Abstract
The invention discloses a brightness-adjustable lamp. The brightness-adjustable lamp comprises a fixed bracket and a light source fixed on the fixed bracket, and further comprises an inner lamp housing and an outer lamp housing, wherein the inner lamp housing covers the light source, and is fixed with the fixed bracket; the outer lamp housing covers the inner lamp housing, and is rotationally arranged on the fixed bracket; multiple first light through holes are formed in the inner lamp housing; multiple second light through holes are formed in the outer lamp housing; and the second light through holes can be respectively aligned to the first light through holes in the process of rotating the outer lamp housing relative to the inner lamp housing. When the brightness is adjusted in the use of the lamp, the outer lamp housing is driven to rotate relative to the inner lamp housing; and the larger the overlapped areas of the first light passing holes and the second light passing holes are, the more light rays of the light source are irradiated outside the lamp, and the illuminating brightness of the lamp is greater. Therefore, even if a general light source does not have a resistance adjusting function, the brightness of the lamp can be adjusted only by rotating the outer lamp housing. The invention provides the lamp with novel structure, low cost and simple structure.
