Comparison: CREE and PHILPS $15 within LED lighting design

CREE company and PHILPS company recently announced the launch price of less than $15 is equivalent to 60W-LED light, however, the two companies decided to take a different route in the creative design. CREE lighting launched the A type LED lamp has a full range of light distribution and adjustable light, prices ranging from $9.97 to $13.97. PHILPS lighting is sold for $14.97, and only on the light bulb hemisphere. Both companies have designed the bulb as incandescent, but the structure of the solid state lighting is quite different. The new product indicates that we will see in the near future to replace the 60 watt incandescent bulbs LED lamps for less than $10 price in mainstream stores. In fact, PHILPS North America CEO Ed Crawford promised that the company will launch this product this year.

CREE LED light bulb series in the market there are three styles - $6 price of $9.97, 450 lumens, 2700 K-- 9 watts price of $13.97, 800 lumens 5000K-- $9.5 tile price of $13.97, 800 lumens. PHILPS in the design of the abolition of the light and shade adjustment, lower prices. 10.5 watts of 800 lumens for only $14.97.

PHILPS lamp design

Here, let's look at the interior design of the new light. PHILPS's lamps using remote phosphor technology, launched in December last year, the warm white light, in fact, the white light as the core, on the outer wall painted with fluorescent powder. Although the news that the new 3000K lamps have been greatly improved, but it still uses the same technology. Crawford explained that this new type of lamp using blue LED technology, the phosphor coated on each light-emitting unit. This is different from the popular practice will be coated with fluorescent powder on the inner wall of the second. In other words, the phosphor attached to the LED mold actually coated with phosphor on the first layer of the wall. The new technology will reduce the LED between the outer shell and a light layer, which will certainly save costs, providing light efficiency. However, it will maintain the technical advantages of the LED light source of the heat will cause the gradual change of fluorescent material, the removal of fluorescent material is an important advantage. Crawford said that PHILPS engineers developed thermal management technology makes it possible to apply appropriate fluorescent light source. PHILPS will apply phosphor on the end of the production sequence.

Ed Crawford in the study of the market supply of PHILPS lighting, said: to create a vertically integrated company is very important for us". The company is also looking forward to one day for other solid-state lighting manufacturers to provide such LED products.

CREE star lights

Unlike PHILPS, Cree uses the concept of the LED filament, the incandescent light of the era of the "filament" is now becoming more and more popular in the solid-state lighting industry. In the recently held lighting strategy (SIL) meeting, Intematix announced a small remote fluorescent powder is a type of A filament. Similarly, EPISTAR President MJ Jou called the LED string design called filament. It is clear that the filament quickly becomes a light engine component in the LED retrofit bulb.

It is Cree lighting costs, the internal use of 20 LEDs were divided into 10 groups respectively, and the XT-E LED small customer is priced at $1.5, customers may be less than $1, so the Cree company's internal production cost will be huge, the cost price of the equivalent lamps may account for more than half of the 60W. Silicone coated glass shell and driver (high voltage LED will simplify the driver design) have increased the cost, and Cree commitment to a 10 year warranty period, all these costs are indicative of CREE's profit is slim. Beneficiary is the customer, if the bulb is used frequently, it can be predicted that the payback period of about one year.
