Technical Field

[0001] The invention relates to the technical field of LED lamps, and in particular to a solar street lamp with variable color temperature. Background Art

[0002] At present, my country has entered a new era of actively developing and utilizing renewable energy. As a kind of "inexhaustible" green and environmentally friendly renewable energy, solar energy has been paid more and more attention. As the technology of solar power generation becomes more mature and the price drops sharply, the market of solar lighting products has great potential. With the strengthening of people's environmental awareness and the increasing shortage of resources, the use of new energy has quickly entered people's lives. Solar street lights use sunlight as energy, charge during the day and use at night, without the need to lay complex and expensive pipelines, and the layout of lamps can be adjusted at will. They are safe, energy-saving and pollution-free. The charging and on / off process uses light-controlled automatic switches, without manual operation, stable and reliable operation, saving electricity bills, and maintenance-free. The practicality of solar street lights has been recognized by people. The application of solar photovoltaic technology to LED lighting is a truly energy-saving and environmentally friendly green lighting. The solar LED street lights that have appeared in recent years are a challenging and attractive attempt to apply LED photovoltaic technology to LED public lighting.

[0003] In the prior art, solar street lights use a single color temperature. On rainy days, warm yellow light with a color temperature of 3000K to 3500K is needed. Light of this color temperature has strong penetrating power and can provide good lighting effects.

[0004] In clear weather, you need to choose white light with a color temperature of 5000K to 6000K. Although the light of this color temperature has relatively weak penetration, it can provide better lighting effects in clear weather.

[0005] Therefore, how to provide a solar street light with variable color temperature to solve the problems existing in the prior art is of great significance for its application. Summary of the invention

[0035] The variable color temperature lamp 6 comprises a lamp housing 8 and an LED lamp board 18 . The LED lamp board 18 is installed inside the lamp housing 8 . A lamp cover 12 is installed at the bottom end of the lamp housing 8 .

[0036] A rotating shaft 21 and a rotating shaft 23 are rotatably connected on both sides of the lamp housing 8, and both ends of the rotating shaft 23 are fixedly connected to a rotating gear 19.

[0038] The surface of the color temperature adjusting film 20 is provided with two rows of tooth holes, which mesh with the rotating gear 19 and the rotating gear 2 22 . By providing the tooth holes, the rotation accuracy of the color temperature adjusting film 20 can be improved and the color temperature adjusting film 20 can be prevented from slipping.

[0039] The two ends of the rotating shaft rod 23 extend to the outside of the lamp housing 8 and are fixedly connected to the rotating pulley 4 24 and the rotating pulley 2 13.

The rotating belt one 10 and the rotating belt two 16 can drive the cleaning rod 11 to rotate. At this time, it is rainy weather, and rainwater acts as a cleaning agent. The cleaning rod 11 can clean the surface of the lampshade 12.

[0046] When the weather is clear, the rain sensor 5 transmits the collected signal to the single chip microcomputer, and the single chip microcomputer controls the start of the motor 15.
