Multi-waveform multi-frequency stroboscopic dimming device

Abstract

The invention relates to a multi-waveform multi-frequency stroboscopic dimming device, which comprises a controller, a cage and a power supply. The power supply is connected with the controller via a power line; the output end of the controller is provided with four wires for building connection with the cage; the case is provided with a protective net; a shading cloth is arranged outside the protective net; the controller is provided with an air switch and a touch screen; the controller is provided with three output modes: a sine wave frequency modulation and lightening mode, a square wave frequency modulation and lightening mode, and a non-strobing lightening mode, the sine wave frequency modulation range is 1 to 20Hz, the square wave frequency modulation range is 1 to 11Hz, and the lightening range in the three output modes is 1 to 20 levels. The multi-waveform multi-frequency stroboscopic dimming device has the advantages that a sine wave stroboscopic light and a square wave stroboscopic light can be simulated, switching can be carried out at any time, experiment selection is facilitated, blank of sine wave and high frequency in the research on the development of an eyeball can be filled, the frequency range is wide, and the controller can simulate strobe as high as 1 to 20 Hz.

Description

technical field [0001] The invention relates to the technical field of animal experiment equipment, in particular to a multi-waveform and multi-frequency strobe dimming device. Background technique [0002] At present, the etiology of myopia is still a worldwide problem, and a major breakthrough in myopia research in recent decades is the successful establishment of animal models of myopia in the 20th century, and obtained some insights into the mechanism of myopia occurrence and development in animal models. The research results further clarified the mechanism of myopia occurrence and development. Using animal models of myopia to study myopia has many advantages, for example, some studies that cannot be carried out on humans can be transferred to animals. The establishment of animal models makes the in-depth study of myopia possible, and provides an animal basis for the development of new drugs to delay the development of myopia in the future.

Problems solved by technology

[0006] However, the above-mentioned strobe dimmer has the following disadvantages: 1. The frequency of the strobe light is low, and the highest frequency can only reach 5Hz, 10Hz; 2. When the strobe reaches the limit, it is easy to crash; 3. The strobe dimmer passes The time relay and other time alternately light and dark. From the perspective of the stroboscopic method, it is only a square wave stroboscopic, which is relatively simple; 4. The frequency and light intensity of the stroboscopic dimmer are controlled by the corresponding knobs. The size makes the experimental error larger and the operation is cumbersome

And about this stroboscopic dimming device, there is no report yet
