Description

An all-round LED light bulb

technical field

The utility model relates to the field of lighting devices, in particular to an omnidirectional LED light bulb.

Background technique

Traditional lighting devices are mainly incandescent lamps and fluorescent lamps. Among them, incandescent lamps are widely used due to their low price and convenient application, but their luminous efficiency is low and their cost is high. The luminous efficiency of fluorescent lamps is greatly improved compared with incandescent lamps, but their life short.

LED lamps are the third generation of light sources after incandescent lamps and fluorescent lamps. They have the characteristics of high efficiency, environmental protection, long life, high color rendering index, and instant start. However, due to the limitation of the light-emitting characteristics of the LED itself and the structure of the LED props, its light-emitting angle is only 120°, which makes the surrounding area of the LED light form a blind area of brightness and affects the lighting effect.

The utility model adopts the following technical solutions:

An all-round LED light bulb, including a lamp cap, a lamp holder and a lampshade, the lamp cap and the lampshade are respectively fixed at both ends of the lampholder, and it is characterized in that: the lampholder includes a shell, a heat sink and an LED light source; the heat sink and the shell The body is socketed and fixed, and the top of the cooling seat is provided with a boss, and at least four slopes are formed on the outer periphery of the boss, and the LED light source is evenly distributed and fixed on the at least four slopes.

Preferably, the boss is integrally formed with the heat sink.

Preferably, the bottom end of the boss extends outward to form a positioning seat that fits and is fixedly sleeved on the top end of the heat sink.

Preferably, the cross-sectional area of the boss is small at the top and large at the bottom.

Preferably, the top end of the inclined plane is inclined in a direction close to the axis of the boss.

Preferably, the LED power supply includes several LED lamp beads and at least four substrates, the substrates are fixed on the inclined surface one by one, and an LED lamp bead is fixed on each substrate.

Preferably, the lamp holder further includes a reflective sheet, and the reflective sheet is sleeved on the outer periphery of the bottom end of the boss.

As can be seen from the above description of the utility model, compared with the prior art, the utility model has the following beneficial effects:

1. In the LED light bulb of the present utility model, the lamp holder is provided with a boss and a cooling seat, and the boss is provided with at least four slopes, and the top of the slope is inclined along the direction close to the axis of the boss, and each slope is provided with an LED power supply. So as to achieve 360° omni-directional irradiation;

2. In the LED light bulb of the present invention, the boss and heat dissipation can be integrated or split, with flexible structure and convenient assembly;

3. In the LED light bulb of the present invention, a reflective sheet can be set on the outer periphery of the boss according to the need, so as to enhance the light-gathering effect and increase the illumination brightness.

Detailed ways

The utility model will be further described below through specific embodiments.

Embodiment one

Referring to FIGS. 1 to 3 , an omnidirectional LED light bulb includes a lamp cap 10 , a lamp holder 20 and a lampshade 30 , and the lamp holder 10 and the lampshade 30 are respectively fixed at two ends of the lampholder 20 . The lamp holder 20 includes a housing 21 , a heat sink 22 , an LED light source and a reflective sheet 25 . The top of the heat sink 22 is provided with an integrally formed boss 26 . The periphery of the boss 26 is provided with four slopes 26b, the top of each slope 26b is inclined along the direction close to the axis of the boss 26, and the cross-sectional area of the boss 26 is small at the top and large at the bottom. The top end of the housing 21 is inserted into the heat sink 22 and locked to the bottom surface of the top end of the heat sink 22 by a screw 40 . A plurality of clamping strips 31 are provided at the bottom of the lampshade 30 , and a flange 22 a for clamping the clamping strips 31 is correspondingly provided on the inner periphery of the top of the heat sink 22 .
