Description

LED

Technical field

It the utility model is related to lighting field, more particularly to LED.

Background technology

At present, with the development of science and technology, LED light source is considered as forth generation lighting source, LED bar graph lamp relies on luminous efficiency High and low power consumption, it is safe the advantages that, be widely used in various lighting fields.

LED is typically made up of lamp housing, light source board, lampshade three, at present light source board typically using bonding by the way of and lamp Shell is fixed, and it easily comes off after being hit（As accidentally fallen to ground）, unstable product quality.

Utility model content

The purpose of this utility model is to provide a kind of LED, and light source board is difficult for drop-off with lamp housing, Improving The Quality of Products.

Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of LED, including lamp Shell, the light source board being fixed on lamp housing, the lampshade for being located on lamp housing light source board one end, the envelope inner wall are provided with the One banking stop and the second banking stop, the first banking stop and the second banking stop are arranged at intervals, and opening up one on second banking stop opens Mouthful, a limiting section for being less than or equal to the openings of sizes is fixed on the side of the light source board, the limiting section of the light source board is certainly After opening enters rotation, limiting section abuts the first banking stop and the second banking stop respectively.

By way of rotary clamping so that from opening, the limiting section into after rotating abuts the first banking stop to limiting section respectively With the second banking stop, light source board is not easy to drop due to the limitation of the first banking stop and the second banking stop；Eliminate viscose glue simultaneously Use, cost is lower.Here banking stop not merely refers to sheet, can be bulk etc., as long as playing position-limiting action .

Further, neck is offered on the light source board, the envelope inner wall sets the fastener coordinated with neck.

Neck and fastener and set and make it that light source board is not susceptible to circumferentially rotate, further lift light source board and lamp housing Connection reliability.

Further, open up a guiding breach on the light source board side, the guiding breach be located at neck side and with Neck connects.

The setting for being oriented to breach facilitates fastener to be caught in neck.

Further, the light source board includes insulation board and the lamp bead being arranged on insulation board, the insulation board and lamp Shell connects.

Further, the insulation board is bakelite plate or glass-fiber-plate.

Original aluminium base is substituted by insulation board, while insulation board is directly connected with lamp housing, heat caused by lamp bead Directly shed by insulation board, lamp housing, better heat-radiation effect；And original internal layer aluminium lamination and outer layer heat resistant plastice layer group is abandoned Into lamp housing structure, cost is lower.

Further, the insulation board and lamp housing clamping or bonding.

Further, a link slot, the lampshade and link slot clamping are opened up in the lamp housing.

Further, in addition to it is used for the mounting assembly for installing the LED, the mounting assembly is included on the outside of insertion lamp housing Metal connecting sheet, the nut piece on the inside of insertion lamp housing, through metal connecting sheet and lamp housing and the spiral shell that is threadedly coupled with nut piece Bolt.

Metal connecting sheet intensity is high, and by the connected mode of metal connecting sheet and nut piece, by suffered by metal connecting sheet Power is dispersed to outside in lamp housing, is hardly damaged.

In summary, the utility model has the advantages that：1）By the connected mode of light source board and lamp housing from bonding Make rotary clamping into, lift the connection reliability of light source board and lamp housing, improve the quality of LED；2) substituted by insulation board Original aluminium base, while insulation board is directly connected with lamp housing, heat caused by lamp bead is directly dissipated by insulation board, lamp housing Go out, better heat-radiation effect；And the lamp housing structure of original internal layer aluminium lamination and outer layer heat resistant plastice layer composition has been abandoned, cost is more It is low.
