Description

Intelligent semiconductor energy saving street lamp with long life

Affiliated field

The utility model relates to a kind of intelligent semiconductor energy saving street lamp with long life, belongs to the road lighting device, is used for road lighting.

Background technology

The present street lamp that uses, its light source generally adopts metal sodium vapor lamp or high pressure tribute lamp, and these several light source power consumptions are big, and general single light source power bracket is at 100W to 400W, and power is higher during specific (special) requirements; Because light source adopts glass-encapsulated, and is fragile, the life-span is short, and average life span was at 5000 hours, and the maintenance cost height; Moreover, contain mercury or halide etc. in the light source, damage the back and can pollute, and can not reclaim environment.

LED is widely used in the Landscape Lighting as novel solid cold light source, and along with the appearance of improving constantly of led chip power and light efficiency, particularly large power white light LED, LED is used for illumination has become possibility.According to scholarly forecast, all use LED instead as light source if will have street lamp now, can save one three chivalrous power station annual electricity generating capacity every year, can effectively alleviate the power tense situation of China; And the led light source life-span reaches 100000 hours, and is non-maintaining, can save a large amount of maintenance costs; If adopt solar cell to provide the energy, just can save more electric energy, and can effectively utilize solar energy for the street lamp led light source.

At present, existing LED street lamp mainly adopts the LED connection in series-parallel of many low luminous efficiencies to form, complex circuit, and luminous flux is low, can not satisfy the needs of illumination.

Summary of the invention

The purpose of this utility model is a kind of intelligent semiconductor energy saving street lamp with long life that designs at above-mentioned phenomenon, it has the luminous flux height, energy-saving effect is better, the life-span is long, good heat dissipation, non-maintaining, automatic time switch lamp, advantages such as led light source group are lighted in grouping at times automatically, and alternative existing street lamp is used for road lighting.

The purpose of this utility model is achieved in that and adopts large power white light LED as road-light light-source, LED, forms luminescence unit with the fin of LED coupling and with the transparent light guide cover that fin bonds together; Luminescence unit divides three groups laterally to be installed in one and to be fixed on aluminium alloy lamp housing inside, has on the aluminium alloy heat sink of via hole and installing hole and electroplate, constitutes semiconductor luminous assembly.Smear the good silicone grease of one deck heat conduction between fin in each luminescence unit and the aluminium alloy heat sink, this aluminium alloy heat sink has reflective and heat sinking function; The single power of first, second and third group LED is respectively 1W, 3W, 1W, and every group of LED is connected in parallel, and its quantity is decided according to watt level; Controlling three groups of LED by the intelligent controller that is installed in the lamp stand bottom divides into groups to light automatically at times, to reach bright entirely to three groups of LED of 0:00 in darkness, second group of 0:00 to 3:00 is bright, 3:00 lights wherein two groups of LED to daybreak, like this, and both can be for a long time the darkness pedestrian, street lamp has enough brightness, also consider pedestrian's visibility on road surface after a little while, thereby, reach more energy-conservation effect.

The utility model adopts great power LED as light source, and has adopted the transparent light guide cover, has improved luminous efficiency, and is simultaneously simple in structure, easy for installation; Light owing to adopted intelligent controller to control three groups of LED timesharing groupings, thereby make this semiconductor road lamp more energy-conservation; Owing to adopted the aluminium alloy structure design, make this road lamp cap radiating effect better, prolonged service life, therefore, the utility model can substitute existing street lamp, is used for road lighting.
