Laboratory ventilation cabinet LED illumination lamp set

Abstract

The invention relates to the technical field of ventilation cabinet illumination lamps, in particular to a laboratory ventilation cabinet LED illumination lamp set. The illumination lamp set comprisesa background lamp, a front pillar lamp, a top lamp and a power supply system, wherein an intelligent switch is arranged between the front pillar lamp and the power supply system, an intelligent switch is arranged between the top lamp and the power supply system, infrared transmitters are arranged at two sides of the lower end of a ventilation cabinet body, infrared receivers are arranged at two sides of the lower end of a sliding door, and the intelligent switches, the infrared transmitters and the infrared receivers are electrically connected with a single-chip microcomputer respectively. According to the illumination lamp set, when the infrared receivers receive signals sent by the infrared transmitters, the single-chip microcomputer receives the signals sent by the infrared receivers and controls the corresponding induction switches to turn off the front pillar lamp and the top lamp; in an experiment state, the illumination lamp set cannot perform perpendicular incidence towards the outer side of the cabinet body, so that both eyes of an experimenter are effectively protected, and the situation that light pollution influences observation of an experiment process by the experimenter is avoided; and in a non-experimenter state, only the background lamp in the illumination lamp set works, so that energy is saved.

Description

technical field [0001] The invention relates to the technical field of fume hood lighting lamps, in particular to an LED lighting lamp for laboratory fume hoods. Background technique [0002] The laboratory fume hood is the most concentrated area of ​​laboratory pollution, and it is also the key part of laboratory pollution control. In particular, experiments that are explosive, flammable, and endangering human health and safety must be carried out in the fume hood. One of the necessary conditions for testing in a fume hood, especially at night. [0003] LED is a cold light source, and semiconductor lighting itself does not pollute the environment. Compared with incandescent lamps and fluorescent lamps, the power saving efficiency can reach more than 90%. Under the same brightness, the power consumption is only 1 / 10 of that of ordinary incandescent lamps and 1 / 2 of that of fluorescent tubes. If 50% of our traditional lighting is replaced by LED, the electricity saved in ou...

Problems solved by technology

Simultaneously, the lighting lamp of the laboratory fume hood in the prior art is generally installed in the area that the naked eye of the experimenter can look directly at, while illuminating the fume hood, also can bring great burden to the eyes of the experimenter, light pollution Seriously, need a light that can illuminate the entire fume hood while being in a position where the experimenter won't look directly
