A LED four-color light lamp based on white light compensation technology

Abstract

The invention discloses an LED four-color light lamp based on white light compensation technology, which belongs to the technical field of LED lamps. The scheme works by starting the outsourcing lampshade and the blue light lamp, which can promote the outsourcing lampshade to emit white light, and at the same time use the blue light lamp to supplement the light cover. The YAG fluorescent powder inside can supplement the white light. As the temperature rises, the ammonium chloride powder in the corrugated airbag circle can be thermally decomposed to form hydrogen chloride gas and ammonia gas, and push the sealing disc to move. On the one hand It can promote the YAG phosphor to gather more densely, thereby improving the light supplement effect for white light. On the other hand, it can also promote the expansion of the transparent capsule, so that part of the YAG phosphor can enter into the expanded transparent capsule, thereby improving the contrast of white light. The range of supplementary light further improves the supplementary light effect. At the same time, with the help of the decomposition of ammonium chloride powder, it can also absorb the heat in the LED lamp holder, thereby reducing the possibility of damage due to excessive temperature in the LED lamp holder.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an LED four-color light lamp based on white light compensation technology. Background technique [0002] 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 sealed with epoxy resin around it to protect the inner core wire. The role is to install the shell at last, so the LED lamp has good shock resistance. It is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor chip, one end of the chip Attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin. [0003] Semiconductor wafer...

Problems solved by technology

[0004] In some scene lighting places, it is often necessary to change the luminous color of the lamp. Usually, the RGB three-color mixture is used to form white light. However, when the lamp is converted into white light, the white light of this three-color mixture has low luminous efficacy and poor white light effect. Defects
