Abstract
The utility model discloses a long-life L ED ball bubble, including lamp holder, power lid, radiator, printing opacity cover, drive power supply, light source board, its characterized in that drive power supply, including the rectification filter unit, the switch transform unit is arranged in respectively on 2 different circuit substrate boards, the rectification filter unit set up to solitary 1 rectification filter board, be fixed in the power lid, the switch transform unit set up on the aluminium base board of light source board, the lamp holder, the rectification filter board, the switch transform unit, the light source board is electric connection in proper order, the beneficial effect lies in that the life-span of L ED ball bubble has been increased.
Description
Technical Field
The utility model relates to an L ED ball bubble, especially a long-life L ED ball bubble.
Background
L ED ball bubble is an illumination lamps and lanterns that use luminous L ED as the light source, including the lamp holder, the power lid, the radiator, the printing opacity cover, drive power supply, light source board current L ED ball bubble, drive power supply is a monoblock and has contained the rectification filter unit, the circuit board of switch transform unit, the effect is exchanging the power frequency, becomes high voltage direct current through the rectification filter unit, becomes invariable direct current through the switch transform unit again, gives the luminous L ED lamp pearl on the light source board and supplies power.
L ED bulb generates a large amount of heat when working, the whole temperature is high, the service life is short, wherein the influence on the service life is the largest in the driving power supply, the electrolytic capacitor in the rectification filter unit, the service life of the electrolytic capacitor determines the whole service life, the service life of the electrolytic capacitor is determined by the self temperature of the electrolytic capacitor when working, the temperature is higher, the service life is shorter, the main heating element of the driving power supply is positioned in the switch conversion unit, the existing L ED bulb has the warming effect on the electrolytic capacitor in the rectification filter unit because the rectification filter unit and the switch conversion unit are on the same circuit substrate, and the heat generated by the switch conversion unit shortens the service life of the electrolytic capacitor and correspondingly shortens the whole service life of the L ED bulb.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the not enough of prior art, provide a long-life L ED ball bubble.
The utility model adopts the scheme that: the rectification filtering unit and the switch conversion unit are respectively arranged on 2 different circuit substrates; the rectifying and filtering unit is set as 1 independent rectifying and filtering plate and is fixed in the power cover; the switch conversion unit is arranged on the aluminum substrate of the light source plate; the lamp holder, the rectification and filtering plate, the switch conversion unit and the light source plate are electrically connected in sequence.
Compared with the prior art, the utility model relates to a long-life L ED ball bubble has prolonged electrolytic capacitor's life-span to L ED ball bubble holistic life-span has been increased.
Drawings
Fig. 1 is an internal structure diagram of a conventional L ED bulb.
Fig. 2 is an internal structure diagram of a long-life L ED bulb in embodiment 1.
FIG. 3 is an internal structure diagram of a long-life L ED bulb in embodiment 2
In the figure: the LED lamp comprises a lamp holder 1, a power cover 2, a radiator 3, a light source plate 4, a light-transmitting cover 5, a driving power supply 6, a rectifying and filtering plate 7 and a switch conversion unit 8.
Detailed Description
In fig. 1, a driving power supply 6 is an integral driving power supply board of a conventional L ED bulb, and is fixed in a power supply cover 2, and a lamp holder 1, the driving power supply 6 and a light source board 4 are electrically connected in sequence.
In fig. 2, the rectifying and filtering plate 7 is fixed in the power cover 2, the switch conversion unit 8 is welded on the light source plate 4, and the lamp holder 1, the rectifying and filtering plate 7, the switch conversion unit 8 and the light source plate 4 are electrically connected in sequence.
In fig. 3, the rectifying and filtering plate 7 is fixed in the cavity formed after the lamp cap 1 and the power cover 2 are connected, and is further away from the switch conversion unit 8, so that the temperature of the rectifying and filtering plate 7 is reduced.
Claims (2)
1. A long-life L ED bulb comprises a lamp cap, a power supply cover, a radiator, a light-transmitting cover, a driving power supply and a light source board and is characterized in that the driving power supply comprises a rectifying and filtering unit and a switch conversion unit, the rectifying and filtering unit is respectively arranged on 2 different circuit substrates, the rectifying and filtering unit is formed by 1 independent rectifying and filtering board and fixed in the power supply cover, the switch conversion unit is arranged on an aluminum substrate of the light source board, and the lamp cap, the rectifying and filtering boards, the switch conversion unit and the light source board are sequentially and electrically connected.
2. The long-life L ED bulb as claimed in claim 1, wherein the rectifying and filtering plate is fixed in a cavity formed by the connection of the lamp cap and the power supply cover.
