Description
Technical field
This utility model relates to a kind of durable type LED street lamp.
Background technology
At present, owing to LED light source has the advantage such as energy-saving and environmental protection, longevity, therefore it is widely used in outdoor illumination field, especially for the street lamp that electric consumption on lighting proportion is bigger.
The LED of all LED street lamp welds on the substrate (such as aluminium base) of metal material mostly in the market.The sinking path of whole LED street lamp: outside LED → pcb board (aluminium base) → thermal conductive insulation glue → metal shell → lamp body, although the metal basal boards such as aluminium base have the electrical insulation properties of extremely excellent heat conductivility and high intensity, but sinking path is oversize, the heat that LED produces not easily is got rid of, cause LED junction temperature rise, the rising of LED junction temperature can make the current amplification factor of transistor increase sharply, cause that collector current increases, make again junction temperature raise further, ultimately result in LED failure.Work it addition, LED street lamp is chronically under high temperature, the bad phenomenon such as the insulating properties of street lamp can be caused to degenerate, the heat ageing of component damage, material, low melting point weld cracking, solder joint come off.
Radiating treatment has become as one of vital challenge in LED street lamp design, namely tighten at framework, when working place is increasingly less, how to solve the heat radiation of LED, the heat that PN junction produces is made to distribute as soon as possible, not only can improve the luminous efficiency of product, also improve reliability and the life-span of product simultaneously.In view of LED is higher to the requirement of radiating condition, the limit value if PN junction junction temperature is above standard, LED will aggravate light decay, lowers efficiency, and even quits work.So, heat dissipation problem is the most scabrous key of LED street lamp.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of durable type LED street lamp, this device is in use, rainwater and wind can be circulated by radiating groove, the heat in metal heat sink can be taken away, avoid the accumulation of heat, metal heat sink in this device is dismountable structure simultaneously, it is simple to later maintenance and replacing, reduces the use cost of LED street lamp.
For solving the problems referred to above, this utility model adopts the following technical scheme that
A kind of durable type LED street lamp, including lamp housing, described lamp housing while be provided with installation pipe, driving power supply it is provided with in lamp housing, the medium position place of described lamp housing is provided with groove, it is provided with metal heat sink in described groove, it is combined with screw between described metal heat sink and described lamp housing, it is provided with aluminium base before described metal heat sink, described aluminium base is provided with several LED chips, the plate face of described aluminium base is provided with line layer, the plate face of described aluminium base is provided with several grooves, described LED chip is arranged in a groove, described aluminium base is provided with the LED chip solder joint electrically connected with line layer in the both sides of each groove, it is connected to wire between LED chip solder joint and described LED chip, the lens covering described aluminium base it are provided with before described metal heat sink, described aluminium base is symmetrically arranged with four pieces, it is provided with radiating groove between two adjacent described aluminium bases.
As preferred technical scheme, described groove is circular groove.
As preferred technical scheme, being provided with radiating groove in described metal heat sink, be provided with aluminium base radiating fin in described radiating groove, described metal heat sink is also aluminium base.
The beneficial effects of the utility model are: this device is in use, rainwater and wind can be circulated by radiating groove, the heat in metal heat sink can be taken away, avoiding the accumulation of heat, the metal heat sink in this device is dismountable structure simultaneously, it is simple to later maintenance and replacing, reduce the use cost of LED street lamp, the structure of this device is relatively simple, and cost is comparatively cheap, is suitable for promoting the use of.
