A corrente de pico se refere à corrente de pico ou corrente de sobrecarga que é muito maior do que a corrente de estado estacionário gerada no momento em que a alimentação é ligada ou quando o circuito está anormal.
No projeto eletrônico, surto se refere principalmente ao forte pulso gerado no momento em que a fonte de alimentação (principalmente se refere apenas à fonte de alimentação) é ligada.… Read More
Lighting fixtures that use AC power directly on the lamp head require a simple AC/DC constant current source driver IC with a simple application circuit and low cost.
Most of the driver ICs currently in use are flyback constant-current driver solutions converted from switching power supplies, using the principle of isolation and step-down. Divided into two types of applications: primary-side feedback control and secondary-side feedback control.… Read More
По составу пускатель можно разделить на: стеклянную колбу, заполненную неоновым газом, статический контактный элемент и подвижный контактный элемент. Контактная деталь биметаллическая.
Принцип работы такой: при включении переключателя напряжение питания сразу же добавляется на два полюса стартера через балласт и нить накала лампы. Напряжение 220 В немедленно ионизирует инертный газ стартера и дает тлеющий разряд.
Тепло этого процесса заставляет биметаллическую деталь расширяться.… Read More
Science and technology are advancing with each passing day, and science and technology create a new life for mankind. In recent years, the global human consensus: the future of industries related to green, environmental protection and energy saving is bright and brilliant. The LED lighting industry is the first to bear the brunt, and it will show infinite vitality and an infinite market.… Read More
La iluminación comercial también se denomina iluminación comercial. La diferencia obvia entre esta y la iluminación del hogar es que el sitio de aplicación es diferente, por lo que existen diferencias obvias en los requisitos, el diseño y las características del producto. La iluminación comercial tiene definiciones científicas y requisitos para la iluminancia, la temperatura del color y la reproducción del color de las fuentes de luz utilizadas en entornos comerciales específicos.… Read More
This article introduces a variety of driving methods for high-power and high-brightness LEDs. The following tasks need to be completed to build an LED-based system:
1Lux si riferisce all’illuminamento in cui 1L di flusso luminoso è distribuito uniformemente su un’area di 1 metro quadrato. Generalmente, gli illuminatori attivi utilizzano unità di intensità luminosa CD a candela, come lampade ad incandescenza, LED, ecc.; oggetti riflettenti o trasmissivi utilizzano unità di flusso luminoso lumen L, come proiettori LCD, ecc.; e unità di illuminamento Lux, generalmente utilizzata in fotografia e in altri campi.… Read More
At present, in the general LED lighting market, there is a distinction between non-isolated design and isolated drive power. Non-isolated design is limited to double insulation products, such as replacement products for light bulbs. The LED and the entire product are integrated and sealed in non-conductive plastic. Therefore, the end user does not have any risk of electric shock.… Read More
The most popular word today is wisdom or intelligence.
Smart home is to connect various devices in the home together through the Internet of Things technology for orderly control. It sounds simple, but it is actually very complicated. Because this involves integrated wiring technology, network communication technology. Specifically, there are two points that must be emphasized:
Le rendement lumineux élevé des lampes fluorescentes LED est un indicateur très important, qui reflète directement la qualité des tubes LED. Comment atteindre le meilleur rapport qualité/prix ?
2835 perles de lampe simple ont 0,12W 14-16LM (la taille de la puce est de 10*23nm) et 0,2W 22-24LM (la taille de la puce est de 10*30nm), qui conviennent tous deux à la lumière du jour.… Read More
