A low-voltage alternating current-based LED light with built-in cooling and automatic or manual dimming. As it is self-cooled with fan failure protection, the light can be safely run in conditions that are near-hostile to its operation, with little possibility of damage. The light is movable along the XY axes of a grid system and can be either fixed in position in the Z axis or can be movable up and down the Z axis. The light can be equipped with either manual dimming using a standard potentiometer, or with automatic dimming via sensors and local network connectivity. The device prevents line-voltage electric shocks as the input voltage is low-voltage AC; in embodiments, about the same voltage as a doorbell, and the input current is 3 A. The device is also self-cooled, and will shut down if its fan is not running so as to prevent thermal overloads.

A system and method for pre-aligning a light beam in a spectroscopic measuring device such as a pump-probe device prior to conducting a measurement procedure is provided, which eliminates the need for monitoring or modification of the beam trajectory through adjustments of elements transmitting the beam (e.g., mirrors) over the course of a measurement process.

Embodiments of the present disclosure provide methods and apparatuses for detecting an ambient light illuminance and for computing a correction coefficient, and an electronic device. The method for detecting an ambient light illuminance includes: filtering ambient light based on a monochromatic channel, such that a quantum effect curve of the filtered light matches a spectral luminous efficiency curve; and performing photoelectric detection on the filtered light to obtain an illuminance level of the ambient light. In solutions of the embodiments of the present disclosure, the photoelectric detection may be equivalent to obtaining an illuminance level of light by convolutional computation based on a spectral luminous efficiency curve, and therefore, when a quantum effect curve for a monochromatic waveband obtained by filtering ambient light based on a monochromatic channel matches the spectral luminous efficiency curve, a reliable spectral luminous efficiency curve can be obtained with a small computing workload.
