Osram good. Osram as the world's second LED light chip manufacturer his popularity is beyond doubt, a penny a goods, OSram lampWith very good, the brand's reputation is good, the variety of products is complete, the quality is guaranteed, safe and reliable. From the lighting chip brand, of course, the best chip brand is Cree, but the price is not cheap, followed by Osram, Pry, Philips, crystal, the above is the most commonly used several brands, but also the most used, the most stable. At the same time, each chip brand chip is also divided into several levels.
OSram and Cree are well-known manufacturers of electronic components, and their high-power chips are widely used in different markets and applications. If you need to buy, suggest DobieCompare products from different manufacturers to see which one better fits your needs and budget.
Long life: OSram's LED chips have a long life, can continue to work steadily, reducing the frequency and cost of replacement. Energy saving and environmental protection: OSram's LED chips can effectively reduce energy consumption and achieve energy saving and environmental protection.
And LED lamp bead brand is better Samsung, Philips, Cree, Osram. The way to distinguish LED beads is as follows to see the brightness, that is, how much is the brightness when the drive current of 350mA and the voltage is between 0-6V, the higher the better.
The advantages of the chip, this specific according to their own situation to select, for example, the current white chip and lamp bead performance is the United States CREE, expensive, belongs to the high-end imported brand, of course, the performance is also very excellent.OSram Naruto is an original import. Osram Naruto is imported, OSram Naruto is produced in Munich, Germany is originally imported, OSram is famous for its excellent light source products.
OSram has factories in China. Osram entered China in 1995 and is headquartered in Foshan with subsidiaries in Shanghai, Wuxi, Shenzhen, Guangzhou, Kunshan and Hong KongBranch agency. It has four production sites and five research and development centers in China, with a total of 4,300 employees.
The recognized ranking is the United States CREE Cree Germany OSRAM OSRAM Japan NICHIA in terms of domestic mainstream or use three an good point is the wafer, light macro is also good. Do LED lights according to the domestic production and marketing mode is mainly a low-end chip.
Now there are very few lamp beads imported, most of them are Taiwanese chips, packaged in China, like many foreign brands are foundry in China, including Philips.
1, the chip of the wafer, the electrode is symmetrical in the middle, and the P electrode has two small tails. Osram didn't use it. I don't know.
2, the difference between the patch and 3528 patch: turn left | turn right turn left | turn right turn 2835 adopts the whole surface luminous scheme, which has high luminous efficiency and luminous area of 18MM, which is twice that of 3528 lamp bead. 2835 high brightness, a single up to 22 lumens (LM), the brightness is 3528 lamp beads8x the 3014 lamp bead.
3, different luminous intensity: 2835 lamp width is wide, making the luminous area is large, the light rate is high, and the intensity can reach 13-15lm. (3) The packaging process is different: 2835 light belt is the chip directly through the heat sink, heat dissipation is better.
4, the light concentration of the two is different, and the range is different: the Angle of the LED lamp bead is very small, which is a relatively concentrated light, and the range is very far, but the irradiation range is limited; The general Angle of the LED patch is very large, which belongs to the relatively scattered light, wide irradiation range, but the range ratioIt's near.
5, Taiwan's Epistar is short for: ES, (Lianquan, Yuankun, Lian Yong, Guolian), Guanggallium Optoelectronics (Huga), New Century, Guanghong, etc.
1, three ampere chip is better than Osram. SAN 'an chip focuses on the production of high-quality semiconductor chip products, the company strictly controls the production process of the product, and implements multiple quality testing of the product to ensure the stability and reliability of the product.
2, all good. threeAn chip from Xiamen SAN An Integrated Circuit Co., LTD. (referred to as "SAN An Integrated") is located in Xiamen Torch (Xiang 'an) high-tech development zone, the total planning of the project land 281 acres, a total investment of 3 billion yuan.
3, three Ann lamp beads than OSram lamp beads to be a little less, so Osram lamp beads are brighter.
