Problems solved by technology

Therefore, when the LED light source changes, the secondary or multiple optical control devices designed for a certain LED cannot continue to be used. The secondary or multiple optical control devices have poor versatility and need to be redesigned and manufactured for secondary or multiple times Optical control devices, which greatly increase the cost of LED lighting devices, limiting the wide application of LEDs
[0005] In addition, due to the concentrated optical output of the LED light source, the surface brightness of the LED lighting device is very high, which makes the user feel very dazzling, and the glare is strong, which also restricts the wide application of LED

Abstract

The invention provides an LED (Light Emitting Diode) illuminating device with a micro-structure optical film. The LED illuminating device comprises a shell (1), a printed circuit board (3), at least one LED chip (2), an LED driving power supply and a cover (4), wherein the printed circuit board (3) is arranged in the shell (1); the LED chip (2) is arranged on the printed circuit board (3); the LED driving power supply is electrically connected with the LED chip (2); the cover (4) is used for packaging the LED chip in the shell (1); the LED illuminating device is characterized by further comprising the micro-structure optical film (5) arranged on the upper surface of the cover (4); the micro-structure optical film (5) is used for controlling the optical output of the LED light source so as to meet an illuminating demand of a specific application scene; the micro-structure optical film is utilized to adjust the concentrated optical output of the LED light source, so that the glare condition is effectively improved while the illuminating light distribution is met.

Description

technical field [0001] The invention relates to an LED lighting device, in particular to an LED lighting device with a microstructure optical film. Background technique [0002] Semiconductor photodiodes (LEDs, Light Emitting Diodes), as a new energy-saving and environmentally friendly light source, are more and more widely used in general lighting environments. Existing LEDs for lighting applications have the brightness, efficiency, service life, color temperature, and white point stability required for general lighting. As a result, these LEDs are used in the design of most general lighting applications, including pavement, parking areas, and indoor directional lighting. In these applications, LED-based lighting fixtures reduce the total cost of ownership (TCO) due to no maintenance (LEDs last much longer than conventional light bulbs) and low energy consumption. Illumination-grade LEDs have at least 50,000 hours of efficient, directional illumination. The lighting syst...
