Abstract
The invention relates to a bulb with a good heat dissipating effect. The bulb comprises a lamp holder, a plastic lamp base and a light permeating bulb shell, wherein the lamp holder, the plastic lamp base and the light permeating bulb shell are connected in sequence. A heat dissipater of which a through hole is formed in the center is connected in the plastic lamp base. The lower portion of the heat dissipater is inserted into the lamp holder and the outer side of the heat dissipater is in slight interference fit with the inner side of the lamp holder. The upper end of the heat dissipater is located in the light permeating bulb shell and an LED pasting sheet light source is arranged on the face of the upper end of the heat dissipater. A drive power supply is arranged in the through hole of the heat dissipater. According to the bulb, a structure of connecting the heat dissipater and the lamp holder is adopted, the lamp holder is in full contact with the heat dissipater and thus, the heat generated by the light source can be rapidly and effectively transmitted to the lamp holder through the heat dissipater. Heat generated by the light source can be in direct contact with the outside air to form effective convection heat dissipation. The heat dissipating effect is good and the aims of rapidly dissipating the heat and cooling the light source are achieved. The service life of the light source is effectively prolonged and the bulb is safe and reliable in use, attractive in appearance and high in practicability.
