Yet,, still can produce certain heat during its work though LED is regarded as cold light source.The operating temperature of led chip generally should be less than 50 ℃.There is data to show that when the operating temperature of LED reaches 55 ℃, its life-span will reduce half.Its heat radiation system of present LED fluorescent tube is imperfection very, existing LED fluorescent tube generally outwards dispels the heat by being located at the outer metal shade of substrate, metal shade conducts heat slower, the heat that LED produces in the course of the work is difficult in time conduct on the lampshade and be distributed in the air, causes LED to burn out owing to temperature rise is too high unavoidably.
The utility model content:
The purpose of this utility model is to provide at the deficiencies in the prior art a kind of heat dissipation base of the LED fluorescent tube fast, that radiating efficiency is high that conducts heat.
For achieving the above object, the utility model adopts following technical scheme:
The heat dissipation base of LED fluorescent tube comprises a metal substrate, and described substrate front portion is provided with the mounting groove that is used to install led chip; Described substrate back vertically is provided with a plurality of radiating fins, and described radiating fin is disposed on substrate back, has the heat exchange groove for circulation of air between two adjacent radiating fins.
The further technical scheme of the utility model is:
Described mounting groove bottom land offers the screwed hole of the led chip that is used to be spirally connected.
Offer the Wire channel in building that is used for ccontaining power line on the described mounting groove side channel wall.
Described substrate front end convexes with the position-limit foot that is used for fixing light gathering baffle-board.
Offer the chute that is complementary with LED fluorescent tube light-guiding shade edge on the described substrate.
Be connected to the locus circle at LED fluorescent tube light-guiding shade outward flange place in the top, cross section of all described radiating fins is equal.
Described radiating fin and described substrate are one-body molded.
The utility model beneficial effect is: the utility model is installed in the LED fluorescent tube, and led chip is fixed in the described mounting groove, and the led chip back side is close to the mounting groove bottom land and is installed; In the use, the heat that produces when led chip is luminous conducts to substrate through described mounting groove bottom land, and by substrate back, and the radiating fin that is arranged at substrate back with exchange heat to air, reach the heat radiation purpose, because the surface of substrate and each radiating fin is radiating surface, area of dissipation is big, and radiating effect is good; And have the heat exchange groove between two adjacent radiating fins, so radiating efficiency height.
Description of drawings:
Accompanying drawing 1 is a schematic cross-section of the present utility model;
Accompanying drawing 2 is that the utility model is installed on the schematic cross-section in the LED fluorescent tube.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described, sees that shown in the accompanying drawing 1,2, this is preferred embodiment of the present utility model; The heat dissipation base of LED fluorescent tube comprises a metal substrate 1, and described substrate 1 front portion is provided with the mounting groove 11 that is used to install led chip 2; Described substrate 1 back side vertically is provided with a plurality of radiating fins 12, and described radiating fin 12 is disposed on substrate 1 back side, and two 12 of adjacent radiating fins have the heat exchange groove 17 for circulation of air.
See shown in the accompanying drawing 2 that the utility model is installed in the LED fluorescent tube, led chip 2 is fixed in the described mounting groove 11, and led chip 2 back sides are close to mounting groove 11 bottom lands and are installed; In the use, the heat that led chip 2 produces when luminous conducts to substrate 1 through described mounting groove 11 bottom lands, and by substrate 1 back side, and the radiating fin 12 that is arranged at substrate 1 back side with exchange heat to air, reach the heat radiation purpose, because the surface of substrate 1 and each radiating fin 12 is radiating surface, area of dissipation is big, and radiating effect is good; And two 12 of adjacent radiating fins have heat exchange groove 17, so the radiating efficiency height.
See shown in accompanying drawing 1 or the accompanying drawing 2 that described mounting groove 11 bottom lands of present embodiment offer the screwed hole 13 of the led chip 2 that is used to be spirally connected; Described led chip 2 is fixed in the mounting groove 11 by described screwed hole 13.Certainly, led chip 2 also can adopt connected mode such as bonding to be fixed on described mounting groove 11 bottom lands.
See shown in the accompanying drawing 1, offer the Wire channel in building 14 that is used for ccontaining power line 4 on the described mounting groove 11 side channel walls of present embodiment.Specifically, present embodiment offers Wire channel in building 14 symmetrically on described mounting groove 11 both sides cell walls; Power line 4 is contained in the described Wire channel in building 14 and fixed-site has avoided power line 4 to twine mounting groove 11 in like this, has both made described mounting groove 11 inside succinctly, has strengthened the security performance of LED fluorescent tube again.
See shown in accompanying drawing 1 and the accompanying drawing 2 that described substrate 1 front end of present embodiment convexes with the position-limit foot 15 that is used for fixing light gathering baffle-board 5; Described position-limit foot 15 comprises drift angle 151 and hypotenuse 152; Described position-limit foot 15 is used to limit the position of light gathering baffle-board 5.Light gathering baffle-board 5 is close to led chip 2 and is installed on the described substrate 1, is used for the light that led chip 2 is sent is carried out optically focused.As shown in Figure 2, led chip 2 installations are close in described light gathering baffle-board 5 bottoms, and its side snaps in the described position-limit foot 15, and the side front end of light gathering baffle-board 5 is tight against described drift angle 151, and its outer surface is close to described hypotenuse 152; Like this, described light gathering baffle-board 5 promptly is fixed on the substrate 1, can carry out the optically focused reflection with the light that the fixed sides inclination angle is sent led chip 2, further improves the optically focused degree of LED fluorescent tube.
