Example Embodiment

Specific embodiment one

[0022] figure 1 It shows a burst shot of the LED lamp provided by the present invention. It can be seen from the figure that the LED lamp includes a mounting frame 1 connected in sequence from the inside to the outside, which is used to fix the entire LED lamp body; a screw 2 is used to fix the power supply shell cover 3 and the terminal assembly 4 to the On the power shell 5; the power source 6 is used to supply power; the mylar sheet 7 and the lamp shell 8 fix the LED light source 9 together; the connecting screw 10 fixes the lamp shade 12 on the lamp shell 8; the reflective layer 11 is close to the inner surface of the lamp shade 12.

[0023] The light transmittance of the lampshade 12 is not less than 50% and not more than 95%. If the light rate is too low, the light efficiency of the lamp is not high. The light transmittance of the lampshade is too high, and the LED bright spots can be seen. The light transmittance of the lampshade used in the firs...

Example Embodiment

Specific embodiment two

[0030] The inner diameter of the lampshade in the second embodiment is 200 mm, the outer diameter is 600 mm, and the ratio of the outer diameter to the inner diameter is 3; the thickness and arc width are 600 mm, and the inner arc length is 120 mm. The ratio is 1, and the ratio of the arc length to the arc width of the inner arc is 0.2, and the others are the same as in the first embodiment.

Example Embodiment

Specific embodiment three

[0031] In this specific embodiment, except that the inner diameter of the lampshade is 200 mm, the outer diameter is 220 mm, the ratio of the outer diameter to the inner diameter is 1.1; the arc width and thickness are 22 mm, the inner arc length is 33 mm, and the ratio of the outer diameter to the thickness is 10. The ratio of the arc length to the arc width of the inner arc is 1.5, and the others are the same as in the first embodiment.

[0032] The design of using this LED lamp makes the originally dazzling LED direct light converted into reflected light and refracted light, and the light becomes soft without reducing the lighting efficiency, which greatly increases the comfort of people. It can be used in living room, bedroom and other environments. .

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

technical field [0001] The invention relates to the field of lighting, in particular to an LED lamp. Background technique [0002] LED is the abbreviation of light-emitting diode, which is a kind of semiconductor diode, which can convert electrical energy into light energy. Like ordinary diodes, light-emitting diodes are composed of a PN junction and also have unidirectional conductivity. When a forward voltage is applied to the light-emitting diode, the holes injected from the P region to the N region and the electrons injected from the N region to the P region are respectively connected to the electrons in the N region and the vacancies in the P region within a few microns near the PN junction. Hole recombination, resulting in spontaneous emission of fluorescence. The energy states of electrons and holes are different in different semiconductor materials. [0003] As a new type of light source, LED light source has the advantages of energy saving and high brightness, an...
