Problems solved by technology

However, there are still the following disadvantages in actual use: the driving power is fixed in the power box, and the power box and the high-power LED mounting plate for fixing the light source are all installed on the lamp body radiator, the heat generated by the light source and the heat generated by the driving power Both can only be dissipated through the radiator of the lamp body, and the heat generated by the two is superimposed on each other, which not only has higher requirements on the radiator of the lamp body, but also has an unsatisfactory heat dissipation effect.
[0005] To sum up, the existing LED bulbs cannot avoid the problem of thermal superposition of the light source and the driving power supply, which in turn causes damage to both the light source and the power supply.

Abstract

The invention relates to a light-emitting diode (LED) bulb lamp which comprises a radiator, a light source piece, a lens, an installation seat, a power supply and a lamp cap; one end of the power supply is fixedly arranged in the seat cavity of the installation seat, and the other end of the power supply extends into the cavity of the radiator, is suspended above the light source piece and is not contacted with the radiator. According to the LED bulb lamp, the damage to a light source and the power supply due to the thermal polymerization of the power supply and the light source is prevented, the separation and respective heat dissipation of the light source and the power supply are realized, and the service life of the light source and the power supply is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to an LED bulb lamp. Background technique [0002] With the continuous increase of LED light efficiency and the reduction of cost, LED lighting has increasingly become a perfect substitute for incandescent and fluorescent lamps. For an LED bulb, the most important thing is the light source, driving power and cooling device. Usually, an LED bulb lamp is provided with a lamp holder, a driving power supply, a heat sink, a light source and an optical lens from top to bottom. Wherein, the light source and the driving power are usually separated by structures such as partitions and boxes. [0003] For example, the Chinese patent document CN202253062U discloses a high-power LED industrial lighting bulb, a screw-type lamp cap, a lamp cap interface piece, a cross-current drive power supply, a power supply box, a lamp body radiator, a high-power LED mounting plate, a high-power LE...
