Description
Technical field
The present invention relates to a kind of radiating shell of high-powered LED lamp.
Background technology
Along with popularizing of high-power LED lamp, the problems such as power supply reliability, applicability and heat radiation need comprehensive consideration to design more.The back of the radiating shell of high-power LED lamp common at present all can be arranged arranges radiating fin more, the front portion of radiating shell arranges mounting structure, be fixedly installed one or more LED chip installation base plate (single-ended lamp is a LED chip installation base plate normally, is positioned at positive Middle face in the front of this mounting structure; Double-ended lamp is two LED chip installation base plates normally, are positioned at front both wings), (for single-ended lamp, next-door neighbour's LED chip installation base plate usually, near the installation stiff end of light fixture to arrange a power storehouse in other positions depression in front; For double-ended lamp, be usually located at positive Middle face).
Radiating shell and mounting structure thereof adopt extrusion process shaping usually, according to current structure, when radiating shell size is done large by demand fulfillment significant power demand, after die casting completes, length direction especially produces obvious warpage, make troubles to follow-up shaping process, and percent defective also can increase, cost significantly increases thus.And if increase merely thickness, then the internal stress in press casting procedure is by proportional increase, and difficult forming, product weight obviously increases.
And such mounting structure makes the mounting arrangement of LED chip be restricted, the installing space leaving power storehouse for is very limited, and is unfavorable for cabling.And the power module of high-power LED lamp compares to LED chip and more easily breaks down, and current version is also unfavorable for the maintenance of power supply.
In addition, a lot of occasion proposes the demand of intelligent management to high-power illumination equipment (as street lamp etc.) in recent years, according to such mounting structure, the size of power storehouse cannot install more electronic module, usually a power supply can only be installed in power storehouse, have to other electronic module is separated with LED lamp body and fixes separately, carry out connection.
Summary of the invention
The present invention proposes the comprehensive radiating shell of a kind of high-powered LED lamp, and the radiating shell for large-size can ensure the smooth of mounting structure, also improves the intensity of radiating fin to a certain extent, possesses good radiating effect simultaneously.
Technical scheme of the present invention is as follows:
The comprehensive radiating shell of high-powered LED lamp, the back of radiating shell is arranged arranges radiating fin more, and radiating fin is vertical with the length direction of radiating shell, parallel with the width of radiating shell; The front portion of radiating shell is provided with plate mounting structure, is provided with many reinforcements (radiating fin nature is as the reinforcement on width) at the back side of whole mounting structure along its length; Be fixedly installed power storehouse and one or more LED chip installation base plate respectively at the back side of mounting structure and front, power storehouse and the projected position of LED chip installation base plate in this mounting structure stagger mutually; Accordingly, between many rows radiating fin at radiating shell back, reserve the installing space of power storehouse; Offer cable hole the bottom surface of power storehouse is through, the circuit on LED chip installation base plate introduces power storehouse through this cable hole.
On the basis of above scheme, the present invention has also done following optimization further:
In the power storehouse region at the mounting structure back side, also many reinforcements are set in the direction of the width, make power storehouse inner bottom surface form the protruding grid be made up of reinforcement.
The thermal vias of through described mounting structure is provided with in described protruding grid.
A thermal vias is provided with in each grid of described protruding grid.
Described power storehouse is rectangular structure, and the fringe region connected with the sidewall in power storehouse at described protruding grid arranges rectangular thermal vias, and wherein one or two rectangular thermal vias is simultaneously as described cable hole.
Described radiating fin exceeds the outward flange of radiating shell front end face in the direction of the width, arranges the rinforcement bar of bar shaped on the wing top of all radiating fins along the solidification of radiating shell length direction.
The rinforcement bar of described bar shaped has two, lays respectively at the both sides of integral heat sink fin.
The present invention has the following advantages:
1, the layout of LED chip (installation base plate) is more flexible.Because the front of mounting structure is smooth, LED chip (installation base plate) can be arranged in free zoning.
2, the versatility of LED lamp is good.Breadth and the height of power storehouse can promote, make it possible to hold the power supply (high power, middle low-power) installing two profiles number simultaneously, even can also add remotely controlled electronically module (physics addressing system) again, and be convenient for changing different lamp holders, thus meet industry requirement that is energy-conservation, low-carbon (LC).
3, profile is succinctly attractive in appearance, decreases wiring, and cabling is succinct.
4, be provided with many reinforcements along its length at the plate mounting structure back side, avoid the warping phenomenon in die cast process, the base thickness of mounting structure can be less, alleviates product weight.
5, in power storehouse, form the reinforcement of latticed projection and louvre is set, reduce the contact area of electronic module and radiating shell in power storehouse, the heat avoiding light emitting source to produce directly conducted to electronic module (easily the overheated electronic module that causes lost efficacy); Whole synthesis convection current, radiation and conduction three kinds of radiating modes; And LED chip installation base plate also can be installed in the front of the mounting structure corresponding to power storehouse region, be enough to mate radiating requirements, make in the layout of mounting structure front LED chip installation base plate more flexible.
