Low cost light bulbs sold: why CREE so cock?

From 2012 to the present CREE has launched 9.5W, 13.5W and recently released 11W, 6W low cost series of products, CREE launched a total of 15 different specifications of the bulb.

In the CREE bulb family, the recent release of low-cost series of attention. Focus on: the design of the entire bulb bulb is not the ordinary LED lamp radiator, but also different from other CREE products using glass bubble. The product is made of plastic foam shell, the top of the shell and the end of the hole, so that the air convection to heat. Bulbs do not use aluminum substrate, but the use of double-sided FR-4 plate forming cross cross arrangement, each side of the welding of a CREE production of their own LED. Power is also placed in the plastic shell and the E27 lamp holder.

The internal beads, XB-E High Voltage, the 9.5W, and before the release of the 13.5W light source used in the same series. From the point of view of the product line, CREE bulb lamp cooling platform universal, light source platform generic. Based on the same cooling platform CREE also released BR bulbs and PAR lights, based on the development of the platform is CREE's strengths. From the SIC platform to develop a number of chip platform, the use of a variety of chips to develop a variety of light source platform, and then use the light source platform to develop a series of bulb. In this regard, CREE has done very successful, few domestic companies can do so platform, serialization, the expansion of the development route.

To see such a small bulb, reminds me of the PHILIPS before the release of the flat shape of the bulb, the two designs have the same effect! Such a small light bulb, its photoelectric parameters?

When you get the physical, detailed disassembly. The first thing we can learn from this: the whole process of the lamp assembly does not require the use of iron, do not need to use a screwdriver!

A, PCB:

PCB is double sided board, the PCB line is of high precision, the design of the hole position is very detailed, and it can be assembled by the way of upper and lower insertion. Taking into account the absorption of light on the PCB surface, the ink on the PCB is a highly reflective ink.

Two, connection mode:

All line connections have shrapnel and contacts. Contains contact between PCB and PCB and lamp holder contact.

One of the two shrapnel on the bottom of the PCB is the middle point of contact with the lamp holder.

Three, power:

The power supply is integrated in one of the welding beads from the PCB, connected with the power supply and the lamp board PCB.

Four, lamp:

The use of large angle and 8 CREE own production of high voltage LED lamp.

Before the network has reported that CREE and the Ronda cooperation bulb market could drive the Lunda business. It seems that in bulb on the currently used are CREE their beads, has nothing to do with lextar. Torgovnik

Five, cost:

From the perspective of the power components, some of the authentication and security requirements are met, the components of the price should be high, plus the lamp cost, the total cost should be low. Why buy such a low price? This problem is worthy of our consideration. Torgovnik

Not afraid of God as rivals! Now for China's LED lighting companies, in the field of lighting in the traditional Philips, OSRAM such a century enterprise. There are like CREE to enter the industry to achieve a high level, and then vertically integrated enterprises. Our LED lighting companies are still relying on lower labor costs, lower priced devices to break it? See

CREE ball bubble lamp, I am a bit pessimistic, the future of the light source market, Chinese companies may increasingly lose their competitiveness, can only earn a processing fee. Even if the enterprise such as sunshine, export volume so high, there are several products are their own brand? Technological upgrading and industrial restructuring of the country called for many years, but to see a new industry and then take the traditional road, this is fate? I hope the same gas, "! .
