| 摘要 |
A light emitting lamp is provided to reduce fabrication costs, to simplify assembling processes and to improve a light condensing efficiency by using an optical lens structure composed of a plurality of optical lenses. A light emitting lamp includes a plurality of light emitting chips and an optical lens. The optical lens(90) includes a plurality of optical lenses(50) corresponding to the light emitting chips. Each optical lens includes a light condensing portion for refracting light in a predetermined angle range and a total reflection portion. The plurality of optical lenses are made of the same material. The plurality of optical lenses are formed like one-piece structure.
