Abstract

The present invention relates to an embedded light that increases heat dissipation speed, comprising a heat-dissipative inner casing of a receiving chamber having an opening facing downward, an LED light-emitting device received in the receiving chamber, a heat-dissipative outer casing sleeved on and abutted against the outer edge of the heat-dissipative inner casing, and a heat-dissipative covering frame arranged inside the heat-dissipative outer casing. The heat-dissipative covering frame is also sleeved on and abutted against the outer edge of the heat-dissipative inner casing. Due to the heat-dissipative outer casing and the heat-dissipative covering frame being directly and tightly sleeved on the heat-dissipative inner casing, thermal energy of the LED light-emitting device can be dissipated through the heat-dissipative outer casing and the heat-dissipative covering frame that are exposed under a ceiling and provided with improved air ventilation. As such, lumens decay of the LED light-emitting device resulting from overheat can be avoided and thus lifespan of the LED light-emitting device can be extended.
