LED lamp module with light distribution on internal surface

Abstract

The invention relates to a light emitting diode (LED) lamp module with light distribution on the internal surface. The LED lamp module consists of an internal curved light distribution lens, an aluminium alloy shell, an LED light source, a printed circuit board (PCB), a water-proof joint and a water-proof rubber ring, wherein the LED light source is welded on the PCB board; the PCB board and the water-proof joint are fixed on the aluminium alloy shell; and the internal curved light distribution lens presses the water-proof rubber ring on the aluminium alloy shell. The outer surface of the internal curved light distribution lens is a plane or is a plane approximately with a relatively big curvature; and the inner side of the internal curved light distribution lens is a free curved surface array consisting of a plurality of light distribution units. Because the light distribution units are integrated and the outer surface is a plane or is a plane approximately, the utilization of water-proof and dust-proof plate glass is reduced; the reflection loss is reduced; the light emitting efficiency is high; and the energy utilization rate can be improved. The LED lamp module is applied to road illumination, tunnel illumination, floodlight illumination and indoor illumination in parking lots, factory workshops and the like.

Description

technical field [0001] The invention relates to an LED lamp module with light distribution on the inner surface. Background technique [0002] With the rapid growth of the world economy, the global energy shortage is becoming more and more serious. The call for energy saving and emission reduction and seeking a low-carbon development model is getting louder and louder. As far as lighting is concerned, its electricity consumption accounts for 20% of the total electricity consumption in the world. Under this background, the energy-saving and high-efficiency solid-state lighting source - the technology of light-emitting diode LED continues to improve, and its light efficiency continues to rise, and it has begun to be gradually applied in the field of lighting and display. The application of road lighting has attracted much attention. The Ministry of Science and Technology launched the "ten cities and ten thousand lamps" semiconductor lighting demonstration project to push LE...

Problems solved by technology

However, if the light source of the traditional sodium lamp is damaged, the problem can be solved in 5 minutes. If the light source is broken, the lamp can still be used continuously.

Moreover, the dimensions and power of different manufacturers are inconsistent, which means that the versatility of LED street lights is poor. If you purchase a weak manufacturer, you will not be able to find parts for future maintenance.
