Description

led light

technical field

The present invention relates to the technical field of lighting, and more particularly to an LED (Light Emitting Diode, light emitting diode) lamp.

Background technique

In recent years, based on the characteristics of energy saving, environmental protection, high efficiency, small size, and long life, LED (Light Emitting Diode, light-emitting diode) lamps are more and more popular among people. The LED lamps have replaced traditional incandescent lamps and fluorescent lamps. a mainstream trend.

Existing LED lamp tubes generally include a lampshade, an LED light source assembly, an LED driver assembly, and a housing. The assembly and the LED driving assembly are installed on the lampshade. The shell is generally made of aluminum material to dissipate heat and prolong the service life of the LED lamp. However, the heat dissipation effect of the shell is relatively poor. In addition, if a heat dissipation device is added to the casing, the load of the heat dissipation casing will be increased, and the cost will be higher.

Therefore, it is necessary to provide an improved LED lamp to overcome the above defects.

Contents of the invention

The purpose of the present invention is to provide an LED lamp, the heat dissipation effect of the shell of the LED lamp is better, thereby prolonging the service life of the LED lamp, and the cost is low.

In order to achieve the above object, the present invention provides an LED lamp, which includes a lampshade and a lamp body connected to the lampshade. surface cooling fins.

Compared with the prior art, since the outer surface of the LED street lamp housing of the present invention protrudes outward to form a number of heat dissipation fins perpendicular to the outer surface, the heat dissipation area is increased, the heat dissipation effect is effectively enhanced, and the cost is low.

Preferably, the heat dissipation fins are arranged in parallel, and grooves are formed between adjacent heat dissipation fins.

Specifically, the housing has a base plate and an arc-shaped plate, the base plate and the arc-shaped plate are integrated, and the outer surface of the arc-shaped plate protrudes outward to form the heat dissipation fins.

Specifically, the lamp body also includes an LED light source assembly and an LED driver assembly, the housing also has a housing cavity, the LED light source assembly is installed on the substrate, and the LED driver assembly is accommodated in the housing cavity , the LED driving component is connected to and drives the LED light source component to work.

Preferably, both the lampshade and the housing have semicircular cross-sections.

The present invention will become clearer through the following description in conjunction with the accompanying drawings, which are used to explain the embodiments of the present invention.

Detailed ways

Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements. As mentioned above, the present invention provides an LED lamp, since the outer surface of the housing protrudes outward to form a number of heat dissipation fins perpendicular to the outer surface, thereby increasing the heat dissipation area and effectively enhancing the heat dissipation effect. And the cost is low.

As shown in Figures 1 and 2, the LED lamp of the present invention includes a lampshade 10, a lamp body 20, and two end covers 30, the lampshade 10 is connected to the lamp body 20, and the two end covers 30 are fastened to the lamp body respectively. Two ends after the lampshade 10 and the lamp body 20 are connected.

Specifically, as shown in FIGS. 2 to 4 , the lamp body 20 includes a housing 201 , an LED light source assembly 202 and an LED driving assembly 203 , and the LED light source assembly 202 and the LED driving assembly 203 are installed on the housing 201 . Specifically, the housing 201 includes a base plate 2011, an arc-shaped plate 2012 and a housing cavity 2013, the base plate 2011 and the arc-shaped plate 2012 are integrated, and the base plate 2011 and the arc-shaped plate 2012 forms the accommodating cavity 2013. The LED light source assembly 202 is mounted on the substrate 2011, the LED driving assembly is accommodated in the housing cavity 2013, and the LED driving assembly 203 is connected to drive the LED light source assembly 202 to work.

As shown in Figure 3, the outer surface of the arc-shaped plate 2012 protrudes outward to form a number of heat dissipation fins 2014 perpendicular to the outer surface, the heat dissipation fins 2014 are arranged in parallel, and the adjacent heat dissipation fins Between 2014 a trench is formed. In this way, the principle of air convection is used to take away the heat emitted from the surface of the housing 201 at any time and quickly, and the temperature inside the LED lamp is always controlled within 55 degrees, effectively ensuring the normal operation of the LED light source assembly 202 temperature and environment, thereby ensuring the service life of the LED lamp.

Preferably, as shown in FIG. 3 , the cross-sections of the lampshade 10 and the housing 201 are both semicircular.

It should be noted that the lampshade 10 of the LED lamp of the present invention is made of a unique polycarbonate raw material containing secondary optical enhancement particles, and the light transmittance can reach more than 90%.

The present invention has been described above in conjunction with the best embodiments, but the present invention is not limited to the above-disclosed embodiments, but should cover various modifications and equivalent combinations made according to the essence of the present invention.
