[0098] Below, the present invention will be described based on the accompanying drawings. figure 1 and figure 2 An LED lamp 10 of an embodiment of the present invention is shown in FIG. The LED lamp 10 has: a resin cover body 11; a radiator 12, which is made of metal materials such as aluminum with excellent thermal conductivity and heat dissipation; a module circuit board 14, which is equipped with an LED chip 13; a lighting circuit 15, which Power supply to LED 13 pieces; barrel member 16; lamp cap 17, which has a shape and size conforming to international standards.

[0099] The radiator 12 has a substantially flat dish shape, and the module circuit board 14 is fixed to the central portion of the inner end surface. A cup-shaped resin cover 11 is attached to the outer peripheral portion of the radiator 12 . A mirror surface 18 having a parabolic shape is formed on the inner peripheral surface of the resin cover 11 .

[0109] image 3 and Figure 4 An LED lamp 20 of a second embodiment of the present invention is shown. This LED lamp 20 has a barrel member 21 made of plastic, and one end of the barrel member 21 is mounted on the outer peripheral portion of the radiator 12, and a lamp cap 17 is mounted on the other end. In addition, a lighting circuit 15 is provided inside the cylindrical member 21 .

[0110] The tube member 21 is composed of a large-diameter tube part 21a, a small-diameter tube part 21b, and a tapered annular surface 21c connecting the large-diameter tube part 21a and the small-diameter tube part 21b. The base 17 is connected to the small-diameter cylindrical portion 21b.

[0111] as in Figure 5 As shown in the enlarged illustration, the large-diameter cylindrical portion 21a and the small-diameter cylindrical portion 21b have substantially the same thickness T1, and the thickness T2 of the tapered annular surface 21c is formed to be thinner than the thickness T1. In a...

[0120] Figure 8 An LED lamp of a third embodiment is shown. This LED lamp 30 has a barrel portion 31 made of plastic. The barrel portion 31 is composed of a large-diameter barrel portion 31a, a small-diameter barrel portion 31b, and a tapered annular surface 31c connecting the large-diameter barrel portion 31a and the small-diameter barrel portion 31b. 31c has substantially the same thickness, and a plurality of circular through-holes 31d are formed in the tapered annular surface 31c. In particular, through-holes 31e are formed at equal intervals along the entire circumference of the large-diameter cylindrical portion 31a at the connecting portion between the large-diameter cylindrical portion 31a and the tapered annular surface 31c. In addition, through-holes 31f are formed at equal intervals along the entire circumference of the small-diameter cylindrical portion 31b at a portion close to the connecting portion between the small-diameter cylindrical portion 31b and the ta...

Abstract

An LED lamp includes a heat dissipater having two ends, a module substrate fixed to one end of the heat dissipater and mounted with an LED chip, a cap mounted on the other end side of the heat dissipater, a lighting circuit provided between the module substrate and the cap to supply electric power to the LED chip, the lighting circuit being electrically connected to the cap, and a cylindrical member which is interposed between the heat dissipater and the cap and is flexible so that the heat dissipater is tiltable relative to the cap.

Description

technical field [0001] The invention relates to an LED lamp with a built-in LED chip as a light source. Background technique [0002] Recently, instead of an incandescent lamp with a large power consumption, there is an increasing demand for an LED lamp using an LED as a light source with a low power consumption. [0003] Usually, this kind of LED lamp has: a metal radiator such as aluminum, which has excellent thermal conductivity; a lamp cap, which is installed at one end of the radiator, and a lampshade, which is made of light-transmitting glass or plastic material, has a hemispherical top, and Installed on the other end of the heat sink, the module circuit board is equipped with LED chips, and the lighting circuit supplies power to the LED chips; and, this kind of LED lamp also has the following structure: the module circuit board and the lighting circuit are installed on the heat dissipation On the body, the LED chip is covered by the lampshade, and the lighting circui...
