Provided is an LED-type spotlight focused by lens adjustment; comprised are a heat sink (1), a heat sink front cover (2), a heat sink rear cover (3), an LED light source (4), a condenser lens (5), a telescoping front cylinder (6), a fixed rear cylinder (7), and a rotation adjustment ring (8). The LED light source (4) is mounted and fixed on the front end face of the heat sink (1); the heat sink front cover (2) is mounted and fixed on the front end part of the heat sink (1); the heat sink rear cover (3) is mounted and fixed on the rear end part of the heat sink (1). The fixed rear cylinder (7) is mounted and fixed on the front end part of the heat sink front cover (2); the telescoping front cylinder (6) is axially slidably fitted to the inner side of the fixed rear cylinder (7). The threaded ridge (10) on the outer wall of the telescoping front cylinder (6) is exposed through a through-groove (11) of the fixed rear cylinder (7); the rotation adjustment ring (8) is rotatably fitted on the fixed rear cylinder (7), and threadedly engages with the threads of the exposed threaded ridge (10) of the telescoping front cylinder (6). The condenser lens (5) is mounted and fixed on the front end part of the telescoping front cylinder (6). The present spotlight resolves the problems present in existing spotlights of low telescopic adjustment fineness of the telescoping front cylinder (6), large volume of the lamp, and complicated structures and assembly. |
