How to use LED dimmable driver in dimming details

LED dimmable driver is one of widely used products in the market. Many people just know the product function, but don’t know how to use LED dimmable driver in dimming details.

a.    Adopting Direct current LED dimming driver technology

It is very easy if you want to change LED brightness. First, you should change the current of LED driver. Because led brightness is proportional to the current of LED driver.

b.    Adjusting the forward current, the phosphors will remove

There is a problem that adjusting the forward current will change LED driver’s chromatographic and color temperature. Because nowadays white lighting is produced by LED drives yellow phosphors. When the forward current reduces, blue lighting brightness is stronger. However, the thinness of yellow phosphors doesn’t decrease.  The main wavelength is longer than before.

c.    Adjusting the forward current, you can not control LED dimmable driver correctly

Because the forward current is not completely proportional to light output. Different LED has different forward current and light output. So it is not easy to control the light control.

d.    The constant current LED driver will not work well if you adjust the current

It is well-known that LED usually drivers constant current drivers. This kind of constant current drivers are divided into high current and low current.

LED Lighting & DALI Dimmable LED Driver are Used in Urban Farm

There was an underground shelter protected the people from the Second World War located under the railway station in London, UK,. After 70 years, this underground tunnel has been converted into an urban farm. The main successful factor is using LED lighting and DALI dimmable LED driver which realizes LED dimming by intelligent control system.

It is very easy for this urban farm to grow the mini green plants. At first, all kinds of seeds are put on the wood fiber, and then these seeds are moved to the shelf exposed by LED lighting after several days. Of cause, you can use DALI dimmable LED driver which works with master controller. The LED lighting keeps bright at 18 hours. According to the specifications of LED dimming, DALI dimmable LED driver can adjust the light intensity. In many countries, the application of DALI dimmable LED driver is mature. We also believe that DALI dimmable LED driver will become more and more popular in China.

The growth cycle of plants is very short. According to the different kinds, all plants grow 6~28 days and then delivery to the London’s high-class restaurant.

In China, the awareness of people’s food security crisis is strong. The requirement of organic vegetables is very large. We can make full use of LED lighting to plant more and more organic vegetables to meet people’s daily requirement. 

There are several advantages of using LED lighting and DALI dimmable LED driver to plant cultures.

a.   Complete kinds of wavelength. You can use specific wavelength of LED lighting to shine the plants.

b.   You can control not only the bloom and yield fruit, but also the plant height and nutritional ingredient.

c.   Long lifespan and strong durability can reduce the cost.

d.   High PPF, good energy saving. If you use DALI dimmable LED driver, it will be more energy saving.

e   To realize the intelligent control, it is very easy to connect with control system. You can use phone APP to control cold and warm white light with DALI dimmable LED driver.

In a world, DALI dimmable LED driver plays a significant role of urban farm. DALI dimmable LED driver has a promising future.  Meanwhile, DALI dimmable LED driver will play an important role in urban farm.

What Hidden Can We Find From Vietnam’s LED Lighting Market and Government Policies?

China’s exports to 70 countries under its “One Belt, One Road” strategy was up 1.5% to US$ 372 billion from January to June 2015, according to China’s custom data. The country’s imports declined 18.8% to US$ 256 billion, while its trade surplus rose US$ 65 billion compared to last year’s US$ 115.5 billion. Vietnam is China's third largest trade partner, and it has a trade surplus relation with the country.


As we all know, many countries vigorously promote energy-saving. Because there will not be enough energy in the world. Our earth we lived in provided the energy is limited. Energy is not only the method the countries save costs, but also the policy which benefits the sustainable development of human beings. In 2015, countries do more to promote the development of DALI dimmable driver. So What hidden can We find from Vietnam’s LED lighting market and Government policies?

Government's full support creates the perfect timing for LED manufacturers to enter the market. In 2005, the Ministry of Industry and Trade (MOIT) approved national energy efficiency and conservation 2006-2015, which known as the Vietnam Energy Efficiency and Conservation Program (VNEEP). VNEEP aims at increasing energy efficiency and reducing energy consumption by implementing varied procedures. Vietnam promised to reduce import tax after joining WTO in 2007. At the end of 2008, Vietnam made 1%-5% tariff discount toward ASEAN counties based on Common Effective Preferential Tariff (CEPT). By 2014, the tariff was reduced to an average of 13.4% and implement zero tariff toward general products by 2015.

The Vietnamese government rolled out a US$ 90 billion urban upgrading project, aiming at 70% of urbanization by 2020. The urban upgrade project will further stimulate Vietnam's architectural lighting market, especially residential lighting, commercial lighting, hotel lighting, resort, entertainment and infrastructure lighting.
