体に形成するようにしても良い。Several similar light-emitting element lamps 23 are also attached to the blue plate 22b forming the floor of the prayer body 22, as shown in the figure. The anode thorn 23m and cathode terminal 23b of each light-emitting element lamp 23 are electrically connected to the outer lead 2 led out from the back surface of the substrate 22b of the light-emitting body 22, as shown in FIG. . Here, the light emitter 2
The shape of the light emitting element lamp 23 is not limited to a regular square pyramid shape, but may be any shape as long as it can contain several light emitting element lamps 23 with a large number of β1. The light-emitting element lamp 23 is attached to the light-emitting body 22
It is also possible to form a light emitting body with a three-dimensional structure by several sleeves of surface light emitting elements without adding more light emitting elements.

有する。As a result, a wide area can be illuminated. In other words, compared to conventional lamps in which a large number of light emitting element lamps are simply installed in one plane, it is possible to illuminate with much higher brightness and with wider directivity. 1. The light source is composed of a light emitting element lamp 23, so if a notification of 20 mA is made, the power consumption is about 3 W.
Compared to tungsten fibers with an α-increased feed angle, they consume much less gravity, have high reliability, and have the same long lifespan.
