Many particular details are described in the following description to facilitate sufficient comprehension of the present disclosure, but the present disclosure may also be implemented in manners different from those described herein. Apparently, the embodiments in the description are merely some of the embodiments of the present disclosure, rather than all of the embodiments.
In related art, an internal lens and a reflecting mirror are assembled together by snap fitting. After mass production, because of the thickness of the wall element, after the wall element is injection-molded, its deformation is different from the trend in deformation of the subassembly of the internal lens and the reflecting mirror, which causes that the gap between the wall element and the internal lens are inconstant. Since the gap between the wall element and the internal lens forms dark lines at the front surface of the wall element, if the gap is inconstant, it will cause the dark lines seen from the front surface of the lamp to have unequal widths, thereby affecting the appearance.
In view of the above, the embodiments of the present disclosure provide a lamp, in which, by the adjustment of the relation and the sequence in the assembling of the wall element, the internal lens and the reflecting mirror, the gap between the wall element and the internal lens is constant, to ensure the evenness of the appearance of the dark lines seen from the front surface of the lamp.

The internal lens 3 includes a main body 35, a first protruding part 33 and a second protruding part 34, and both of the first protruding part 33 and the second protruding part 34 abut the wall element 4, whereby the main body 35 of the internal lens 3 and the wall element 4 form a gap therebetween. By using the first protruding part 33 and the second protruding part 34, the main body 35 of the internal lens 3 and the wall element 4 may form a constant gap therebetween, which ensures the uniformity and the optical effect, improves the optical uniformity of the transparent wall element 4, and prevents unevenness of the dark lines.
The internal lens 3 may be manufactured by using any material that satisfies the requirement on the light transmittance.

In some embodiments, the internal lens 3 is a thin-wall injection-molded piece used for optical uniformization, the internal lens 3 may be manufactured by using various materials, for example, a diffusible material, and the internal lens 3 is joined to the front wall element 4 by secondary injection molding to form a combined optical solution to ensure the optical uniformity and the optical effect. In some embodiments, the internal lens 3 may be a PC photodiffusion plastic, i.e., a light-transmitting but non-transparent photodiffusion-material particle that is formed by polymerization in a special process with a transparent PC (polycarbonate) plastic as the matrix, and a photo-diffuser and other additives of a certain proportion. The wall element 4 may be manufactured by using any material that satisfies the requirement on the light transmittance. In some embodiments, the wall element 4 is manufactured by using a material having a light transmittance greater than or equal to 90%. In some embodiments, the wall element 4 is an injection-molded piece used for optical uniformization. The reflecting mirror 2 may be of a metal material, and may also be of a plastic material. In some embodiments, the reflecting mirror 2 is a plastic injection-molded piece with or without aluminum plating for light-ray.
In some embodiments, the wall element 4 includes a light entering part 44 and a light exiting part 43. In the height direction of the wall element 4, the distance L1 (not shown in the figure) between the first protruding part 33 and the second protruding part 34 satisfies L2<L1<L3, where L2 is the thickness of the light exiting part 43, and L3 is the thickness of the light entering part 44. That may ensure the constant gap between the main body 35 of the internal lens 3 and the wall element 4, so that the dark lines seen from the front surface of the lamp have even widths, to ensure the effect of uniform lightening. The embodiment of the present disclosure, while ensuring the transparency of the wall element and the effect of suspension, ensures the uniformity and the optical effect, improves the optical uniformity of the transparent wall element 4, and prevents unevenness of the dark lines.

When the second snap-fitting component and the second mounting part are connected by snap fitting, one of the second snap-fitting component and the second mounting part may be provided with a snap-fitting protrusion, the other of the second snap-fitting component and the second mounting part may be provided with a snap-fitting slot or a snap-fitting hole, and the position of the snap-fitting slot or the snap-fitting hole corresponds to the snap-fitting protrusion, so that the snap-fitting protrusion is snap-fitted to the snap-fitting slot or the snap-fitting holc.
The first snap-fitting component and the first mounting part, and the second snap-fitting component and the second mounting part, may be connected in any suitable manner, as long as the internal lens 3 and the wall element 4 may be connected together, whereby the internal lens 3 may deform following the contour of the wall element 4. As the internal lens 3 deforms following the wall element 4, the constant gap between the main body 35 of the internal lens 3 and the wall element 4 may be ensured, which ensures evenness of the dark lines, to ensure the effect of uniform lightening. The embodiment of the present disclosure, while ensuring the transparency of the wall element and the effect of suspension, ensures the uniformity and the optical effect, improves the optical uniformity of the transparent wall element 4, and prevents unevenness of the dark lines.

