Description

A kind of YAG crystal light-sources

Technical field

The utility model is related to technical field of LED illumination more particularly to a kind of YAG crystal light-sources.

Background technology

Traditional incandescent lamp is using filament light-emitting, and the service life of incandescent lamp, the burning point time will not nor very stable More than 500 hours, and power consumption was big.Increasingly deficient with the energy, man invented has that power consumption is small, and calorific value is small, makes The LED light of the advantages that with long lifespan.

And with the development of LED technology, LED point light source is widely used in lighting area, since it has energy saving, ring Guarantor, long-life etc. need advantage, it is considered to be and energy-saving best approach, LED point light source are known as 21 century green light source, So while LED point light source has the advantages that many, and with wide development trend, thus it is widely applied, especially It is to be applied in present Home Fashion ＆ Design Shanghai, municipal works, architectural lighting etc. field, but existing LED point light source can only be done It is acted on to general lighting, can not accomplish the effect of uniformly light-emitting, while existing LED light source transfer efficiency is low.

Utility model content

The purpose of this utility model is to provide a kind of YAG crystal light-sources, solves LED light source conversion of the prior art Efficiency is low, the technical issues of can not accomplishing uniformly light-emitting.

A kind of YAG crystal light-sources, including YAG crystal, reflecting surface, point light source and housing, the enclosure interior is provided with peace Tankage, the mounting groove is transparent mounting groove, and mounting groove is internally provided with the point light source, and the YAG crystal is located at described Between reflecting surface and point light source.

Based on the above technical solution, the utility model can also do following improvement：

Further, the point light source is laser light source.

Further, the point light source is one or two.

Further, for the YAG crystal for the YAG crystal after high temperature sintering, the advantageous effect using this step is that high temperature is burnt YAG crystal after knot can realize uniformly light-emitting.

Further, the reflecting surface is curved reflecting surface, is coordinated using the advantageous effect and YAG crystal of this step, is formed The light source of uniformly light-emitting.

The beneficial effects of the utility model：

The utility model is a kind of YAG crystal light-sources, by the use of laser light source as point light source, by YAG crystal reflections with Refraction can form the light source of uniformly light-emitting, and light source conversion ratio is high, will not be by influence of moisture；The utility model structure Simply, it shines uniform, and color rendering is high.

Specific embodiment

The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described Embodiment is the utility model part of the embodiment, instead of all the embodiments.Based on the embodiment in the utility model, sheet Field those of ordinary skill all other embodiments obtained without making creative work, belong to this practicality Novel protected range.

Embodiment 1

As shown in Figure 1, a kind of YAG crystal light-sources provided by the utility model, including YAG crystal 1, reflecting surface 2, point light Source 3 and housing 4, the housing 4 are internally provided with mounting groove 5, and the mounting groove 5 is transparent mounting groove, and is set inside mounting groove 5 Be equipped with the point light source 3, the reflecting surface 2 is arranged on the inner wall of housing 4, the YAG crystal 1 be located at the reflecting surface 2 with Between point light source 3, point light source can be reflected and reflected by YAG crystal, form the point light source of uniformly light-emitting.

Wherein, the point light source 3 is laser light source, and the point light source 3 is one or two.

Wherein, the YAG crystal 1 is the YAG crystal 1 after high temperature sintering, and the YAG crystal after high temperature sintering can be realized Even to shine, YAG crystal can be ellipse or spherical.

Wherein, the reflecting surface 2 is curved reflecting surface, coordinates with YAG crystal 1, forms the light source of uniformly light-emitting.

Finally it should be noted that：The above various embodiments is only to illustrate the technical solution of the utility model rather than it is limited System；Although the utility model is described in detail with reference to foregoing embodiments, those of ordinary skill in the art should Understand：It can still modify to the technical solution recorded in foregoing embodiments either to which part or whole Technical characteristic carries out equivalent replacement；And these modifications or replacement, this practicality that it does not separate the essence of the corresponding technical solution are new The range of each embodiment technical solution of type.
