Problems solved by technology

[0003] At present, there are basically two types of fire emergency lights in the market. One is to use 8~12 plug-in LED light-emitting tubes. The problem with this kind of lights is that the power consumption is too large, and the lighting time in emergency is too short. ; The service life is not long, easy to decay
The second type is multiple SMD lamp beads: the cost of this product is more expensive; the power consumption is still large, and the brightness of the lamp is not enough
[0004] The existing technology is that there are three light-emitting chips in a single lamp bead, and its luminous efficiency is 125LM / W. It is driven by 60MA during operation, and the luminous flux is 22-24LM; the existing technology is driven by sufficient current, and its current value is close to that of the lamp bead. The upper limit, the amount produced will easily attenuate the lamp beads; in the prior art, each fire emergency product needs to use more than 3 lamp beads to meet its national standard requirements

Abstract

The invention belongs to the technical field of light-emitting components, and particularly relates to an LED which comprises a support, a light-emitting crystal, a gold line, a power supply access end, a fluorescent powder layer and a nylon layer, wherein the light-emitting crystal is bonded on the support; the power supply access end is electrically connected with the light-emitting crystal through the gold line; the light-emitting crystal is coated with the fluorescent powder layer; and the fluorescent powder layer is surrounded by the nylon layer. By virtue of the light-emitting crystal arranged on the support, the light efficiency is improved, and the production cost and the power consumption are reduced; and one the basis of the use of three light beads originally, one light bead is reduced, the service lives of the light beads are prolonged, and the energy-saving and electricity-saving effects are achieved. Besides, the invention further discloses a manufacturing method of the LED.

Description

technical field [0001] The invention belongs to the technical field of light-emitting elements, and in particular relates to a light-emitting diode and a manufacturing method thereof. Background technique [0002] A light emitting diode (Light Emitting Diode, LED) is a semiconductor element that converts electric current into light of a specific wavelength range. Light-emitting diodes can be widely used as light sources in the field of lighting because of their advantages such as high brightness, low operating voltage, low power consumption, easy matching with integrated circuits, simple driving, and long life. [0003] At present, there are basically two types of fire emergency lights in the market. One is to use 8~12 plug-in LED light-emitting tubes. The problem with this kind of lights is that the power consumption is too large, and the lighting time in emergency is too short. ; The service life is not long, easy to decay.
