The LED lamp is characterized in that a ceramic shell is adopted as the shell; an LED lighting module which takes aluminum as a lining plate is adopted as the LED panel, and used for providing lighting beams; and the drive power source is used for providing energies for the LED panel. In the LED lamp, structural optimization is implemented on a traditional lamp; a plurality of insulation materials are saved; and the product size is reduced.

Description

A kind of LED light fixture
Technical field
The utility model belongs to lighting technical field, is specifically related to a kind of LED light fixture.
Background technology
The energy consumption of lighting field accounts for 20% of whole electric energy, and that common illuminating lamp only has 30% electric energy to be used for is luminous, and all the other have changed into heat energy and have distributed to the external world.
The heat that the LED light fixture produces during because of its work is less, and luminous efficiency is higher, and is considered as cold light source.The LED light fixture is compared with traditional incandescent lamp, fluorescent lamp, and its electric energy can reach more than 90%, since it is born, with its efficient low-consume, energy-conserving and environment-protective, long characteristics of life-span, more and more has been subjected to the attention of countries in the world.The present annual electric power that only is used for street lighting of China wherein if can have 1/3 to adopt the illumination of LED lamp, just can economize on electricity about 80,000,000,000 degree just near 2,500 hundred million degree every year, and therefore, the LED illuminating lamp has become people's main R﹠D direction.
Though the LED light fixture is regarded as cold light source, still can produce certain heat during work.The operating temperature of LED device generally should be less than 50 ℃.There is data to show that when the operating temperature of LED device reaches 55 ℃, its life-span will reduce half.So present LED lamp adopts the aluminum metal shell as heat sink material for better heat radiation mostly.And aluminium is the excellence conductor of electricity, so need carry out sufficient insulation work, sets up insulating element, therefore causes the LED fitting structure complicated, has improved manufacturing cost, still has the potential safety hazard of electric leakage simultaneously.
Summary of the invention
The utility model provides the integrated ceramic LED light fixture of a kind of good heat dissipation effect, good insulating, safety at the deficiencies in the prior art.
The technology path that the utility model adopted is:
The LED light fixture comprises shell, places led board and driving power in the shell, it is characterized in that described shell is a ceramic package.
Optimally, described led board is positioned at the enclosure middle and upper part, and led board links to each other with shell by Heat Conduction Material, and heat is by shell upper and bottom conduction.
Optimally, adopt Heat Conduction Material to fill between described driving power and shell.
Optimally, described case surface is the pleat face.
Optimally, described light fixture is formed in one.
The utility model led board is to be the LED light emitting module of liner plate with the aluminium, is used to provide illuminating ray; Driving power is used for providing the energy to led board.The utility model finishes structure optimization on traditional light fixture, save a large amount of insulating materials, has dwindled small product size.
One of characteristics of the present utility model are to adopt the high-cooling property ceramic material to substitute the conventional aluminum alloy shell.Traditional aluminum alloy casing gets an electric shock in order to prevent, has adopted a large amount of insulating materials to completely cut off, increased product volume, increased the cost of product.The own insulating properties of ceramic material that the utility model shell adopts are good, can remove insulating materials loaded down with trivial details in the conventional lamp, dwindled small product size greatly, saved cost.In addition because the pottery that shell adopts among the present invention is the high-cooling property pottery, be higher than traditional aluminium alloy to the thermal conductivity of air, enclosure volume can further be dwindled, and has saved material.Because the utility model shell the is integrated heat radiation and the two big functions that insulate have also been simplified a lot on the production technology of light fixture.
For increasing radiating surface, the utility model case surface can be carried out pleating, forms the pleat face, helps increasing area of dissipation.
Because the high-cooling property pottery is the good insulation performance body, therefore, stopped the potential safety hazard of getting an electric shock, security performance is better than traditional aluminum shell.
After adopting Heat Conduction Material to fill between described driving power and shell, guaranteed the abundant heat radiation of driving power; Also fill heat radiation between led board and shell with Heat Conduction Material.
Described led board is arranged in enclosure and goes up the position, and led board links to each other with shell by Heat Conduction Material, and heat can be simultaneously to the conduction of shell upper and lower, and heat dispersion further promotes.
The utility model LED light fixture is the cavity of a sealing, characteristic with waterproof and dustproof, protection against insect, internal heat resource fully contacts with radiating element, radiating surface is big, heat conductivility is good, and the heat that LED is sent in time distributes in air, makes the LED light fixture be in all the time under the suitable operating temperature state, the life-span reduction that having avoided at high temperature works for a long time causes increases the service life effectively.
The utility model is formed in one, and has avoided the repeated use once more after the artificial destruction.The manufacturing of shell only needs a mould, has saved cost.
The high-cooling property ceramic material that the utility model adopts is a kind of broad-spectrum pottery, has conductibility, mechanical strength and heat-resisting quantity preferably, and corrosion-resistant, the wearability that this thermal diffusivity pottery is good, high rigidity are for safety provides guarantee.
