Abstract: A deck plank has at least one base, a top board and two reinforcing ribs. The at least one base includes a carrier board and a plurality of support columns. The support columns extend from a bottom surface of the carrier board. The top board is mounted on a top of the at least one base and has two receiving cavities therein for receiving the reinforcing ribs. To construct a deck, a plurality of deck planks are placed side by side on the ground. The top boards are spaced from the ground by the support columns of the base such that the moisture from the ground does not penetrate the top board to cause the top board to become damp and rot. In addition, the top board is structurally reinforced by the reinforcing ribs to prevent deformation.

Abstract: A white light bulb assembly includes a cylindrical body with an annular projection extending from a bottom face of the cylindrical body, a bulb covering securely mounted on top of the cylindrical body, and multiple light emitting diodes provided inside the bulb covering to electrically connect to the annular projection and a circuit board located inside the bulb covering. The bulb covering has multiple first grooves defined in an outer circumference of the bulb covering and multiple second grooves defined in an inner circumference of the bulb covering to reflect and refract light from the light emitting diodes. The first grooves intersect the second grooves in an angle so as to reinforce the reflection and refraction of light.
