Abstract
Description
Technical Field
[0001] The present application relates to the field of LED lamps, and in particular to an oil-filled eye-lubricating lamp and a lamp. Background Art
[0002] LED lamps, or light emitting diodes, are lighting devices that use solid-state semiconductor materials to generate light. LED lamps have been widely used in many fields due to their high efficiency, low power consumption, long durability, and environmental friendliness. In the prior art, the blue light chips used in LED lamps produce strong short-wave blue light and are unable to filter out some of the short-wave blue light, which can cause harm to customers' eyes.
[0003] Fluoride phosphors are phosphors with fluoride as the matrix material. Fluoride phosphors usually have high luminescence quantum efficiency, can emit strong fluorescence, and can maintain stable fluorescence performance at high temperatures, so they are very suitable for fluorescence detection in high temperature environments. However, fluoride phosphors have relatively poor weather resistance, especially in humid environments, they are easy to decompose, resulting in a serious decrease in their luminescence performance. This problem limits the application of fluoride phosphors under certain environmental conditions. Summary of the invention
[0004] In view of this, the present application provides an oil-filled eye-soothing lamp and a lamp to reduce the generation of LED lamp glare and short-wave blue light.
[0005] In a first aspect, the present application provides an oil-filled eye lubricating lamp, which comprises: a shell; oil filled in the shell; a light-emitting component immersed in the oil, the light-emitting component comprising an LED light source, and the LED light source uses fluoride phosphor as the fluorescent material.
[0006] In a second aspect, the present application further provides a lamp, comprising: a main body, and an oil-filled eye-lubricating lamp arranged on the main body.
[0007] In summary, the present application adopts fluoride phosphor as the fluorescent material of the LED light source and fills it with oil. The oil can diffusely reflect the light at 360°, so that the light is evenly distributed and the generation of glare is reduced. At the same time, the oil-filled eye-lubricating lamp can also reduce the generation of short-wave blue light of the LED lamp and reduce the harm to the user's eyes due to the use of fluoride phosphor. In addition, the oil can also dissipate the heat of the LED light source, which can improve the heat-resistant performance of the LED fluoride phosphor, thereby making the oil-filled eye-lubricating lamp have a better service life.

[0034] Please see Figure 1The present application provides a lamp 100, which can be a garden lamp, a bedroom lamp, a screen lamp, etc. The lamp 100 is installed on the wall of a building, such as a roof, a wall, etc., to illuminate the space where the building is located. The lamp 100 can also be a detector lamp, a flashlight, etc., which does not need to be installed on the building surface, but can be moved as a mobile light source to facilitate users to carry and use. The lamp 100 includes a main body 1, and an oil-filled eye-lubricating lamp 2 arranged inside the main body 1. The lamp 100 provides lighting for the working environment through the oil-filled eye-lubricating lamp 2 to ensure that normal work can still be performed under poor light conditions.
[0035] Please see Figure 2 , Figure 2 The structure of the oil-filled eye-lubricating lamp 2 is shown. The oil-filled eye-lubricating lamp 2 includes a shell 20, oil 21, and a light-emitting component 22. In this embodiment, the oil 21 is filled in the shell 20, and the light-emitting component 22 is immersed in the oil 21. The shell 20 is used to seal the oil 21 and the light-emitting component 22 together and prevent leakage of the oil 21. The oil 21 is used to filter the short-wave blue light present in the oil-filled eye-lubricating lamp 2. The light-emitting component 22 is used to convert electrical energy into light energy and emit bright light. The light-emitting component 22 is electrically connected to the power supply. When the light-emitting component 22 is powered on, the light-emitting component 22 generates light, and the light is transmitted to the outside of the shell 20 through the oil 21.
[0036] The following will specifically describe the composition and working principle of each component of the oil-filled eye-soothing lamp 2, as well as the coordinated work between the components, so as to describe in detail how the oil-filled eye-soothing lamp 2 specifically reduces short-wave blue light.
