Patent attributes
A projection device includes a first light-emitting component, a second light-emitting component and a housing. The first light-emitting component and the second light-emitting component are fixed to the housing. A first outer surface of the housing is provided with a first light outlet and a second light outlet; the first light-emitting component is arranged corresponding to the first light outlet; the second light-emitting component is arranged corresponding to the second light outlet; and the first light outlet has a larger area than the second light outlet, such that a projection range of the second light-emitting component is within that of the first light-emitting component. The disclosure can avoid the defect of a single effect of a lamp cap of a projection lamp in the scope of the prior art.
