Lamp color temperature control device

The utility model provides a color temperature control device for a lamp, in particular to a lamp color temperature control device which has a color temperature switching function and can freely change the order of color temperature switching of the lamp.

According to the color temperature, visible light has important applications in the fields of photography, video recording, publishing, etc., and the color temperature of the light source is determined by comparing the color and theoretical thermal blackbody radiator. When operating, the standard black body is heated. When the temperature rises to a certain extent, the color of the black body begins to change gradually in the order of deep red, light red, orange yellow, white, and blue. When the color of a light source and the black body are the same, the black body is then The absolute temperature is called the color temperature of the light source, so the color temperature is defined by the absolute temperature K.

Color temperature changes have been widely used in LED lamps, but their brightness and color temperature have been fixed at the time of manufacture and cannot be adjusted. Therefore, it is necessary for manufacturers to prepare various bulbs of different brightness and color temperature for customers to select. Issues such as cost, capital, and space usage required for inventory.

In addition, because LED lights have a variety of color temperature display patterns, it is often necessary to be set to the same xenon lamp to emit multiple colors, or can be switched to different colors in sequence, so it is often necessary to install a plurality of LEDs of different color temperatures, and at the factory Set the order of color temperature changes at the time of installation or installation.

However, when the above-mentioned LED lamp with color temperature change is used, the following problems and defects are still to be improved:

First, in order to achieve a variety of color temperature changes, it is necessary to significantly increase costs and inventory.

Second, the color temperature of LED lamps has a low degree of freedom in order, which cannot be adjusted at any time according to the needs of users.

Therefore, how to solve the above problems and deficiencies in the past, that is, the applicants of the new type and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in view of the above-mentioned shortcomings, the applicants of this new type have collected relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, they have designed this color temperature switching function. And a new patent holder of the color temperature control device of the lamp that can freely change the color temperature switching sequence of the lamp.

The main purpose of the present invention is that the user can automatically memorize the selected color temperature without additional operations, and reset the color temperature to the first order color temperature switching sequence when the next time it is turned on.

Another main purpose of the present invention is to form at least three different color temperature variations using LEDs of two color temperatures and to control the brightness output.

In order to achieve the above object, the structure of the novel lamp comprises: a plurality of light-emitting component groups having different color temperatures, and the light-emitting component groups sequentially switch different light-emitting combinations by a light source control module to generate different color temperatures. The light source control module is electrically coupled to a microprocessor for controlling the light source control module, and electrically connected to the microprocessor and the switch module of the light source control module to detect the light fixture The signal of the opening and closing action is transmitted to the microprocessor, and the memory module electrically connected to the microprocessor is used to selectively record the state of the color temperature change of the lamp to reset the order of color temperature changes of the lamp; When the user operates the new type, the switch module detects the opening and closing action of the lamp, and the microprocessor drives the light source control module to switch the color temperature groups to different color temperatures, and when the user switches. The memory module automatically records the current color temperature state, and resets the order of the color temperature changes of the lamp, so that the color temperature state is changed to the first order, thereby allowing the user to start the lamp next time. Direct representation of the color temperature of the automatic recording state.

With the above technology, it is possible to achieve a breakthrough in the problems of high cost, high inventory, low color temperature change order, and inability to change the color temperature in response to user demand. Practical advancement of advantages.
