In other embodiments, the privacy lens 12 may be applied to other devices that need privacy protection according to requirements, so as to improve the technical privacy effect on the other devices.
In one embodiment, the peep-proof lens 12 may be disposed on the lamp base body 11 by clamping, adhering, screwing or clamping.
For example: the size of the peep-proof lens 12 can be designed to be similar to that of the light outlet 1121, so that the peep-proof lens 12 is directly clamped and fixed on the light outlet 1121; alternatively, threads may be provided on the edge of the privacy lens 12, and threads may be provided on the base body 11 (at the light outlet 1121), so that the privacy lens 12 is screwed on the base body 11; alternatively, an adhesive may be provided on the base body 11 or the privacy lens 12, so that the two can be adhered; alternatively, the base body 11 may be a split structure formed of two parts, so that the privacy lens 12 is sandwiched between the two parts.
The above description of the arrangement of the privacy lens 12 and the lamp head body 11 is merely exemplary and should not be construed as limiting the invention, as those skilled in the art may select a particular arrangement in a particular embodiment.
When the peep-proof lens 12 is applied to other devices, the setting mode of the peep-proof lens 12 and the lamp holder main body 11 may be referred to for the setting mode of the housing or other structures of other devices, and the description thereof will be omitted.
In one embodiment, the privacy lens 12 may be made of transparent plastic or glass to avoid interfering with the exit of light.
In a preferred embodiment, the privacy lens 12 is made of transparent plastic.
In one embodiment, the lamp base body 11 may include a housing 111 and an upper cover 112 disposed on top of the housing 111, the light emitting element 14 and the reflector 13 are disposed in the housing 111, a limiting periphery is formed by extending the top of the upper cover 112 inward, the light outlet 1121 is an opening surrounded by the limiting periphery, the peep-proof lens 12 is sandwiched between the housing 111 and the limiting periphery, and the peep-proof structure 121 is exposed from the light outlet 1121.
In the present embodiment, the housing 111 is an external structure of the base body 11, and is used for accommodating and disposing the reflector 13, the upper cover 112, the light emitting element 14, the reflector 13, and the like.
The housing 111 and the upper cover 112 may be made of plastic, so as to be designed into a desired shape, and have better strength and hardness, so that the protection of the internal structure and the service life of the housing can be improved.
In one embodiment, the upper cover 112 is detachably disposed on the housing 111, for example, the two can be detachably disposed by a threaded connection, a snap connection, a screw connection, etc., so that the reflector 13, the light emitting element 14, etc. can be conveniently mounted in the housing 111 or detached from the housing 111 after the two are detached and separated, and the operation is easier.
If the anti-peeping lamp cap 10 is too easy to be detached by a user, the screws are selected to fix the upper cover 112 and the housing 111 in a better protection manner.
In one embodiment, the light entering the interior of the lamp cap body 11 from the outside through the peep-proof structure 121 via the light outlet 1121 and having an angle greater than or less than the set angle range with respect to the peep-proof structure 121 is refracted and deflected or deformed by the peep-proof structure 121.
It will be appreciated that since the privacy structure 121 is an optical structure, the light (line of sight) may have no or only a small refractive or deformable effect on the light at some angles relative to the privacy structure 121, such as, for example, where the light is at a 90 ° angle relative to the privacy structure 121.
Therefore, the light rays which enter the lamp holder main body 11 from the outside through the peep-proof structure 121 and are more or less than the set angle range formed by the peep-proof structure 121 are designed to be refracted and deflected or deformed by the peep-proof structure 121, and the internal structure of the peep-proof lamp holder 10 can be still protected from being seen in a larger range.
In one embodiment, the set angle range may be 90++5°, that is, 85 ° to 95 °, that is, the internal structure of the peep-proof lamp cap 10 cannot be seen when the line of sight of the observer is smaller than 85 ° and larger than 95 ° relative to the peep-proof lamp cap 10, so that the line of sight of the observer can only see the internal structure of the peep-proof lamp cap 10 in a small range, and no excessive influence exists, and the peep-proof structure 121 can still effectively protect the structural features in the peep-proof lamp cap 10.
In one embodiment, the peep-proof structure 121 covers the light-emitting path of the light emitted from the light-emitting port 1121, and the orthographic projection of the peep-proof structure 121 toward the lamp base body 11 falls on the light-emitting element 14.
