The specific embodiment
As shown in Figure 1, LED fluorescent lamp lamp plate includes and covers copper circuit board 1, and what cover adjacent LED lamp pearl 2 pins 3 on the copper circuit board 1 covers Copper Foil 4 for long block, and covering has pad 5 on the Copper Foil 4, and gap 6 distances of respectively covering between the Copper Foil 4 are the 0.5-1.5 millimeter.To Be Protected from Heat for LED lamp pearl 1, it is bad to dispel the heat, will cause the luminous efficiency of LED low, shorten service life, solve the most effectual way of LED lamp pearl heat radiation, be that led chip will be lacked with outer radiating element path, it is big that area of dissipation is wanted as far as possible, the heat radiation resistance is little, what adjacent LED lamp pearl 2 pins 3 on the copper circuit board 1 were covered in employing covers Copper Foil 4 for long block, gap 6 distance of respectively covering between the Copper Foil 4 is the radiator structure of 0.5-1.5 millimeter, uses to greatest extent to cover Copper Foil 4 on the LED fluorescent lamp lamp plate 1, increases the structure of its area of dissipation, even do not adding or adding less under the situation of external fin, LED lamp pearl 2 pins 3 are lacked apart from Copper Foil 4 paths of covering of covering copper circuit board 1, and LED lamp pearl 2 pins 3 directly are welded on by pad 5 and cover on the Copper Foil 4, because it is bigger to cover Copper Foil 4 areas, the heat that produces when making 2 work of LED lamp pearl is delivered to by LED pin 3 and covers the heat radiation rapidly of Copper Foil 4 backs, avoided the formation of heat localization, not only guaranteed the service life of LED lamp pearl 2 effectively, and reduced production cost effectively.
The difference of Fig. 2, Fig. 3, Fig. 4 and Fig. 1 is: the Copper Foil 7 that covers that Fig. 2 covers adjacent LED lamp pearl 2 pins 3 on the copper circuit board 1 is the square shape; The Copper Foil 8 that covers that Fig. 3 covers adjacent LED lamp pearl 2 pins 3 on the copper circuit board 1 is the vee-block shape; The Copper Foil 9 that covers that Fig. 4 covers adjacent LED lamp pearl 2 pins 3 on the copper circuit board 1 is the convex bulk, and other principles are the same with Fig. 1.
As shown in Figure 5, cover at least one limit of copper circuit board and be provided with a long vertical bar and cover Copper Foil 10, or two long vertical bars are set cover Copper Foil, as the power line connecting line or cover Copper Foil with bulk and be electrically connected, reduce cost effectively.
As shown in Figure 6, cover two limits of copper circuit board and respectively be provided with a long vertical bar and cover Copper Foil 12,13, long vertical bar covers Copper Foil 13 and covers Copper Foil 11 in the lamp plate end with bulk and be electrically connected; This long vertical bar covers Copper Foil or covers Copper Foil in the lamp plate centre position with bulk and is electrically connected.
Fig. 7 is provided with the fixation hole configurations schematic diagram on LED fluorescent lamp lamp plate, as shown in the figure, fixing hole 14 is set, and makes LED fluorescent lamp lamp plate be convenient to fix.
