Integrated LED (light emitting diode) module with thin fly's-eye lens

Abstract

The invention discloses an integrated LED (light emitting diode) module with a thin fly's-eye lens. The LED module comprises LED chips, a golden wire, a positive electrode, a negative electrode, a substrate, fluorescent glue, transparent silica gel, a thin fly's-eye lens, a reflection cup pressing plate and a fixed pressing ring; the reflection cup pressing plate is arranged on the substrate and defines a cavity; a plurality of chips are arranged into an array and are, fixed on the substrate and are positioned in the cavity defined by the reflection cup pressing plate; the LED chips are connected together through the golden wire and connected to the positive electrode and the negative electrode; the LED chips are coated with fluorescent glue; the thin fly's-eye lens is installed on the reflection cup pressing plate or the substrate through the fixed pressing ring; and the transparent silica gel fully fills a space defined by the thin fly's-eye lens, the reflection cup pressing plate and the fluorescent glue. According to the invention, based on the ultrathin property of the thin fly's-eye lens, the thin fly's-eye lens is directly installed on the LED integrated module, the installation of the thin fly's-eye lens is convenient, good heat dissipation of the module can be achieved, the effect of less optical loss is reached, the LED lighting effect is improved, and the reliability and service life are increased.

Description

technical field [0001] The invention relates to an integrated LED module with a thin fly-eye lens, in particular to an integrated LED module with a thin fly-eye lens. Background technique [0002] In recent years, energy saving and environmental protection, and creating a low-carbon society have become the basic policies of countries all over the world. As a new generation of green lighting sources, LED light sources have shown incomparable excellent characteristics of traditional light sources in terms of energy saving and environmental protection. With the continuous improvement of the luminous efficiency of LED, the application of LED is becoming more and more extensive, showing incomparable advantages in terms of energy saving. The cooling of the LED during operation is crucial to the light output efficiency and life of the LED, which puts forward high requirements on the heat dissipation performance of the LED. [0003] At present, the packaging of general LED integrat...

Problems solved by technology

However, on the packaging side, since the free-form surface lens is directly buckled, there will be a certain air layer during the period, so that the heat dissipation cannot be solved well, and it cannot be effectively waterproofed so as to affect the light distribution stability and use. life

Furthermore, because the lens itself is relatively thick, the cost is high, the loss of light in the lens is large, and the light distribution is single, and such a thick lens greatly hinders the heat dissipation of the LED.

Therefore, this packaging method has certain limitations in practical applications.
