Abstract

The invention relates to an improvement of a light-emitting diode (LED) module and a lighting fixture structure, wherein the LED module comprises a base, a reflector, a diffuser and a fluorescent glue layer. The base is provided with an accommodating part for accommodating at least one LED wafer, the reflector is arranged on the base, is provided with an accommodating space for accommodating a first colloid, and the diffuser is in butt joint with the reflector for sealing the first colloid, and the fluorescent glue layer is arranged between the diffuser and the first colloid. Through the structural design provided by the invention, more uniform light spots and color temperatures can be effectively realized, and moreover, the integral emergent optical efficiency is effectively improved.

Description

technical field [0001] The invention relates to an LED lamp structure, in particular to an improved LED module and a lamp structure which can achieve more uniform light spot and color temperature, and further effectively improve (or enhance) the overall light output efficiency. Background technique [0002] In recent years, with the rapid development of light-emitting diodes (LEDs), the luminous efficiency (or luminous efficiency) of LEDs has surpassed that of traditional energy-saving light sources; thus, high-power LED lights have been widely used in indoor and outdoor lighting and other fields. [0003] Currently, the LED lights on the market are usually composed of dozens or hundreds of high-power 1W LEDs combined to form an LED module to achieve the required luminous flux and brightness, but the size of the LED module in this way is relatively large. , if the above-mentioned LED module is applied to close-range lighting, it is easy to cause multiple shadows on the illum...
