Problems solved by technology

[0003] The present invention solves the problem that the heat dissipation structure of the existing LED lighting products has a poor heat dissipation effect on the LED chip, and the heat dissipation is not timely, the heat dissipation effect is poor, and it is easy to cause the temperature of the LED chip of the lamp to be too high and burn out the chip. The service life of the LED chip is shortened, and ultimately the service life and performance of the entire LED energy-saving lamp are reduced. The current situation provides a method that can improve the heat dissipation effect of the LED chip to a greater extent, and achieve the goal of improving the working performance and service life of the LED chip. Heat dissipation structure of LED lamp and LED energy-saving lamp adopting the heat dissipation structure

Abstract

The invention discloses an LED lamp heat dissipation structure and an LED energy-saving lamp with the same. A first heat dissipation component is an outer side heat dissipation component of the LED lamp heat dissipation structure, and a second heat dissipation component is an inner side heat dissipation component of the LED lamp heat dissipation structure; a plurality of protruding second heat dissipation fins are distributed on the outer side face of the second heat dissipation component in a connected mode, the first heat dissipation component is arranged on the outer side of the second heat dissipation component in a connected mode, a plurality of protruding first heat dissipation fins are distributed on the inner side face and the outer side face of the body of the first heat dissipation component in a connected mode, and heat dissipation height separation space where heat generated when an LED chip works is rapidly conducted to the second heat dissipation component and radiated in convective air is reserved between the bottom end of the inverted first heat dissipation component and the outer side of the second heat dissipation component. The LED lamp heat dissipation structure has sufficient heat dissipation areas, has more heat dissipation areas than a conventional heat dissipation aluminum piece, has more convective air mass flow, can rapidly produce cross ventilation of an inner cavity and an outer cavity of the heat dissipation aluminum piece, and reaches the effect that the heat is rapidly scattered.
