Description

A kind of great power LED illumination of plant building ceiling light

Technical field

The utility model relates to a kind of high-power LED lamp, relates in particular to a kind of great power LED illumination of plant building ceiling light.

Background technology

The LED principle of luminosity is solid luminescence, by the solid luminescence physics principle, the spectrum of LED almost all concentrates on visible light frequency band, so luminous efficiency is up to more than 90%, therefore, LED is described as the 21 century new light sources, LED can be divided into great power LED and low-power LED by power, with great power LED as illuminator, the product of same luminous flux, the pipe number of usefulness can lack, optical efficiency is higher, supporting wiring board and installation procedure can be simplified, yet the heat radiation of great power LED is the difficult problem of professional, have limited the range of application of great power LED.

Existing all kinds of great power LED illumination of plant building ceiling light, kind is more, but all be the great power LED circuit plate that constitutes by great power LED and printed circuit board (PCB) basically, the lampshade that constitutes by lamp socket and housing, be contained in the outer various forms of heat abstractors of lampshade and constitute.Its housing just plays the led circuit plate is covered, and prevents or reduces dust and drop on effect on the great power LED circuit plate.

Adopt the great power LED illumination of plant building ceiling light of this form of the composition certainly to solve heat dissipation problem, and normal the use, but every kind of high-power LED lamp all need design its cooling system respectively, and design efficiency is low.Aggravation along with industry competition, such form of the composition can not adapt to the requirement of the new product development that the cycle shortens day by day, though housing can play the led circuit plate is covered, prevent or reduce dust and drop on effect on the great power LED circuit plate, but outside heat abstractor is exposed to, and the overhead type light fixture, the position height, safeguard inconvenience, its heat abstractor is again up mostly, and the production environment of industrial premises much is again that abominable relatively, a large amount of dust drops on and causes heat radiating device thermal resistance to become big on the heat abstractor probably, the heat dispersion variation shortens service life of great power LED luminous tube.

The utility model content

In order to overcome the deficiency of existing high-power LED lamp, the utility model provides a kind of great power LED illumination of plant building ceiling light, its great power LED circuit plate luminescence component and heat abstractor are assemblys, can be used as assembly of elements, heat abstractor is arranged in the housing, can prevent or reduce dust simultaneously and drop on led circuit plate and the heat abstractor.

The purpose of this utility model is to realize by following technical scheme, a kind of great power LED illumination of plant building ceiling light, the lampshade, the heat abstractor that comprise the great power LED circuit plate that is made of great power LED and printed circuit board (PCB), be made of lamp socket and housing; Great power LED circuit plate is arranged on the interior lamp socket of lampshade; The great power LED circuit plate luminescence component that is arranged in the lampshade is no less than two groups, and each is organized the luminescence component branch and is located at the interior diverse location of lampshade, and each back side of organizing great power LED circuit plate is equipped with heat abstractor; Heat abstractor integral body is located in the lampshade.

The described led circuit plate luminescence component of respectively organizing is located on the interior Different Plane of lampshade.

Angle in obtuse angle between the described mounting plane of respectively organizing led circuit plate luminescence component.

The circuit board of described LED is an aluminium base, and great power LED is mounted on the aluminium base, and heat abstractor is the bar finned heatsink, and the installed surface of fin is close to the aluminium base back side and is connected, and fin integral body is located in the housing.

The beneficial effects of the utility model are: because the great power LED circuit plate luminescence component that is arranged in the lampshade is no less than two groups, each is organized the luminescence component branch and is located at the interior diverse location of lampshade, each back side of organizing great power LED circuit plate is equipped with heat abstractor, can be with the assembly of great power LED circuit plate luminescence component and heat abstractor as assembly of elements, all kinds of high-power LED lamps are as long as carry out permutation and combination flexibly according to different demands with the diverse location of these parts in various lampshade, need not design cooling system respectively again, can improve the flexibility and the efficient of design greatly.Help the products innovation and the large-scale production of all kinds of high-power LED lamps.Because heat abstractor is arranged in the housing, can prevent or reduce dust simultaneously drops on led circuit plate and the heat abstractor, avoid dust to drop on and cause heat radiating device thermal resistance to become big on the heat abstractor, heat dispersion variation, thereby the service life of prolongation great power LED luminous tube.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.Wherein:

Fig. 1 is the decomposing schematic representation of a kind of embodiment of the utility model;

Fig. 2 is the assembling schematic diagram of a kind of embodiment of the utility model.

The specific embodiment

The structure of a kind of embodiment of the utility model, as shown in Figure 1 and Figure 2, a kind of great power LED illumination of plant building ceiling light, the lampshade, the heat abstractor that comprise the great power LED circuit plate 3 that constitutes by great power LED and printed circuit board (PCB), constitute by lamp socket 4 and housing 1; Great power LED circuit plate 3 is arranged on the interior lamp socket 4 of lampshade; Great power LED circuit plate 3 luminescence components that are arranged in the lampshade are no less than two groups, and each is organized the luminescence component branch and is located at the interior diverse location of lampshade, and each back side of organizing great power LED circuit plate 3 is equipped with heat abstractor; Heat abstractor integral body is located in the lampshade.
