Abstract

An illumination lamp comprises a mounting module, an LED module, a heat radiation module, a fixed base and a reinforcement heat radiation piece. The heat radiation module comprises a heat radiation mainboard body, a heat radiation assembly and two heat radiation columns. The first end and the second mounting face of the heat radiation mainboard body are fixed. The heat radiation assembly comprises a plurality of first cooling fins and a plurality of second cooling fins. The heat radiation module of the illumination lamp is provided with the heat radiation mainboard body, the heat radiation assembly and the two heat radiation columns, and therefore heat transmitted to the mounting module from the LED module can be fast radiated to the outside in time; and the mounting module and the fixed base can achieve the function of assisting in heat radiation, and therefore the heat radiation effect can be improved so as to meet the requirement of the lamp with the high heating value.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a lighting fixture. Background technique [0002] Usually, the existing lamps generally install the light-emitting components on the aluminum substrate, and then install the aluminum substrate on the housing of the lamp. The heat generated by the light-emitting components during normal lighting needs to be transferred to the aluminum substrate, and then transferred through the shell. to the outside air to achieve cooling effect. [0003] However, limited by the structure of the aluminum substrate, its heat dissipation effect is limited, and it is difficult to meet the requirements of high-power, high-brightness and high-heating lamps. Furthermore, the shell of the lamp is usually made of plastic, and its heat dissipation performance is poor. More The ground plays the role of protection and decoration, but it will affect the heat dissipation path between the aluminum sub...

[0003] However, limited by the structure of the aluminum substrate, its heat dissipation effect is limited, and it is difficult to meet the requirements of high-power, high-brightness and high-heating lamps. Furthermore, the shell of the lamp is usually made of plastic, and its heat dissipation performance is poor. More The ground plays the role of protection and decoration, but it will affect the heat dissipation path between the aluminum substrate and the outside air, and the heat dissipation effect is poor, especially difficult to meet the requirements of high-power, high-brightness and high-heat-generating lamps.
