The invention relates to the technical field of cooling, and in particular to an illumination device. The illumination device comprises a cooler and circuit board. The cooler comprises a base, a first substrate, a second substrate and a plurality of cooling columns. The first substrate and the second substrate are connected and arranged on the same side face of the base. The cooling columns are arranged on the first substrate and the second substrate. Installation areas are arranged on the first substrate and the second substrate. The circuit boards are fixedly arranged on the installation areas. According to the illumination device, the first substrate and the second substrate are arranged on the base; the base can play a fixing and limiting role and is used for fixing the substrates to the base; and heat generated by electronic elements can be conducted to the outside through the substrates. In addition, the cooling columns are arranged on the first substrate and the second substrate, heat is conducted to the cooling columns from the substrates and is dispersed to air through the cooling columns, and therefore rapid transmitting and dispersing of heat are facilitated, and the cooling performance of the illumination device is effectively improved.
Description
technical field [0001] The invention relates to the technical field of heat dissipation, in particular to an illuminating device. Background technique [0002] LED is the abbreviation of light emitting diode in English. Its basic structure 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 circuit board with silver or gold wires. , and then sealed with epoxy resin around it to protect the inner core wire, and finally install the shell, so the LED lamp has good shock resistance, and is called the fourth generation of green light source. [0003] LED lighting is a lighting fixture made of the fourth-generation green light source LED, that is, LED is called the fourth-generation lighting source or green light source. It has the characteristics of energy saving, environmental protection, long life, and small size. Various indications, displays, decorations, backlights, general li...
