The spotlight generally includes a lamp cap and a lampshade. The lamp cap is provided with a circuit structure. The front end of the lamp cap is provided with a luminous body. The front side of the lamp cap is surrounded by a lampshade. Light is reflected forward. Common illuminant light sources are scattered light sources with poor condensing properties. Therefore, a convex lens can be set on the front side of the lampshade of the spotlight to condense the light emitted by the light source to form a beam. The convex lens is generally made of glass. In addition, the light source of the spotlight can be a single white light source, or it can be a variable color light source with multiple lamps. The cost of the color changing light source is much higher than that of a single white light source. There is also a single white light source. The color-changing spotlight of this kind of spotlight has too many front-end structures and is inconvenient to use.
