Description

Colourfully decorated lantern among the LED

Technical field

The utility model relates to a kind of lighting, refers to a kind of colourfully decorated lantern among the outdoor LED that is applied to especially.

Background technology

In colourfully decorated lantern be historical product, appearance is bright and new, and is dignified, solemnly be the true qualities of middle colourfully decorated lantern.Its outward appearance is generous, and a plurality of illuminators are generally arranged, and is generous proper, the illuminance height, and landscape effect is good, is a kind of street lamp with China's characteristic.It is applicable to outdoor street lighting engineerings such as municipal works, gardens lighting engineering and power office, development zone, villa district, square.

A plurality of illuminators of colourfully decorated lantern adopt tungsten filament as light emitting source usually in the tradition, because the luminous of tungsten filament is comprehensive property (non-directive), so can't export more light source to specific direction, but it is big as the illuminator consumed power of light emitting source with tungsten filament, the illumination that the power of every watt of consumption can provide is suitable poor at last in the middle of present light emitting source, particularly colourfully decorated lantern all has a plurality of illuminators in each small cup, therefore its consumed power is big well imagines, though the consumed power of colourfully decorated lantern is very big in the tradition, but its intensity of illumination that provides is very little, light efficiency is poor, and energy waste rate height and light pollution are serious; Simultaneously because life-span of tungsten filament is shorter, with tungsten filament as in the light emitting source of colourfully decorated lantern also can cause in the often replacing of light emitting source needs of colourfully decorated lantern, cause the maintenance cost increase, problems such as maintenance difficulties enhancing.

Light emitting diode (Light-Emitting Diode, LED) belong to semiconductor subassembly, principle of luminosity is to convert electrical energy into luminous energy, because the life-span of LED reached more than 100,000 hours, and advantages such as LED has, and reaction speed is fast, volume is little, power saving, low pollution, high-reliability, suitable volume production are so become the nova of illumination market soon.

Demand along with energy conservation and environmental protection, utilize LED to come to provide in the construction people daily life light fixture of illumination to become world trend, in present technology, LED can be installed on the various carrier (for example printed circuit board (PCB)) usually, make lighting unit; Yet LED can produce a large amount of heat energy simultaneously when producing light source, and therefore in above-mentioned lighting unit, the heat energy that LED produces often can't be arranged effectively and be dissipated to outside the device, thereby causes the luminous efficacy of LED to reduce; If the efficient of the radiator structure of LED lighting unit is not good, will make LED produce light decay or look change, allow the life-span of LED significantly reduce; Therefore the reliability that the radiating efficiency that how to increase the LED lighting unit improves use has become an important techniques problem.

The utility model content

Problems such as the purpose of this utility model is to provide colourfully decorated lantern among a kind of LED that can effectively reduce the heat energy that the LED lighting unit produces when luminous, and is big to improve in the tradition colourfully decorated lantern consumed power greatly, and light efficiency is low, and light pollution is serious, and the energy waste rate is high and difficult in maintenance.

In order to reach above-mentioned purpose, solution of the present utility model is:

Colourfully decorated lantern among a kind of LED comprises lamppost, a plurality of lighting unit and is located at the lamppost top in order to install the lamp holder of lighting unit that each LED lighting unit comprises support bar, base, driving power, cooling system, LED module and outer cover; One end of support bar is located on the lamp holder, the bottom that the other end is connected with base, the other end of base connects cooling system, the top of cooling system is connected with outer cover, driving power is located in the cooling system, the LED module is located at the top of cooling system and is placed in the outer cover, and this LED module is electrically connected with driving power.

Described cooling system is a cone shape hollow structure, comprises skin, inwall and hollow bulb, and outer uniform ring is provided with fin, the ccontaining described driving power of hollow bulb.

Colourfully decorated lantern also comprises a diffusion diffuser among this LED, and this diffusion diffuser is located in the outer cover and is covered at LED module top.

Be provided with sealing ring between described cooling system and the base, be provided with sealing ring between cooling system and the outer cover.

The inwall of described cooling system adopts aluminum alloy materials to make.

After adopting said structure, colourfully decorated lantern among the utility model LED is owing to adopt the LED module as light emitting source, and LED has advantages such as long, the high and low radiation of light efficiency of life-span and low-power consumption, high-reliability, low pollution, and it can improve greatly, and the colourfully decorated lantern consumed power is big in the tradition, light efficiency is low, light pollution is serious, the senior problem such as difficult in maintenance of energy waste rate.When colourfully decorated lantern is worked among the utility model LED, LED module among this LED in each LED lighting unit of colourfully decorated lantern is luminous, and while distribute heat, these heats can conduct to fin by the inwall of cooling system, heat is spread in the form of a ring, and the heat that the LED module is produced distributes fast, thereby reduces the operating temperature of LED module, promote the luminous efficiency of LED module, prolong the service life of LED illuminating module.And then improve colourfully decorated lantern A among the utility model LED luminous efficiency, prolong colourfully decorated lantern among this LED service time to reduce maintenance frequency, reduce human and material resources, financial resources expenditure.
