The invention relates to the field of LED, and in particular relates to a novel LED down lamp. The novel LED down lamp is mainly formed by combining a lamp cup (10), a bracket (5) and a reflection cup (1); the lamp cup (10) is connected with the bracket (5); the bracket (5) is connected with the reflection cup; the lamp cup (10) is detachably connected with the bracket (5). The novel LED down lamp is nice in appearance; the reflection cup is provided with a simple interchange mode that the reflection cup can be easily, simply and safely replaced without any tools; the lamp is of a die set structure, and the power can be replaced while a die set is changed; a screwing structure is adopted for fixing, so that the replacement is simple; COB lamp beads are used, and the explicit reference is more than 80, which is far more than that of common lamp, and therefore, the colors of an object can be shown, and as a result, the object can be more realistic.
