Description

A kind of photoelectric integral LED bulb

Technical field

The utility model relates to lighting technical field more particularly to a kind of photoelectric integral LED bulbs.

Background technique

LED illumination can be widely used in all kinds of fields, including indoor and outdoor lighting, architectural lighting, automotive lighting, road Lamp and portable lighting etc., as the LED bulb of substitution conventional incandescent, the independent driving electricity for the LED lamp that generally follows conventional lines Road adds the combination of LED light source substrate, i.e., the LED bulb of existing production, circuit connecting mode is mainly drive circuit die set Input terminal draws two conducting wires and connect conducting with the Live line Zero line terminals of lamp cap respectively, and the output end of drive circuit die set is drawn Two conducting wires are connected with the positive and negative anodes soldering terminals on light source substrate, and drive circuit die set is put using independent circuit board as carrier It being placed between lamp cap and light source substrate, this production method one is cumbersome to make, and need lead and light source substrate wiring to weld, two Carry out such LED bulb when in use, the independent circuit board of drive circuit die set is located at the narrow sky above lamp cap inner light source substrate Between, the natural diverging of the heat distributed by light source substrate from the bottom to top so that the circuit board of drive circuit die set it is easily heated from And service life is influenced, the circuit board of the drive circuit die set as LED bulb core component directly affects entire LED bulb Quality.

Summary of the invention

The purpose of this utility model is to provide a kind of photoelectric integral LED bulb, have simple for production, effectively improves simultaneously Bulb service life.

The technical scheme adopted by the utility model is a kind of photoelectric integral LED bulb, including lamp cap, it connect with lamp cap Outside bulb shell, the substrate that is installed on lamp cap, the substrate is divided into the firstth area and the secondth area, and firstth area is located at the week of substrate Border region is simultaneously inlaid with LED lamp bead, and secondth area is located at the intermediate region that the LED lamp bead on substrate surrounds, and welds useful In the driving circuit of driving LED lamp bead, the driving circuit is electrically connected with lamp cap by conducting wire, firstth area and the secondth area it Between be provided with several arc-shaped slots.

Wherein, the driving circuit uses constant current mode driving circuit.

Wherein, the first area back side of the substrate is glued with aluminium radiating board.

Wherein, the substrate is aluminium silicon carbide substrate.

Compared with the prior art, the utility model has the following advantages: a kind of photoelectric integral LED bulb of the utility model, The drive circuit board used when for traditional fabrication LED bulb is separated with light source substrate, and the number of terminals of wiring is more, circuit The mode that is linked and packed is complicated, the defect of high labor cost, by the way of drive circuit board and light source substrate one, can save people Work welding, production is easier, saves the self-powered circuit plate of conventional LED light bulb, saves lamp body space, keeps LED light brewed Make it is more flexible changeable, improve drive circuit works environment, improve the service life of entire lamp body.

Detailed description of the invention

Fig. 2 is the schematic diagram of substrate structure of the utility model.

Figure label show 1- lamp cap, 2- outside bulb shell, 3- substrate, the firstth area 4-, the secondth area 5-, 6- driving circuit, 7- Aluminium radiating board.

Specific embodiment:

For the understanding for deepening the utility model, the utility model is made below in conjunction with case study on implementation and attached drawing further detailed It states.The utility model can be implemented in the following way:

Referring to a kind of photoelectric integral LED bulb shown in Fig. 1 and 2, including lamp cap 1, the outside bulb shell being connect with lamp cap 12, The substrate 3 being installed on lamp cap 1, outside bulb shell 2 close the work for playing protective substrate 3 and light modulation on the substrate 3 as translucent cover cover With.The substrate 3 divides for the first area 4 and the second area 5, and firstth area 4 is located at the neighboring area of substrate 3 and is inlaid with LED light Pearl, secondth area 5 is located at the intermediate region that the LED lamp bead on substrate 3 surrounds, and is welded with the drive for driving LED lamp bead Dynamic circuit 6, the driving circuit 6 are electrically connected by conducting wire with lamp cap 1, are provided between firstth area 4 and the second area 5 several Arc-shaped slot realizes the optoelectronic integration of light-emitting component and driving circuit 6.

In addition and light using a kind of photoelectric integral LED bulb of the utility model, 6 plate of driving circuit does not have to when production 3 wiring of source substrate welding, assembly is simple, saves cost of manufacture, overall space is compressible, keeps configuration design more flexible, while lamp For tool in use, driving circuit 6 is located at the position of LED lamp bead plane, the heat from bottom to top distributed from LED will not gather drive On dynamic circuit 6, horizontal direction uses the first area 4 and the second area 5 in a manner of arc-shaped slot partition, further separates from light source Substrate 3 is conducted through the heat come, guarantees the service life of driving circuit 6.

Wherein, the driving circuit 6 of the utility model uses constant current mode driving circuit, avoids driving current beyond maximum rated Value promotes reliability, it is ensured that LED reaches expected brightness requirement, prolongs the service life.

Wherein, 4 back side of the firstth area of the substrate 3 of the utility model is glued with aluminium radiating board 7, can effectively accelerate to dissipate Heat extends lamp body service life.

Wherein, the substrate 3 of the utility model can also be made of aluminium silicon carbide substrate 3, sufficiently combine carbonization The different advantages of silicon ceramics and metallic aluminium, the thermal expansion coefficient to match with high-termal conductivity, with chip, density are small, light-weight, And high rigidity and high-flexural strength, heat conduction and heat radiation performance is splendid, the thermal expansion properties of lamp bead and 6 element of driving circuit are matched, Significant increase service life.