The installation may include inserting the protrusion 41 into the snap-fitting slot 311, subsequently rotating the internal lens 3 with the position of the protrusion 41 as the shaft, to cause the top of the internal lens 3 to approach the wall element 4, and finally connecting the second snap-fitting component to the second mounting part, whereby the internal lens 3 and the wall element 4 may be fixed together. Which cannot only prevent shaking of the internal lens 3, but also simplifies the assembling of the internal lens 3 and the wall element 4, which increases the efficiency of the assembling of the internal lens 3 and the wall element 4, and thus increases the efficiency of the assembling of the lamp. In the embodiments of the present disclosure, as the internal lens 3 and the wall element 4 are connected together, the internal lens 3 may deform following the contour of the wall element 4, to ensure the constant gap between the main body 35 of the internal lens 3 and the wall element 4, which ensures evenness of the dark lines, to ensure the effect of uniform lightening. Furthermore, the embodiment of the present disclosure, while ensuring the transparency of the wall element and the effect of suspension, ensures the uniformity and the optical effect, improves the optical uniformity of the transparent wall element 4, and prevents unevenness of the dark lines.
In some embodiments, the protrusion 41 includes a first abutting surface 411 and a first directing bevel 412, the first directing bevel 412 is disposed close to the internal lens 3, and the first directing bevel 412 inclines from the bottom surface of the wall element 4 toward the first abutting surface 411. When the protrusion 41 and the snap-fitting slot 311 are connected by insertion, the first directing bevel 412 may facilitate the protrusion 41 to be clipped to the snap-fitting slot 311, and such a structure is simple and easy to implement. The installation may include inserting the protrusion 41 into the snap-fitting slot 311, subsequently rotating the internal lens 3 with the position of the protrusion 41 as the shaft, to cause the internal lens 3 to bypass the first directing bevel 412, to cause the top of the internal lens 3 to approach the wall element 4, and finally connecting the second snap-fitting component to the second mounting part. At this point, the first abutting surface 411 abuts the side wall of the snap-fitting slot 311, so that the internal lens 3 and the wall element 4 are fixed together. Which cannot only prevent shaking of the internal lens 3, but also simplifies the assembling of the internal lens 3 and the wall element 4, which increases the efficiency of the assembling of the internal lens 3 and the wall element 4, and thus increases the efficiency of the assembling of the lamp. As the internal lens 3 and the wall element 4 are connected together, the internal lens 3 may deform following the contour of the wall element 4, to ensure the constant gap between the main body 35 of the internal lens 3 and the wall element 4, which ensures evenness of the dark lines, to ensure the effect of uniform lightening. The embodiment of the present disclosure, while ensuring the transparency of the wall element and the effect of suspension, ensures the uniformity and the optical effect, improves the optical uniformity of the transparent wall element 4, and prevents unevenness of the dark lines.
In some embodiments, the second snap-fitting component includes a snap-fitting block 32 extending from the internal lens 3 toward the wall element 4, the second mounting part includes a snap-fitting hole 42, and the snap-fitting block 32 is snap-fitted to the snap-fitting hole 42. The installation may include inserting the protrusion 41 into the snap-fitting slot 311, subsequently rotating the internal lens 3 with the position of the protrusion 41 as the shaft, to cause the internal lens 3 to bypass the first directing bevel 412, to cause the top of the internal lens 3 to approach the wall element 4, and finally snap-fitting the snap-fitting block 32 to the snap-fitting hole 42. At this point, the internal lens 3 and the wall element 4 are fixed together. Which cannot only prevent shaking of the internal lens 3, but also simplifies the assembling of the internal lens 3 and the wall element 4, which increases the efficiency of the assembling of the internal lens 3 and the wall element 4, and thus increases the efficiency of the assembling of the lamp. As the internal lens 3 and the wall element 4 are connected together, the internal lens 3 may deform following the contour of the wall element 4, to ensure the constant gap between the main body 35 of the internal lens 3 and the wall element 4, which ensures evenness of the dark lines, to ensure the effect of uniform lightening. The embodiment of the present disclosure, while ensuring the transparency of the wall element and the effect of suspension, ensures the uniformity and the optical effect, improves the optical uniformity of the transparent wall element 4, and prevents unevenness of the dark lines.
