When the LED lamp is used in daily life, the LED lamp with higher power has larger unit heat productivity due to the integration of a plurality of LED lamp beads, and the service life of the bulb is seriously influenced by the accumulation of a large amount of heat.
On the other hand, plastic-coated aluminum is a heat dissipation mode of an LED lamp, the aluminum heat conductor is wrapped by high-thermal-conductivity plastic, the heat conductor conducts heat, the plastic dissipates heat, the cost is lower than that of a pure aluminum radiator, the plastic-coated aluminum is mainly used for LED lamps in low-end markets at present, but the heat dissipation performance of the plastic-coated aluminum is much lower than that of the pure aluminum radiator, LED chips are frequently damaged due to poor heat dissipation performance and high internal temperature, and the plastic-coated aluminum is suspected by customers though the low-end markets are mainly played; the first plastic-coated aluminum mostly adopts a closed funnel-shaped plastic shell to completely wrap the heat conductor, the heat conductor with high heat conductivity coefficient only plays a role in heat conduction, heat dissipation completely depends on high-heat-conductivity plastic, and the plastic-coated aluminum mode has extremely poor heat dissipation performance.
Disclosure of Invention
Not enough to prior art exists, the utility model aims to provide a novel heat dissipation LED bulb has better heat dispersion, can prevent that the base plate high temperature and lead to ageing and the fusing of components and parts to prolong the life of lamps and lanterns.
In order to solve the technical problem, the utility model provides a novel heat dissipation LED bulb, including the heat conduction heat accumulation post the top heat conduction face of heat conduction heat accumulation post is provided with welded LED lamp pearl circuit board, and the shaft is provided with 2 at least ring form fin, and bottom opening part inner chamber is provided with drive power supply, drive power supply with welded LED lamp pearl circuit board electricity is connected.
As a further aspect of the present invention: the welded LED lamp bead circuit board is provided with a square hole, the square hole is buckled and is connected with an optical lampshade to form a whole, and the second square hole arranged on the heat conduction and heat storage column is buckled on the decorative plastic lamp body.
As a further aspect of the present invention: the appearance surface of the decorative plastic lamp body is provided with at least one convection hole, and the bottom of the decorative plastic lamp body is provided with a threaded lamp cap.
As a further aspect of the present invention: the annular radiating fins are made of aluminum alloy through a stamping and stretching process, are respectively arranged on the column bodies of the heat conduction and storage columns in a staggered mode and are tightly matched with the column bodies.
As a further aspect of the present invention: the welded LED lamp bead circuit board is composed of LED lamp beads and a circuit aluminum substrate, and the LED lamp beads are attached to lamp bead bonding pads corresponding to the circuit aluminum substrate through an SMT chip mounter.
As a further aspect of the present invention: at least 2 fins are arranged on the annular radiating fin, and the thickness of each fin is 0.5-1.5 mm.
In conclusion, the beneficial effects of the utility model are that: the shaft through heat conduction heat accumulation post is provided with 2 at least ring shape fin, is provided with at least one convection hole simultaneously at the outward appearance face of decorating the plastics lamp body, can effectually accelerate the air flow, takes away the heat that LED lamp pearl during operation produced, has improved heat dispersion greatly, has prolonged the life of lamps and lanterns.
