Temperature differences can even occur on the exterior surface, causing expansion and contraction, leading to cracks. Frequent maintenance and replacement of sealed lamp light sources increases operating costs and impacts customer experience. Summary of the Invention

[0004] The purpose of the utility model is to improve the problem that the existing sealed lamp cannot handle oily gas (impurities), and to provide a sealed lamp.

[0005] The technical solutions to achieve the above objectives include the following:

[0006] A sealed lamp includes: a shell, an adsorbent, a filter cover, and a light source. A mounting cavity is formed in the shell. The filter cover is installed in the shell and divides the mounting cavity into a first chamber and a second chamber. The light source is installed in the second chamber.

[0008] The adsorption component is arranged between the air inlet and the inner wall of the shell.

[0009] In one embodiment, the air outlet direction of the fan intersects with the air inlet direction of the fan, and the adsorption element is arranged in the air inlet direction.

[0010] In one embodiment, the fan has two air inlets, which are arranged opposite to each other.

[0014] In one embodiment, the sealed lamp further has a heat sink, which is installed in a shell. The shell has a heat dissipation hole, and the heat dissipation hole is arranged outside the first cavity. The first end of the heat sink is connected to the first cavity, and the second end of the heat sink is connected to the heat dissipation hole.

[0015] In one embodiment, a sealing ring is provided between the heat dissipation element and the housing, and the sealing ring is used to seal the opening of the first chamber.

[0032] Research has found that the reason why the outer surface of the light source 4 is easily stained with oil is because the sealed lamp 100 has good sealing performance, and the light source 4 will generate a certain temperature when it emits light. This temperature will cause the components in the shell 1 of the sealed lamp 100 to volatilize and produce oily gas. The oily gas cannot diffuse outside the sealed lamp 100, so that the oily gas diffuses to the outer surface of the light source 4. The oily gas is affected by the high temperature and will adhere to the outer surface of the light source 4, thereby causing stains on the outer surface of the light source 4.

[0033] For this purpose, the present invention proposes a sealed lamp 100. Figures 1 to 4 As shown, it includes a shell 1, an adsorbent 2, a filter screen cover 3, and a light source component 4. An installation cavity is formed in the shell 1. The filter screen cover 3 is installed in the shell 1, and the installation cavity is divided into a first chamber 11 and a second chamber 31. The light source component 4 is installed in the second chamber 31. The filter screen cover 3 has multiple filter holes. The first chamber 11 is connected to the second chamber 31 through the filter holes. The adsorbent 2 is installed in the first chamber 11. Specifically, the filter screen 3 is disposed within the mounting cavity, separating the mounting cavity into a first chamber 11 and a second chamber 31. The second chamber 31 is used to house the light source 4. When the light source 4 is illuminated, the high temperature it generates causes the components within the housing 1 to generate oily gas (impurities). The oily gas (impurities) evaporate and become free within the first chamber 11 of the housing 1. The oily gas (impurities) diffuse within the first chamber 11 of the housing 1. The filter holes of the filter screen 3 are used to block the oily gas (impurities) from diffusing from the first chamber 11 to the second chamber 31, preventing the oily gas (impurities) from adhering to the light source 4 in the second chamber 31, thereby preventing the light source 4 from affecting its luminous efficiency and increasing its service life. The adsorbent 2 is used to adsorb the oily gas, preventing it from adhering to the filter screen 3 and the inner wall 12 of the housing 1, thereby improving the problem that the existing sealed lamp 100 cannot handle the oily gas (impurities).

[0034] In some embodiments, as Figure 4 As shown, the sealed lamp 100 also includes a fan 5, which is installed within the housing 1. The fan 5's air outlet 51 faces the light source 4, and the fan 5's air inlet 52 is disposed away from the inner wall 12 of the housing 1. A certain gap exists between the air inlet 52 and the inner wall 12 of the housing 1, and the adsorbent 2 is disposed between the air inlet 52 and the inner wall 12 of the housing 1. Specifically, the airflow velocity through the fan 5's air outlet 51 is relatively high, increasing the air flow velocity on the outer surface of the light source 4, causing the hot air on the outer surface of the light source 4 to circulate within the housing 1. As the hot air passes through the inner wall 12 of the housing 1, it exchanges heat with the air outside the housing 1 through the housing 1, thereby dissipating heat from the light source 4 of the sealed lamp 100. Furthermore, the fan 5 accelerates the air flow velocity within the housing 1, causing the oily gas to quickly flow to the adsorbent 2 and be adsorbed by it.

[0035] In some embodiments, the air outlet direction of the fan 5 intersects with the air inlet direction of the fan 5, and the adsorption member 2 is arranged in the air inlet direction. Figure 4 It can be seen that the air outlet direction of the fan 5 is toward the light source component 4. After the airflow blown out by the fan 5 passes through the light source component 4, it diffuses on the inner wall 12 of the outer shell 1 and flows back to the air inlet 52 of the fan 5. The air outlet direction and the air inlet direction set in this way make the air in the outer shell 1 form an internal circulation; and the adsorption component 2 is set in the air inlet direction, so that when the oily gas is driven by the airflow, the oily gas flows to the adsorption component 2 and is further adsorbed by the adsorption component 2.

[0036] Preferably, the fan 5 has two air inlets 52, which are arranged opposite to each other. Specifically, by arranging two opposite air inlets 52, the air near the inner wall 12 on both sides of the housing 1 can be continuously sucked into the fan 5, and then blown out from the air outlet 51 of the fan 5. Figure 4 From the perspective of the embodiment, the air circulation range within the shell 1 basically covers the space and position within the shell 1, and the air within the shell 1 forms a larger range of circulation, so that more cold air in the shell 1 can exchange heat with the air near the light source 4, further improving the heat exchange efficiency of the sealed lamp 100.

