一个点光是发光源，它从单个点发出照明。根据点光的 PointLight.Range ，发光的球体是圆形的。
为了使 PointLight 提供照明，它必须是 BasePart 或 Attachment 的直接子级 (部分或附件本身必须是 Workspace 的后代)。
如果有一个 PointLight 是父级到零件，那么灯会从零件的 BasePart.Position 发出。 如果有一个 PointLight 是父级到附件，那么灯会发出从附件的 Attachment.WorldPosition 。

代码示例
This example creates a new anchored BasePart named Part at the position {0, 0, 0}.
It then creates a new point light with brightness of 1, Color3 color of {255/255, 255/255, 255/255} (white) and range of 16 studs. The point light's parent is set to the BasePart we created. To view the light, navigate to the part at {0, 0, 0} or move the Part created to a location visible to the player.
Please note that the properties of the created point light can easily be changed by modifying the property values in the code sample below. Additionally, if you have an existing point light, you can also create a similar script that modifies that light instead of creating a new BasePart and light.
local part = Instance.new("Part")
part.Anchored = true
part.Position = Vector3.new(0, 0, 0)
part.Parent = workspace
local light = Instance.new("PointLight")
light.Color = Color3.new(1, 1, 1)
light.Brightness = 1
light.Range = 16
light.Parent = part
