CN201297606Y - Lamp tube end cover with respirator - Google Patents

Abstract

The utility model discloses a novel take fluorescent tube end cover of respirator, including the end cover body, be equipped with the drying zone on the end cover body, built-in drier, the drying zone communicates with each other ventilative with the fluorescent tube is inside and outside. Because the drying area is arranged in the end cover and the drying agent is arranged in the end cover, the water vapor entering the interior of the lamp tube from the outside can be absorbed, and the interior of the lamp tube is kept dry; meanwhile, the drying area is communicated with the inside and the outside of the lamp tube for ventilation, heat generated by the lamp tube during working can be dissipated through the end cover, moisture absorbed by the drying agent is exhausted, the drying agent is dried again, and the moisture absorption performance is continuously kept, so that the lamp tube is similar to a breathing state and is called as the lamp tube end cover with a respirator.

Description

Lamp tube end cap with respirator

technical field

The utility model relates to an end cover in a lamp tube, in particular to a lamp tube end cover with a respirator.

Background technique

Existing guardrail lights or other lighting tubes have end caps at both ends, or plugs. Although the end caps are generally sealed end caps, the sealing performance of the existing end caps is not good after assembly, and the humidity or moisture in the air is very high. It is easy to enter the inside of the lamp tube, accelerate the aging of electronic components in the lamp tube, or even short-circuit, shortening the service life of the lamp; at the same time, due to the use of sealed end caps, the lamp tube that uses a fuse lamp or a high-power LED lamp as the light source is in operation. The large amount of heat generated is not easy to dissipate, causing the temperature of the device to rise continuously as the working time increases, affecting the life of the lamp. Therefore, faced with such a dilemma, it is necessary to prevent external moisture from invading the inside of the lamp tube through the end cap, and to ensure that the lamp tube has good heat dissipation.

Therefore, it is necessary to develop a new type of lamp tube end cover that is not only convenient for use and maintenance, but also can ensure that the moisture or moisture in the air is not easy to enter the inside of the lamp tube, and at the same time facilitate the heat dissipation in the lamp tube, so as to meet the growing market needs. .

Utility model content

The technical problem to be solved by the utility model is to overcome the above-mentioned defects and provide a new type of lamp tube end cover with a respirator, which can prevent external water vapor from entering the inside of the lamp tube through the end cover, and at the same time make the lamp tube produce The heat dissipates as quickly as possible.

The utility model is realized through the following technical solutions:

The utility model relates to a lamp tube end cover with a respirator, which includes an end cover body, a drying area is arranged on the end cover body, and a desiccant is installed inside, and the drying area communicates with the inside and outside of the lamp tube.

The drying area includes a drying area cover and a drying area box, both of which have ventilation holes. The drying area box accommodates the desiccant, and the drying area cover is closed with it.

Both the drying area cover and the drying area box are circular in cross section.

It also includes a sealing ring, the sealing ring is placed inside the end cover body, and the sealing ring is provided with a vent hole at a position corresponding to the drying area.

The end cover body is provided with a lead wire hole, and the position corresponding to the sealing ring is provided with a wire passing hole.

Screw holes are provided on the end cover body, and nail holes are provided at corresponding positions on the sealing ring.

The beneficial effect of the utility model is that, since the drying area is set in the end cover, the built-in desiccant can absorb the water vapor entering the inside of the lamp tube from the outside, and keep the inside of the lamp tube dry; The heat generated at the time can be dissipated through the end cover, and the moisture absorbed by the desiccant is discharged, so that the desiccant returns to dryness and continues to maintain the hygroscopic performance, which is similar to a breathing state, so it is called the lamp tube end with a respirator. build.

Detailed ways

Preferred embodiments of the present utility model are described according to the above-mentioned drawings.

In this embodiment, the lamp tube end cap includes an end cap body 1 , a sealing ring 2 and a drying area 3 . The drying area 3 includes a drying area box 31 and a drying area cover 32. The drying area cover 32 is fastened on the drying area box 31, and a desiccant is housed in it. Both the drying area box 31 and the drying area cover 32 have vent holes 33. The size is smaller than the diameter of the desiccant. There are lead wire holes 11 and screw holes 12 on the end cover body 1. The lead wire holes 11 have the same shape as the lead wires, and the size is equal to the size of the lead wires. There are two or more screw holes 12. A preferred solution of this embodiment is two screw holes. 12. The sealing ring 2 has a wire hole 21, a nail hole 22 and a vent hole 23. The shape of the wire hole 21 and the nail hole 22 are respectively the same as the lead hole 11 and the screw hole 12, and the size is smaller than the size of the lead hole 11 and the screw hole 12. , the ventilation hole 23 is circular, and its diameter is smaller than the cross-sectional diameter of the drying zone box 31 . During the operation, put the desiccant in the drying area 3, put the sealing ring 2 into the back of the end cover body 1, make the wire passing hole 21, the nail passing hole 22 and the air hole 23 connect with the lead wire hole 11, the screw hole 12 and the air hole 23 respectively. Correspond to the drying area cover 32, then pass the lead wire through the lead wire hole 11 and the wire passing hole 21, and finally pass the screw through the screw hole 12 and the nail passing hole 22, and the lamp tube end cover can be fixed on the lamp tube.

What is disclosed above is only the preferred embodiment of the present utility model, and of course the scope of rights of the present utility model cannot be limited with this. Therefore, the equivalent changes made according to the patent scope of the utility model still belong to the scope covered by the utility model .
