Analysis of the status quo and development of LED driver market

Today, the LED market is still immature, we have seen the "bloody" that is not used to it! Do you think that the LED lighting industry market is achieved by low-cost driver ICs? According to incomplete statistics, the best LED The cost of the driver IC in the entire LED luminaire is less than 6%! What we have to do now is how to bring out the advantages of LED, how to find the most suitable driver and design to meet the long-term development of LED lighting, how to The advantages of LED play out, and even how to promote and guide the healthy and correct development of the LED lighting industry! When the product is not mature, blindly do low quality, low reliability, bottom cost, products without innovative ideas, maybe you can Get some feedback in the shortest time, but in the end it is the end of being eliminated to the end!

Recently, many customers have found me, saying that their MR16 has been sent to Europe and other places, and they have received feedback from customers. A considerable number of regional electronic transformers can't adapt, flashing, not lighting, etc. Caused by returns. I hope we can provide him to solve this problem. The solution to the problem. MR16 is limited by the appearance and application, mostly with a single 3W or 3 1W and 3 3W LED lights, most of which use 3 1W solutions. Let's talk about electronic transformers. This thing can Said to be the "garbage power" of the technology product. When it is used in pure resistive load, he shows quite good efficiency and power factor, but when used in small load and inductive or capacitive load, it has poor output. A mess! Even after full-bridge rectification and filtering (the filter capacitor is not big enough), sometimes the average voltage is 7~10V, which makes some BUCK circuits unbearable. Now most BUCKs use "hysteresis" current detection, which makes the load and The requirements of the power supply are relatively constant. When the power supply or load changes more than a certain condition, the LED constant current performance of the IC is believed to be experienced by many friends. Even if some people still think that "most of the time is OK, Or few customers ask or mention ", just release such a product! As a designer, I think this is irresponsible for the product, irresponsible for the company, and even irresponsible for the entire LED industry!

However, there are some good products, such as the use of a single 3 watt, may be improved. There are also good drivers can use BUCK-BOOST structure to easily solve this problem, but there are always people willing to use price to compare performance, through the market The test finally led to the problem returning to the original point, throwing: "Under the premise of solving the problem, do not consider the price!" In fact, cost-effective, this is what everyone wants, but when performance can not meet the requirements It doesn't make any sense to start a price war, because the end user will tell you that your product is a failed product...! After saying so much nonsense, I finally want to tell friends who are engaged in the LED industry, everyone working together, Do the best products that have been thought out, and maximize the benefits! Make LEDs into a real sunrise industry instead of making a sunset industry. Price is not the key to success or failure. Wisdom and technology are the source of wealth!!!

As the original Flip Clock maufacturer, factory has been in clock industry for over 20 years, with rich OEM experiences in clock, and great ability in new product R & D.

Our flip clock product lines including Flip Wall Clock, Flip Desk Clock, alarm flip clock, Flip Clock With Light, flip clock with seconds, etc, and almost all of our clocks accept customization in LOGO, designs, colors, functions, and package etc.

These flip clocks are not only our orginal designs, but owing patent protection in China, they have been widely sold to Europe countries, like The Netherlands, Spain, Italy, Germany, France, UK etc, Americas, Middle East and Asia like Japan, Korea etc.

These flip clocks are operated by batteries, driven by our self-developed powerful movement, time's showed by numbers, the left side is hour display card, and right side is minute display, time can be showed either in 12 hr or 24 hr, the number card falls down automatically every minute, the clock is working silently.

A nice clock and table display for home decoration, as well as good choice for corporate gift or business gift.

The number card is customizable to print corporate LOGO or company products as auto display.

It is for indoor use only, as the exposed gears and exposed flips need to be keep dry and clean.