[0037] Please see Figure 3 In the first embodiment, the oil-filled eye-lubricating lamp 2 is a light bulb. The shape of the light bulb is oval, round, etc. The shell 20 of the light bulb is a closed structure made of transparent epoxy resin or silicone. The shell 20 includes a body 200 and a head 201. One end of the body 200 is provided with an opening 202, and the head 201 is arranged at the opening 202 of the body 200. The opening 202 fits the connection of the head 201 and is sealed together by an oil-resistant sealant, so that the body 200 and the head 201 form a closed structure containing an internal space 23, and the oil 21 is filled in the internal space 23. In some feasible embodiments, the connection between the body 200 and the head 201 can also be achieved by providing a thread on the inner wall of one between the connection of the body 200 and the connection of the head 201, and providing a bayonet that matches the thread on the other, and applying a sealant at the threaded connection, so that the body 200 and the head 201 are threadedly sealed. Among them, the sealed connection between the body 200 and the head 201 includes but is not limited to the use of sealant connection and threaded sealing connection.
[0038] The oil 21 fills the internal space 23, accounting for 90% of the internal space 23, and the remaining 10% of the internal space 23 is used as an air cavity to place the air discharged by the oil 21. The boiling point of the oil 21 is 600°C. In this embodiment, the oil 21 uses dimethyl silicone oil with a viscosity of 50. When configuring the liquid, the dimethyl silicone oil with a viscosity of 50 is added to the vacuum stirring tank with a heating function, and then the dimethyl silicone oil 21 is heated to 90°C and stirred for 30 minutes. The dimethyl silicone oil 21 can diffusely reflect the LED light at 360°, so that the light distribution is more uniform, thereby reducing the generation of glare to prevent the light emitted by the oil-filled eye-moistening lamp 2 from being dazzling. In some feasible embodiments, the oil 21 can also be methyl silicone oil, ethyl silicone oil, and methylethoxy silicone oil. In this embodiment, the present application uses high-temperature resistant silicone oil to completely wrap the LED light source, so that the light source and the phosphor can be effectively isolated from the air and water molecules, avoiding the problem of hydrolysis of the fluoride phosphor.
[0039] The light-emitting component 22 is immersed in the oil 21. The light-emitting component 22 includes an LED light source 220. The LED light source 220 uses a fluoride phosphor 221 as a fluorescent material. The shape of the LED light source is cylindrical, spherical, etc. In this embodiment, the fluoride phosphor 221 is added during the manufacturing process of the LED light source 220. When the LED light source 220 is powered on, the fluoride phosphor 221 optimizes the spectral distribution to make the light emitted by the LED light source 220 more uniform and soft, thereby indirectly reducing the harm of the short-wave blue light component. Among them, optimizing the spectral distribution is to achieve the optimization of the spectral distribution of the LED by accurately controlling the type, concentration and distribution of the fluorescent material of the fluoride phosphor 221 during the manufacturing process of the LED light source 220. For example, by adjusting the type and concentration of the doped rare earth ions, the functions of the LED light source 220 such as multi-color luminescence and adjustable color temperature can be realized. This optimization makes the light emitted by the LED light source 220 more uniform and reduces the excessive concentration of the short-wave blue light component. Immersing the light-emitting component 22 in the oil 21 can remove the heat generated by the LED light source 220 during operation through the thermal conductivity of the oil 21, thereby reducing the temperature of the LED light source 220 and preventing the LED light source 220 from being easily damaged due to the heat-intolerant fluoride phosphor 221. At the same time, the risk of the LED light source 220 being corroded or damaged can be reduced, especially in harsh environments, such as high temperature, high humidity, corrosion, etc., the protective effect of the oil 21 on the LED light source 220 is more significant.
[0040] Please see Figure 4, a schematic diagram of the structure of the light strip provided in the second embodiment of the present application. In the second embodiment, the oil-filled eye-lubricating lamp 2 is a strip light strip. The difference between the first embodiment and the second embodiment lies in the structure of the shell 20, and the light strip in the second embodiment further includes a substrate 3, the substrate 3 is sealed in the shell 20, and the light-emitting component 22 is arranged on the substrate 3. The following is a detailed description of the differences between the second embodiment and the first embodiment.
