Abstract
Substantially cylindrical supporting units are formed at both sides of a lens. The supporting units are to adjust the separation distance between the lens and the surface of a substrate depending on the height dimension of a light emitting diode mounted on the substrate from the substrate face when the lens body is fixed to the substrate. A cylindrical convex part is formed at a part of the tip face of the supporting unit in a concentric fashion relative to the supporting unit, and a cylindrical positioning unit is formed at a part of the tip face of the convex part in a concentric fashion. The positioning unit functions as a member for positioning when the substrate and the lens body are fixed to each other.

-11. (canceled)
A lens body having a lens for condensing light from a light source wherein the lens is attached to face a predetermined face,
- comprising:
- an adjusting unit for adjusting an attachment interval between the predetermined face and the lens.
A lens body having a lens for condensing light from a light source wherein the lens is attached to face a predetermined face,
- comprising:
- an adjusting unit capable of maintaining an equal interval between the lens and the light source by adjusting an attachment interval between the predetermined face and the lens depending on a type of the light source.
A light source unit comprising a substrate, on which a light emitting device is mounted, and a lens for condensing light from the light emitting device, comprising:
- the substrate comprises an adjusting member for adjusting a separation distance between the lens and the surface of the light emitting device to be substantially constant regardless of a height of the light emitting device.
