Embodiment 1

[0024] according to Figure 1 to Figure 5 As shown, a fully sealed lamp described in this embodiment includes a transparent cover tube 3, respectively fixedly connected to the end seats 2 at both ends of the cover tube 3, and an end cover 1 that is sealed and connected to each end seat 2. The lamp tube 4 and the drive circuit in the closed space formed by the cover tube 3, the end seat 2, and the end cover 1, and the wire seal 7 arranged on an end cover 1, the drive circuit is separately arranged on two circuit boards 6 Above, the two circuit boards 6 are respectively located in the two end seats 2 , and the two circuit boards 6 are respectively provided with electrical jacks 61 which are mated with the lamp caps of the lamp tube 4 . The outer wall of the end base 2 is provided with external threads, the end cover 1 and the end base 2 are connected by threads, and a sealing rubber ring is arranged between the end base 2 and the end cover 1 . The end seat 2 is also provided wi...

Embodiment 2

[0034] Such as Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the lamp tube radial positioning ring 23 and the connecting rod 24 are not provided in the end seat, the circuit board 6 is circular, and its diameter is equivalent to the inner diameter of the end cover 1, and the end cover 1. An elastic stopper 11 is provided at a corresponding position on the inner periphery. After the end cover 1 is screwed onto the end seat 2, the circuit board 6 is clamped between the end seat 2 and the elastic stopper 11.

Abstract

The invention discloses an all-sealed lamp comprising a transparent covering tube, end seats, end caps, a lamp tube, driving circuits and a lead sealing element. The end seats are fixedly connected to two ends of the covering tube respectively, each end cap is hermetically connected with each end seat, the lamp tube and the driving circuits are arranged in an enclosed space formed by the covering tube, the end seats and the end caps, and the lead sealing element is arranged on one end cap. The driving circuits are arranged on two circuit boards separately, the two circuit boards are located in the two end seats respectively, and electrical jacks matched with lamp caps of the lamp tube in insertion are formed in the two circuit boards respectively. Thus, components of an independent lamp holder and conventional lamp tube end seats are omitted, space of the positions of the end seats and the end caps is utilized fully, components specially used for mounting the driving circuits are omitted, the all-sealed lamp is few in parts and assembly procedures, and production cost is lowered on the basis that sealing performance is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of lighting lamps, and in particular relates to a fully sealed lamp. Background technique [0002] Due to the harsh environment of workshops such as water jet loom workshops, the lighting system in the workshop needs better sealing performance to ensure good waterproof, dustproof and corrosion resistance. In order to achieve the above performance, some lamp tubes in the prior art are generally realized by installing a sealed shell outside the ordinary lamp tube, but often due to the complicated structure or improper sealing method, the installation, replacement, maintenance and cleaning of the lamp tube are often caused. trouble. For example, the Chinese patent "fully enclosed long-tube fluorescent lamp" whose publication number is CN202419278U, its disclosed technical solution is to install the lamp consisting of a lamp tube, a lamp tube end seat and a lamp tube seat connected to the lamp tube end seat on ...
