The specific embodiment
As depicted in figs. 1 and 2, LED lighting device of the present invention comprises: main body 1; Lid 3 keeps a pair of pin terminal 2 of the socket 8 that is embedded in the fluorescent lamp utensil, and is engaged in main body 1; Printed circuit board (PCB) 4 is built in main body 1, is equipped with electric control circuit; LED5 is installed in printed circuit board (PCB) 4; Splicing ear 6 is used to be connected in pin terminal 2.
[embodiment 1]
Main body 1 is light diffusion part 1a that will make with transparent or semitransparent resin (for example polycarbonate resin) and combination such as the radiating part 1b that utilizes aluminium alloy etc. and realize, is cylindric, but the situation as the fin of concaveconvex shape with radiating part 1b is also arranged.
Have, main body 1 might not be this combination, also can only realize with resin again.
With the size that cooperates with existing fluorescent lamp utensil the lid 3 of the pin terminal 2 of copper alloy system has been installed, has been engaged, but for the maintenance of inside, made the structure that to take off from main body 1 at the two ends of main body 1.
Fig. 3 represent with insulative resin with a pair of pin terminal 2 lid 3 after integrally formed, but pin terminal 2 also can be installed in lid 3 by being pressed into or riveting.
In addition as shown in Figure 4, the groove 3b that gone into that is formed with assembling splicing ear 6 in the inboard of lid 3 is connected the substrate insertion groove 3a that the circuit connecting section 4a of the printed circuit board (PCB) 4 of the 6a of spring portion connection is inserted into substrate with splicing ear 6.
Have, it is insulative resin that the material of lid 3 is not limited to again, use metal also can, but for fear of electric shock, pin terminal 2 and lid 3 are by electric insulation.
At printed circuit board (PCB) 4, be formed with the circuit connecting section 4a that is connected the 6a of spring portion connection with the substrate of splicing ear 6, the electric control circuit (province's sketch map) and a plurality of LED5 that carry out rectification, Control of Voltage etc. are installed.
