Abstract
The utility model discloses an LED lamp with double-layer tubes. The LED lamp comprises tubes, side covers and LED lamp bars, wherein the LED lamp bars are arranged in the tubes, the side covers are installed at both ends of the tubes, and the tubes comprises plastic layers and aluminum alloy housings sleeved over the external surfaces of the plastic layers. The LED lamp can be used in an environment of high humility, has excellent heat dissipation function, and is simple and stable in structure, and long in service lifetime. Moreover, the LED lamp is non-deformable.
Description
Technical field
The utility model relates to lighting, relates in particular to a kind of LED lamp of double-decker fluorescent tube.
Background technology
Traditional incandescent lamp is that the filament energising is heated to incandescent state, utilizes heat radiation to send the electric light source of visible light.Shortcomings such as conventional incandescent is owing to big energy-consuming, and heat dissipation capacity is big, and the life-span is short are substituted by the LED lamp gradually, and being widely used of LED lamp become a kind of trend gradually.
The LED light emitting diode is a kind of solid-state semiconductor devices, can directly be converted into light to electricity.The LED light emitting diode has plurality of advantages such as energy consumption is low, pollution-free, radiationless, volume is little, brightness is high, the life-span is long, belong to by universally acknowledged environmental protection light source, national governments all encourage growth LED technology with energy savings.
Be applied to the LED fluorescent tube of outdoor lighting or high humidity environment at present, mostly with LED lamp bar sealant pouring and sealing in the plastic cement pipe, reach certain moisture effect, but this structure is unfavorable for fluorescent tube heat radiation.Other LED fluorescent tube is sealant pouring and sealing LED lamp bar in the heat radiation aluminium extruded, but this structure operation is complicated, and product can not be repaired.
The utility model content
The utility model has overcome deficiency of the prior art, and a kind of LED lamp of the double-decker fluorescent tube that both combine with protection against the tide that will dispel the heat is provided.
In order to realize above-mentioned purpose, adopt following technical scheme:
A kind of LED lamp of double-decker fluorescent tube comprises fluorescent tube, side cover and LED lamp bar, and LED lamp bar is arranged on fluorescent tube inside, and side cover is installed in lamp tube ends, and said fluorescent tube comprises plastic layer and aluminum alloy casing, and said aluminum alloy casing is enclosed within the outer surface of plastic layer.The plastic layer of fluorescent tube can play dampproof effect, even the LED lamp also can operate as normal under the environment of high humility.But plastic layer is wanted the then necessary tight LED of the wrapping lamp bar of the purpose that reaches moistureproof, the heat radiation in the time of can hindering the work of LED lamp bar like this, and the aluminum alloy casing that is enclosed within the plastic layer surface then plays the effect of heat radiation, and the LED lamp can not damaged because of high temperature.Aluminum alloy casing can also increase the intensity of fluorescent tube, prevents that fluorescent tube is out of shape easily.
In the such scheme, translucent construction that said plastic layer is formed in one and reflective structure, aluminum alloy casing are enclosed within the outer surface of reflective structure.Be installed in the translucent construction that light that the inner LED lamp bar of fluorescent tube sends sees through plastic layer and shine the outside, and the light that the reflective structure reflection is not broken forth makes these light have an opportunity to penetrate from translucent construction, reduces the loss again.Said reflective structure set inside has the screens that LED lamp bar is installed, and LED lamp bar is installed in the screens, and the heat of generation is transmitted to aluminum alloy casing through reflective structure and dispels the heat.
In the such scheme, said side cover is provided with the conducting metal pin, is connected with LED lamp bar.Two side covers are provided with the conducting metal pin, are communicated with an end arbitrarily and all can light LED lamp bar.Said lamp tube ends adopts sealant sealing to irritate, and improves the sealing of fluorescent tube, further strengthens moistureproof effect.
Compared with prior art, the utility model can be used for the environment of high humility, and good heat sinking function is arranged again, and simple in structure and firm, not yielding, long service life.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model;
Fig. 2 is the side sectional view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
The overall structure of the utility model is as shown in Figure 1, and the side is as shown in Figure 2.The LED lamp of this double-decker fluorescent tube includes fluorescent tube 1, side cover 2 and LED lamp bar 6, and side cover 2 is installed in the two ends of fluorescent tube 1, and LED lamp bar 6 is installed in the inside of fluorescent tube 1, and side cover 2 is provided with the conducting metal pin and is connected with LED lamp bar 6.
During installation, aluminum alloy casing 3 is enclosed within formation fluorescent tube 1 on the plastic layer, is installed in LED lamp bar 6 in the screens, cover side cover 2 again, the conducting metal pin on the side cover 2 is connected with LED lamp bar, accomplishes and installs.During work, the light that LED lamp bar 6 sends is gone out from translucent construction 4 transmissions, and the heat that produces is transmitted to aluminum alloy casing 3 through ray structure 5 and dispels the heat.
