		<a target="THREE_Examples" href="../examples/#webgl_lights_spotlight">View in Examples</a><br />
		<h2>其他例子</h2>

		<div>[example:webgl_lights_spotlights lights / spotlights ]</div>

		<h2>代码示例</h2>
		<code>
		var spotLight = new THREE.SpotLight( 0xffffff );
		spotLight.position.set( 10, 10, 10 );
		scene.add( spotLight );

		var spotLightHelper = new THREE.SpotLightHelper( spotLight );
		scene.add( spotLightHelper );
		</code>


		<h2>构造函数</h2>


		<h3>[name]( [param:SpotLight light], [param:Hex color] )</h3>
		<p>
			[page:SpotLight light] -- 被模拟的聚光灯 [page:SpotLight] . <br /><br/>

			[page:Hex color] -- (可选的) 如果没有赋值辅助对象将使用光源的颜色.
		</p>


		<h2>属性</h2>
		<p>请到基类 [page:Object3D] 页面查看公共属性.</p>

		<h3>[property:LineSegments cone]</h3>
		<p>用于模拟光源的 [page:LineSegments] 类型对象.</p>

		<h3>[property:SpotLight light]</h3>
		<p>被模拟的聚光灯 [page:SpotLight] .</p>

		<h3>[property:object matrix]</h3>
		<p>请参考聚光灯的世界矩阵 [page:Object3D.matrixWorld matrixWorld].</p>

		<h3>[property:object matrixAutoUpdate]</h3>
		<p>
			请查看 [page:Object3D.matrixAutoUpdate]. 这里设置为 *false* 表示辅助对象
			使用聚光灯的 [page:Object3D.matrixWorld matrixWorld].
		</p>

		<h3>[property:hex color]</h3>
		<p>
			构造函数中传入的颜色值. 默认为 *undefined*. 如果改变该值,
			辅助对象的颜色将在下一次 [page:.update update] 被调用时更新.
