Abstract
The invention relates to the technical field of lighting devices, in particular to a healthy LED chip module capable of eliminating blue-light hazards. The healthy LED chip module comprises an LED luminous chip, a spotlight cover and a fluorescent layer. The LED luminous chip is covered with one end of the spotlight cover, and the fluorescent layer is plugged to the other end of the spotlight cover and is not in contact with the LED luminous chip. According to the healthy LED chip module, as the LED luminous chip is covered with the spotlight cover, leakage of light emitted by the LED luminous chip can be prevented, and light emitted by the LED luminous chip is gathered, totally penetrates through the fluorescent layer and is emitted outwards; in addition, as the fluorescent layer seals the whole light outgoing end of the spotlight cover and is not directly arranged on the surface of the LED luminous chip in a coating mode, it is achieved that all the light emitted by the LED luminous chip is gathered and filtered, and the aim of eliminating blue light is achieved accordingly.
Description
Technical field
The present invention relates to technical field of lighting fixtures, particularly relate to and a kind ofly eliminate the healthy LED chip module of blue light harm and apply its Zoom lamp.
Background technology
Under the background that Present Global energy starved worry raises once again, economize energy is the important problem that we will face future, at lighting field, the application of LED luminous product is just attract the sight of common people, LED is as a kind of novel green LED light source product, the necessarily trend of future development, 21st century is novel illumination LED light source epoch of representative by entering with LED.LED is called as green LED light source, has the features such as energy-saving and environmental protection, the life-span is long, volume is little, can be widely used in the fields such as various instruction, display, decoration, back of the body LED light source, general lighting and urban landscape.
Existing LED light source is generally adopt COBLED chip as light source.What COBLED chip sent is only mixed by not sharing the same light of a lot of different wave length, and the blue light that wherein adulterates is the harmful light that generation is the highest and the highest to human eye injury.The light source of existing COBLED lamp mainly contains two kinds: prior art one, and the light that LED chip sends directly shines out through translucent constructions such as lens, is not provided with any filtering structure.Prior art two, the light-emitting area of LED chip scribbles fluorescence coating, utilizes fluorescent material to carry out filter blue light by the principle of the gold-tinted of blue-light excited generation, and the light that COBLED chip sends shines out through other translucent constructions through fluorescence coating again.
Prior art one is not provided with any filtering structure, and the light that this LED light source sends is gone out with regard to direct irradiation without any process, and this illumination light is very easily impacted human eye health.
Although prior art two has set up fluorescence coating on the basis of prior art one, but, adopt COBLED as the Zoom lamp of light source, due to the technological problems of COBLED, yellow circle (the aperture of one deck yellow around center spot circle can be produced in the process of zoom, this is because the fluorescent material skewness of COBLED causes) or imaging (many square LED chip after COBLED imaging, can be seen, this is because fluorescent material is directly fitted on COBLED chip, mixed light space is not had to cause), these two kinds bad phenomenons all can reduce the light quality of light fixture greatly.Because fluorescence coating setting position is too near LED chip, and blue light has certain wavelength, when fluorescence coating is too near LED chip, blue light can utilize own wavelength to walk around this fluorescence coating and shine out, thus can not be filtered out completely by this fluorescence coating, this fluorescence coating is extremely limited to the filtration of harmful light, and this LED chip can not eliminate the blue light that COBLED chip is launched.
Summary of the invention
The object of the invention is to propose a kind of eliminate blue light harm, the healthy LED chip module of more Healthy Lighting can be realized and apply its LED Zoom lamp.
For reaching this object, the present invention by the following technical solutions:
