In the conventional light emitting diode lamp 1, the light emitting diode element 3 is fixed to the tip of one of the two lead terminals 2a and 2b, and the light emitting diode element 3 and the other lead terminal 2b are fixed.
And a thin metal wire 4 are connected between them. The tip portions of the lead terminals 2a and 2b in which the light emitting diode element 3 is incorporated are sealed by a dome-shaped lens portion 5 made of a translucent resin. The lens portion 5 is rotationally symmetric with respect to the optical axis A perpendicular to the bottom surface 5a, and the light emitting diode element 3 is arranged substantially on the optical axis A. Therefore, the directivity of the light emitting diode lamp 1 is reduced. As shown in FIG.
It is uniform over the entire circumference, and its range is relatively narrow due to the converging action of the lens unit 5.

である。FIG. 13 shows a collective light emitting diode display device composed of a plurality of light emitting diode lamps 1 as described above. In this collective type light emitting diode display device 10, for example, a substrate 12 in which a plurality of light emitting diode lamps 1 are two-dimensionally arranged is housed in a cylindrical casing 11 having a bottom, and a cable for supplying power from the bottom of the casing 11 is provided. 13 is led out, and the surface side of the substrate 12 is filled with a resin 14. As shown in FIG. 14, the directivity of such a collective type light emitting diode display device 10 is substantially the same as that of the light emitting diode lamp 1 which is its element.

ａ，２ｂを折り曲げ加工して、基板に実装している。However, the conventional light emitting diode lamp 1 and the collective type light emitting diode display device 10 as described above have the following problems. That is, in the conventional light emitting diode lamp 1, since the optical axis A of the lens portion 5 is perpendicular to the bottom surface 5a thereof, a sufficient luminous intensity can be obtained when viewed from the optical axis A (front side). However, sufficient brightness cannot be obtained when viewed from an oblique direction. Therefore, in such a case, the lead terminal 2 is so arranged that the optical axis a of the lens portion 5 is directed obliquely.
A and 2b are bent and mounted on a substrate.

れないという問題点がある。For example, FIG. 15 is a partial sectional view of an electric device using the light emitting diode lamp 1 as an indicator. In the figure, reference numeral 6 is a substrate on which electric parts such as the light emitting diode lamp 1 and the connector 7 are mounted, and 8 is a reflector for guiding the light emitted from the light emitting diode lamp 1 to the light emitting surface 8a. Due to the layout design of the electrical components that make up the electrical equipment, electrical components such as the connector 7 may be disposed below the light emitting surface 8a. In such a case, the light lead-out hole 8b of the reflector 8 is Since it is formed in an oblique direction, the lead terminals 2a and 2b of the light emitting diode lamp 1 are bent and mounted on the substrate 6. The processing of such lead terminals is complicated and lowers the production efficiency, and since the bending accuracy is not so high, there is a problem that stable directivity cannot be obtained.

Therefore, in the case of a collective type light emitting diode display device that can be seen from a wide range, as shown in FIG. 16, the light emitting diode lamp 1a mounted on the peripheral portion of the substrate 12 is so arranged that the optical axis of the light emitting diode lamp 1a faces outward. By bending the lead terminals of FIG.
Wide directivity as shown in. However, as described above, the bending process of the lead terminal is complicated, and stable directivity cannot be obtained.

ある。Further, as shown in FIG. 18, in the case of a matrix display device 15 constructed by arranging light emitting diode lamps or collective type light emitting diode display devices in a matrix, an observer can see the display device 15 from the front. There are few things to look at, and most of them look up from below. Therefore, if the conventional light emitting diode lamp 1 or the collective type light emitting diode display device 10 using the same is mounted in a horizontal state to form the matrix display device 15, sufficient brightness cannot be obtained for an observer looking up from below. There is a drawback in that the mounting angle must be adjusted.

を偏らせることができる。FIG. 2A is a vertical sectional view taken along line XX of FIG.
(B) is a YY vertical sectional view of FIG. As shown in FIG. 2A, the light emitted from the light emitting diode element 3 is
By the action of the lens 21, the light is converged and emitted in the direction along the inclined optical axis A. In this embodiment, the light emitting diode element 3 is eccentrically mounted on the side opposite to the tilt direction of the optical axis A. Incidentally, in the conventional light emitting diode lamp 1 shown in FIG. 11, the light emitting diode element 3 is mounted on the center of the lens portion 5. In the present embodiment, the light emitting diode element 3 is eccentrically attached so that the light emitted from the light emitting diode element 3 is totally reflected by the inclined surface of the lens portion 21 as shown by the symbol L in FIG. This is to reduce the amount of light that escapes from the inclined surface by directing the light in the direction of the optical axis A, thereby increasing the light emission efficiency in the optical axis direction. As shown in FIG. 2B, there is no deviation in the light emission direction in the YY cross section. This is because the optical axis A is decentered along the line XX in FIG. Therefore, if the optical axis A is tilted in both X and Y, it is possible to deviate the light emission direction in the YY cross section.

FIG. 3A shows the directivity in the XX section, and FIG. 3B shows the directivity in the YY section. As described above, according to the present embodiment, the light can be emitted in any direction by setting the inclination angle of the optical axis A of the lens unit 21 as desired.
