Background technology

The LED semiconductor lighting is as lighting engineering of new generation, have that photoelectric conversion rate is high, light source direction is easily controlled, the period and mode is easily controlled, color rendering properties of light source is high, have five incomparable large power savings advantages of higher other existing lighting engineering such as power factor under the appropriate design of throwing light on, be subject to the favor of global investor and vigorously supporting of national governments.The luminous efficiency of current LED illuminating lamp can surpass 70LM/W mostly, has more power savings advantages than traditional electricity-saving lamp.The green light LED luminous efficiency can be up to 683LM/W in theory; The theoretical efficiency of white light LEDs also can reach 182.45LM/W, so the space that the LED illumination efficiency promotes is huge.

In existing high-power LED illumination product design, high-powered LED lamp particularly, reason owing to heat radiation, during a high-powered LED lamp of assembly, adopt LED optical mode group, driving power and the design of light fixture three in one, be that the parts such as LED optical mode group, driving power and light fixture must form a complete production network, formed the situation of so-called " LED has lamp without bulb ".This has brought a series of fatal problems such as manufacturing cost is high, use inconvenience, maintenance difficult for the LED illuminating product.At first make the upper unified standard production that can't realize the whole nation and even the whole world, cause product specification many, batch less, price is high; Next is that each product is of all kinds, not general mutually, more can not exchange; The 3rd need to take off maintenance with whole assemblies such as LED optical mode group, driving power, light fixtures when being product bug, and maintenance is inconvenience very, is very easy to form the defectives such as fault extension and maintenance delay, maintenance cost is high.These defectives have greatly restricted promoting the use of of LED illumination, are the hard defects during the LED illuminating product is promoted.

The utility model content

The purpose of this utility model is, a kind of integral LED bulb of liquid fluorescence is provided.The bulb that the utility model method consists of can work independently, realized that LED bulb, light fixture and illumination control product is independent separately on producing and on using, made the LED illuminating product reduce significantly production link, improve production lot, be conducive to the industrialization of LED energy-saving illumination product.

The technical solution of the utility model: the integral LED bulb of liquid fluorescence, be characterized in: comprise flange-cooled heat conduction support (can adopt the nonmetallic heat conductive material sinter moldings such as aluminium oxide, aluminium nitride, boron nitride), chimeric on the heat conduction support have silver to starch printed circuit, is welded with led chip or also is welded with the driving chip on the silver slurry printed circuit; Described heat conduction support is provided with caulking groove, embeds on the caulking groove to be fixed with the bulb inner cover, and the bulb inner cover covers led chip and drives chip, and the bulb inner cover accommodates the transparent insulation conductive fluid, in the described transparent insulation conductive fluid fluorescent material can be set as required; Described led chip is packaging silicon rubber not, and described led chip is immersed in the transparent insulation conductive fluid; The edge of described heat conduction support is the mounting flange structure.

In the integral LED bulb of aforesaid liquid fluorescence, described bulb inner cover is the spill inner cover, and the spill inner cover is the elasticity inner cover of slim concave inward structure.In this structure when the LED heating power, the transparent insulation conductive fluid flows because being heated and has taken away the heating of chip, heat is exchanged with radiator on larger area, avoided the traditional scheme led chip to reach the local high heat of fluorescent material on every side, effectively reduced the generation of LED light decay, and when transparent insulation conductive fluid expanded by heating, the spill inner cover of indent is outwards outstanding, the volume of enlarging volume acceptable solution volume expansion avoids expansion of liquids to make the inner cover seal failure.

In the integral LED bulb of aforesaid liquid fluorescence, on the described heat conduction support caulking groove is set, outer bulb envelope directly embeds caulking groove by bonding.

In the integral LED bulb of aforesaid liquid fluorescence, on the described heat conduction support caulking groove is set, caulking groove is embedded in bonding and is provided with the lens snap ring, and card has lens on the lens snap ring.

In the integral LED bulb of aforesaid liquid fluorescence, connect and the fixed band Waterproof connector of cable by cable fixing head on the described heat conduction support.

Compared with prior art, the utility model goes out flange-cooled heat conduction support by nonmetallic heat conductive material direct sintering, and directly LED silver slurry printed circuit is entrenched in the heat conduction support, make the simpler compactness of LED bulb structure of formation, and the heat radiation of LED is faster.Add the setting of heat conduction support upper embedded groove, be convenient to the installation of lampshade, water resistance is good.And but the mounting structure direct sintering of bulb is on the heat conduction support.Utilize the integral LED bulb establishment light fixture of liquid fluorescence of the present utility model simple, flexible and changeable, allow like this bulb, light fixture and the illumination control Realization of Product of LED lamp independent separately on producing and on using, make the LED illuminating product reduce significantly production link, improve production lot, be conducive to the industrialization of LED energy-saving illumination product.
