LED module street lamp cap with adjustable irradiation angle and high thermal diffusivity

Abstract

The invention discloses an LED module street lamp cap with adjustable irradiation angle and high thermal diffusivity, and belongs to the technical field of semiconductor lighting. The LED module street lamp cap comprises a lamp cap upper cover, a lamp cap lower cover, a support framework, a lamp cap end cover, an LED light source driver, and an LED light source module, wherein the lamp cap end cover is fixed on the head part of the support framework; the lamp cap upper and lower covers are in involutorial connection, fixed on the tail part of the support framework and accommodate the tail part inside; the LED light source driver is arranged in a cavity formed through the involutorial connection of the lamp cap upper and lower covers; and the LED light source module adopts a modularized combination design, is vertically fixed in the middle of the support framework, and can rotate in a certain radiation angle range. The LED module street lamp cap applies the LED light source, is matched with scientific and reasonable design, and has the advantages of high light efficiency, stability, energy conservation, environmental protection, convenient assembly and good radiating effect.

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...

Problems solved by technology

[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

[0008] At present, there are many kinds of LED street lamps at home and abroad, and their performance is uneven. Due to the constraints of LED lamps in terms of quality and heat dissipation requirements, it is difficult to meet the lighting needs of ultra-high-power LED street lamps.
