The technical solution of the large-power LED down lamp is characterized in that: the back part of the LED lamp plate is provided with a heat radiation member of which the lower end is connected with the LED lamp plate; the heat radiation member is vertically equipped with heat radiation fins; an air convection channel is equipped between two adjacent heat radiation fins; the lampshade is provided with an air inlet hole which is communicated with the air convection channel; and the upper end of the air convection channel is communicated with outside. The large-power LED down lamp of the utility model overcomes insufficiencies in the prior art and further has the following advantages: simple structure, low fabricating cost, good heat radiation effect and long service life.

Description

A kind of high-power LED tube light
[technical field]
The utility model relates to a kind of family expenses and commercial electric lighting, a kind of high-power LED tube light of more specifically saying so.
[background technology]
The luminous mode of traditional Down lamp is exactly tungsten filament short circuit and luminous or adopt fluorescent tube, so structure Design own is exactly to consider the problem of dispelling the heat.Therefore traditional Down lamp does not just have radiator structure.
The luminous principle of LED is luminous according to the principle of electron motion, will inevitably produce a large amount of heat, but temperature is high more, and light loss is big more, even can burn and do not work, so must there be good radiator structure could ensure the service life of LED.
[utility model content]
The utility model purpose is the deficiency that has overcome prior art, provides a kind of simple in structure, low cost of manufacture, good heat dissipation effect, the high-power LED tube light of long service life.
The utility model is realized through following technical scheme:
A kind of high-power LED tube light; Comprise LED lamp plate 1; Described LED lamp plate 1 is provided with LED bulb 101, and described LED lamp plate 1 below is provided with lampshade 2, it is characterized in that: described LED lamp plate 1 back is provided with the radiating piece 3 that the lower end is connected with described LED lamp plate 1; Vertically be provided with radiating fin 303 on the described radiating piece 3; Be provided with air convection channel 301 between the two adjacent described radiating fins 303, described lampshade 2 is provided with the air admission hole 202 that is communicated with described air convection channel 301, and described air convection channel 301 upper ends communicate with the external world.
Aforesaid high-power LED tube light; It is characterized in that: described radiating piece 3 is for cylindrical, and described radiating fin 303 circumference array are arranged on its outside, are provided with cavity 305 in it; Be provided with built-in power 5 in the described cavity 305, described cavity 305 upper ends are provided with escape orifice 306.
Aforesaid high-power LED tube light is characterized in that: described lampshade 2 is for tubaeform, and its upper end is connected with described radiating piece 3, and its both sides are respectively equipped with installs card 6.
Aforesaid high-power LED tube light is characterized in that: described lampshade 2 is provided with the photo engine module 7 that covers on described LED bulb 101 outsides, is provided with dust cover 8 between described LED lamp plate 1 and the described lampshade 2.
Compared with prior art, the utility model has following advantage:
1, the utility model is connected with radiating piece at the LED lamp plate back side, in radiating piece, is provided with the cross-ventilation cavity configuration, forms air convection channel, can make air form heat loss through convection, good heat dissipation effect, long service life.
2, the utility model is simple in structure, low cost of manufacture.

Fig. 2 is the utility model cut away view.
[specific embodiment]
A kind of high-power LED tube light; Comprise LED lamp plate 1; Described LED lamp plate 1 is provided with LED bulb 101, and described LED lamp plate 1 below is provided with lampshade 2, and described LED lamp plate 1 back is provided with the radiating piece 3 that the lower end is connected with described LED lamp plate 1; Vertically be provided with radiating fin 303 on the described radiating piece 3; Be provided with air convection channel 301 between the two adjacent described radiating fins 303, described lampshade 2 is provided with the air admission hole 202 that is communicated with described air convection channel 301, and described air convection channel 301 upper ends communicate with the external world.In radiating piece, be provided with the cross-ventilation cavity configuration, form air convection channel, can make air form heat loss through convection, good heat dissipation effect, long service life.
Described radiating piece 3 can be cylindrical; Also can be that the cross section is erose cylinder; Described radiating fin 303 circumference array are arranged on its outside, are provided with cavity 305 in it, are provided with built-in power 5 in the described cavity 305; Described cavity 305 upper ends are provided with escape orifice 306, and when gases are heated, they expand in the cavity 305 overflows from escape orifice 306 in the back.
Described lampshade 2 is tubaeform, and its upper end is connected with described radiating piece 3, and its both sides are respectively equipped with installs card 6, conveniently is installed on the ceiling.
Described lampshade 2 is provided with the photo engine module 7 that covers on described LED bulb 101 outsides, is provided with dust cover 8 between described LED lamp plate 1 and the described lampshade 2.Can dustproof drop into wait in, and prevent in the insect entering etc.
In radiating piece, be provided with the cross-ventilation cavity configuration; Form air convection channel, hot gas will inevitably rise after the interior air that reaches in the convection current chamber of lamp was heated, and flowed out from the radiating piece upper end; The cold air air admission hole of will flowing through in the lampshade gets into the convection current chamber and forms convection current; Improve radiating effect greatly, can ensure that the life-span of LED reaches 100,000 hours.
