The specific embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Referring to figs. 1 through Fig. 4, one embodiment of the LED bulb of a kind of high efficiency and heat radiation of the present utility model is proposed, be fixedly connected with successively from the bottom to top lamp holder, holder structure, LED light source assembly, be connected with the holder structure upper end open and be located at the outer diffuser of light source assembly, also comprise and be located in holder structure and the drive unit be electrically connected to light source assembly.
Holder structure comprises hollow lamp socket body 101, be fixedly arranged on the center of lamp socket body 101 and can insert the light source fixed leg 300 of LED light source assembly, the upper end open place of lamp socket body 101 medial surfaces is followed successively by annular short slot 102 and convex annular makes lamp socket body 101 medial surface opening parts stepped ringwise along 103, the annular side of short slot 102 and bottom surface are provided with some sections and are " L " font or the ventilation short slot 104 of shape in obtuse angle, and the quantity of ventilation short slot 104 is 1 to 6.Diffuser be fixedly arranged on convex annular along 103 with the junction of annular short slot 102, it is inner and outside that ventilation short slot 104 is communicated with diffusers.The center of ventilation short slot 104 is provided with projection 105, and projection 105 has increased the laminating fixed-area with diffuser, and diffuser is had to certain fixation.The diffuser of existing LED bulb is Seal Design, and radiating effect is not good, and the utility model makes the air of diffuser inside and outside air to be circulated by ventilation short slot 104 is set.
Between light source fixed leg 300 lateral walls and lamp socket body 101 madial walls, by some vent ribs 200, be connected and fixed, vent rib 200 connects light source fixed leg 300 and lamp socket body 101, heat on light source fixed leg 300 is delivered on lamp socket body 101 rapidly, and vent rib 200 increased the contact area with extraneous air, effectively accelerate the volume rate of heat dispation.In addition, form louvre post 201 between vent rib 200, air can carry out upper and lower convection current, accelerates the Air Flow of lamp socket body 101 peripheries, makes air-flow take away rapidly heat.
Light source fixed leg 300 lower ends are provided with the lower end cavity 301 that can insert drive unit, upper end is provided with the light source cavity 302 that can insert the LED light source assembly, the LED light source assembly comprises the circuit board of being close to light source cavity 302 bottoms, some LED lamp pearls of being located on circuit board and being electrically connected to drive unit, and the quantity of LED lamp pearl is 1 to 8.The top of lower end cavity 301 is provided with the first threading hole 303 and some the first heat radiation through holes 304, and the bottom of light source cavity 302 is equipped with the second threading hole 305 and some the second heat radiation through holes 306.
Be formed in one structure being made by Heat Conduction Material pottery or metal of holder structure.
When the LED bulb works, drive unit and LED lamp pearl send a large amount of heats and form the hot-air of HTHP.Because lamp socket body 101 and light source fixed leg 300 material good by heat conductivility are made, the part heat can pass by the sidewall of holder structure, and by some vent ribs 200, be connected and fixed between light source fixed leg 300 lateral walls and lamp socket body 101 madial walls, heat on light source fixed leg 300 is delivered on lamp socket body 101 rapidly, and vent rib 200 increased the contact area with extraneous air, effectively accelerate the volume rate of heat dispation.In addition, form louvre post 201 between vent rib 200, air can carry out upper and lower convection current, can rapidly the dissipation of heat on lamp socket body 101 and light source fixed leg 300 be gone out.
On the other hand, the three heat radiation through hole 307 of hot-air part in lower end cavity 301 from lower end cavity 301 sidewalls distributes, part from the second heat radiation through hole 306 of the first heat radiation through hole 304 and light source cavity 302 of lower end cavity 301 enter into the light source inner chamber and the heat that produces with LED lamp pearl together with form thermal air current and lead in the space between holder structure and diffuser, the hot-air part between holder structure and diffuser can be passed to outside by louvre post 201, and be " L " font or the ventilation short slot 104 of shape in obtuse angle owing to being provided with some sections on the side at annular short slot 102 and bottom surface, diffuser be fixedly arranged on convex annular along 103 with the junction of annular short slot 102, like this, just make air and the extraneous air of diffuser inside to be circulated by ventilation short slot 104, and the hot-air between holder structure and diffuser can also promptly be dispersed in extraneous air by ventilation short slot 104 in time, distributed in time the heat between diffuser and holder structure, the structure of high efficiency and heat radiation has extended the service life of LED bulb effectively like this.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
