Embodiment 1

[0034] Embodiment one, see figure 1 , an LED light bulb, including a lamp base 1, six light-transmitting covers 2, a radiator 3 and a heat transfer body 4.

[0035] The lamp cap 1 is a screw lamp cap.

[0036] The heat transfer body 4 is a tubular structure with an inner hole 43 . The heat transfer body 4 is made of aluminum alloy. One end of the heat transfer body 4 is fixedly connected to the lamp cap 1 , and the other end of the heat transfer body 4 is fixedly connected to the radiator 3 .

[0037] The heat transfer body 4 is provided with six installation planes 41 . The installation plane 41 is an inclined plane inclined toward the lamp cap 1 . The inclination angle E of the installation plane is 25°.

[0038] One LED light source assembly 5 is installed on each installation plane 41 . A reflector 6 is installed on the LED light source assembly 5 , and the light-transmitting covers 2 are covered on the reflector 6 in one-to-one correspondence. The LED light source ...

Embodiment 2

[0045] Embodiment two, see Figure 4 , The difference from Embodiment 1 is that the lamp cap 1 is a bayonet lamp cap. The heat transfer body 4 is a plate structure. The mounting plane 41 is only provided on one side of the heat transfer body 4 . No reflector is provided. The light-transmitting cover 2 is a truncated cone with a large top and a small bottom. The lower end of the transparent cover 2 is connected to the lamp cap 1 , and the upper end of the transparent cover 2 is connected to the radiator 3 . The heat transfer body 4 and the LED light source assembly 5 installed on the installation plane 41 are located inside the transparent cover 2 . The inclination angle E of the installation plane is 40°.

[0046] see Figure 5 , a cooling groove 44 is opened on the side of the heat transfer body 4 . The purpose of designing the heat dissipation groove 44 is to increase the heat dissipation area of ​​the heat transfer body 4 .

[0047] see Image 6 The light bulb with...

Embodiment 3

[0048] Embodiment three, see Figure 7 , the difference from Embodiment 1 is that the LED lamp bead 52 is spherical. Two rows and three columns of LED lamp beads 52 are installed on each base 51 . The free ends of the heat dissipation protrusions 32 are located on the same spherical surface. No reflector is mounted on the mounting plane 41 .

[0049] see Figure 8 , the heat transfer body 4 is triangular truncated. Each side of the heat transfer body 4 constitutes a mounting plane 41 . The transparent cover 2 is in the shape of a truncated cone. The heat transfer body 4 is located in the same transparent cover 2 together with the three LED light source assemblies 5 respectively installed on the three installation planes.

Abstract

The invention relates to a lamp. An LED (Light Emitting Diode) bulb comprises a lamp cap, a light-transmitting cover and a heat transfer body, wherein one end of the heat transfer body is connected with the lamp cap, and the other end of the heat transfer body is connected with a radiator; the surface of the heat transfer body, which is positioned between the radiator and the lamp cap, is provided with a mounting plane; the mounting plane is provided with an LED light source component; and the light-transmitting cover covers the LED light source component. The invention, on one hand, aims to provide the LED bulb with a good radiating effect, so that the problem of poor radiating capacity of the conventional LED bulb is solved; and the invention, on the other hand, aims to provide the LED bulb with a lighting region in the rear lower region of the lamp cap, so that the problem of the non-ideal lighting effect when the conventional bulb is used in the vertically mounted lamp in which the lamp cap is in the lower space and the light is required to irradiate downward is solved.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED light bulb, which belongs to the lighting field. Background technique [0002] Due to the advantages of small size, low power consumption, long service life, high brightness, environmental protection and durability, LEDs are widely used in lamps. [0003] The structural form of the LED bulb is to install the heat transfer body on the lamp cap, install the LED light source assembly on the heat transfer body, and then install the luminous body composed of the heat transfer unit and the LED light source assembly in a transparent cover (lampshade). [0004] In the Chinese patent application publication number CN101893180A, a patent document titled "A LED Light Bulb" discloses an LED light bulb. The light bulb in this patent includes a lamp cap, a lamp holder, a lampshade, a radiator, and The driver is provided with an independent small light-emitting area on the bulb. The small light-emitting area i...
