Problems solved by technology

In the prior art, road lights generally require high brightness and concentrated light emission, so high-power LEDs are generally used, otherwise it is difficult to meet the requirements. However, due to the limitations of the existing technology, the generally used high-power LEDs have relatively large power and low current flow. Increase at the same time, the luminous area also becomes larger, it will emit a lot of heat and cause heating problems, and the actual energy consumption is also more; so, the power loss increases at the same time, it is difficult to concentrate the light

Embodiment 1

[0026] As shown in Figure 1, this embodiment provides an LED street lamp, the LED street lamp includes a lamp housing 101 and a lamp holder 103 that are fixedly connected, and the LED street lamp is fixed on the side of each road through a lamp pole, for the road Provide lighting for walking vehicles and pedestrians.

[0027] The lamp housing 101 is provided with a heat dissipation device 102, and the heat dissipation device 102 can be one or more heat dissipation fins, or one or more heat dissipation holes, or a heat dissipation plate, or a fan, etc., most preferably a heat dissipation Each heat sink or heat dissipation hole can be integrated with the lamp housing, that is, the integrally formed heat dissipation holes or heat dissipation fins are provided on the lamp housing 101, which takes up little space and has a good heat dissipation effect.

[0028] The lamp housing 101 is fixedly connected to the lamp holder 103, and the fixed connection may be clamping, screwing, weld...

Embodiment 2

[0035] As shown in Figure 2a, on the basis of the above examples, in the LED street lamp, each LED unit is provided with an LED thin film chip 201 and an LED thin film chip 202, and the interfaces between the LED thin film chip 201 and the LED thin film chip 202 are the same , that is, the LED thin film chip 201 and the LED thin film chip 202 are stacked in parallel, and the interfaces of the LED thin film chip 201 and the LED thin film chip 202 are arranged on the same plane to form an integral interface 203, so that the LED unit can The luminous surface reaches the minimum, and the luminance is the brightest.

[0036] For example, the arrangement on the same plane specifically means that after stacking, each LED thin film chip is located between two parallel or substantially parallel planes, and the physical center or geometric center of each LED thin film chip is located on the same plane.

[0037] Alternatively, as shown in Figure 2b, on the basis of the various examples i...

Embodiment 3

[0041] On the basis of the above examples, the LED street lamp described in this embodiment also includes a solar device, and the solar device includes a solar panel, a battery and a light control switch;

[0042] The solar cells on the solar cell board may be one of polycrystalline silicon solar cells, monocrystalline silicon solar cells, thin film solar cells, or organic solar cells. The solar battery panel is fixedly connected to the lamp holder, and is fixed on the side of the road through the lamp pole. By fixing the solar battery panel to the lamp holder, the solar battery panel and the lamp holder can be stably fixed relative to the lamp pole.

[0043] The solar battery panel is connected to the storage battery for receiving sunlight, converting light energy into electrical energy and storing it in the storage battery; the storage battery is electrically connected to the lamp holder, and through electrical transmission, provides The LED street lamp provides voltage, and...

The LED street lamp has the advantages of high brightness, low loss and concentrated illumination.

Description

technical field [0001] The present invention relates to an LED lighting device, in particular to an LED street lamp and an LED street lamp display system Background technique [0002] At the present stage, under the circumstances of global pursuit of health, environmental protection pressure, and energy crisis, semiconductor lighting has been recognized by the world as an important way of health, energy saving and environmental protection, and its application scope is expanding at a faster speed. [0003] Because LED street lamps have the characteristics of long life, high light source, no radiation, and low power consumption, LED semiconductor light sources have been widely used in the lighting field in recent years. In the prior art, road lights generally require high brightness and concentrated light emission, so high-power LEDs are generally used, otherwise it is difficult to meet the requirements. However, due to the limitations of the existing technology, the high-powe...
