Abstract
The utility model relates to a stereoscopic microscope light, which consists of a light cover, a light source and a power source. The light source adopts 1 to 2 Omega type cathode fluorescent light tubes; the power source is divided into an AC-CD converter and a DC-AC converter; the AC-CD part is separated from the main body of the light. When two light tubes are adopted, the circuit is provided with strong and weak file light adjusting switches so as to make the luminous intensity adjustable to satisfy the different lighting requirements of the stereoscopic microscope. The utility model takes the cathode fluorescent light tube as the light source and has the advantages of small volume, long service life, small electric power consumption, and adjustable luminous intensity.
Description
Technical field
The utility model relates to a kind of lighting lamp of stereographic microscope.
So the illumination of stereomicroscope all has its special requirement because how the influence that is subjected to working distance of microscope and space installs etc. illumination, the brightness of lamp, volume.The light source of existing lighting lamp of stereographic microscope has the incandescent lamp of employing, Halogen lamp LED or fiber illuminated cold light source to make shot-light, but shot-light shines with pointolite, and shade is arranged during illumination, simultaneously, the incandescent lamp colour temperature is too low, and the Halogen lamp LED life-span is short, heating is high, and fiber illuminated cold light source price height uses all undesirable; There is the three-color fluorescent lamp of employing to do light source, very high because stereomicroscope operating distance and space are limited to the volume requirement of light fixture, but the three-color fluorescent lamp fluorescent tube is thicker.Be difficult to do small and exquisitely, it is adjustable that three-color fluorescent lamp is difficult to make illumination again; Have a plurality of white light-emitting diodes of employing to do light source, but the illumination of light emitting diode is not high.
Summary of the invention
The purpose of this utility model is to provide a kind of new illuminating lamp for stereomicroscope.
Lighting lamp of stereographic microscope of the present utility model is made up of lamp housing, light source and power supply three parts, lamp housing top is a round mounting interface, the periphery of this mounting interface has several that connecting screw is installed, so that this illuminating lamp is mounted on the stereomicroscope; The lamp housing bottom is ring-like light source base, and the rear portion of lamp housing is a board box; Light source is installed on the light source base; Feature of the present utility model is that light source is 1～2 cathode fluorescent tube; Power supply comprises AC-DC converter and DC-AC converter two parts, and AC-DC converter and lamp housing are separated and be positioned on the power lead, and the DC-AC converter is located in the board box at lamp housing rear portion.
Aforesaid lighting lamp of stereographic microscope of the present utility model, wherein said DC-AC converter is preferably made electronic transformer, and its output parameter is generally: frequency 25～45KHz, voltage 800～1200V, working current 5～10mA.Lamp housing is preferably made Ω shape, simultaneously, also makes Ω shape as the cathode fluorescent tube of light source.Usually, be two as the cathode fluorescent tube of light source, and on board box, be provided with strong and weak shelves dimmer switch, to satisfy requirement the different light degree.
Cold-cathode fluorescence lamp has the light efficiency height, long service life, fluorescent tube is tiny, characteristics such as diameter has only several millimeters, and power consumption is few are because fluorescent tube is tiny, so illumination is not high, so cold-cathode lamp was used for back lighting more in the past, the illuminating lamp use is not generally directly done in mark illumination or indirect fornix illumination, decorative lighting etc.The utility model people finds stereomicroscope in work and research operating distance and is made lighting lamp of stereographic microscope through evidence with cold-cathode fluorescence lamp and can be had enough illumination usually below 150mm.
The illuminating lamp of stereomicroscope, be preferably made circular arc type, the structure of cathode fluorescent tube is made up of electrode, inlead and glass tube, if owing to be subjected to the influence of electrode that fluorescent tube is processed into annular, can only be made in lamp pin on the different planes, maybe can only make bigger " C " type of breach, and also be difficult to be processed into smooth-going arc near the lamp pin place.The utility model is made Ω shape to cathode fluorescent tube, then can overcome above-mentioned shortcoming, is convenient to install.Simultaneously just because of cathode fluorescent tube is tiny, thus can do light fixture very small and exquisitely, for stereomicroscope stays the more work space.The utility model also adopts two to differ in size, and the similar Ω shape cathode fluorescent tube of shape is installed on the light source base side by side, and two tubes are worked simultaneously, can increase illumination; Can control by dimmer switch again simultaneously, make a tubes bright, another tubes does not work, and it is adjustable flexibly to reach the illumination stepping, to satisfy the different illumination needs of stereomicroscope.
Because the space of stereomicroscope is limited, for light source provides power unit.The utility model is made two parts with DC-AC to power supply.AC-DC partly placed separate with the illuminating lamp main body beyond the illuminating lamp lamp housing, DC-AC partly makes in the board box that electronic transformer places the lamp housing rear portion.At first the alternating current of civil power (110/220V) is converted to low pressure (12V) direct current by the AC-DC part, this low-voltage DC is input to DC-AC part in the board box at lamp housing rear portion by power lead again, partly changes into electric current and the voltage that is fit to cathode fluorescent tube work by DC-AC.
Because the cathode fluorescent tube volume is little, and the tube current of work makes the DC-AC part can make very little electronic transformer for a short time, and because AC-DC partly leaves the illuminating lamp main body, institute so that whole illuminating lamp main body can do compact more.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
