Abstract
The invention relates to a full outdoor light-emitting diode (LED) lamp with a lens. The problems that a base made of phenyl-propanolamine (PPA) is adopted by a surface-mounted device (SMD) light-emitting diode (LED) lamp, and the lamp easily absorbs moisture to be failed are solved. The LED lamp comprises two pins, and a light-emitting chip; each pin consists of an upper main body and a lower main body; the top end of the upper main body of one pin is extended in a horizontal direction to form a platform; a reflection groove is depressed in the middle of the platform; the light-emitting chip is arranged in the reflection groove and is connected to the other pin through a conducting wire; the lower end of the lower main body of each pin is flanged in the horizontal direction to form a surface mount part; two pins are sealed and embedded in the lens; and the surface mount parts are extended out of the lens. The invention has the advantages that the full outdoor LED lamp solves the problem that the lamp easily absorbs moisture, and can be completely used outdoor; the pin is wider than a straight insertion LED pin, and has an electric conduction function and a good heat dissipation property; and the surface mount part of the lower end of the lower main body of each pin has the characteristics of a surface mount device of the SMDLED lamp and brings convenience to the surface mount of the LED lamp.
Description
Technical field
The present invention relates to a kind of light fixture, especially relate to a kind of full outdoor LED lamp that adds lens of moistureproof and waterproof.
Background technology
Because traditional SMD LED is a pedestal with the PPA material; This properties of materials is to be prone to moisture absorption suction, and with the caking property of casting glue be not fine, cause poor air-tightness; Be easy to make SMD LED damp failure; Can cause the dead lamp of SMD LED after making moist, at present the dead lamp major part of SMD LED is all because SMD LED makes moist and causes on the market, thereby SMD LED is difficult to accomplish that the open air goes.
Like Granted publication number is CN201562691U; Name is called the Chinese utility model patent of a kind of full-color SMD LED; It comprises support, chip, gold thread, and said gold thread connects the PPA plastic plate and the chip of support, and PPA plastic plate surface is provided with border circular areas; Said chip yi word pattern is arranged in the said border circular areas, the encapsulation glue with said Chip Packaging on the PPA of support plastic plate.Plastic plate in this utility model patent just is equivalent to substrate, and this plastic plate has PPA to make to form, and it has just had above-mentioned shortcoming: the moisture absorption that absorbs water easily, and bad with the encapsulation caking property of watering, be easy to make SMD LED damp failure.
Summary of the invention
The present invention solves existing SMDLED lamp to adopt PPA material pedestal, absorbs water the moisture absorption easily and causes the problem of dead lamp, and a kind of full outdoor LED lamp that adds lens of moistureproof and waterproof is provided.
Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals: a kind of full outdoor LED lamp that adds lens, comprise two pins, and be arranged on the luminescence chip on the pin; Said pin is made up of last main body and following main body two parts; The last main body top horizontal direction of a pin has extended to form a platform, is formed with reflective groove in the platform intermediate recess, and said luminescence chip is installed in the reflective groove; Luminescence chip is wired on the last main body of another pin; The lower end edge horizontal direction flange of main body forms the portion that mounts under the said pin, and two pin sealings are embedded in the lens, and the portion of mounting stretches out outside lens.LED lamp of the present invention has been removed the base part of traditional P PA material; And adopt direct insertion lens; Have only lens and pin bonding; Lens and pin have kept the bonds well property of straight cutting encapsulation like this, have solved the problem of traditional SMDLED moisture absorption suction, and the present invention can accomplish outdoor use fully.In addition, the feasible characteristic that has kept SMDLED lamp paster of the portion of mounting of the formation of the pin bottom among the present invention.
As a kind of preferred version, said lens are made up of the pedestal one of circular-arc top and direction, and the centering angle of said top circular arc is 50 degree ~ 120 degree.LED lamp lens of the present invention top centering angle can change as required, accomplishes that the far field is adjustable, and centering angle can be accomplished 50 degree, 100 degree, 110 degree or 120 degree usually.
As a kind of preferred version, said pin is flat strip, and the width of following main body is greater than the width of main body.It is wide that pin of the present invention is compared direct insertion LED lamp pin, and making pin both have conducting function has and have good heat dissipation characteristics.Descend main body wideer in addition, this makes that the portion of mounting is also wideer, and more convenient mounting descends the part of main body to be sealed in the lens in addition, makes that sealing is more fastening.
As a kind of preferred version, said lens are epoxy resin lenses.Lens are difficult for moisture absorption suction like this, simultaneously lens with hand over caking property better, make that LED light airtightness of the present invention is better.
Therefore, advantage of the present invention is: 1. removed the base part of traditional P PA material, and adopted direct insertion lens to seal mutually with pin, solved the problem of moisture absorption suction, made and can accomplish outdoor use fully; 2. pin is flat strip, and is wideer than direct insertion LED lamp pin, makes pin not only have conducting function but also have good heat dissipation characteristics; 3. main body lower end flange forms and mounts portion under the pin, has kept the characteristic of SMDLED lamp paster, makes things convenient for the LED lamp to mount.
