HIGHLY EFFICIENT HEAT-DISSIPATING LIGHT-EMITTING DIODE LIGHTING DEVICE
The present disclosure provides a light-emitting diode (LED) lighting device. The LED lighting device includes a lamp base, a glass shell, a heat-dissipating cup, a driving power source, an LED light source module, and an optical portion. The LED light source module, the heat-dissipating cup, and the driving power source are arranged from top to bottom inside the glass shell. A top portion of the glass shell is connected to the optical portion and a bottom portion of the glass shell is connected to the lamp base. The heat-dissipating cup faces upwardly and an outer sidewall of the heat-dissipating cup forms a close contact with an inner sidewall of the glass shell. The LED light source module is fixed within the heat-dissipating cup. The driving power source is positioned under the heat-dissipating cup and a space is formed between the driving power source and the heat-dissipating cup.
CIRCUIT BOARD AND IMAGE FORMING APPARATUS
The circuit board has a surface mount LED with a lens on the circuit board. A conductive portion and remaining space in the periphery of the LED are covered with solid copper foil so that reflectance of light and a heat dissipation effect are enhanced. In addition, layer structures between the circuit board and an assembled component are the same between contact portions with the assembled component so that tilt in mounting the board is suppressed. As a result, the circuit board having mounted thereon the surface mount LED having high directivity can be accurately mounted on the assembled component, tilt of an optical axis can be suppressed, the reflectance of light from the LED can be increased, and the heat dissipation effect can be enhanced.
