Description

A kind of straight barrel type LED light fixture

Technical field

The utility model relates to LED field of light fittings, specifically, specially refers to a kind of straight barrel type LED light fixture.

Background technology

LED be called as the 4th generation lighting source or green light source, along with the development of LED, LED is energy-conservation owing to having, power saving, high efficiency, the reaction time is fast, life cycle is long and not mercurous, has the advantages such as environmental benefit and enjoys the concern of all circles.At present, LED is widely used in the fields such as various instructions, demonstration, decoration, backlight, general lighting and urban landscape.Existing LED adopts the structural design of single light source too much, and stablizing of whole lampshade is inadequate.In addition, also there is following defect in existing LED light fixture:

1. support is connected by wire with PN junction, causes current spread speed excessively slow.

2. the structural design of support, sapphire and PN junction is improper, causes in complex manufacturing.

3. traditional production technology is not reverse installation process, the support that need vary in size and PN junction, and therefore the positive and negative electrode of whole LED chip varies in size, and affects service life.

Utility model content

The purpose of this utility model is for the deficiencies in the prior art, provides a kind of straight barrel type LED light fixture, to address the above problem.

The technical problem that the utility model solves can realize by the following technical solutions:

A kind of straight barrel type LED light fixture, comprises radiating cylinder body, light-passing board, base and LED chip; On described base, radiating cylinder body is installed, the inside of radiating cylinder body offers cell body, and LED chip is installed in cell body, is provided with light-passing board in the end of cell body; Described LED chip comprises the first support, the second support, conductive adhesive, PN junction, sapphire and fluorescent material; Described the first support and the second support are used separately as in P-type semiconductor and N-type semiconductor; Near-end at the first support and the second support scribbles conductive adhesive, the two ends of described PN junction bottom are connected with the first support and the second support by described conductive adhesive respectively, sapphire is installed on PN junction, described sapphire bottom end face is connected with the end face of PN junction, and on sapphire top, end face scribbles layer of fluorescent powder.

Further, described PN junction comprise the Part I that is connected with the first support, with the Part II that the second support is connected, the size shape of described Part I and Part II is identical.

Further, described the first support is identical with the size and shape of the second support.

Further, described conductive adhesive is alloy tin cream.

Compared with prior art, the beneficial effects of the utility model are as follows:
