Background technology
Because long service life, the energy consumption of LED are low, energy savings is remarkable, high-power, oneself is widely used in the daily life high-brightness LED as light source, as the great power LED module, its luminous efficiency height, good energy-conserving effect are used for the city illumination decorative engineering more and more.Traditional great power LED die set mainly comprises LED and aluminium base, LED directly welds and is fixed on the aluminium base, the parts of traditional this great power LED die set all are exposed fully aerial, can not waterproof, and be corroded easily or damage.In order to overcome this problem, there is the inventor to propose a kind of great power LED die set that possesses waterproof ability, the described great power LED die set that possesses waterproof ability is that CN200820050708.8 is disclosed, the disclosed this great power LED die set of CN200820050708.8, comprise the led circuit plate, the heat-radiating aluminum plate, base, the upper cover plate that is tightly connected with base, the led circuit plate connects firmly and is connected on the heat-radiating aluminum plate, offer disposal area on the base with heat-radiating aluminum plate coupling, the heat-radiating aluminum plate is placed in the disposal area of base, the top of upper cover plate offer with the led circuit plate on the through hole that is complementary of LED, LED places through hole, and protrudes from the end face on the top of upper cover plate.After the problem that the disclosed this great power LED die set of CN200820050708.8 exists is that the heat-radiating aluminum plate as the supporting device of led circuit plate and radiating piece is placed in the base of sealing, heat-sinking capability greatly reduces, another problem that exists is that the LED on the led circuit plate still exposes in air, of long duration still have steam from the slit of LED and upper cover plate, to infiltrate, the exposed simultaneously easy dust stratification of aerial LED, influence luminous, moreover, lighting angle is also less, and prior art has further improved necessity for this reason.
Summary of the invention
The purpose of this utility model is to provide a kind of great power LED die set, to overcome the problem that prior art exists.
A kind of great power LED die set of the present utility model, comprise LED, aluminium base, power line, heat dissipation base, double faced adhesive tape, described LED is welded on the aluminium base, described power line connects firmly and is connected on the aluminium base, it is characterized in that also comprising transparent cover, described aluminium base is installed in the described transparent cover, the corresponding position of described transparent cover LED inboard and on the aluminium base is provided with the secondary light-distribution concave mirror, described aluminium base is positioned on the heat dissipation base, described transparent cover connects firmly by screw and heat dissipation base and connects, being in contact with one another of described transparent cover and heat dissipation base is filled with fluid sealant between face, described double faced adhesive tape sticks on the lower plane of described heat dissipation base.
This great power LED die set of the present utility model has solved waterproof and the bad problem of heat dispersion by transparent cover, aluminium base are set with the cooperation between heat dissipation base; Solved the lighting angle problem of smaller that prior art exists by the mode that on the position corresponding, transparent cover inboard, is provided with the secondary light-distribution concave mirror with LED; Then further promoted the water resistance of product by filling with sealant, obviously the purpose of this utility model is achieved.
As further improvement, described power line has two groups, one group is power input line, another group is power supply output line, connect one to one between described power input line and power supply output line, power line is arranged to two groups, helps the cascade of great power LED die set of the present utility model, made things convenient for application.
As further improving, described transparent cover has the stage portion of a qualification aluminium base axial location, and described stage portion is pressed on the described aluminium base, thereby defines the axial location of aluminium base, make aluminium base better to connect firmly and connect, help improving heat dispersion like this with heat dissipation base.
