Description

Technical Field

[0001] The utility model relates to the technical field of visual detection, in particular to an air-cooled light source device. Background Art

[0002] At present, market demand is getting higher and higher, and the requirements for visual light sources are also getting higher and higher. In some special environments, such as high temperature, high humidity and other external environmental factors, it is easy for electrical components such as light boards to corrode and age, and short circuit problems may occur. When conventional sealing is used to prevent corrosion and aging, the operating temperature of the light board will be too high, affecting the normal life of the light board. When ventilation and cooling are used, if the gas introduced does not contact the light source, the cooling effect will be poor. If it is in direct contact, the air will cause the light board to corrode and age. Utility Model Content

However, in the actual application of this application, this is not limiting.

[0045] like Figure 1-2 As shown, this embodiment provides an air-cooled light source device, which includes: a main body 110, a light source 120, a lampshade 130, a protective mechanism 140, a sealing mechanism 150, and a cooling mechanism 160. The light source 120 is installed in the main body 110 for emitting light; the lampshade 130 is disposed over the light source 120; the protective mechanism 140 is disposed on the light source 120 to provide a sealed surface protection for the light source 120; the sealing mechanism 150 is used to seal the light source 120; and the cooling mechanism 160 is used to cool the light source 120 components and isolate the light source 120 from the air. A channel 170 is formed between the light source 120 and the lampshade 130. The sealing mechanism 150 seals the channel 170, and the cooling mechanism 160 allows the inert gas in the channel 170 to flow from one side to the other. That is, when the air-cooled light source device 100 performs light source irradiation operation in a high-temperature environment, the sealing mechanism 150 isolates the light source 120 from the air, so that the light source 120 will not be corroded and aged due to contact with the air in a high-temperature and / or high-humidity environment, thereby ensuring the normal operation of the light source 120 and extending its life; at the same time, the sealing mechanism 150 can also seal the channel 170 to prevent the inert gas from overflowing, effectively ensuring cooling and wasting of inert gas resources; and by introducing flowing inert gas and directly acting on the light source 120, it can effectively achieve a cooling effect and can also further isolate the light source 120 from the air to prevent oxidation.

[0046] In this embodiment, the protective mechanism 140 includes a protective layer 141. Protective layer 141 covers the surface of light source 120 and isolates light source 120 from the air. This layer protects light source 120 from corrosion and aging. Protective layer 141 is made of conformal coating, which is applied to light source 120. Conformal coating provides excellent moisture-proof, corrosion-resistant, and aging-resistant properties for protecting circuit boards and related equipment.

[0047] like Figure 2-4 As shown, in this embodiment, the sealing mechanism 150 includes a sealing gasket 151 and a sealing strip 152. The lampshade 130 is mounted on the main body 110, and the sealing gasket 151 is mounted between the lampshade 130 and the main body 110; the sealing strip 152 is mounted between the light source 120 and the main body 110; the sealing gasket 151 and the sealing strip 152 seal the passage 170 on all sides. In other words, when the lampshade 130 is mounted on the main body 110, the sealing gasket 151 blocks the gap between the lampshade 130 and the main body 110, ensuring the tightness of the connection between the lampshade 130 and the main body 110, preventing air from infiltrating through the gap and causing corrosion and aging, and also preventing inert gas from escaping and wasting. The sealing strip 152 also prevents the formation of a gap between the light source 120 and the main body 110, preventing air from infiltrating through the gap and causing corrosion and aging, and preventing inert gas from escaping and wasting.

[0048] like Figure 3 As shown, in this embodiment, the cooling mechanism 160 includes an air inlet 161 and an air outlet 162. The air inlet 161 is provided at one end of the main body 110, and the air outlet 162 is provided at the other end of the main body 110; the air inlet 161 and the air outlet 162 are connected to the channel 170. When the inert gas enters through the air inlet 161, the inert gas flows to the air outlet 162 through the channel 170, and finally the inert gas is discharged through the air outlet 162. The use of the inert gas to flow can absorb heat in a timely manner, and the one-end entry and one-end discharge method is adopted, so that no dead corner of flow is formed in the entire air-cooled light source device 100, and the inert gas that has absorbed heat can be discharged in a timely manner, so that the cooling effect is better.

[0049] like Figure 2-3 As shown, in this embodiment, the air-cooled light source device 100 further includes a first air pipe connector 10a and a second air pipe connector 10b. The first air pipe connector 10a is mounted to the air inlet 161, and the second air pipe connector 10b is mounted to the air outlet 162. The first air pipe connector 10a is used to communicate with the inert gas inlet pipe, and the second air pipe connector 10b is used to communicate with the inert gas outlet pipe. Using connectors for installation makes installation more convenient.

[0050] like Figure 2-4As shown, in this embodiment, the light source 120 device further includes a sealing ring 10c. Sealing rings are installed in both the first air pipe connector 10a and the second air pipe connector 10b. When the air inlet 161 is installed with the first air pipe connector 10a, the sealing ring 10c seals the air inlet 161 with the first air pipe connector 10a; when the air outlet 162 is installed with the second air pipe connector 10b, the sealing ring 10c seals the air outlet 162 with the second air pipe connector 10b. The use of the sealing ring 10c to seal the air pipe connectors with the air inlet 161 and the air outlet 162 further prevents air from infiltrating into the main body 110, causing corrosion and aging of the light source, and further prevents the escape of inert gas, which can lead to waste.

[0051] In this embodiment, the distance between the lampshade 130 and the light source 120 is 65-75 cm, which can ensure that there is enough inert gas in the channel 170 to absorb heat, and also ensure that there is enough distance between the lampshade 130 and the light source 120 so that the light source 120 can achieve a good lighting effect through the lampshade 130.

[0052] In this embodiment, the light source 120 is a strip-shaped LED light panel. The lampshade 130 is a diffuser. The LED light panel and the lampshade 130 work together to make the emitted light more uniform, ensuring the smooth operation of the air-cooled light source device 100.

[0053] To sum up, the utility model provides an air-cooled light source device. The beneficial effects of the utility model are: the light source is initially sealed through a protective mechanism, and then the light source is directly contacted with the light source through the sealing mechanism and the introduction of inert gas, so that the light source is sealed for the second time, effectively preventing air and moisture from contacting the light source, ensuring that the light source will not be corroded and aged, and thus ensuring the service life of the light source; and when the flowing inert gas directly acts on the light source, the heat generated by the light source can also be taken away in time, ensuring the operational stability of the air-cooled light source device.
