Abstract
The utility model discloses a light guide column type daylight lamp. The light guide column type daylight lamp comprises a light guide column, at least one light-emitting component, a radiator, a plastic shell and a power source. The light guide column is provided with a horizontal reflection surface and an arc-shaped emitting surface which are arranged opposite to each other, and the reflection surface is provided with a layer of reflection film. The light-emitting components are arranged on the end face of the light guide column, and light rays emitted from the light-emitting components enter into the light guide column through the end face of the light guide column and are emitted out from the emitting surface after being reflected by the reflection surface. The radiator is connected with the light-emitting components and placed outside the light guide column. The plastic shell covers the light-emitting components and the radiator inside, a power source cavity is arranged inside the plastic shell, a plurality of air runners are arranged on the plastic shell, and two ends outside the plastic shell are respectively provided with lead pins. The power source is arranged in the power source cavity. The light guide column type daylight lamp is attractive, low in dazzle light, good in radiation, and long in service life.
Description
Technical field
The utility model relates to a kind of fluorescent lamp, relates in particular to a kind of leaded light column type fluorescent lamp.
Background technology
At present, the LED fluorescent lamp is as a kind of house lighting for alternative tengsten lamp and fluorescent lamp, because it has that energy consumption is little, light efficiency is large, without advantages such as mercury, radiationless pollution and material reproducible utilizations, in today of energy growing tension, more and more be subject to consumer's welcome.
At present, the LED fluorescent lamp all with many granule LED arrange form a string to make the fluorescent tube shape, the LED fluorescent lamp wherein had adopts the integral plastics pipe as shell, this structure has no heat radiation and can say, also have plenty of the half of aluminum pipe of employing and half of plastic face mask, power supply is arranged in the body of aluminum pipe and plastic face mask composition, though this result has good thermal diffusivity, but the temperature in pipe can directly affect power supply, the power supply long-term work can cause shorten its service life under hot environment, thereby affects the service life of whole fluorescent lamp.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of good heat dissipation, the leaded light column type fluorescent lamp of long service life
.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of leaded light column type fluorescent lamp comprises:
One light-guiding pillar, have relative horizontal reflection face and arc light-emitting area, is provided with one deck reflectance coating on described reflecting surface;
At least one light-emitting component, be arranged at the end of described light-guiding pillar, and the light that described light-emitting component sends enters described light-guiding pillar via the end face of described light-guiding pillar, and penetrate from described light-emitting area via described reflecting surface reflection;
Radiator, be connected with described light-emitting component, and be positioned at described light-guiding pillar outside;
One plastic casing, described light-emitting component and described radiator are coated on to described plastic casing inside, and described plastic casing inside also has the power supply cavity, has a plurality of air flow channels on described plastic casing, the two ends of described plastic casing outside are respectively arranged with draws pin, and
Power supply, be positioned at described power supply cavity.
Described light-emitting component is two, and is arranged at respectively the two ends of described light-guiding pillar.
Described light-emitting component comprises circuit substrate, and the front of described circuit substrate is provided with a plurality of LED, and the back side of described circuit substrate is connected with described radiator.
Compared with prior art, the beneficial effects of the utility model are:
1. because leaded light column type fluorescent lamp of the present utility model arranges light-emitting component in the side of light-guiding pillar, the good like this heat dissipation problem that solved, thus high-power LED can be used, strengthen illuminating effect, simultaneously attractive in appearance and to dazzle light low, in addition, the power supply cavity in plastic casing is isolated power supply and thermal source fully, and the temperature of LED lamp and power supply temperature can not disturbed mutually, thereby is protected the service life of power supply, therefore not only the light of dazzling attractive in appearance is low for the utility model, and good heat dissipation, and service life is longer.
The accompanying drawing explanation
Describe the utility model in detail below in conjunction with drawings and embodiments:
Fig. 1 is structural representation of the present utility model.
The side that Fig. 2 is the described light-guiding pillar of Fig. 1.
In figure: light-guiding pillar 2, light-emitting component 4, radiator 6, plastic casing 8, reflecting surface 21, light-emitting area 22, reflectance coating 23, power supply 81, draw pin 82, circuit substrate 41, LED 42.
The specific embodiment
As shown in Figure 1, a kind of leaded light column type lightening lamp tool of the present utility model, comprise: light-guiding pillar 2, light-emitting component 4, radiator 6 and plastic casing 8, wherein light-guiding pillar 2(is referring to Fig. 2), there is relative a reflecting surface 21 and light-emitting area 22, reflecting surface 21 is to be provided with one deck reflectance coating 23 on a horizontal plane and its, and light-emitting area 22 is an arc surface.Two light-emitting components 4 are arranged on respectively on the end face of both sides of light-guiding pillar 2, the light that light-emitting component 4 sends enters light-guiding pillar 2 via the end face of light-guiding pillar 2, via reflectance coating 23 reflections on reflecting surface 21, from light-emitting area 22, penetrate again, be connected with respectively a radiator 6 on two light-emitting components 4, plastic casing 8 is coated on its inside by the radiator 6 at light-guiding pillar 2 two ends and light-emitting component 4, and section also is formed with the power supply cavity within it, be provided with power supply 81 in this power supply cavity, there are a plurality of air flow channels (not shown) on plastic casing 8, the effect of this air flow channel is to realize the heat exchange of plastic casing 8 internal heat air-flows and its outer gas stream, strengthen the thermal diffusivity of invention, the two ends of plastic casing 8 outsides are respectively arranged with draws pin 82, this draw pin 82 concrete be positioned at position on the lower, plastic casing two ends, power supply cavity in plastic casing 8 is isolated power supply 81 and thermal source fully, the temperature of LED lamp and power supply temperature can not disturbed mutually, thereby is protected the service life of power supply.
