    Triac dimming and 0/1-10V LED dimming

    Triac dimming This method was developed in the 1970s and has been the most commonly used dimming technique for decades. It does this by changing the waveform turns on, thereby changing the amount of current or power flowing to the light. This common dimming method uses thyristor components to control the brightness of the light, and adjusts the light by controlling the on and off of the current. When the thyristor device is forward biased, current can pass through and the brightness of the light increases. When the thyristor device is reverse biased, the current cannot pass through and the brightness of the light decreases.

    What is the difference between DALI DT6 and DALI DT8?

    DALI (Digital Addressable Lighting Interface) is a protocol for digital lighting control that allows reliable, scalable and flexible lighting networks to be connected and configured. DALI is currently the most widely used digital protocol. When talking about DALI control, in addition to DALI-2, DALI DT6 and DALI DT8 are often mentioned. But what do these definitions mean? What are their differences? DALI Device Type The DALI protocol is supported and promoted by the DALI Alliance (DiiA), a group of global lighting companies established to develop the market for DALI-based control solutions. The protocol was originally developed to allow digital control, configuration and interrogation of fluorescent lamp ballasts to replace simple one-way, broadcast-like 0/1-10V dimming applications. In the DALI protocol, basic broadcast options are available, and through simple configuration, each DALI device can be assigned an individual address, allowing digital control of individual devices. DALI is a two-way communication protocol. The DALI protocol has been expanded many times since its inception and now makes it possible to determine whether a light fixture is working properly and its luminous intensity level, with each new device being assigned a new unique number. The device type (DT) numbe

    Why is power factor important when measuring efficiency?

    Basics of Power Factor and Efficiency Engineers working with external power supplies (EPS) are no stranger to efficiency measurements. However, since their applications typically operate on DC power supplies, common mistakes can be made when measuring power on the AC side of the power supply. These common pitfalls include incorrectly measuring or completely ignoring power factor when calculating power input power, resulting in incorrect efficiency measurements. Let's review the basics of power factor and efficiency and then provide guidance on how to include power factor when measuring AC. DC power efficiency. Power Factor and Efficiency, a Review Efficiency (η) is the ratio of output power to input power: Equation 1: Efficiency In

    The main classification of power supply

    . Classification of LED driver power supply 1. According to the driving mode, it is divided into constant current type and constant voltage led driver 1) Constant current type: The characteristic of the constant current type circuit is that the output current is constant, and the output voltage changes with the change of the load resistance. The constant current type power supply to drive the LED is an ideal solution and is not afraid of the load short circuit, and the LED brightness is consistent. Disadvantages: The cost is expensive, the load is completely open-circuited, and the number of LEDs should not be too many, because the power supply has a maximum withstand current and voltage. 2) Constant voltage type: The characteristic of constant voltage driving circuit is that the output voltage is constant, the output current changes with the change of the load resistance, and the voltage will not be very high. Disadvantages: It is forbidden to completely short-circuit the load, and voltage fluctuations will affect the brightness of the LED. 2. According t

    What are the advantages of dimming power supply over ordinary LED power supply?

    More than a hundred years ago, Edison invented the electric light, which brightened the human world. But with the continuous progress and development of lighting equipment, pure light can no longer meet people's needs, especially in hotel engineering lighting, smart home lighting, commercial lighting, outdoor lighting and so on. Different lighting environments can create different atmospheres and achieve energy saving and environmental protection effects. Therefore, the dimming power supply has brought great benefits to people's life. 1. Dimming the power switch is a gradual process of light change Usually, in areas without a dimming system, when the lights are turned on, they suddenly become fully bright; when they are turned off, they suddenly become completely dark, and the overall lighting effect is very hard; while in areas equipped with dimming systems, when the lights are turned on, the lights gradually turn from dark to bright ; When the light is turned off, the light will gradually dim from bright to avoid sudden changes in light brightness from irritating the eyes, which can not only protect the eyes, but also bring us a comfortable visual experience. 2. Dimming to achieve energy saving Lights are artificial lighting that provide enough light at night or in situations where natural light is insufficient. But lights consume electricity, and turning off lights when not needed saves energy. And in some periods of time to supplement the

    What is a UL Listed Adapter

    A UL listed adapter is an AC adaptor that meets the safety standards outlined by the Underwriters Laboratories (UL). This is an organization that provides safety power supply certification for a wide variety of products include electrical devices, electronic equipment, building products, medical equipment, processed foods, water heaters and fire protection products. These universal ac to dc adapter are subjected to stringent testing and evaluation to ensure they meet UL`s criteria for performance and safety. With a UL/cUL listed adapter, you can be sure that the universal plug in class 2 transformer has been thoroughly evaluated and meets industry standards for electrical safety. These class 2 power transformer provide an extra layer of safety for customers who rely on electrical products for their everyday needs. When class 2 power supply adapter is UL/cUL Listed, that means that the UL has tested the device, and it meets their requirements for safety (fire or shock hazard). Because of this it is highly recommended that all of your electrical products carry the UL seal so that you can ensure the customers safety and satisfaction with your class 2 power supply 120vac 60hz.
