In the lamp tail assembly electron rectifier is installed, and is encapsulated in the lamp tail assembly by cover plate.
The led light source assembly is tightened on the radiator assembly through screw thread.
The contact of LED lamp pearl is a resilient contact.
Cathode contact on the circuit board and cathode contact are for being two concentric circles at center with the metal bolts, and the bottom is communicated with the positive pole and the negative power supply of LED light fixture.
Be distributed with through hole on the arc column face chord cylinder of the radiator housing of radiator assembly, the heat-conducting plate.
The heat-conducting plate that in the radiator housing of radiator assembly, is provided with has 4～10.
The heat-conducting plate that in the radiator housing of radiator assembly, is provided with has 6.
The bottom of the concave panel of the radiator housing of radiator assembly has LED lamp pearl installation position to become array distribution.
The outer surface of the arc column face of the radiator housing of radiator assembly is provided with fin.
After adopting technique scheme, the utlity model has following advantage:
1, because this LED lamp pearl is directly installed on the top of metal bolts; Metal bolts passes circuit board and directly is connected on the radiator; Thereby will effectively LED lamp pearl and radiator be combined together closely; Change the present situation that traditional high-power LED light source carries out heat conduction by heat conductive silica gel, can promote the heat conduction efficiency between LED lamp pearl and the radiator greatly, the service life that effectively guarantees led light source was greater than 50,000 hours.
2, this LED lamp pearl is directly installed on module of top formation of metal bolts, adopts modularized design, changes under when damaging replacing, directly selecting to get final product, and makes the assembly technology simplification, does not need professional and instrument, and it is extremely convenient to operate, and has saved cost of labor.
3, because the radiator housing is an arc post to which the strings of a musical instrument are attached shape housing; The both ends open of radiator housing, two sides of its arc column face are vertical facade, in the radiator housing, are provided with heat-conducting plate axially-aligned and that be connected with arc column face, post to which the strings of a musical instrument are attached face; Therefore form the heat dissipation channel that many hot-airs flow in the radiator component internal; The outer surface of the arc column face of radiator housing is provided with fin and the stud heat-conducting plate also can serve as radiating surface, and heat exchange area increases, and the heat discharge efficiency is high.
4, the housing parts of this radiator assembly can disposal molding, can be the entire heat dissipation body as an assembly, and under damaging when changing directly choosing, change and get final product, make the assembly technology simplification; Can LED lamp pearl be directly installed on the radiator assembly simultaneously, the convenient installation, it is extremely convenient to operate.
