Abstract

The utility model relates to the road lighting lamp field, especially to high power street lamps adopting LED as the light source. The LED street lamp in the utility model comprises a street lamp rod connected with a street lamp base and a lighting lamp connected with the rod upper end. The lighting lamp is composed of a lampshade, a heat conducting silica gel layer, a LED base plate, a diaphanous panel and a plurality of LEDs, wherein the inner surface of the lampshade is debossed and the external surface of the lampshade comprises a plurality of heat radiation fins metal casing members. The heat conducting silica gel layer is equipped between the lampshade and the LED base plate to make the LED base plate bonded to and fixed on the inner surface of the lampshade. The LEDs are uniformly disposed on the LED base plate. The diaphanous panel is covered on the opening of the lampshade and forms an enclosed space structure of the lighting lamp with the lampshade opening. The utility model, by transmitting the LED base plate heat to the metal lampshade integrated to the radiating fins through the heat conducting silica gel layer and then to the air, can effectively solve the heat dissipation problem and significantly prolong the service life of the LED street lamp.

Description

A kind of LED street lamp

Technical field

The utility model relates to the road illuminating lamp field, and relating in particular to and adopting LED is the large power road lamp of light source.

Background technology

Along with the development of urban construction, road construction is perfect day by day, and illuminating street lamp shared proportion in the city illumination system is increasing, and is simultaneously also outstanding all the more with the contradiction of power shortage, and it is just more urgent to adopt new illuminating street lamp to replace having now the requirement of street lamp.And there is very big advantage in LED as a kind of new lighting engineering, and it has advantages such as long working life, luminous efficiency height, power saving.But its luminescence mechanism has determined that the power of LED can not be very high.Therefore, the application of LED street lamp substantially all is a plurality of LED that distribute on a LED substrate, thereby the illumination that realizes higher-wattage needs.Yet the heat problem that a plurality of LED produce can not be ignored.Therefore, in order to improve the service life of LED street lamp, need to solve the heating problem of LED substrate.

The utility model content

At the problems referred to above, the utility model proposes a kind of LED street lamp that can solve LED substrate heating problem effectively.

The technical solution of the utility model is:

LED street lamp of the present utility model comprises the street lamp body of rod that is connected on the street lamp pedestal and is connected in the lighting of body of rod upper end.Described lighting is made up of a lampshade, a thermal conductive silicon glue-line, a LED substrate, a light penetrating panel and a plurality of LED.Wherein, described lampshade is that inner surface is a umbilicate type and outer surface is the metal shell member of a plurality of radiating fins, described thermal conductive silicon glue-line is arranged between lampshade and the LED substrate, the LED substrate bonding is fixed in the inner surface of lampshade, described LED evenly is arranged on the LED substrate, described light penetrating panel is covered on the opening of lampshade, forms the space structure of an airtight lighting with it.

Further, the radiating fin of described lampshade outer surface is the structure that height distributes and differs.

Further, described light penetrating panel is the crystal glass sheet.

The utility model adopts as above technical scheme, be delivered on the metal shade of flange-cooled one by the heat of heat conductive silica gel the LED substrate, diffuse in the air, can solve LED road lamp cooling problem effectively, prolong the stable service life of LED street lamp greatly.

Description of drawings

Fig. 1 is an overall schematic of the present utility model;

Fig. 2 is the generalized section of lighting of the present utility model.

The specific embodiment

Now with the specific embodiment the utility model is further specified in conjunction with the accompanying drawings.

Consult illustrated in figures 1 and 2ly, LED street lamp of the present utility model comprises the street lamp body of rod 2 that is connected on the street lamp pedestal 1 and is connected in the lighting 3 of the body of rod 2 upper ends.Described lighting 3 is made up of a lampshade 31, a thermal conductive silicon glue-line 32, a LED substrate 33, a light penetrating panel 35 and a plurality of LED34.Wherein, described lampshade 31 is that inner surface is a umbilicate type and outer surface is the metal shell member of a plurality of radiating fins, described thermal conductive silicon glue-line 32 is arranged between lampshade 31 and the LED substrate 33, LED substrate 33 bondings are fixed in the inner surface of lampshade 31, described LED34 evenly is arranged on the LED substrate 33, described light penetrating panel 35 is covered on the opening of lampshade 31, forms the space structure of an airtight lighting with it.

Preferably, the radiating fin of described lampshade 31 outer surfaces is structures that height distributes and differs.The radiating fin of the structure that the height distribution differs more helps hot gas flow, accelerates air the heat on the lampshade 31 is taken away, and is beneficial to cooling.

Preferably, described light penetrating panel 35 is crystal glass sheets.Like this, LED street lamp light transmittance of the present utility model is higher, and light penetrating panel 35 surfaces more are difficult for being scratched, and the long-term back light transmittance that uses still can keep stable.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present utility model that do not break away from appended claims and limited; can make various variations to the utility model in the form and details, be protection domain of the present utility model.
