Embodiment Construction

[0008] Depend on figure 1 It can be seen that it is the general assembly drawing of the end cover of the sealing tube of the lamp of this embodiment. The drive circuit installation structure of the fully sealed lamp consists of O-ring 1, rear cover 2, rear cover ring groove surface 3, lamp shell 4, lamp shell guide column 5, lamp shell hole column 6, lamp shell small platform, lamp shell round The ring surface 8 and the self-tapping screw 9 are composed. The O-ring 1 is set on the back cover 2, so that the ring groove surface 3 of the back cover is in contact with the O-ring 1, and the back cover 2 is installed on the lamp housing 4 along the guide column 5 of the lamp housing. , the lamp shell small platform 7 on the lamp shell 4 is in contact with the lamp shell annular surface 8, the self-tapping screw 9 is tapped into the lamp shell hole column 6, and the O-ring 1 is compressed and deformed to realize the sealing of the lamp. The O-ring is a national standard O-ring, with...

Abstract

A drive circuit mounting structure of a full sealed lamp is composed of an O-type ring, a rear cover, a rear cover ring groove face, a lamp housing, a lamp housing guide column, a lamp housing hole column, a lamp housing small platform, a lamp housing ring face and a self-tapping screw. The O-type ring is arranged on the rear cover in a sleeving manner, the rear cover ring groove face is in contact with the O-type ring, and the rear cover is mounted on the lamp housing along the lamp housing guide column. The drive circuit mounting structure is characterized in that the lamp housing small platform on the lamp housing is in contact with the lamp housing ring face, the self-tapping screw is tapped into the lamp housing hole column, a rear cover and lamp housing combination face is pressed, the O-type ring is compressed to deform, and lamp sealing is achieved. According to the drive circuit mounting structure, a circuit board is located between the outer end of an end seat and an elastic check block, and the circuit board and a lamp tube are both fixed. Therefore, the number of components of the full sealed lamp is small, few assembly procedures are needed, and the production cost is reduced on the basis of guaranteeing the sealing performance.

Description

technical field [0001] The invention relates to a drive circuit installation structure of a fully sealed lamp. Background technique [0002] Landscape lighting installed on the bottom of the water must first solve the problem of high sealing, no water leakage and no water seepage; at the same time, because the pressure in the water increases with the increase of depth, the sealing problem of the high pressure on the bottom must be overcome. Some lamps in the prior art are generally realized by adding a sealed shell outside the common lamp, but the installation, replacement, maintenance and cleaning of the lamps are often troublesome due to complicated structures or improper sealing methods. For example, the Chinese patent with publication number CN202419278U "Totally Enclosed Long Tube Fluorescent Lamp", the disclosed technical solution is to install a lamp composed of a lamp tube, a lamp tube end base and a lamp tube base connected to the lamp tube end base to a transparent...
