Abstract

The utility model discloses a heat-insulating LED street lamp. The heat-insulating LED street lamp is divided into an upper cavity and a lower cavity by a reflecting shield that is coated with heat-insulating material on the surface, one or more LED lamps are arranged on the bottom surface and the inclined surface of a radiating base that is arranged in the lower cavity, one or more heat tubes are embedded into the radiating base, the heat emitting end of the heat tube is fixed on a lamp cap base and extends out of the upper cavity, and radiating fins are arranged on the heat emitting end. The heat-insulating LED street lamp adopts the technique that LED heat is conducted to the upper cavity and heat recursion to the lower cavity, in which the LED is positioned, is avoided, thus having good radiating performance, effectively guaranteeing LED radiation and environmental temperature stability, and prolonging the service life of the LED. Position of the LED light source is almost the same with the position of traditional light sources in the reflecting shield, thus preventing the generation of LED glare. The angle of LED lights can be adjusted by the trapezoidal angle of the radiating base so as to satisfy the requirements of different ground illumination intensity. The heat-insulating LED street lamp has convenient installation, easy access to traditional street lamps, lower development cost and product price.

Description

Heat insulation type LED street lamp

Technical field

The utility model relates to lighting field, relates in particular to a kind of high-power LED street lamp.

Background technology

The characteristics that the LED lighting tool has that colourity is good, non-maintaining, the life-span is long, in the energy more and more nervous today, the LED street lamp replaces city large electricity consumer's conventional road lamp illumination, is the inexorable trend of future development.But because technical reason, the LED caloric value is big, and heating is having a strong impact on light decay and the life-span of LED, so the applying of LED, heat radiation is the key technology that must resolve, is restricting the development of LED.Make a general survey of LED street lamp on the market, with die sinking again, lamp housing is many as the mode of LED radiator, though this light fixture modern design, development cost and product price are all than higher, also has dazzle when doing road lighting, influence driver's sight line, and the weight ratio conventional lamp is big, on the lamp stand structure, needs redesign, and do not make full use of existing traditional road lighting market resource, cause the waste of social resources.

The utility model content

Technical problem to be solved in the utility model is exactly at above-mentioned deficiency, and a kind of perfect heat-dissipating is provided, can utilize existing road illumination resource to be common to the conventional road lamp light fixture, the high-power LED street lamp of being convenient to install, price is low, satisfies the needs of the high-power LED illumination of street lamp.

The purpose of this utility model can be achieved through the following technical solutions:

Light fixture is divided into upper cavity and lower chamber by the reflection shield that the surface scribbles heat-barrier material, the bottom surface and the inclined-plane of the heat dissipation base in the lower chamber are equipped with one or more LED lamps, embedded one or more heat pipe of heat dissipation base, the heat pipe release end of heat that is fixed on the bulb socket stretches out upper cavity and the heat radiation wing is housed.

At least one heat pipe is connected two parts space that is divided into by heat-barrier material with bulb socket.

The profile of heat dissipation base is prismatoid or hexagonal prism.

The reflection shield outer surface scribbles insulating moulding coating or adopts heat-barrier material to make.

Compared with prior art, what the utility model adopted conducts to upper cavity to the LED heat, and does not allow heat pass back to the technology of LED lower chamber of living in, its perfect heat-dissipating, and stablizing of the heat radiation of strong guarantee LED and environment temperature prolonged the life-span of LED.Led light source present position and conventional light source present position in reflection shield has prevented the generation of LED dazzle much at one.The angle of LED light can be adjusted by the heat dissipation base trapezoidal angle, satisfies the requirement of Different Ground illumination.Be convenient to install, easy and conventional road lamp tool is plugged into, and development cost and product price are all lower.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Typical structure of the present utility model is seen Fig. 1, Fig. 2, shown in Figure 3, heat insulation type LED street lamp, and light fixture 8 is divided into lower chamber 10 and upper cavity 11 two parts by reflection shield 4.Two cavitys only carry out heat transmission by heat pipe.Heat dissipation base 1 is a prismatoid, at least one LED lamp 2 is equipped with in the bottom surface, the heating end of at least one heat pipe 3 is embedded in the heat dissipation base 1, and support 12 and liner plate 13 are fixed on heat pipe 3 on the bulb socket 5 by bolt, and the release end of heat that heat radiation wing 6 is housed is bent upwards about 30 °.Reflection shield 4 outer surfaces scribble barrier insulating moulding coating 9, and perhaps reflection shield 4 uses heat-barrier material to make, and stop that the heat of heat radiation wing 6 releases is transmitted to the lower chamber 10 at LED lamp 2 places by reflection shield 4.

Heat pipe 3 is a kind of heat transfer elements with high heat conductivility, and the heat that LED lamp 2 produces can discharge by heat pipe 3 and heat radiation wing 6 fast.The LED heat can not conducted back inner chamber body after being transmitted to outer chamber from inner chamber body.Heat insulation type LED street lamp is characterized in that: can adjust the angle of LED light by changing the shape of heat dissipation base.

Heat dissipation base 1 is a prism, and the LED lamp 2 that is contained in the inclined-plane can be adjusted LED lamp 2 radiation directions by heat dissipation base 1 bevel angle.

Heat dissipation base 1 is divided into two parts up and down, and heat pipe 3 is installed in heat dissipation base 1 inside by bolt.Fig. 4 is the another kind of version of heat dissipation base 1, and profile is a hexagonal prism, all LED lamp 2 can be installed for five.

The release end of heat of heat pipe 3 is bent upwards 30 °, helps heat and discharges fast.

In order to make full use of existing street lamp resource, bulb socket 5 and reflection shield 4 all can be on the basis of conventional road lamp lamp fittings process and remould.

Though the utility model only illustrates and describes by embodiment; but those skilled in the art should understand; in the scope of claims; the form of the installation of opposite heat tube 3, quantity; the different modes that reflection shield 4 is heat insulation; heat dissipation base 1 profile multi-form all belongs to protection domain of the present utility model.
