Description
Technical field
The utility model relates to a kind of exposure factory building yellow fluorescent lamp.
Background technology
In board production, every layer of figure layer forms and be unable to do without light-sensitive material, the process that figure forms in three steps: whole plate covers light-sensitive material, exposure, development.Wherein exposure adopts ultraviolet ray to carry out.For fear of producing undesirable exposure, the illumination of exposure factory building is to adopt to throw light on away from the yellow fluorescent lamp of ultraviolet light, and the wavelength of yellow fluorescent lamp is generally more than 500nm, and 500nm ends below.Be applicable to Electronics Factory yellow light area, PCB factory building, the illuminations such as microelectronics factory, exposure room.
At present, the illumination of most exposure room adopts traditional cadmium yellow lamp illumination, and the major advantage of cadmium yellow lamp is: cost is low, and shortcoming is: severe toxicity, and frangible, light efficiency is low, and the life-span is short.
summary of the invention
The technical problems to be solved in the utility model is traditional cadmium yellow lamp illumination severe toxicity, and frangible, light efficiency is low, and the life-span is short.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of exposure factory building yellow fluorescent lamp, comprises white LED lamp assembly, drives constant-current source, blue light absorption cover; Drive Constant current input end to connect the civil power of peripheral hardware, output connects and is white LED lamp assembly power supply, and blue light absorption cover covers white LED lamp assembly.
Adopt the combination that white LED lamp assembly is luminous, blue light absorption cover filters, reach the effect of elimination blue light, reservation gold-tinted.And the shortcoming that does not have existing cadmium yellow lamp, light efficiency is high, nontoxic.
For ensureing lamp assembly job stability, described white LED lamp assembly comprises the LED lamp group of at least one group, and described LED lamp group comprises above, a parallel with one another LED lamp pearl, is series connection between LED lamp group.The advantage of this connected mode is: if there is a LED lamp pearl short circuit in a LED lamp group, whole lamp assembly also only has the lamp pearl of a LED lamp group not work, and all the other LED lamp pearls are working properly; If there is a lamp pearl open circuit, other lamp pearls in a LED lamp group are highlighted, and all the other LED lamp pearls are working properly.Under both of these case, for other connection schemes, whole lamp shadow is rung less, make good stability, the long service life of lamp.
As a kind of improvement project of the present utility model, the nominal colour temperature of described LED lamp pearl is 3000K.LED colour temperature is chosen in 3000K left and right, and its blue light content is lower, is convenient to the realization of gold-tinted.
The utility model has the advantages that: simple in structure, good stability, light efficiency is high, nontoxic, long service life.
Brief description of the drawings
Fig. 1 is the circuit diagram of lamp pearl mounting circuit of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model comprises white LED lamp assembly, drives constant-current source, blue light absorption cover; Drive Constant current input end to connect the civil power of peripheral hardware, output connects and is white LED lamp assembly power supply, and blue light absorption cover covers white LED lamp assembly.
For ensureing LED light source reliability, light source mainly contains the LED composition lamp bar of 96 0.5W, and by 4 and 24 string connected modes (first and rear string), the advantage of this connected mode is: if wherein there is a LED lamp pearl short circuit, only have 4 LED lamp pearls not work, all the other LED lamp pearls are working properly; If there is a lamp pearl open circuit, there are 3 lamp pearls highlighted, all the other LED lamp pearls are working properly.Under both of these case, for other schemes, ring less to whole lamp shadow.