[0041] In this embodiment, the housing 20 includes two semicircular aluminum profiles 205 and two semicircular outer covers 203. The aluminum profiles 205 are provided with inner grooves 204 at both ends close to the semicircular diameter, and the outer covers 203 are provided with convex parts 206 at both ends close to the semicircular diameter. The convex parts 206 and the inner grooves 204 are plugged together to form a fixed structure, and the above two fixed structures are symmetrically spliced to form a complete circular structure. Among them, the joint of the convex parts 206 and the inner grooves 204 is coated with sealant to prevent leakage of the oil 21. The substrate 3 divides the internal space 23 of the housing 20 into a first space 230 and a second space 231. The oil 21 is arranged in the first space 230, and the side of the substrate 3 provided with the light-emitting component 22 is arranged in the first space 230, and the side of the substrate 3 facing away from the light-emitting component 22 is arranged in the second space 231. In some feasible embodiments, a plurality of air holes 30 are provided at the edge of the substrate 3, and the air holes 30 are used to discharge the air mixed with the oil 21. Specifically, the air mixed in the oil 21 diffuses from the first space 230 of the substrate 3 where the light-emitting component 22 is provided to the second space 231 of the substrate 3 away from the light-emitting component 22 through the air holes 30. Expelling the air mixed in the oil 21 through the air holes 30 can improve the light-emitting effect of the oil-filled eye-lubricating lamp 2. The shapes of the aluminum profile 205 and the outer cover 203 and the splicing relationship between the two can be set according to actual needs and are not limited here.
[0042] Please see Figure 5 , a schematic diagram of the structure of a light strip provided in the third embodiment of the present application. The difference between the third embodiment and the second embodiment lies in the shape of the light strip. In the third embodiment, the oil-filled eye-lubricating lamp 2 is an annular light strip. Specifically, the shell 20 of the annular light strip 2 is annular, and the substrate 3 disposed inside the shell 20 is annular. The annular substrate 3 divides the internal space 23 of the shell 20 into a first space 230 and a second space 231.
[0043] Please see Figure 6 , a schematic diagram of the structure of the light strip provided in the fourth embodiment of the present application. The difference between the fourth embodiment and the third embodiment lies in the shape of the light strip. In the fourth embodiment, the oil-filled eye-lubricating lamp 2 is a triangular light strip. Specifically, the shell 20 of the triangular light strip 2 is triangular, and the substrate 3 disposed inside the shell 20 is triangular. The triangular substrate 3 divides the internal space 23 of the shell 30 into a first space 230 and a second space 231.
[0044] It can be understood that the shapes of the light strip 2 in the above embodiments are merely examples. In each embodiment, while ensuring that the internal space 23 of the shell 20 is divided into the first space 230 and the second space 231, the shapes of the shell and the substrate, and the combination of the shell and the substrate can be selected as needed and are not limited here.
[0045] Please see Figure 7 In some feasible embodiments, the oil-filled eye-lubricating lamp 2 also includes a radiator 5 and a thermal conductive layer 6. The radiator 5 is disposed between the two inner grooves 204, and the side of the radiator 5 facing the first space is fixed to the substrate 3 by a fixing member, and there is a small gap between the radiator 5 and the substrate. A plurality of heat sinks 50 are provided on the side of the radiator 5 facing the second space to increase the heat dissipation area of the radiator 5. The thermal conductive layer 6 is located between the radiator 5 and the substrate to fill the above-mentioned gap. Among them, the thermal conductive layer 6 is made of thermal conductive silicone grease. The LED light source 220 generates heat when working, and the heat is transmitted to the radiator 5 through the thermal conductive layer 6 with high conductivity. The addition of the radiator 5 and the thermal conductive layer 6 to the oil-filled eye-lubricating lamp 2 can further accelerate the dissipation of the heat generated by the LED light source 220 when working.
