Description

LED lighting device

technical field

The utility model relates to a lamp, in particular to a lamp device with a light-emitting diode as a light-emitting component.

Background technique

Light-emitting diodes are undoubtedly one of the most eye-catching products in recent years. Because light-emitting diodes have the advantages of low pollution, high brightness, etc., in addition, their luminous effect is not easy to scatter compared with traditional light-emitting components. Therefore, in addition to being widely used in current common lighting devices, LEDs are now also used in outdoor street lights.

Since the purpose of street lamps installed on the roadside is to guide pedestrians or vehicles, their lighting requirements are more stringent than those of ordinary households. At the same time, because it is set outdoors, it must be able to provide the same lighting brightness under different weather conditions. However, traditional street lighting devices use a single light-emitting component as a light source, and then use the reflection of the lampshade to expand the irradiation range. However, because the light source generated by the traditional light-emitting component is easy to scatter, it is difficult to gather the light through the reflection of the lampshade. Therefore make its illuminating effect limited, especially when the weather is unstable, the illuminating effect of this street lamp will appear blurred under the influence of mist or rainwater more and can't bring into play benefit.

Therefore, the advantages of light-emitting diodes just make up for the disadvantages of traditional light-emitting components. In addition to being difficult to scatter, the light source of light-emitting diodes can also provide good guidance for pedestrians or drivers in bad weather, so it has become the light source of current street lamps. One of the main components.

However, although the light-emitting effect of light-emitting diodes has the advantage that the light source is not easy to scatter, the original lighting of street lights requires not only strong brightness, but also a large lighting range. Therefore, the street lamp structures in the prior art all adopt a plurality of light-emitting diodes, which are arranged in two rows inside the lamp to enhance the luminous brightness of the light source; scope.

Although the above-mentioned structure uses a plurality of light-emitting diodes as the source of light, its luminous brightness is sufficient to provide a wide range of irradiation area, but due to the improper design of the lampshade structure in the prior art, the light source generated by the two rows of light-emitting diodes cannot completely pass through the lampshade Reflected out, so that the irradiated area of the lamp cannot expand with the increase of the intensity of the light source. Therefore, the efficiency of street lighting cannot be increased with the increase of light sources, but instead becomes a waste of resources. Therefore, it is necessary to find other ways to improve the defects of the known structures.

Utility model content

In view of the above-mentioned defects, the main purpose of this utility model is to provide an LED lighting device with converging light sources, which sets three rows of light-emitting diodes as the light source lamp group in the lamp holder, and improves the bending angle of the lampshade at the same time, so that the three rows The luminous path of the lamp group forms a converging effect, which not only improves the defect of light source scatter caused by the angle of the lampshade, but also completely reflects the luminous source to make full use of all luminous efficacy.

In order to achieve the above purpose, the LED lighting device provided by the present utility model includes: a lamp holder, the lamp holder has a lamp groove formed by inward depression, and the front and rear ends of the long sides of the lamp groove are bent inward and a plurality of lamp groups, each of which is provided with a plurality of light-emitting diodes, the plurality of lamp groups are arranged in three rows along the short side of the lamp groove, and the lamps in the left and right rows The groups are inclined inwardly according to the inner edge surface of the lamp groove, and the lamp groups arranged at the front and rear ends of the same row are also inclined inwardly.

According to the LED lighting device provided by the utility model, since three rows of light-emitting diodes are arranged in the lamp holder as the lamp group of the light source, the bending angle of the lampshade is improved at the same time, so that the light-emitting paths of the three rows of lamp groups form a convergence effect, which not only improves It eliminates the defect of light source scatter caused by the angle of the lampshade, and can completely reflect the light source to make full use of all luminous efficacy.