In some embodiments, the snap-fitting block 32 includes a side surface 321, the side surface 321 is provided with a boss 322, and the snap-fitting block 32 is inserted into the snap-fitting hole 42 to cause the boss 322 to be snap-fitted to the snap-fitting hole 42. The installation may include inserting the protrusion 41 into the snap-fitting slot 311, subsequently rotating the internal lens 3 with the position of the protrusion 41 as the shaft, to cause the top of the internal lens 3 to approach the wall element 4, and finally the boss 322 passes through the snap-fitting hole 42 and is snap-fitted to the snap-fitting hole 42 after inserting the snap-fitting block 32 into the snap-fitting hole 42. At this point, the internal lens 3 and the wall element 4 are connected together. Which cannot only prevent shaking of the internal lens 3, but also simplifies the assembling of the internal lens 3 and the wall element 4, which increases the efficiency of the assembling of the internal lens 3 and the wall element 4, and thus increases the efficiency of the assembling of the lamp.
In some embodiments, the boss 322 includes a second abutting surface 322a and a second directing bevel 322b that intersect, the second abutting surface 322a extends from the side surface 321 toward the second directing bevel 322b, and the second directing bevel 322b extends from the side surface 321 toward the second abutting surface 322a. The snap-fitting block 32 is inserted into the snap-fitting hole 42, so that the second abutting surface 322a abuts the wall element 4. The second directing bevel 322b may facilitate the boss 322 to pass through the snap-fitting hole 42, so that the second abutting surface 322a of the boss 322 abuts the wall element 4. Such a structure is simple and easy to implement, which increases the efficiency of the assembling of the internal lens 3 and the wall element 4, and thus increases the efficiency of the assembling of the lamp. The boss 322 passes through the snap-fitting hole 42 and is snap-fitted to the snap-fitting hole 42, to connect the internal lens 3 and the wall element 4 together. Which cannot only prevent shaking of the internal lens 3, but also simplifies the assembling of the internal lens 3 and the wall element 4. The particular installation process may include inserting the protrusion 41 into the snap-fitting slot 311, subsequently rotating the internal lens 3 with the position of the protrusion 41 as the shaft, to cause the internal lens 3 to bypass the first directing bevel 412, to cause the top of the internal lens 3 to approach the wall element 4, and finally inserting the snap-fitting block 32 into the snap-fitting hole 42 along the second directing bevel 322b. After the boss 322 of the snap-fitting block 32 passes through the snap-fitting hole 42, by the rebounding force of the internal lens 3, the second abutting surface 322a abuts the wall element 4. Such a structure is simple and easy to implement, which increases the efficiency of the assembling of the internal lens 3 and the wall element 4, and thus increases the efficiency of the assembling of the lamp. As the internal lens 3 and the wall element 4 are connected together, the internal lens 3 may deform following the contour of the wall element 4, to ensure the constant gap between the main body 35 of the internal lens 3 and the wall element 4, which ensures evenness of the dark lines, to ensure the effect of uniform lightening. Furthermore, the embodiment of the present disclosure, while ensuring the transparency of the wall element and the effect of suspension, ensures the uniformity and the optical effect, improves the optical uniformity of the transparent wall element 4, and prevents unevenness of the dark lines.
In some embodiments, the included angle between the second abutting surface 322a and the side surface 321 is less than the included angle between the second directing bevel 322b and the side surface 321. When the snap-fitting block 32 is inserted into the snap-fitting hole 42 along the second directing bevel 322b, the second directing bevel 322b facilitates the snap-fitting block 32 to be inserted into the snap-fitting hole 42, which may increase the efficiency of the assembling. After the snap-fitting block 32 is inserted into the snap-fitting hole 42 along the second directing bevel 322b and the boss 322 passes through the snap-fitting hole 42, the second abutting surface 322a abuts the wall element 4, and because the included angle between the second abutting surface 322a and the side surface 321 is larger, the stability of the connection may be increased, and the possibility with which the internal lens 3 shakes may be reduced. In some embodiments, the included angle between the second abutting surface 322a and the side surface 321 is 90°, which may increase the stability of the connection, and reduce the possibility with which the internal lens 3 shakes.
In some embodiments, the first mounting part and the second mounting part are staggered in the height direction of the wall element 4, which may increase the stability of the connection, and reduce the possibility with which the internal lens 3 shakes.
