Description

LED Bulb

technical field

The utility model belongs to the field of bulb lamps, in particular to an LED bulb lamp. the

Background technique

At present, there are many structures of LED bulb lamps on the market, most of which include radiators, spherical lampshades, LED light sources and driving power supplies. One end of the radiator is connected to the lamp holder, and the other end is connected to the LED light source and the lampshade. The material of the heat sink is generally die-cast aluminum, and the heat dissipation is average. Although the appearance design is as beautiful as possible, the heat sink is outside, which is not very beautiful. the

The heat dissipation of LED bulbs is extremely important. Excessive temperature will shorten the life of LEDs. Therefore, LED bulbs with good heat dissipation, beautiful appearance and simple structure are urgently needed by the market. the

Utility model content

The technical problem to be solved by the utility model is to provide an LED bulb lamp with simple and novel structure, beautiful appearance and good heat dissipation effect. the

In order to solve the above problems, the technical solution adopted by the utility model is: an LED bulb lamp, including a lampshade, a radiator, a lamp holder, an LED light source, a light source substrate, a driving power supply, a casing and a plastic clip, wherein the LED light source is welded On the light source substrate, the shell is fixed on the radiator by screws. The radiator is a stretched aluminum profile. There are holes on both ends to fix the light source substrate and the shell respectively. There are steps on the outside of the upper end surface. On the steps of the radiator, the teeth around the plastic clip are embedded with the protrusions on the inner side of the upper end of the housing, the light source substrate is pressed against the plastic clip and fixed on the upper surface of the radiator by screws, and the lampshade is embedded in the groove of the plastic clip. And there is a gap with the shell. the

The lampshade is a hemispherical structure made of glass, and the surface of the inner wall is coated with electrostatic whitening. the

A protrusion is provided on the inner side of the upper end of the shell, and ventilation holes are evenly provided on the inclined surface of the lower end. the

The drive power is placed inside the casing. the

The lamp head is fixed on the shell. the

Teeth are evenly distributed around the plastic clip, and a clip slot is formed on the upper end surface. the

The beneficial effects produced by adopting the above-mentioned technical solution are: the utility model has a simple and novel structure, beautiful appearance, and good heat dissipation effect. The clip and radiator form a "chimney effect", which is good for heat dissipation and improves the service life of the lamp. the

Detailed ways

The utility model is further described in detail below in conjunction with the accompanying drawings: as shown in Figure 1, Figure 2, Figure 3, Figure 4 and Figure 5, a LED bulb lamp consists of a glass lampshade 1, an LED light source 2, a light source substrate 3, Composed of plastic clip 4, radiator 5, shell 6, drive power 7 and lamp holder 8;

The LED light source 2 is welded on the light source substrate 3 . The shell 6 is fixed on the radiator 5 by screws. The plastic clip 4 is clipped on the step of the radiator 5, and the teeth around the plastic clip 4 are embedded with the protrusions on the inner side of the upper end of the shell 6 so that it does not rotate and acts as a fixation. The light source substrate 3 is tightly pressed against the plastic clip 4 and fixed on the end surface of the heat sink 5 by screws, and thermal conductive grease is coated between the light source substrate 3 and the heat sink 5, so the heat dissipation effect is good. The glass lampshade 1 is embedded in the groove of the plastic clamp 4, and there is a gap between it and the shell. Because the inner surface of the lampshade is electrostatically painted white, it is conducive to light diffusion and eliminates glare; the lampshade is made of glass, which can dissipate part of the heat of the light source. The driving power supply 7 is placed inside the casing 6 . The lamp cap 8 is fixed on the shell 6 . The heat sink 5 is a stretched aluminum profile, in the shape of a sunflower, with a large heat dissipation area and good heat dissipation effect. There are through holes on the end surface, which can respectively fix the light source substrate 3 and the housing 6 . Ventilation holes 9 are uniformly arranged on the slope of the lower end of the housing 6, which can form a "chimney effect" with the plastic clamp 4 and the radiator 5, so that the heat flow inside can be diffused to the outside through the ventilation holes. the

To sum up, the utility model has the advantages of simple and novel structure, beautiful appearance, good heat dissipation effect, long service life and convenient installation. The glass lampshade can not only dissipate part of the heat, but also the inner surface is electrostatically painted white, which is conducive to the uniform diffusion of light and can avoid glare. the
