Abstract

The utility model discloses an outdoor lighting device that is connected with a circumscribed power supply or an internal power supply, which consists of an open type metal base and an illuminant. The illuminant is arranged in the base and the radiating fins are uniformly distributed around the circumference of the base; and a heating conducting device is arranged between the illuminant and the circumference of the base. As the illuminant is arranged in the open type metal base, the heat energy generated by illuminant can emitted to the open space; in addition, the radiating fins around the circumference of the base can increasing the radiating area of the base and further enhance the radiating effect; furthermore, the heat conducting device can rapidly conduct the more intensive heat in the middle of the base to the circumference of the base and emit the heat to the air with the help of the radiating fins, thereby guaranteeing the service life of the whole lighting device.

Description

The outdoor lighting device

Technical field

The utility model is about a kind of lighting device, is meant a kind of outdoor lighting device especially.

Background technology

Present employed tunnel illuminating lamp for asking highlight illumination, needs consumption high-power, thereby can produce high heat energy.And based on the requirement that prevents dust fall, light source need be placed confined space, as not have good cooling system, will certainly influence its luminosity and service life.

The utility model content

The purpose of this utility model is to provide a kind of brightness height, service life good outdoor lighting device.

For achieving the above object, solution of the present utility model is: a kind of outdoor lighting device connects and establishes external power supply or built-in power; It is made of an open type metab and illuminator, and illuminator is fixedly arranged in the base, and is evenly distributed with radiating fin at the base periphery, is provided with heat-transfer device between illuminator and the base periphery in addition.

Described radiating fin is to be vertically to be arranged in the base periphery.

Described illuminator is a plurality of illuminators, and is uniformly distributed in the base.

Described illuminator is light emitting diode (LED).

Described heat-transfer device is heat-conducting cream, heat-conducting metal or heat pipe.

After adopting such scheme,, cooperate the setting of radiating fin and heat-transfer device again, can make it have following advantage because outdoor lighting device of the present utility model is provided with the metab of open type, and has a plurality of illuminators:

1, brightness height, because the setting that traditional relatively single illuminator is set of a plurality of illuminators, its brightness can increase fully to satisfy the requirement of tunnel illumination or outdoor other illumination.

2, heat radiation is good, because illuminator is arranged in the metab of open type, then the heat energy of illuminator generation can distribute by this space of opening wide; The radiating fin of base periphery can increase the area of dissipation of base in addition, further improves radiating effect; Moreover the setting of heat-transfer device, the heat that base middle part heat energy comparatively can be concentrated guarantees the service life of whole light-emitting device by this heat-transfer device guide seats periphery and cooperate radiating fin and heat energy is distributed in air rapidly with this.

3, easy to clean because the radiating fin of base periphery is to be vertically to arrange, and the dust of air is difficult for piling up, with the radiating effect that guarantees that it is preferable, simultaneously this be provided with longitudinally can easy cleaning.

In a word, the setting of its said structure of outdoor lighting device of the present utility model, can maximum area contact with air, the heat energy that illuminator is produced distributes in air fast simultaneously, thereby has brightness height, long effect of life-span.

The specific embodiment

As shown in Figure 1, 2, outdoor lighting device of the present utility model connects and establishes external power supply or built-in power; It comprises a metab 1, illuminator 2 and heat-transfer device 3;

This metab 1 is the base of an open type, and its bottom sets firmly illuminator 2, and this illuminator 2 can adopt the high light-emittingdiode of a plurality of brightness (LED), and these a plurality of illuminators 2 are distributed in the base 1 uniformly; And the periphery of base 1 is and vertically is evenly distributed with radiating fin 11; Be provided with the heat-transfer device 3 that connects illuminator 2 and base periphery in addition in base 1 bottom, this heat-transfer device is heat-conducting cream (glue), heat-conducting metal (as good metals of heat-conducting effect such as copper, aluminium or its alloys) or heat pipe.

Because metab 1 is the design of open type, the high heat energy that can make illuminator 2 produce distributes in air; The radiating fin 11 of base 1 periphery can increase the area of dissipation of base 1 in addition, further improves radiating effect; Moreover the setting of heat-transfer device 3, the heat that base 1 middle part heat energy comparatively can be concentrated guarantees the service life of whole light-emitting device by this heat-transfer device 3 guide seats 1 periphery and cooperate radiating fin 11 and heat energy is distributed in air rapidly with this.And the setting that traditional relatively single illuminator is set of a plurality of illuminators 2, its brightness can increase fully to satisfy the requirement of tunnel illumination or outdoor other illumination.Radiating fin 11 is to be vertically to arrange, and the dust of air be difficult for to be piled up, with the radiating effect that guarantees that it is preferable, simultaneously this be provided with longitudinally can easy cleaning.
