Description

A high heat dissipation LED bulb lamp

technical field

The utility model relates to the field of lamp lighting, in particular to an LED bulb lamp with high heat dissipation.

From incandescent lamps to fluorescent lamps to LED lamps, the many advantages of LED lamps make them widely used in daily life. Street lamps, household lamps, table lamps, etc. Great convenience, LED lamp technology is advancing with each passing day, and its luminous efficiency is making an amazing breakthrough. Reduced, but even LED lamps with extremely low energy consumption still generate heat. Although LED lamps have always been claimed as cold light sources, many consumers think that LED lamps do not generate heat like incandescent lamps. In fact, this is wrong, and LED lamps still It will generate heat. There is no technology that can convert electric energy 100% into light energy, and there will always be losses. The electric energy liquid input by the LED lamp is not completely converted into light energy, and some of it is converted into heat energy, so heat is generated. For example, only 20%-30% of the electric energy of the LED bulbs we use every day is converted into light, and the other 70% is converted into heat energy. If the heat dissipation of the LED bulbs is not good, it will make the LED lamp beads. The junction temperature of the LED bulb increases rapidly. If the LED bulb is in a high temperature state for a long time, the life of the LED bulb will be shortened. Therefore, all LED bulb manufacturers are trying to solve the problem of heat dissipation of the LED bulb to prolong the LED bulb. The service life of the bulb lamp is limited, so we are looking for a high heat dissipation LED bulb lamp to make up for the deficiencies of the products currently on the market.
