A lighting apparatus includes a circuit board, a lighting element and a lens structure. The lighting element is disposed on the circuit board. The lighting element includes a lighting top surface and a lighting lateral surface adjoined to the lighting top surface and the circuit board. The lighting top surface has a center and an optical axis passing through the center. The lens structure covers the lighting element to receive a light from the lighting element. The lens structure includes an outer surface having a total reflection portion and a light outgoing portion surrounding the total reflection portion. The optical axis passes through the total reflection portion. The total reflection portion is configured to totally reflect a portion of light from the center. The light outgoing portion is configured to allow another light emitted from the center to leave away from the lens structure. |
