Abstract
An LED (light emitting diode) illuminating lamp comprises a bulb shell, an LED light source and a reversible photochromic layer, wherein the LED light source is arranged in the bulb shell; and the reversible photochromic layer is arranged on the bulb shell and can be stimulated by light emitted from the LED light source. Because the reversible photochromic layer which can be stimulated by the light emitted from the LED light source is arranged on the bulb shell of the LED illuminating lamp, when the LED illuminating lamp is turned on, the light, which does not facilitate color development, in a spectrum can be filtered out after the color of the reversible photochromic layer is changed, and the color development index of the LED illuminating lamp is improved. The LED illuminating lamp has the advantage of high color development index.
Description
Technical field
The present invention relates to a kind of LED light device, particularly a kind of LED illumination lamp.
Background technology
LED due to the advantages such as energy-conserving and environment-protective more and more welcome, have that luminous efficiency is high, power saving and a life-span long advantage.A large amount of gold-tinteds is included in the light that current LED sends due to LED light source, cause the colour rendering index of whole lamp on the low side, the such as day for announcing is on June 25th, 2014, the patent No. be 201310084415.7 Chinese invention patent disclose a kind of Large-angle emission LED lamp, comprise body, bulb housing and multiple light source board, this bulb housing is located at the top of this body, each light source board includes substrate and is arranged on the LED light source on this substrate lateral surface, the base of described substrate is fixedly installed on the top of this body, lateral surface on described substrate and the top of this body are arranged in obtuse angle, described substrate is angularly arranged around the axis of this body.But this LED, owing to not being unfavorable for that the light developed the color carries out filtering and just shone directly into space outerpace in emitting beam, causes the colour rendering index of whole lamp on the low side.
Summary of the invention
In view of this, the LED illumination lamp providing a kind of colour rendering index high is necessary.
A kind of LED illumination lamp, comprise bulb housing, LED light source and ability of reverse photochromism layer, this LED light source is arranged in this bulb housing, and this ability of reverse photochromism layer is arranged on this bulb housing, and the light that this LED light source sends can excite this ability of reverse photochromism layer variable color.
Compared with prior art, this LED illumination lamp is provided with and can be emitted beam the ability of reverse photochromism layer excited by LED light source on bulb housing, when this LED illumination lamp is lighted, the light being unfavorable for developing the color can be filtered out in spectrum after this ability of reverse photochromism layer variable color, which improves the colour rendering index of this LED illumination lamp, make this LED illumination lamp have the high advantage of colour rendering index.
Accompanying drawing explanation
Fig. 1 is the generalized section of LED illumination lamp of the present invention;
Description of reference numerals:
10 bulb housing 20 ability of reverse photochromism layer 30LED light sources
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail.
Please refer to Fig. 1, this LED illumination lamp 100 comprises bulb housing 10, LED light source 30 and ability of reverse photochromism layer 20, and this LED light source 30 is arranged in this bulb housing 10, and this ability of reverse photochromism layer 20 is arranged on this bulb housing 10.
Please refer to Fig. 1, this bulb housing 10 was hemisphere cell-shell, and this bulb housing is made up of glass.
Please refer to Fig. 1, this ability of reverse photochromism layer 20 is for being coated in the ability of reverse photochromism coating of this bulb housing 10 inner surface, this ability of reverse photochromism layer 20 is without the transparent or semitransparent state of color under the irradiation not being subject to ultraviolet light or infrared light, variable color after the irradiation being subject to ultraviolet light or infrared light, after ultraviolet light or infrared light disappear, this ability of reverse photochromism layer 20 changes into again without color state.Preferably, the variable color when being subject to UV-irradiation of this ability of reverse photochromism layer 20 is purple.
Please refer to Fig. 1, this LED light source 30 comprises the fluorescent material (not shown) of LED chip (not shown) and this LED chip coated, includes ultraviolet light or infrared light in the light that this LED chip sends.Preferably, ultraviolet light is included in the light that the LED chip of this LED light source 30 sends.This fluorescent material is RGB composite phosphor, and the light that this LED chip sends forms the white light mixed by multiple color light after this RGB fluorescent material.Wherein the light that sends of this LED chip injects to this ability of reverse photochromism layer 20 still having part ultraviolet light after this RGB fluorescent material, this ability of reverse photochromism layer 20 becomes purple after being subject to the ultraviolet excitation that this LED chip sends, and it is the gold-tinted of 560nm ~ 590nm that the ability of reverse photochromism layer 20 of this purple can partially absorb the wave-length coverage that this RGB composite phosphor sends.Because the spectral component near 580nm wavelength in spectrum has adverse effect to Color development, if after the light irradiating object including this spectral component, can cause some cross-color of this object, therefore after eliminating close 580nm yellow light area light, colour rendering index will increase substantially.
In sum, this LED illumination lamp 100 is provided with and can be emitted beam the ability of reverse photochromism layer 20 excited by LED light source 30 on bulb housing 10, when this LED illumination lamp 100 is lighted, the light being unfavorable for developing the color is filtered in spectrum after this ability of reverse photochromism layer 20 variable color, which improves the colour rendering index of this LED illumination lamp 100, make this LED illumination lamp 100 be provided with the high advantage of colour rendering index.Because this LED light source 30 can send ultraviolet light, and this ability of reverse photochromism layer 20 can be purple by ultraviolet excitation variable color, this purple ability of reverse photochromism layer 20 can the gold-tinted of filtering 560nm ~ 590nm, and the colour rendering index of this LED illumination lamp 100 is increased substantially.Because this ability of reverse photochromism layer 20 is colourless when this LED illumination lamp 100 is not lighted, therefore the outward appearance of whole lamp can not be affected.Because this ability of reverse photochromism layer 20 is coated in the ability of reverse photochromism coating of this bulb housing 10 inner surface for one deck, do not need to arrange filter part in addition to improve aobvious finger, therefore make this LED illumination lamp 100 be provided with the simple advantage of structure.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement, improvement etc., all should be included in the scope of protection of the invention.
