Abstract
A light emitting module includes a light-emitting unit, a wavelength converting element and an optical convergent element for partially or totally converting the wavelength of incident light. The light-emitting unit includes a light-emitting element which emits a first light, the wavelength converting element and an optical convergent element disposed in a light path of the first light from the light-emitting element, such that the first light is converted into a particular light at a specific area with a reduced beam diameter after passing through the optical convergent element and before entering the wavelength converting element.
Claims15
A light emitting module, comprising:
- a light-emitting unit having a light-emitting element emitting a first light in a wavelength λ1;
- an optical convergent element, disposed in a light path of the first light from the light-emitting element, such that the first light of the wavelength λ1, after passing through said optical convergent element, is converged to a specific area of a second light in a wavelength λ1;
- and
- a wavelength converting element, disposed in a light path of the second light from the optical convergent element, the wavelength converting element having a wavelength converting material and an incident plane, so that the second light in the wavelength λ1, after entering the incident plane and the wavelength converting element, is converted to a third light in a wavelength λ2.
