Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
The grid light-emitting lamp shown in fig. 1 to 7 is mainly applied to light emission of a grid at a front end bumper of an automobile body.
In the figure, 1 is an external mask, 2 is a luminous thick-wall internal lens, 3 is a protective cover, 4 is a lamp body, 5 is a luminous light guide, 6 is a circuit board radiator assembly, 7 is a fixed light guide support, and 8 is an LED light source.
The principle of luminescence is as follows: the LED light source 8 is fixed on the circuit board radiator assembly 6, the parts are fixed on the lamp body 4 through a screw structure, the light guide part is a grating corresponding to 2 light guides, the parts are independent respectively (two parts which are symmetrical left and right in the figure), the parts are fixed together through the fixed light guide support 7, the fixed light guide support 7 and the circuit board radiator assembly 6 are fixed through a certain positioning structure, the parts can be screws or positioning pins or buckles, and at the moment, the assembly of the light source part is fixed.
In order to achieve a uniform lighting effect, the light source must be placed in the middle of the grid, and the light guide uses lighting optics, as can be seen in fig. 6 and 7, and with reference to the other figures, the light source delivers light to the diverging ends of the light guide (the middle upper and lower segmented region of fig. 7) by fixing a portion of the short light guide 50 area on the light guide holder 7, the light guide bifurcation area in fig. 7 has a triangular structure 53 (shown as an isosceles right triangle, with the right angle facing short light guide 50), which is a triangular prism-shaped hollow cavity, the light of the light-emitting light guide 5, here in particular the short light guide 50, is reflected in this triangular region by total internal reflection from above and below by means of its corresponding facets, thereby splitting a beam emitted from the light guide into two beams, which are transmitted through the upper and lower light guide parts 51 and 52 to form a ring-shaped light emitting structure. In the two grid-type light-emitting lamp structures which are symmetrical left and right in the figure, the left light guide pipe and the right light guide pipe are respectively separated towards two sides (that means two short light guides respectively extend towards two sides), and a triangle which appears at the branch of the root of the light guide pipe is an important optical structure for guiding light from the main light guide pipe area to the branch area of the light guide pipe.
However, on the other hand, since the lighting effect of the light guide teeth occurs after the light guide emits light, which is not the original design, and the visible effect of the light guide teeth is not desired in the optical effect required in the present technical solution, a thick-walled inner lens member, i.e., a structure represented by reference numeral 2 in the drawing, is added in front of the light guide, and as shown in fig. 2, the light-emitting thick-walled inner lens 2 has an optical incident surface 21, and the light-emitting light guide 5 (the light guide 5 in fig. 2 substantially indicates a branched light guide 51) is located in front of the optical incident surface 21 and hidden behind the outer cover 1. Light from the light guide 5 enters the thick-wall internal light distribution mirror 2 through the optical incidence surface 21, is reflected by the total reflection surface 22 to the other total reflection surface 23, is reflected by the total reflection surface 23 to the optical exit surface 24 for exiting, and reaches the outside of the vehicle body through the grid holes 9 of the grid; the entire light path is shown schematically by arrow C in fig. 2.
That is, the light passes through the thick-walled inner lens 2 by using the principle of two total reflections for light transmission, the left side in fig. 2 is provided with two total reflection surfaces 22 and 23 forming an included angle of 45 degrees with the horizontal plane, when the light guide reflects the light to the first total reflection surface 22, the light is reflected from right to left, after passing through the first total reflection surface 22, the light is reflected to the second total reflection surface 23, the light at this time is from top to bottom, and then the light is reflected to the thick-walled inner light distribution area with visible appearance through the second total reflection surface 23, that is, the light is transmitted from left to right and finally captured by the outside air.
The outer face shield and the thick-wall inner lens are fixed by laser welding, and the protective cover is fixed with the lamp body through magnetic connection. Reference numerals 11 and 12 in the figures illustrate two different welding zones. Reference numerals 13 and 14 in the figure illustrate two different glue areas.
The direction of travel of the light rays indicated by the arrow d in fig. 5 is similar to that in fig. 2.
Compared with the old implementation mode, the novel implementation mode enables the modeling to be more flexible in overall appearance layout and rich in artistic sense, when the product is not lightened, the product keeps the original effect and function, and when the product is lightened, the familiarity of the grid light-emitting lamp can be highlighted, so that the vehicle identification degree is further improved, and the personalized requirements of customers are met.
Compared with the prior art, the optical and structural design scheme fully solves the design problem of light guide uniformity, fully considers the cost problem of products and fully considers the problem of maintaining the original structure.
