Abstract

The utility model relates to a light-emitting diode (LED) bulb lamp, which is composed of a lamp casing, lamp beads, an aluminum substrate and a driving power supply assembly. The lamp casing is composed of a die-casting aluminum lamp cup, a glass lamp cover and a brass lamp holder. A light source adopts the surface mount type LED lamp beads, and the power supply is a voltage reduction type isolation constant current power supply. The LED bulb lamp adopts the die-casting aluminum lamp cup to conduct heat dissipation, a heat dissipation groove is arranged on the lateral wall of the lamp cup and comprises a plurality of radiating fins, so that the lamp cup is large in radiating area. Radiating holes are arranged in the middle of the aluminum substrate and form air convection with a cavity inside the lamp cup, so that radiating methods that the LED light source conducts heat dissipation in air convection mode are increased, junction temperature of an LED is effectively reduced, and reliability of the LED bulb lamp is greatly improved. The LED bulb lamp adopts the solid state cold light source LED as the lighting light source, thereby saving energy and power and being environment-friendly.

Description

A kind of LED bulb lamp

Technical field

The utility model relates to a kind of LED bulb lamp, particularly has high efficiency and heat radiation LED channels bulb lamp.

Background technology

The LED bulb lamp is on the basis of conventional incandescent bulb, to produce.In order to meet present interfaces and people's use habit, the LED bulb lamp has imitated the profile of incandescent lamp bulb.Its shortcoming is that area of dissipation is little, and heat dissipation channel is narrow, influences the junction temperature of LED, and then influences the LED luminous efficiency.

Summary of the invention

The utility model provides a kind of high efficiency and heat radiation LED channels bulb lamp that has.

To the defective that present LED bulb lamp exists, a kind of LED bulb lamp that the utility model provides adopts the die casting aluminium Lamp cup to dispel the heat, and this Lamp cup side wall surface has radiating groove, comprises a plurality of fin, and area of dissipation is big.The cavity that Lamp cup is inner and the passage mutual conduction of sidewall, the heat that led light source is distributed conducts on the heat radiation Lamp cup fast.Be provided with louvre in the middle of the aluminium base, the cavity inner with Lamp cup forms cross-ventilation, increased the heat radiation approach that led light source dispels the heat with cross-ventilated mode, reduced the junction temperature of LED effectively, greatly improved the reliability of LED bulb lamp.What the LED bulb lamp adopted is glass lamp shade, makes the light that penetrates have enough intensity, and light is evenly not dazzling.What power unit adopted is that buck is isolated the constant-current supply assembly, has the advantage that volume is little, reliable, efficient is high.Simultaneously, the bulb lamp interface adopts the design of E27 type screw socket, meets the existing interface size, need not to change convenient the installation.

In order to realize above-mentioned task, the utility model adopts following technical solution:

Have high efficiency and heat radiation LED channels bulb lamp, comprise by the big die casting aluminium Lamp cup of area of dissipation, aluminium base, buck isolation constant-current supply assembly, a group of SMD white LED lamp pearl, glass lamp shade and lamp holder mounted thereto and forming.

Below in conjunction with accompanying drawing the utility model is further described.

The specific embodiment

Concrete enforcement has following step:

1, successively be welded to aluminium base on according to lamp pearl position on the aluminium base adopting surface mounted LED lamp pearl;

2, aluminium base is fixed on the die casting aluminium heat radiation Lamp cup;

3, buck is isolated the constant-current supply assembly and be fixed in the heat radiation Lamp cup inner chamber, power supply one brings out line and links to each other with aluminium base, and the other end links to each other with lamp holder;

4, lamp holder is buckled in heat radiation Lamp cup bottom;

5, glass lamp shade is installed in heat radiation Lamp cup top.

This LED bulb lamp adopts the design of E27 type screw socket, can be directly installed on the bulb lamp interface.After the energising, alternating current converts the constant current direct current to through buck isolation constant-current supply and supplies power to adopting surface mounted LED, and its white light that sends penetrates through glass lamp shade, and emission angle reaches 180 degree.

Because what the heat abstractor of this bulb lamp adopted is to have radiating groove, the die casting aluminium Lamp cup that contains a plurality of fin dispels the heat, and area of dissipation is big, and heat dissipation channel is unobstructed.Simultaneously, be provided with louvre in the middle of the aluminium base, the cavity inner with Lamp cup forms cross-ventilation, increased the heat radiation approach that led light source dispels the heat with cross-ventilated mode, can make LED remain the highest luminous efficiency

Because the employing of glass lamp shade makes the light that penetrates have enough intensity, light is evenly not dazzling.This lamp lamp lamp holder adopts the design of E27 type screw socket, can be directly installed on the bulb lamp interface, and both convenient and practical, time and labour saving, cost-saved again.
