On April 3, 2014,
CREE announced that the light efficiency was 303LM/W at a standard room temperature (25°C) for a LED with a color temperature of 5150 degrees K for 350 mA! This is an epoch-making initiative in the history of lighting!
Let us review the company's history of LED light efficiency, as shown in the table below:
According to the "Moore's Law" of semiconductors, and other related predictions, the LED light efficiency improvement curve and the curve of the LM unit price per thousand are expected. The difference between the two curve prediction intersection points corresponds to 2015, and the forecast indicates that 2015 is the LED industrialization. The most suitable time to cut.
I don't see you. In 2012 and 2013, some investors did not investigate the "Moore's Law" of LED, blindly cut Li Mingfeng's column into the LED industry, and purchased foreign low-efficiency LED old products that were dumped in foreign countries (equal to the foreign LED upstream industry company). Paying for the early R&D expenses) When the long-term negotiation arrives at China, the higher cost-effective LED CIF price is lower than the low-efficiency LED FOB price that was originally eager to purchase!
Therefore, the early low-efficiency LED became the price of tuition, and the low-efficiency LED became a hot potato. It had to be equipped with an emergency bidding LED light source, and the power supply purchased at a low price was quickly matched with a low-cost LED lamp. The price market is somewhat competitive; however, a penny is worth the price, low-priced bidding to buy unreliable power supply, with low-cost LEDs with low-cost purchases, can it be expected to pass the light decay test? The return is inevitable tragedy, so those who talk about the LED boss jumping off the stairs, those about the LED boss running, are not strange.
The US official published a forecast a few years ago. It is possible that by 2015, when LEDs cost less than $1 per LM, in the lighting industry, the creation of brand-name LED lamps will compete with known lighting products. Winning in the middle.
Incandescent bulb light efficiency, about 15LM/W (common bubble), to 25LM/W (halogen tungsten lamp). The statutory incandescent bulbs in various countries around the world have been discontinued for sale, which is to clear the way for the high-efficiency LED industrialization, with the aim of reducing carbon and ecological protection for the earth!
The president of the American LED Association publicly commented: "China LED has no brand!"
What is the "competitiveness of LED"?
The first is the brand!
The second is (performance is numerator, price is denominator) cost-effective!
China LED has not yet established a high-reliability conversion, lack of independent intellectual property rights as the core technology of the brand awareness, can not enter the United States-led invitation to join the (PTT) Pacific Rim Free Trade Zone.
Since China's LED industry does not attach importance to creating independent intellectual property rights, due to the current low awareness of China's LED brand, China's LED products have no brand premium capability during trade negotiations. Those middlemen (or hackers) with orders in hand are raising their bargains. How many Chinese LED foundry companies kill! China's sweat economy, Cheng also OEM, defeat also OEM!
More terrible is the collapse of low-cost competition among domestic LED companies! Formally commit suicide! Sad and sad!
From the current announcement of LED light efficiency to break through 300LM/W, to the industrial production of 300LM/W high-efficiency LED, the price of LED has dropped to 1 US dollar per 1000LM. I am afraid I have to wait for some time. On the day, the global LED light efficiency competition prelude has been opened, and the current low-efficiency LED price reduction promotion will become more and more intense; the contemporary LED light efficiency is increasing rapidly, which has led to the urgent need for cost-effective and high-reliability constant-current power supply. Matching power supply will also trigger! Let us work together to quickly match the
LED lamp beads with high reliability power modules to support the creation of LED brand names!
