Problems solved by technology

[0004] In actual use, it is found that it is not enough to use only low color temperature LED lights or high color temperature LED lights in a specific place, which often brings many changes; if additional LED lights are installed, the utilization rate of the LED lights is low, wasting resources, increase cost
Moreover, the existing LED lights lack the type that can adjust both the color temperature and the brightness, and the LED lights with both functions need to be equipped with a specific switch. The internal structure of this type of switch is complicated, the cost is high, and the price is high. , not suitable for widespread use

Embodiment Construction

[0028] Such as Figure 1 to Figure 5 As shown, an LED lamp with adjustable dimming and color temperature includes a rectifier 1 and a logic control circuit 5. The rectifier 1 converts alternating current into direct current, simplifies the working circuit of the LED lamp, and is easy to use. The rectifier 1 and the voltage limiting protection circuit 2 are connected to each other, and the voltage limiting protection circuit 2 is as Figure 4 As shown, the voltage limiting protection circuit 2 includes a sampling part 12, a comparison part 13 and an output shaping part 14. The sampling part 12 uses a voltage dividing resistor R 0 , R 1 , R f To achieve voltage acquisition; VDD is the input voltage, V ref is the internal reference voltage; the resistance divided voltage collected by the sampling part 12 is compared with the reference voltage of the comparison part 13, and according to the comparison result, it is determined whether the voltage is not within the threshold volt...

Abstract

The invention discloses an LED lamp with adjustable light and color temperature, which includes a rectifier and a logic control circuit. The logic control circuit is connected with a resistance adjustment circuit. The output end of the resistance adjustment circuit is connected with a color temperature electronic switch group. The color temperature resistance switch group consists of Logic control circuit control, the output end of the color temperature electronic switch group is connected with a low color temperature LED lamp group and a high color temperature LED lamp group, the low color temperature LED lamp group and the high color temperature LED lamp group are connected in parallel, and the low color temperature LED lamp group includes low color temperature LED lamps The high color temperature LED lamp group includes high color temperature LED lamp sheets. In the present invention, the low color temperature LED lamp group and the high color temperature LED lamp group are respectively connected to the LED lamp, and the number of low color temperature LED lamp sheets and the number of high color temperature LED lamp sheets are controlled by the electronic switch group, thereby adjusting the color temperature of the LED lamp . At the same time, the resistance value of the access circuit is adjusted by means of the resistance adjustment circuit to realize the adjustment of the brightness of the LED light, and the design is ingenious.

Description

technical field [0001] The present invention relates to an LED lamp, in particular to an LED lamp that can adjust brightness and adjust temperature Background technique [0002] The basic structure of the LED lamp is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connected to the chip and the circuit board with silver or gold wires, and then sealed with epoxy resin around it to play a role. The function of protecting the inner core wire is finally installed to form a complete LED lamp. LED lights have the advantages of small size, low power consumption, long service life, high brightness, low heat and environmental protection. Can be used for table lamps, general lighting, stage lights, etc. [0003] LED lights mainly include two types: low color temperature LED lights and high color temperature LED lights. Low color temperature LED lights are also called cool color temperature LED lights. LED ligh...
