Description

A kind of LED lamp bead

Technical field

It the utility model is related to lighting technical field, more particularly to a kind of LED lamp bead.

Background technology

LED full name are semiconductor light-emitting-diode, using made of semi-conducting material, being a kind of directly to convert electrical energy into Luminous energy, electric signal are converted into the luminescent device of optical signal.Its main feature is that low in energy consumption, high brightness, beautiful in colour, anti-vibration, service life The advantages that long (normal luminous 8-10 ten thousand hours), cold light source, be real " green illumination ", be widely used in lamp ornaments lighting, LED Large screen display, traffic lights, decoration, computer, electronic toy gift, interchanger, telephone set, advertisement, city brilliance engineering etc. are all More production fields.LED lamp bead is limited by own material, it, which shines, is affected by temperature especially big, the more high then luminous intensity of temperature Reduce, the poor luminosity that can not only influence of heat dissipation performance can also shorten the service life of lamp bead, in addition, general LED lamp bead by It is simpler in structure, so easy fragmentation, pull resistance be not high.

Utility model content

The technical problem to be solved by the embodiment of the utility model is, it can not only be influenced for lamp bead heat dissipation performance is poor The problem of luminosity can also shorten the service life of lamp bead, and the easy fragmentation of general LED lamp bead, and pull resistance is not high, it is proposed that A kind of LED lamp bead.

In order to solve the above-mentioned technical problem, the utility model embodiment provides a kind of LED lamp bead, which includes： Substrate, carrier base, chip and lens, carrier base are stacked on substrate, and the center of substrate and carrier base is inserted with heating column, leads The top of plume is at least above the surface of carrier base, and the bottom of heating column is enclosed equipped with multiple heat sinks, heat sink and base plate bottom Positive plate and negative plate between separated by insulating trip, grillage is installed on base plate bottom, its bottom is flushed with heat sink, is led It is provided with the top of plume and is installed on the spaced chip platform of carrier base, chip in chip platform, lens cap is penetrated in carrier base On.

Wherein, the bottom of heating column is flushed with base plate bottom.

Wherein, insulation strip is provided with the substrate between positive plate and negative plate, for separating positive plate and negative plate.

Wherein, die bond layer of silica gel is provided between chip and chip platform.

Wherein, two gold threads of chip are connected with positive plate and negative plate respectively.

Implement the utility model embodiment, have the advantages that：A kind of LED lamp bead of the utility model, inside sets core Piece platform and heating column, strong from heat dissipation performance, structure is fixed, and pull resistance is good, not easily broken.

Brief description of the drawings

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, drawings in the following description are only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, other attached drawings can also be obtained according to these attached drawings.

Fig. 1 is a kind of positive structure schematic of LED lamp bead provided by the utility model；

Fig. 2 is a kind of present invention looks up structural representation of LED lamp bead provided by the utility model.

Embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work All other embodiments obtained, shall fall within the protection scope of the present invention.

The utility model provides a kind of LED lamp bead, and it is provided by the utility model one to refer to Fig. 1 and Fig. 2, Fig. 1 The positive structure schematic of kind LED lamp bead；Fig. 2 is a kind of present invention looks up structural representation of LED lamp bead provided by the utility model.Should LED lamp bead includes：

Substrate 10, positive plate 11, negative plate 12, heat sink 13, insulating trip 14, insulation strip 15, carrier base 20, chip 30, Die bond layer of silica gel 31, lens 40, heating column 50, chip platform 51 and grillage 60.

This LED lamp bead includes substrate 10, carrier base 20, chip 30 and lens 40.

Carrier base 20 is stacked on substrate 10, and the center of substrate 10 and carrier base 20 is inserted with heating column 50.Heating column 50 Top be at least above the surface of carrier base 20, bottom is flushed with 10 bottom of substrate.The bottom of heating column 50 is enclosed to be dissipated equipped with multiple Backing 13, is separated between the positive plate 11 and negative plate 12 of 10 bottom of heat sink 13 and substrate by insulating trip 13.Positive plate Insulation strip 15 is provided with substrate 10 between 11 and negative plate 12, for separating positive plate 11 and negative plate 12.

Grillage 60 is installed on 10 bottom of substrate, its bottom is flushed with heat sink 13, and the top of heating column 50 is provided with and props up The spaced chip platform 51 of stand 20, chip 30 are fixedly installed in chip platform 51 by die bond layer of silica gel 31, chip 30 Two gold thread (not shown) is connected with positive plate 11 and negative plate 12 respectively.The cover of lens 40 is penetrated on carrier base 20.

The chip 30 of the LED lamp bead of the utility model is dissipated by being interspersed in the heating column 50 at 20 center of substrate 10 and carrier base Heat, in order to strengthen heat-conducting effect, 50 bottom of heating column is provided with multiple heat sinks 13, and chip platform 51 is set with the interval of carrier base 20 Put.The carrier base 20 that the grillage 60 and middle part that bottom is set are set plays the role of reinforcing to whole lamp bead, improves The pull resistance of lamp bead.
