Abstract
The utility model discloses a darkroom lamp for bio-experiments, and relates to the technical field of experimental illumination. The experimental lamp comprises a base, wherein the base is installed with a rotatable Light-Emitting Diode (LED) cold light source; a control box is used for regulating the brightness of the LED cold light source; a digital control circuit is arranged in the control box; a pedal switch, which is connected with the digital control circuit and used for controlling on and off of the LED cold light source is arranged out of the control box; and the control box is equipped with a grounding terminal. The overall darkroom lamp for bio-experiments utilizes a separated structure of the LED cold light source, the control box for illumination regulation and the pedal switch, so that an operator can use the lamp more flexibly and conveniently; in addition, the grounding terminal can effectively shield discrete electromagnetisms.
Description
Technical field
The utility model relates to the experiment lighting technical field, specifically is a kind of Bioexperiment dark room lamp.
Background technology
Existing Bioexperiment dark room lamp is mainly used in the usefulness that microscopical local lighting in the Bioexperiment darkroom is provided, and has two kinds of led light sources of red illumination and white-light illuminating available.At present, the light on and off of Bioexperiment dark room lamp is to realize through the switch that is arranged on the base, when the laboratory technician is doing when experiment, and the inconvenient light on and off of removing to control led light source with hand.Owing to there are not safeguard procedures, the discrete electrical magnetic compass in the laboratory often influences the brightness of Bioexperiment dark room lamp.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of Bioexperiment dark room lamp, and during microscopical local lighting, the operator is easy to operate, has eliminated the influence of discrete electromagnetism in realizing the Bioexperiment darkroom.
The utility model is realized with following technical scheme: a kind of Bioexperiment dark room lamp, comprise base, and be installed in rotary LED cold light source and the control cabinet that is used to regulate the brightness of LED cold light source on the base, be provided with digital control circuit in the control cabinet; Control cabinet is provided with one outward and is connected the floor push that is used to control the light on and off of LED cold light source with digital control circuit; Control cabinet is provided with ground terminal.
The beneficial effect of the utility model is: the separate type that the whole LED of employing cold light source, illumination are regulated control cabinet and floor push makes operator's use more flexible; Being provided with ground terminal effectively shields discrete electromagnetism.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the utility model structural representation;
Fig. 2 is the digital control circuit theory diagram;
Fig. 3 is digital control circuit figure.
Among the figure: 1, LED cold light source; 2, coiled pipe; 3, base; 4, control cabinet; 5, floor push.
The specific embodiment
As shown in Figure 1, the Bioexperiment dark room lamp has a base 3, and rotary LED cold light source 1 is installed on base 3, and a coiled pipe 2 is installed on base 3, and LED cold light source 1 is installed in the upper end of coiled pipe 2, and described base 3 is a clamper.Control cabinet 4 is used to regulate the brightness of LED cold light source 1, is provided with digital control circuit in the control cabinet 4; Control cabinet 4 is outer to be provided with one and to be connected the floor push 5 that is used to control 1 light on and off of LED cold light source with digital control circuit; Control cabinet 4 is provided with ground terminal.Described LED cold light source 1 comprises red and white two kinds of led light sources, and red LED cold light source and White LED cold light source are not interchangeable, otherwise will cause fault and damage.
As shown in Figure 2, digital control circuit comprises brightness regulating circuit, the ON-OFF control circuit that is connected with brightness regulating circuit and D.C. regulated power supply, and brightness regulating circuit is connected with the LED cold light source through lead.
As shown in Figure 3, D.C. regulated power supply adopts three terminal regulator WY17824, for the LED cold light source provides voltage; White lamp source of stable pressure 33V, red light source of stable pressure 24V.
ON-OFF control circuit is made up of monopulse generator, power switch and ON-OFF control circuit, and when the firm power-on of complete machine, power switch breaks off, no-voltage output; The LED matrix extinguishes, and when sending a pulse (floor push is pressed once), ON-OFF control circuit is opened power switch, and voltage output is arranged; The LED matrix is bright secretly by brightness regulating circuit decision (voltage is adjustable), when floor push is pressed one time again, sends out a pulse again, and control circuit breaks off power switch; No-voltage output, LED goes out, when sending a pulse again; Again power switch is opened ... By that analogy, the light on and off of control LED matrix.
Brightness regulating circuit is the circuit that can regulate output voltage, and maximum is output as source of stable pressure output voltage (the LED matrix is the brightest), and minimum is output as 2/3 (the LED matrix is extinguished) of source of stable pressure power supply.The LED matrix is made up of the connection in series-parallel of 72 LED high brightness luminescent pipes in the present embodiment.
Specific operation process is following:
1, according to regulating correct light source socket and the floor push socket of connecting of control cabinet rear board sign, ground terminal is carried out effective grounding through connecting lead, power-line plug is connected with AC220V, 50Hz supply socket.
2, each connection of inspection correctly also connects reliable.
3, LED cold light source, illumination adjusting control cabinet and floor push are placed correct position.
4, turn on the power switch, power supply indicator is bright.
5, regulate the brilliance control knob, the brightness of LED cold light source will change thereupon.This moment, gently stepping on, floor push got final product if the LED cold light source does not have light.Being adjusted to correct position according to instructions for use brilliance control knob gets final product.
6, using of floor push: floor push is Digital Circuit Control, steps on the light on and off that can realize light source and changes automatically, will not be placed on the pedal of floor push by pin always.
7, finish using, the powered-down switch, and power-line plug and supply socket are separated.
