Embodiment Construction

[0034] The present invention will be further described below with specific examples.

[0035] Such as figure 1 As shown, the lighting device of the present invention includes a heat sink 10 , a plurality of light emitting modules 20 and brackets 30 attached to the heat sink 10 .

[0036] see figure 2 and image 3 , the heat sink 10 is integrally extruded from a metal with good thermal conductivity. The heat sink 10 includes a heat conducting plate 110 and a plurality of cooling fins 120 integrally extending from the heat conducting plate 110 . The heat conducting plate 110 is in the shape of a flat plate. The heat conducting plate 110 has a first side 111 and a second side 112 opposite to each other. The heat dissipation fins 120 extend from the first side 111 of the heat conducting plate 110 perpendicular to the first side 111 . The second side surface 112 of the heat conducting plate 110 is provided with a plurality of grooves 130 arranged in parallel, and the interva...

Abstract

The invention relates to an illuminating apparatus, which comprises a radiator, light-emitting modules and a support, wherein the light-emitting modules are pasted to one side of the radiator; and the support is connected with the radiator. The radiator comprises a heat conduction plate and a plurality of fins extending from the first side face of the heat conduction plate. The light-emitting modules are pasted to the second side face of the heat conduction plate, which is opposite to the first side face of the heat conduction plate. Each light-emitting module comprises a radiating seat body; each radiating seat body is provided with a bearing face; and each bearing face is provided with a light-emitting element. The distances between the bearing faces and the second side face of the heat conduction plate are gradually changed from one end of the heat conduction plate to the other opposite end the heat conduction plate, and thereby, a user can flexibly regulate the optical field distribution condition of the illuminating apparatus as needed.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an illuminating device capable of adjusting light field distribution. Background technique [0002] A light emitting diode (Light Emitting Diode, LED) is a semiconductor element that can convert electric current into light in a specific wavelength range. Light-emitting diodes can be widely used as light sources in the field of lighting because of their advantages such as high brightness, low operating voltage, low power consumption, easy matching with integrated circuits, simple driving, and long life. [0003] In a lighting device composed of light-emitting diodes, the distribution of its light field is a very important performance index. In different applications, it is usually necessary to use lighting devices with different light field distributions. However, after the lighting device is assembled, its light field distribution is usually fixed, and it is difficult for users to chan...
