Summary of the invention
In order to solve existing solar LED Lawn lamp above shortcomings, the utility model proposes a kind of brightness height, good heat dissipation effect, high life, can avoid dazzle, the effective solar LED Lawn lamp of bright dipping.
The utility model adopts following technical scheme:
The solar LED Lawn lamp; comprise light cover, bright dipping body, lamppost, base from top to bottom; the upper surface of described light cover is packaged with the photovoltaic cell of making opto-electronic conversion; battery and controller are housed in the described light cover; described controller comprises described photovoltaic cell of connection and charging and discharging of accumulator protection module; and LED driver module; power is housed more than or equal to 1 watt high-power LED light source in the described bright dipping body; described high-power LED light source is arranged on the aluminium base that is furnished with printed wire, and described high-power LED light source is connected with described LED driver module.
Further, described bright dipping body comprises encircling to be put at described great power LED light cup of the no end on every side, is positioned at the reflective cone of light cup below, and covers on the light shield that goes out outside described light cup and the reflective cone.
Further again, described light cover comprises loam cake, lower cover, and described photovoltaic cell is encapsulated in the end face of described loam cake, and described battery and controller are arranged on and cover under described.
Preferably, described upper cover top surface level of incline face is provided with.Can increase the photovoltaic cell that is encapsulated in upper cover top surface and the contact area of daylight like this, to absorb more solar energy.
Preferably, described lower cover is provided with the mounting groove that cooperates with described battery.
Preferably, described aluminium base pastes the bottom at described lower cover.
Preferably, evenly be furnished with stepped striped on the inwall of described light cup.
Technical conceive of the present utility model is: the Lawn lamp light source has adopted power to be not less than the great power LED of 1W, and it is heat sink to adopt the aluminium base of good heat dissipation effect to do, thereby when producing high brightness, can guarantee service life; In addition, adopted light cup and reflective cone luminous intensity distribution, the light cup does not have end cup for the high transmission rate bucket shape, the inboard promising stepped striped of cup; In the bright dipping of led light source, the sub-fraction bright dipping is to go out towards the refraction of light cup side, like this, the LED spot light is become from going out the column light source that light shield penetrates, and it is simpler and more honest visually to become; All the other major parts of LED bright dipping are to penetrate from the bottom through light cup central authorities, this part light is reflected by reflective cone, become oblique irradiation down, like this, the LED of directive bottom can be gone out anaclasis and go out, improve light emission rate,, therefore can avoid direct projection to go into the dazzle of human eye because two parts light all is oblique outgoing down.In addition, the upper cover top surface level of incline face of Lawn lamp is provided with, and can increase the photovoltaic cell that is encapsulated in upper cover top surface and the contact area of daylight like this, absorbs more solar energy, thereby the electric power abundance, and the time that can light is longer.
The beneficial effects of the utility model are: (1) brightness height, good heat dissipation effect, high life; (2) light distribution effect is good, and light is simple and honest full, free from glare; (3) electric power abundance, the time of lighting are long.
