With the development of the industry, customer needs are more and more clearly directed to convenience and conciseness, and CCT changeable COB gradually enter the public vision. However, the problem that follows is that using a conventional lens to match with CCT changeable COB, and the light mixing effect is not good.
Chameleon series came into being. Based on the KA lens, optimized adjustments are made to the CCT changeable COB, which is suitable for the needs of more and more color mixing lenses, so that the light spots are mixed uniformly.
Conventional lens (medium and large angle) with CSP mixedtype CCT changeable COB, the light mixing effect is barely acceptable. But thelens below 30 degrees, with the mixed color temperature light source, the colormixing ability seems to be inadequate. Chameleon series, focusing on the middle cylindrical light source at the beginning of design, use of DTW series light source. This series of lenses can not only match a single channel Dim to warm light source, but also perfectly match the dual channel Tunablelight source.
Market Pain Point
The same space brings different experiences and feelingsunder the effect of different color temperatures. CCT lamps can create different atmospheres according to different scene needs, and are deeply lovedby the market.
However, the secondary light distribution of the CCT light source has always been a difficult problem.The existing light distribution solutions on the market are difficult to achieve a good color mixing effect and uniform light spots.

Principle of Design
The reflecting surface of the lens uses the principle of differential and integration. The light emitted by the light source is differentiated by a large number of scales, and the light source is divided into several sub-light sources (differential). Each sub-light source ispresented separately on the illumination light field, and by rearranging and overlapping the centers, rotating and superimposing (integration), the light of different color temperatures is cross-distributed to achieve amixed light effect. Differential redistribution of the light source not only makes the light more finely distributed and achieves a good light mixing effect, but also the brightness of the light emitting surface is uniform andeven. The area reduces the glare of the lens.
The transmission surface of the lens is arranged in amicrostructure and a function array to control the intermediate light reasonably, and then the light from the light source is differentiated and superimposed in an orderly manner, thereby solving the problem of uneven mixingof light transmitted through the lens.
Using the principle of calculus lens, the reflected light is differentiated to effectively mix light. Add a surface differential structure to the incident and exit convex surfaces, so that the transmitted light is evenly distributed, and the color is uniform.
According to the lighting industry's requirements for the power and size of common lamps, the tentative specifications of the standard model products ofthe chameleon series lenses are as follows:
