LED (light-emitting diode) module

Abstract

The invention relates to an LED (light-emitting diode) module which comprises a radiator, a lens module fixed on the radiator, and an LED integrated light source which is fixed on the radiator and contained in the lens module; the radiator comprises a mounting plate; the lens module comprises a waterproof sealing ring, a waterproof packing ring and a lens gland which are sequentially laminated onthe mounting plate; and the waterproof sealing ring and the lens gland holds and fixes the lens and the waterproof packing ring onto the mounting plate. The light distribution form of the lens adoptscut-off, Class II, short-projection light distribution or medium-projection light distribution; the C0 surface is designed as symmetrical bat wing light distribution, and the maximum light intensity angle is 60-65 degrees; and the C90 surface is designed as asymmetric light distribution, and the maximum light intensity angle is 15-30 degrees. The LED module has a simple structure, can satisfy requirements for different occasions, can be directly used in traditional lamp shells, and thus, has wide applicability.

Description

technical field [0001] The invention relates to a lighting device, in particular to an LED module. Background technique [0002] Due to the continuous development of LED lighting technology, LED is not limited to indoor lighting, and outdoor lighting has gradually become the research field of various LED lighting companies. Because LED has the characteristics of high luminous efficiency, low reflection loss of lamps and lanterns, energy saving, etc.; with digital control brightness function, it can save more power; low voltage, high safety and other advantages, many LED lighting enterprises are turning their attention to LED street lamps, floodlights, tunnels Lights and high bay lights and other fields. [0003] For LED outdoor lighting currently on the market, the radiators used by various types of lamps are not the same and cannot be interchanged.

AI Technical Summary

Problems solved by technology

[0003] For LED outdoor lighting currently on the market, the radiators used by various types of lamps are not the same and cannot be interchanged.

As far as street lights are concerned, most of them use a single 1W LED chip with a huge die-casting aluminum radiator; while floodlights mostly use integrated light sources or a single 1W light source with a die-cast aluminum radiator, which is smaller than street lights. It is much smaller; tunnel lights and industrial and mining lights mostly use sunflower radiators, which are used with integrated light sources; at the same time, street lights and floodlights have to replace traditional lamp shells, resulting in a certain degree of waste. High cost and long cycle

To sum up, as far as the current LED outdoor lighting fixtures are concerned, they cannot be interchanged, and the radiators need to be redesigned, which cannot be compatible with traditional lamps.
