Abstract

The present invention disclosed a lighting system for controlling the controlled interval in accordance with the face.Including the blue light LED, the first light, the first mirror, the second lapse, and the second lens installed in the shell along the same light shaft in the shell, the shutter is installed at the second light, the shutter and the shutter drive circuitConnect, the light emitted by the blue light LED is controlled by the first light, the first lens refraction, the second lantern and the shutter inlet light control, and the second lens refraction.The present invention has realized intermittent lighting of the target plane, which can light up and detect the activation of optical genetic cells, and can be convenient to disassemble, which is convenient for components to check, replace and system expansion or reorganization. It also reduces the lighting time of lighting time.The cost of control is widely used.

Description

technical field [0001] The invention belongs to the field of optical system design, and in particular relates to an illumination system for controllable intermittent and uniform illumination of an illuminated surface. The uniform illumination optical system is constructed and an electronic control module is added to realize the corresponding illumination time control function. Background technique [0002] In genetic cell activation assays, it is necessary to obtain intermittent and uniform illumination of the target plane. Among existing commercial products, there is no product that combines intermittent lighting with uniform lighting. Therefore, we combine Cora lighting with intermittent control to form a simple and practical intermittent uniform lighting system. [0003] In this practical invention, we use the single-chip microcomputer to output rectangular waves to drive the opening and closing of the shutter, so that intermittent lighting can be obtained on the illumin...
