnologie von LEDs macht ihre Lebensdauer mehr als zehnmal länger als die von Glüh- oder Leuchtstofflampen. Dadurch haben LED-Lampen viele Vorteile, an die Leuchtstofflampen, HPS- oder MH-Lampen nicht heranreichen.… Read More
The IEC organization proposes to use the maintenance rate to describe the failure rate, life, life expectancy, etc.
EPA (United States Environmental Protection Agency) announced: Energy Star Lamp V1.0 technical specification is “technically neutral”, which stipulates that the life of matching lamps is 10,000 hours, that is, the rated lumen maintenance rate life, and integrated LED lamps require 15,000 to 25,000 hours.… Read More
Après plus d’un siècle de développement dans l’industrie mondiale de l’éclairage, aujourd’hui, les lampes les plus largement utilisées ne sont que les lampes fluorescentes compactes (CFL) et les lampes à diodes électroluminescentes (DEL).
Les lampes CFL et les lampes LED sont certainement plus efficaces que les lampes à incandescence, mais la façon dont elles émettent de la lumière est encore différente.… Read More
The light efficiency of semiconductor lighting, or energy efficiency, is an important indicator of energy-saving effect. At present, the industrialization level of light efficiency of LED devices can reach 120-200lm/W, and the total energy efficiency of lighting lamps can be greater than 150lm/W.
This is still not high, the energy-saving effect is not obvious, and there is still a long way to go from the theoretical value of 250lm/W of luminous efficiency of semiconductor devices.… Read More
