Abstract: The light-emitting module according to one embodiment comprises first to Nth light-emitting element packages (wherein N is a positive integer greater than or equal to 1), which are connected in series to one another, and a current level regulator for regulating the level of current flowing through the Nth light-emitting element package. Each of the first to Nth light-emitting element packages comprises a light-emitting cell comprising a plurality of sub-cells, which comprise at least one light-emitting element and are connected in series or parallel to one another, and a flicker control unit, which is connected between the plurality of sub-cells and selectively forms the path of current flowing through the light-emitting cell according to the level of an external driving voltage. At least one of the first to Nth light-emitting element packages further comprises a first current control resistor connected to the output of the light-emitting cell.

Abstract: The present invention provides a method for mass production of silicotitanate at low costs using SiO2; and a cesium adsorbent containing silicotitanate in which Na+ is substituted with H+ by acid treatment of Na-silicotitanate. The cesium adsorbent according to the present invention may be used in a filter for purification of air and water, and also as an agent for restoring soil, atmosphere and ocean contaminated with nuclide materials.
