Light-emitting diode (LED) lighting device capable of condensing light and dissipating heat

The invention provides an LED lighting device capable of condensing light and dissipating heat. The problems that an existing LED filament lamp is poor in heat dissipation capacity, low in light utilization rate, high in energy consumption and the like are solved. The lighting device body is a glass lampshade, the glass lampshade is divided into a bowl-shaped condensation opening and a cylindrical shell, an annular groove is formed in the connecting position of the bowl-shaped condensation opening and the cylindrical shell, a transparent and tough support is arranged in the groove, a lamp filament is fixed through a round hole in the support, and the lamp filament is connected with a lamp holder through a wire. According to the glass lampshade, through the design of the light gathering opening with the front opening and the rear opening and the columnar shell, the purposes of reducing light waste, having the light gathering function and the illumination area expanding function and enhancing the heat dissipati
