The street lamp comprises a hermetic upper casing, a lower transparent cover and at least three linked LED lamps in the lower transparent. The upper casing is made of heat conductivity materials, a radiating flange is equipped integrally on the outer side at the upper portion of the upper casing, an inner plane is provided on the inner wall of the upper casing corresponding to the radiating flange, a lamp socket is fixed on the inner plane, an insulating heat outlet washer is arranged between the inner plain and the lamp socket, two ranking elasticity conductive inserters are equipped in the lamp socket, the ranking LED lamps are plugged in the lamp socket, the positive pole and the negative pole of the LED lamp are contacted respectively with the two conductive inserters, a portion of the each conductive inserter extends the lamp socket and is contacted with the insulating heat outlet washer, and the power of the street lamp supplies electricity to the conductive inserters. The normal usage of the LED street lamp can not be affected as the heat dissipation problem.

Description

The LED street lamp
Technical field
The utility model relates to lighting technical field, especially a kind of LED street lamp.
Background technology
Road lighting lamp is the lamp that China service time is the longest and power consumption is maximum, and the power of every street lamp is 150W-400W, and in the face of electric power energy is in short supply, country vigorously advocates environmental protection and energy saving.There is developed country at first to use LED (light emitting diode) street lamp at present, the theoretical life-span of LED street lamp can reach 100,000 hours, power consumption under the similar illumination but has only 10% of incandescent lamp, replace the plain and halogen street lamp of all traditional sodium with the LED street lamp, trend will be inevitable, but existing LED street lamp is because when using being arranged in a combination of a plurality of LED, its heat dissipation problem of solution that can not be good, the little fashion of LED lamp power can normally be used, when LED lamp power is big, the heat that the LED lamp sends can not well distribute, and causes the damage of LED lamp to be scrapped, and influences people's normal use.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of new LED street lamp is provided, has better heat radiating effect, overcome the deficiency that existing LED street lamp power can not normally use because of heat dissipation problem when big.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED street lamp, have airtight upper casing and following translucent cover and at least three built-in LED lamps that link to each other, described upper casing is made by Heat Conduction Material, the upper casing upper outside has been wholely set fin, has an inner plane with fin corresponding position inwall on the upper casing, fixed lamp-socket on the inner plane, also be provided with the insulating heat-conductive pad between inner plane and the lamp socket, be provided with the elastic conduction plug-in unit of arrangement in the lamp socket, the LED lamp of arranging is inserted on the lamp socket, the LED lamp just, negative pole respectively with two conducting plug Elastic Contact, conducting plug have the lamp socket of stretching out and with the contacted part of insulating heat-conductive pad, the power supply of street lamp is powered to conducting plug.
Furtherly: described elastic conduction plug-in unit is that copper spare, cross sectional shape are W shape.
Furtherly: described lamp socket has partitioned organization, and the LED lamp of arranging on each lamp socket is 6 of 11 rows, every rows, and 6 LED lamps of every row are the series connection form, adopt parallel form between every row; More specifically say: the single led light working voltage that is adopted is 3.2 volts, and operating current is 80 milliamperes.
Furtherly: described upper casing is an aluminum casting.
The beneficial effects of the utility model are, LED street lamp of the present utility model has mainly been taked following measure at the heat dissipation problem to the LED lamp: one, fin and upper casing are structure as a whole, and fin is positioned at the outside of upper casing, good heat dissipation effect; Two, the elastic conduction plug-in unit that connects power supply is set on lamp socket, LED directly is inserted on the lamp socket, no solder joint, and the heat that self produces during energising is little; Three, the insulating heat-conductive pad is set between lamp socket and upper casing, and makes direct soft contact of conducting plug and insulating heat-conductive pad, more help the heat transmission of lamp is distributed.Above-mentioned measure makes the bigger LED street lamp of power can not influence normal use because of heat dissipation problem.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, upper casing, 2, translucent cover down, 3, the LED lamp, 4, lamp socket, 5, the insulating heat-conductive pad, 6, conducting plug, 11, fin.
The specific embodiment
A kind of specific constructive form of the utility model LED street lamp as shown in Figure 1, have airtight upper casing 1 and following translucent cover 2 and at least three built-in LED lamps 3 that link to each other, upper casing 1 is made by Heat Conduction Material aluminium, upper casing 1 upper outside has been wholely set fin 11, has an inner plane with fin 11 corresponding position inwalls on the upper casing 1, fixed lamp-socket 4 on the inner plane, also be provided with insulating heat-conductive pad 5 between inner plane and the lamp socket 4, be provided with the elastic conduction plug-in unit 6 of arrangement in the lamp socket 4, the LED lamp of arranging is inserted on the lamp socket 4, the LED lamp just, negative pole respectively with two conducting plug 6 Elastic Contact, conducting plug 6 have the lamp socket of stretching out 4 and with insulating heat-conductive pad 5 contacted parts, the power supply of street lamp is powered to conducting plug, elastic conduction plug-in unit 6 is a copper spare as shown in the figure, cross sectional shape is a W shape, W shape conducting plug 6 is stuck on the skeleton of lamp socket 4, and position corresponding with the elastic foot of W shape both sides on lamp socket 4 is provided with the LED lamp foot jack.
The lamp socket 4 of this concrete mode adopts partitioned organization, and the LED lamp of arranging on each lamp socket 43 is 6 of 11 rows, every rows, and 6 LED lamps of every row are the series connection form, adopt parallel form between every row.
