Abstract

The utility model provides an integrally packaged LED daylight lamp which comprises a daylight lamp tube consisting of a glass lamp tube, a burner and pins, and an integrally packaged LED luminous element which consists of a printing circuit board, an LED chip and a plastic reflective cover which is provided with a reflective cavity; the printing circuit board is electrically connected with the pins through conductive wires, and the LED chip is welded directly on the printing circuit board which is covered by the plastic reflective cover with the reflective cavity, and each LED chip falls down into the correspondent reflective cavity; each LED chip is covered with a phospher batching layer and a round ball- shaped optical epoxy resin layer. The LED daylight lamp not only can have complete interchangeability with the current fluorescent tubes in external structures and achieve the goals of long service life, low energy consumption, high lighting efficiency and green environmental protection in production and use, but also can arrange more LED luminous chips in per unit area, and reduce the packaging cost of the LED luminous element to the greatest extent to lead to the cost to be closer to market requirements.

Description

A kind of integrated encapsulated LED fluorescent lamp

Technical field

The utility model belongs to the led light source lighting technical field.

Background technology

The glass lamp coated inner wall fluorescent material that the illumination of present fluorescent tube is generally adopted and in fluorescent tube the mode of filling mercuryvapour.The more original tungsten filament solid luminescence of this mode mode improves a lot on photoelectric transformation efficiency, extensively adopt in the whole world, but the pollution of mercury metal pair environment is well-known, meets socioeconomic environmental protection demand for development.

LED has been widely used in every field such as color lamp illumination, signal demonstration as a kind of advanced luminescent material, it is a kind of luminescent material of new and effective, environmental protection, but, be widely used in the general lighting field more and also have many technical problems how in conjunction with traditional lighting system.

Summary of the invention

The utility model purpose provides a kind of and existing fluorescent tube structure and all on all four LED fluorescent lamp of appearance and size, and adopt a kind of white light LEDs element of integrated encapsulation, not only can interchangeability completely be arranged on contour structures, realize long-life, low-power consumption, high light efficiency and target of environmental protection fully all in producing and using with existing fluorescent tube.And can in unit are, arrange more LED luminescence chip and reduce the packaging cost of LED white light element to greatest extent, thereby make this LED fluorescent lamp product more near the market demand.

The technical solution of the utility model is as follows:

A kind of LED fluorescent lamp, it has the lamp holder and the common fluorescent tube of forming of pin at glass lamp, two ends, at the built-in integrated encapsulated LED light-emitting component of glass lamp.

Integrated encapsulated LED element is made of printed substrate with an electronic circuit, led chip and plastic reflective lid with reflection cavity; Printed substrate adopts lead to be electrically connected with pin, led chip directly is welded on the printed substrate, the plastic reflective of band reflection cavity covers on single-clad board, each led chip falls in the corresponding reflection cavity one by one, on each led chip, be coated with fluorescent material batching layer, on the fluorescent material batching layer spherical shape optical resin layer arranged.

Described printed substrate is a strip, and there is the rubber contact mat both sides and glass lamp inwall contact site, with the position of fixing circuit board in glass tube, and avoids printed substrate to contact with the tube inner wall rigidity and causes damaging glass lamp.

Advantage of the present utility model:

1, utilizes the light source of semiconductor lighting material LED light emitting diode, can realize real long-life, low-power consumption, high light efficiency, non-maintaining as fluorescent lamp.

2, adopt glass lamp, than various organic optical materials better optical property is arranged all, and manufacturing cost is lower.

3, fluorescent tube can adopt the glass lamp material and the size of original fluorescent tube fully, need not apply any material in the glass lamp, the lamp holder of original size is still adopted on the fluorescent tube both sides, realize effective connection between printed substrate and the lamp holder with lead, make and the on all four LED fluorescent tube of existing fluorescent tube appearance and size, consistent with use habit and aesthetic habit that the user is traditional, accepted easilier by market.

4, the characteristic that in manufacturing and use, all has complete environmental protection.

5, adopt integrated encapsulated LED element can in unit are, arrange more LED luminescence chip and reduce the packaging cost of LED white light element to greatest extent, thereby make this LED fluorescent lamp product more near the market demand.

6, having cancelled former fluorescent tube must pull the trigger by high pressure, under different voltage status, must adopt rectifier, starter, the drive circuit that inverter etc. are complicated, by the electronic circuit that adopts different voltages to drive, be built on the printed substrate, be applicable to common 220V, the power supply of AC and DCs such as 110V or 36V, 24V, 12V.

The specific embodiment

Now further specify structure of the present utility model in conjunction with the accompanying drawings:

Referring to Fig. 1, this LED fluorescent tube adopts glass material to make fluorescent tube 1, adopts lamp holder 2 and the pin 3 consistent with conventional fluorescent fluorescent tube profile.Referring to Fig. 2, at the printed substrate 4 of fluorescent tube 1 built-in charged electronic circuit 6, integrated encapsulation White-light LED chip forms integrated encapsulated LED element on the printed substrate 4.Printed substrate 4 and connector 7 on the lamp holder 2 are fixed together, and printed substrate 4 adopts leads to be connected with pin 3 on the lamp holder 2, finishes the circuit connection.Printed substrate 4 is a strip, in conjunction with sectional view 3 as seen, printed substrate 4 both sides and glass lamp inwall contact site be rubber contact mat 8 fixedly, printed substrate is not contacted with tube inner wall generation rigidity can prevent that wiring board from damaging fluorescent tube, also can prevent the lamp holder far-end displacement of wiring board in fluorescent tube simultaneously.

Referring to Fig. 4, integrated encapsulation white light LEDs element is made of the plastic reflective lid 9 of printed substrate 4, led chip 11 and band circular hole reflection cavity 10, and printed substrate 4 is a single-clad board.Referring to Fig. 5, to cover on printed circuit board (PCB) 4 with the plastic reflective lid 9 of circular hole reflection cavity earlier, led chip directly welds on the wiring board, correspondence falls in each circular hole reflection cavity 10, then in circular hole reflection cavity 10, led chip 11 peripheral point annotate fluorescent material batching layer 12, click and enter spherical optical resin layer 13 sealing and curing again after fluorescent material batching layer 12 solidifies.
