Description
Technical field
The utility model relates to field of illumination lamp technology, particularly relates to a kind of desk lamp module.
Background technology
Desk lamp is the light fixture that room lighting is conventional, and what in desk lamp, play illuminating effect is desk lamp module, is the part sending light source.And desk lamp to work the light fixture write as people, its performance requirement is higher, particularly the optics degree aspect of desk lamp module, requires particularly exquisite.China has put into effect the national standard (GB/T9743-2008) of a " read-write operation post lamp behaviour requires " specially, wherein the requirement to desk lamp module illuminance is set forth in the inside, be recorded in detail in this part of national standard file: when eyes move towards bright place from dark environment, can feel dazzling, at this moment the pupil of eyes can reduce at once reduce the light injected to adapt to bright environment.This is natural physiological adaptability phenomenon.Therefore, we require that desk lamp illumination on the table should be relatively more uniform, and field of illumination should cover the area of read-write operation, otherwise, read when writing and cause the size being engraved in during eyes and ceaselessly regulating pupil the visual line of sight intraoral illumination of eyes is uneven, easily cause the fatigue of vision.Method of testing is for the center of circle with the upright projection of the geometric center of light fixture light-emitting window point; be positioned at the dead ahead of eyes, within the scope of the projection of eyes side, from the radius distance in the center of circle be 300mm one third sector shaped within; AA level illumination should be greater than 500lx, and A level illumination should be greater than 250lx; Radius distance from the center of circle is the one third sector shaped by within the fan-shaped region cut down above of 500mm, and AA level illumination should be greater than 300lx, and A level illumination should be greater than 150lx.Uniformity of illuminance (maximum/minimum) in each region must not be greater than 3.This standard defines two level of illuminations.If need work the longer time under desk lamp, the grade that manufacturer can recommend user to use illumination level higher.
As illustrated in fig. 1 and 2, about the test of above-mentioned illumination: with the upright projection of the geometric center of light fixture light-emitting window point for the center of circle, be positioned at the dead ahead of eyes, within the scope of the projection of light fixture, from the radius distance in the center of circle be 500mm one third sector shaped in, with 30 ° for interval, radius carries out illumination photometry, test interval is 100mm, comprises the center of circle, and the uniformity of illuminance (maximum/minimum) in each region must not be greater than 3.
But the uniformity of illuminance of the desk lamp module of prior art is generally all difficult to the standard reaching above-mentioned national defined, causes people easily to produce fatigue in the process using desk lamp, adverse influence is brought to the eyes of people.
Summary of the invention
In view of this, the utility model discloses a kind of desk lamp module, and the uniformity of illuminance that can contribute to desk lamp illumination range is up to state standards, thus it is conducive to the eyes protecting user.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
