Description

Lighting device

The present invention relates to a lighting device, and more particularly to a lighting device for outdoor use.

As a new generation of light source, the light-emitting diode can not replace the traditional incandescent lamp on a large scale. However, it has the advantages of long working life, energy saving and environmental protection, and is generally favored by the market. Moreover, the module composed of the light-emitting diode can generate a high-power, high-brightness light source, and thus will widely and revolutionarily replace the existing light source such as a conventional incandescent lamp, thereby becoming a main light source that meets the theme of energy conservation and environmental protection.

Therefore, the currently used light-emitting diode lamps, regardless of the street lamp and the lawn lamp, need to be provided with a heat dissipation structure to solve the heat dissipation problem, and they are usually mounted and fixed by being mounted on the lamp pole. However, these commonly used light-emitting diode lamps usually have no light-emitting or light-guiding functions regardless of the street lamp or the lawn lamp, and the light-emitting diode lamps have only two working states: full light or full light. In many cases, it causes a lot of inconvenience and waste. For example, when no pedestrians pass, the LEDs are fully turned on and the energy is wasted. However, if it is completely turned off, it will affect the direction of pedestrians in the distance.

In view of the above, it is necessary to provide an illumination device having a light-emitting fixed rod.

A lighting device includes a fixing rod and a lamp mounted on the fixing rod, the fixing rod includes a light guiding cylinder, a plurality of light guiding plates housed in the light guiding barrel body and a lighting unit, the light guiding barrel barrel A plurality of light guiding holes are defined in the wall, and the inner wall of the light guiding cylinder body is provided with a locking portion, and each of the locking portions extends inwardly while extending to both sides, so that the two sides of the locking portion are respectively connected to the light guiding cylinder wall An angle is formed between the inner walls, and the opposite angles of the two adjacent latching portions just engage the two side edges of the light guide plate to fix the light guide plate.

The illumination light generated by the illumination unit of the illumination device is reflected and projected by the light guide plate and then projected through the light guide hole on the light guide cylinder body, so that the lamp can pass through the fixed rod when the pedestrian is not close to the pedestrian. The faint light projected by the light guiding hole guides the pedestrians in the distance, and the lighting effect generated at the same time can also play an effect to enhance the aesthetic effect of the lighting device.
