Description

A kind of LED lamp

Technical field

The utility model relates to lighting, particularly a kind of LED lamp.

Background technology

Along with the development of urban construction, road construction is day by day perfect, and illuminating street lamp shared proportion in city illumination system is increasing, simultaneously also outstanding all the more with the contradiction of power shortage, adopts new illuminating street lamp to replace the requirement of existing street lamp just more urgent.And there is very large advantage as a kind of new lighting engineering in LED, the advantages such as long working life, luminous efficiency are high, power saving that it has.

But the luminescence mechanism of LED has determined that the power of LED can not be very high.Therefore, high-power LED lighting fixture, as LED street lamp or LED Tunnel Lamp etc., is substantially all multiple LED that distribute on a LED substrate, thereby realizes the illumination needs of higher-wattage, high brightness.But the heat problem that multiple LED produce can not be ignored.Therefore,, in order to improve the service life of high-power LED lamp, need to solve the heating problem of LED substrate.Although existing high-power LED lighting fixture possesses radiator structure, effect is not ideal enough.Or adopt the heat radiation of fin shape, because dust stratification dirt after long-term use causes radiating effect to decline.

In addition, existing high-power LED lighting fixture always basis is applied to different occasions, and proposes corresponding fitting structure design.The LED fitting structure of different applications differs greatly, as completely different with LED Tunnel Lamp structure in LED lamp post structure, therefore can not be general.

Utility model content

For the problems referred to above that exist in prior art, the utility model proposes the LED lamp that a kind of radiating effect is good.

The utility model adopts following technical scheme: a kind of LED lamp, comprise shell, be arranged at the plural LEDs on shell, be fixed on shell and be positioned at the diffuser of LED top, on 6 side panels of described shell, all offer passage, in the cavity volume of described shell, be provided with the heating column of the complex root aluminum that connects its upper panel and downside panel, in the cavity volume of described shell, be provided with the fixing base of 2 semicircle elongated slot bodies formations that are individually fixed in its upper panel and downside panel, described fixing base is laterally between the Left-Hand Panel and right panel of shell.

Further improved: 2 described semicircle elongated slot bodies are sealed and form the fixing base of circular elongated slot body by bolt.

Further improved: when described LED lamp is used for tunnel illumination, described LED is arranged at the middle position on shell, and described shell is fixed thereon a tunnel by fixed screw with mounting bracket.

Further improved: the angle of described mounting bracket is adjustable.

It is further improved: when described LED lamp is used for road lighting, described LED is arranged at the end position of keeping right on shell, the Left-Hand Panel of described shell is offered a through hole, and described shell is fixed thereon a road body of rod by the fixing base of establishing in its cavity volume.

Further improved: on described fixing base, to also have an elastic fastener.

Further improved: in described fixing base, to be provided with a stator.

Further improved: described heating column is 20.

The utility model adopts as above technical scheme, and tool has the following advantages:

1. be connected by the heating column in the cavity volume of shell and form a stack effect and produce, and there is cross-ventilated passage all around, upper and lower several sides, strengthened the circulation of air of lamp body enclosure comprehensively, be conducive to the discharge of light fixture heat, thereby effectively raise the heat conduction efficiency of LED light source.Meanwhile, the fixing base of the circular elongated slot body in the cavity volume of shell has played good thermolysis.Therefore, can avoid adopting the heat radiation of fin shape in prior art, because of the defect that after long-term use, dust stratification dirt causes radiating effect to decline.Realize high-power LED light source 55 ° of safe working temperatures that C is upper and lower, ensured that the brightness of light source reaches the highest, light decay is minimum.

2. adopt the universal architecture design that can be used for road and tunnel, to expand its versatility.

Detailed description of the invention

Now with detailed description of the invention, the utility model is further illustrated by reference to the accompanying drawings.

Embodiment 1:

Consult shown in Fig. 1, Fig. 2 and Fig. 3, the utility model discloses a kind of LED lamp, comprise: the cuboid that hard metal is made or the shell 1 of similar cuboid, be arranged at the plural LEDs 2 on shell 1, be fixed on shell 1 and be positioned at the diffuser 7 of LED2 top.On 6 side panels of described shell 1, all offer passage 11, in the cavity volume of described shell 1, be provided with and connect the heating column 10 that the complex root hard metal of its upper panel 101 and downside panel 102 is made, in the cavity volume of described shell 1, be provided with the fixing base 5 of 2 semicircle elongated slot bodies formations that are individually fixed in its upper panel 101 and downside panel 102, described fixing base 5 is laterally between the Left-Hand Panel 103 and right panel 104 of shell 1.2 described semicircle elongated slot bodies are sealed and form the fixing base 5 of circular elongated slot body by bolt 6.Preferably, described hard metal is aluminium.Described heating column 10 is 20.Heating column 10 in the cavity volume of shell 1 is connected and forms stack effect and produces that (so-called stack effect refers to that air, along having the space of vertical bank to rising or decline, causes air to add the phenomenon of strong convection in the space in.), and there is cross-ventilated passage 11 all around, upper and lower several sides, strengthened the circulation of air of lamp body shell 1 inside comprehensively, is conducive to the discharge of light fixture heat, thereby effectively raises the heat conduction efficiency of LED light source.
