在Threejs中，光源用Light表示，它是所有光源的基类。它的构造函数是：
THREE.Light ( hex )
它有一个参数hex，接受一个16进制的颜色值。例如要定义一种红色的光源，我们可以这样来定义：
Var redLight = new THREE.Light(0xFF0000);
Three.js内置了多种光源可以直接调用：
- AmbientLight（环境光）
- AreaLight（区域光）
- DirectionalLight（平行光）
- HemisphereLight（半球光）
- PointLight（点光源）
- SpotLight（聚光灯）

现在运行页面，我们只能看到蓝色的背景和一块黑色的几何体，因为我们还没有加入灯光，所以一切的物体都是黑色的。立方体和地面的材质均为MeshLambertMaterial（类似纸张，可以均匀反射接收到的光线）。
