However, in the present invention, the transparent cover 4 includes the end surface portion 4a. In order to make it transparent, it is formed in a substantially cap shape by integral molding of a transparent member such as resin or glass.

  And when attaching to the edge part of the said support | pillar 2, the said transparent cover 4 is attached through packing (not shown) etc., and the appropriate waterproof process is performed with respect to the installation environment. Is preferred. By doing in this way, when installing in a garden etc., the said light emission part 3 will not be directly exposed to raindrops.

  The light emitting unit 3 includes a reflector 31 having a shape that can be attached to the inner diameter of the transparent cover 4 by an appropriate means, for example, a shape viewed from the top surface or the back surface, and a light source that is, for example, an LED lamp. 32, an inner lens 33, a half mirror 34 having a substantially circular shape having a diameter substantially the same as the inner diameter of the transparent cover 4, and the reflection / direct lens 35, similar to the reflector 31.

  Next, the configuration of the light emitting unit 3 will be described in more detail. A plurality of light emission ports 31a penetrating the reflector 31 from the back surface to the surface thereof are provided at appropriate positions such as the outer peripheral portion of the reflector 31. A light source 32 such as a white light emitting diode is attached to the back side of each of the light exit ports 31a, that is, the surface on the support column 2 side.

  A reflection / direct-light lens 35 made of a transparent resin or the like is attached to the surface side of the light exit port 31a, and light passing from the light source 32 through the light exit port 31a to the surface side. Is captured, and light is irradiated toward the decorative pattern portion 31 b formed to protrude to the surface side of the reflector 31.

  At this time, an inner lens 33 formed in a ring shape or the like and cut with a decorative pattern lens cut 33a is provided above the reflector 31, and the reflective / direct lens 35 is provided with the light. The inner lens 33 is directly irradiated with a part of the light from the light source 32 passing through the emission port 31a.

  The inner lens 33 is provided with an appropriate number of mounting legs 33b, and the reflector 31 and the inner lens 33 are integrated with the reflector 31 by an appropriate means such as adhesion, fitting, or welding. Has been done. Moreover, in said structure, it is preferable from the surface of the improvement of the decoration effect etc. that the said reflector 31 is made into the thing with the high glossiness by performing the lustrous process by metal vapor deposition etc., for example.

  In addition to the configuration described above, in the present invention, as shown in FIG. 4, a half mirror 34 is provided further above the inner lens 33, and the half mirror 34 includes the transparent cover. 4 on the top surface 4a and the inner lens 33. At this time, the inner lens 33 is preferably shaped such that the inner lens 33 side becomes a concave mirror having an appropriate curvature.

  In the lighting device 1 of the present invention, as in the case of the conventional example, an automatic flasher that automatically flashes when the surroundings become dark or automatically detects that a visitor is approaching. It is free to install a proximity detection device or the like that is lit on.

  Next, functions and effects of the illumination lamp device 1 according to the present invention will be described. First, when the light source 32 is turned on, light from the light source 32 provided on the back surface of the reflector 31 of the light emitting unit 3 passes through the light exit port 31a, and a part thereof is captured by the reflection / direct lens 35. Then, the decorative pattern portion 31b formed on the reflector 31 is illuminated.

  The light not captured by the reflection / direct-light lens 35 travels straight, reaches the inner lens 33, and shines by being diffused by a lens cut 33a applied to the inner lens 33. Therefore, if the number of the light sources 32 provided is increased, the decorative pattern portion 31b of the reflector 31 and the lens cut 33a of the inner lens 33 will shine with substantially uniform brightness.

  However, in reality, if it is attempted to shine evenly due to the shape of the decorative pattern portion 31b or the shape of the lens cut 33a, the number of light sources 32 is increased, resulting in an increase in cost or consumption. This causes problems such as an increase in power.

  Therefore, in the present invention, the half mirror 34 is provided. For example, in the case of the half mirror 34 having a reflectance of 50%, half of the light diffused by the decorative pattern portion 31b and the lens cut 33a is again obtained. Irradiation is directed toward the decorative pattern portion 31b and the lens cut 33a.

  Therefore, uneven illumination in the light emitting unit 3 such as the decorative pattern portion 31b and the lens cut 33a is reduced, and this reduced state becomes visible to the viewer through the half mirror 34 and the transparent cover 4. The display quality on the decorative surface will be improved. Further, in the daytime when the surroundings are brighter, the half mirror 34 of the illuminating lamp device 1 of the present invention reflects the external light and shines, and can produce an aesthetic appearance different from that at night.

  In FIG. 1, the transparent cover 4 is shown as a simple cap having a certain thickness. However, the present invention is not limited to this, and the reflector 31 and It is possible to provide a lens cut in a range that does not impair the appearance of the inner lens 33, for example, to improve the aesthetics of the illuminating lamp 1 itself when not lit.

  FIG. 2 shows an example of the shape of the reflector 31 according to the present invention. The reflector 31 is provided with light emission ports 31a at nine locations near the outer periphery, as described above. In addition, a light source 32 is provided on the back side of each light exit port 31a, and a reflection / direct lens 35 (not shown) is attached on the front side, and protrudes from the center of the reflector 31. The decorative pattern part 31b to be formed is formed.

  Therefore, when the light source 32 is turned on, the light from the reflection / direct-light lens 35 shines with various luminances due to differences in the light receiving area, the light receiving angle, etc. The decorative pattern portion 31b appears. As is clear from the above description, the shape and brightness of the decorative pattern portion 31b can be freely set by the designer, so that, for example, a pattern such as a family crest can be displayed according to the customer's request. Is possible.

  FIG. 3 shows a state in which the inner lens 33 is combined with the reflector 31. The decorative pattern portion 31b provided in the central portion of the reflector 31 shines, and the inner portion is above the decorative pattern portion 31b. The lens 33 is also brilliant, and the stereoscopic effect is further improved, and the beauty is also improved accordingly.

  In addition, by combining the reflector 31 and the inner lens 33 in this way, the light emitting port 31a, the reflection / direct-light lens 35, and other parts that are not directly related to the function as the illumination lamp are caused by the inner lens 33. Since it is covered when viewed from above, the viewer does not feel uncomfortable.

  FIG. 4 shows a state in which the light emitting section 3 such as the light source 32, the reflector 31, the inner lens 33, the half mirror 34, the half mirror 34, and the transparent cover 4 are assembled.
