Description
Technical field
The invention belongs to field of semiconductor illumination, be specifically related to a kind of LED light engine.
Background technology
LED light Engine, i.e. LED light engine, refer to and comprise the entire combination that LED encapsulates (element) or LED array (module), LED driver and other luminosity, calorifics, machinery and electrical equipment, this is combined through an ordinary connector mated with LED lamp and is directly connected on branch circuit, therefore, LED photo engine is a device between LED light fixture and LED lamp, it not only effectively can improve the stability of LED lamp, can also improve the performance such as colour rendering and system light efficiency of LED lamp.The advantages such as along with the development of LED technology, increasing LED light engine is applied to lighting field, and it specular removal possessed, long-life, energy-conserving and environment-protective and volume are little, determine the main flow lighting source that it will become a new generation.
The LED light engine generally used in the market, be formed by combining by Combined lens, the circuit board being welded with lamp pearl, sealing solid silica gel and liquid-state silicon gel, radiator mostly, the circuit board being about to be welded with LED lamp bead is arranged on the radiator of LED light engine, simultaneously, between radiator and circuit board, filling liquid silicone grease carries out heat conduction, and radiator is placed in the main body of Combined lens, the lens unit on Combined lens is arranged on the periphery of lamp pearl; Mainly there is following defect in the LED light engine of this structure:
(1) in Combined lens, because each lens is all convex, when the light-emitting area of LED light engine is arranged down, or being assembled in the process in light fixture, lens directly contact with the face of shelving or light fixture, therefore, be easy to be squeezed or rub, cause protruding lens surface to be scratched, thus affect the overall light-out effect of LED light engine, affect the illuminating effect of road further;
(2) in the Combined lens assembling process of radiator and LED light engine, need slightly to apply pressure to radiator, now liquid-state silicon gel can overflow between radiator and lens, and spill portion branch is attached on the outer surface of radiator or lens, need manually to carry out wiping, thus add operation, waste time and energy, reduce production efficiency; Simultaneously, liquid-state silicon gel is after spilling between radiator and lens, decrease the liquid-state silicon gel amount for adhering and sealing, for the layer of silica gel between radiator and lens, the silica gel of its surrounding in the curing process, because volume diminishes gradually, therefore can form space between radiator and lens, thus cause the integral sealing effect of LED light engine to be deteriorated.
(3) light is reflected by two kinds of different mediums, also reflects simultaneously.The light that LED lamp bead sends is by the silica-gel lens of self, and then by after the air in the confined space between Combined lens and radiator, then through independently lens unit on Combined lens, its material is PC; Because the refractive index difference of silica gel, PC and air is comparatively large, after twice refraction, reflection, causes the light emission rate of LED lamp bead to reduce, cause the light efficiency of LED light engine to reduce.
Summary of the invention
For above-mentioned deficiency, the invention provides one can prevent lens surface from being scratched and the good LED light engine of sealing effectiveness, it not only can effectively prevent lens from being scratched or damaging in surface in installation, transport or use procedure, and the overall tightness of LED light engine can be ensured, LED light engine light efficiency can also be improved, its structure is simple, is suitable for large-scale promotion application.
The present invention is realized by such technical scheme: a kind of prevent lens surface from being scratched and sealing effectiveness better, the LED light engine of light efficiency can be improved, comprising:
