  Next, the first reflecting member 13 will be described in detail with reference to FIG. The first reflecting member 13 emits the light beams LL1, LL2, and LL3 emitted from the LEDs 11a, 11b, and 11c arranged in a line in the vertical direction on the circuit board 12 in the substantially horizontal direction to the circuit board 12. Are provided with first, second, and third reflecting mirrors 13a, 13b, and 13c that respectively reflect the display means 10 disposed so as to be positioned in a substantially vertical direction, and the reflecting mirrors 13a and 13b are provided. , 13c are arranged along the arrangement direction of the LEDs 11a, 11b, 11c. Then, the first reflecting member 13 and each of the LEDs 11a, 11b, and 11c and the reflecting portions are directed from the first reflecting mirror 13a located at the upper end (one end) toward the third reflecting mirror 13c located at the lower end (the other end). The reflecting mirrors 13a, 13b, and 13c are disposed so that the distances d1, d2, and d3 with the mirrors 13a, 13b, and 13c are gradually shortened (d1> d2> d3).

  Moreover, the 1st reflection member 13 is each reflection surface 13a1, 13b1, 13c1 of each reflection mirror 13a, 13b, 13c toward the 3rd reflection mirror 13c located in a lower end from the 1st reflection mirror 13a located in an upper end. The widths W1, W2, and W3 are set to be gradually reduced (W1> W2> W3).

  In addition, the first reflecting member 13 includes an arrangement interval between the first LED 11a corresponding to the first reflecting mirror 13a and the second LED 11b corresponding to the second reflecting mirror 13b, and the second reflecting mirror 13b. The arrangement interval between the corresponding second LED 11b and the third LED 11c corresponding to the third reflection mirror 13c is made equal, and this interval is A, and the first reflection mirror 13a and the second reflection mirror 13b The distance between the centers of the irradiation widths of the light L1 and L2 reflected by the display means 10 with respect to the display means 10 is B, and the light L2 and L3 reflected by the second reflection mirror 13b and the third reflection mirror 13c. When the distance between the centers of the respective irradiation widths with respect to the display means 10 is C, it is set so as to satisfy the relationship of A> B, A> C, B = C. The array interval A is the interval between the light emission centers (centers on mounting) of the LEDs 11a, 11b, and 11c. Further, the intervals B and C correspond to the respective reflection mirrors 13a, 13b, and 11c when the light emission centers of the LEDs 11a, 11b, and 11c and the center positions of the respective widths W1 to W3 of the reflection mirrors 13a, 13b, and 13c are substantially matched. 13c is the center interval of the irradiation widths of the lights LL1 to LL3 irradiated to the display means 10 by 13c.

  The display means 10 includes a display 10a made of a liquid crystal display element and a light diffusion plate (light diffusion member) 10b disposed behind the display 10a. The display 10a displays at least various vehicle information such as a vehicle speed, an engine speed, and a remaining fuel value based on a control signal output from a control means (not shown) constituted by a microcomputer. The light diffusing plate 10b diffuses the lights LL1 to LL3 irradiated from the reflecting mirrors 13a, 13b, and 13c, respectively, and supplies the diffused light to the display 10a.

  The operation of the first reflecting member 13 will be described with reference to FIGS. It is assumed that the LEDs 11a, 11b, and 11c used in this embodiment have substantially the same directivity angle (directivity characteristics). FIG. 7 shows the combined luminance distribution X1 in the illumination means 10 when the first reflecting member 13 is not used. The mounting structure of the LEDs 11a, 11b, and 11c on the circuit board 12 is based on mounting layout problems such as the space required for mounting the LEDs 11a, 11b, and 11c and the dimensions of the LEDs 11a, 11b, and 11c themselves. , 11c, and a space A between the light emission centers of the LEDs 11a, 11b, 11c in a state including the gap S. Therefore, in the case where the first reflecting member 13 is not used, in the luminance distributions x1, x2, and x3 of the lights LL1 to LL3 emitted from the individual LEDs 11a, 11b, and 11c, the interval A between the emission centers having the strongest light intensity is obtained. Due to widening due to problems in the mounting layout (because the valleys between the luminance distributions x1 ′, x2 ′, and x3 ′ become large), the variation in light intensity in the combined luminance distribution X of the individual LEDs 11a, 11b, and 11c D1 becomes conspicuous, and unevenness in the brightness of the light supplied to the display means 10 is generated, and good display light L from the display means 10 cannot be obtained.

