Abstract

The invention relates to the field of illumination, in particular to an LED lamp. The LED lamp comprises a light source, a lampshade and a reflection layer, wherein the light source emits light through an external power source; the lampshade is of an annular structure, and the annular surface of the lampshade is in an inner arc shape; the reflection layer is closely attached to the inner wall of the annular surface of the lampshade; the light emitted by the light source on any point of the annular surface of the LED lamp is reflected by the reflection layer and then is mutually complemented with the light emitted by a point light source on the opposite side of the annular surface of the LED lamp. Due to the design of the LED lamp, original dazzling LED direct light is converted into reflection light and refracted light, the light becomes softer on the basis of not lowering the illumination efficiency, the comfort of people is greatly increased, and the LED lamp can be used in a living room, a bedroom and other environments.

Description

A kind of LED

Technical field

The present invention relates to lighting field, particularly relate to a kind of LED.

Background technology

LED is the abbreviation of light emitting diode, and it is the one of semiconductor diode, it is possible to electric energy is changed into luminous energy. Light emitting diode is the same with general-purpose diode to be made up of a PN junction, it may have unilateral conduction. When to light emitting diode plus after forward voltage, being injected into the hole in N district from P district and be injected into the electronics in P district by N district, near PN junction in a few micrometers respectively with the hole-recombination of the electronics in N district and P district, produce the fluorescence of spontaneous radiation. In different semi-conducting materials, electronics is different with the energy state residing for hole.

LED light source has the advantages such as energy-conservation, high brightness as a kind of novel light source, and its application in daily life is more and more extensive. But the light that LED light source sends very dazzling, if human eye is directly seen eyes can be produced harmful effect, so use LED as reading with still can, as bedroom background with then unsuitable for.

So, it is now desired to a kind of light fixture that can give out soft LED light is for being arranged on the ground such as bedroom, parlor.

Summary of the invention

It is an object of the invention to provide a kind of LED that can send soft light, it is intended to solve the problem that existing LED sends glare.

The present invention is achieved in that a kind of LED, and described LED includes light source, and described light source is by extraneous electrical source luminescent, lampshade, described lampshade has loop configuration, and the ring surface of described lampshade is inner circle arc, reflector layer, described reflector layer is close to the ring surface inwall of described lampshade, the light that on described LED ring surface, in any point, light source sends is complementary with the light that described LED ring surface opposite side point source sends through the reflection of reflector layer. LED provided by the invention is initially with the design of a kind of annular light, and when meeting illuminance, maximum magnitude reduces lamp body area to reduce the light stimulation to people. secondly, LED provided by the invention has the lampshade of the inner circle arc of a kind of annular, one layer of reflector layer is also had in lampshade, parallel by adjusting the light making the light that on described LED ring surface, in any point, light source sends send after the reflection of reflector layer light after described lampshade reflects with this light source, the light that on described LED ring surface, in any point, light source sends is complementary with the light that described LED ring surface opposite side point source sends through the reflection of reflector layer, this kind designs the direct light sent by LED light source and is converted into reflection or refraction light, make no matter user stands in any one direction, eye contact to light be not direct light, to reach the soft comfortable sensation of light.

The further technical scheme of the present invention is: described lampshade has the wide ratio of the sidewall of inner circle arc, the arc length of described inner circle arc and arc less than or equal to 1.5, be more than or equal to 0.2. So that the light sent is softer, it is necessary to the shape of lampshade is optimized.

Detailed description of the invention

Specific embodiment one

Fig. 1 illustrates the quick-fried according to figure of LED provided by the invention. It can be seen that described LED includes the installing rack 1 connected successively from the inside to surface, it is used for fixing whole LED lamp; Screw 2, is used for being fixed on power supply shell 5 by power supply shell line lid 3 and connecting terminal components 4; Power supply 6 is used for powering; Mylar film 7 fixes LED light source 9 together with lamp housing 8; Lampshade 12 is fixed on lamp housing 8 by connecting screw 10; Reflector layer 11 is close to the inner surface of lampshade 12.

Wherein the light transmittance of lampshade 12 is not less than 50%, is not more than 95%. Light rate is too low, and the light efficiency of lamp is just not high. Lampshade light transmittance is too high, it can be seen that LED bright spot. The light transmittance of the lampshade used in the specific embodiment of the invention one is 77%. The material of preparing of described lampshade is Merlon. Merlon is conventional transparent polymer material, technical maturity, it is simple to industrialized production.

The reflector layer 11 used in this specific embodiment is polyethylene terephthalate film, and this is a kind of common reflectorized material, and the reflecting rate of described reflector layer 11 is not less than 75%, and in this specific embodiment one, the light transmittance of reflector layer is 92%.
