A detection device includes a substrate, a light-emitter, and a light receiver. The substrate includes a first surface area and a second surface area, in which the first surface area has a first reflectance greater than a second reflectance of the second surface area. The light emitter is disposed on the first surface area, and the light receiver is disposed on the second surface area. The light receiver has a third reflectance which is substantially the same as the second reflectance of the second surface area.

Detection device

An illuminating device including a substrate, a light-emitting diode element disposed on the substrate, an electrode element, and a sealing ring. The substrate has a groove, and the electrode element has a retaining slot disposed in the groove. The sealing ring is embedded into the retaining slot and a part of the groove to tightly fix the electrode element on the groove.

Illuminating device

A leadframe includes two spaced apart conductive legs, each of which includes a base section, and a first extension section extending from a bottom end of the base section in a direction away from the other one of the conductive legs. At least one of the conductive legs further includes a second extension section that extends from a top end of the base section thereof in the same direction as the first extension section for fixing the light-emitting diode chip. The heat generated by the light-emitting diode chip can be dissipated through a shortest heat-dissipating route, thereby increasing the heat-dissipating rate.
