A luminaire includes a base, a light-emitting unit, and a lamp cover. The base includes a first tube part, a second tube part having an inner diameter smaller than that of the first tube part, and a joint part connected between the first and second tube parts. An inner flow path is defined by at least the first tube part, the joint part, and the second tube part in a coaxial manner. The lamp cover is fixed on the base for covering the light-emitting unit. As such, air heated by the light-emitting unit flows out of the inner flow path to thereby allow cold air to be sucked into the inner flow path.

An illumination device having enhanced thermal dissipating capacity is provided. The illumination device includes a heat sink, an LED module, a cover, an LED driver, and a lamp base. The LED module is disposed at one end of the heat sink. The cover covers the LED module. The LED driver is in connection with the LED module, and includes a circuit board and at least one electrical contact member disposed on the circuit board. The lamp base is connected to the other end of the heat sink, and comprises an insulating unit, a first electrode, a second electrode and at least one contact port. The contact port is arranged on the lateral interior of the insulating unit, so that the electrical contact member of the LED driver may establish electrical connection with the lamp base.

An illumination lamp comprises a lamp body, a light-emitting module, a power supply module, and a circuit module. The lamp body defines an inner space. The partitioning unit is disposed in the lamp body for dividing the inner space into a first space for receiving the power supply module, and a second space for receiving the circuit module. Due to the presence of the partitioning unit, thermal convection between the first and second spaces is prevented to reduce adverse influence of a high temperature of the circuit module on the power supply module.

A light-emitting device includes a light-emitting element and a heat-conducting and electrically-insulating element. The light-emitting element includes at least one first conductive frame having at least one first electrically-conducting portion and at least one heat-dissipating portion, at least one second conductive frame adjacent to the first conductive frame and having at least one second electrically-conducting portion, a casing enclosing the first conductive frame and the second conductive frame, and at least one light-emitting chip disposed on the first conductive frame. The heat-conducting and electrically-insulating element includes a heat-conducting and electrically-insulating layer disposed on the heat-dissipating portion for insulating an electrical current from the heat-dissipating portion. Hence, the instant disclosure can plan a heat-conduction path and an electric-conduction path for the light-emitting chip to effectively increase the heat-dissipating efficiency of the light-emitting element due to the design of placing the heat-conducting and electrically-insulating layer on the heat-dissipating portion.

A lighting device includes a light source module and a housing mated to a heat sink and covered by a cover. The housing has a first shell portion encircled by an inner sidewall of the heat sink. Alternatively, the housing may further has a second shell portion arranged between the first shell portion and the inner sidewall of the heat sink. The respective ends of the first and second shell portions are covered by a first plate portion and a connecting portion. A cavity is defined by the first shell portion and the first plate portion for accommodating the light source module. A plurality of first thru-holes, second thru holes, third thru holes, fourth thru-holes, and fifth thru holes are formed on the circuit board, the connecting portion, the cover, the first shell portion, and the first plate portion, respectively.

A large-scale data processing system, a large-scale data processing method, and a non-transitory tangible machine-readable medium are provided. The large-scale data processing system comprises an interface and a processor. The interface accesses a multi-dimensional data model, wherein the multi-dimensional data model comprises a plurality of dimensions, the dimensions form a multi-dimensional space of measures, each dimension is a single space comprising a plurality of members with a common set of attributes, and each measure is a data element organized and accessible through the multi-dimensional space of the cross-product of all dimensions. The processor builds at least one Tree Object (TO), wherein the TO is derived by converting the multi-dimensional data model into an N-level tree data structure according to a level order of N attributes, each tree node in the TO meets all conditions of attributes for all ancestor nodes, and N is a positive integer.

A camera module of image processing and a method for integrating the camera module with a host are described. The camera module has a display control interface, an image sensor, and a camera control circuit. The display control interface is used to control at least one display module. The image sensor is used to capture image and provide image data signals. The camera control circuit is used to control the camera module. The camera module bypasses the display data signals of a host to display control modules according to a bypass signal. The camera module also performs image processing according to the bypass signal and a command set.

A device includes a cover defining a sleeve, which allows a transmission cable to pass therethrough such that the transmission cable passes from an inner side of the device to an outer side of the device. An elastomer is filled in the sleeve and embedded with the transmission cable. A fastening member is employed to engage with the sleeve to tightly press the elastomer embedded with the transmission cable to prevent water from entering the device along the transmission cable and the sleeve.
