Thin high power LED (Light Emitting Diode) line lamp

Abstract

The invention discloses a thin high power LED (Light Emitting Diode) line lamp. The thin high power LED line lamp also comprises a long strip light guiding plate (6) apart from the parts of the traditional line lamp; LED light sources (3) are formed by lengthwise arranging a plurality of LED lamp beads in one to three rows; the heat sink comprises a heat dissipation baseplate (4) and cooling fins (7); the heat dissipation baseplate (4) takes the shape of a long strip; the cooling fins (7) are arranged at intervals in parallel along the direction vertical to the heat dissipation baseplate; a light emitting module (8) is formed by the LED light sources (3) and the heat sink; the light emitting module (8) and the long strip light guiding plate (6) are horizontally arranged; the horizontally arranged light emitting module (8) is glued to the side arris of the light guiding plate (6); and the LED light sources (3) face toward the interior of a light guiding plate body. The thin high power LED line lamp has the advantages that the characteristics of the LED light sources and indoor illumination are fully considered; as the light sources are horizontally arranged, the light emitting effect is effectively improved, and the heat dissipation effect is good; and the body of the thin high power LED line lamp is light and thin.

Description

[0001] technical field [0002] The invention relates to the field of semiconductor lighting lamps, in particular to a thin high-power LED line lamp with cooling fins distributed on the side of the lamp body. [0003] Background technique [0004] Semiconductor lighting has many advantages such as high brightness, low energy consumption, long life, and environmental protection, and is being more and more widely used in various fields of lighting. , especially in the more demanding indoor lighting, the design of its lamps has more and stricter requirements.

Linear light is a high-end decoration and lighting product, which is very popular among consumers. However, the use of LED light sources in ordinary linear lights has serious light spots and glare due to the use of ordinary diamond-shaped lampshades. Therefore, the existing LED linear lights The lamp forms a soft and uniform light emitting surface by adding a light distribution lampshade on the lamp housing. Chinese patent document CN201764281U discloses an LED line lamp. The LED light source is installed in the lamp housing, and the straight stripe lamp shade is fixed on the lamp housing. The LED light source is placed in the straight-stripe lampshade, which is characterized in that a transparent straight-stripe board is installed between the LED light source and the straight-stripe lampshade, and the straight stripes on the straight-stripe lampshade and the straight stripes of the transparent straight-stripe board form an orthogonal shape. The light emitted by the LED light source of the scheme is reflected and refracted on the transparent straight striped plate and the straight striped lampshade respectively, and the light is further uniformed. The requirements of linear lights, on the one hand, when the luminous intensity of a single lamp bead increases, the spot and glare effects will become more obvious; on the other hand, because the radiator is located on the back of the lamp, it is not only difficult to meet the heat dissipation requirements of high-power LED lamps , and it is difficult to reduce the thickness of the lamp
