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.
