How to choose suitable LED power suppliers?

The load characteristics of LED determine that only power suppliers with higher reliability can be used. Within a certain section, increasing the external voltage will cause an exponentially increased current. When LED Lights work in the normal condition, subtle changes in voltage will cause widely vibrations in current. Thus most switching power suppliers are no longer suitable for LED applications. Because the output of switching power suppliers is not a constant value. However, how to choose ...Continue reading

Subject to the core technology, indoor LED lighting products hardly to go further (3)

This type of government leading developing mode has been questioned by many experts and insiders. They generally thought that the excessive government support will give birth to the dependency of domestic LED manufacturers. They will be keen to project biddings rather than promote innovations in products and market. In fact, this tendency is obvious. Many LED manufacturers would like to apply projects under explicit state policies to enjoy the subsidies. In Mr. Wu’s opinion, LED high bay lightin...Continue reading

Subject to the core technology, indoor LED lighting products hardly to go further (2)

However, crises of energy-saving lamps have become chances for LEDs. It is a controversial topic that whether indoor LED lighting products can finally replace energy-saving lamps. The industry is generally of the view that LED lights and energy-saving lights are two independent products within two distinguished stages of lighting development. They may coexist for a long time. Hong Wu, chairman of Shanghai Lighting Society indicated that energy-saving lamps will not be replaced by LED in next thr...Continue reading

Subject to the core technology, indoor LED lighting products hardly to go further (1)

Since the beginning of the year, LED lighting products have become the new darling for policy and fund. Support policies and subsidy programs keep emerging. LED lighting business started to revive from the global economic depression. However, behind the seeming recovery, LED lighting industry still has many cannot-be-ignored problems: lacking of upstream chip technologies, domestic LED lights manufacturers either fluctuate in low profit downstream or produce low quality LED chips. Therefore, ind...Continue reading

Five Problems of LED lighting lamp industry (2)

Right now, nearly 80% LED projects are used in public works. Applying LED technique in civilian projects still need the support of government. After ten years development, LED lighting lamp industry met with its first bottleneck. LED manufacturers thus desired to be involved in more civilian projects. Since LED lamps are normally more expansive than traditional lights, it is hard to be accepted by ordinary families. Due to the low demand of residential LED lighting products and also the low prof...Continue reading

tri band led grow light for track lights led

As we all know, the single LED high bay is low power in tri band led grow light track lights led. In order to obtain high-power, multiple parallel, for example, automobile taillights, single high-power LEDs are very expensive. One drawback is that the "spot", the white tri band led grow light manufacturing defects in workmanship coupled with the errors of the reflector or lens, likely to cause a yellow circle. The disadvantage or weakness of the current semiconductor lighting in the following...Continue reading
