Embodiment 1

[0025] Such as figure 1 Shown system structure of the present invention. The lithium-ion battery with a voltage of 3.6V, the white LED lamp is a street lamp with a full parallel structure, and the working voltage is 3.6V. The lithium-ion battery and photovoltaic modules are fixed above the LED lamp head through a bracket. There is a charge controller between the photovoltaic module and the lithium-ion battery to prevent overcharging of the lithium-ion battery. There is a controller connected between the lithium-ion battery and the LED street lamp, but the controller itself has no boost and buck functions. The basic function of the controller includes two parts. The first part is to automatically turn on and off the LED light based on the ambient brightness obtained by the environmental monitoring system. The second part is to control the charging and discharging process of the lithium-ion battery to prevent the lithium-ion battery from overcharging and Over-discharge causes ...

Embodiment 2

[0027] The basic structure and principle are as described in Example 1, but the lithium-ion battery is not fixed above the LED lamp head through a bracket, but the lithium-ion battery is used for its high energy density and small size, and is installed together with the charge controller in the LED street lamp head. Inside the casing, the lithium-ion battery is directly attached to the back of the light-emitting diode, and the side where the two are in contact is coated with insulating and heat-conducting silica gel to fasten the two parts into one, such as figure 2 shown.

Embodiment 3

[0029] The basic structure and principle are as described in Embodiment 1, but the lithium-ion battery is not fixed above the LED lamp head through the bracket alone, but an ultra-thin polymer lithium-ion battery is used. The polymer lithium-ion battery and the photovoltaic module use a common The borders are fixed together. Such as image 3 shown.

Abstract

The invention relates to a solar white-light LED integrated illumination system, which comprises a lithium ion battery, a white-light LED lamp, an environment sensor, a photovoltaic component, a battery charging controller and a system controller, wherein the photovoltaic component converts solar energy into direct current, and stores the direct current into the lithium ion battery through the battery charging controller; the lithium ion battery and the white-light LED lamp have the consistent work voltage of 3.6V, and a lithium ion battery pack and the LED lamp with different work voltages can be obtained through matched series and parallel structures, and work directly without a transformation system therebetween; and the system controller can turn on and turn off the LED lamp by judgingthe environment light intensity detected by the environment sensor. The integrated illumination system of the photovoltaic component, the white-light LED lamp and the lithium ion battery is formed bymechanical fastening, chemical bonding and direct growth of small devices.

Description

technical field [0001] The invention relates to the field of lighting systems, in particular to a solar white LED integrated lighting system based on lithium-ion batteries and light-emitting diodes. Background technique [0002] The working voltage of lithium-ion batteries is 3.4-3.6 volts, which is exactly the working voltage of light-emitting diodes (LEDs) in semiconductor white light lighting that the country vigorously promotes (the rated working voltage of white, blue, and pure green LEDs is 3.0-3.6V, red, Yellow, yellow green, orange are 1.8 ~ 2.4V, rated current is 10 ~ 20mA). Lithium-ion batteries have a charge-discharge conversion rate of more than 90%, which has a good performance advantage. The LED lighting is a safer lighting source than using a high-voltage power supply, especially suitable for public places; the energy consumption is 80% lower than that of an incandescent lamp with the same light effect, and each unit LED chip is a square of 3 to 5 mm, so it c...
