Abstract: An LED illuminating device includes a hollow base including a first end and a second end, an LED substrate, a connector, and a driving circuit module accommodated in the base. A plurality of vents are defined in a circumferential wall of the hollow base; a space is formed between a circumferential wall of the driving circuit module and the inner surface of the circumferential wall of the hollow base. The space can communicate with the plurality of vents and serve as a hot air channel, to promote heat exchange between hot air in the base and cool air outside the base.

Abstract: A receptacle terminal to be utilized in an electrical receptacle includes a first sidewall, a second sidewall, a connecting member, and a restricting member. The second sidewall cooperates with the first sidewall to define a receiving space to receive an electrical terminal. The connecting member connects the first sidewall to the second wall. The restricting member includes a first hook and a second hook. The first hook extends from one end of the first sidewall. The second hook extends from one end of the second sidewall. An end of the first hook and an end of the second hook are spaced from each other. When the electrical terminal is received in the receiving space, the first hook engages with the second hook, to prevent the receiving space from being stretch beyond a predetermined size or size range.

Abstract: An LED illuminating device comprises a housing with a base plate, a prism sheet and a circuit board. The prism sheet is mounted in the housing and comprises a number of V-shaped micro-grooves formed along two directions intersecting with each other. A plurality of LED units are arranged on the circuit board in groups, each group comprises four LED units, the four LED units totally emitting light of three colors. Two adjacent groups share a LED unit. Four virtual mixed light sources are formed by reflection of the prism sheet to the circuit board. Each of the virtual mixed light sources forms a desired color different from the colors of the light emitted from the LED units.

The prism sheet is mounted in the housing and comprises a number of V-shaped micro-grooves formed thereon along two directions intersecting with each other. A plurality of LED units are arranged in groups on the circuit board. Each LED illuminating group comprises three LED units. Each of the LED units emits light of a color different from those of the other two LED units. Four virtual mixed light sources are formed by the reflection of the prism sheet to the circuit board when the light emitted by a particular LED unit mixes with light emitted by adjacent LED units on the circuit board. Each of the virtual mixed light sources forms a desired color different from the colors of the light emitted from the LED units.
