Cree LED flashlight is not only another name of keychain torch, but also one of the most commonly used energy-saving lamp beads in the current LED lighting industry. Compared with traditional halogen bulbs, Cree is an innovative LED lighting technology, and its bright light intensity and energy-saving advantages have been recognized by the market. In fact, many people also recognize the technology of COB lamps. Chip on board (commonly known as COB) is another lighting solution for LED lighting. Its distinctive feature is that multiple LED chips are directly mounted on the top of the substrate to produce a single module. Therefore, it is very necessary to distinguish the specific functions of Cree and COB lamp beads.
Both Cree and COB belong to LED lighting technology. The difference between the two is that Cree is a mercury-free LED technology. This technology can not only play a greater brightness in outdoor flashlights, but also in new energy solutions, brighter and adjustable LED light There are exciting options for lighting (LEDs), brighter backlight displays, optimal power management for high current switching power supplies and variable speed motors, and more efficient wireless infrastructure for data and voice communications.
COB flashlight is the smallest type of LED lamp beads. In terms of circuit design, COB has the function of about 9 or more diodes, including two contacts and a circuit, which may be related to the number of diodes. Research has proven that COB LED lights are not suitable for lamps or bulbs that produce color change. In terms of energy consumption, the COB system has a greater thermal efficiency and an enhanced lumen/watt ratio, and the design of the ceramic substrate and the COB system has important implications for this.
