can not update THREE.DirectionalLight's direction

The DirectionalLightShadow always lookAt Vector3(0,0,0).

I set its direction below, but it not works. The light.shadow.camera always lookAt (0,0,0)

var light = new THREE.DirectionalLight(0xffffff, 1)
light.position.set(20,0,20)
light.lookAt(new THREE.Vector3(400,400,400))
light.castShadow = true

here is my code on codepen:
