LED lamp with efficient heat dissipation function and air purification function

Abstract

The invention discloses an LED lamp with an efficient heat dissipation function and an air purification function. The LED lamp comprises a mounting plate, a heat dissipation cavity and a fan, the heatdissipation cavity is formed below the mounting plate, and the fan is arranged above the mounting plate; an LED driver is arranged in the heat dissipation cavity, an LED substrate is arranged below the LED driver, and the heat dissipation fins are fixedly connected to the upper surface of the LED substrate. The LED lamp beads are electrically connected to the lower portion of the LED substrate, afirst filtering tank is connected to one side of the heat dissipation cavity through an air conveying pipe, and a second filtering tank is connected to the other side of the heat dissipation cavity through an air conveying pipe. The LED lamp is simple in structure and novel in design, a set of complete air circulation can be formed through the cooperation of the fan and an air outlet, the heat generated during operation of the LED lamp can be effectively dissipated, and the poor light of the lamp due to internal overheating is prevented, so that the working efficiency of the LED lamp is improved, the service life of the LED lamp is prolonged, and the LED lamp has the very good popularization value.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp with efficient heat dissipation and air purification function. Background technique [0002] At present, the LED is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connected to the chip and the circuit board with silver or gold wires, and then sealed with epoxy resin around it to protect the inner core. The role of the wire, and finally install the shell, so the shock resistance of the LED lamp is good. The field of application involves mobile phones, table lamps, home appliances and other daily household appliances and machinery production. [0003] However, when the LED lamp is working, about 80% of the electrical energy will be converted into heat energy, and 20% of the electrical energy will be converted into light energy, because when the LED chip is working, its own ambient temperature is inversely proporti...

[0003] However, when the LED lamp is working, about 80% of the electrical energy will be converted into heat energy, and 20% of the electrical energy will be converted into light energy, because when the LED chip is working, its own ambient temperature is inversely proportional to the light output rate. The higher the value, the lower the light output rate. When the temperature reaches the maximum operating temperature of the LED chip, the LED will be broken
