Embodiment 1

[0071] Combine Figure 3a An LED lighting device of this embodiment includes a lampshade 2 and at least two LED light sources 1 installed in the lampshade 2. The lampshade 2 is also provided with a reflective partition 3, and the side of the reflective partition 3 is a reflective surface; The LED light sources 1 are separated by the reflective partition 3.

[0072] Specifically, the lampshade 2 is mainly used to block light and avoid direct exposure of the light source to cause glare. The LED light source 1 can be arranged on the top plate of the lampshade 2.

[0073] Combine Figure 3a In this embodiment, the lampshade 2 has a rectangular structure, that is, the cross-sectional shape of the lampshade 2 obtained by cross-sectioning the lampshade 2 at the top parallel to the lampshade 2 is a rectangle, and the light distribution shape formed by it is a rectangle. Figure 6a As shown; the lampshade 2 forms 4 side walls, which can be inclined toward the outside from the end of the sid...

Embodiment 2

[0079] The structure of the lighting device of this embodiment is basically the same as that of embodiment 1. As a further improvement: the lampshade 2 in this embodiment is a wide-angle reflector lampshade, and the inner surface of a pair of side walls opposite to the reflective partition 3 in the lampshade 2 is reflective Surface, the top plate of the lampshade 2 and the reflecting surface form a certain included angle, the included angle is greater than 100°, such as 105°, 110°, 120°, etc. Specifically, the lampshade 2 includes a top plate at the top and a circumferential side wall, and the angle between the side wall and the top plate is the inclination angle of the side wall. The wide angle means that the inclination angle of the side wall opposite to the reflective partition 3 is not less than 100°. The combination of the wide-angle reflective lampshade and the reflective partition 3 increases the light projected by the LED light source 1 in the lampshade 2. The angle and...

Embodiment 3

[0083] As an improvement to the reflective partition 3, the reflective surface of the reflective partition 3 in this embodiment can be designed as one of a flat reflective surface, an arc-shaped reflective surface, and a multi-curved combined reflective surface according to different light distribution requirements. Its combination.

[0084] Combine Figure 3e Specifically, in this embodiment, the reflective partition 3 is in-line structure, and its reflective surface is a flat reflective surface, and the planar reflective surface is an inclined surface with a certain angle. The reflective partition 3 is in a direction away from the top plate. The thickness is gradually reduced to form a partition with a wide top and a narrow bottom, which is beneficial to enhance the light intensity of the outer edge.

[0085] In this embodiment, the included angle α is between 35° and 80°. When the angle is adjusted within this range, different illuminances can be obtained, for example, 45°, 50°,...

Description

Technical field [0001] The present invention relates to the technical field of LED lighting, and more specifically, to an LED lighting device and a lighting combination device thereof. Background technique [0002] Without any lighting distribution device, the light intensity distribution curve of the LED light source is Rambo figure 1 ), in order to achieve a large-angle uniform light distribution in the actual application of lighting fixtures, the currently commonly used solution is to equip the LED light source of road lighting fixtures or indoor lighting fixtures with optical lenses (such as Figure 2a , Figure 2b , Figure 2c ), the material is transparent plastic or transparent glass. In this way, large-angle uniform light distribution patterns such as oval, rectangular and asymmetrical shapes can be realized. The above light distribution methods are used to achieve the uniformity of illuminance in the national lighting technology standards And apply to various road lightin...