  Therefore, the above-described problem can be solved by using the configuration of the first reflecting member 13. That is, when the first reflecting member 13 is used, as is apparent from the combined luminance distribution X2 of the illumination unit 10 shown in FIG. 8, the reflecting mirrors 13a, 13b, and 13c are set to A> B, A> C, B = C (see FIG. 6) is provided so that the luminance distributions x1 ′, x2 ′, and x3 ′ of the individual LEDs 11a, 11b, and 11c reflected from the reflecting mirrors 13a, 13b, and 13c are brought closer to each other. That is, since the degree of overlap of the luminance distributions x1 ′, x2 ′, and x3 ′ can be increased (because the valleys between the luminance distributions x1 ′, x2 ′, and x3 ′ can be reduced), the individual LEDs 11a and 11b. , 11c in the combined luminance distribution X2, the light intensity variation D2 is also reduced, and unevenness in the luminance of the light supplied to the display means 10 can be suppressed. It is possible to obtain light L.

  FIG. 9 is an example showing the actual structure of the first reflecting member 13. Note that the same or corresponding portions as those shown in FIG. 6 are denoted by the same reference numerals, and detailed description thereof is omitted. The first reflecting member 13 is each reflecting surface which is a flat surface portion having a predetermined angle (45 degrees) for irradiating the display means 10 with each light LL1, LL2, LL3 emitted from each LED 11a, 11b, 11c. 13 a 1, 13 b 1, 13 c 1, and metal reflective films 13 a 2, 13 b 2, 13 c 2 made of, for example, aluminum are formed on the respective plane surfaces 13 a 1, 13 b 1, 13 c 1, so that each reflection mirror 13 a, 13 b, 13c. A connecting portion 13d is provided between the reflecting mirrors 13a, 13b, and 13c, and a concave portion 13e for preventing light diffusion by the lights LL1, LL2, and LL3 is provided in the connecting portion 13d. The first reflecting member 13 is obtained by obtaining a basic structure having the reflecting surfaces 13a1, 13b1, 13c1, a connecting portion 13d, and a concave portion 13e by an injection molding method using a mold, and then forming each reflecting surface 13a1, 13b1, 13c1 on each reflecting surface 13a1, 13b1, 13c1. It can be obtained by forming the metal vapor deposition films 13a2, 13b2, and 13c2 by vapor deposition.

  Such a head-up display device A is disposed in the case body 16 to display at least the traveling information of the vehicle 1 and the display light L disposed behind the display means 10 and serving as the vehicle information. Is generated from the display means 10, the first reflecting member 13 that reflects the light LL (LL 1, LL 2, LL 3) emitted from the light source 11 toward the display means 10, and the display means 10 The second reflection member 14 that reflects the display light L, and the third reflection that enlarges the display light L reflected by the second reflection member 14 and projects the enlarged display light L outside the case body 16. The member 15 is provided.

  Therefore, in the head-up display device A, by disposing the first reflecting member 13 between the light source 11 and the display means 10, the heat radiating member 17, the circuit board 12, the light source 11, and the display in the case body 16 are provided. Since the light source 11, the circuit board 12, and the heat radiating member 17 can be arranged on the side surface of the case body 16 without arranging the means 10 in the vertical direction, the head-up display device A can be reduced in size and thickness. Can be realized. Further, the heat dissipating fins 7a in the heat dissipating member 17 can be directed not to the lower side of the case body 16 but to the side of the case body 16, and the air permeability to the heat dissipating fins 7a is improved. It becomes possible to enhance the heat dissipation effect. The heat dissipating member 17 is arranged on the case body 16 so that the outside air passes through the heat dissipating fins 17a on the side of the case body 16 from the lower side of the case body 16 to the upper side or from the upper side to the lower side. Furthermore, the heat dissipation efficiency can be increased.

