A kind of LED light fixture
Technical field
The utility model relates to field of illumination lamp technology, specifically good heat dissipation effect, effectively prevent dazzling dazzling a kind of LED light fixture.
Background technology
In order to energy-conservation and have high brightness, the key lighting light fixture in market selects LED lamp usually.The LED lamp of present use is assembled by parts such as aluminium base, radiator, LED usually.There is following problem in LED lamp conventional at present:
The area of dissipation of plum blossom hexangle type aluminium base less than 0.004 square, and easily produces between aluminium base and radiator, gap, and heat can not well be delivered to radiator from aluminium base, therefore can considerably increase light decay and the fraction defective of lamp pearl; Although the area of dissipation of bar shaped aluminium base can reach 0.01 square, due to fitting structure restriction, aluminium base heat by radiator heat-dissipation own, cannot can only be dispelled the heat by the large-area housing of light fixture, in use temperature is higher to make LED light source, has a strong impact on the service life of product.
At present the radiator of LED lamp has two kinds on the market: one is extrudate sun fancy radiator, can not fit tightly, there is heat conduction defect between the little and aluminium base of area of dissipation; Another kind of is extruding bar shaped radiator, there is the problem of the little assembling difficulty of area of dissipation equally, and the assembling screw of product reaches 63, causes production cost cost high.
The LED lamp appearance similarity degree of commercial type is high, there is serious homogeneity problem, and the lamp from dazzling of light fixture is dazzle the eyes, and front panel is that multiple parts assembly forms, and assembly cost is high, and the light fixture back side mostly is worn-out open type, and internal structure is exposed, affects attractive in appearance.
Utility model content
The purpose of this utility model is to provide a kind of LED light fixture, and to solve, existing LED light fixture radiating effect is poor, dazzling dazzling, the problem that assembly cost is higher of light.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of LED light fixture, it comprises the aluminum frame of at least 3 blocks of aluminium base light sources, rectangle, in described aluminum frame, high temperature fireproof panel, aluminium base light source, aluminum radiating bottom plate are installed from top to bottom successively, described high temperature fireproof panel is provided with lamp pearl lens carrier, lamp pearl lens are installed in lamp pearl lens carrier, LDE lamp pearl on described aluminium base light source is arranged in corresponding lamp pearl lens, base plate and the aluminum radiating bottom plate of aluminium base light source fit, and the area of aluminum radiating bottom plate is identical with the size of described aluminum frame frame inner plane.
As further improvement of the utility model, described lamp pearl lens are the inverted cone of hollow, and the inwall of lamp pearl lens is provided with reflectorized material.
Further improve as of the present utility model, described lamp pearl lens carrier is the cylinder of hollow.
The utility model is when assembling, first high temperature fireproof panel is put into the frame of aluminum frame, again lamp pearl lens carrier and lamp pearl lens are put into high temperature fireproof panel successively, again 3 blocks of aluminium base light sources are put into corresponding lamp pearl lens, build aluminum radiating bottom plate, then the utility model assembling is complete to fix screw.
The beneficial effects of the utility model are:
(1) by transformation fitting structure, make the base plate of aluminium base light source can fit tightly aluminum radiating bottom plate, and make radiating bottom plate extend to the aluminum frame inside of whole light fixture, area of dissipation is allowed to rise to 0.18 square, thus greatly reduce the environment for use temperature of LED light source, largely improve the service life of light fixture;
(2) by adding lamp pearl lens outside LED lamp bead, making light no longer dazzling dazzling, reaching anti-dazzle effect, thus the shopping desire of StoreFront purchase and consumption person and the correct judgement to article can not be had influence on;
(3) production and assembly cost of the present utility model is lower, and the panel in front develops into a monoblock high temperature fireproof panel by original multi-part composite assembly, and assembling screw, by original 63, is reduced to 34, and operation is simpler, and structure is more firm;
(4) the utility model novel appearance, by light fixture outward appearance, radiator structure and integrally-built innovation, makes light fixture overall package technique simpler, light fixture heat radiation is more reasonable, and light structure is more scientific, and local illumination intensity is higher but not dazzling, overall weight reduces, and installs lighter.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of LED light fixture as shown in Figure 1, it comprises at least 3 blocks of aluminium base light sources 5, the aluminum frame 1 of rectangle, every block aluminium base light source 5 have 7 lamp pearls at least, in aluminum frame, 1 is provided with high temperature fireproof panel 2 from top to bottom successively, aluminium base light source 5, aluminum radiating bottom plate 6, high temperature fireproof panel 2 is provided with 21 lamp pearl lens carriers 3, lamp pearl lens 4 are installed in each lamp pearl lens carrier 3, LDE lamp pearl on aluminium base light source 5 is arranged in corresponding lamp pearl lens 4, base plate and the aluminum radiating bottom plate 6 of aluminium base light source 5 fit, the area of aluminum radiating bottom plate 6 is identical with the size of aluminum frame 1 frame inner plane.
Lamp pearl lens 4 are the inverted cone of hollow, and the inwall of lamp pearl lens 4 is provided with reflectorized material.Lamp pearl lens carrier 3 is the cylinder of hollow.
The utility model is when assembling, first high temperature fireproof panel 2 is put into the frame of aluminum frame 1, again lamp pearl lens carrier 3 and lamp pearl lens 4 are put into high temperature fireproof panel 2 successively, again 3 blocks of aluminium base light sources 5 are put into corresponding lamp pearl lens 4, build aluminum radiating bottom plate 5, then the utility model assembling is complete to fix screw.
The utility model novel appearance, by light fixture outward appearance, radiator structure and integrally-built innovation, makes light fixture overall package technique simpler, light fixture heat radiation is more reasonable, and light structure is more scientific, and local illumination intensity is higher but not dazzling, overall weight reduces, and installs lighter.
