Light-emitting diodes are solid-state light sources and have a long service life, so red-and-yellow light-emitting diodes have gained attention as light sources that can be replaced with a longer interval and that exhibit high reliability over a long period of time, and have already been able to obtain the required light intensity. Are being used in signal lights instead of conventional incandescent lamps.

性等の各条件を満足する必要がある。However, in the case of a light emitting diode, it is common to use surface light emission in which a large number of minute light emitting diodes are arranged. In the case of using the light emitting diode, it is necessary to satisfy each condition such as light distribution, the number of light emitting diodes to be mounted, a position or a temperature characteristic.

下する特性を有しているため留意する必要がある。[0004] In particular, it is necessary to pay attention to the temperature characteristics because the light emitting diode has a characteristic that the current flowing therethrough is restricted at a high temperature and the luminous intensity is thereby reduced.

ってしまう。[0005] As described above, in a light-emitting diode module in which a large number of light-emitting diodes are arranged in a plane as described above, the heat generated by the adjacent light-emitting diodes tends to accumulate the light-emitting diodes and the temperature tends to rise. In particular, when arranged in a plane, the central portion has many adjacent light emitting diodes, so heat storage is promoted and the temperature rises, and in the peripheral portion, the temperature rises because heat is radiated from a place with few adjacent light emitting diodes. As a result, the luminous intensity in the central portion of the light emitting diode module is lower than that in the peripheral portion, and the desired luminous intensity and light distribution cannot be obtained.
