Abstract
The utility model discloses an LED light source having high-quality illuminating light. The LED light source comprises an LED (1) and an LED electrode pin (2) leaded out by the LED (1). A spherical transparent body (3) is arranged outside the LED (1). A distance from an excircle of the spherical transparent body (3) to the center of the LED (1) is from 2.54 to 12.7 mm. An inner surface of the spherical transparent body (3) is coated with LED fluorescent powder. The LED electrode pin (2) is leaded from the spherical transparent body (3). According to the LED light source of the utility model, direct coating of fluorescent powder on a surface of the LED (1) is avoided; and the adoption of the spherical transparent body (3) can expand a light emitting area of the light source. Therefore, the outputted light can become downy, and glare produced by the point light source can be reduced.
Description
Technical field
The utility model relates to a kind of led light source, particularly a kind of led light source with high-quality illuminating ray.
Background technology
LED is the abbreviation of English word Light Emitting Diode, and promptly light-emitting diode is a kind of solid-state semiconductor device that can electric energy be converted into visible light, and it can directly be converted into light to electricity.
Led light source has following characteristics:
One, volume is little
Led light source is a kind of novel semiconductor light-emitting, is formed in epoxy resin by a very little semiconductor wafer package, can realize miniaturization.
Two, power consumption is low
The LED photoelectric conversion efficiency is high, under the situation of equal illumination than conventional light source energy-conservation nearly 80%.
Three, long service life
LED is the solid cold light source, does not exist filament light-emitting to be prone to the FAQs of glow discharge spot lamps such as burning, gas leakage, under suitable current and voltage, can reach 60,000 to 100,000 hours useful life, and is longer more than 10 times than the life-span of conventional light source.
Four, safety
LED can use low-voltage DC driven luminescence technology, and is safer than traditional glow discharge spot lamp.
Five, environmental protection
The not mercurous heavy metal material that waits does not have environmental pollution in the LED material in the use, can recycling behind the end-of-life yet.
Six, dazzle
Led light source is that light is very concentrated, is easy to generate dazzling dazzle by the direct luminous point-source of light of led chip, and light is not soft.
The characteristics of LED have determined it to use widely, and the research staff also is devoted to improve the various aspects of performance of LED, for example the illuminating ray quality.But, in practical application, directly applying the point-source of light of fluorescent material formation on LED surface, light is very concentrated, and is dazzling and a large amount of dazzles are arranged, and lighting quality is very poor.If at the external lampshade of LED, on lampshade, apply fluorescent material, then effect is very undesirable.LED user hope enjoy LED energy-conservation with high reliability in, can have soft high-quality illuminating ray.
The utility model content
The utility model technical scheme to be solved provides a kind of led light source with high-quality illuminating ray, and the illuminating ray of this led light source is softer.
In order to solve above-mentioned technical problem; The technical scheme of the utility model is: a kind of led light source; Comprise the LED electrode pin that LED and LED draw, said LED is outside equipped with the spherical transparent body, and the distance at the cylindrical of the said spherical transparent body and LED center is 2.54-12.7mm; The inner surface of the said spherical transparent body is coated with LED fluorescent material, and said LED electrode pin is drawn from the spherical transparent body.
Said LED electrode pin is needle-like or sheet.
LED is luminous after energising, is radiated at the inboard LED phosphor surface that applies of light shell outer cover, and excitated fluorescent powder is luminous, forms spherical led light source.
The led light source of the utility model is avoided directly applying fluorescent material on the LED surface, utilizes the spherical transparent body to enlarge the light-emitting area of light source, thereby makes output light become soft, has reduced the dazzle that point-source of light produces.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Accompanying drawing is the structural representation of the utility model.
Embodiment
Shown in accompanying drawing, the led light source of the utility model comprises the LED electrode pin 2 that LED1 and LED1 draw, and LED electrode pin 2 can be needle-like or sheet.
The key point of the utility model is, is outside equipped with the spherical transparent body 3 at said LED1, and this sphere transparent body 3 can be glass material, or processes for transparent macromolecule organic material, and it the most important thing is that light transmittance will get well.The inner surface of the said spherical transparent body 3 is coated with LED fluorescent material, and said then LED electrode pin 2 is drawn from the spherical transparent body 3.The spherical transparent body 3 has also enlarged the light-emitting area of light source.
Be the dazzle avoid point-source of light to produce, and avoid the cylindrical of the said spherical transparent body 3 excessive, absorb external energy minimizing with the distance on LED1 surface, can not be luminous efficiently, the distance at the cylindrical of the said spherical transparent body and LED center is 2.54-12.7mm.This distance is second key point of the utility model, and output light becomes soft on this distance, has reduced the dazzle that point-source of light produces.
The foregoing description limits the utility model never in any form, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in the protection range of the utility model.
Claims (2)
1. led light source; Comprise the LED electrode pin (2) that LED (1) and LED (1) draw; It is characterized in that: said LED (1) is outside equipped with the spherical transparent body (3); The distance at the cylindrical of the said spherical transparent body (3) and LED (1) center is 2.54-12.7mm, and the inner surface of the said spherical transparent body (3) is coated with LED fluorescent material, and said LED electrode pin (2) is drawn from the spherical transparent body (3).
2. led light source according to claim 1 is characterized in that: said LED electrode pin (2) is needle-like or sheet.
