[0020] In one possible implementation, the side of the light-transmitting cover close to the second through hole is connected to the first plate, and the side of the light-transmitting cover away from the second through hole is connected to the second plate, a cavity is formed between the first plate, the second plate and the light-transmitting cover, and the fill light assembly is located in the cavity.

In a night vision environment (dark light), the fill light assembly emits infrared light, and the reflective assembly reflects the infrared light to the light-transmitting cover, so that the infrared light is emitted from the light-transmitting cover more evenly. After receiving the infrared light, the objects in the environment reflect the infrared light to the lens module, so that the lens module obtains an image of the environment. Since the fill light assembly does not directly emit infrared light to the light-transmitting cover, but the reflective assembly guides the infrared light to the light-transmitting cover, the infrared light will be emitted from the light-transmitting cover in a more dispersed manner. As a result, the brightness of the infrared light emitted by the camera is lower, which is not easily perceived by the human eye, and is therefore less likely to cause a red burst phenomenon, thereby improving the concealment of the camera.

DETAILED DESCRIPTION

[0055] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0057] At night or in dim light, the camera uses infrared light to fill in the shooting environment to obtain clearer images.

[0058] like Figure 1 In the related art, a camera includes a housing 1, a light shield 2, a lens module 3, and a fill light assembly 4. The lens module 3 and fill light assembly 4 are located within the housing 1, and the light shield 2 is connected to the housing 1. The light shield 2 is located in the outgoing light path of the fill light assembly 4. The fill light assembly 4 emits infrared light perpendicularly toward the light shield, allowing the infrared light to be transmitted to the outside of the light shield.

[0059] However, the camera in the related art is prone to produce a redburst phenomenon when emitting infrared light, that is, the human eye will see red light, thereby reducing the concealment of the camera.

[0060] Related art typically uses 850nm infrared light for fill light. The shorter the wavelength of the infrared light, the more pronounced the redburst phenomenon, and the higher the sensitivity of the lens module 3. Therefore, to improve the redburst problem, current manufacturers use 940nm infrared light for fill light. However, the lens module's sensitivity to 940nm infrared light is lower than that to 850nm infrared light, which reduces the camera's fill light effect. Therefore, to achieve the same fill light brightness for 940nm and 850nm infrared light, a larger current must flow through the fill light assembly 4, which reduces energy efficiency and causes the fill light assembly 4 to generate significant heat, thereby adversely affecting the overall performance of the camera.

[0061] In view of the above technical problems, the present disclosure provides a camera, such as Figure 2 and Figure 3 As shown, the camera includes a housing 1, a light-transmitting cover 2, a lens module 3, a fill light assembly 4, and a reflective assembly 5. The housing 1 has a first through hole 11. The light-transmitting cover 2 is located in the first through hole 11 and is connected to the housing 1. The light-transmitting cover 2 has a second through hole 21. The lens module 3 is located inside the housing 1 and is opposite to the second through hole 21. The fill light assembly 4 surrounds the lens module 3 and is used to emit infrared light. The reflective assembly 5 is located inside the housing 1 and is located on the output light path of the fill light assembly 4. The reflective assembly 5 is used to reflect the infrared light emitted by the fill light assembly 4 toward the light-transmitting cover 2.

[0062] The light-transmitting cover 2 has a relatively high infrared light transmittance (above 80%) and a relatively low visible light transmittance (below 5%). When the infrared light is emitted along the normal direction of the light-transmitting cover 2, the illumination intensity of the infrared light is the highest.

[0063] The technical solution provided by the embodiment of the present disclosure is provided with a reflective component 5 inside the shell 1. When the camera is in a night vision environment (dark light), the fill light component 4 emits infrared light, and the reflective component 5 reflects the infrared light to the light-transmitting cover 2, so that the infrared light is emitted from the light-transmitting cover 2 more evenly. After the objects in the environment receive the infrared light, they reflect the infrared light to the lens module 3, so that the lens module 3 obtains an image of the environment. Since the fill light component 4 does not directly emit infrared light to the light-transmitting cover 2, but the infrared light is guided to the light-transmitting cover 2 by the reflective component 5, the infrared light will be emitted from the light-transmitting cover 2 in a more dispersed manner. As a result, the brightness of the infrared light emitted by the camera is lower, and it is not easily detected by the human eye, so it is not easy to cause the red burst phenomenon, thereby improving the concealment of the camera.

[0064] In this way, the fill light assembly 4 can still use 850nm infrared light for fill light. Since the lens module 3 has a high sensitivity to 850nm infrared light, the structure described in the present invention can not only use 850nm infrared light for fill light, but also solve the red burst problem of 850nm infrared light.

