Example 1

Referring to fig. 1-5, an anti-condensation luminaire, comprising: the lamp comprises a lamp body 1, a light-transmitting piece 2 and a blocking piece, wherein the light-transmitting piece 2 is arranged on the lamp body 1, a light source cavity is formed between the lamp body 1 and the light-transmitting piece 2, an exhaust hole 3 is formed in the cavity wall of the light source cavity, and the blocking piece can seal or open the exhaust hole 3. It should be noted that, the cavity wall of the light source cavity is provided with the air vent 3, that is, the air vent 3 may be located on the light-transmitting member 2 or may be located on the lamp main body 1, and in this embodiment, the air vent 3 is located on the light-transmitting member 2.

In this embodiment, the lamp body 1 is provided with a concave, and the light-transmitting member 2 is plate-shaped and covers the concave, thereby forming a light source cavity. In other embodiments, the light-transmitting member 2 may be in a box shape with an opening at the lower side, and the light-transmitting member 2 is fastened on the lamp body 1 to form a light source cavity. Of course, there are various forming modes of the light source cavity, and the forming mode of the light source cavity is not limited in the present utility model, so long as the light source cavity is formed.

In this example, the anti-condensation principle of the anti-condensation lamp is as follows: before the ageing test, the vent hole 3 can be opened through the plugging piece to the lamps and lanterns, thereby when the ageing test, the steam in the light source chamber can be discharged to outside through the vent hole 3, after the ageing test, can be rapidly sealed through the plugging piece with the vent hole 3, avoid outside steam to get into the light source intracavity again. Therefore, the water vapor in the light source cavity is removed, and the external water vapor cannot enter again, so that the water vapor is prevented from generating condensation in the light source cavity. In addition, the condensation is avoided through the mode, the existing assembly process is not required to be changed, and high manufacturing labor hour cost is not generated.

In this embodiment, the light-transmitting member 2 is preferably a glass plate. Of course, the light-transmitting member 2 may be made of a suitable material, such as an acrylic plate, according to practical production requirements.

In this embodiment, the plugging member comprises a locking member 4, a sealing gasket 5 and a connecting post 6, the connecting post 6 is arranged on the cavity wall of the light source cavity, the locking member 4 can be locked or released from the outside through the vent hole 3 and the connecting post 6, and the locking member 4 is suitable for pressing the sealing gasket 5 to seal the vent hole 3 when locking with the connecting post 6; specifically, the locking member 4 is a screw, a threaded hole in threaded fit with the screw is formed in the connecting column 6, and the sealing washer 5 is sleeved on the screw. In the actual use process, when the exhaust hole 3 needs to be opened, the screw can be unscrewed, so that the light source cavity is directly connected with the outside through the exhaust hole 3; when the vent hole 3 needs to be sealed, the screw can be screwed on the connecting column 6, and the sealing gasket 5 can be extruded at the moment, so that the sealing of the vent hole 3 is realized by being matched with the screw.

In this embodiment, in order to reduce the influence of the vent hole 3 on the light emitting effect of the lamp, the vent hole 3 may be provided at the edge of the light transmitting member 2.

In this embodiment, the connection post 6 is disposed on the lamp body 1, and the threaded hole on the connection post 6 is coaxial with the exhaust hole 3. By the arrangement mode, the influence on the light emitting effect of the lamp can be further reduced, namely, only the vent hole 3 is required to be formed in the light transmitting piece 2, and no shielding is caused by other structures. In addition, in actual production, the lamp main body 1 is generally a plastic piece, and the connecting post 6 is arranged on the lamp main body 1, so that the lamp main body 1 can be conveniently produced, namely, the connecting post 6 and the lamp main body 1 can be molded at one time through a die.

In this embodiment, in order to ensure the sealing effect of the light source cavity, the light-transmitting member 2 and the lamp main body 1 may be bonded by sealant.