  The first reflecting member 13 includes individual reflecting mirrors 13a, 13b, and 13c so as to correspond to the respective LEDs 11a, 11b, and 11c of the light source 11 including the plurality of LEDs 11a, 11b, and 11c. The display means 10 is arranged so as to be positioned substantially perpendicular to the arrangement direction of the LEDs 11a, 11b, 11c arranged in a row, and the lights LL1, LL2, emitted from the LEDs 11a, 11b, 11c. The reflecting mirrors 13a, 13b, and 13c for irradiating the display unit 10 with LL3 are arranged along the arrangement direction of the LEDs 11a, 11b, and 11c, and are positioned at the lower end from the first reflecting mirror 13a that is located at the upper end. The distances d1, d2, and the distances between the respective LEDs 11a, 11b, and 11c and the respective reflecting mirrors 13a, 13b, and 13c as the third reflecting mirror 13c is moved. Each of the reflecting mirrors 13a, 13b, 13c is provided on one reflecting member 13 so that 3 is gradually shortened, and from the first reflecting mirror 13a located at the upper end to the third reflecting mirror 13c located at the lower end. The widths W1, W2, and W3 of the reflecting surfaces 13a1, 13b1, and 13c1 of the reflecting mirrors 13a, 13b, and 13c are gradually decreased as they go.

  The arrangement interval between the first LED 11a corresponding to the first reflection mirror 13a and the second LED 11b corresponding to the second reflection mirror 13b is A, and the first reflection mirror 13a and the second reflection mirror are set to A. The distance between the centers of the respective irradiation widths of the light L1 and L2 reflected by the light 13b on the display means 10 is B, and the lights L2 and L3 reflected by the second reflecting mirror 13b and the third reflecting mirror 13c. When the distance between the centers of the respective irradiation widths with respect to the display means 10 is C, it is set so as to satisfy the relationship of A> B, A> C, B = C.

  Therefore, since the degree of overlap of the luminance distributions x1 ′, x2 ′, x3 ′ of the individual LEDs 11a, 11b, 11c reflected from the reflecting mirrors 13a, 13b, 13c can be increased, the individual LEDs 11a, 11b, 11c are increased. The light intensity variation D2 in the combined luminance distribution X2 is also reduced, and the unevenness of the brightness of the light supplied to the display means 10 can be suppressed, so that the good display light L from the display means 10 can be obtained. It should be noted that the center interval B of each irradiation width with respect to the display means 10 of each light L1, L2 reflected by the first reflection mirror 13a and the second reflection mirror 13b, and the second reflection mirror 13b and the third reflection. Although the center interval C of each irradiation width with respect to the display means 10 of each light L2, L3 reflected by the mirror 13c is set to B = C, it depends on the layout relationship between each reflection mirror 13a, 13b, 13c and the display means 10. May satisfy the relationship B> C.

  The reflecting mirrors 13a, 13b, and 13c are reflecting surfaces 13a1, 13b1, and 13c1 having predetermined angles for irradiating the display means 10 with the lights LL1, LL2, and LL3 emitted from the LEDs 11a, 11b, and 11c. Even if the first reflecting member 13 has a complicated structure, the reflecting mirrors 13a, 13b2, and 13c2 are formed by injection molding using a mold. Since 13b and 13c can be configured integrally, the manufacturing process of the head-up display device A is not complicated.

  The first reflecting member 13 is provided with a connecting portion 13d between the reflecting mirrors 13a, 13b, and 13c, and a recessed portion 13e is provided in the connecting portion 13d. Accordingly, the reflection mirrors 13a, 13b, and 13c can be integrally formed by providing the connecting portion 13d, and the light beams LL1, LL2, and LL2 emitted from the LEDs 11a, 11b, and 11c can be provided by providing the recess 13e. Since unnecessary light when LL3 reflects can be prevented from diffusing, the display light L emitted from the display means 11 can be improved.

  Further, the display means 10 can diffuse each light LL1, LL2, LL3 by disposing the light diffusion plate 10b on the light receiving surface side of each light LL1, LL2, LL3. Light L can be obtained.

  In the embodiment of the present invention, the head-up display device A that reflects the display light L in the direction of the user 4 on the windshield 2 of the vehicle and displays the virtual image V is described as an example of the vehicle display device. However, the vehicle display device according to the present invention may be one in which the present invention is applied to a vehicle display device using a projection member different from the windshield 2 that reflects the display light L toward the user. .

  In the embodiment of the present invention, the LEDs 11a, 11b, and 11c in the light source 11 are arranged in a line in the vertical direction in the case body 16, but the arrangement direction of the light emitting elements in the present invention is as follows. As long as the effect that the heat dissipation efficiency of the heat dissipating member 17 can be reduced and the heat dissipating member 17 can be reduced is not limited to the arrangement direction (vertical direction) in the above-described embodiment.
