Concentrating lens optical module

Abstract

The invention discloses a condensation type lens optical module which is suitable for conducting condensation on light rays emitted by an LED chip of an LED mining lamp. The condensation type lens optical module comprises a lens and a light reflection bowl, wherein the light reflection bowl and the lens are arranged in an opposite mode to form a containing cavity used for containing the light-emitting face of the LED chip, the light reflection bowl is provided with a light refection face facing towards the containing cavity, an outward-protruding light input face is arranged at the bottom of the lens, the light input face faces toward the light-emitting face of the LED chip and corresponds to the light-emitting face, and an outward-protruding light output face is arranged at the top end of the lens. The condensation type lens optical module is high in condensation capacity and good in condensation effect, and therefore the overall luminous efficiency of the LED mining lamp of the condensation type lens optical module is extremely high.

Description

technical field [0001] The invention relates to a concentrating lens optical module, in particular to a concentrating lens optical module for concentrating light emitted by an LED chip of an LED industrial and mining lamp. Background technique [0002] With the continuous development of the economy and the continuous progress of the society, the consumption of resources is accelerated, resulting in a shortage of resources, and correspondingly restricts the pace of economic development and social progress. Therefore, energy conservation has become one of the important goals that enterprises are concerned about. [0003] Among them, in the field of lighting, due to the defects of high energy consumption, short life and non-environmental protection of traditional Wusi lamps, it creates good conditions for the development of new energy-saving lamps, and LED lamps are based on the above conditions. Yes, because LED lamps have the advantages of energy saving, environmental protect...

Problems solved by technology

However, in the existing lens structure, the side of the lens close to the light-emitting surface of the LED chip is designed as a concave curved surface, and the side of the lens away from the light-emitting surface of the LED chip is designed as a convex curved surface. The change of the curve of the outer surface can be used to design the lens. At the same time, the concave surface will reduce the light-gathering effect of the existing lens, resulting in extremely poor light-gathering ability of the existing lens. Therefore, the optical module formed by the lens and the reflector The light-gathering ability is extremely poor, and the light-gathering effect is not good, so that the overall luminous efficiency of LED high bay lights is not high
