Abstract
The invention relates to a shading light and compensating light device of a lamp house with an internal lamp. The device is an opacity body that is set between the lamp tube and the arc light plate of the lamp house. The opacity body comprises a left reflecting light portion, a right reflecting light portion and a shading light portion. The cross section of the shading light portion is arc. The left reflecting light portion and the right reflecting light portion are symmetrical with each other. The plane of symmetry of the left reflecting light portion and the right reflecting light portion is on the same plane with the central line of the lamp tube. The shading light portion can shade the light which beats on it, so that the light can shoot out from the front and two sides of the lamp tube. So the device can reduce the loss of the light, so as to enhance the illuminance of the lambency plate of the lamp house. The left reflecting light portion and the right reflecting light portion can compensate light to the portion of the lambency plate which is far from the lamp tube, so as to make illuminance on the lambency plate uniform.
