A lighting system and a projection device with enhanced functionality includes a light source in the lighting system for emitting first light, a first wavelength selection structure, and a second wavelength selection structure. The first wavelength selection structure includes a wavelength selection portion for transmitting the first light in a first target wavelength and a first light-transmitting portion for transmitting the first light. The light emitted then from the first wavelength selection structure is defined as second light. The second wavelength selection structure receives the second light and applies a supplementary portion for transmitting the second light in a second target wavelength and a second light-transmitting portion for transmitting the light. The light emitted from the second wavelength selection structure is adjustable as to colors, as to low or high color saturation, and as to low or high brightness of the projection image.

A device as a light-emitting for a projector. The projector includes a light-emitting module and a first lens array positioned at one side. The first lens array includes a number of first lenses arranged in parallel along a first direction. The first lens array is configured to receive source light. A second lens array is positioned at a side of the first lens array. The second lens array includes a number of second lenses arranged in parallel along a second direction. The second lens array receives first collimated light from the first lenses and emits second collimated light which is of even light-spot density and uniform brightness.

A lens module for autofocus of a camera in passive mode includes a lens barrel containing a first lens, a second lens, a pressure sensor, an image sensor, and a processor. In the passive autofocus mode, the first lens is located at a first end of the lens barrel and moves within the lens barrel when a distance to a target object changes. The pressure sensor between the first and the second lenses senses both pulling and pushing pressures which the first lens applies. The image sensor is adjacent to an end of the lens barrel and is behind the first and second lenses. The processor can apply formulas to calculate a distance between the target object and the lens module.
