Description
Technical field
The utility model relates to illuminators more particularly to a kind of penetrometer cold light source to needle headlamp.
Background technique
The needle penetration of pitch is to indicate the soft or hard degree of pitch and consistency, the ability for resisting failure by shear.Predetermined temperature (such as
25 DEG C) under, the depth representing with the standard needle of definite quality (such as 100g), in stipulated time (such as 5s) interior injection bitumen samples
(0.1mm is 1 needle penetration).
Bitumen needle forcemeter is the special instrument for detecting Asphalt Penetration.Before the test, it is necessary to by penetration test
The needle point of needle is narrowly focused towards the surface of sample, so headlamp is the essential component of instrument.
Since pitch heat can soften, thus the requirement to headlamp be irradiated to the temperature of the light of asphalt surface cannot be too
Otherwise height will affect the result of test.
Currently, general penetrometer, using common shot-light or incandescent lamp as headlamp, since this headlamp exists
Often heat transfer is made to illuminated asphalt surface during naked eyes are to needle with certain heat when illumination
The opposite local pitch fever of needle point softens, to influence the accuracy of penetration test result.
In not better method, user or shortens to time of needle as far as possible or abandon using this seed type
Headlamp, to needle under conditions of natural light or indoor illumination.Result of which often will affect the accuracy to needle,
And then influence the result of test.
Utility model content
The utility model is to provide a kind of penetrometer cold light source to needle headlamp to solve above-mentioned deficiency.User
When to needle, headlamp will not generate heat, and the local pitch that illuminating ray will not make the surface needle point of bitumen samples opposite generates heat, becomes
It is soft, the length to the needle time is not limited yet, it is ensured that the accuracy of needle, and then ensures the accuracy of penetration test result.
The above-mentioned purpose of the utility model is realized by technical solution below: a kind of penetrometer cold light source shines needle
Bright lamp, including shell, reflector and lamp holder, the case nose are equipped with housing, are equipped with reflector in shell, reflector center is set
There is cold light source lamp, cold light source lamp is mounted on lamp holder, and lamp holder is fixed in the shell of reflector central back, and lamp holder, which is connected with, leads
Line.
Further, it is cased with metal hose outside the conducting wire, metal hose is connect with outer casing back.
Further, the conducting wire is the conducting wire powered for cold light source to needle headlamp；The metal hose is cold light source
To the installing pipe of needle headlamp；The lamp holder is cold light source to needle headlamp mounting rack；The reflector is that cold light source shines needle
The reflection unit of bright lamp；The cold light source lamp is the positive white LEDs lamp that power is 1W；The shell is cold light source to needle headlamp
Fluorescent tube；The housing is transparent protective shield of the cold light source to needle illuminating lamp tube.
The utility model compared with prior art the advantages of be:
1, to the quality-advantage of needle:
The penetrometer cold light source of the utility model is irradiated to the temperature of specimen surface to needle headlamp when making user to needle
It is extremely low, it can be neglected, improve the condition of local microenvironment when to needle, relieve mental handicape of the user to needle when, make pair
The quality of needle is effectively ensured, and the inaccuracy of test result caused by due to needle accurate sexual deviation is avoided.With obvious
To needle quality-advantage.
2, the quality-advantage of headlamp:
Since the light source that the utility model uses is LED light, according to data introduction, service life of LED light 50000 hours with
On, and the service life of incandescent lamp, common shot-light, about at 1000 hours or so, the service life of LED light is incandescent lamp, common shot-light service life
50 times or more, substantially increase penetrometer to the quality of needle headlamp.With significant headlamp quality-advantage.
3, the advantage of overall mass:
Due to using LED light as cold light source to the light source of needle headlamp, service life is greatly improved.Originally by white heat
The quality problems sharp fall of the headlamp generation of lamp, common shot-light composition, improves the quality level of complete machine, reduces and sell
The workload and after service cost serviced afterwards.Advantage with overall mass.
