Abstract

A lamp cap of an LED module street lamp with high thermal diffusivity and adjustable lighting angle belongs to the technical field of semi-conductor illumination. The lamp cap comprises a lamp cap upper cover, a lamp cap lower cover, a supporting framework, a lamp cap trim cover, a junction box, a plurality of LED light source drive, a power supply and at least one LED light source module; the LED light source module is connected and fixed with the supporting framework by an end cover, the lamp cap trim cover is fixed at the head of the supporting framework, and the upper cover and the lower cover of the lamp cap are appositioned face to face and are fixedly connected at the tail of the supporting framework. By adopting LED light source and scientific and reasonable design, the invention has the advantages of high light efficiency, stability, energy saving, and environmental protection, etc. By making use of the design of modularization combination, the LED light source module can satisfy the requirements of diverse heights and lighting angles by adding or reducing LED light source modules according to application condition, thus one lamp has various usages. The invention has wide application range, low cost and convenient assembly. The lighting angle of the LED light source module can be adjusted to realize optimal light distribution requirements of different roads.

Description

technical field [0001] The invention discloses a structure of a high heat dissipation LED module street lamp lamp cap with adjustable irradiation angle, which belongs to the technical field of semiconductor lighting. Background technique [0002] At present, the light sources used for street lighting include: incandescent lamps, high-pressure mercury lamps, high-pressure sodium lamps, metal halide lamps, fluorescent lamps, etc. The main disadvantages of these lamps are: ① Not environmentally friendly: heavy metals such as mercury, lead, and arsenic are harmful to the environment ; ② high energy consumption; ③ short life. [0003] Traditional street light sources contain heavy metals and pollute the environment; LED light sources do not contain heavy metals and will not pollute the environment. Because the traditional street light source is spherical, the light divergence is not easy to control, and the light is easy to overflow the designated irradiation area, so light poll...
