Abstract
A LED lamp cup includes a heat-conducting substrate, a LED unit, a casing and a light-transmitting lamp cover. The casing can be detachably assembled with the heat-conducting substrate or the light-transmitting lamp cover easily. Further, the casing or the light-transmitting lamp cover is configured that it can be retained from outside toward inside, so that the casing may not rotated reversely after being assembled with the heat-conducting substrate or the light-transmitting lamp cover. Thus, the biasing force exerted on the first and second waterproof gaskets may not be reduced to enlarge the gap. Thus, the penetration of moisture can be prevented to achieve a good waterproof effect.
