Description
Technical field
The present invention relates to technical field of LED illumination, a kind of dishes shape LED is specifically related to.
Background technology
As green illumination, LED (light emitting diode) lamps are with its brightness height, energy-conserving and environment-protective, shock resistance and resist
The significant advantages such as shock stability is good, service life length, light efficiency height and be increasingly concerned.LED/light source is not having
In the case of by reflexed light ring reflection or lens refraction, its luminous light distribution characteristic meets the spoke of lambert's illuminator
Rule is penetrated, this kind of illuminator is also referred to as cosine illuminator.The light that LED/light source is sent it is no through matching somebody with somebody light when,
Its intensity of illumination is very uneven, and also the light that LED/light source is sent can not be controlled.
It is general to use reflection lampshade by one or many reflections in order to obtain more uniform lighting effect
The emergent light of LED/light source carries out luminous intensity distribution so that uniform illumination.But, the reflection-type LED through primary event outgoing
Light fixture, the light of LED/light source outgoing is not projected on reflector all, and some light is without any anti-
Penetrate outside direct outgoing to light fixture, this is unfavorable for the emergent ray angle and the light distribution that adjust LED.And LED
The light that light source is sent fitting structure of outgoing again after multiple reflections, its structure is complex, is produced into
This is higher, and this just additionally increases the manufacturing cost of LED, is unfavorable for promoting the use of for LED.
In addition, existing LED dishess shape aluminium reflection (Parabolic Aluminum Reflector, PAR) lamp
The formation of beam angle is by (COB (Chip On Board, chip on board) light source is than SMD (Surface Mounted
Devices, surface mount device) light source cost it is high) COB is as light emitting source, by reflecting reflector more
Or the lens that are made of PMMA (polymethyl methacrylate) reach product set beam angle, make effective
Light distribution in irradiated area.Have the disadvantage due to existing by the way that COB light source its light-emitting area is small by reflector
Limitation in angle, its lighting area is small to cause the irradiated area at equidistant position small, many by reflector
Appeared after secondary refraction in irradiated area light distribution non-uniform phenomenon, cause the defects such as blackspot, macula lutea.Also,
PMMA easily causes to go bad at a high temperature of long-term declines light transmittance, makes the light decay of lamp big.During illuminance is concentrated
Habit light intensity brightness is higher, and central light strength freely glides into effective dark space more than 10 °.Simultaneously in assembling product
When, the central point of COB light source and reflector must be consistent, if on same central point, its beam angle does not go out
It is not now to wait parabola phenomenon.
