Description

A kind of LED street lamp with heat pipe

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 LED street lamp of existing direct heat dissipation type is to utilize fin that the heat of LED substrate is transmitted to ambient air, and such heat radiation is lentamente, and efficient is not high.Perhaps, the LED street lamp of existing band fan heat radiation can end influence heat radiation because of the life-span of fan, and makes a noise easily when working.

The utility model content

At the problems referred to above, the utility model proposes a kind of LED street lamp that directly utilizes heat pipe to solve LED substrate heating problem effectively.It has not only avoided the low defective of direct radiating efficiency, and has avoided street lamp when work noise big, the defective that the radiator fan life-span is short.

The technical solution of the utility model is:

The LED street lamp of band heat pipe 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, a plurality of LED and a heat pipe described lighting.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, and described heat pipe is arranged at the lampshade top.

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

Further, the circuitous lampshade (31) that is arranged at of described heat pipe is gone up in the gap of adjacent radiating fin (311).

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, and the heat pipe that is provided with by radiating fin on lampshade is passed to the heat of fin on the metal shade in the extraneous air fast and undisturbedly, can solve LED road lamp cooling problem at a high speed effectively, and avoided the short and big defective of noise of cooling system life-span, prolonged 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 vertical view of lampshade of the present utility model and heat pipe assembly relation.

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, a plurality of LED34 and a heat pipe 36 described lighting 3.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, and described heat pipe 36 is arranged at lampshade 31 tops.Preferably, described heat pipe 36 is circuitous being arranged in the gap of adjacent radiating fin 311 on the lampshade 31, is used for the heat of lampshade 31 is taken away.Wherein, the shadow shield 312 around the lampshade 31 is used to launch light, makes more all even the concentrating of light of the LED34 on the LED substrate 33.

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 and flows, and is beneficial to 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.

LED street lamp of the present utility model, be that heat with LED substrate 33 is transmitted on the radiating fin 311 of lampshade 31 by thermal conductive silicon glue-line 32, simultaneously, by being arranged at the heat pipe 36 that is provided with on the lampshade 31, the heat on the radiating fin 311 is transmitted in the extraneous air fast and undisturbedly by heat pipe 36.

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.
