Abstract

The utility model relates to an LED bulb, which comprises a lamp holder, a lamp socket and an LED light source, wherein one side of the lamp socket is fixed with the lamp holder, and the other side of the lamp holder is fixed with a heat radiator, and the LED light source is arranged on the heat radiator, wherein the LED light source comprises an LED lamp bead and an LED mounting plate. The utility model is provided with the special heat radiator, the LED light source is directly connected with the heat radiator, and generated heat energy can be timely exhausted through the heat radiator, therefore the utility model has excellent heat radiation and free damage, and solves the problem that a current LED bulb is easy to damage caused by poor heat radiation.

Description

The LED bulb

Technical field

The utility model relates to lighting, and relating in particular to LED is the bulb of light source.

Background technology

The characteristics that the LED bulb is long with its life-span, power consumption is low progressively replace traditional incandescent lamp bulb.Existing LED bulb generally is made of lamp holder, lamp socket, led light source and lampshade.Its lamp socket adopts metal, and the double radiator of doing in order to strengthen radiating effect, radiating fin can also be set, but its thermolysis is still limited on metal lamp holder, and the LED bulb often damages because of the bad heat savings formation high temperature that causes that dispels the heat.

The utility model content

The utility model has carried out research and has improved at the bad flimsy problem of above-mentioned LED bulb heat radiation, provides a kind of heat radiation good non-damageable LED bulb.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

The LED bulb comprises lamp holder, lamp socket, led light source, the fixedly connected lamp holder of a side of lamp socket, and the opposite side of described lamp socket is fixedly connected with radiator, and led light source is arranged on the radiator, and described led light source comprises LED lamp pearl and LED installing plate.

Further, described radiator is discoid; The fin that the arranged outside of described discoid radiator is radially extended; Described discoid radiator and described fin are integrative-structures.

Further, the luminous angle of described LED lamp pearl is 10 °～180 °.

Again further, the bottom of described radiator is provided with lampshade.

Technique effect of the present utility model is:

1. lamp socket is provided with special radiator, and led light source directly is connected with radiator, and the heat of generation can shed by radiator in time;

2. radiator is discoid, and its arranged outside has the fin that radially extends, and has enlarged area of dissipation, and radiating effect is better;

3. discoid radiator and fin are integrative-structures, have reduced the manufacturing cost of radiator;

4. the luminous angle of the LED lamp pearl of Cai Yonging is 10 °～180 °, and the field of illumination of LED bulb can be selected in this scope, LED bulb wide in variety.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.

See Fig. 1, the utility model comprises lamp holder 1, lamp socket 3, led light source.

See Fig. 2, lamp holder 1 adopts the screw socket of standard incandescent bulb, and the middle part of lamp holder 1 is an electrical pickoff 13, is insulator 12 around it.Lamp holder 1 also can adopt the bayonet socket of standard incandescent bulb.

See Fig. 1, Fig. 2, lamp socket 3 is manufactured by insulating materials, for example can be by injection molding, and its termination is provided with screw thread, is threaded with lamp holder 1.Lamp socket 3 also can pass through the bonding alternate manner that waits fixedlys connected with lamp holder 1.Lamp socket 3 inside are cavity, and AC/DC conversion constant-current source 10 is set, and constant-current source 10 is the commercially available universal product.The input of constant-current source 10 is electrically connected with electrical pickoff 13 and shell on the lamp holder 1 respectively by lead 11; The output of constant-current source 10 is electrically connected with led light source by the through wires hole 7 that lead 6 passes on the radiator 4.

Referring to Fig. 1 and Fig. 3, lamp socket 3 is provided with three screw holes 2, fixedlys connected with the radiator 4 of bottom by screw 15.See Fig. 2, the lower thread of radiator 4 is connected with lampshade 5.Lampshade 5 usefulness transparent materials such as acrylic etc. are made.Lampshade 5 and the bottom that can be connected to radiator 4.

See Fig. 2, led light source is arranged on the radiator 4.Led light source comprises LED lamp pearl 8 and LED installing plate 9, and the quantity of LED lamp pearl 8 is at least one, can brightness as required be in series by a string LED lamp pearl 8, and the luminous angle of LED lamp pearl 8 can be adopted 10 °～180 °.LED installing plate 9 can adopt commercially available aluminium base Copper Foil insulation board.

See Fig. 3, radiator 4 is discoid, the fin 14 that the arranged outside of discoid radiator 4 is radially extended, and fin 14 is radial.Discoid radiator 4 can be the branch body structure with fin 14, also can be the integrative-structure that is formed by the aluminium section bar extruding.
