For solving the problems of the technologies described above, the technical solution used in the present invention is as follows: a kind of LED car headlamp, comprise lamp body, on the top board of described lamp body, be provided with reflector, on reflector, be provided with a LED lamp of annular, be provided with circular platform type housing at YiLEDDeng center, circular platform type housing side is provided with solar cell, described circular platform type housing bottom surface is provided with circular lens, described circular platform type enclosure interior LED lamp module, described LED lamp module is surrounded by some the 2nd LED lamps, on described reflector, be provided with negative coefficient photo resistance, described some the 2nd LED lamps are connected with battery and negative coefficient photo resistance successively, above-mentioned two series arms connecting are connected with two loops of double loop controller respectively afterwards.
As preferably, described solar cell adopts non-crystal silicon solar cell.
As preferably, the angle of described solar cell and reflector is 70 °.
As preferably, the LED lamp power that the power of described the 2nd LED lamp is less than 1/5th times, and the power of the 2nd LED lamp is less than 3W.
As preferably, the structure of described Double-circuit switch comprises a button, with two sheet metals, two sheet metals are connected on button, between two sheet metals, be provided with collets, the below of each sheet metal be provided with a component from contact, loop, contact, every group of loop is connected with a series arm.
Wherein, solar cell comprises battery and solar energy tabula rasa, and described battery is connected with solar energy tabula rasa by wire.
The reflector of setting of the present invention can be strengthened the luminous intensity that of a LED lamp.When in situation about lighting in daytime or a LED lamp, solar energy tabula rasa can be charge in batteries.The preferred non-crystal silicon solar cell of solar cell, has volume little, lightweight, and the high feature of spectral absorption that LED lamp is sent.In the time opening Double-circuit switch, the light of a LED lamp is irradiated in negative coefficient photo resistance, and its resistance value is raise, and automatically the loop of the 2nd LED lamp is cut off; At night, the resistance value of negative coefficient photo resistance reduces, and the loop conducting of the 2nd LED lamp provides illumination electric energy by battery for the 2nd LED lamp.User only need to control a button, just can realize the automatic switchover of conventional illumination and emergency lighting.The bright resistance of negative coefficient is arranged on reflector, and the power of the 2nd LED lamp is less than 3W, and that can avoid causing because the 2nd LED fluorescent tube self is luminous negative coefficient photo resistance misoperation may.The angle of solar cell and reflector is 70 °, can increase to the full extent the absorption of solar cell to light.The LED power of lamp tube that the power of the 2nd LED lamp is less than 1/5th times, and the power of the 2nd LED lamp is less than 3W, can avoid due to the excessive too short problem of emergency lighting time that causes of the 2nd LED lamp power.Under this design, the emergency lighting time can reach more than 1 hour.
Brief description of the drawings
Fig. 1 is the schematic diagram of a detailed description of the invention of the present invention.
Detailed description of the invention
In order to make objects and advantages of the present invention clearer, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
With reference to Fig. 1, a kind of LED car headlamp of the present invention, comprise lamp body 1, on the top board of described lamp body 1, be provided with reflector 3, on reflector 3, be provided with a LED lamp 4 of annular, be provided with circular platform type housing 5 at the center of a LED lamp 4, circular platform type housing 5 sides are provided with solar cell 6, described circular platform type housing 5 bottom surfaces are provided with circular lens 7, the inner LED lamp of described circular platform type housing 5 module 8, described LED lamp module 8 is surrounded by some the 2nd LED lamps 10, on described reflector 3, be provided with negative coefficient photo resistance 9, described some the 2nd LED lamps 10 are connected with battery and negative coefficient photo resistance 9 successively, above-mentioned two series arms connecting are connected with two loops of double loop controller 2 respectively afterwards.。
