Abstract

The invention provides a high-density packaged light-emitting diode (LED) desk lamp. The high-density packaged LED desk lamp comprises a lamp holder, wherein not less than 6 LED chip modules are packaged in each 7mm unit area of a lamp holder bottom plate; 120 LED chip modules are packaged on the 140mm lamp holder bottom plate; and the LED desk lamp is connected with a 15W12V low-voltage external constant current power supply. The whole desk lamp is made of an aluminum alloy material and can radiate high-density packaged LEDs to avoid the light attenuation of the LEDs; the high-density packaged LEDs are adopted, so the whole high-density packaged LED desk lamp has small volume and is energy-saving and environment-friendly; the desk lamp has a dimming function and can realize stepless dimming in the range of 0 to 100 percent; and the LED desk lamp does not have stroboflash and has the function of protecting eyes.

Description

technical field [0001] The invention relates to the technical field of semiconductor lighting, in particular to a desk lamp, in particular to a high-density packaged LED desk lamp. Background technique [0002] Existing desk lamp, its light source mainly is based on incandescent lamp and cold cathode lamp tube. This type of desk lamp has the advantages of low cost and good color rendering; but the disadvantage is that it will produce stroboscopic flicker when used, and high heat will be generated after long-term use, which will shorten its life, so the service cycle will also be shortened. [0003] Light-emitting diodes (LEDs) The so-called LED lamps, as the name suggests, refer to lamps and lanterns that use LED (Light-emitting Diode, light-emitting diode) technology as the main light-emitting source. LED is a solid-state semiconductor component, which uses current to flow forward to the semiconductor p-n junction coupling, and then the negatively charged electrons and pos...
