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

Abstract

The invention discloses an LED four-color light lamp based on a white light compensation technology, which belongs to the technical field of LED lamps.According to the scheme, the outer wrapping lampshade and the blue light lamp are started to work; the outerwrapping lampshade can be promoted to emit white light; meanwhile, the YAG fluorescent powder in the white light supplementing cover is irradiated by means of theblue light lamp; white light can be supplemented; along with temperature rise, ammonium chloride powder in the corrugated airbag ring can be promoted to be heated and decomposed into hydrogen chloride gas and ammonia gas; the sealing circular plate is pushed to move upwards; on one hand, the YAG fluorescent powder can be promoted to be gathered more densely; therefore, the light supplementing effect on the white light is improved; on the other hand, the expansion transparent bag strip can be promoted to extend, so that part of YAG fluorescent powder is promoted to enter the expansion transparent bag strip, the light supplementing range of white light is widened, the light supplementing effect is further improved, meanwhile, heat in the LED lamp holder can be absorbed by means of decomposition of ammonium chloride powder, and the possibility of damage caused by too high temperature in the LED lamp holder is reduced.

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
