Description

  The present invention relates to a full-color flashlight, and in particular, by combining a full-color LED module that includes LEDs of different wavelengths with the control circuit module, it provides multi-colored light and at the same time changes the color of the light, lights up and flashes with a function switch. Involved in full-color flashlight with high power light-emitting diode to control type.

  Many flashlights using light emitting diodes (LEDs) that are found in daily life are only one color of light, for example, white, red, blue, green, yellow, and other light colors. There are also flashlights that use two-color LEDs because one color is too monotonous, for example, the light color is white plus green, white plus blue, but this is also a flashlight that is simply a conventional single-color LED In addition, another color of light is added, and consumers have to buy multiple flashlights depending on the time and circumstances. Therefore, a flashlight using three-color LEDs has been devised, and for example, the colors of light are enriched by combining red, green and blue ones.

However, in the flashlight using the three-color LED as described above, it is difficult to provide white by mixing light colors evenly. There are six red LEDs 81, six green LEDs 82, and six blue LEDs 83 (see Fig. 8), but these flashlights alone provide three colors of red, blue and green light. However, when it is desired to produce white, red, green, and blue must be lit at the same time. At this time, red, green, and blue spots appear in the mixed colors, and the desired white is obtained. The situation that is not possible is seen. Even in light other than red, green, and blue, for example, pink, purple, and amber, an ideal color mixture is not achieved, and red, green, blue, and so on tend to be sparse. Therefore, even a flashlight using three-color LEDs cannot actually provide multi-colored light due to the mixed color effect, and only three colors can be used normally. The same applies to other colors other than the above three colors. Thus, it can be said that the color mixing process is not ideal.
Therefore, in light of the above-mentioned drawbacks, various colors such as white, pink, blue, orange, purple, and amber can be obtained by mixing light from red, green, and blue LEDs using advanced light color mixing technology. At the same time, a full-color flashlight using a high-power light-emitting diode of the present invention that can be used for various purposes is provided by adding functions of lighting and blinking to enhance practicality and application.

  Consists of full-color light emitting diode modules, light emitting diode modules using different wavelengths, control circuit modules, functional switches, batteries, cylinders, etc. The light source uses light emitting diodes of two or more different wavelengths, for example, red, green, blue Or high-power LED dies in three colors such as yellow, green, blue, etc., providing bright light in a small volume, ie one high-power LED (1 watt), 0.05 In addition to providing the brightness of 20 watt LEDs and realizing a small size due to its small volume, the installation position of the three color light sources is almost one point, so various colors with ideal quality Light is provided, but for the purpose of color mixing, a light diffusing agent is mixed in the light transmitting body in front of the die to diffuse and interlace the light to make the light visible to the naked eye a beautiful color. Provides light of various colors such as purple, azure and pink, which were difficult to realize.

  According to the present invention, because the volume of high-power LED dies with different wavelengths is small, the distance between them is very close during installation, and since these are light sources that are close to a single point when lit, It is possible to provide light, and in the translucent body at the tip of the die, by providing a light diffusing agent for color mixing of light, light emitted from chips of different colors is diffused and mixed, and an ideal white Alternatively, it is possible to provide other colors that are mixed colors, and further enhance the practicality by executing color switches and lighting, blinking modes, etc. with function switches, and for various applications depending on time and place The objective of providing a wide range of ideal light sources is achieved.
