Description
Technical field
The present invention relates to lighting area more particularly to a kind of LED light.
Background technique
LED is the abbreviation of light emitting diode, it is one kind of semiconductor diode, electric energy can be converted to luminous energy.Hair
Optical diode is made of as general-purpose diode a PN junction, it may have unilateral conduction.It is added when to light emitting diode
After forward voltage, the hole in the area N is injected into from the area P and is injected into the electronics in the area P by the area N, near the PN junction in a few micrometers respectively
With the electronics in the area N and the hole-recombination in the area P, the fluorescence of spontaneous radiation is generated.Electrons and holes institute in different semiconductor materials
The energy state at place is different.
LED light source has many advantages, such as energy conservation, high brightness as a kind of novel light source, and application in daily life is got over
Come more extensive.But the light that LED light source issues is very dazzling, if human eye, which is directly seen, to generate adverse effect to eyes,
So LED is used to use still as reading, and it is then unsuitable as bedroom background use.
So, it is now desired to a kind of lamps and lanterns that can give out soft LED light are used to be mounted on the ground such as bedroom, parlor.
Summary of the invention
The purpose of the present invention is to provide a kind of LED light that can issue soft light, it is intended to solve existing LED light and issue
The problem of glare.
The present invention is implemented as follows: a kind of LED light, the LED light includes light source, and the light source passes through extraneous power supply hair
Light；Lampshade, the lampshade have ring structure, and the annular surface of the lampshade is inner circle arc；Reflective layer, the reflective layer are close to
The annular surface inner wall of the lampshade；The light that light source issues on any point on the LED light annular surface is anti-by reflective layer
It penetrates complementary with the light that LED light annular surface opposite side point light source issues.LED light provided by the invention uses one kind first
The design of annular light, in the case where meeting illuminance, the diminution lamp body area of maximum magnitude is to reduce light to the thorn of people
Swash.Secondly, LED light provided by the invention has a kind of lampshade of the inner circle arc of annular, also one layer of reflective layer in lampshade leads to
Cross adjustment so that on the LED light annular surface on any point light source issue light after the reflection of reflective layer with the light source
Light of the light of sending after lampshade refraction is parallel, light source issues on any point on the LED light annular surface
Light by reflective layer reflection it is complementary with the light that LED light annular surface opposite side point light source issues, this kind design general
The direct light that LED light source issues is converted into reflection or refracted light, so that no matter user stands in any one direction, eyes
The light touched is not direct light, to reach the soft comfortable feeling of light.
A further technical solution of the present invention is: the lampshade has the side wall of inner circle arc, the arc of the inner circle arc
It is long to be less than or equal to 1.5 with the wide ratio of arc, it is more than or equal to 0.2.In order to enable the light issued is softer, need to lampshade
Shape optimizes.The arc width of the inner circle arc refers to the linear distance of Inner arc two-end-point, the arc length of the inner circle arc
Refer to the vertical range of arcuate midway point Yu Inner arc two end point connecting line.
A further technical solution of the present invention is: the lampshade has ring structure, the ratio of the annular outer diameter and internal diameter
Value is not more than 3.The more big then described LED light surface area of the ratio of outer diameter and internal diameter is bigger.
A further technical solution of the present invention is: the ratio of the thickness of the outer diameter of the lampshade and the lampshade is not less than 1,
No more than 10.The too thick illumination effect that will affect LED light of lampshade.
A further technical solution of the present invention is: the light transmittance of the lampshade is not less than 50%, it is not more than 95%.Light rate is too
Low, the light efficiency of lamp is not just high.Lampshade light transmittance is too high, it can be seen that LED bright spot.
A further technical solution of the present invention is: the material for preparing of the lampshade is polycarbonate.Polycarbonate is common
Transparent polymer material, technical maturity is convenient for industrialized production.
A further technical solution of the present invention is: the reflecting rate of the reflective layer is not less than 75%.Reflective layer reflecting rate is too
Low, the light efficiency of lamp is not just high.
A further technical solution of the present invention is: the material for preparing of the reflective layer is polyethylene terephthalate.
A further technical solution of the present invention is: the light emitting angle of the light source is 110 degree.
A further technical solution of the present invention is: the light source is LED point light source.
The beneficial effects of the present invention are: the design of this LED light is so that originally dazzling LED direct light transforms into reflected light
With refraction light, makes light become soft on the basis of not reducing illumination efficiency, considerably increase the comfort of people, can make
Used in environment such as parlor and bedroom.
