Manufacturing Method of LED street lamp assembly

The utility model relates to a street lamp assembly, in particular to an LED street lamp assembly.
【Background technique】
Road lighting is an important part of urban lighting. Traditional street lamps are often used. High-pressure sodium lamps emit 360 degrees, and the shortcomings of large light loss have caused a huge waste of energy. At present, the global environment is deteriorating day by day, and all countries are developing clean energy. With the rapid growth of the national economy, the contradiction between my country's energy supply and demand has become increasingly prominent, and there has been a serious shortage of power supply, and energy conservation is an urgent problem to be solved. Therefore, the development of a new type of high-efficiency, energy-saving, long-life, high color rendering index, environmentally friendly LED street lights is of great significance to the energy saving of urban lighting.

[0003] Road lighting is closely related to people’s production and life. With the acceleration of my country’s urbanization process, LED street lights have directional light emission, low power consumption, good driving characteristics, fast response speed, high earthquake resistance, long service life, green environmental protection, etc. The advantages have gradually entered people's field of vision and become the world's most energy-saving new generation of light sources that have the advantage of replacing traditional light sources. Therefore, LED street lights will become the best choice for road lighting energy-saving transformation.

0004] However, due to the high power and heat generation of the LED street lamp, the existing heat sink cannot perform efficient heat transfer, which affects the life of the LED street lamp chip.
[Utility model content]
[0005] The present utility model designs an LED street lamp assembly, which solves the technical problem that (1) the existing LED street lamp cannot adjust the illumination range after installation; (2) the existing LED street lamp cannot achieve the best performance under limited power Good lighting effect;

(3) The LED street lamp has high power and heat generation. The existing radiator cannot perform efficient heat transfer, which affects the life of the LED street lamp chip.
[0006] In order to solve the above-mentioned technical problems, the present utility model adopts the following solutions:
[0007] Led Street Light Components, including a radiator (1), a light emitting unit (2), a main cooling fan (3), a reflection angle adjustment device (4), a transparent lampshade (5) and a led street light housing (6), heat dissipation The device (I) is composed of multiple heat sinks (11). The multiple heat sinks (11) form a groove structure and are located outside the housing (6). The transparent lampshade (5) and the light-emitting unit (2) are placed in the groove structure It is characterized in that: the light-emitting unit (2) is composed of continuous V-shaped mounting slots (24), and the first oblique side of each V-shaped mounting slot (24) is connected with a circuit board (21), and the circuit board (21) A plurality of LED chips (22) are connected in series on the upper side; the second oblique side of each V-shaped mounting groove (24) is plated with a reflective film (25), and the LED chip (22) is arranged opposite to the reflective film (25); each The joint of the first and second oblique sides of the V-shaped mounting groove (24) is a heat dissipation base (26), and a ventilation hole (23) is opened on the heat dissipation base (26); the reflection angle adjustment device (4) passes through Squeeze the first and second oblique sides of the V-shaped mounting groove (24) to control the opening angle of the V-shaped mounting groove (24); the reflection angle adjusting device (4) includes a micro motor (41) and a moving nut (42) , Angle adjusting rod (43), threaded rod (44), first bearing (45) and second bearing (46), each angle adjusting rod (43) is located in two adjacent V-shaped mounting grooves

In the V-shaped space between (24), a plurality of angle adjustment rods (43) are arranged in parallel and there is a common connecting end (431), and the common connecting end (431) is connected to the threaded rod by moving the nut (42) (44) Screw connection, the upper and lower ends of the threaded rod (44) are respectively restricted by the first bearing (45) and the second bearing (46), and one end of the threaded rod (44) is connected with the micro motor (41).
