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.

Light-emitting diode lamp with an improved leadframe

The present invention discloses a light emitting element including a carrier, at least one light emitting chip, an adhesive and a first encapsulated layer. The light emitting chip is fixed onto the carrier by the adhesive, and most of the carrier and adhesive are made of a light absorbing material, so that the external luminescence quantum efficiency of the light emitting element is poor. The invention adopts a first encapsulated layer disposed on the carrier to cover the light absorbing material including the adhesive or carrier, so as to reduce the light absorption and improve the external luminescence quantum efficiency of the light emitting element.

Light emitting element

LED package carrier

An LED including housing, lead frame in the housing, light-emitting chip, and packed colloid; pit accommodation portion being disposed in the housing to expose lead frame, and multiple reflective sidewalls at various inclinations being disposed on a side of accommodation portion; the chip being disposed on a lead frame; streams of light form the chip traveling in different directions when reflected by those sidewalls; and most of those streams of light being emitted out of the accommodation portion to promote luminance performance of the LED.
