Abstract
The utility model provides a glass tube encapsulated LED lamp bulb, which can be suitable for the requirement of the high fire-protection rating. A light emitting diode LED is encapsulated in a sealed glass tube, an LED pin-out is outside the glass tube, and the front end of the LED in the glass tube is provided with a reflector. The utility model has the advantage of simple structure. The glass tube is used to encapsulate the utility model to cause the utility model to have the advantages of high fire-protection rating, good fire-protection performance and more safety and reliability in use. When the utility model emits the light, the light emitted form the front top end of the LED is partially reflected to the lateral face at the periphery to cause the LED lamp bulb can seemingly emit the light from the lateral face to overcome the defects of strong light at the front end of the LED and dark light at the lateral face at the periphery of the LED.
Description
Technical field
The utility model relates to a kind of LED bulb, especially is mainly used in the glass tube encapsulated LED bulb that fire-protection rating is had higher requirements.
Background technology
Existing LED lamp usually with epoxy resin as the appearance encapsulating material, its major defect is that fire protecting performance is poor, and general LED lamp has only the light of front end strong, the light of side is dark all around.Application at the LED lamp is increasingly extensive, its fire protecting performance is required today of improving day by day, and above-mentioned LED lamp can not satisfy its requirement.
The utility model content
The purpose of this utility model provides a kind of glass tube encapsulated LED bulb applicable to high fire-protection rating requirement.
The purpose of this utility model is achieved in that a kind of glass tube encapsulated LED bulb, is packaged with LED in the sealed glass pipe, and glass tube has the LED leading foot outward.
LED front end in the described glass tube is provided with reflector, and reflector can be spheroid or cone or many rhombohedreons.
The utility model is simple in structure, owing to the glass tube encapsulation, make this utility model have high fire-protection rating, fire protecting performance is good, uses more safe and reliable.
For requiring LED side luminous LED bulb purposes all around, for example decorate and use Christmans light string, can in this glass tube, reflector be set encapsulated LED bulb front end, when luminous, side around reflexing to the light portion that LED sinciput end-fire is gone out, the whole LED bulb is looked can lateral emitting, has overcome general LED and has had only front end light strong, all around the dark defective of side light.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is equipped with the structural representation of reflector for the utility model;
1 glass tube, 2 LEDs, 3 reflectors, 4 leading foots
Embodiment:
As shown in the figure, a kind of glass tube encapsulated LED bulb is packaged with LED 2 in sealed glass pipe 1, the glass tube 1 outer leading foot 4 that LED is arranged.Be about to LED2 and pack in the glass tube that an end round end seals, again glass tube other end sintering is sealed.
As shown in Figure 2, the LED front end in the described glass tube 1 is provided with reflector 3, and reflector 3 can be spheroid or cone or many rhombohedreons.When luminous, side around reflexing to the light portion that LED sinciput end-fire is gone out, the whole LED bulb is looked can lateral emitting.
Claims (3)
1, a kind of glass tube encapsulated LED bulb is characterized in that, be packaged with LED in the sealed glass pipe, glass tube has the leading foot of LED outward.
2, glass tube encapsulated LED bulb according to claim 1 is characterized in that the LED front end in the described glass tube is provided with reflector.
3, glass tube encapsulated LED bulb according to claim 2 is characterized in that described reflector is spheroid or cone or many rhombohedreons.
