Abstract
The utility model discloses an LED modulator tube. The LED modulator tube comprises a metal substrate support, wherein the metal substrate support is arranged in a glass lampshade, a plurality of LED chips are fixed on the metal substrate support, the glass lampshade is filled with heat conduction gas, and fluorescent powder evenly coats the inner wall of the glass lampshade. The LED modulator tube has the advantages that the facular problem caused by uneven light emission of a light source is solved, light losses caused in the conductive process of light are reduced, the lighting effect of the light source is improved, meanwhile, the service life of the LED modulator tube is prolonged, and the production cost and the manufacturing cost of the LED modulator tube are greatly reduced.
Description
Technical field
The utility model relates to a kind of LED fluorescent tube, belongs to the led light source technical field.
Background technology
In the present LED lighting field, the fluorescent tube of use is to be attached on the pcb board by several paster lamp pearls, adds in the pcb board outside that again the acrylic lampshade of a frosted forms.There is following problem in this LED fluorescent tube: 1, because the luminous meeting of a plurality of paster lamp pearl causes the integrated light source non-uniform light, thereby cause acrylic lampshade outside hot spot to occur, if will solve the hot spot problem, certainly will need the frosted lampshade with low-transmittance, so just reduce the light emission rate of light source, reduced light efficiency; 2, traditional LED fluorescent tube, air-tightness is bad, and the long-term airborne water vapour in back that uses can infiltrate paster lamp pearl inside, causes the dead lamp of light source; 3, traditional LED fluorescent tube also will carry out SMT processing behind lamp bead seal dress, increased the production process of fluorescent tube, has increased cost greatly.
The utility model content
Technical problem to be solved in the utility model is to overcome the problems referred to above, and a kind of LED fluorescent tube that can eliminate hot spot, improve light efficiency is provided, and prolonging lamp tube service life, reduces manufacturing cost.
The technical solution of the utility model is:
A kind of LED fluorescent tube, comprise the metal substrate support, it is characterized in that: described metal substrate support is installed in the glass lamp shade, and several led chips are fixedly arranged on the metal substrate support, falling heat-transfer gas in the described glass lamp shade, the glass lamp shade inwall is coated with fluorescent material equably.
Glass lamp shade described in the utility model is sealed at both ends.
Metal substrate support described in the utility model two ends are provided with the support both positive and negative polarity, and described support both positive and negative polarity exposes in the glass lamp shade outside.
Weld and be conducting to the support both positive and negative polarity by gold thread between the led chip described in the utility model.
Heat-conducting gas described in the utility model is compressed helium.
The beneficial effects of the utility model are:
1, be coated with fluorescent material in the glass lamp shade equably, and the light that single fluorescent material sends after being excited is very even, thereby has solved the inhomogeneous hot spot problem that causes of light source luminescent;
2, the light beam that sends of chip excitated fluorescent powder does not need the reflection through emission bowl and silica gel in the encapsulation lamp pearl, do not need refraction and reflection through acrylic frosted lampshade yet, but directly reflect away by glass lamp shade, solve the light loss problem that light causes in conductive process, improved the light efficiency of light source;
3, because glass lamp shade is sealed at both ends, the gold thread that therefore connects the support both positive and negative polarity can not be subjected to external environment influence when work, strengthened the reliability of LED fluorescent tube greatly, has prolonged service life;
4, with respect to the traditional fluorescent lamp pipe, the PPA support and the silica gel that do not need the paster light source in the employed former material of the utility model, do not need to carry out SMT processing yet, and can be directly connected on the corresponding driving power and use, directly the terminaloriented client sells, and greatly reduces manufacturing cost and selling cost;
5, since present stage support and the production technology of glass lamp shade very ripe, metal substrate can extend the support that is made into arbitrary dimension, integrated a plurality of led chip has arbitrarily satisfied the demand of different capacity.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1.
The specific embodiment
Now by reference to the accompanying drawings the utility model is further described:
As shown in Figure 1-Figure 3, a kind of LED fluorescent tube, comprise metal substrate support 1, several led chips 3 are fixedly arranged on the metal substrate support 1, metal substrate support 1 is installed in the glass lamp shade 2, glass lamp shade 2 sealed at both ends is full of compressed helium as heat-conducting gas 4 in the glass lamp shade 2, glass lamp shade 2 inwalls are coated with fluorescent material 7 equably.Metal substrate support 1 two ends are provided with support both positive and negative polarity 5, and support both positive and negative polarity 5 exposes in glass lamp shade 2 outsides.Weld and be conducting to support both positive and negative polarity 5 by gold thread 6 between the led chip 3.
The operation principle of LED fluorescent tube described in the utility model is luminous by the led chip 3 that is fixed on the metal substrate support 1, thereby excites the fluorescent material 7 of glass lamp shade 2 inwalls to produce light beam again.The light that sends after single fluorescent material 7 is excited is very even, solved the hot spot problem, and do not need through launching the reflection of bowl and silica gel, do not need refraction and reflection through acrylic frosted lampshade yet, but directly reflect away by glass lamp shade 2, reduce light loss, improved the light efficiency of light source.
When manufacturing LED fluorescent tube described in the utility model, earlier led chip 3 is fixed on the metal substrate support 1, make all led chips 3 and 5 conductings of support both positive and negative polarity by gold thread 6 welding again, then support integral body is filled in the glass lamp shade 2, glass lamp shade 2 is sealed at both ends, in glass lamp shade 2, charge into compressed helium at last, serve as the heat-conduction medium of inner led chip 3, metal substrate support 1 and outer glass lampshade 2.Compare the making of traditional fluorescent lamp pipe, do not need PPA support and the silica gel of paster light source, also do not need to carry out SMT processing, greatly reduce manufacturing cost.
