Different from PLCC high thermal resistance bracket structure and high production cost ceramic structure, 2828 (2.8mm x 2.8mm x 1.5mm) series follows the patented copper substrate encapsulation technology of Ricoh Optoelectronics, which has high luminous efficiency, fast heat conduction and light output. Quality and price are also competitive in the market.
2828 LED Specifications:
1. Light color 2700K: 0.3W average 90 lumen/w, 0.5W average 80 lumen/w, color rendering > 90
2. Light color 5500K: 0.2W average of 160 lumen/w, 0.6W average of 100 lumen/w, color rendering>75
The new 2828 series has a very good light color effect in indoor lighting, such as: T8 tube, cabinet light, light bulb, projection lamp, downlight, etc., all have no dark area problems.
At the same time, the newly developed optical reflectors are available in projection lamps for MR16, PAR20, PAR30, PAR38 & AR111, and are available in 25°, 35°, and 55° angles. In order to make it easy for customers to design high-quality LED lamps, in addition to supplying 2828 series LED packages, Ricoh Optoelectronics also provides power module solutions to assist in the design of LED lighting products.
