Description

A solar powered LED lamp

technical field

The utility model relates to a solar powered LED lamp.

Background technique

LED lamps are used more and more widely in various lighting fields. Traditional street lighting lamps are difficult to meet higher and higher requirements due to backward technology, so they are gradually eliminated. The application of LED lamps in the field of street lighting gradually tends to Popularization, but the current LED lamps still generally rely on traditional electricity to work, the degree of dependence on traditional electric energy is high, and the cost of use is also high, and the optimal use of new energy cannot be effectively realized. Therefore, the existing LED lamps cannot further Meet the environmental protection requirements of energy saving and consumption reduction.

The use of LED lamps can effectively solve the technical defects of low efficiency and high energy consumption of traditional lamps, and meet high requirements for use. However, the LED light source chip in the LED lamp will generate a lot of heat while emitting light efficiently, and the drive of the LED light source The power supply will also generate heat, which is likely to bring safety hazards. Therefore, LED lamps need to be equipped with radiators when they are in use. The heat sink for the power supply, the existing LED street lamps ignore the heat dissipation of the driving power supply, the heat generated by the driving power supply cannot be effectively dissipated, and the continuously accumulated heat not only affects the service life of the LED lamps, but also has a large safety hazard. It poses a threat to the normal use of LED lamps. If two heat sinks are equipped in the LED lamp to dissipate heat for the LED light source and the driving power supply respectively, it will inevitably lead to a more complicated internal structure of the LED lamp, increase the volume and weight of the LED lamp, and lead to an increase in the cost of the LED lamp .
