M297876 VIII. New description: [New technical field] This creation is a light guiding structure that can be installed on the illuminator of a car and can make the illuminating body emit light with uniform brightness. [Prior Art] ^The illuminant currently installed in a car or various vehicles has various illuminators provided in order to display a specific component. For example, the Taiwan patent notice is M279538 "The position of the headlight ring of the lamp" The new patent case is designed to have a ring-shaped aperture, and a light-emitting element is provided on the light-guiding ring. When the light is irradiated in the opposite direction and toward the axial direction of 7 and toward V, 4' can be in its light guide ring. The prior art aperture ring has a specific light guiding structure, as shown in the sixth and seventh figures, the 'optical aperture (3〇)" is formed into a planar shape, and: the upper surface is formed as a matte surface (3 2), The other side is the front side 1) for viewing, the aperture (3〇) is provided with a chamber (33), and (3 3) is provided with a light-emitting element (3 4 )

, Λ; therefore, when the two light bodies of the light-emitting element (S 4) are illuminated, the light in the ° direction is emitted toward the aperture day, so that the aperture (3 〇) is present on the front side ring..., image; 囟c 31) Bright light is now due to the light guiding structure of the prior art, although the front side torus (3 1 ) can be made to generate light A ^ 32) ^ nine children, but by the light-emitting element (3 is set at a specific position of the aperture (30) # ,Λ Make the brightness at the position close to the illuminating element Γ 4) higher, and vice versa, /, (3 &< 'in the illuminating element (the height of the position is not enough, therefore, I The M297876 presented by the first ring of the limb (30) makes the aura of the aura extremely uneven (as shown in the eighth figure, the appearance is less beautiful. [New content] The light guide has the above-mentioned problems in view of the prior art. And the disadvantages are redesigned for it so that the light guide structure can be designed: the positions of the overall illuminant can be more uniform and brighter, and the rut is better and the display effect is better. Practical creation. In order to achieve the aforementioned creative purposes, the agency The technical means is to provide a light guiding structure of the illuminant, in which a flat surface is formed on the body-side of the strip or the ring, and the other side is a display surface, and several planes are formed at the plane. In the concave light groove, the spacing between the optical grooves is smaller as the distance between the optical grooves formed in the opposite direction, that is, the dense groove is smaller at the interval of the light groove, and the uneven surface is larger at the interval. The light guide of the illuminator is a mounting surface, and the mounting surface is formed with a mounted chamber. The slanting section of the body is provided with a recess for further providing illumination of the illuminant of the illuminating element. a structure in which the cross-sectional shape of the body is curved in a plane on the other side with respect to the plane. The light guiding structure of the illuminating body, wherein the illuminating element provided in the chamber has two directions toward the loose section Light-emitting light bulb. The light-guiding structure of the illuminant, wherein the mounting surface is provided with two protruding fixed 枉' illuminating elements, and a circuit board capable of arranging a light bulb, which is sleeved and fixed to each other Fixed hole. By front The design of the structure, the light guiding structure designed by the present invention, is formed on the surface of the M297876 with a facet section close to the light emitting element and a facet surface away from the position of the light emitting element, so that when the projected light and the light groove are mutually The effect Ling 17 can form a brightness on the surface of the exhibition, and the distance between the light of the facet surface toward the close surface & is gradually reduced, so that the brightness presented at the display surface will be relatively close and uniform. 】 See the first and second figures of Fen, the embodiment of the light-guide structure designed by the author is set on the illuminant. The body of the illuminator (1) 〇 is constructed in % in the household and the example. In one embodiment, a flat surface (1) 2) is formed on one side of the annular center (10), and the other side is a curved display surface (1 1 ), which is mounted on a vehicle as an example. The exhibition face (1 1 ) is oriented toward the outside of the vehicle; and on the ring plane (12) ::::: (14) of the body (10), there is a concave surface at the mounting surface ("): Also on the mounting surface (14) and in the chamber (1 An F surface: two ends are formed with protrusions The fixing post (142), and further, a light-emitting element (2〇) is provided at 14). 70 (20) of the bulb (21) on the circuit board (2 2 ) on the set circuit board (2 2 ), on the schematic diagram; the example is the light body 4, on the circuit board (22 = Up to two, on the two fixed posts (142) of the ^ and the combination of the dazzle and the square to one. 2) The light guiding structure of the creation is on the plane of the body (... A number of light grooves ("), in the figure of the ring body M297876 embodiment of the light groove (13) and the body (1 〇) axially perpendicular design and radial configuration 'and each light groove (" The pitch of the crucible is designed to be close to the light-emitting element (2Q)_the smaller one-face ("", and conversely, the distance between the optical centers (1 3)- away from the light-emitting element (2〇) is larger. Formed as a dense section ("...the light element (2 丄) of the light bulb (2丄) along the body (")

After the wide shot, the light and the light groove ("...face contact can form a bright light on the display surface (1 1 ); since it is close to the body (1 〇) of the light-emitting element (2 0), 1 = strong' And this area is a sparse section with a large spacing between the optical grooves (13), 2) 'so' exhibits a brightness with a constant intensity, and is far away from the optical element (20) @body (1 0) 'The light is weak, but because of the dense surface section (13 work) where the distance between the light grooves (13) is small, the light is weak and the denser light groove (13) acts. (1) The brightness formed by the location is very uniform with the brightness of the dense surface 9 ("D is formed: very close to 'below' the entire body (丄〇) at the display surface (丄1). See also Wu Guanyu, another embodiment used for this creation, that is, its -1QA) is straight, with _lighting elements\, A^ body (1〇A)-side planes (UA) at its two ends. ) is provided with a light groove =) 'light groove (" Μ 较 较 较 较 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 131 segment( "2A), in the end of the two-end faceted section (132 A) with a light-emitting element (2QA) and towards the center of the dense 3ia) M297876 knows and shoots, thereby designing the light-emitting element slot (1 3 A The configuration design can show uniform brightness on the body (1 1 A) u) display surface through the aperture A)

Therefore, the light guiding structure of the present invention is applied to the illuminating body at the lamp or decoration of the vehicle, so that the extremely clear and uniform light can be used to indicate the position or provide a decorative effect, and the warning of the car can be improved and the warning can be improved. effect.
