Luminous diode lighting device

Abstract

The present invention discloses a luminous device for a light emitting diode. The device comprises a lamp box, a circuit board, the light emitting diode electrically connected with the circuit board, a reflection component and a lamp cover. The light emitting diode comprises a light-out lateral face and a top face connected with the light-out lateral face. The lamp box comprises an upper cover, alower cover opposite to the upper cover, a plurality of sidewalls connected with the upper cover and the lower cover, and an opening arranged on one of the sidewalls. The circuit board is positioned on the lower cover of the lamp box. Part of the light-out lateral face of the light emitting diode faces to the opening of the lamp box, and the top face of the light emitting diode faces to the uppercover. The reflection component, which is positioned inside the lamp box, is used for reflecting light rays of the light emitting diode, and the light rays are irradiated out from the opening. The luminous device for the light emitting diode has the advantage of comparatively small volume.

Description

LED lighting device technical field The invention relates to an illuminating device, in particular to an illuminating device using a light emitting diode. Background technique Light Emitting Diode (LED) has the characteristics of environmental protection, high mechanical reliability and high service life, so it is a new trend to use LED as the light source of the lighting device. Please refer to FIG. 1 , which shows a conventional elongated LED lighting device 10 (hereinafter referred to as LED lighting device). The LED lighting device 10 includes a light box 11 , a circuit board 12 , a plurality of edge-lit LEDs 13 , a reflection element 14 , a plurality of reflection sheets 15 and a diffusion sheet 16 . The light box 11 is a hollow elongated frame structure with an opening 112 . The circuit board 12 is also strip-shaped, and is correspondingly arranged on the bottom of the light box 11 . A plurality of edge-lit LEDs 13 are electrically connected and arranged on the u...

Problems solved by technology

However, although the collocation design of the LED 13 and the reflector 15 in the above-mentioned LED lighting device 10 can properly reduce the distance between the LED 13 and the diffusion sheet 16, there still needs to be a relatively large distance between the LED 13 and the diffusion sheet 16 to ensure that The light emitted by the diffusion sheet 16 is uniform, so the volume of the LED lighting device 10 is not easy to be further reduced, and it is difficult to adapt to the development trend of light and thin products
