Description

High-power LED street lamp

Technical field

The utility model relates to a kind of street lamp, especially relates to a kind of high-power LED street lamp.

Background technology

Street lamp is the important component part of city illumination, and traditional street lamp adopts high-pressure mercury lamp usually.The required power of high-pressure mercury lamp is big, and power consumption is high; High-pressure mercury lamp 360 degree are luminous, and light loss is big, and the instream factor of the energy is not high; And temperature is too high during work, causes the service life of light source not long.Need often to change street lamp, cause certain waste.

Current, global environment is going from bad to worse, and each state is all at the development clean energy resource.And along with the rapid growth of national economy, China's energy supply and demand contradiction is outstanding day by day, the coming into existence situation of critical shortage of supply of electric power, and energy-conservation is present institute urgent problem.Therefore, the LED street lamp arises at the historic moment.

But traditional LED street lamp generally is that the LED lamp is located on the substrate, and substrate directly is welded on the lamp housing; The heat that a plurality of LED lamps produce is very high, can not be ignored.But the degree of heat radiation of lamp housing is not high, and the heat absorption that can not be at short notice a plurality of LED be produced also leaves, and causes shorten the service life of this LED street lamp.

Summary of the invention

Therefore, to above-mentioned problem, the utility model provides a kind of energy-conserving and environment-protective, thermal diffusivity is good, service life is relative to long high-power LED street lamp.

For achieving the above object, the utility model is realized through following technical scheme: a kind of high-power LED street lamp comprises shell, several heat conduction bars, LED lamp group, holder and power supply; The upper surface of said shell is provided with several air vents, and the shell lower surface is provided with and the corresponding air vent of upper surface, and the heat conduction bar is embedded in each air vent; LED lamp group comprises substrate, be located at several LED on the substrate and be located at the lens of LED top; The quantity of LED lamp group is corresponding with the heat conduction bar, and substrate is located at the lower surface of each heat conduction bar respectively, and lens are fixedly arranged on the shell; Holder is located on the shell, and LED lamp group is electrically connected with the output of power supply.

Further improve and be: the height of said heat conduction bar is greater than the height of shell.

Through adopting the aforementioned techniques scheme, the beneficial effect of the utility model is: the heat that LED produces, be delivered on the heat conduction bar, and the heat conduction bar is embedded on the shell, transmits a part of heat and gives shell.Heat conduction bar and shell have absorbed the heat that most of LED produces, and shell is provided with air vent, can heat be left fast.Make the radiating effect of high-power LED street lamp of the utility model be improved, prolonged the service time of street lamp.And the more energy saving of high-pressure mercury lamp that the LED contrast is traditional.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

Embodiment:

With reference to figure 1, Fig. 2 and Fig. 3, present embodiment discloses a kind of high-power LED street lamp, comprises shell 1, heat conduction bar 2, LED lamp group, holder 3 and power supply 4, wherein:

The upper surface 11 of said shell 1 is provided with several air vents; Shell 1 lower surface 12 is provided with and upper surface 11 corresponding air vents; The shape of heat conduction bar 2 is corresponding with air vent; Said heat conduction bar 2 is embedded in each air vent, and the height of heat conduction bar 2 is greater than the height of shell 1, and the part that heat conduction bar 2 exceeds shell 1 is more conducive to heat radiation.2 minutes 2 rows of heat conduction bar, 5 of every rows, totally 10.

LED lamp group comprises substrate 51, be located at 5 LED52 and lens 53 on the substrate 51, and substrate 51 is located at the lower surface of each heat conduction bar 2 respectively, and lens 53 are located at the LED52 top and are fixedly arranged on the shell 1.The quantity of LED lamp group is corresponding with the quantity of heat conduction bar 2.

Holder 3 is located on the shell 1, is used for the utility model is fixed in electric pole.LED lamp group is electrically connected with the output of power supply 4 through water proof wire, and power supply 4 can be hidden according to actual needs in electric pole or is located on the shell 1.

The heat that LED produces is delivered on the heat conduction bar, and the heat conduction bar is embedded on the shell, transmits a part of heat and gives shell.Heat conduction bar and shell have absorbed the heat that most of LED produces, and shell is provided with air vent, can heat be left fast.Make the radiating effect of high-power LED street lamp of the utility model be improved, prolonged the service time of street lamp.And the more energy saving of street lamp that contrast such as LED is traditional.

Preferably, present embodiment adopts 10 heat conduction bars, and each substrate is provided with 5 LED, but its number can be set up or reduces according to actual production; The position of power supply can be hidden in electric pole, also can be located on the shell, can also realize the technical purpose of present embodiment.

The above record is merely the embodiment that utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
