Abstract: A Zigbee network system comprises a backup Zigbee coordinator, a Zigbee coordinator, and at least a router, and the network group data is instantly copied to the backup Zigbee coordinator. In this way, the backup Zigbee coordinator can replace the broken Zigbee coordinator, so that there is no need to restart the Zigbee network system. Accordingly, user can seamlessly transmit the data through the Zigbee network system without the influence of the broken Zigbee coordinator.

Abstract: A lighting apparatus including a base, a light cover, an optical element, and at least a light emitting element is provided. The light cover having a first opening is disposed on the base and together with the base forms a space. The optical element is fixed on the light cover and substantially covers the first opening of the light cover. The light emitting element is disposed in the space. A light emitted by the light emitting element passes through the optical element and emits from the light cover to form an illumination property of the lighting apparatus, wherein the light cover together with the optical element is movable with respect to the light emitting element. When the light cover and the optical element have different relative positions with respect to the light emitting element, the illumination properties are different.

Abstract: An illumination device includes a lamp housing component, a main bone disposed inside the lamp housing component, and at least one light emitting component. The light emitting component has a heat sink member and a light emitting member. The heat sink member is locked on the main bone, and the light emitting member is disposed on the lamp housing component and contacts the heat sink member. According to the demand for luminance, the number of light emitting components is optionally increased or decreased on the main bone, or the main bone inside the lamp housing component is replaced by an extended main bone, so as to increase the number of light emitting components.

Abstract: A cooling method for an LED lamp is disclosed. An LED lamp is provided. The LED lamp includes a housing and at least one LED light source module. The housing has a cover body, a base and a plurality of air outlets. The base forms at least one segment difference portion. The slanted surface of the segment difference portion has a plurality of air inlets. The LED light source module is adjacent to the air inlets. The LED light source module has a cooling device and the cover body has a plurality of air outlets. Airflow is guided into the cooling space along the air inlet on the slanted surface of the segment difference portion. When the LED lamp generates heat, air entered into the cooling space is blown to the cooling device. The airflow with heat is exhausted from the air outlet of the cover body.

Abstract: An LED light device module includes a housing, a light source structure and a power supply. The housing has a cover body and a base body. The cover body is located on the base body. The light source structure is located in the housing. The light source structure includes a cooling device, an LED light source device and a secondary optical device. The LED light source device and the secondary optical device are located on the cooling device. The LED light source device is located between the cooling device and the secondary optical device. The power supply is located in the housing and electrically connected with the light source structure. Thereby, the system cost is reduced, the total weight is low, it is easy to manufacture and maintain. The LED light device module can be expanded and the outline of the LED light device module can be designed flexibly.

Abstract: A data protecting system includes a storage device for storing a data unit having an index data and a content data, an input interface for inputting a specific set of codes, an encryption module for encrypting position of an initial cluster of the content data and saving the same in the index data and a central processing unit for processing the position of the initial cluster and the specific set of codes and later storing the position of the initial cluster and the specific set of codes within the index data after completing encrypting operation thereof.
