Description
Technical field
This utility model relates to LED, particularly relates to a kind of LED bulb with heat-conducting type light source board.
Background technology
Due to LED have that volume is little, power consumption is low, length in service life, high brightness, environmental protection and the advantage such as sturdy and durable, be widely used at lighting field.
Method when LED is applied to illumination is the light source board being fabricated to LED be made up of with the LED being arranged on substrate substrate, then drives light source board to carry out luminescence by power supply driver.Chinese Patent Application No. be 2024200350344, Publication No. CN203775877U, entitled " a kind of reflection-type LED illumination lamp " patent document in i.e. disclose a kind of existing LED.The lamp housing (i.e. bulb shell) of the bulb in this patent includes the lamp holder, plastic tube and the cell-shell that are connected in turn, is provided with light source board in cell-shell.This LED bulb is the lamppost by arranging glass structure in cell-shell, and lamppost and cell-shell surround sealing cavity, fills gas and dispel the heat in annular seal space body, and plastic tube is positioned at annular seal space external body, not makes full use of plastic tube.A kind of version of the substrate in existing light source board is that substrate uses PCB, includes insulation board and the Copper Foil being printed on substrate.The luminous plaque of this structure has the disadvantage that in installation process, the poor flatness at the position of substrate is supported due to lamp housing, so substrate is supported for some strong points with between lamp housing, thus causes heat that the LED on luminous plaque produces can not pass to shell through substrate well and lose thus cause radiating effect poor；Substrate is fixed with shell by bolt, bothers during installing/dismounting luminous plaque.
Utility model content
This utility model provides a kind of reflector can transfer heat to the LED bulb with heat-conducting type light source board of lamp housing well, solves the problem that heat can not be passed to lamp housing by luminous plaque in existing LED bulb well.
More than technical problem is that and solved by following technical proposal: a kind of LED bulb with heat-conducting type light source board, including lamp housing and the light source board being arranged in lamp housing, described light source board includes substrate and the LED being arranged on substrate, described lamp housing includes lamp holder and cell-shell, it is characterized in that, the edge of described substrate is fitted with conducting strip in the way of horizontal, and described lamp housing is provided with support rim, and described substrate is supported on described support rim by described conducting strip.This utility model is supported on the support rim of lamp housing by conducting strip and links together with shell.Owing to conducting strip is fitted on substrate in the way of horizontal, so the heat that power supply driver produces can pass to conducting strip well, although now conducting strip with the way of contact between the support rim of lamp housing compared with as, but due to the good heat conduction effect of conducting strip, it is possible to raising heat passes to the effect of lamp housing thus plays the effect improving radiating effect.
As preferably, described support rim is provided with card contact pin, and the edge of described substrate is provided with connection breach, and described substrate is fixed together in being connected to described connection breach by described card contact pin with described lamp housing.During use, it is connected in card contact pin realize reflector fixing with lamp housing by connecting breach, convenient time fixing.
As preferably, described connection breach has two, and described card contact pin has two panels, and said two connects breach and is symmetrically distributed in the both sides of substrate, and described two panels card contact pin is connected to said two correspondingly and connects in breach.Can be further by stationarity when fixed effect and connection.
As preferably, described conducting strip and described connection breach separated.It is prevented from repeatedly installing/dismounting luminous plaque and causes heat-conducting plate to produce the phenomenon tilted so that repeatedly after installing/dismounting, conducting strip is still able to same substrate and is reliably connected together.
As preferably, described conducting strip has two pieces, and described connection breach is between described two pieces of conducting strips.Structural compactness is good.
As preferably, described conducting strip is list structure.When being laid out conveniently.
As preferably, described substrate is circular, and described conducting strip is list structure, and described conducting strip is circumferentially extending along substrate.Can be conveniently mounted in globular bulb.
This utility model also includes connecting tube and heat sink, described connecting tube includes being molded outer tube and being positioned at the metal inner pipe of injection outer tube, described injection outer tube and metal inner pipe are Split type structures, described heat sink links together with described metal inner pipe, described substrate horizontal is on described heat sink, it is provided with support level in described injection outer tube, described metal inner pipe is provided with in-flanges, described in-flanges is connected on described support level by screw, and described lamp holder is linked together with described cell-shell by described connecting tube.During use, produced by light source board, heat passes to metal inner pipe also by heat sink and loses.Arranging metal inner pipe in injection outer tube and constitute connecting tube, light source board is also attached to heat sink, heat sink is connected with metal inner pipe, thus plays the effect improving radiating effect.This version structural strength of connecting tube is good, also also serves as radiator use, so that plastic tube is fully used.Injection outer tube is Split type structure with metal inner pipe, easy to make.Thus solve that the existing LED bulb radiating effect being provided with plastic tube is poor, plastic tube utilizes insufficient problem.
When this utility model has an advantage that use, heat can pass to shell well, therefore good heat dissipation effect.
