6results about How to "Guaranteed light intensity" patented technology

The embodiment of the present specification provides an optical sensor. The optical sensor comprises a microlens array composed of at least two microlenses and a sensor chip; the sensor chip is provided with photosensitive elements corresponding to the microlenses respectively; the microlens converges the light irradiated to the microlens to the photosensitive element corresponding to the microlens; the microlenses in the microlens array located at different field positions on the sensor chip have different lens structures, so as to improve the ratio of the illumination intensity of the light received by the photosensitive element corresponding to the microlens at the edge position to the illumination intensity of the light received by the photosensitive element corresponding to the microlens at the center position; and the photosensitive element is used for generating a corresponding photosensitive electrical signal according to the illumination intensity of the received light. The above-mentioned optical sensor improves the relative illumination of the array as a whole, and further improves the presentation effect of the finally obtained image.

This utility model discloses a temperature and humidity regulating laboratory specimen preservation device, belonging to the field of laboratory equipment technology. It includes a cabinet with rotating doors on both sides, and also includes a temperature sensor, a humidity sensor, a small compressor, an ultrasonic humidifier, a condenser dehumidifier, a heater, and a controller for intelligent control. This utility model, by arranging temperature, humidity, and light sensors inside the preservation cabinet, allows for comprehensive and accurate collection of temperature, humidity, and light intensity data within the cabinet. Combined with an intelligent control module, a temperature and humidity regulation module, and a light regulation module, it achieves precise temperature and humidity regulation, ensuring sufficient light intensity for the specimens and maintaining a suitable preservation environment. The controller's intelligent control module automatically controls the temperature and humidity regulation module according to preset temperature and humidity standard ranges, eliminating the need for frequent manual operation and improving the efficiency and stability of specimen preservation.

This utility model discloses a safety helmet for underground mining operations. The helmet includes a helmet body, an inner liner fixedly attached to the lower side of the helmet body, a cushioning sponge installed inside the helmet body, a fixed shell fixedly attached to the helmet body, a lighting lamp fixedly attached to the front side of the fixed shell, and a lampshade installed on the front side of the fixed shell. The lighting lamp is located inside the lampshade. A curved cavity is provided inside the fixed shell, and a transparent strip is provided within the curved cavity. The transparent strip is slidably connected to the outside of the lampshade. This utility model uses the output shaft of a motor to drive a rotating roller on the left side to rotate. The two rotating rollers are connected by gear transmission, and the two rotating rollers rotate in different directions. The transparent strip rotates counterclockwise, causing the transparent strip, free of dust inside the fixed shell, to move to the outside of the lampshade. By changing the position of the transparent strip, the light emitted by the lighting lamp is prevented from being obstructed, ensuring the brightness of the lighting.

The utility model belongs to the field of fire rescue, and provides a portable boat lighting system which comprises a front lamp holder, a plurality of side lamp holders and a tail lamp holder, and through the arrangement of the front lamp holder, the side lamp holders and the tail lamp holder, a lighting lamp set can be fixedly used along with a boat and also can be detached to be worn and used by rescue workers. And the protection grade, the safety, the illumination intensity and the illumination time of the lamp are guaranteed. The side lamp holder is made of professional boat rubber repairing paste and does not need to be disassembled after rescue is completed at ordinary times. The front lamp holder is made of stainless steel and detachably connected with the lamp, and the lamp is easy to detach. And the boat tail lamp holder is fixed with the engine hood, so that boat navigation and rescue actions are not influenced. The whole set of lighting system is easy to install, and fixed use and carrying use are combined, so that the system is convenient to disassemble, charge, store and transport. The water area rescue device can effectively improve the multifunction and light weight of devices carried by firemen on a water area rescue site, save the preparation time of the rescue devices, and improve the rescue speed.
