Abstract
The utility model discloses a blue ray-resistant LED light source and relates to the technical field of LED illumination. The blue ray-resistant LED light source comprises a heat transfer support. A plurality of LED chips are bounded on the heat transfer support. Two ends of the heat transfer support have LED electrodes which are electrically connected to the LED chips. The heat transfer support is also provided with annular enclosure glue, the annular enclosure glue is filled with fluorescent glue, the fluorescent glue covers the LED chips, and the surface of the fluorescent glue is provided with a blue-ray filter. The beneficial effects of the blue ray-resistant LED light source are that the blue-ray filter is arranged to effectively filter blue rays, the peak energy of the blue rays is reduced, harm on eyes caused by the high-energy blue rays can be prevented, and the LED light source is enabled to be a real safe, eye-protecting, healthy and environmental-friendly light source.
Description
[technical field]
The utility model relates to lighting technical field, and in particular, the utility model relates to a kind of anti-blue light LED light source.
[background technology]
Be called as the 4th generation light source LED, under the dual promotion of the capital of property and government subsidy, realized in recent years explosive growth.Yet the safety problem of LED has but caused part medical circle personage's uneasiness, there is expert to worry " LED blue light can cause damage to retina, even may cause infant blind ".
On Vehicles Collected from Market, a lot of LED light fixtures are that the fluorescent material that sends blue-light excited yellow by chip reconciles into white light, and the peak value of spectral energy is just in time in blue wave band, also because the light decay of fluorescent material is than very fast, use to have more blue lights after a period of time and overflow.
The long-term LED lamp that uses, easily allows people produce dizzy, uncomfortable sensation, even can cause the fine injury of eye, and the probability having a trouble in one's eyesight can be increased, and even causes biological clock disorderly, thereby reduces people's immunity.Tender and lovely children of eyes particularly, infant's crystalline lens is limpider, cannot filter blue light, and child has the nature of following spot, be subject to long-term a large amount of blue light illumination, may cause child's retina to occur phototoxic damage, serious even can cause amphiblestroid ceasma, to such an extent as to blind.
[utility model content]
The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, a kind of LED light source of anti-blue light is provided, and this anti-blue light LED light source can be removed or significantly reduce the blue light that LED light source sends, and effectively controls blue peak energy, make the LED light source safety that becomes, can not cause damage to human eye.
The technical solution of the utility model is achieved in that it comprises a heat transfer support, on described heat transfer support, be adhesive with plurality of LEDs chip, the two ends of heat transfer support also have the electrode that is electrically connected to LED chip, on described heat transfer support, be also provided with annular box dam glue, and this annular box dam glue inside is filled with the fluorescent glue covering on above-mentioned LED chip, and its improvements are: the surface of described fluorescent glue is provided with one deck blue light filter;
In above-mentioned structure, described blue light filter is formed by sheet glass, quartz plate, transparent PC, transparent PMMA or the transparent fat plating multi-layer transparent film of moulding.
In above-mentioned structure, on described heat transfer support, be adhesive with one or plurality of LEDs chip.
The beneficial effects of the utility model are: the utility model arranges one deck blue light filter by the surface at fluorescent glue, this blue light filter is by sheet glass, quartz plate, transparent PC, transparent PMMA or the transparent fat plating multi-layer transparent film of moulding form, by thicknesses of layers and index of refraction, the light of energy multiple reflections blue light wavelength, reduce the light transmittance of blue light wavelength, reach the object of filtering blue light, therefore, the light that LED chip sends is excited into after white light by fluorescent glue, the blue light filter arranging effectively filters blue light, reduce the peak energy of blue light, the injury that can avoid high-octane blue light to cause eyes, allow LED light source become real safety, eyeshield, the light source of health environment-friendly.
[accompanying drawing explanation]
Fig. 1 is generalized section of the present utility model;
Fig. 2 is vertical view of the present utility model.
[embodiment]
Below in conjunction with drawings and Examples, the utility model will be further described.
Shown in Fig. 1, Fig. 2, the utility model has disclosed a kind of anti-blue light LED light source, and this anti-blue light LED light source filters for the blue light that LED light source is emitted beam, the injury of avoiding high-octane blue light to cause eyes.In the present embodiment, anti-blue light LED light source comprises a heat transfer support 10, is adhesive with plurality of LEDs chip 101 on heat transfer support 10, and the quantity of LED chip 101 can arrange as required, is adhesive with four LEDs chips 101 in the present embodiment on the support 10 that conducts heat; The two ends of heat transfer support 10 have the LED electrode 102 being electrically connected on LED chip 101, by this LED electrode 102, are connected on external drive power supply, luminous by driving power driving LED chip 101.
On heat transfer support 10, be also provided with annular box dam glue 20, and these annular box dam glue 20 inside are filled with the fluorescent glue 30 covering on above-mentioned LED chip 101, therefore, the light that LED chip 101 sends, can be by the white light that is excited into of fluorescent glue 30, above-mentioned box dam glue 20 is provided with one deck blue light filter 40 with the surface of fluorescent glue 30, and this blue light filter 40 is by sheet glass, quartz plate, transparent PC, transparent PMMA or the transparent fat plating multi-layer transparent film of moulding form, by thicknesses of layers and index of refraction, the light of energy multiple reflections blue light wavelength, reduce the light transmittance of blue light wavelength, reach the object of filtering blue light, therefore, the light that LED chip 101 sends is excited into after white light by fluorescent glue 30, the 40 pairs of blue lights of blue light filter that arrange effectively filter, reduce the peak energy of blue light, the injury that can avoid high-octane blue light to cause eyes, allow LED light source become real safety, eyeshield, the light source of health environment-friendly.
Described above is only preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to restriction of the present utility model.In technological thought category of the present utility model, can there is various distortion and modification, the retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, all belong to the scope that the utility model is protected.
