Description

Technical Field

[0001] The invention relates to the technical field of lamps, and in particular to a street lamp head. Background Art

[0002] The most common existing street lamp structure includes a lamp pole and a lamp head installed on the top of the lamp pole. The spherical lamp head is a more common shape. However, the existing lamp heads, especially the spherical lamp heads, are all equipped with a light source that shines directly downward on the top. The light has no tilt angle and is evenly distributed outward with the lamp pole as the center. This light distribution method is relatively traditional and old, resulting in high light illumination below the lamp pole, but weak light illumination between the two lamp poles and the inner side of the road. The illumination is uneven. The street lamps are all installed on the roadside. The above light distribution method is to radiate outward with the lamp pole as the center. In this way, most of the light does not shine on the road surface where vehicles or pedestrians are driving. The light resources are not used in the best way, the light utilization rate is low, and the light effect is average. In order to improve the brightness of the road surface where vehicles are driving and pedestrians are walking, the brightness can only be improved by increasing the power of the lamp head, which consumes a lot of energy, causing energy waste, and also causing light pollution, which is not energy-saving and environmentally friendly. Moreover, the light source of the existing lamp head generally only emits light outward through one light distribution, and the light effect is not good.

[0003] In addition, LED light sources are widely used due to their advantages such as energy saving, low carbon, long life, good color rendering, high light efficiency, good luminous effect, and fast response speed. However, heat dissipation is an important problem that LED light sources need to solve. The quality of heat dissipation is directly related to the luminous effect and life of the lamp. LED light sources generate a lot of heat, and the heat is concentrated in the small LED chip, which will make the internal temperature of the LED chip higher and higher, which will not only accelerate the aging of the lamp and shorten its service life, but also cause the chip to burn out in severe cases.

[0004] Therefore, how to achieve precise lighting towards the driving road or pedestrian road, novel and reasonable lighting distribution method, full utilization of light resources, high light utilization rate, ideal lighting efficiency, low energy consumption, no light pollution, energy saving and environmental protection, using secondary lighting distribution method, ideal lighting effect, multiple heat dissipation guarantees, high thermal conductivity and heat dissipation efficiency, ideal heat dissipation effect, simple and reasonable structure, and suitable for mass production of street lamp heads is a technical problem that needs to be solved urgently in the industry.
