(相當于十級臺風)，根據非粘性流體力學，電池組件承受的風壓只有365Pa。強大制造業(yè)系統(tǒng)使得中國能夠研發(fā)制造出比較好的LED照明產品。防水三防燈質量保證</p><p style="text-indent:25px">LED面板燈應用在其它(還可用在其它地方，如火車車箱或者大型移動車內、柜臺等)。北京批發(fā)三防燈</p><p style="text-indent:25px">一般的LED支架是經過金屬沖壓再注塑所形成。LED作為發(fā)光二極管，需要對金屬內表面進行電鍍處理，銀作為良好的光反射材料，所以一般LED為電鍍銀表面處理。各種不同功率的LED采用的支架材料也不相同，小功率一般采用PPA、中功率一般采用PCT、目前有一些大功率采用EMC材料制作。所有的塑膠材料都有吸水性，所以在LED燈珠生產過程中對支架需要進行烘烤的除濕處理。電鍍層的處理是支架的關鍵點，鍍層厚度和質量關系著后面的光通量、焊接性能。北京批發(fā)三防燈</p><p
