Abstract
The utility model discloses a blue-light LED lampshade and a blue-light LED utilizing the same of a neonatal jaundice therapy apparatus. The lampshade is conical, a lampshade cap is arranged at the top of the lampshade, and the surface of the lampshade cap has a concave-and-convex alternative arc structure. Correspondingly, the blue-light LED lamp comprises a blue-light LED lamp holder, wherein the blue-light LED lamp holder is arranged in the blue-light LED lampshade of the neonatal jaundice therapy apparatus. The blue-light LED lampshade has the advantages that power consumption of the blue-light LED lamp is lowered on the premise of keeping the same light intensity since the surface of the lampshade cap has the concave-and-convex alternative arc structure. The blue-light LED lamp utilizing the blue-light LED lampshade has the advantages that the blue-light LED lamp with the same power has better lighting effect, the number of light emitting diodes is reduced greatly in use, and accordingly waste of energy and the like is reduced.
Description
It is that on 07 08th, 2011, application number are that present patent application requires the applying date: 201120252249.3, name is called: the priority of the blue LED lamp lampshade of neonatal jaundice therapeutic instrument and the blue LED lamp of neonatal jaundice therapeutic instrument.
Technical field
This utility model relates to photo-therapeutic instrument device field.
Background technology
LED=Light Emitting Diode, light emitting diode is a kind of solid-state semiconductor device that can electric energy be converted into visible light, it can directly be converted into light to electricity.Large-power light-emitting diodes refers generally to luminous power 0.5W, 1W, 3W, 5W or higher.The light intensity of large-power light-emitting diodes and lumen are bigger than low power LED, but same heat radiation is also very big, and now high-power all is single application, adds very big fin.
Newborn with unconjugated mass formed by blood stasis (jaundice) is the neonate common frdquently encountered disease, is prone to cause hearing impairment, and severe patient can bilirubin encephalopathy take place and influence life quality, is the common problem that neonate faces.Visible jaundice all can take place in about 60% infant during first week of birth.About 8% neonate need be treated the jaundice that hyperbilirubinemia causes.Phototherapy had become the treatment standard of the jaundice relevant with neonate life in past 40 years.
Bilirubin ability absorbing light, under the effect of light and oxygen, fat-soluble bilirubin is oxidized into a kind of water miscible product (light-oxidation bilirubin, promptly two pyrroles), can excrete from bile or urine, thereby reduce serum unconjugated bilirubin concentration.Bilirubinic absorption band is 400～500 millimicrons, and is especially the strongest at 420～440 mm-wave long time photodecompositions, and blue-fluorescence wavelength main peak is between 425～475 millimicrons, so the blue-fluorescence lamp that adopts is treated more.
Abroad, some medical research exploitation units have had some to adopt the neonatal jaundice therapeutic instrument of blue-ray LED as the treatment light source.NeoBLUELED Phototherapeutic instrument such as the production of U.S. natus company.Through blue LED, this Phototherapeutic instrument provides extremely effectively bilirubin degradation effect.With respect to traditional phototherapy apparatus, the amount of radiation of NeoBLUE ultraviolet light is extremely low, has reduced the injury to infant skin; The amount of radiation of infrared light is also few, has reduced the danger of loss of moist in the infants.The blue light neonate Phototherapeutic instrument of General Electric Co. Limited's medical board development has three blue-light treatment LED lamps, can carry out omnibearing treatment to neonate, can smash the bilirubin pigment, is free from side effects.To the curative effect of LED phototherapy, also carried out the single led effect of relevant clinical observation: H.J.Vreman both at home and abroad, and made the Phototherapeutic instrument model that contains 300 LED through the contrast different wave length.With the comparative study of traditional instrument, can carry out through photodegradative measurement to the Albumin (human blood serum)..Contrasted blue light, blue green light, green glow, white light LEDs, blue light produces effect most.The research worker of Israel has designed uses the novel Phototherapeutic instrument of GaNLED as the narrow-band blue light light source, and light intensity is roughly consistent with traditional Phototherapeutic instrument, even stronger.Through the colony that comprises 69 jaundice infants is opened random research, obtain continuing the relation data of phototherapy and serum bilirubin level decline.The result of led light source is-3116mmolP (LP h), conventional light source be-2119mmolP (LP h) that the more remarkable treatment effect of led light source is described.Domestic medical and nursing work person's observation has also confirmed the curative effect of LED blue light Phototherapeutic instrument.
On the one hand, reach 10000 hours the service life of blue LED lamp, significantly reduced the spending and the consumption that more change the bulb; On the other hand, blue-ray LED is the interior effective energy of emitted in ultraviolet line ranges not, can reduce the potential risk of skin injury; LED is a cold light source, and heat production is few, the few side effects that brings.
Similar products all adopt the intensive compact arrangement of a large amount of light emitting diodes to reach rational jaundice treatment technology index now.For example be: 201020228852.3 at application number; Name is called: disclose the yellow cellulitis therapeutic instrument of a kind of LED neonate in the utility model of LED neonatal jaundice therapeutic instrument; LED blue light lamp plate, timing controller, LED driving power are housed in the shell by bracket supports; The LED blue-ray light of one group of vertical, horizontally-arranged row, uniform distribution are housed on the said LED blue light lamp plate, outwards placing, timing controller and driving power can timing controlled and driving LED blue light lamp plate work.In this product, light emitting diode is directly installed on the panel, and the light utilization rate is not high, thereby same brightness, and use amount is bigger, thereby the fault rate of product is also high; Inevitable, the product power consumption is high, and energy waste is many.Therefore, how to reduce LED blue-ray light use amount, improve the illumination service efficiency of LED blue-ray light, become a kind of inevitable requirement.
