Abstract: A method includes preparing a natural seashell, calcining the seashell at a high temperature to clear organic substances from the seashell, processing and reacting the seashell at a high temperature, grinding and screening the seashell, and mixing the ground seashell with microorganism strains to form a water deodorizer. The water deodorizer includes a powder having a porous structure, and multiple microorganism strains mixed with the powder. The powder has an interior provided with a plurality of pores. The powder is made of a natural seashell which is processed at a high temperature, and is ground and screened to form the porous structure. The microorganism strains are filled in the pores of the powder and cover outer surfaces of the pores of the powder. The powder has a diameter of 0.4-10 ?m.

Abstract: A method includes preparing a natural seashell, calcining the seashell at a high temperature to clear organic substances from the seashell, processing and reacting the seashell at a high temperature, and grinding and screening the seashell, to form a water purifying agent. The water purifying agent includes a powder having a porous structure. The powder has an interior provided with a plurality of pores. Thus, the water purifying agent is used individually or served as a carrier of a microorganism for a specified purpose, so as to purify the water quality. In addition, the water purifying agent has a high specific surface area and has a better adsorption capacity.

Abstract: A method for making an LED lamp includes a first step of working a base plate, a second step of placing the base plate in a die cavity of an injection molding machine, and a third step of forming a housing in the die cavity of the injection molding machine to combine the housing with the base plate. The base plate is integrally combined with the housing completely by injection molding so that the base plate and the housing are combined closely and solidly and will not detach from each other.

Abstract: An LED lamp includes a housing, a base plate combined with the housing, and a plurality of LED crystals combined with the base plate. The LED crystals are connected serially, and a total allowable voltage of the LED crystals is equal to or greater than a voltage of an external power supply. The base plate is integrally combined with the housing completely by injection molding so that the base plate and the housing are combined closely and solidly and will not detach from each other. In addition, the LED lamp does not need provision of a drive device.

Abstract: An LED lamp includes a heatsink housing (2) and an alternating current LED module (1). The alternating current LED module includes a heat conducting portion (10) combined with the heatsink housing and two electrical connections (11) electrically connected with an external power supply. Thus, the heatsink housing forms a porous structure to provide a greater heatsink effect and to quickly carry away the heat produced by the alternating current LED module to enhance the heat dissipation efficiency of the alternating current LED module. In addition, the heatsink housing is directly formed to have the profile of a common lamp housing and is provided with a metallic screw base (21), an insulating gasket (22) and a power contact plate (23) so that the heatsink housing can be mounted on a traditional receptacle to replace the conventional electric bulb.
