Abstract
The invention discloses an LED light source with high-quality illumination light. The LED light source includes an LED (1) and an LED electrode pin (2) which is lead out by the LED (1). A spherical transparent body (3) is arranged at an outside of the LED (1); an excircle of the spherical transparent body (3) is 2.54 to 12.7mm away from a center of the LED (1); an interior surface of the spherical transparent body (3) is coated with LED phosphor; and the LED electrode pin (2) is lead out from the spherical transparent body (3). The LED light source of the invention prevents the phosphor from being coated directly on the LED (1) surface, and uses the spherical transparent body (3) to enlarge the light source luminous area, so that the output light is soft and the glare generated by the spot light source is minimized.
Description
Technical field
The present invention relates to a kind of led light source, particularly a kind of led light source with high-quality illuminating ray.
Background technology
The abbreviation of LED English word Light Emitting Diode, i.e. light-emitting diode, be a kind of can be the solid-state semiconductor device of visible light with electric energy conversion, 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, in the situation that equal illumination is than conventional light source energy-conservation nearly 80%.
Three, long service life
LED is the solid cold light source, does not have the FAQs of the glow discharge spot lamps such as filament light-emitting easily burns, gas leakage, under suitable electric 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 direct-current to drive 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 procedure, can recycling behind the end-of-life yet.
Six, dazzle
Led light source is that light is very concentrated, easily produces dazzling dazzle by the direct luminous point-source of light of led chip, and light is not soft.
The characteristics of LED have determined that it uses 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 actual applications, 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, apply fluorescent material at lampshade, then effect is very undesirable.LED user wishes can have soft high-quality illuminating ray in and the high reliability energy-conservation at enjoyment LED.
Summary of the invention
Technical scheme to be solved by this invention 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, technical scheme of the present invention is: a kind of led light source, comprise the LED electrode pin that LED and LED draw, described LED is outside equipped with the spherical transparent body, the distance at the cylindrical of the described spherical transparent body and LED center is 2.54-12.7mm, the inner surface of the described spherical transparent body is coated with LED fluorescent material, and described LED electrode pin is drawn from the spherical transparent body.
Described 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.
Led light source of the present invention 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
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Accompanying drawing is structural representation of the present invention.
Embodiment
As shown in drawings, led light source of the present invention comprises the LED electrode pin 2 that LED1 and LED1 draw, and LED electrode pin 2 can be needle-like or sheet.
Key point of the present invention is, is outside equipped with the spherical transparent body 3 at described LED1, and this sphere transparent body 3 can be glass material, or makes for transparent macromolecule organic material, and it the most important thing is that light transmittance will get well.The inner surface of the described spherical transparent body 3 is coated with LED fluorescent material, and then described 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 distance on the cylindrical of the described spherical transparent body 3 and LED1 surface excessive, absorb external energy and reduce, can not be luminous efficiently, the distance at the cylindrical of the described spherical transparent body and LED center is 2.54-12.7mm.This distance is second key point of the present invention, becomes soft at this distance output light, has reduced the dazzle that point-source of light produces.
Above-described embodiment does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
Claims (2)
1. led light source, comprise the LED electrode pin (2) that LED (1) and LED (1) draw, it is characterized in that: described LED (1) is outside equipped with the spherical transparent body (3), the distance at the cylindrical of the described spherical transparent body (3) and LED (1) center is 2.54-12.7mm, the inner surface of the described spherical transparent body (3) is coated with LED fluorescent material, and described LED electrode pin (2) is drawn from the spherical transparent body (3).
2. led light source according to claim 1 is characterized in that: described LED electrode pin (2) is needle-like or sheet.
