Abstract

The present invention relates to an LED light bulb having a centralized light source with forward cooling and can be used as a replacement bulb. The LED light bulb (300) of the present invention comprises a light source (340) having first and second LED modules (343, 345) arranged and mounted on opposite sides of a support block (334) such that a uniform lighting including up and down lights can be provided. As the light source (340) and the support block (334) are physically arranged toward the front portion of the light bulb and as conducive structures (332, 336) are provided to extend directly in front of the light source (340), heat originated from the light source (340) is effectively and efficiently dissipated to the ambient utilizing the space and structures configured at the front portion of the light bulb.
