Referring to fig. 1, an embodiment of a constant temperature energy storage battery structure is provided, including a housing having an LED light source, a battery 200, and a controller 700 disposed therein. The LED light source comprises a first LED light source 110 and a second LED light source 120, a radiator 111 is arranged on the first LED light source 110, the radiator 111 is preferably made of aluminum profiles and provided with a plurality of radiating fins, and the LED light source is light and firm, easy to process and produce and good in heat conducting performance. The battery 200 is used for electric energy storage. The battery 200 supplies power to the first LED light source 110 and the second LED light source 120 through the controller 700. The phase change material 400 is coated outside the battery, the temperature monitor 600 is arranged in the phase change material 400, and the temperature monitor 600 is used for detecting the temperature of the battery 200. In the present embodiment, the heat conduction member 300 is provided, and as shown in fig. 1, in the present embodiment, the heat conduction member 300 is "i" shaped, and is preferably machined from an aluminum alloy member, and has good heat conductivity and is easy to machine and produce. Specifically, two ends of the heat conductor 300 are large-area thin aluminum alloy plates, and the two aluminum alloy plates are connected into a whole through an aluminum alloy connecting rod in the middle for heat transfer. Wherein, one aluminum alloy plate of the heat conduction member 300 is closely contacted with the heat dissipation surface of the second LED light source 120, and the other aluminum alloy plate of the heat conduction member 300 is deep into the phase change material 400 and is contacted with the phase change material 400 in a large area. Because the LED light source during operation, the heat that produces is far greater than the heat that the battery work produced, therefore, when the street lamp during operation, the temperature of second LED light source 120 is higher than battery 200 and its peripheral phase change material 400, according to the heat law of high to low transmission by the temperature, the heat that second LED light source 120 work produced passes through heat conduction piece 300, to battery 200 and phase change material 400 side transmission, thereby heat the heat preservation to battery 200, the energy loss problem that battery 200 self-heating produced has been solved, the energy is effectively utilized, make the system more energy-conserving, supplementary second LED light source 120 dispels the heat simultaneously.

In this embodiment, the controller 700 employs a feedback mode to regulate the power of the second LED light source 120: when the temperature of the battery 200 fed back is lower than the optimal working temperature range, the controller 700 increases the power of the second LED light source 120, so that the second LED light source 120 generates more heat, and the heat is transferred to the battery 200 through the heat conduction member 300 to heat and insulate the battery 200; when the temperature of the battery 200 fed back is higher than the optimal operating temperature range, the controller 700 reduces the power of the second LED light source 120 to reduce the heat generated by the second LED light source 120, thereby reducing the heat transferred from the second LED light source 120 to the battery 200 and lowering the temperature of the battery 200. Through the feedback control of the controller 700, it is possible to ensure that the battery 200 operates in the optimum operating temperature range for more time.

In the embodiment, the LED light source is divided into the first LED light source 110 and the second LED light source 120, wherein the second LED light source 120 conducts the generated heat to the battery 200 through the heat conducting member 300 for heating and insulating the battery 200, which not only solves the heat dissipation problem of the second LED light source 120, but also enables the battery 200 to obtain sufficient heat to maintain the optimal working temperature, and avoids energy loss caused by self-heating of the battery 200, so that the system is more energy-saving; the controller 700 adjusts the power of the second LED light source 120 according to the temperature of the battery 200 fed back by the temperature monitor 600, so as to influence the heat generated by the second LED light source 120 and ensure that the battery 200 works in a constant temperature state; adopt phase change material 400 parcel battery 200, because of phase change material 400 has the heat absorption on the phase change point, exothermic characteristics under the phase change point, phase change material 400 heat absorption energy storage when the temperature is higher, phase change material 400 release heat when the temperature is lower, keep warm for battery 200 with temperature compensation, make battery 200 temperature more stable controllable. The first LED light source 110 can cooperate with the second LED light source 120 to perform power adjustment, so as to ensure stability of lighting effect.
Further, in this embodiment, the phase-change material 400 is provided with the insulating layer 500 made of insulating cotton, so as to reduce the heat dissipation of the battery 200 and the phase-change material 400, reduce the energy loss, and improve the energy-saving effect.
In the battery heat insulation structure in the prior art, a heating source for the battery comes from the working heat of the battery, so that the energy consumption of the battery is increased, the electric energy of the lamp can be reduced, the illumination of the lamp is influenced, and the heat generated by the self-working of the battery is not enough to maintain the proper temperature of the whole battery. In contrast, the constant-temperature energy storage battery structure of the invention uses the heat of the LED light source which needs to be processed by the heat radiator for heating and heat preservation of the battery 200, provides a large amount of stable heat sources, not only solves the problem of heat dissipation of the light source, but also enables the battery 200 to obtain sufficient heat to maintain the optimal working temperature, avoids the extra energy loss of the battery 200 due to self-heating, and enables the system to be more energy-saving.
In prior art's battery insulation construction, adopt the mode of battery self-heating, need deal with the difference in temperature through the mode of adjusting the battery: the lamp is required to be heated automatically in winter to discharge more, and is less in summer, so that temperature adaptation is achieved, and unreasonable phenomena that the working time of the lamp is less in winter at night and the working time of the lamp is long in summer at night are caused; in order to solve the problem of long night in winter and the need of maintaining effective illumination time, and to cope with the energy loss caused by self-heating of the battery, the capacity of the battery pack has to be increased, thereby causing a great increase in cost. Compared with the prior art, the constant-temperature energy storage battery structure can avoid the extra energy loss generated by self-heating of the battery 200, does not influence the power of an LED light source, ensures the lighting effect of a lamp, can keep the effective lighting time without increasing the capacity of the battery 200, and saves a large amount of cost.
In order to better control the temperature of the battery to be constant and the total output power of the lighting fixture to be constant, the present embodiment further divides the LED light source into two parts, namely, the first LED light source 110 and the second LED light source 120. Wherein the heat generated by the second LED light source 120 is conducted to the battery 200 through the heat conductor 300, the temperature monitor 600 feeds back the temperature of the battery 200, and the power P2 of the second LED light source 120 is adjusted by the controller 700. When the temperature is lower, the P2 is increased, so that the second LED light source 120 generates more heat to heat the battery 200; when the temperature is higher, P2 is lowered, reducing the heat generated by the second LED light source 120. Meanwhile, the power P1 of the first LED light source 110 is adjusted relative to the power P2 of the second LED light source 120, so as to ensure the power sum of the two to be constant, so that the total power of the lamp is constant, and the stability of the lighting effect is ensured. By dividing the LED light source into two parts for separate control, the heat conduction of the heat conduction piece 300 can be better matched, and the constant temperature work of the battery 200 can be realized on the premise of not increasing the battery capacity of the lamp and not influencing the illumination effect of the lamp.
