Description

A kind of LED lamp with double cooling system

technical field

The utility model relates to the field of LED lamps, in particular to an LED lamp with a double heat dissipation system capable of conducting heat conduction and heat dissipation on a light-emitting panel and a driving part at the same time.

Background technique

LED lamps are one of the most commonly used lamps on the market. Compared with other types of lamps, LED lamps have higher luminous efficiency, and the power consumption is as low as one ten thousandth of incandescent lamps and half of fluorescent tubes. One, the service life is longer than that of incandescent lamps, fluorescent lamps and halogen tungsten lamps, it has strong reliability, low calorific value, no heat radiation, it can be safely touched by using cold light source, and has better mechanical properties, recyclable and pollution-free, etc. Therefore, the usage of incandescent lamps is huge.

However, with the needs of technology and market development, each driver of the LED filament lamp bulb has been assembled inside the lamp head to achieve no plastic parts. The original sheath between the LED drive power supply and the metal lamp cap is only a simple insulation function, which can no longer meet the heat dissipation requirements of the drive. In the case of poor heat dissipation, the temperature of the LED drive power supply will rise, which will greatly reduce its temperature. Power supply efficiency and performance, and under the conditions of long-term high temperature and poor heat dissipation, all parts of the LED drive power supply are prone to oxidation and aging, which reduces its service life.

On February 6, 2013, the Chinese Patent Office published an authorization document for a heat-dissipating LED lamp. The authorization announcement number is CN202719443U. To form a convection heat dissipation system to dissipate heat from the LED lamp, but if it is used for a long time, the heat of the LED lamp will gradually spread to the outside of the lamp, and a layer of hot air will be surrounded outside the lamp, resulting in weakened convection effect and convection effect It will have a direct impact on its heat dissipation effect, and due to the setting of the convection cavity, convection port and convection groove, it will have a certain impact on the sealing of the lamp. Convection is easy to bring dust into the lamp, which is easy to cause aging damage to the lamp.
