Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a lamp. Background Art

[0002] LED lamps are widely used in lighting for various scenarios due to their high luminous efficiency, long life, low power consumption, good weather resistance and other characteristics that are superior to traditional light sources. Since LED lamps generate a lot of heat during operation, heat dissipation devices are usually installed on LED lamps to prevent the temperature of the LED lamps from being too high and causing damage to the LED lamp chips. When LED lamps work in a high temperature environment, such as for internal lighting of kitchen appliances such as steamers, ovens or air fryers, the heat dissipation performance of the LED lamps themselves will be greatly reduced because the temperature of the working environment will reach 350°C or above and the ventilation is poor. The heat generated during the operation of the LED lamps cannot be dissipated, which will shorten the service life of the LED lamps, resulting in frequent replacement of LED lamps and poor user experience.
