Abstract

The invention discloses a silicon-controlled dimming and color temperature changing downlight circuit. The silicon-controlled dimming and color temperature changing downlight circuit comprises an LEDdriving module, wherein the LED driving module is used to provide driving current for an LED; an LED load color temperature selection switch module is connected to the LED driving module; a Vs terminal of the power selection switch module is connected with the LED driving module; a negative pole of a third diode is connected to a power supply end through a seventh resistor; the LED load color temperature selection switch module is connected to a positive pole of an LED load input terminal; current firstly passes through a first three-gear changeover switch; and the LED load color temperature selection switch module comprises the first three-gear changeover switch. Through adoption of the silicon-controlled dimming and color temperature changing downlight circuit disclosed by the invention,a manufacturer can prepare materials conveniently; a seller can place an order better; one lamp can have multiple choices, and is convenient for a user to mount; the multiple needs of the user are met at the lowest cost; the cost is lowered greatly; and the life of a product is optimized.

Description

technical field [0001] The invention relates to the technical field of LED dimming, coloring, and temperature equipment, in particular to a thyristor dimming, coloring, and temperature downlight circuit. Background technique [0002] LED is widely used in various lighting and decoration fields. With the improvement of LED application technology, the dimming of a single lamp or the color temperature of a single lamp is far from meeting people's needs, but to pursue more diversification. , More convenient and versatile dimming and color temperature downlights. The emergence of a practical lamp with 3 brightness and 3 color temperature options not only optimizes the cost of materials and personnel at the manufacturing end, but also facilitates inventory at the sales end and improves user experience. At present, wifi / bluetooth and other control devices are used in the market to adjust power, dimming and color adjustment, which is costly and cumbersome for users to operate. For...
