Abstract: A landing pad is provided. The landing pad includes a first body, a second body, an elastic component, and a fastening component. The first body includes a pad portion and a first coupling portion. The pad portion is configured for landing of a drone. The first coupling portion is connected to the pad portion. The second body includes a mounting portion and a second coupling portion. The mounting portion is configured for mounting to a position to be mounted. The second coupling portion is connected to the mounting portion. The second coupling portion is configured for coupling with the first coupling portion. The elastic component is disposed between the first coupling portion and the second coupling portion. The fastening component is configured for combination of the first coupling portion, the second coupling portion, and the elastic component.

Abstract: A visibility meter, a street light device and an operation method thereof are provided. The visibility measurement method includes: transmitting a visible laser through an optical transmitter; receiving the visible laser through an optical sensor to generate a sensed result; and calculating a visibility according to the sensed result.

Abstract: An illumination device including a lamp and a light shielding hood is provided. The lamp has a front lamp cover with a light exit surface. The light shielding hood at least partially covers the light exit surface for reducing the light energy emitted from the lamp, and has a transmittance less than a predetermined value.

Abstract: A light source module including a substrate, an LED package, an optical cover, and at least one packing layer is provided. The LED package is disposed on the substrate and includes an encapsulant. The optical cover is disposed above the LED package. The at least one packing layer is filled between the LED package and the optical cover.

Abstract: An illumination device including a lamp and a light pole is provided. The lamp has a first assembling structure. The light pole has a second assembling structure. When the lamp moves closer to the light pole, the first assembling structure and the second assembling structure are automatically locked together by transmitting and receiving a signal. In addition, an installing method of an illumination device is also provided.

Abstract: A pole fixing structure for fixing a lamp is provided. The pole fixing structure includes a multi-axial adapter and a positioning structure. The multi-axial adapter includes a fixed seat, a movable seat and a steering member. The fixed seat has first and second axial pole inserting holes. The movable seat has first and second size openings. The first size opening corresponds to the first axial pole inserting hole. The steering member is disposed on the movable seat in the first axis, wherein the movable seat rotates around the steering member with respect to the fixed seat, so that the second size opening corresponds to the second axial pole inserting hole. The positioning structure is disposed on the multi-axial adapter for fixing the first axial pole in the first size opening or fixing the second axial pole in the second size opening.
