Problems solved by technology

However, due to the reflection of the light on the light-emitting surface of the lens, part of the light is emitted from the bottom or side of the lens, resulting in that this part of the light is not used and wasted

Embodiment Construction

[0013] see figure 1 and figure 2 , the LED module 1 of the present invention includes a LED 10 and a lens 40 matched with the LED 10 .

[0014] The light emitting diode 10 includes a flat substrate 11, a first electrode 12 and a second electrode 13 located on the upper surface of the substrate 11 and arranged at intervals, and located on the first electrode 12 and connected to the first electrode 12 and the second electrode 13. An LED chip 20 electrically connected to the two electrodes 13 .

[0015] The lens 40 accommodates the LED chip 20 therein, and is used to change the light output path of the LED 10 , so as to improve the light utilization efficiency of the LED 10 . In order to prevent the LED chip 20 from being damaged, a transparent encapsulation 31 is disposed on the substrate 11 and surrounds the LED chip 20 . Certainly, in the above-mentioned embodiment, required fluorescent powder 32 may be further arranged in the enclosure 31, so as to obtain light of differe...

Abstract

A light emitting diode module comprises a light emitting diode chip and a lens matched with the light emitting diode chip. The lens comprises a light guide part and a rough structure, wherein the light guide part is provided with a hole, the rough structure is convexly arranged from the light guide part, the light guide part has a top surface, the area where the top surface is located is an effective illumination area of the light emitting diode, the light emitting diode chip is accommodated in the hole, and light emitted by the light emitting diode chip is emitted out from the top surface of the light guide part after being reflected back to the lens from the top surface and reflected and refracted through the rough structure.

Description

technical field [0001] The invention relates to a semiconductor structure, in particular to a light emitting diode light source. Background technique [0002] As a high-efficiency light source, light-emitting diodes have many characteristics such as environmental protection, power saving, and long life, and have been widely used in various fields. [0003] The light emitting angle of most light-emitting diodes is generally 90 degrees to 120 degrees. The light intensity in the center of the light emitting angle (the light emitting angle is about 0 degree to 30 degrees) is stronger, and the surrounding light intensity is weaker, and the light intensity in the center of the light emitting angle is stronger. It is acceptable for the light to be used for lighting, but the surrounding light with weak intensity cannot meet the requirements of lighting, thus forming a waste of light and reducing the light utilization rate of LEDs. For this reason, the industry uses a lens to adjust...
