This is to make the distribution of light to be uniform.

The degree of concentration of light emitted from the first LED element 141 is determined by the ratio (L2 / L1) of the length L1 of the first guide hole 155a and the length L2 of the second guide hole 155c. Can be proportional. The ratio L2 / L1 between the length L1 of the first guide hole and the length L2 of the second guide hole may be approximately 1.5 to 10.

When the ratio (L2 / L1) of the length (L1) of the first guide hole and the length (L2) of the second guide hole is greater than 10, the effect that light emitted from the first LED element 141 is concentrated increases, but the second The thickness of the guide portion 155 in which the guide hole 155c is formed may be thickened.

When the ratio (L2 / L1) of the length (L1) of the first guide hole and the length (L2) of the second guide hole is less than 1.5, there is a problem that the effect of focusing light emitted from the first LED element 141 is reduced. Can be.
