specific Embodiment approach

[0027] Such as figure 1 Shown is a cross-sectional view of Embodiment 1 of the present invention. The LED light-emitting module includes a light-emitting semiconductor 1 , a base 2 , a lens 3 , and a cavity 4 filled with a light conversion material. The surface of the base 2 has a reflective layer treated with high reflection, and the light-emitting semiconductor 1 is fixed on the base 2 to form a good heat conduction channel. The lens 3 covers the light-emitting semiconductor 1 and is separated from the light-emitting semiconductor 1. There is a cavity and an opening inside the lens 3, and the cavity is filled with a light conversion material 4, and the light conversion material is filled in the inner cavity of the lens through the opening; A transparent medium 5 is filled between the light emitting semiconductor 1 and the lens 3 .

[0028] The heat generated by the light-emitting semiconductor is conducted to the base, part of it is dissipated through the base, and the othe...

Abstract

The invention provides an LED luminous module, which can be an LED or an LED lamp. The LED luminous module comprises a luminous semi-conductor, a base, a lens, an optical converting material filling empty layer and a driving power, wherein the lens is internally provided with a cavity which is filled with optical converting materials; and fluid transparent medium is filled between the luminous semi-conductor and the lens. The LED luminous module can effectively improve luminous efficiency and reliability.

Description

technical field [0001] The invention relates to the field of LED (light-emitting diode) lighting, in particular to a high-efficiency, high-reliability LED and LED lamps. Background technique [0002] Due to the high luminous efficiency, long life, low working temperature, non-toxic and non-electromagnetic pollution of light-emitting diodes, LEDs have the characteristics of green environmental protection, high-power LED lamps have begun to be used in street lamps, tunnel lights, floodlights, spotlights, and special lights. , is likely to become the light source of the next generation of lighting tools. [0003] The light efficiency and reliability of LED lamps are affected by various factors such as heat dissipation conditions, light distribution schemes, and power drive efficiency. Compared with traditional light source lamps, the light efficiency of LED lamps currently on the market has no significant advantages. [0004] Patent Publication No. CN101075655A proposes a LED ...
