Description

LED lights

technical field

The utility model relates to the field of illumination, in particular to an illuminating lamp with LED as a light source.

Background technique

Lighting lamps are the most frequently used electrical appliances in people's daily life. Although traditional lighting lamps using fluorescent tubes and other light sources can meet the lighting needs, their energy consumption is relatively high. And because the fluorescent tube contains heavy metal mercury, it is easy to cause pollution to the environment after being discarded.

LED (Light Emitting Diode) has been used more and more widely since its inception due to its characteristics of high light efficiency, no radiation and low power. With the advancement of technology, lighting lamps using LEDs as light sources have also been continuously innovated and developed. For example, in order to solve the problem that LEDs generate a lot of heat during work and affect the service life of LED lights, the Chinese invention patent with the patent application number 200810060246.2 and the name "A LED Light" proposes an aluminum alloy behind the LED illuminant Heat sink and cooling fan solution.

However, because the light beams emitted by LEDs are relatively concentrated, lighting lamps using LEDs as light sources often have problems such as small irradiation space and glare. In order to solve the above problems, people generally use a soft light shade directly at the LED light source. However, after using a soft light shade, it will inevitably reduce the light efficiency of the LED and reduce the brightness of the lighting.

Detailed ways

In the utility model, the light generated by the LED illuminant is illuminated after being diffusely reflected by a reflective surface with convex points/concave points on the surface, so that the illumination range of the illuminating lamp is increased, and local excessive intensity of the light is avoided.

As shown in FIGS. 1 and 2 , the LED lighting lamp in this embodiment includes a cooling frame, an LED illuminant 14 connected to the cooling frame, and a reflective surface 18 . The reflective surface 18 is located within the irradiation range of the LED illuminant 14 , and the reflective surface 18 is provided with a plurality of reflective convex points and/or concave points. When the light generated by the LED illuminant 14 irradiates the reflective surface 18, due to the existence of reflective convex points and/or concave points, the light produces diffuse reflection instead of specular reflection, so that the range of the entire LED lighting lamp is greatly increased. , and avoid glare.

The heat dissipation frame in the above embodiment includes a heat dissipation plate 11 , heat dissipation fins 12 located on the upper surface of the heat dissipation plate 11 and two heat conduction plates 13 located at both ends of the lower surface of the heat dissipation plate. The reflective surface 18 can be a reflective plate provided with reflective bumps and/or concave points on the front, and the back side of the reflective plate is directly attached to the lower surface of the cooling plate 11; in addition, the reflective surface 18 can also be realized in other ways, such as setting Reflective coating on the lower surface of the cooling plate 11. In this way, the heat generated by the reflective surface 18 due to light irradiation can also be released through the heat dissipation plate 11 and the heat dissipation fins 12 .

According to different requirements, the reflective surface 18 may be concave, convex or flat. For example, when a larger irradiation range is required, the reflective surface 18 adopts a convex surface; when stronger brightness is required, the reflective surface 18 adopts a concave surface.

The LED illuminant 14 includes a substrate (metal material that is easy to conduct heat, such as aluminum) and LEDs disposed on the front of the substrate, and the back of the substrate is attached to the inner side of the heat conducting plate 14 . The heat generated by the LED is conducted to the heat dissipation plate 11 and the heat dissipation fins through the substrate and the heat conduction plate 13 for release.

In order to improve the luminous efficiency, the angle between the inner side of the heat conduction plate 13 and the lower surface of the heat dissipation plate is less than 90 degrees. Therefore, the light generated by the LED energization can be more irradiated on the reflective surface 18 .

Similar to the existing lighting lamps, two lamp tube brackets 15 are sheathed at both ends of the cooling frame, and each lamp tube bracket 15 is provided with a lamp pin 16 and an electronic rectifier 19, wherein the output end of the electronic rectifier 19 is connected to LED illuminants. In this embodiment, the LED luminous body 14 and the heat conducting plate 13 at each end of the cooling frame are covered in a lamp tube bracket 15 , so as to avoid local over-intensity of the light generated by the LED luminous body 14 directly irradiated.

In order to facilitate heat dissipation at the end, a plurality of vent holes 17 can be provided on each lamp tube bracket 15 .

In order to enhance the lighting efficiency, a reflective layer (which may be a mirror surface) can be provided on the inner side of each lamp tube bracket, so that the light irradiated by the LED illuminant 14 onto the reflective layer can be reflected to the reflective surface 18 .

Similar to existing lighting lamps, in order to prevent dust from accumulating inside the lighting lamp (such as LED luminous bodies, etc.), a transparent lampshade can be provided.

Of course, in practical application, the LED lighting lamp is not limited to the structures in the above embodiments, for example, there may be only one LED illuminant, and the positions of the LED illuminant and the reflective surface may also be changed.
