Description
Technical field
The present invention relates to lighting technical field, and may be used for the production of the lighting apparatus manufactured for common outdoor and room lighting.
Background technology
LED is a kind of high efficiency light source with low power consumption and long life.LED has the feature at low-angle yardstick place highlight strength.LED causes important vision loading (visualloading) and subconsciousness to expect to make house leave this luminaire as the application of the light source of high high light protection that need not be special.
A lot of country have employed special blind area and measures for controlling light source in the visual tolerable impact of people.The scattering of luminous flux that this problem is produced by emission source usually under the help of the distinct device of combined protection decoration and light diffusion function solves.Another solution is by former transmitting dispersion on large area surfaces, and its luminous intensity can not cause discomfort and will be enough to produce normal luminous level.
On the other hand, the electric energy of LED is converted to utilizing emitted light and is attended by heat generation.In this case, LED luminance stability depends on LED crystal temperature to a great extent.Heat up along with the reduction of crystal quantum efficiency.The problem producing hot dynamic equilibrium is more sharp-pointed, and the luminous flux of required generation normal illumination is more concentrated.This problem is especially typical in the light fixture that LED must be used to throw light on as routine.
There is a kind of LED, comprise the light diffusion shell be arranged on lamp body; The light guiding piece of hollow, has the surface formed by the taper light-reflecting components be arranged in light diffusion shell; LED is mounted close to light guide end (disclosed in 27 days January in 2010, KR20100009220 is claimed, MPKF21V5/00).
The deficiency of this LED is as follows: only a LED may be mounted close to light guide end, it can not provide the luminous flux being enough to use this lamp as conventional lighting device.
There is a kind of LED, comprise light diffusion shell; Body is equipped with cooling device; Be installed in the dome-shaped light reflection element of light reflecting cover inside.The LED of this lamp be installed into total luminous flux launched is launched by direct LED and from light reflection element nonreentrant surface reflection the cumulative of transmitting formed; Electrical switching device is arranged in body cavity; For connecting the parts of power supply circuits, such as, Screw type plug (patent US7600882, MPKF21V9/16 that on October 13rd, 2009 announces).
Also there is a kind of LED, it comprises the light diffusion shell being arranged on and being equipped with in the main body of surface cooling device; There is the light reflection element of recessed light reflective surface; LED is arranged on around light reflective surface, total luminous flux launched is launched by direct LED and is formed from the cumulative of transmitting that the nonreentrant surface of light reflection element reflects; Electrical switching device is arranged in body cavity; For connecting the parts of power supply circuits, such as, Screw type plug (patent CN201354962, MPKF21S2/00 that on December 2nd, 2009 announces).
Latter two analog has a common drawback: the LED light flux of part is directly launched by light diffusion shell, thus on the light emission surface of light diffusion shell, produces irregular brightness.
Technical result of the present invention is: improve light comfort level, improve light emission surface brightness uniformity and maintain LED operating temperature.
Summary of the invention
The present invention has following feature:
A kind of LED, comprising: light diffusion shell, it is made up of light transmissive material; Hollow ring radiator; Recessed reflector, it to be arranged in radiator chamber and to have the continuous surface reflected diffusely; Produce the luminous flux the LED be installed on heat sink inner surface of guiding lamp axes into, the reflector surface of instruction of can throwing light on; Luminous flux shaped member, it is arranged between reflector and light diffusion shell; Electrical switching device in radiator chamber; For being electrically connected to the parts in power supply circuits.
There is provided reflector diffusely reflecting surface successional demand by formation rule luminous flux and produce the diffusion of lamp non-uniform reflection light launch realize.
Based on identical reason, reflector and LED are installed in radiator chamber to adjust the brightness of the light emission surface of (level) light diffusing member.
Extra and the extension feature of described equipment is as follows:
-reflector surface can be covered by the mixture of similar luminescence medium particle or luminescence medium, and it provides the transmitting of the ripple with random length.Covering can be formed by long-time afterglow (afterglow) by luminescence medium, makes it that LED can be used as emergency light;
-luminous flux forming apparatus can be set to calibration lens or screen (screen), is arranged between LED and light diffusion shell, and it can be launched on reflector by antireflection part.The major function of all designs of luminous flux forming member is as follows: maximum using LED launches, and eliminates LED direct illumination light diffusion shell inner surface;
-screen surfaces can be plane or slight arch, and the roughness range shielding reflecting surface from mirror to diffusion, can depend on the required type of luminous flux;
-possible light source is as follows: the LED of emitting light flux has transmitting that is dark blue and/or ultraviolet spectra, or LED produces the white light luminous flux with the main cool tone that extra navy blue is launched;
-light diffusion shell may imply that scattering and/or the luminescence medium particle of reflection grain diffusely, thus reduces blind spot measurement.Light diffusion shell can be made up of the material with diffusive transport factor.If use cold White LED, then the color grade of the luminous flux caused controls to need the luminescence medium in reflector and light diffusion shell of less amount;
-light diffusion shell can have the surface by connecting arbitrarily to be formed, such as, Plane of rotation or surface, it combines in certain mode making it possible to control LED lamplight Flux Distribution;
-formed by cylinder surface with the part of the heat sink inner surface of the part fits for being connected to power supply circuits, there is n angle and guide, wherein: 3≤n≤∞.
