Abstract
The utility model provides an electric torch type luminous digital universal meter, which is formed by that a lighting part and a luminous display part are additionally arranged on the basis of the original digital universal meter. The utility model comprises a lighting lamp, a light emitting element with an LED, a lighting power supply, a controlling key, etc., and thus under the condition of insufficient illumination, the point measured and the digital display can be seen clearly. The utility model has simple structure, convenient operation, convenience for carrying and one object with dual purposes.
Description
The utility model relates to a kind of survey instrument, particularly with the noctilucence digital multimeter of torch.
It is of a great variety and constantly obtain upgrading aspect measurement structure for existing digital multimeter, but existing all kinds of digital multimeter has a weak point, promptly, be difficult to see measured point and show reading, bring great inconvenience to surveying work in the place of daylighting deficiency.
The purpose of this utility model provides a kind of torch noctilucence digital multimeter makes the people still can normal operation under the situation of daylighting deficiency.
Realization of the present utility model is to add illumination and noctilucence display part on the basis of original digital multimeter, its element comprises bulb, light emitting diode, three-position switch and mains lighting supply, mains lighting supply and multimeter power supply are separate, and light emitting diode is powered by mains lighting supply.
Below in conjunction with drawings and Examples structure of the present utility model is further described.
Fig. 1 is the structural representation of the utility model illumination, noctilucence display part.
By accompanying drawing as can be known the utility model on the basis of digital multimeter, added bulb (2), snoot (1), three-position switch (3), mains lighting supply (5) and several light emitting diodes (4), bulb (2), switch (3) power supply (5) independent design is on the bottom of multimeter, the digital multimeter that can join a series of different measuring functions, mains lighting supply (5) is separate with the multimeter power supply, one grade of control light emitting diode (4) of three-position switch (3), second gear closes power supply, third gear control illuminating lamp (2) and light emitting diode (4) act on simultaneously, the available two joint No.5 cells of mains lighting supply (5), illuminating lamp (2) can be screw type, chromium plating parabolic concentrator cover is to the light boundling, make it the direction of propagation and enough illuminance preferably, the bias light of LCDs is produced by light emitting diode (4), can produce soft uniform bias light by the diffusion mating plate on it, even make the multimeter reading can both be clear and legible at night, LCDs adopts the transmission-type reflector plate to make the substrate watchcase and makes with plastics.
From the above the utility model has utilized the clearance spaces in the universal meter bottom, and the overall structure of his-and-hers watches need not be done big change, can be used with a series of digital multimeter, have simple in structure, volume is little, is easy to processing, easy to use, be easy to carry, the advantage of a thing dual-purpose.
Claims (3)
1, a kind of torch noctilucence digital multimeter comprises measure portion and shell, it is characterized in that also comprising an illuminating lamp (2), light emitting diode (4), three-position switch (3) and mains lighting supply, the mains lighting supply (5) that is powered at illuminating lamp (2) and light emitting diode (4) is independent of the multimeter power supply.
2, torch noctilucence digital multimeter according to claim 1 is characterized in that LCDs has a transmission-type reflecting piece substrate.
3, torch liquid light digital multimeter according to claim 1 is characterized in that having a chromium plating to throw scene snoot (1).
