Description
Technical field
The present invention relates to LED technology fields, specifically for a kind of closed LED light with low light attenuation.
Background technique
From coming out first blue-ray LED in 1993, LED is applied to illumination and is just really become a reality.The LED of early stage
It mainly based on direct insertion, due to the limitation of structure, is packaged using epoxy resin, thus can not effectively break through heat dissipation and ask
Topic, to reach reduction light decay, improve service life.The appearance of TOPLED (surface PLCC pouring type light emitting diode) solves this
A technical problem, it is freer to the selection of packaging plastic since its size is small, by selecting the macromolecule organic silicon (to be commonly called as in industry
Silica gel) replace traditional epoxy resin as the external sealant of white light for illumination LED, solve the problems, such as that light decay is too fast substantially.
However the simultaneous moisture-inhibiting oxygen flow characteristic of silica gel, on encapsulation LED reliability produce certain influence, for example when
When the white light LEDs of silica gel technique touch sulphur-containing substance, element sulphur easily penetrates into cradling function area, with bracket silver-platedization
Learn reaction.Therefore, at present all mainstreams in this field theory all think LED light light decay be as vulcanization and caused by, thus
In order to achieve the purpose that anti-sulphur, it is all made of no sulfur materials on material and is manufactured.But it is puzzling, even if using nothing
After sulfur materials, the problem of light decay, is still had, those skilled in the art current for this phenomenon there are a great mistaken ideas,
Think that this phenomenon is as caused by still having part element sulphur to remain in lamp.Therefore, industry can be for element sulphur screening
Standard improves layer by layer, however but still without solving the problems, such as light decay very well.
Summary of the invention
Goal of the invention of the invention is: a kind of closed LED light with low light attenuation is provided, it is internal to use carbon-free analysis
Material is made to effectively reduce the light decay rate of LED light out.
The present invention is achieved through the following technical solutions: a kind of closed LED light with low light attenuation, including sealing lamp housing,
LED light source inside sealing lamp housing and driving power are set, it is characterised in that: each components inside the sealing lamp housing
It is made of carbon-free precipitation material, the operating temperature inside closed LED light is greater than 100 degrees Celsius.
For better implementation this programme, following prioritization scheme is also provided:
Further, the sealing lamp housing includes lamp cap, radiator and light transmitting shell, and driving power is arranged in radiator
Inside, driving power is equipped with inductance, and the outside of inductance is equipped with the inductive rack for fixed inductance, the lamp cap, driving
It is electrically connected between power supply, LED light source.
Further, the inductive rack is made of ceramics, glass or plastics.
Obviously, other can apply the non-carbon material in LED light to be also regarded as within protection scope of the present invention.
Further, the plastics are PBT plastic.
Than before for technology, the invention has the benefit that
Using the light decay of LED light is significantly reduced, substantially increase
The service life of LED light overcomes in the industry for the technology prejudice of LED light light decay factor.
Detailed description of the invention
Fig. 1 is the LED light schematic cross-section in the present invention.
Label declaration: 1- driving power, 10- inductance, 11- inductive rack, 2- lamp cap, 3- radiator, 4-LED light source, 6-
Light transmitting shell.
Specific embodiment
Illustrate to elaborate to the present invention with reference to the accompanying drawing:
The present invention includes sealing lamp housing, the LED light source 4 being arranged in inside sealing lamp housing and driving power 1, and feature exists
In: each components inside the sealing lamp housing are made of carbon-free precipitation material, the operating temperature inside closed LED light
Greater than 100 degrees Celsius.
Further, the sealing lamp housing includes lamp cap 2, radiator 3 and light transmitting shell 6, and the setting of driving power 1 is dissipating
The inside of hot device 3, driving power 1 are equipped with inductance 10, and the outside of inductance 10 is equipped with the inductive rack 11 for fixed inductance 10,
The lamp cap 2, driving power 1 are electrically connected between LED light source 4.
Further, the carbon-free precipitation material is plastics, and the plastics are PBT plastic.
The principle is as follows:
It finding by applicant by a large amount of comparative experiments, the reason of influence LED light light decay is diversified in fact,
Not only only vulcanize one kind, the light decay scene that the carbonization of actually inductive rack also results in LED light generates.
In this regard, inductive rack made by the material under high temperature without carbon emissions and existing common electricity is respectively adopted in applicant
The LED light of sensing rack carries out light decay experiment (as shown in the table), the result is that the light decay rate of the latter has dropped 4% or more than the former,
Significant effect is produced, the conjecture of applicant has also been confirmed, where at present this also explains the sulphur standard anti-in the industry for mentions again and again
In the case where rising, the still serious problem of the light decay of LED light overcomes technology prejudice in the industry, produces significant effect.

Although the present invention is illustrated and illustrated to the present invention using specific embodiment and its alternative, but it should reason
Solution, can be implemented without departing from the variations and modifications in scope of the invention.It is therefore understood that in addition to by with
Outside the limitation of attached claim and its condition of equivalent, the present invention is not limited by in all senses.
