A lighting device includes a board, first light emitting elements and second light emitting elements. The first light emitting elements emit lights in a first spectral range. The second light emitting elements emit lights in a second spectral range. The second spectral range is narrow than the first spectral range. The first light emitting elements are disposed in at least one first area of the board, and the second light emitting elements are disposed in second areas of the board. The at least one first area and the second areas are alternatively arranged on the board.

Lighting device with regions of differing spectral ranges

The present invention provides a voltage control method for controlling a power supply. The voltage control method comprises the following steps: obtaining a present output voltage value associated with a present gain value; obtaining a predetermined output voltage value associated with a predetermined duty ratio; calculating a target gain value, corresponding to the predetermined duty ratio, according to a gain value formula; performing a weight calculation on the present gain value and the target gain value for generating a buffer gain value; and setting an output voltage command according to the buffer gain value. Wherein the buffer gain value is between the present gain value and the target gain value.

An automatic mounting and demounting device and system for a motor testing platform, adapted to enable a control host to control automatic mounting and demounting between an axle of a motor under test and an axle of a testing apparatus, includes a mobile platform and a positional information sensing member. The control host controls the mobile platform according to positional information generated by the positional information sensing member, such that a carrier for carrying the motor under test is automatically driven to a corresponding position to thereby effect alignment and connection or separation of the axle of the motor under test and the axle of the testing apparatus. Therefore, preparation for the motor dynamics testing is automatically carried out effectively and correctly, thereby reducing the time and manpower required for testing-related preparation.
