Abstract

The utility model discloses an LED (light emitting diode) bulb lamp, which comprises a lamp cap, a connecting seat, a radiator and a bulb housing sequentially from top to bottom. A radiating groove is arranged at the upper end of the connecting seat, the radiator comprises a heat sink and a radiating base, the heat sink and the radiating base are formed integrally, and through slots are arranged on the heat sink. The heat sink and the radiating base are formed integrally, so that heat conduction efficiency becomes higher, meanwhile heat is radiated from the radiating groove and the through slots by utilizing hot air rising according to the aerodynamics design principle, accordingly cross-ventilation is produced, and cool-heat conversion is accelerated.

Description

The LED bulb lamp

Technical field

The utility model relates to a kind of LED light fixture, especially relates to the LED bulb lamp.

Background technology

Along with the development of society and the raising of people's living standard, the LED bulb lamp is limited because of it is of fine quality, durable, energy-conservation, light is soft etc., will certainly substitute conventional incandescent bulb and power saving fluorescent lamps, being applied in the daily life more and more widely.But the LED bulb lamp produces a large amount of heats at work, and heat such as untimely the evacuation will influence light fixture service behaviour and service life.

It is low that the heat abstractor of existing LED bulb lamp exists structural strength, and consumptive material is many, adopts zero-clearance extrusion modling mode to connect between led light source and the radiator; Thermal resistance is bigger, and the radiator inner air can not circulate, and the heat that led light source produces is difficult to distribute; Driving power electronic devices and components and led light source are all had infringement, and reduction of service life and performance have had a strong impact on service life of LED bulb lamp; Therefore, be necessary to develop a kind of LED bulb lamp of improved high efficiency and heat radiation.

Summary of the invention

The utility model is the LED bulb lamp that a kind of high efficiency and heat radiation is provided to the defective that the above-mentioned background technology exists.

For realizing above-mentioned purpose; The utility model discloses a kind of LED bulb lamp; It comprises lamp holder, Connection Block, radiator and cell-shell from top to bottom successively, and said Connection Block upper end offers radiating groove, and said radiator comprises radiator and cooling base; Said radiator and cooling base are one-body molded, offer through-hole groove on the said radiator.

Further, said Connection Block lower end is provided with the threaded portion, and said radiator inner upper end cooperates said threaded portion to offer thread groove.

Further, said radiator is provided with some fin, and said fin becomes circle distribution in said radiator outer surface.

Further, said through-hole groove is circular hole or recessing shape.

In sum; The utility model LED bulb lamp is through adopting one-body molded mode to be connected said radiator and said cooling base, and heat conduction efficiency uprises, simultaneously according to the aerodynamic design principle; Utilize hot-air to rise; Heat distributes from radiating groove and through-hole groove, makes it produce cross-ventilation, quickens cold and hot conversion.

The specific embodiment

For further understanding characteristic, technological means and the specific purposes that reached, the function of the utility model, the utility model is described in further detail below in conjunction with the accompanying drawing and the specific embodiment.

Extremely shown in Figure 4 like Fig. 1; The utility model LED bulb lamp comprises lamp holder 10, Connection Block 20, radiator 30 and cell-shell 40 from top to bottom successively; Said lamp holder 10 is formed one with Connection Block 20 through riveted joint; Said Connection Block 20 upper ends offer radiating groove 21, and said Connection Block 20 lower ends are provided with threaded portion 22.

Said radiator 30 comprises radiator 31 and cooling base 32; Said radiator 31 adopts the die casting mode one-body molded with cooling base 32; Said radiator 31 is a hollow cone platform shape structure; Said radiator 31 set inside have LED power supply (figure does not show), and said radiator 31 inner upper end cooperate said threaded portion 22 to offer thread groove 33, and said radiator 31 is provided with some fin 34; 34 one-tenth circle distribution of said fin offer the through-hole groove 35 of circular hole or recessing shape in said radiator 31 outer surfaces on the said radiator 31; Said cooling base 32 is arranged at said radiator 31 lower ends, and said cooling base 32 is provided with led light source (figure does not show).Said radiator 31 is connected with said Connection Block 20 engagings, and said threaded portion 22 is connected with said thread groove 33 engagings, and said through-hole groove 35 is communicated with said radiating groove 21, and said cell-shell 40 is connected in said radiator 30 lower ends through the engaging mode.

When the utility model used, the heat that led light source produces was delivered on the radiator 31 through cooling base 32, because said radiator 31 is a hollow structure; According to the aerodynamic design principle; When radiator 31 temperature rose, radiator 31 Inside Air Temperatures also rose in the lump, and cold and hot air exchanges at radiating groove 21 and through-hole groove 35 places; Make it produce cross-ventilation, quicken cold and hot conversion; Increased area of dissipation through said fin 34 simultaneously, because said radiator 31 adopts one-body molded mode to be connected with said cooling base 32, thermal resistance is little, and heat conduction efficiency uprises.

In sum; The utility model LED bulb lamp is through adopting one-body molded mode to be connected with said cooling base 32 in said radiator 31, and heat conduction efficiency uprises, simultaneously according to the aerodynamic design principle; Utilize hot-air to rise; Heat distributes from radiating groove 21 and through-hole groove 35, makes it produce cross-ventilation, quickens cold and hot conversion.

The above embodiment has only expressed a kind of embodiment of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with accompanying claims.
