Technical field
The utility model relates to a kind of LED street lamp of optimized heat radiation structure, relates in particular to a kind of LED street lamp of optimized heat radiation structure of lighting technical field.
Background technology
Street lamp is often installed on electric wire thick stick, as illuminating light fixtures such as street, highways, for people on the road in Hunan or the trip at night illumination is provided, make people's trip more convenient, safety, its demand is very big.LED street lamp is because its anti-seismic performance is good, and light efficiency is high, little power consumption, and the characteristic such as long, easy to control, non-maintaining, safety and environmental protection of life-span, is more and more subject to liking of people.LED street lamp is in the market in order to reach heat radiation object, and radiator volume is larger, and shape matching is single, larger with conventional road lamp shape difference.When replacing conventional road lamp, the whole light fixture of original street lamp must be dismantled and changed, and street lamp is because power is larger, its thermal diffusivity often affects its service life, and existing LED road lamp cooling poor effect, cost is high and do not have a diffuse effect, and the light that many LED street lamps send all can make people feel dazzling, thereby make people uncomfortable, especially for the crowd with vertigo, very easily bring inconvenience, bring great inconvenience to the people that drive, some LED street lamp, owing to adopting diffuse reflective structure, causes the light transmission of street lamp not good.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art and shortcoming, the utility model provides a kind of good heat dissipation effect, long service life and has had the LED street lamp of the optimized heat radiation structure of diffuse effect.
A kind of LED street lamp of optimized heat radiation structure comprises reflection shield, lens, rubber blanket, light source, radiator and fan, reflection shield rear portion is fixed with lens, lens rear side is provided with rubber blanket, lens outside is coated with diffuse reflection coating layer, in rubber blanket, be provided with the through hole for fixed light source, light source is spirally connected by screw and lens and light source is connected in rubber blanket inner side, light source rear side is connected with radiator, radiator rear portion is provided with fan, between light source and radiator, be provided with conducting strip, described radiator comprises substrate and radiating subassembly, substrate is provided with some groups of radiating subassemblies, radiating subassembly comprises supporter and some fin, supporter is fixed on substrate, described some fin are circumferentially spaced apart and fix with supporter along supporter, every fin extends along supporter short transverse, between adjacent fin, form heat dissipation channel.
Preferably, described fin is provided with cross-ventilation through hole.
Preferably, described conducting strip is heat radiation Copper Foil.
Preferably, described reflection shield outside is socketed with the heat dissipating housing removably connecting with described reflection shield.
Preferably, described radiator one side is provided with some radiation tooths.
Preferably, described radiation tooth is T-shaped structure.
The beneficial effects of the utility model are:
1. between light source and radiator, be provided with conducting strip, make light source and radiator thermal conductivity better, radiator comprises substrate and radiating subassembly, substrate is provided with some groups of radiating subassemblies, radiating subassembly comprises supporter and some fin, supporter is fixed on substrate, described some fin are circumferentially spaced apart and fix with supporter along supporter, every fin extends along supporter short transverse, between adjacent fin, form heat dissipation channel, fin is provided with cross-ventilation through hole, conducting strip is heat radiation Copper Foil, radiator one side is provided with some radiation tooths, radiation tooth is T-shaped structure, increased the area of dissipation of radiator, make cross-ventilation between fin, make LED road lamp cooling effective,
2. lens outside is coated with diffuse reflection coating layer, and the direct reflection by original technology to light, changes into diffuse reflection, thereby has reduced the dazzling sense to people;
3. radiator rear portion is fixed with fan, increase light fixture radiating rate and efficiency, thereby guarantee light efficiency and the life-span of light source, owing to adopting fan structure, radiator volume significantly can be reduced, when replacing former street lamp, can retain the shell of former street lamp, not only provide cost savings, and former street lamp outward appearance is changed little;
