Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
Because the mobile lighting equipment capable of automatically dimming is widely applied to our daily life, in order to realize the automatic dimming of the mobile lighting equipment, a part of lens paraboloids are cut off, luminous flux is sacrificed, light sensation is arranged at a certain position for control, and the light reflected back into the cavity by the outside is used for detection, so that the light sensation downshift function is realized. However, the conventional mobile lighting devices have a problem that the hardness of the surface of the lens is insufficient because the lens is made of plastic, and the surface of the lens is easy to be ground when a user uses the flashlight outdoors. When the surface of the lens right in front of the corresponding installation light sense is ground, the inner surface of the ground part of the lens is in a fog form, and diffuse reflection can be generated when light rays are emitted to the fog form. When the light source is lighted, even if no obstacle exists in front of the flashlight, diffuse reflection can enable light to return to the inside of the lens, the light can form internal reflection on the inner surface of the grinding flower, and the light-sensitive receiver can receive light energy, so that the mobile lighting equipment is downshifted. The present invention is therefore directed to a head assembly, with reference to fig. 1-4, comprising: a main body 100, a first optical member 200, and a light-sensitive receiver 300; the main body 100 has an accommodating space 110 formed therein; the first optical member 200 is disposed in the accommodating space 110, and the first optical member 200 includes: the light incident hole 210 is arranged at the first end of the first optical component 200 and used for accommodating the luminescent light source 800, and the light emergent surface 220 is arranged at the second end of the first optical component 200, a concave area 221 is arranged on the light emergent surface 220, and the first end and the second end of the first optical component 200 are opposite; the light-sensing receiver 300 is installed in the accommodating space 110 and positioned at a first end of the first optical member 200 for receiving the reflected light reflected from the outside into the body 100, and the light-sensing receiver 300 faces the recess region 221. In this embodiment, the first optical component 200 is a TIR total reflection lens.
Since the lens is polished when in use, the plane of the concave region 221 is lower than the plane of the light-emitting surface 220, and the concave region is not polished. Referring to fig. 5, the concave area 221 is disposed on the light-emitting surface 220, and the concave area 221 faces the light-sensitive receiver 300, so that it is possible to prevent the area of the light-emitting surface 220 of the lens facing the light-sensitive receiver 300 from being ground, and even if the light-emitting surface 220 of the lens is ground, light can still enter the concave area 221 or be emitted from the concave area 221, so that the light-sensitive sensor can work normally, and the light-sensitive receiver 300 is prevented from erroneously recognizing that there is an obstacle in front due to light energy diffusely reflected by the area of the light-emitting surface 220 facing the sensor, which results in automatic downshifting of the mobile lighting device when in use, thereby improving the use experience of the user when using the mobile lighting device.
In one embodiment, since the light receiver 300 faces the concave region 221 and the path of the light beam propagates along a straight line, the end surface of the concave region 221 near the light receiver 300 is required to be a plane in the present embodiment; only when the end surface of the concave area 221 near the side of the light-sensitive receiver 300 is a plane, the light entering the lens can act on the sensor receiver, so as to ensure that the mobile lighting device can accurately adjust the light according to the light received by the light-sensitive receiver 300. In this embodiment, the end surface of the concave area 221 near the light-sensitive receiver 300 is a plane, which can be only set as a plane, and if it is a cambered surface, the light is deflected, so that it is difficult to ensure that the light acts on the light-sensitive receiver 300.
In one embodiment, the concave region 221 is offset from the light incident hole 210; through with sunk region 221 and income unthreaded hole 210 dislocation set, can avoid reflected light to enter into unthreaded hole 210 in, and cause the interference to the light that enters into in the first optical part 200 from sunk region 221, guarantee that light sense receiver 300 can accurately receive the light that is penetrated into in the first optical part 200 from sunk region 221, promote the accuracy when moving the automatic gear shifting of lighting apparatus.
In one embodiment, referring to fig. 6, the first optical component 200 has a first reflective surface 230 on an outer sidewall thereof, and the head assembly further comprises: and a second optical member 400, wherein the second optical member 400 is disposed on the first optical member 200 such that an annular cut portion is formed between the second optical member 400 and the first optical member 200, and the second optical member 400 has a second reflection surface 410 on an inner side wall thereof, and the first reflection surface 230 is opposite to the second reflection surface 410. In this embodiment, the second optical member 400 is a lens. Since the mold insert of the paraboloid of the TIR total reflection lens adopted by the first optical component 200 is not a mirror surface after machining, the emitting surface has a knife grain, namely has roughness, and the effect close to the mirror surface can be achieved through a post-machining polishing process, so that in practice, the post-machining polishing process is performed, in order to keep the original curve precision of the paraboloid, the knife grain cannot be polished to be a mirror surface, and some tiny rough surfaces exist, so that light can leak out from the surfaces, therefore, in the embodiment, the second optical component 400 is arranged, the second optical component 400 is covered on the first optical component 200, so that an annular cutting part is formed between the second optical component 400 and the first optical component 200, the second reflecting surface 410 is arranged on the inner side wall of the second optical component 400, and the first reflecting surface 230 is opposite to the second reflecting surface 410, so that the first optical component 200 and the second optical component 400 can form a double-layer total reflection lens; when the mobile lighting device is in operation, part of the light generated by the light-emitting source 80 will act on the first reflecting surface 230, and when a small amount of light leaks from the first reflecting surface 230, the leaked light will be totally reflected again by the second reflecting surface 410, and then is reflected back into the first optical component 200 and projected to the front from the light-emitting surface 220, so that the originally leaked light can be reused, thereby improving the luminous flux of the mobile lighting device when in use and reducing the waste of light energy.
In one embodiment, the second end of the second optical member 400 is fixed to the second end of the first optical member 200. In this embodiment, the first optical member 200 is integrally formed with the second optical member 400.

The substrate 500 is located between the light-sensitive receiver 300 and the first optical member 200, and a through hole 510 is further formed in the substrate 500, where the through hole 510 faces the light-sensitive receiver 300. Since the substrate 500 is located between the light-sensing receiver 300 and the first optical member 200, the substrate 500 interferes with the light that is applied to the light-sensing receiver 300, and thus in order to ensure that the light that is incident into the first optical member 200 from the concave region 221 can be applied to the light-sensing receiver 300 normally, the through holes 510 are required to ensure that the light can be applied to the light-sensing receiver 300 through the through holes 510.
In one embodiment, two opposite insertion holes 520 are provided, and two insertion posts 420 extend from the first end of the second optical member 400 toward the substrate 500, and the insertion posts 420 are inserted into the insertion holes 520.
