Embodiment Construction

[0013] Figures 1A-1B Two exemplary lighting modules operable to increase the area illuminated by an illumination source are depicted. Figure 1A Lighting module 100A is depicted. Illumination module 100A includes a substrate 101 (such as a PCB) and an illumination source 102 (eg, an array of light emitting diodes, lasers, vertical cavity surface emitting lasers, and / or any of the foregoing exemplary light sources). The illumination source may be in electrical contact with the substrate 101 through electrical contacts 103 (eg, wires, vias, solder bumps). Illumination source 102 may emit light 104 of a particular wavelength range (eg, light imperceptible to humans, such as infrared light). Additionally, the illumination source 102 may be operable to emit modulated light, such as intensity modulated light implemented in time-of-flight applications. Light 104 of a specific wavelength range is emitted from an illumination source 102 with a first intensity distribution 105 over a...

Abstract

The present disclosure relates to illumination modules operable to increase the area illuminated by an illumination source, such as a vertical cavity surface emitting laser or a light emitting diode. Such an illumination module includes a substrate having electrical contacts, an illumination source electrically connected to the substrate, a collimating assembly operable to collimate light generated from the illumination source, a collimating assembly operable to translate over an area Light translation components and mask components. In various implementations, the illumination source may be relatively small in area, thereby reducing the cost of the illumination module. In some cases, some implementations of the lighting module can be used to acquire three-dimensional data, while in other cases, some implementations of the lighting module can be used in other applications that require projecting light.

Description

technical field [0001] The present disclosure relates to lighting modules including optical assemblies. Background technique [0002] Mobile devices typically include optoelectronic modules with corresponding illumination sources. In general, there is significant pressure to reduce the cost of such photovoltaic modules. The cost of the photovoltaic module is generally related to the area on which the illumination source is implemented. For example, an array of Vertical Cavity Surface Emitting Lasers (VCSELs) is implemented on a chip with a specific diameter. In order to increase the illuminated area of ​​the VCSEL array, or to increase the area illuminated by the VCSEL, the diameter of the VCSEL chip is increased. However, the cost of this diameter increase can be very expensive. Contents of the invention [0003] The present disclosure describes lighting modules that increase the area illuminated by an illumination source without increasing the diameter of the illumin...
