Description
Technical field
The utility model relates to a kind of direct-injection type free from glare equipment, particularly a kind of direct-injection type free from glare area source.
Background technology
LED is the abbreviation of English light emitting diode (light emitting diode); its basic structure is an electroluminescent semi-conducting material, places on the leaded shelf, uses epoxy sealing then all around; play the effect of protection internal core, so the anti-seismic performance of LED is good.
For general illumination, people more need the light source of white.The LED that emitted white light in 1998 succeeds in developing.This LED is packaged together GaN chip and yttrium-aluminium-garnet (YAG) to make.(λ p=465nm Wd=30nm), sends sodium yellow after the YAG fluorescent material that contains Ce3+ that high temperature sintering is made is subjected to this blue-light excited and penetrates peak value 550nm GaN (gallium nitride) chip blue light-emitting.The blue-ray LED substrate is installed in the bowl-type reflection cavity, covers to be mixed with the thin resin layer of YAG, about 200-500nm.Blue light that the LED substrate sends part is absorbed by fluorescent material, the yellow light mix that another part blue light and fluorescent material send, can obtain white light.Now, for the InGaN/YAG White LED,, can obtain the white light of all kinds of colour temperature 3500-10000K by chemical composition that changes YAG fluorescent material and the thickness of regulating phosphor powder layer.Thisly obtain the method for white light by blue-ray LED, simple structure, with low cost, technology maturity is high, therefore utilization is at most.
The characteristics of led light source:
1. voltage: LED uses low-tension supply, and supply voltage is between 6-24V, and is different and different according to product, so it is the power supply of a safety, is specially adapted to the public place.
2. usefulness: consumed energy reduces 80% with the incandescent lamp of light efficiency.
3. applicability: very little, each unit LEDs small pieces is squares of 3-5mm, thus can be prepared into the device of different shape, and be suitable for variable environment.
4. stability: 100,000 hours, light decay was initial 50%.
5. response time: the response time of its incandescent lamp is a Millisecond, and the response time of LED lamp is a nanosecond.
6. environmental pollution: no poisonous metal mercury.
7. color: changing electric current can variable color, and light emitting diode is adjusted the band structure and the band gap of material easily by chemical modification method, realizes that the green blue orange of reddish yellow is multicolor luminous.Be red LED during as little electric current,, can become orangely successively that yellow be green at last along with the increase of electric current.
8. the price comparison costliness of price: LED compares to incandescent lamp, and the price of several incandescent lamps just can be suitable with the price of a LED lamp, and common every group of signal lamp needs to be made of last 300～500 diodes.
9. drive: LED uses low-voltage DC to drive, and has the advantage that load is little, interference is weak, requires lower to environment for use.
10. the colour rendering height of colour rendering height: LED can not damage people's eyes.
Modern lighting apparatus requires to reduce the pollution level of light as far as possible, and promptly the key light of lighting apparatus must project desired direction, prevents that simultaneously light scattering from producing dazzle on other direction or on other direction.For example, its light that scatters to side and back of searchlight that is contained in ground should lack as far as possible, otherwise may make the pedestrian feel disagreeable.In the general lighting equipment of speculum fix in position, can only move whole lighting apparatus during the angle that regulate light beam and regulate its angle.So just change the slit with respect to the angle of object on every side, thereby also changed the place (from observer's angle) the when slit stops light beam.If the slit in the lighting apparatus of An Zhiing can not prevent effectively that again astigmatism from arriving observer's eyes, then will make the people dazzle the eyes again.
In the prior art, also have a kind of free from glare desk lamp (as shown in Figure 11) that adopts the refracting plate refraction, wherein, Reference numeral is represented respectively: 21, light source.22 LGPs, 23, light-emitting area.From Figure 11 we as can be seen, this desk lamp makes the LED lighting angle change 90 °, and makes the user can't see granular light source, but has the defective that the illumination loss is big, energy consumption is high.
In the prior art, do not have direct-injection type free from glare LED desk lamp.
