Abstract
A kind of large area light emitting LED light, it is characterised in that it, which includes the ceramic aluminum substrate (1) with one group of LED lamp bead, refractive body (2) and micromachine (3), the utility model advantage, is：1st, by the reflecting coating layer being arranged on refractive body, light beam is concentrated, increases its length of illumination；2nd, can be achieved to change light luminance intensity by the rotation of refractive body；When the 3rd, being rotated by one group of cooling blade being arranged on refractive body by motor, ceramic aluminum substrate temperature can be reduced.
Description
Technical field
The utility model is related to the LED fields, and in particular to a kind of large area light emitting LED light.
Background technology
At present, the demand illuminated with LED is increasingly urgent, and the development of great power LED lamp is taken seriously increasingly, and
Existing LED lamp beads length of illumination is smaller, is limited length of illumination, and LED lamp beads work long hours after temperature it is excessively high, lead
The quality of great power LED lamp bead is caused to be limited, greatly reduces the luminous efficiency and service life of great power LED lamp bead, from
And hinder the development of great power LED lamp bead.
Utility model content
The purpose of this utility model is increasingly urgent aiming at the demand illuminated now with LED, great power LED lamp
Development be taken seriously increasingly, and existing LED lamp beads length of illumination is smaller, is limited length of illumination, and LED lamp beads are long
Temperature is excessively high after time service, and the quality of great power LED lamp bead is caused to be limited, and greatly reduces great power LED lamp bead
Luminous efficiency and service life so as to hinder the deficiency of the development of great power LED lamp bead, and provide a kind of large area light emitting
LED light.
The utility model includes ceramic aluminum substrate, refractive body and micromachine with one group of LED lamp bead,
Circular array shows one group of loss of weight gap on ceramic aluminum substrate with one group of LED lamp bead,
Setting is fluted at center on ceramic aluminum substrate with one group of LED lamp bead, and hole, hole are provided at the center of groove
Bearing is inside fixed with,
Refractive body is hollow luminous body, and one layer of heat-absorbing material for heat absorption is coated on the inner surface of refractive body,
The outer surface of refractive body is covered with rear reflector or coated with reflecting coating layer,
Shaft is provided on refractive body,
Refractive body is located in groove, and shaft on refractive body and the inner ring of bearing are connected,
The power output shaft of micromachine drives shaft to rotate by bevel gear set.
Refractive body is spherosome, cylinder or tri-prismoid.
Rear reflector or coated with reflecting coating layer by the rear reflector of multiple and different colors or coated with reflecting coating layer
Composition.
There is one group of cooling blade on refractive body respectively in a ring, cool down the spacing between the top of blade and ceramic aluminum substrate
For 5-10mm.
Groove is the groove that surface is shiny surface.
The utility model advantage is：1st, by the reflecting coating layer being arranged on refractive body, light beam is concentrated, increases its hair

Specific embodiment
As shown in the figure, the utility model includes the ceramic aluminum substrate 1 with one group of LED lamp bead, refractive body 2 and miniature
Motor 3,
Circular array shows one group of loss of weight gap on ceramic aluminum substrate 1 with one group of LED lamp bead,
Setting is fluted at center on ceramic aluminum substrate 1 with one group of LED lamp bead, and hole is provided at the center of groove,
Bearing is fixed in hole,
Refractive body 2 is hollow luminous body, and one layer of heat-absorbing material for heat absorption is coated on the inner surface of refractive body 2,
The outer surface of refractive body 2 is covered with rear reflector or coated with reflecting coating layer,
Shaft is provided on refractive body 2,
Refractive body 2 is located in groove, and shaft on refractive body 2 and the inner ring of bearing are connected,
The power output shaft of micromachine 3 drives shaft to rotate by bevel gear set.
Refractive body 2 is spherosome, cylinder or tri-prismoid.
Rear reflector or coated with reflecting coating layer by the rear reflector of multiple and different colors or coated with reflecting coating layer
Composition.
There is one group of cooling blade 4 on refractive body 2 respectively in a ring, cool down between the top of blade and ceramic aluminum substrate 1
Spacing is 5-10mm.
Operation principle：Refractive body 2 is covered with rear reflector by being arranged on outer surface or makes light coated with reflecting coating layer
In constriction, increase its length of illumination；And pass through heat-absorbing material and temperature is absorbed into refractive body 2,1 temperature of ceramic aluminum substrate can be reduced
Degree drives refractive body 2 to rotate and can reach the effect of cooling by micromachine 3, can also drive one group on refractive body 2 it is cold
But blade 4, which forms cooling wind, reduces temperature.
Refractive body 2 is contacted with groove or not contacted, when not contacting should between groove distance 1-1.5MM.
