Or dead lamp.Even if can be by yellow fluorescence glass-encapsulated, but white light more than 5500K colour temperatures can only be produced, and fog lamp is needed
Want the gold-tinted that penetrability is extremely strong, it is desirable to which use requirement can just be reached by sending the gold-tinted of 1600K-3000K or so in colour temperature,
Therefore above-mentioned traditional mode can not smoothly solve the above problems.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of high temperature resistant nondiscolouring and can greatly extend light
Source service life and it colour temperature can be sent can reach the LED car fog lamp light sources and its processing method of 1600K-3000K or so gold-tinteds.
The utility model is realized using following technical proposals：
A kind of LED cars fog lamp, including car light housing, light source and drive circuit, the drive circuit and light source are arranged on car
In lamp housing, it is characterised in that：The light source includes aluminium nitride substrate, LED chip and light conversion medium, and the LED chip is led to
Cross and be fixed in parallel or series in upside-down mounting mode on aluminium nitride substrate；The smooth conversion medium is a kind of glass, the glass
Thickness is between 0.2-0.35mm, it is seen that light transmission rate is more than 50%, and the glass at least adds wavelength in manufacturing process
For the powder (Sialon ceramic powder) of 590-640nm one or more sialon systems；The glass passes through high temperature crystal-bonding adhesive
Chip surface is bonded at, and is surrounded chip with glass with a kind of white high temperature box dam glue around LED chip, after lighting
It is 1600K-3000K left that LED chips are sent into light that wavelength is 420-470nm by that can send colour temperature after the gamma transition
Right gold-tinted.
Meanwhile, described LED car fog lamp light source processing methods comprise the following steps：
Step one, the preparation of light conversion medium：The smooth conversion medium is a kind of glass, and the thickness of the glass is in 0.2-
Between 0.35mm, it is seen that light transmission rate is more than 50%, and the glass at least adds wavelength for 590- in manufacturing process
The powder of 640nm one or more sialon systems；
Step 2, die bond：One or plurality of LEDs chip are fixed on by parallel or series in upside-down mounting mode aluminum-nitride-based
On plate；
Step 3, the installation of light conversion medium：By the glass prepared in step one, chip is adhesive in by high temperature die bond
Surface, and surrounded chip with glass with a kind of white high temperature box dam glue around LED chip；
Step 4, after energization is lighted, light that wavelength is 420-470nm is sent by can after the gamma transition by LED chip
To send gold-tinted of the colour temperature as 1600K-3000K or so.
The utility model has advantages below：The utility model has innovatively used a kind of by doping kind or a variety of
The glass of the powder of sialon systems, is made by way of upside-down mounting and is applied to after light source in LED car Anti-fogging structures, is not only resistant to
High temperature nondiscolouring, and due to the covering of glass, what is produced in car body can not also invade light source with corrosive gas, greatly
Extend the life-span of light source.
