Waterproof wall washer

Abstract

The invention provides a waterproof wall washer. The washer comprises a long-strip lamp frame, the front portion of the lamp frame is provided with a vertically through cavity in a length direction, an illuminating light body is arranged in the cavity, a front sealing cover of the cavity is provided with a light guide plate, the upper and lower ends of the lamp frame are provided with side pressure covers for sealing the end of the cavity, the side pressure covers comprise sealing blocks which are clamped into the cavity and a cover plate covering the end portion of the lamp frame, and a sealing rubber ring which is in contact with the cavity and the inner side wall of a light guide plate and is clamped in the cavity together with the sealing block is arranged between the sealing block andthe cover plate; the sealing rubber ring which is in contact with the cavity and the inner side wall of the light guide plate and is clamped in the cavity together with the sealing block, and the sealing rubber ring is completely in contact with the cavity and the inner side wall of the light guide plate, thereby solving the technical problem that a machining error causes that the rubber ring cannot be completely in contact with the lamp frame and the light guide plate and achieving complete sealing of the cavity and ensuring the liquid sealing effect of the whole lamp and improving the service life thereof.

Description

[0001] 【Technical field】 [0002] The invention relates to a waterproof wall washer lamp. [0003] 【Background technique】 [0004] The traditional wall washer is generally composed of a lamp frame and a light guide plate. The lamp frame is provided with a cavity for placing the light source, and the two ends of the lamp frame are provided with a cover plate for sealing the cavity. In order to realize waterproof, the cover plate There is an annular groove on the top, and an annular rubber ring is arranged on the annular groove to seal the connection between the lamp frame and the end face of the light guide plate. However, due to processing errors, the end face of the lamp frame may be uneven, or the length of the light guide plate may be uneven. Inconsistent with the length of the light frame, the end face of the light guide plate is not flush with the end face of the light frame. In these cases, the annular rubber ring on the cover cannot ensure complete contact with the end f...

[0004] The traditional wall washer is generally composed of a lamp frame and a light guide plate. The lamp frame is provided with a cavity for placing the light source, and the two ends of the lamp frame are provided with a cover plate for sealing the cavity. In order to realize waterproof, the cover plate There is an annular groove on the top, and an annular rubber ring is arranged on the annular groove to seal the connection between the lamp frame and the end face of the light guide plate. However, due to processing errors, the end face of the lamp frame may be uneven, or the length of the light guide plate may be uneven. Inconsistent with the length of the light frame, the end face of the light guide plate is not flush with the end face of the light frame. In these cases, the annular rubber ring on the cover cannot ensure complete contact with the end face of the light frame and the light guide plate, especially When the length of the light guide plate is shorter than the length of the light frame, the annular rubber ring cannot contact the light guide plate at all, resulting in water leakage points that cannot guarantee the sealing of the wall washer. It is prone to water leakage after being exposed to rain, wind and rain, which will cause the light source to be easily damaged and not have a long service life.
