Description
Technical field
This utility model relates to technical field of LED illumination, is specifically related to a kind of dishes shape LED.
Background technology
As green illumination, LED (light emitting diode) lamp is with its brightness height, energy-conserving and environment-protective, shock resistance and resists
The significant advantages such as shock stability is good, length in service life, light efficiency are high and be increasingly concerned.LED light source is not having
In the case of reflexed light ring reflection or lens refraction, its luminescent ligand light characteristic meets the spoke of lambert's luminous body
Penetrating rule, this kind of luminous body is also referred to as cosine luminous body.The light that LED light source sends not through luminous intensity distribution,
Its intensity of illumination is the most uneven, and the light that also cannot send LED light source is controlled.
In order to obtain more uniform lighting effect, general employing reflection lampshade will by one or many reflection
The emergent light of LED light source carries out luminous intensity distribution so that uniform illumination.But, through reflection-type LED of primary event outgoing
Light fixture, the light of LED light source outgoing the most all projects on reflector, some light without any instead
Penetrate direct outgoing to outside light fixture, this emergent ray angle and light distribution of being unfavorable for adjusting LED.And LED
The light that light source sends is the fitting structure of outgoing again after multiple reflections, and its structure is complex, produces into
This is higher, this most extra manufacturing cost increasing LED, is unfavorable for promoting the use of of LED.
Additionally, existing LED dishes shape aluminum 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) cost of light source is high) COB is as luminous source, by reflecting reflector more
Or the lens made of PMMA (polymethyl methacrylate) reach product set beam angle, make effectively
Light distribution in irradiated area.Shortcoming is owing to being existed by reflector by its light-emitting area of COB light source is little
Restriction in angle, its lighting area is little causes the irradiated area when equidistant position little, many by reflector
Appear in irradiated area after secondary refraction light skewness phenomenon, cause the defect such as black speck, macula lutea.Further,
PMMA easily causes to go bad under long-term high temperature and makes light transmittance decline, and the light decay making lamp is big.During illuminance is concentrated
Practising light highlight brightness higher, central light strength freely glides into effective dark space more than 10 °.Simultaneously at assembling product
Time, COB light source must be consistent with the central point of reflector, and if not on same central point, its beam angle goes out
It not the most to wait parabola phenomenon.
