Embodiment Construction

[0017] The following descriptions are only specific embodiments of the invention, and do not therefore limit the protection scope of the present invention.

[0018] see figure 1 , the LED lamp of the present invention includes a red LED light source group 20, a blue LED light source group 30, a light combining element 10, a first lens 40 and a second lens 50, wherein the red LED light source group 20 and the blue LED light source group 30 emit The light is combined by the light-combining element 10 and then emitted out of the lamp after passing through the first lens 40 and the second lens 50 . The first lens 40 is fixedly installed on the outgoing light path of the light combining element 10, and the first lens 40 is opposite to the outgoing surface of the light combining element, and can diverge the light emitted from the outgoing surface to the left and right directions; the second lens 50 is installed on the On the outgoing light path of the first lens 40 , most of the li...

Abstract

An LED lamp comprises two groups of LED light sources and a light synthesizing element. The two groups of LED light sources include the LED light source group of a first wavelength and the LED light source group of a second wavelength and does not include the LED light source of a third wavelength. The LED lamp has the advantages that the lamp only uses the light sources of two wavelengths to complete the function which can only be achieved by combining multiple single-color lamps of different colors, and energy saving is benefited.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED lamp. Background technique [0002] In the prior art, known color-tunable light sources are mainly based on LED modules that need to emit red, blue, green, and in some cases amber or more primary colors through different LEDs for each color . This means that there are at least as many LED chips as there are primary colors used. [0003] The patent of 200510121406.6 discloses a lamp capable of changing the color of the light. It combines red, blue, and green LED light sources into a beam of outgoing light through a light-combining element, so that various monochromatic lights and white lights can be emitted. Use one lamp to complete the functions that can only be realized by combining multiple existing single-color lamps of different colors, which is beneficial to energy saving. [0004] But need to use the light source of three different colors in the patent of 200510121406.6, cause volume big...
