Embodiment Construction
[0013] see Figure 1 ~ Figure 3 , a composite light source of the present invention, is characterized in that, comprises the cylindrical base 1 that is provided with central hole, is provided with white light LED6 at the center of the bottom end of base 1, is provided with white light condenser lens 5 above white light LED6 . On the top of the base 1, there are eight single-color LEDs 2 uniformly distributed along the circumference. Each single-color LED 2 converges to the central reflector 4 through the single-light condenser lens 3 placed in front of it, and is reflected by the reflector 4. Function, all the monochromatic light is added to the white light emitted by the white LED, and together form a composite light source, which is emitted from the small hole at the top of the reflector.
[0014] The reflector 4 is an octagonal pyramid-shaped aluminum-plated ultraviolet intensified reflector composed of eight sides, and each side corresponds to one of the monochromatic LED...

Abstract
A compound light source is characterized in that it includes a cylindrical base with a central hole, a white light LED is arranged at the center of the bottom end of the base, and a white light condenser lens is arranged above the white light LED; There are eight monochromatic LEDs evenly distributed along the circumference, and each monochromatic LED is converged to the central reflector through the single-light condenser lens placed in front of it, and all the monochromatic light is added to the white light through the reflection of the reflector. Among the white light emitted by the LEDs, they together form a composite light source and emit from the small hole at the top of the reflector. The beneficial effect of the present invention is: a white high-power LED is combined with eight monochromatic lights, which can save a lot of tubes, and the wavelength of this composite light source almost covers the biochemical analyzers required by most manufacturers. The wavelength of the light source has a high promotional value.
Description
technical field [0001] The invention relates to a composite light source, which is mainly used as a light source in a biochemical analyzer. Background technique [0002] In biochemical analyzers, tungsten-halogen lamps and deuterium lamps are usually used as light sources, but both have disadvantages. First, the lifespan is not long enough, and replacement is very troublesome. However, the power supply of deuterium lamps is high-voltage power supply, which is very expensive. Water cooling of tungsten-halogen lamps is also a big problem. For a long time, people have been looking for a light source that can meet the entire life cycle and can be used. It does not need to be replaced, and there will be no problems caused by the replacement, and there is no trouble of replacement; no heat dissipation is required, and there is no complicated mechanism for water cooling. Of course, there will be no stability problems caused by poor heat dissipation; there is no complicated power s...
