Abstract
The utility model relates to an LED light emitting module using ceramic for heat dissipation. The LED light emitting module includes a ceramic heat dissipation base, a circuit board is fixed on one surface of the ceramic heat dissipation base, an LED light emitting set is connected with the circuit board and comprises a plurality of LEDs, a non-transparent lampshade is fixed above the LED light emitting set; and heat dissipation fins protruded outwards are arranged on the other surface of the ceramic heat dissipation base and are also made of ceramic. The heat dissipation fins and the ceramic heat dissipation base are made of the ceramic, and the heat energy generated by the LED light emitting set can be rapidly absorbed and dissipated through utilizing the ceramic physical properties of high conductivity and high radiation, thereby ensuring that the LED light emitting set is in a constant low temperature state and can operate stably and continuously, and prolonging the LED service life.
Description
Technical field
The utility model relates to a kind of LED light emitting module, especially relates to a kind of LED light emitting module that uses ceramic heat-dissipating.
Background technology
LED is a kind of solid-state semiconductor devices, and it can directly be converted into light to electricity.The heart of LED is a semi-conductive wafer, and an end of wafer is attached on the support, and an end is a negative pole, and the other end connects the positive pole of power supply, makes entire wafer by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is a P-type semiconductor, occupies an leading position in its hole, the inside, and the other end is a N-type semiconductor, mainly is electronics here.But when these two kinds of semiconductors couple together, just form a P-N knot between them.When electric current acted on this wafer by lead, electronics will be pushed to the P district, and electronics will send energy with the form of photon, the luminous principle of LED that Here it is then with hole-recombination in the P district.
The LED light fixture is because heat radiation is big, if can not in time dispel the heat, especially great power LED will burn electronic devices and components after of long duration, has influence on that the LED light fixture is normal to be used and the life-span.
Use heat abstractor on the market typically uses the heat dissipation metal mode now, but heat dissipation metal does not use the effect of ceramic material heat radiation better.
Summary of the invention
The utility model has designed a kind of LED light emitting module that uses ceramic heat-dissipating, and the technical problem of its solution is the service life that (1) existing bad meeting of LED heat sinking function has influence on light fixture; (2) the LED light emitting module is in order to reach certain essential many LED of sufficient amount that use of brightness of illumination.
In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of LED light emitting module with ceramic heat-dissipating effect, comprise the ceramic heat-dissipating pedestal, a fixing circuit board at described ceramic heat-dissipating pedestal, be connected with luminous group of LED at described circuit board, luminous group of described LED is made of a plurality of LED, is provided with a nontransparent lampshade in luminous group of upper fixed of described LED; Another side at described ceramic heat-dissipating pedestal is provided with outwards outstanding radiating fin, and described radiating fin also is a ceramic material.
Further, described LED surface scribbles ZnS base nano fluorescent bisque.
Further, described radiating fin and described ceramic heat-dissipating pedestal are integral piece.
Further, described radiating fin is columned heat radiation projection.
Further, described radiating fin is the heat radiation projection of square shape.
The LED light emitting module of this use ceramic heat-dissipating is compared with the conventional metals cooling base, has following beneficial effect:
(1) the utility model is because the material of radiating fin and ceramic heat-dissipating pedestal is a ceramic material, utilize the high conduction and the high radiation physics characteristic of ceramic material, can and leave luminous group of heat energy fast Absorption that produces of LED, guarantee that luminous group of LED is in a constant low temperature state, and can stablize and lasting running, thereby can prolong the service life of LED.
(2) the utility model is owing to scribble ZnS base nano fluorescent bisque on the LED surface, nano level ZnS base fluorescent powder can distribute uniformly and can be so that light emitting diode sends luminous energy through brighter behind the nano-phosphor, compare with the light emitting diode that scribbles common phosphors, under equal-wattage, can reach 1.5 times of its brightness of illumination, thereby can under the requirement of same brightness, can reduce the quantity that LED uses.
