Abstract

The invention relates to an LED lamp with a large visual angle and smooth pictures. The inner contour of a lamp cup of a traditional LED lamp is of a right-angle square shape, the visual angle is small, and pixel granular sensation of an LED screen is obvious, so that picture transition is not smooth enough. The LED lamp with the large visual angle and the smooth pictures comprises a lamp base, an LED light-emitting chip and a lamp cup, wherein the LED light-emitting chip is arranged in the center of the lamp base, and the lamp cup is arranged on the lamp base and covers the LED light-emitting chip. The lamp cup is annular, the periphery contour of the lamp cup is square, the inner contour of the lamp cup is of a stair landing shape, and arc transition zones are arranged on the corners of the inner wall of the lamp cup. According to the design, the traditional right-angle inner contour of the lamp cup is improved to be an oblique-angle inner contour, and the arc transition zones are arranged additionally, so that the visual angle of the LED lamp is increased. The LED lamp with the large visual angle and the smooth pictures is simple in structure, low in cost and capable of increasing the visual angle of the lamp and reducing the pixel granular sensation of the LED screen, so that picture transition is smoother.

Description

A kind of large visible angle smoothed image LED lamp

Technical field

The present invention relates to a kind of LED lamp, particularly a kind of large visible angle smoothed image LED lamp.

Background technology

LED is English Light Emitting Diode---the abbreviation of light-emitting diode; its basic structure is an electroluminescent semi-conducting material, places on the leaded shelf, then uses epoxy sealing all around; play the effect of protection internal core, so the anti-seismic performance of LED is good.

Profile is all at right angles square in the Lamp cup of tradition LED lamp, and visible angle is less, and the pixel granular sensation of LED screen is obvious, and the image that makes is excessively not smoothly smooth and easy.

Summary of the invention

The technical problem to be solved in the present invention is the defects that how to overcome prior art, and a kind of large visible angle smoothed image LED lamp is provided.

For solving the problems of the technologies described above, this large visible angle smoothed image LED lamp comprises lamp socket (1), LED luminescence chip (2) and Lamp cup (3), wherein LED luminescence chip (2) is arranged on lamp socket (1) central authorities, Lamp cup (3) is arranged on the lamp socket (1), and shrouds in LED luminescence chip (2) outside; Described Lamp cup (3) ringwise, its peripheral profile be the square, in-profile is trapezoidal shape, and is provided with arc transition band (4) in inwall corner.So design is modified into profile in the oblique angle with Lamp cup by profile in traditional square, and sets up the arc transition band, has increased the visible angle of LED lamp.

As optimization, described LED luminescence chip (2) has three groups, is respectively red light chips (201), green glow chip (202) and blue chip (203).Do not limit the arrangement mode of red light chips (201), green glow chip (202) and blue chip (203).

As optimization, described lamp socket (1) is square, and its peripheral profile is consistent with the peripheral profile of Lamp cup (3).

As optimization, described LED luminescence chip (2) upper end is 0.5～1mm apart from Lamp cup.So design has reduced the distance of chip to the Lamp cup upper surface, has enlarged visible angle.

As optimization, the lighting angle of new SMD SMD lamp---1/2 times of light intensity can reach more than 140 degree.So design, the lighting angle of relatively old SMD SMD lamp---1/2 times of light intensity generally is about 120 degree, has increased the visible angle of LED lamp.

A kind of large visible angle smoothed image LED modulated structure of the present invention is simple, with low cost, not only increases the visible angle of lamp, and reduces the pixel granular sensation of LED screen, makes image excessively more level and smooth.

Embodiment

As shown in Figure 1, this large visible angle smoothed image LED lamp comprises lamp socket 1,LED luminescence chip 2 andLamp cup 3, and whereinLED luminescence chip 2 is arranged on lamp socket 1 central authorities, andLamp cup 3 is arranged on the lamp socket 1, and shrouds inLED luminescence chip 2 outsides; DescribedLamp cup 3 ringwise, its peripheral profile be the square, in-profile is trapezoidal shape, and is provided with arc transition band 4 in inwall corner.DescribedLED luminescence chip 2 has three groups, is respectivelyred light chips 201,green glow chip 202 and blue chip 203.Do not limit the arrangement mode ofred light chips 201,green glow chip 202 and blue chip 203.Described lamp socket 1 is square, and its peripheral profile is consistent withLamp cup 3 peripheral profiles.DescribedLED luminescence chip 2 upper ends are 0.5～1mm apart from Lamp cup.

The lighting angle of new SMD SMD lamp---1/2 times of light intensity can reach more than 140 degree.The lighting angle of relatively old SMD SMD lamp---1/2 times of light intensity generally is about 120 degree, has increased the visible angle of LED lamp.

The present invention includes but be not limited to above-mentioned execution mode, anyly meet the product that these claims are described, all fall within protection scope of the present invention.
