The material is light aluminum alloy, which has the advantages of light weight, good heat dissipation and high strength. Surface anodized treatment, with strong corrosion resistance, even in bad environment, can ensure the normal use of lamps.
LED street lamp head heat dissipation technology, generally used for heat conduction plate mode, is a piece of 5mm thick copper plate, in fact, it is an even temperature plate, the heat source temperature off; There are also heat sinks, but they are too heavy. The weight is very important in the system of street lamp head. Generally, the height of street lamp head is more than one meter high. If it is too heavy, the risk will increase. Domestic manufacturers use the world's first needle-shaped heat dissipation technology, needle-shaped radiator heat dissipation efficiency than the traditional chip radiator has a great extent to improve, can make the LED knot temperature than the ordinary radiator low 15℃ above, and waterproof performance than the ordinary aluminum profile radiator is better, at the same time in weight and volume has been improved.
The cooling way
There are: natural convection heat dissipation, add fan forced heat dissipation, heat pipe and loop heat pipe, etc. The system of forced heat dissipation by fan is complex and has low reliability. However, street lamp head has the advantages of outdoor use at night, heat dissipation surface located on the side and small size restrictions, which are conducive to natural convection heat dissipation. Therefore, LED street lamp head is recommended to choose natural convection heat dissipation mode as far as possible.
Heat dissipation design problem
Heat dissipation fin area is set at random, unreasonable cooling fin arrangement, lamps and lanterns of the heat dissipation fin failed to consider the use of lamps and lanterns decorate way, affect the effect of fin, emphasis on heat exchange links, ignore the convection part, although many manufacturers to consider a variety of measures: loop heat pipe and heat pipe, thermal conductivity silicone grease, etc., but don't realize ultimately depends on the surface area of lamps and lanterns, heat dispersion,. Ignore the balance of heat transfer, if the fin uneven temperature distribution in the serious, will cause part of fin did not play a role or function is limited.
No bad glare, no strobe. Eliminate glare caused by ordinary street lamp, visual fatigue and line of sight interference, improve the safety of driving; Start without delay, power up to normal brightness, no need to wait, eliminating the traditional street lamp long start process; Environmental protection no pollution: no lead, mercury and other pollution elements, no pollution to the environment;
Combined with solar energy is an excellent partner, give full play to the advantages of LED dc low-voltage work and energy conservation and environmental protection, combined with solar photovoltaic panels and LED light source, to achieve the best cost performance and high reliability for customers.
