Abstract

The utility model discloses a pure-green-light solid luminous lamp belonging to the field of luminous tube lighting source, more specifically, belonging to the manufacturing field of the LED solid lamp. An InGaN purple light diode chip 3 is coated with aluminate fluorescent powder 2 activated by the rare earth and is covered by a resin cap 1, then a pure-green-light LED 5 is gained. The pure-green-light LED 5 is enchased on a column type lamp socket 6, and a dust cover 7 is arranged outside the pure-green-light LED 5. The number of a plurality of diodes is decided according to the luminous request, and the diodes working in series or in parallel. The operating voltage is 3-30 volt. The utility model widens the application area of the purple light diode, and the produced column type green solid lamp adds the new type to the light source of the luminous tube. The color of the green solid lamp is purer than the traditional green incandescent lamp, and the green solid lamp can save the energy.

Description

A kind of solid luminous lamp of pure green glow

Technical field: the utility model belongs to luminous tube lighting source field, specifically belongs to the light-emitting diode solid state lamp and makes the field.

Background technology: the present light-emitting diode solid state lamp of selling all kinds of colors on the market has varied, and most of lamps are all worked in the single tube mode, or uses as number demonstration, informative advertising screen and all kinds of traffic lights.It is investigated that the solid material that can directly send green glow at present has GaP, InGaN, because GaP material light conversion efficiency is low, the green glow pipe brightness of making is low, and few people produce at present.InGaN material light conversion efficiency height, the green glow pipe brightness height of making, but the market price is very high, comes into operation seldom.And the pure green LED production cost of making through the fluorescent material conversion with InGaN violet light diode chip only is 1/3 of InGaN green glow pipe.

Utilization coated light-emitting phosphor conversion regime on light-emitting diode chip for backlight unit obtains another light, existing before this people's practical application.

Summary of the invention: the purpose of this utility model is to utilize the violet light diode chip that the InGaN material goes out coated fluorescent material converts pure green LED to and makes column type green solid lamp through the surface.

Rare-earth activated aluminate fluorescent powder 2 backs of coating cover with resin cap 1 on InGaN violet light diode chip 3, obtain pure green led 5, and described pure green led 5 is embedded on the column type lamp socket 6, and there is a dust cover 7 outside.Quantity is according to a plurality of diode serial or parallel connection work of luminous requirement decision, and operating voltage is between 3～30 volts.

This utility model has been widened the violet light diode range of application, and the column type green solid lamp of making has increased new varieties for the luminous tube light source.It is purer, energy-conservation than traditional green incandescent lamp color.The pure green solid lamp life-span is long, color is pure, acid and alkali resistance, shockproof, the visual angle is broad.

Description of drawings: Fig. 1 is pure green light emitting diode construction figure; Fig. 2 is pure green solid luminous lamp schematic diagram; Situation when Fig. 3 connects for diode; Situation when Fig. 4 is the diode parallel connection; Fig. 2 is a Figure of abstract.

Embodiment:

Embodiment 1: the rare-earth activated aluminate fluorescent powder of coating on InGaN violet light diode chip, obtain pure green led, make solid state lamp, 3 volts of operating voltages with being fixed on after 10 such light-emitting diode parallel connections on the column type lamp socket that dust cover arranged.

Embodiment 2: the rare-earth activated aluminate fluorescent powder of coating on InGaN violet light diode chip, obtain pure green led, make solid state lamp, 30 volts of operating voltages with being fixed on after 10 such light-emitting diodes series connection on the column type lamp socket that dust cover arranged.

Embodiment 3: the rare-earth activated aluminate fluorescent powder of coating on InGaN violet light diode chip, obtain pure green led, make solid state lamp, 3 volts of operating voltages with being fixed on after 20 such light-emitting diode parallel connections on the column type lamp socket that dust cover arranged.
