A kind of watertight light fitting with light shade and light frame is provided. The exterior surface of the shade wall is even and smooth and inside the shade is installed an annular waterproof lining. The exterior edge side of the waterproof liner matches well with the interior side of the shade wall. A barrier wall stretches out from around the surface of the waterproof lining toward the light frame. The barrier wall keeps a certain distance to the exterior edge side of the waterproof lining. The barrier wall, together with the upper surface of the waterproof lining and the shade wall, forms a watertight groove. A watertight gasket is fixed inside the groove. The benefit of the waterproof lining with the watertight groove being formed partly by the waterproof lining is that the shade wall is fairly thin without requiring an outstretched step on the exterior surface of the shade wall. This reduces the raw material for producing the light shade as well as the weight of the shade. As a result, the product quality is ensured with decreased manufacturing defects and the cost is lower. In addition, the light fitting is aesthetically pleasing.

What is claimed is: 1. A watertight light fitting comprising: a light shade including an exterior surface that is even and smooth, and an annular waterproof lining within the light shade, wherein an exterior edge side of the waterproof lining matches well with an interior side of the light shade; a light frame including a barrier wall that stretches out and around a surface of the waterproof lining away from the light frame, the barrier wall being located a fixed distance from the exterior edge side of the waterproof lining, wherein the barrier wall, together with an upper surface of the waterproof lining and the shade, forms a watertight groove to retain a watertight gasket having a thickness greater than the depth of the groove; glass plate located on the watertight gasket such that the glass plate presses against the watertight gasket; and a protruding flange stretching out from around the interior side of the light shade, wherein the protruding flange has a barrier stretching out toward the light frame and the glass plate is installed between the light shade and the light frame. 2. The watertight light fitting as claimed in claim 1 wherein the shade wall and the waterproof lining form a u-shaped groove to retain the watertight gasket. 3. The watertight light fitting as claimed in claim 2 wherein the barrier wall closes the u-shaped groove to form the watertight groove to retain the watertight gasket. 4. A watertight light fitting comprising: a light shade including an exterior surface that is even and smooth and an annular waterproof lining within the light shade, wherein an exterior edge side of the waterproof lining matches with an interior side of the light shade; and a light frame including a barrier wall that stretches out and around a surface of the waterproof lining away from the light frame, the barrier wall being located a fixed distance from the exterior edge side of the waterproof lining, wherein the barrier wall, an upper surface of the waterproof lining, and the shade wall form a watertight groove to retain a watertight gasket, wherein there is a protruding flange on the surface of the light frame at the joint with the waterproof lining such that the protruding flange is adapted to stretch into the watertight groove and press against the watertight gasket. 5. The watertight light fitting as claimed in claim 4 wherein the shade wall and the waterproof lining form a u-shaped groove to retain the watertight gasket. 6. The watertight light fitting as claimed in claim 5 wherein the barrier wall closes the u-shaped groove to form the watertight groove to retain the watertight gasket. 7. A watertight light fitting comprising: a light shade including an exterior surface; an annular waterproof lining within the light shade, wherein an exterior edge side of the waterproof lining matches with an interior side of the light shade; and a light frame including a barrier wall that stretches out and around a surface of the waterproof lining away from the light frame, the barrier wall being located a fixed distance from the exterior edge side of the waterproof lining, wherein the barrier wall, an upper surface of the waterproof lining, and the shade wall form a watertight groove to retain a watertight gasket, wherein three or more underpinnings stretch out from around the interior side of the shade wall and the waterproof lining is fixed with screws upon the underpinnings inside the light shade. 8. The watertight light fitting as claimed in claim 7 wherein the light frame and the light shade coincide with each other at the exterior edge of the joint. 9. The watertight light fitting as claimed in claim 7 wherein the shade wall and the waterproof lining form a u-shaped groove to retain the watertight gasket. 10. The watertight light fitting as claimed in claim 9 wherein the barrier wall closes the u-shaped groove to form the watertight groove to retain the watertight gasket.
