Circuit board is a great impact on the performance of LED lamps, the common cardboard, semi-glass plate, all glass plate, aluminum plate, as well as single-sided double-sided subdivision.
From the cost point of view, the cost of the first two are the lowest, the most expensive aluminum plate.
Now the price competition so intense, many manufacturers choose a half-wave board, after all, poor performance cardboard, but there are a few will be used. Half-wave fiber board, part of the glass fiber, and some are chemical fiber or cotton resin high-pressure high-temperature synthesis.
The whole glass fiber is all glass fiber and high heat resistance composite epoxy resin synthesis, with sound absorption, sound insulation, heat insulation, environmental protection, flame retardant and other characteristics, electrical insulation performance is stable, heat, Performance than half-wave board is good, high specifications of the whole glass fiber board can even be comparable to the aluminum plate.
The aluminum plate is mainly excellent heat dissipation, suitable for LED lighting needs of this feature, high-power LED lamps with aluminum plate more, but the aluminum plate can not do the hole.
