The light condensing performance by the convex portion 66 is determined depending on the
The transmittance and the reflectance of the convex portion 66 depend on the incident angle of the convex portion 66, and the reflected light propagates through the light guide plate 61.
The characteristics of 61 are not impaired. Thus, the guide light device 1
Even if the length in the depth direction is shortened, since the front luminance of the surfaces of the display panels 41 and 51, that is, the light in the normal direction of the surfaces of the display panels 41 and 51, the light use efficiency is improved.

Fluorescent lamp that guides light to the farthest direction from 45 and 55
The emitted light spread in the axial direction of 45 and 55 is refracted in the normal direction of the display panels 41 and 51.

A facing plate 73 made of an acrylic resin is provided facing the convex portion 72, and the opposite plate 73 has the longitudinal sides of the fluorescent lamps 45 and 55 on the surface opposite to the surface facing the convex portion 72. A plurality of triangular grooves 74 having a substantially triangular cross section and having an axial direction parallel to the direction are formed side by side in parallel. The triangular grooves 74 of the light direction changing means 71 transmit light from the light guide plate 61 to the display panel 4.
The light is refracted in the normal direction of 1, 51 to improve the light use efficiency as in the case shown in FIG.

According to the ninth aspect of the present invention, the display means on the front surface is attached so as to close the opening of the fixture body, and the light guide of the display means on the front surface is irradiated with light from the light source to guide the light. Since the light incident on the light body is refracted and output to the display means, even if the electric component is stored in the electric component storage portion inside the appliance body, the optical characteristics are not adversely affected, such as being shaded, so that the electric component is not affected. The versatility is improved by mounting the frame part on the ceiling surface or the back surface on the wall surface, etc., and the light direction conversion means improves the brightness and uniformity of the light irradiation direction. Can be improved.

According to the illuminating device of the tenth aspect, in addition to the illuminating device of any one of the first to ninth aspects, the display means is attached so as to close the opening of the appliance body, and the light guide plate of the display means is attached to the light guide plate. By irradiating light from the light source and reflecting the light guided by the diagonally notched surface of the concave cylinder, the configuration is simplified by reflecting toward the display surface, and the device is simplified. Even if electrical components are stored in the electrical component storage section inside the main unit, there is no adverse effect on optical characteristics such as shadows, so the degree of freedom in arranging electrical components is increased, and the frame part is attached to the ceiling surface Or, the versatility can be improved by attaching the back surface to a wall or the like.

According to the lighting device of the eleventh aspect, in addition to the lighting device of the tenth aspect, the light source has a lamp current of 4 m.
Since the control device adjusts the current of the storage battery so that the lamp current becomes 4 mA to 10 mA, the lamp can be appropriately turned on.

According to the lighting device of the twelfth aspect, in addition to the lighting device of the tenth or eleventh aspect, the control means includes:
Since the lamp effective current is controlled by changing the on / off duty, the current is appropriately controlled with a small current loss.
The discharge time of the storage battery can be efficiently lengthened, and if the discharge time does not need to be lengthened, the capacity of the storage battery can be reduced, so that the storage battery and the whole can be reduced in size.

According to the guide light device of the thirteenth aspect, since the guidance display panel provided in the light guide of the lighting device of any one of the first to twelfth aspects is provided, the respective effects can be obtained. it can.
