LED bulb having electro-conductive plastic lamp seat

A co-injection moulded plastic lamp seat used in conjunction with a LED bulb includes an insulating base (11) separating a plastic conductive electrode (131) and a plastic grounded electrode (121). The conductivity of the electrode material may be determined by adjusting the proportions of different metallic materials doped into plastic material, so that the input voltage is reduced during transmission, simplifying the need for an internal circuit to step down the voltage. The electrodes (121, 131) may have an electrically conductive material e.g. metal, disposed as a layer on top. The LED light source may comprise multiple LEDs arranged to form a rectifier. The bulb may be provided with a fastenable cover (3).

Acoustic board having displaced and passably abutted multiple through holes

An acoustic board having displaced and passably abutted multiple through-holes comprises an outer surface and an inner surface, in which the first through-holes formed from the outer surface toward the inner surface and the second through-holes formed from the inner surface toward the outer surface are displaced and passably abutted thereby conjunctively constituting acoustically absorptive micro-orifices. Herein at least some of the second through-holes have a cross-sectional area of greater than 1 mm 2 and are displaced and passably abutted to at least some of the first through-holes, thereby collectively forming a plurality of acoustically absorptive micro-orifices having a cross-sectional area of smaller than 1 mm 2 , and, in comparison with the total area of the acoustic board, the opening rate for the sum of the cross-sectional areas of all such acoustically absorptive micro-orifices is less than 3%.