[0065] In related technologies, such as Figure 1 As shown, the fill light assembly 4 in the camera is usually arranged toward the light shield 2, so that the light emitted by the fill light assembly 4 is perpendicular to the light shield 2. However, the light intensity is strongest when the light is emitted in the normal direction, and the stronger the infrared light is, the more likely it is to produce red burst phenomenon. For this reason, the embodiment of the present disclosure changes the light emission direction of the fill light assembly 4. In some examples, such as Figure 4 and Figure 8 As shown, the fill light assembly 4 includes a light board 41 and a plurality of fill lights 42. Figure 5 As shown, the light board 41 is annular and surrounds the lens module 2 , and a plurality of fill lights 42 are fixed to the outer wall of the light board 41 and are evenly distributed along the circumference of the light board 41 .

[0066] The fill light 42 emits infrared light radially from the light board 41, so that the infrared light does not strike the light shield 2 perpendicularly. Instead, it is reflected by the reflective assembly 5 and directed toward the light shield 2 from multiple angles. The intensity of the light is strongest when it is emitted in the normal direction, and decreases as it travels further away from the normal direction. Therefore, by emitting infrared light from multiple angles toward the light shield 2, the intensity of the infrared light when it exits the light shield 2 is reduced, thus preventing the occurrence of red burst.

[0067] After the fill light assembly 4 emits infrared light, how the reflective assembly 5 evenly reflects the light to the transparent cover 2 is the key to preventing the camera from generating red burst.

[0068] An implementation of the reflection component 5 is exemplarily described below.

[0069] In some examples, such as Figure 5 and Figure 6 As shown, the reflective assembly 5 includes a reflective plate 51. The reflective plate 51 surrounds the fill light assembly 4, wherein the reflective plate 51 is made of a highly reflective material for infrared light, so that the reflective plate 51 can reflect more infrared light and avoid energy loss of infrared light caused by the reflective plate 51 absorbing infrared light.

[0070] After the fill light 42 of the fill light assembly 4 emits infrared light, the inner side of the reflective plate 51 reflects the infrared light, so that the infrared light can be evenly emitted from the transparent cover 2 .

[0071] In some examples, such as Figure 6 and Figure 7 As shown, the reflective plate 51 includes a first plate body 511 and a second plate body 512. Figure 5As shown, the first plate 511 is annular and surrounds the lens module 3. The second plate 512 is bent relative to the first plate 511 and connected to the end of the first plate 511 away from the light-transmitting cover 2. The second plate 512 surrounds the first plate 511. The fill light assembly 4 is located between the first plate 511 and the second plate 512, with the second plate 512 surrounding the fill light assembly 4. The first plate 511 and the second plate 512 can be an integral structure. The first plate 511 is used to support the second plate 512 and the light board 41 of the fill light assembly 4, and the second plate 512 is used to reflect the infrared light emitted by the fill light 42.

[0072] In some examples, the second plate 512 is arc-shaped in its longitudinal section, where the longitudinal section of the second plate 512 coincides with the central axis of the lens module 3. This facilitates the second plate 512 to reflect light from all angles toward the light shield 2, thereby reducing the intensity of light emitted from the light shield 2 and making the light more uniformly emitted from the light shield 2, thereby reducing the occurrence of red burst.

[0073] In some examples, such as Figure 5 As shown, the side of the light-transmitting cover 2 close to the second through hole 21 is connected to the first plate 511, and the side of the light-transmitting cover 2 away from the second through hole 21 is connected to the second plate 512. A cavity 50 is formed between the first plate 511, the second plate 512, and the light-transmitting cover 2, and the fill light assembly 4 is located in the cavity 50. As a result, the infrared light emitted by the fill light assembly 4 is completely reflected in the cavity 50, preventing infrared light leakage and energy loss.

[0074] In some examples, the first plate 511 is an aluminum plate. Aluminum has a high infrared reflectivity, preventing infrared light absorption and light loss caused by the first plate 511. Furthermore, aluminum has excellent heat dissipation. When the fill light assembly 4 is in operation, the fill light 42 generates heat and transfers it to the light board 41. The light board 41 can fit tightly against the first plate 511, effectively dissipating heat from the first plate 511. Furthermore, aluminum is lightweight, so the first plate 511 does not increase the weight of the camera.

[0075] Of course, in other examples, the first plate 511 may also be made of other materials with high infrared light reflectivity and good heat dissipation, such as copper, iron, etc.

[0076] In some examples, the camera further includes a heat conducting component located between the first plate 511 and the fill light assembly 4. When the fill light assembly 4 is in operation, the fill light 42 generates heat, and the heat conducting component can transfer the heat of the fill light assembly 4 to the first plate 511, thereby reducing the temperature of the fill light assembly 4.

[0077] Next, another implementation of the reflective component 5 is exemplarily described.

[0078] In some examples, such as Figures 9-11 As shown, the reflective assembly 5 includes a light guide 52. The light guide 52 is annular and surrounds the fill light assembly 4. The light guide 52 has an inner wall 521, an outer wall 522, a bottom wall 523, and a top wall 524. The bottom wall 523 and the outer wall 522 are used to reflect infrared light emitted by the fill light assembly 4 to the top wall 524, and the top wall 524 is used to transmit the infrared light to the light-transmitting cover 2. The bottom wall 523 is the side wall of the light guide 52 away from the light-transmitting cover 2, the top wall 524 is the side wall of the light guide 52 close to the light-transmitting cover 2, and the top wall 524 is the light-emitting surface of the light guide 52.

[0079] The light guide 52 can reflect and refract the light, converting the point light source into a surface light source, thereby making the light more evenly emitted from the light-transmitting cover 2 and reducing the light intensity when the light is emitted from the light-transmitting cover 2, thereby avoiding the red burst phenomenon.

[0080] The bottom wall 523 of the light guide 52 is usually made into dot features by laser, silk screen printing, molding, etc., which is used to adjust the light path so that the light can be emitted more evenly from the top wall 524 of the light guide 52.

[0081] In some examples, such as Figure 11 As shown, the edge of the light-transmitting cover 2 has a limiting protrusion 22. The limiting protrusion 22 is annular and surrounds the light guide 52, and is in contact with the outer wall 522 of the light guide 52. As a result, the top wall 524 of the light guide 52 is located inside the light-transmitting cover 2, thereby preventing infrared light from the top wall 524 from leaking outside the light-transmitting cover 2.

[0082] A limiting step is formed on the inner wall of the limiting protrusion 22 , and the light guide 52 abuts against the limiting step, thereby achieving axial limiting of the light guide 52 .

[0083] In some examples, such as Figure 12 As shown, the inner wall 521 has a plurality of grooves 5211. Figure 11 As shown, the fill light assembly 4 includes a plurality of fill light lamps 42, each of which is located in a groove 5211. In this way, there is no gap between the fill light lamp 42 and the light guide 52, thereby ensuring that the light emitted by the fill light lamp 42 can effectively enter the interior of the light guide 52, thereby avoiding light leakage and reducing light energy loss.

[0084] In other examples, the inner wall 521 may also have an annular groove, and the multiple fill lights 42 are located in the same annular groove.

[0085] In some examples, such as Figure 11As shown, the light guide 52 includes a light guide body 525 and a reflective sticker 526. The reflective sticker 526 is attached to the outer wall of the light guide body 525 and is used to reflect light emitted from the outer wall of the light guide body 525. The side of the reflective sticker 526 near the light guide body 525 is made of a highly infrared reflective material and is used to reflect light from the light guide body 525, preventing infrared light from escaping from the light guide body 525 and increasing the light passing through the top wall 524 of the light guide body 52 to the camera light shield 2.

[0086] In other examples, the reflective sticker 526 may also be attached to the light guide body 525 by spraying.

[0087] In some examples, the top wall 524 of the light guide 52 may be planar or curved, which is not specifically limited in the embodiments of the present disclosure.

[0088] In some examples, such as Figure 10 and Figure 11 As shown, the reflector assembly 5 also includes a mounting frame 53, which is used to secure the light guide 52 and the fill light assembly 4. The mounting frame 53 includes a first mounting plate 531 and a second mounting plate 532. The first mounting plate 531 is annular and fixed to the outside of the lens module 3. The fill light assembly 4 surrounds the first mounting plate 531. The second mounting plate 532 is annular and arranged in a curved manner relative to the first mounting plate 531. The second mounting plate 532 abuts against the bottom wall 523 of the light guide 52. The second mounting plate 532 and the light-transmitting cover 2 axially position the light guide 52, preventing displacement of the light guide 52 during use and affecting the light guiding effect.

[0089] like Figure 11 As shown, a closed cavity is formed between the second mounting plate 532, the groove 5211 and the light board 41, thereby preventing the infrared light emitted by the fill light 42 from leaking to the outside of the mounting frame 53 and the light guide 52, ensuring that the infrared light emitted by the fill light 42 can effectively enter the interior of the light guide 52, and reducing the energy loss of the light.

[0090] In some examples, the first mounting plate 531 and the second mounting plate 532 are made of aluminum. Aluminum has a high infrared reflectivity and excellent heat dissipation. When the fill light assembly 4 is in operation, the fill light 42 generates heat and transfers it to the light board 41. The light board 41 fits snugly against the first mounting plate 531, allowing the first plate 511 to effectively dissipate heat from the light board 41. Furthermore, aluminum is lightweight, so the first and second mounting plates 531, 532, do not add excessive weight to the camera.

[0091] In some examples, a heat conducting component is provided between the first mounting plate 531 and the fill light assembly 4. When the fill light assembly 4 is in operation, the fill light 42 generates heat, and the heat conducting component can transfer the heat of the fill light assembly 4 to the first mounting plate 531, thereby reducing the temperature of the fill light assembly 4.

[0092] The above descriptions are merely optional embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the principles of the present disclosure shall be included in the scope of protection of the present disclosure.
