Abstract

The utility model discloses an LED light bulb. A lamp shell is provided with an LED chip as a luminous source and a PCB, and the PCB is encapsulated in the lamp shell through pouring silica gel; the LED chip is fixedly arranged on the PCB; and four abreast arranged connecting contacts are arranged on the bottom surface of the PCB, and the LED chip is electrically connected with the four connecting contacts. The LED light bulb is rapidly manufactured and is stable and durable by adopting the LED chip as the luminous source. Because the four parallel connecting contacts are adopted, the LED light bulbs are conveniently and stably inserted when connected into a lamp string, thereby realizing the colorful change of colors.

Description

A kind of LED bulb

Technical field

The utility model relates to a kind of LED bulb.

Background technology

LED is the another emerging light source after incandescent lamp, gas-discharge lamp as the light emitting semiconductor device of solid luminescence.Since its compare with ordinary incandescent lamp have the life-span long, radiationless, anti-impact force is strong, bright in luster and low in power consumption, belongs to energy-conservation environmental protection lighting source, therefore, adopted more and more widely by light decoration circle.

Simultaneously, national governments are are all researching and developing the LED technology with energy savings.Especially the C7-E12-5W incandescent lamp bulb of using as decorative chain is because its high energy consumption, low light efficiency, service life is short and allow prestige and step back.If can adopt led light source replaced C 7 incandescent lamp bulbs to carry out large-scale decorative lighting, saves energy widely then.

The utility model content

At defective that exists in the prior art and deficiency, the purpose of this utility model provides a kind of high light efficiency that can be used for common decorative lighting, longevity, energy-conservation, low-cost, LED bulb that multicolour changes.

In order to achieve the above object, the utility model proposes a kind of LED bulb, comprise lamp housing and lamp socket, described lamp socket and lamp housing snapping; It is characterized in that, be provided with led chip in the described lamp housing as light emitting source; Be provided with pcb board in the described lamp housing, described pcb board passes through the silica gel embedding in described lamp housing; Described led chip fixedly install with described pcb board on; Described pcb board bottom surface is provided with four connecting terminals that are arranged side by side, and described led chip is electrically connected described four connecting terminals.

Preferred as technique scheme, described pcb board is provided with solid glue groove, described led chip is fixed in the described solid glue groove, and by the transparent silica gel embedding in described solid glue groove.

Preferred as technique scheme, described led chip is electrically connected with described four connecting terminals by straight cutting electrode slice and plug-in electrode sheet; Described straight cutting electrode slice has a protuberance, and described plug-in electrode sheet is provided with the connecting portion suitable with this protuberance, and described protuberance is pegged graft interior to conduct with described connecting portion.

Preferred as technique scheme, described lamp housing is buckled in the described lamp socket.

The utility model proposes a kind of LED bulb, described LED bulb comprises: be provided with led chip and pcb board as light emitting source in the lamp housing, described pcb board passes through the silica gel embedding in described lamp housing; Described led chip is fixedly set on the described pcb board; Described pcb board bottom surface is provided with four connecting terminals that are arranged side by side.The LED bulb that the utility model proposes can be made the LED bulb efficiently, and LED bulb employing led chip is more stablized durable as light emitting source.And because employing four connecting terminals side by side, when connecting into the lamp string, it is convenient stable to peg graft.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.For the person of ordinary skill in the field, to the detailed description of the present utility model, above-mentioned and other purposes of the present utility model, feature and advantage will be apparent.

The utility model first preferred embodiment such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4 have proposed a kind of LED bulb, comprise lamp housing 8 and lamp socket 4, described lamp socket 4 and lamp housing 8 snappings; , be provided with led chip (not shown) in the described lamp housing 8 as light emitting source; Be provided with pcb board 6 in the described lamp housing 8, described pcb board 6 passes through the silica gel embedding in described lamp housing 8; Described led chip fixedly install with described pcb board 6 on; Described pcb board 6 bottom surfaces are provided with four connecting terminals 2 that are arranged side by side, and described led chip is electrically connected described four connecting terminals 2.

As shown in Figure 3, Figure 4, described pcb board 6 is provided with solid glue groove 7, and described led chip is fixed in the described solid glue groove 7, and passes through the transparent silica gel embedding in described solid glue groove 7.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, described led chip is electrically connected with described four connecting terminals 2 by straight cutting electrode slice 5 and plug-in electrode sheet 3; Described straight cutting electrode slice 5 has a protuberance, and described plug-in electrode sheet 3 is provided with the connecting portion suitable with this protuberance, and described protuberance is pegged graft interior to conduct with described connecting portion.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, described lamp housing 8 is buckled in the described lamp socket 4.

The utility model can be made by the following method

Step 1; The led chip that colors such as red, green, blue is different adopts the ultrasonic wave gold ball bonding to be welded on the pcb board 6, and protective resistance and straight cutting electrode slice 5 be welded on the pcb board 6, will consolidate glue groove 7 and be installed in and carry out transparent silica gel embedding protection led chip on the PCB wiring board 6;

Step 2, the light source block that PCB wiring board 6 and solid glue groove 7 are combined into are positioned in the lamp housing 8, and embedding silica gel forms LED polychrome bulb subsequently;

Step 3, LED polychrome bulb is installed on the lamp socket 4 that is connected with four connecting terminals 2, inserts admittances by straight cutting electrode slice 5 and plug-in electrode sheet 3;

Step 4 is specially: thus lamp housing 8 is by latch closure on it and the lamp socket 4 fixing one that form.
