Description

technical field [0001] The invention relates to an LED energy-saving lamp, in particular to a long-life LED energy-saving lamp. Background technique [0002] Existing LED energy-saving lamps save energy significantly, but the manufacturing cost is high, and the price is many times higher than that of ordinary lamps; LED energy-saving lamps generate a lot of heat when they work, and their working principle makes the problem of heat dissipation very prominent. It is easy to burn out its drive power (transformation) components, LED chips and other components, which increases the cost of using LED energy-saving lamps. Therefore, simplifying the structure of LED energy-saving lamps, reducing manufacturing costs, solving heat dissipation problems, and prolonging the life of LED energy-saving lamps are the key to improving the market competitiveness and practicability of LED energy-saving lamps.

AI Technical Summary

Problems solved by technology

[0003] The LED chip of the existing LED energy-saving lamp is installed on the LED chip board, and the LED chip board is connected and fixed with the heat transfer plate, and the heat transfer plate is connected and fixed with the end of the heat sink, that is, the LED chip is indirectly connected through the LED chip board. The ground is connected to the heat transfer plate, and the large amount of heat accumulated at the bottom of the LED chip will be conducted to the heat transfer plate through the LED chip board, and then dissipated through the heat sink, and the heat sinks of the existing LED energy-saving lamps are connected to each other through one side of each heat sink. Directly connected as a whole, the air cannot cross the entire heat sink from one side of the heat sink and then radiate from the other side, that is, each heat sink forms a sealed cavity in the middle, and the radial (transverse) direction of the cavity is sealed. Only the upper and lower openings, the cavity and the heat dissipation gaps between the heat sinks are not connected, the air cannot cross out from the cavity and then radiate out through the gaps between the surrounding heat sinks, that is, the air cannot pass through horizontally. Convection

[0004] The disadvantages of the above-mentioned structure of the existing LED energy-saving lamps are that the structure is complex, the manufacturing cost is high, the price is high, the heat dissipation is not smooth during use, the accumulated temperature in the middle is high, and it is easy to burn out the drive power (transformer) components, LED chips and other components. short, expensive to use
