Abstract

The invention discloses a high-power integrated LED (light-emitting diode) lamp body structure with a micro lens array. The lamp body structure provided by the invention comprises a high-power integrated LED light source, wherein at least two or more than two GaN (gallium nitride)-based blue light chips are arranged in the light source in accordance with the configuration manner of the array; the upper parts of the chips are coated with YAG (yttrium aluminum garnet) yellow phosphor powders, and encapsulated by a silica gel; and the micro lens array formed by the plural micro lenses of which the number is equal to that of the blue light chips is arranged above the high-power integrated LED light source, and each micro lens in the micro lens array corresponds to each blue light chip in the LED light source one to one. The lamp body structure provided by the invention has the advantages of overcoming the defects of the prior art and solving the problem that the yellow circles at edges of the LED lighting is hard to overcome under the condition of large lenses.

Description

Technical field: [0001] The invention relates to the technical field of semiconductor lighting and LED secondary light distribution, in particular to a high-power integrated LED lamp body structure using a microlens array. Background technique: [0002] At present, LEDs are divided into low-power LEDs and power-type LEDs. Among them, those with input power below tens of milliwatts belong to low-power LEDs; while power-type LEDs are divided into two types: ordinary power LEDs and W-level power LEDs, and the input power is greater than or equal to 1W LEDs are W class power LEDs (high power LEDs). With the continuous improvement of LED light efficiency and LED manufacturing technology, high-power LED lights have begun to get better and better in street lights, tunnel lights, high pole lights, flood lights, explosion-proof lights, spotlights, landscape lights, and special lights. more and more widely used. High-power LED lights have significant advantages such as high luminous...