Thus, the peep-proof structure 121 can comprehensively change the sight line of an observer looking into the internal structure of the peep-proof lamp cap 10 from outside to inside, realize comprehensive protection confidentiality and improve the protection effect.
Referring to fig. 1 to 3, in one embodiment, the privacy lens 12 includes a lens body 122 and a mounting periphery 123 surrounding an edge of the lens body 122, the privacy structure 121 is disposed on an inner surface of the lens body 122, and when the privacy lens is applied to the privacy cap 10, an outer surface of the lens body 122 is exposed from the light outlet 1121, and a shape of the mounting periphery 123 is adapted to a shape of the cap body 11 at the light outlet 1121.
In this embodiment, the outer surface of the lens body 122 is a plane and is exposed from the light outlet 1121, so that the top surface of the peep-proof lamp cap 10 presents a regular and attractive plane, the mounting periphery 123 can be understood as a ledge or flange extending outwards from the edge of the lens body 122, the shape of the ledge or flange is matched with that of the lamp cap, and the outer surface of the mounting periphery 123 is also a plane, so that the assembly of the peep-proof lens 12 and the lamp cap body 11 is more compact, impurities, water vapor and the like are reduced to enter the lamp cap body 11, the overall tightness is improved, the stability of the peep-proof lens 12 in the lamp cap body 11 is improved, and the damage of the lens body 122 during assembly and disassembly can be reduced by the mounting periphery 123.
In the case where the peep-proof lens 12 is applied to other devices, the specific structure, the positional relationship of the relative fixed structure, and the like of the peep-proof lens 12 in the peep-proof cap 10 may be referred to, and the detailed description thereof will be omitted herein.
In one embodiment, privacy structure 121, lens body 122, and mounting perimeter 123 are integrally formed.
That is, the mounting periphery 123 can be integrally formed with the lens body 122 and the peep-proof structure 121, so that the production process can be simplified to reduce the production cost, and the structural integrity is better.
Of course, the peep-proof structure 121, the mounting periphery 123 and the lens main body 122 may be separate structures, which is more convenient to replace when any one of them is damaged.
Referring to fig. 4, in one embodiment, the privacy structure 121 is a grating structure.
Specifically, after the light emitted by the light emitting element 14 is adjusted by the reflector 13, the light emitting effect is similar to that of parallel light, and by arranging regular gratings on the inner surface of the lens main body 122, most of the parallel light can smoothly pass through the gratings, and the effect of controlling the light direction is achieved.
The lateral light with larger angle can cause reflection and deflection through the convex part of the grating, so that the inside of the peep-proof lamp cap 10 can be basically and only seen from the outside, and a little micro-strip can generate more virtual images when seen from the angle side, so that the internal structure cannot be seen clearly, and the peep-proof protection technology detail effect is achieved.
In one embodiment, the grating structure may be a plurality of triangular/tetragonal prism gratings arranged in parallel, so that the cross section of the lens body 122 is saw-tooth, and light rays deviate from the arrangement direction of the triangular/tetragonal prism array due to refraction of the prisms when seen from outside to inside, thereby realizing effective protection of the internal structure of the peep-proof lamp cap 10.
Referring to fig. 5 to 8, in one embodiment, the privacy structure 121 is a concave-convex grating structure.
On the basis that the peep-proof structure 121 is a grating structure, the peep-proof structure can be further arranged into a concave-convex grating structure, namely, the grating structure comprises a plurality of concave lens units 1211 and a plurality of convex lens units 1212 which are arranged at intervals, and the plurality of concave lens units 1211 and the plurality of convex lens units 1212 are combined into a concave-convex lens array, so that when an observer looks into the peep-proof lamp holder 10, a part of sight line can be enlarged, and a part of sight line can be reduced, so that the observer has poor vision or vision change, and a certain peep-proof effect is achieved.
Referring to fig. 5, in one embodiment, the peep-proof structure 121 is a parallel lenticular structure, and the parallel lenticular structure includes a plurality of lenticular lens units 1211 and a plurality of lenticular lens units 1212, and the plurality of lenticular lens units 1211 and the plurality of lenticular lens units 1212 are arranged in parallel and alternately.
