Abstract

The utility model discloses a street lamp structure consisting a lampshade, a light source, an outer shell and a power supply; wherein, a heat conducting device is arranged between the light source and the outer shell; the outer shell of the street lamp structure is a heat radiator exposed in the air with relatively big surface area having good radiating effect. The setting of the heat conducting device between the light source and the outer shell makes use of a conducting principle to directly connect the heat energy generated by the light source onto the outer shell with big radiating area and good radiating effect. The heat energy is radiated into the air by virtue of cross-ventilation. The utility model adopts the open type heat radiator to radiate high thermal energy into the air by cross-ventilation, and is safe and beautiful. Apart from keeping the airtight need of street lamp, the utility model can improve the illuminating brightness and prolong the service life.

Description

A kind of lamp post structure

Technical field

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

Background technology

Present employed street lamp, about 14 meters of main road lamp, about 8 meters of subsidiary road lamp for asking highlight illumination, needs consumption high-power, so that produces high heat energy.And street lamp itself need place confined space with light source based on the requirement that prevents aqueous vapor, dust fall, as does not have good cooling system, certainly will influence its luminosity and service life.

The utility model content

The purpose of this utility model provides a kind of lamp post structure, and it has the open type heat abstractor, can maximum area contact with air, and the heat energy with light emitting source produces distributes in air fast.

For achieving the above object, solution of the present utility model is: a kind of lamp post structure, comprise Transparent lamp shade, light source, shell and power supply, and wherein between light source and shell, be provided with heat-transfer device.

Described heat-transfer device is heat conduction facilities such as heat-conducting cream (or glue), heat-conducting metal (as aluminium, copper or its alloy) or heat pipe.

Described light source comprises various light sources such as incandescent lamp, fluorescent lamp, high-pressure mercury lamp, Halogen lamp LED or LED.

Described power supply can be solar cell, the time process control energy-saving electric power or other kind power supply.

After adopting such scheme, because to be a surface area big and expose to the heat abstractor of the excellent in heat dissipation effect that forms in the air for the shell in this lamp post structure, and the setting of heat-transfer device between light source wherein and the shell, it is big that the heat energy that utilizes conduction principle directly light source to be produced in time is connected in area of dissipation rapidly, on the shell of excellent in heat dissipation effect, heat energy is launched in air by cross-ventilation.Adopt the open type heat abstractor, high heat energy is launched in air by cross-ventilation, either safety but also attractive in appearance, except that can keeping the airtight requirement of street lamp, or can improve its luminosity, its service life prolonged.

The specific embodiment

As shown in Figure 1, 2, lamp post structure of the present utility model, it comprises Transparent lamp shade 1, shell 2, light source 3, heat-transfer device 4 and power supply (not shown), power supply can be solar cell, the time process control energy-saving electric power or other kind power supply.

Transparent lamp shade 1 forms confined space with shell 2, and light source 3 is to place in this confined space, most critical is: be provided with the heat-transfer device 4 that is connected the two between light source 3 and shell 2, this heat-transfer device 4 can be heat conduction facilities such as heat-conducting cream (or glue), heat-conducting metal (as aluminium, copper or its alloy) or heat pipe; And shell 2 to be surface areas big and expose to the heat abstractor of the excellent in heat dissipation effect that forms in the air, it can be lampshade, lamp housing, light fixture or metal shells such as support, pillar; Light source 3 comprises various light sources such as incandescent lamp, fluorescent lamp, high-pressure mercury lamp, Halogen lamp LED or LED.Setting because of this heat-transfer device 4 can make the high heat energy of light source 3 generations can be sent on the shell 2 rapidly just, can further be provided with radiating fin 21 on the shell 2 to increase the surface area of its heat radiation, utilize conduction principle directly the heat energy that light source 3 produces to be launched heat energy in air by cross-ventilation.

As shown in Figure 3, further be provided with reflector 5 on the sidewall in Transparent lamp shade 1,, shine downwards through Transparent lamp shade 1 with the effect of throwing after this collected light, the heat energy that is produced is directly connected on the shell 2 via heat-transfer device 4, via cross-ventilation high heat energy is distributed in air.

As shown in Figure 4, it is an indirect daylighting street lamp, device reflecting plate 6 above road lamp cap, and these reflecting plate 6 double heat sink effects, light shines back reflections to ground by the lamp holder light source to reflecting plate 6, can increase the soften and the lighting area of light.

To sum up, the utility model is to adopt the open type heat abstractor, setting by inner heat-transfer device, the high heat energy that can make light source produce is launched high heat energy in air by cross-ventilation, not only safe but also attractive in appearance, except that can keeping the airtight requirement of street lamp, more can improve its luminosity, prolong its service life.The utility model can be used for lightings such as outdoor street lamp, flower garden lamp, also can be used in lightings such as indoor corridor lamp, aisle lamp.
