Abstract
The utility model discloses the field of LED lamps, in particular a wide-angle LED daylight lamp. The wide-angle LED daylight lamp comprises a lamp shell, a lamp panel assembly and two lamp holders, wherein the lamp shell comprises a lamp cover and a heat radiator which are mutually buckled, the lamp panel assembly is arranged in the lamp shell, two ends of the lamp shell are independently sleeved on the lamp holder, the cross section of the lamp cover is of an optimal arc shape, the cross section of the heat radiator is of a minor arc shape, the area of the lamp cover occupies two-thirds that of the lamp shell, a rib plate is arranged on the heat radiator and positioned on the place of the heat radiator, which is close to an arc port, and the lamp panel assembly is fixed on the rib plate. The wide-angle LED daylight lamp can solve the technical defect of small light spreading area caused by a lighting angle of basically less or equal 180 degrees of the traditional LED tube, and has the advantages of large lighting angle, good light diffusing effect, good heat radiating effect, high stability and long service life.
Description
Technical field
The utility model relates to a kind of LED lamp, particularly extensive angle LED fluorescent lamp.
Background technology
In recent years; Based on characteristics such as energy-saving and environmental protection, high efficiency, small size, long-lives; LED (Light Emitting Diode, light emitting diode) light fixture more and more receives people's favor, and the LED light fixture replaces traditional incandescent lamp to become a kind of main flow trend with fluorescent lamp.
Existing LED fluorescent lamp generally comprises lampshade, lamp plate assembly and shell, but existing LED fluorescent tube light angle basic≤180 °, it is extensive inadequately to expand light area.
The utility model content
The purpose of the utility model is to provide a kind of lighting angle big for the deficiency that solves above-mentioned prior art, the extensive angle LED fluorescent lamp that astigmatism is effective.
To achieve these goals, the extensive angle LED fluorescent lamp that the utility model designed comprises lamp housing, lamp plate assembly and two lamp holders; Said lamp housing is made up of the lampshade and the radiator of mutual fastening, and the lamp plate assembly is positioned at lamp housing, and the lamp housing two ends are all independently overlapped and connected a lamp holder; The cross section of said lampshade is the major arc shape; The cross section of said radiator is the minor arc shape, and the lampshade area accounts for more than 2/3rds of lamp housing area, on radiator, is provided with floor; Said floor is positioned on the radiator near the position of nock, and the lamp plate assembly is fixed on the floor.
Because the cross section of lampshade is the major arc shape, the lampshade area accounts for more than 2/3rds of lamp housing area again simultaneously in the said structure, makes that the lighting angle of lamp plate assembly can be more than 180 ° in the utility model, and astigmatism is effective.
Because the lamp plate assembly in use can produce great amount of heat; In order to guarantee the stability in use of lamp plate assembly; Need above-mentioned heat be loose through radiator fast and remove, the lamp plate assembly in said the utility model is bonded on the floor of radiator through the bond plies band.
The extensive angle LED fluorescent lamp that the utility model obtains, the cross section of its lampshade are the major arc shape, and simultaneously the lampshade area accounts for more than 2/3rds of lamp housing area again, make that the lighting angle of lamp plate assembly can be more than 180 ° in the utility model, and astigmatism is effective; Also have the good heat dissipation effect of the utility model, in light weight, stability in use is high, long service life.
Description of drawings
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the cross sectional representation of lampshade among the embodiment 1;
Fig. 3 is the cross sectional representation of radiator among the embodiment 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment 1:
Like the extensive angle LED fluorescent lamp among Fig. 1, it comprises lamp housing 1, lamp plate assembly 3 and two lamp holders 2, and said lamp housing 1 is made up of the lampshade 1-2 and the radiator 1-1 of mutual fastening; Lamp plate assembly 3 is positioned at lamp housing 1, and lamp housing 1 two ends are all independently overlapped and connected a lamp holder 2, and are as shown in Figure 2; The cross section of said lampshade 1-2 is the major arc shape; As shown in Figure 3, the cross section of said radiator 1-1 is the minor arc shape, and lampshade 1-2 area accounts for 3/4ths of lamp housing 1 area; Said structure makes that the lighting angle of lamp plate assembly 3 can reach about 260 ° in the present embodiment, and astigmatism is effective; Because lamp plate assembly 3 in use can produce great amount of heat; In order to guarantee the stability in use of lamp plate assembly 3; Need above-mentioned heat be loose through radiator 1-1 fast and remove; Therefore the radiator 1-1 in the present embodiment is provided with floor 4, and said floor 4 is positioned at radiator 1-1 and goes up the position near nock, and lamp plate assembly 3 is bonded on the floor 4 through bond plies band 5.