[0037] Preferably, Figure 2 As shown, the adsorbent 2 is mounted on the inner wall 12 of the housing 1 and comprises activated carbon. Specifically, activated carbon is a carbonaceous material with a black appearance and a well-developed internal pore structure, resulting in a large surface area. Furthermore, the carbon particles contain even smaller pores called capillaries. These capillaries possess a strong adsorption capacity. Due to the large surface area of ​​the carbon particles, the surface area of ​​the micropores per gram of activated carbon material can be expanded to 800-1500 square meters, and this is even higher for specialized applications. In other words, the internal surface area of ​​the micropores in a typical activated carbon particle can be equivalent to the size of a living room. It is precisely this highly developed pore structure, similar to that of human blood vessels, that gives activated carbon its excellent adsorption properties. Therefore, in the local environment within the housing 1, due to the mutual attraction between molecules, when one molecule is captured by the inner pores of the activated carbon and enters, more molecules are attracted due to the mutual attraction until the inner pores of the activated carbon are completely filled. Therefore, when these oily gases (impurities) hit the capillary tube, they are adsorbed, the adsorption speed is fast, the air purification effect is good, and the oily gases in the first chamber 11 are further adsorbed.

[0038] In some embodiments, the sealed lamp 100 is suitable for use in stage and cultural tourism applications using high-pressure gas discharge bulbs, LEDs, or lasers. During the production process, activated carbon must be sealed within the lamp as soon as it is installed to prevent it from adsorbing the activated carbon upon contact with the outside air. The activated carbon has a finite saturation period.

[0039] Preferably, the activated carbon 2 is arranged away from the light source 4. Specifically, the adsorption capacity of the activated carbon will decrease at high temperatures, and even desorption will occur, resulting in its inability to effectively adsorb odors and toxic substances; therefore, the adsorption effect of the activated carbon will decrease as the temperature rises. In order to extend the service life of the activated carbon and ensure its effectiveness, it should be avoided from being exposed to high temperatures for a long time; in addition, the activated carbon should be stored in a dry, ventilated and light-proof environment to avoid moisture and direct sunlight. In this embodiment, the sealed lamp 100 is not turned on for 24 hours, and is generally only turned on at night. Therefore, placing the activated carbon in a ventilated environment can further improve its adsorption capacity.

[0040] Preferably, at least part of the filter cover 3 is made of a transparent material. Specifically, since the filter cover 3 wraps the light source 4, the transparent material allows the light source 4 to emit light normally and prevents the light emitted by the light source 4 from being blocked by the filter cover 3.

[0041] In some embodiments, as Figure 1 and Figure 3 As shown, the sealed lamp 100 further includes a heat sink 6, which is mounted within the housing 1. The housing 1 is provided with a heat dissipation hole 13, which is disposed outside the first chamber 11. A first end of the heat sink 6 communicates with the first chamber 11, and a second end of the heat sink 6 communicates with the heat dissipation hole 13. Specifically, the heat sink 6 can be a copper sheet heat sink. Heat from the first chamber 11 is transferred to the heat sink 6, which then transfers the heat within the first chamber 11 to the heat dissipation hole 13 for dissipation. This achieves heat exchange between the inside and outside of the housing 1, further improving the heat dissipation efficiency of the sealed lamp 100.

[0042] Preferably, a sealing ring (not shown) is provided between the heat sink 6 and the housing 1 to seal the opening of the first chamber 11. Specifically, the sealing ring is used to seal the opening of the first chamber 11, thereby preventing moisture from entering the first chamber 11 through the gap between the heat sink 6 and the housing 1, thereby improving the waterproof effect of the sealed lamp 100.

[0043] In some embodiments, as Figure 1As shown, the housing 1 includes a first shell 101 and a second shell 102, which are sealed together. The first shell 101 or the second shell 102 has a perspective surface 103, and the light source 4 is arranged on one side of the perspective surface 103; the perspective surface 103 of the first shell 101 or the second shell 102 is made of a transparent material. Specifically, the housing 1 is composed of the first shell 101 and the second shell 102, which facilitates the installation of components, the filter cover 3, the light source 4, the fan 5, the heat sink 6, etc. in the second shell 102, and then the first shell 101 and the second shell 102 are sealed together. The first shell 101 and the second shell 102 have a perspective surface 103, which is used to diffuse the light emitted by the light source 4 outside the housing 1 and illuminate the surrounding environment.

[0044] It should be noted that in this sealed lamp 100, by disposing a filter screen 3 within the housing 1 and separating the chambers of the housing 1, the light source 4 is disposed in the second chamber 31 and the adsorbent 2 is disposed in the first chamber 11. This improves the problem of existing sealed lamps 100 being unable to handle oily gases (impurities). Other sealed lamps 100 that utilize the filter screen 3 and adsorbent 2 within the housing 1, or that dispose the light source 4 and adsorbent 2 in two different chambers, are also within the scope of protection of this application.

[0045] When quoting drawing descriptions, new features that appear are described; in order to avoid repeated quoting of drawings which would result in a less concise description, features that have been described clearly will not be quoted from the drawings one by one.

[0046] The purpose of the above embodiments is to exemplify and deduce the technical solution of the utility model, and to fully describe the technical solution, purpose and effect of the utility model. Its purpose is to enable the public to have a more thorough and comprehensive understanding of the disclosed content of the utility model, and it does not limit the scope of protection of the utility model.

[0047] The above embodiments are not exhaustive of the present invention, and there may be many other embodiments not listed. Any replacements and improvements made without violating the concept of the present invention are within the scope of protection of the present invention.
