Embodiment Construction
[0032] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0033] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

The invention relates to a lamp. The lamp comprises a carrying tray, a supporting rack, a liquid storage ball, an air extraction assembly, an air-blowing assembly, an air-blowing pipe, an exhaust pipe, an auxiliary lighting assembly and an LED module, wherein the supporting rack is arranged on the carrying tray; the liquid storage ball is arranged on the supporting rack; the air extraction assembly is arranged on the liquid storage ball; the air-blowing assembly is arranged on the air extraction assembly; the air-blowing pipe is separately connected to the air-blowing assembly and the liquid storage ball; the exhaust pipe is arranged on the liquid storage ball; the LED module is arranged on the air extraction assembly; the auxiliary lighting assembly comprises a cover body and a plurality of auxiliary lighting sub light sources; the cover body is hollow and communicates with the second end of the exhaust pipe; and a plurality of exhaust holes are formed on a side face, far away from the exhaust pipe, of the cover body. Air in the exhaust pipe of the lamp is maintained in a continuous circulating state under the action of a fan. When heat quantity generated by normal work of the LED module is transferred to the exhaust pipe, the continuous circulating air in the exhaust pipe can quickly and immediately take away heat quantity generated by normal work of the LED module, so that the lamp is relatively good in radiating performance.
Description
technical field [0001] The invention relates to the technical field of lamps, in particular to a desk lamp. Background technique [0002] At present, in the existing lighting equipment, its main heat dissipation components include the PCB aluminum substrate in direct contact with the light source, and the circuit board that drives the light source to emit light, that is, the heat generated when the light source emits light is dissipated by the PCB aluminum substrate and the circuit board. . [0003] With the design trend of lighting equipment integration, most manufacturers usually install PCB aluminum substrate and circuit board inside the lighting equipment. [0004] Among them, the PCB aluminum substrate and the circuit board generally transfer heat to the air through the housing. However, the illuminating device adopting the above-mentioned structure for heat dissipation still has the defect of poor heat dissipation performance. Contents of the invention [0005] Ba...
