Abstract
The utility model discloses a high power LED (light-emitting diode) ceiling lamp, which comprises a polygonal prism shaped ceiling lamp body including a regular polygonal or rectangular heat emission bottom board and a lamp frame positioned on and tightly connected with the heat emission bottom; a plurality of narrow aluminium substrate strips are disposed at the center of the heat emission bottom board; a plurality of LED lamp beams are disposed on each aluminium substrate strip; a light pervious cover is disposed under the aluminium substrate strips; light dispersing strips are disposed one side surfaces of the ceiling lamp body. The lights from the LED lamp beads are softened by refraction, reflection and dispersion by the light pervious cover and the light dispersing strips on the sides; and then distributed to the whole lighting space uniformly.
Description
Technical field
The utility model relates to a kind of lighting device, is specifically related to the great power LED ceiling light of a kind of single led lamp pearl power greater than 0.3W.
Background technology
Traditional ceiling light many with fluorescent tube as light source because structure and characteristic that fluorescent tube itself is had, make the ceiling light of the type exist that power consumption is big, lack service life and the defective of not environmental protection.Be directed to this, people gradually adopt the LED ceiling light to replace traditional ceiling light, existing LED ceiling light uses the LED fluorescent tube to replace fluorescent tube on the basis of traditional ceiling light and simplifies the lamp bracket of traditional ceiling light and constitute, than traditional ceiling light, it has plurality of advantages such as low energy consumption, high light efficiency, long service life, environmental protection, but also exist following defective: the ceiling light that 1, adopts the great power LED fluorescent tube, its brightness is too high, cause the irradiated area bright excessively, though the part ceiling light is provided with light barrier or astigmatism plate, still there is the even phenomenon of uneven illumination; 2, the heat that produced of LED fluorescent tube is bigger, in case heat can't distribute fast effectively and be accumulated in the fluorescent tube, cause the operating temperature in the body too high easily, and then influence service life of LED fluorescent tube, and the part ceiling light is in order to quicken heat radiation, on ceiling light, be equipped with large-scale radiator, cause the weight of whole lamp body big, security performance is not high.
Summary of the invention
In order to address the above problem, the utility model provide a kind of simple in structure, weight is little, thermal diffusivity good, the uniform great power LED ceiling light of illumination.
The utility model is that the technical scheme that its problem of solution is adopted is:
A kind of great power LED ceiling light, comprise the ceiling light main body that is polygon prism, the ceiling light main body comprise be regular polygon or rectangular radiating bottom plate and be positioned at the radiating bottom plate top and with the close-connected lamp bracket of radiating bottom plate, the middle part of described radiating bottom plate upper surface is provided with the aluminium base lath of many narrow strip, described every aluminium base lath is provided with several LED lamp pearls, the below of aluminium base lath is provided with a diffuser, and the side of ceiling light main body is provided with astigmatic bar.
In the utility model, described astigmatic bar comprises many glass bars that be arranged in parallel.
In the utility model, described astigmatic bar parallels with each edge of ceiling light main body.
In the utility model, each angle of described ceiling light main body is provided with Transparent lamp shade, is provided with secondary LED lamp pearl in the Transparent lamp shade.
In the utility model, described secondary LED lamp pearl is connected with radiating bottom plate by heat conducting bar.
The beneficial effects of the utility model are: the light that LED lamp pearl sends in the utility model is by refraction, reflection, the scattering process of light-passing board and side astigmatism bar, make light soft, be evenly distributed in whole lighting space; Further, LED lamp pearl is installed on the radiating bottom plate by the aluminium base lath of bar narrow strip, the heat that LED lamp pearl comes out is directly transferred on radiating bottom plate and the lamp bracket by aluminium base lath, radiating bottom plate and lamp bracket promptly diffuse to heat in the air and go, not only accelerated the heat radiation of LED lamp pearl, reduced operating temperature effectively, increased the service life of lamp pearl, also reduced special-purpose radiator, reduced the weight of whole ceiling light, and in the utility model aluminium base lath is made into narrow strip, and can save the area of aluminium base lath widely, reduce manufacturing cost.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of present embodiment;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is the A part enlarged drawing of Fig. 1.
The specific embodiment
Referring to figs. 1 through Fig. 3, provided by the utility model a kind of simple in structure, weight is little, thermal diffusivity good, the uniform great power LED ceiling light of illumination, it comprises: comprise the ceiling light main body that is four arris cylinders, the ceiling light main body comprise be foursquare radiating bottom plate 1 and be positioned at radiating bottom plate 1 top and with radiating bottom plate 1 close-connected lamp bracket 2, radiating bottom plate 1 and lamp bracket 2 are made by the good aluminum alloy materials of thermal conductivity, and the heat on the radiating bottom plate 1 can be delivered to rapidly on the lamp bracket 2 and by lamp bracket 2 and be dispersed in the air; The middle part of radiating bottom plate 1 upper surface is provided with the aluminium base lath 3 of many narrow strip, many aluminium base laths 3 are parallel to each other and are arranged in evenly and at intervals on the radiating bottom plate 1, described every aluminium base lath 3 is provided with several LED lamp pearls 4, the below of aluminium base lath 3 is provided with a square diffuser 5, and the side of ceiling light main body is provided with astigmatic bar 6.
As preferred embodiment, each angle of described ceiling light main body is provided with Transparent lamp shade 7, be provided with secondary LED lamp pearl 71 in the Transparent lamp shade 7, the light that secondary LED lamp pearl 71 sends can be radiated at each corner of lighting space equably, make whole lighting space brightness even, the Transparent lamp shade 7 at each angle is just being positioned in the middle of astigmatic bar 6 on each bar limit is stuck in, and makes the astigmatic bar 6 can not move left and right, increased its security performance.And secondary LED lamp pearl 71 is connected with radiating bottom plate 1 by heat conducting bar 8, has accelerated the efficient of its heat radiation, for the long-time use of secondary LED lamp pearl 71 provides sound assurance.
In this example, described astigmatic bar 6 comprises many glass bars that be arranged in parallel, and glass bar parallels with each edge of ceiling light main body, and the light transmission of glass bar is good, and cheap, is fit to large-scale production.Produce for convenience, glass bar is installed in the below of radiating bottom plate 1 by connector.Certainly, herein, described astigmatic bar 5 can also have identical effect for the light transmission strip of being made by transparent plastic or acrylic sheet material, is its equal technical scheme.For the structure that makes whole ceiling light is compact more, be installed in the lamp bracket 2 for the constant-current supply 9 of LED lamp pearl 4 and 71 power supplies of secondary LED lamp pearl.
Further, softer in order to make light, be provided with a plurality of crystal balls at the periphery of diffuser 5, crystal ball is between diffuser 5 and astigmatic bar 6.
In the present embodiment, the single lamp pearl power of described LED lamp pearl 4 and secondary LED lamp pearl 71 is all greater than 0.3W.
