しまうという欠点もあつた。 For example, incandescent lamps and LED (light emitting diode) lamps are used as light sources for this type of indicator light device. Since LED lamps are significantly inferior in brightness to incandescent lamps, they cannot be used as a unit, so they have no meaning.As a result, they have been devised to increase brightness by arranging many LED lamps. Figures 8, 9, and 10
The lamp unit type shown in FIG. 1, FIG. 11, and FIG. 12 is known. Introduction Figure 8,
In FIG. 9, this lamp unit includes a rectangular wiring board 52 on which a large number of rectangular LED mode resins 51 are arranged, and a plug-in base fixed to the back side of the wiring board 52 and connected to each LED mode resin 51. 53, a rectangular cylindrical illumination frame body 50
It is designed to fit inside and be stored. Next, in FIGS. 10 and 11, this lamp unit includes a disk-shaped wiring board 55 on which a large number of LEDs 54 are arranged, and a screw-in type that is fixed to the back side of the wiring board 55 and connected to each LED. As in the case of FIGS. 8 and 9, the lamp 56 is configured to be fitted and housed in each cylindrical illumination frame 50. However, in the case of the lamp unit constructed in this way, as shown in FIGS. 8 and 9, in order to hold the lamp unit, a slight twist is required after inserting the cap 53 into a holder (not shown). Therefore, the dimensions of the wiring board 52 must be made smaller than the inner dimensions of the lighting framework 50, and as a result, even if the central part of the lighting framework 50 has a predetermined brightness, the surrounding area becomes dark. The drawback was that the overall brightness was insufficient. Next, the first
Regarding the examples shown in FIGS. 0 and 11, since the base 56 is of a screw type, the wiring board 55 is naturally disk-shaped, and as a result, the light does not reach the four corners of the illumination frame 50 during lighting, so it is not evenly distributed. The drawback was that it was not possible to obtain a high level of brightness, resulting in uneven light. In addition, as a means for eliminating the above-mentioned drawbacks, both of them have an illumination frame body 5, which is not shown in the drawings.
A diffuser plate is installed inside the 0 to diffuse light in order to obtain uniform brightness, but in order to obtain uniform brightness, the amount of diffusion must be increased, and if the amount of diffusion is increased, Another drawback was that the light attenuated, making the whole thing dark.
