Abstract

The utility model discloses an LED lighting device for a measuring microscope, which is composed of a light source seat, a tail cover, pressing rings, a high-intensity light emitting diode, an aspheric condenser, a spacing ring, ground glass, a polyvinyl chloride isolation mounting flexible wire and screw nails. After the high-intensity light emitting diode (4) and the polyvinyl chloride isolation mounting flexible wire (9) are welded, the high-intensity light emitting diode and the polyvinyl chloride isolation mounting flexible wire are tightly screwed and fixed in the tail cover (2) by the pressing ring. The tail cover (2) is sheathed in the light source seat (1), and is fixed by the screw nail (10). The aspheric condenser (5) is arranged in the light source seat (1) at the front surface of the high-intensity light emitting diode (4), and is fixed by the spacing ring (6) on an inner hole of the light source seat (1) and the screw nail (11) on the side surface. The ground glass (7) is arranged in the light source seat (1) at the end part of the spacing ring (6), and is fixed by the pressing ring (8). The LED light source of the utility model belongs to the semiconductor stage-contacting and transition light emission, and the utility model has the advantages of small heat generation, long service life, small energy consumption, no splash, canonical lighting surface, and simple and firm installation, is easy to ensure image quality and is suitable for a measuring microscope.

Description

Measuring microscope LED lighting device

Technical field: the utility model relates to lighting device, particularly a kind of measuring microscope LED lighting device.

Background technology: former video measuring microscope series, digital measurement microscope series, all be to use osram lamp or halogen tungsten lamp to do light source, its shortcoming is:

1. power consumption is big, and light efficiency is not high, and osram lamp belongs to the plain edition light source, and filament is arranged at random, dress school instrument difficulty (picture element is difficult to guarantee good);

2. bulb heating, the transformer heating, energy loss is big and convert heat energy to, and is unfavorable to the instrument stabilizer sex work;

3. the sputter of bulb wall tungsten is serious, so that new and old bulb intensity transmitance difference is very big;

4. fragile, sputter is serious, and the life-span is short, and consistance is poor;

5. bulb is day by day exhausted, and the trend of eliminating is obvious.

Summary of the invention: the purpose of this utility model is to provide a kind of measuring microscope LED lighting device, utilizes this lighting device that the goniometer eyepiece light-source illuminating system of tool microscope series of products is greatly enhanced.

Formation of the present utility model: by light source base, tail-hood, trim ring, the high strength light emitting diode, aspherical condenser, spacer ring, frosted glass, polyvinyl chloride insulation is installed by flexible cord and screw is formed, after high strength light emitting diode 4 and polyvinyl chloride insulation are installed flexible cord 9 welding, be tightened in tail-hood 2 with trim ring 3, tail-hood 2 is sleeved in the light source base 1, and it is fixing by screw 10, in the light source base 1 of high strength light emitting diode 4 fronts, aspherical condenser 5 is installed, fixing by spacer ring 6 on light source base 1 endoporus and the screw on the side 11, frosted glass 7 is installed in the end of spacer ring 6 light source base 1, fixing with trim ring 8.

Compared with the prior art, the utility model has the advantages that:

To touch order transition luminous 1.LED light source belongs to semiconductor, generate heat little, the life-span is long, energy consumption is low, no sputter;

2. the light-emitting area standard very easily guarantees picture element;

3. install simple and firm;

4. application is wide, universal fast, the anxious source of goods.

Description of drawings: Fig. 1 is the utility model structural representation; Fig. 2 is the A place enlarged drawing of Fig. 1.

1. light source bases among the figure, 2. tail-hood, 3. trim ring, 4. high strength light emitting diode, 5. aspherical condenser, 6. spacer ring, 7. frosted glass, 8. trim ring, 9. polyvinyl chloride insulation is installed flexible cord, 10. screw, 11. screws.

Embodiment: as shown in Figure 1 and Figure 2, after high strength light emitting diode 4 and polyvinyl chloride insulation are installed flexible cord 9 welding well, be tightened in tail-hood 2 with trim ring 3, behind aspherical condenser 5 threading light source bases 1 endoporus, block with two spacer rings 6, cover the frosted glass 7 of balanced light beam again, screw with threaded trim ring 8, in order to guarantee the stability of aspherical condenser 5, hold out against with screw 11, light source base 1 and tail-hood 2 connect by screw 10, and entire body is attached on the instrument by polyvinyl chloride insulation installation flexible cord 9 and gets final product.

Claims

1. measuring microscope LED lighting device, by light source base, tail-hood, trim ring, the high strength light emitting diode, aspherical condenser, spacer ring, frosted glass, polyvinyl chloride insulation is installed by flexible cord and screw is formed, it is characterized in that: after high strength light emitting diode (4) and polyvinyl chloride insulation are installed flexible cord (9) welding, be tightened in tail-hood (2) with trim ring (3), tail-hood (2) is sleeved in the light source base (1), and it is fixing by screw (10), in the light source base (1) of high strength light emitting diode (4) front, aspherical condenser (5) is installed, fixing by spacer ring (6) on light source base (1) endoporus and the screw (11) on the side, frosted glass (7) is installed in the end light source base (1) of spacer ring (6), fixing with trim ring (8).
