Abstract:
A are provided a light source module. The light source module including a light emitting device configured to emit light in a light emitting direction; and an optical device including a first surface disposed over the light emitting device and having a groove recessed in the light emitting direction in a central portion through which an optical axis of the optical device passes, and a second surface disposed opposite to the first surface and configured to refract light incident through the groove to be emitted to the outside. The optical device includes a plurality of ridges disposed on the second surface and periodically arranged in a direction from the optical axis to an edge of the optical device connected to the first surface.
Abstract:
A lighting device is provided. The lighting device includes: a light source module mounted on a substrate; a lens unit provided on the light source module and including an accommodating groove accommodating the light source module; a housing unit accommodating the lens unit therein to protect the lens unit from an outside; a supporting unit fixed to the substrate and including a coupling hole having the housing unit coupled thereto to thereby support the housing unit; and a height adjustment unit allowing the housing unit to be vertically-movably coupled to the supporting unit and adjusting a height of the lens unit such that the height of the lens unit is varied.
Abstract:
A light emitting diode (LED) package is provided. The LED package includes an LED, a plurality of lead frames electrically connected with the LED, a package body having a receiving groove exposed to receive the LED therein and including a plurality of supporting units provided to project from an inner side surface of the receiving groove, and a filling member having an engaging groove engaged with the supporting unit at a circumference of a side surface thereof, and included inside the receiving groove.
Abstract:
An apparatus for filling insulation material consists of a vibrating means; a lift driving means for lifting the vibrating means; a horizontal transporting means for horizontally transporting the vibrating means and the lift driving means along the guide rail of the storage tank; an automatic winding means; a level sensing means for checking the amount of filling of the insulation material; a flux preventing means for securely maintaining the flux in the horizontal direction and verticality of the vibrating means; a descending position sensing means for restricting the descending position of the vibrating means by touching the insulation material; a control means for checking the amount of the insulation material filled along with automatically remote controlling the vibrating means, the level sensing means and the lift driving means; and a display means for directly observing the inside through a camera.
Abstract:
A light emitting diode (LED) package refracting or reflecting light emitted from an LED chip is disclosed. The LED package may include a substrate, an LED chip mounted on the substrate, a lens unit formed by injecting an encapsulant adapted to enclose and protect the LED chip, and at least one refraction member disposed in the lens unit. The at least one refraction member may refract or reflect the light emitted from the LED chip.
