What is a Class 2 power supply?

LED Power Supplysfyh
Generally speaking, class 2 standard is for North American market using, class II is for European market using. Both of them are important standard for safety of the power supply and the user. Here I would like to make a brief introduction for the driver power supply with class 2 standard. The class 2 here refers to the power performance and wiring requirements. When you find a power supply with a label marked class 2, then it means that it must meet the standards laid out by The National Electric Code. To avoid risk of shock or fire, the wiring and power…

Eight tips to improve the efficiency of LED power supply

LED Power Supplysfyh
1. The main current loop PCB should be as short as possible.   LAYPCB experience, and layout, this is nothing, the quick way is to look at the works of big factories.   2. Optimize the design of 300w LED transformer parameters to reduce eddy current loss caused by ringing.   This is more difficult. First, you must master the basic knowledge of electromagnetics and design a reasonable transformer. The most important thing is patience. Even if you think of improving the efficiency by 0.5%, you must try.   3. Reasonably select switching devices.   This is the balance between cost and performance. What kind of…

How much do you know about DALI dimming?

LED Power Supplysfyh
DALI dimming products are developed and designed based on the DALI protocol, DALI “digital lighting control international standard, the full name is: digital addressable interface standard, DALI protocol is an open asynchronous serial digital communication protocol. DALI protocol is dedicated to lighting control protocol, only used in lighting systems. The open standard of DALI protocol makes DALI dimming power supply very compatible. As long as the company that produces LED dimming power supplies joins the DALI Association, they have all DALI According to the agreement, power products that meet all DALI standards can be developed and produced.    The above…

What size led driver do I need?

LED Power Supplysfyh
In some cases, one of the biggiest factor to choose the best led driver is the size.When your LEDs are relative small and need the compact size of the led driver,  the 12v 6w led driver is small and suitable for your project. When your project are looking for the medium size, our 24vdc 80w led driver 190*48*34mm  would be your first demand of your thoughts. Also, we also had some big wats like 12v 200 watt 300watt led power supply, which could meet some of your big watts led strip lighting project. That would be helpful and possible for…

What is the influence of ripple in a LED driver?

LED Power Supplysfyh
The ripple processing will directly affects the working performance of the electrical products that the constant current or constant voltage LED driver carries. For different electronic products, the processing requirements for ripple are different. There is no standard for the range, but the smaller the processing, the better. For the consumption of LED lights, there will be some impact. If using poor quality power supply, this will accelerate the light decay and heat generation of the LED light, it is necessary to minimize and control the ripple. Otherwise, the LED light will fade too fast and will become less and…

What are the main advantages and Benefits of LED street lights?

LED Lightssfyh
What are the main Advantages and Benefits of LED street lights? LED street lamps refer to street lamps made of LED lamps, which have the advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response speed, and high color rendering index. They are of great significance to urban energy-saving lighting. The LED is small in size and light in weight. It is packaged with epoxy resin, which not only protects the internal chip, but also has the ability to condense and transmit light, and its service life is mostly between 5,000 and 100,000 hours. The Smart LED…

​The Effect of Led Plant Grow Lights on the Growth of Seedlings

LED Lightssfyh
The Effect of Led Plant Grow Lights on the Growth of Seedlings The Grow Plant light quality is modulated by the accurate spectrum principle of the new light source of the LED plant growth lamp, and the tomatoes in the facility are regularly supplemented with light, and the effect of different light quality in the LED plant supplement light on the growth of vegetable seedlings is studied. The actual results showed that LED red light and red blue light had significant effects on tomato seedling growth indicators, and the stem thickness, fresh dry weight and strong seedling index were significantly…

What Is Led Flood Light?

LED Lightssfyh
What Is Outdoor Led Stadium Flood Light? Outdoor Led Stadium Flood Lights are lamps that specify that the illuminance on the illuminated surface is higher than that of the surrounding environment. Also known as spotlight. Generally, it can aim in any direction and has a structure that is not affected by climatic conditions. Outdoor LED Flood Lights are mainly used for large-area operation sites and mines, building outlines, stadiums, overpasses, monuments, parks and flower beds, etc. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as floodlights. The angle of the projecting light beam is wide or narrow,…

Why Choose Led Light?

LED Lightssfyh
Why Choose Led Light? Led is One of these big changes in the world.There are plenty of bright benefits: 1.Require less maintenance and last a lot longer than standard lighting. 2.Save on tariffs being more energy efficient. Use about 30% less energy than standard streetlighting technology currently. 3.Save you money on your power bills. 4.Last more than 50,000 hours. 5.Reach full brightness instantly. 6.Contain no mercury or lead which is better for our environment. Emit no UV rays or infrared radiation. 7.Operate at a much cooler temperature, making them a safer option. 8.Cut greenhouse gas emissions and reduce landfill. 9.Are…

What is drive power ?

LED Power Supplysfyh
For lighting, the development of LED has actually entered a new stage, with high requirements for the driving power of the LED light source: High efficiency and low heat generation, because the LED power supply is usually built-in with the LED lamp beads, the heat emitted by the power supply and the LED chip will be superimposed, when the heat generation and dissipation are balanced, the working temperature of the LED light source is finally determined together, and the LED lamp beads work The temperature determines the service life of the LED light source: The led driver power supply has…
