The popularity of the current projector has brought convenience and efficiency to the daily work of the majority of business people, but the problem of excessive consumption cost has not been effectively improved. Recently, NEC released the new product NP63 +, trying hard to reduce the use and maintenance cost for all enterprises while realizing the sustainable development of resources by virtue of its original second-generation "air pump cooling system". This projector can save energy, reduce costs on the pack, the main unique weapon. First, anyone who has experience in using the projector knows that the heat generated by long-term operation of the projector can have a significant impact on the life of the lamp, especially for projectors that use ordinary fans to cool the room. Temperature can not be dissipated, the cooling effect is difficult to perfect. The NP63 + uses a unique, second-generation air-cooled pump technology to solve this problem of lamp wear due to heat dissipation. Its air-conditioning pump can directly aim at the maximum heat source of the projector, that is, the lamp's wick, hair cool, greatly improve the cooling efficiency, to ensure and enhance the service life of the lamp, thereby reducing the maintenance costs caused by the lamp loss replacement, the maximum Limit the use of reduced costs. This is particularly suitable for large-scale procurement of projectors for business users. Secondly, the NP63 + can also be properly handled for the problem of slow and feeble electricity consumption caused by the projector often encountered in use. The user can not only set the automatic shutdown time, but also automatically shut down the backup signal when no operation signal is received for a period of time, so as to avoid unnecessary waste of electricity, which is both environmentally friendly and economical. In addition, the NP63 +'s ingenuity is also reflected in the compact size, B5 size, 1.7KG weight, creating the world's ultra-light 3,000 lumens ultra-portable projector.
