LED LAMP EMITTING EVEN LIGHT

摘要

A LED lamp emitting even light. The LED lamp comprises a lamp body and a lamp holder (6) connected with two ends of the lamp body. A power supply (5) is provided between the lamp body and the lamp holder (6). The lamp body comprises a light diffusion cover (1) and a heat-dissipation casing (2) engaged with each other to form a lamp cavity (8). The heat-dissipation casing (2) is provided with a substrate (3), and the substrate (3) is provided a light emitting diode (4). The maximum distance between the light emitting diode (4) and the light diffusion cover (1) is larger than 50% of the total height of the lamp body. Because the power supply (5) is no longer provided inside the heat-dissipation casing (2) but outside the heat-dissipation casing (2), a large accommodation space is not required to be reserved at the heat-dissipation casing (2) to mount the power supply (5), so that the height of the substrate (3) is reduced, and therefore the distance between the light emitting diode (4) and the light diffusion cover (1) is increased, the overlapping area of lighting of adjacent light emitting diodes is increased, and therefore, the evenness of LED lamp lighting is improved.
