Embodiment Construction

[0020] figure 1 It shows a side view of the light source of the LED lighting device according to the present invention. It can be seen from the figure that the light source of the LED lighting device according to the present invention adopts three LED light sources 2, and these LED light sources 2 are arranged side by side on the printed circuit board 1 superior. figure 2 It shows a top view of the light source of the LED lighting device according to the present invention. It can be seen from the figure that three LED light sources 2 are closely arranged together, and the distance between the edges of the LED chips of adjacent LED light sources 2 is 3.22 mm. In this embodiment, three low-power LED light sources with a luminous flux of 200 lumens are used, such as OSLON LED light sources produced by OSRAM Company. Of course, other numbers, such as four or five, of any type of low-power LED light sources may also be used.

Abstract

The invention relates to a Light-emitting diode (LED) lighting device. The LED lighting device comprises a printed circuit board (1), at least two LED light sources (2) which are arranged on the printed circuit board (1) side by side, and a reflector (3), wherein the reflector (3) comprises a center reflective face (3a) and at least one pair of edge reflective faces (3b) which are symmetrically arranged on two sides of the center reflective face (3a), the center reflective face (3a) is used for defining broadens of light shapes generated by light rays of the LED light sources (2), and the edge reflective faces (3b) are used for overlaying the reflected light rays to eliminate bright rays formed by light rays reflected by each edge reflective face (3b) in the light shapes. Besides, the invention further relates to a manufacture method of the LED lighting device.

Description

technical field [0001] The invention relates to an LED lighting device. In addition, the present invention also relates to a method for manufacturing the above-mentioned LED lighting device. Background technique [0002] Semiconductor light-emitting diode (LED) is a new type of electric light source. The light it emits is non-radiative light, with pure light color, concentrated beam, high color rendering index, good temperature characteristics, low power consumption, stable performance, long life, and no pollution. , Easy to use and so on. In addition, LEDs can be combined with multiple light sources, which will completely change the shape and arrangement of car headlights. Concept car shapes that could not be achieved with traditional light sources in the past can be perfectly realized with LED light sources. High beam and low beam can also be designed in the lampshade at the same time. As long as the power supply and LED heat dissipation design are appropriate, the life...
