Description
Technical field
The utility model relates to a kind of luminous intensity distribution and the good LED lamp that dispels the heat.
Background technology
LED is also known as light emitting diode, be a kind of can be the semiconductor of luminous energy by electric energy conversion, it changes the luminous principle with the luminescence of electricity-saving lamp tricolor powder of incandescent lamp tungsten filament, adopts electroluminescence, clearly, the life-span is long, light efficiency is high, radiationless and low energy consumption for the feature of LED.
At present, the most common in prior art is adopt multiple low power LED to carry out arrangement illumination, this lamp body structure does not have the requirement of luminous intensity distribution performance, it configures an independent little reflector by a LEDs and forms a light emitting source, and usually whole car light needs 12 ~ 30 such low-power LEDs to combine.This technique is simple, technology is original, and moulding is dull, and luminous intensity is low, and its advantage is that manufacturing cost is lower, not advisability.
Separately have and adopt a kind of great power LED of cartridge type as headlamp light source, this lamp body carries out secondary reflecting by the reflector of vacuum coating, just as the LED flashlight that we are common, the light source irradiated out is a cylindrical shape, luminous intensity can reach 4000cd, but it is also careless about luminous intensity distribution performance, do not reach the safe handling requirement of motor vehicle.
Market also has one be adopt great power LED as light source, and scioptics carry out secondary light-distribution.This structure can reflect a part of luminous intensity distribution feature, but still does not reach the light distribution requirements of motor vehicle, and dipped beam can not present a "cut-off"line clearly.
Utility model content
For solving the problem, the utility model proposes a kind of simple and reasonable, the luminous intensity distribution that cyclicity is good and the good LED lamp that dispels the heat.
Luminous intensity distribution of the present utility model and the good LED lamp that dispels the heat, comprise lamp door wall, cavity, cooling body, LED lamp, curved reflector, lamp door substrate, heat pipe, cooling chamber and LED lamp circuit board, the lamp door that described lamp door wall and lamp door substrate are formed, described lamp door wall is provided with cavity, described lamp door wall is provided with LED lamp circuit board, described LED lamp circuit board is provided with LED lamp, described lamp door substrate is provided with curved reflector, the lamp door wall of described both sides is connected and is provided with transparent lamp shade, thermal trough is provided with below described LED lamp circuit board, described thermal trough inside is provided with heat pipe, described LED lamp is connected with cooling body by heat pipe, described cooling body is positioned at the cooling chamber of lamp door wall and curved reflector formation.
