LED BULB LAMP CAPABLE OF WIDE ANGLE LIGHT EMISSION

摘要

This invention publishes a kind of LED bulb lamp which can realize large-angle irradiance, including LED, radiator and lampshade. The said radiator consists of two parts, with the lower part connecting with the lamp base of the light fitting, the upper part being in a shape of prismatic table with multiple sides which has a top smaller than the bottom. The angle between the prismatic sides of the prismatic table and the perpendicular centerline of the light fitting is 10°‰¤¸‰¤25°. The two upper and lower parts of the radiator are connected between each other. On the said prismatic sides, at least one LED is installed. The upper part of the said radiator is provided in the lampshade. This invention can expand the lights in a range of irradiance with a small angle to the most area of the bulb to have an omni-directional light distribution effect with the requirements of irradiance characteristics and heat-dissipation efficiency being considered concurrently.
