Abstract: A light-emitting diode (LED) lighting apparatus includes an exterior member which covers a heat-dissipating member. Therefore, the LED lighting apparatus may be dustproof and waterproof. The shape of the heat-dissipating member may be modified to increase the surface area thereof and thus effectively dissipate heat.

Abstract: Disclosed is a connector for preventing unlocking which includes a signal pin transferring a signal; a body into which the signal pin is inserted and which is electrically isolated from the signal pin; a first housing having a hollow portion into which one end of the body is inserted, a thread groove and at least one protruding portion or a plurality of fixing grooves formed at an inner circumferential surface of the other end thereof; and a second housing having a hollow portion into which the other body end is inserted and through which the second housing is moved along an outer circumferential surface of the body in an axial direction.

Abstract: A light emitting diode (LED) lighting module is provided including an LED array, and at least one of a diffusing portion and a reflecting portion. The LED array, equipped with at least one LED, may include a side wall which surrounds the at least one LED. The diffusing portion may be detachably coupled to the LED array and may include a diffusion plate which diffuses light emitted from the at least one LED The reflecting portion may be detachably coupled to one of the LED array and the diffusing portion and may reflect light emitted from the at least one LED. The LED array may be selectively coupled with the diffusing portion, the reflecting portion, or both the diffusing portion and the reflecting portion.

Abstract: A light-emitting device (LED) engine includes: a body having a through-hole; a light-emitting module that is disposed under the body, includes at least one light emitting device, and is disposed to expose a light-emitting surface via the through-hole; and a printed circuit board (PCB) which is disposed under the body, to which the light-emitting module is coupled, and includes a terminal unit for supplying power to the light-emitting module.

Abstract: An apparatus and method for automatically ordering medical goods in an electronic commerce site. The automatic medical goods ordering apparatus and method can automatically order medical goods from a medical goods provider using an electronic commerce site in order to smoothly supply medical goods which consumers desire. Namely, in order to smoothly supply medical goods which consumers desire to purchase, the automatic medical goods ordering apparatus and method are capable of previously checking a purchase quantity of medical goods and automatically ordering necessary medical goods from a provider of the medical goods and holding expected optimum stocks of the medical goods. As a result, the present invention is highly efficient in that the consumers such as hospitals and pharmacies can easily purchase the medical goods, and, on the other hand, it is possible to minimize economic loss due to maintaining unnecessarily large stocks of the medical goods.
