Description

Technical Field

[0001] The present invention relates to the technical field of LED street lamp caps, and more specifically, to an LED street lamp cap based on multiple light-emitting units. Background Art

[0002] With the acceleration of urbanization and the improvement of people's awareness of environmental protection and energy saving, traditional street lamp heads such as high-pressure sodium lamps are gradually being eliminated due to their high energy consumption, low light efficiency, short life and other shortcomings. LED street lamp heads have become the mainstream choice for urban lighting with their advantages of high efficiency, energy saving, environmental protection and long life.

[0003] Existing street lamp lamp heads often have a small number of LED light-emitting units, and these LED light-emitting units usually adopt a working mode of being turned on and off at the same time. When some of the LED light-emitting units are damaged, manual inspection is often required to find them. Even if the inspectors find the damaged LED light-emitting units, it is difficult to repair and maintain them immediately due to the complexity of the street lamp system and the professionalism of maintenance, which will significantly affect the lighting effect of the entire street lamp. In addition, during long-term lighting, when the ambient temperature is high and the heat generated by the LED light-emitting unit is large, it can only continue to be used. Long-term high-temperature operation may reduce the service life of the LED light-emitting unit. Summary of the invention

[0004] The present invention aims to overcome the defects of the prior art and provide an LED street lamp holder based on multiple light-emitting units.

[0006] Furthermore, a light intensity sensor is installed on the top plate.

[0007] Therefore, when the LED light-emitting unit is rotated to below the light intensity sensor, it is possible to detect whether the LED light-emitting unit is damaged.

[0008] Furthermore, a control unit is installed in the housing.

[0009] Furthermore, the inner annular rotating plate and the fixed column are connected via a bearing.

[0052] Working principle: The lamp holder of this application, when in normal use, Figure 1-2 As shown, under the action of the first limit lever and the second limit lever, three of the six LED light-emitting units can be abutted together and extended out of the shell, and the other three LED light-emitting units are also abutted together and located inside the shell, so that the three LED light-emitting units extending outside the shell are used for lighting, and the three LED light-emitting units located inside the shell are turned off and not used.

Therefore, when damage is found, the LED light-emitting unit extending out of the housing can be replaced. And when it is found that the temperature of the LED light-emitting unit extending out of the housing is too high, the LED light-emitting unit extending out of the housing can be replaced, so as to avoid the LED light-emitting unit being used in a high temperature state for a long time.

[0055] Although the present invention has been illustrated and described with respect to the preferred embodiments, it will be appreciated by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
