Description
Technical field
The present invention relates to a kind of LED illuminating lamp, especially a kind of high-power LED illuminating lamp with self heat dissipation function belongs to LED lighting engineering class
Background technology
Because the LED lighting has the factory director in service life, start-up time is short, energy-saving effect is remarkable, do not have ultra-violet radiation and advantages such as environmental pollution, safety in utilization height, is approved widely, has become the main flow of following energy-saving lamp.
But, because the LED lamp is photoelectric device, in its photoelectric conversion process, have only 15～25% electric energy to convert luminous energy to, remaining electric energy nearly all converts heat energy to, and the temperature of LED light fixture is raise.The existence of this phenomenon just if fansink designs is bad, can cause the heat of LED lamp light source to loose not, causes the light efficiency decline of light fixture and even burning of whole light fixture.The design of the radiator structure of present high-power LED lamp is to design metal heat sink very big and expose the radiating effect to obtain to match with the led light source heat in air, though this radiator can play the thermolysis of led light source, and the bulkiness of radiator and exposed; Cause the outward appearance of LED indecency; Volume is heavy, and cost increases, more because the LED light fixture connects high voltage source; Metal heat sink is exposed outside, and end user's life security has been constituted very big threat.Low-power LED lamp in order to solve the heat dissipation problem of LED light electrical part, is arranged on bulb external power joint bottom extending part with radiator usually.The radiator structure of this relative closure type shows that in actual use it can't reach fast, the purpose of temperature with high efficiency.
Therefore, seek the radiator structure that is applicable to LED, improve the LED light fixture from heat radiation function, be that the LED lamp is generalized to the problem that must solve in the civil area more widely all the time.
Summary of the invention
The object of the invention: be intended to propose a kind of high-power LED illuminating lamp, hope further to improve the radiating effect of high-powered LED lamp through simpler structure with self heat dissipation function.
The foregoing invention purpose realizes through following technical scheme:
This high-power LED illuminating lamp with self heat dissipation function; Comprise lamp holder, LED photophore, drive circuit assembly, radiator and the cell-shell of being with steam vent; It is characterized in that: described radiator is a hollow tube-shape body; Described LED photophore is the ring-type photophore that is made up of annular support and led chip, and described cell-shell is the annular solid of a central ventilation road, the asymmetric upper shed of Internal and external cycle housing for the centre; Said radiator is suspended at the lamp holder lower central through a fixed head; Its underpart is connected with the inner ring housing of fixing, be connected the cell-shell on the fixed head equally, constitutes the integrated self-heat irradiation device from bottom to top that is made up of the steam vent that is provided with on cell-shell central ventilation road, radiator hollow channel and the lamp holder outer wall thus; Described ring-type photophore is in the radiator bottom, and through the steam vent that is provided with on axial ventilation road in top and the radiator that lamp holder is connected and the lamp holder outer wall constitute from bottom to top, from the inside to the outside integrated self-cooling LED illuminating lamp.
Described annular photophore is made up of ring support and the led chip that is arranged in the ring support.
Described led chip is placed in the annular groove of ring-type photophore.

The specific embodiment
This high-power LED illuminating lamp with self heat dissipation function as shown in the figure, it is a kind of inventive improvements to the high-power LED illuminating lamp of existing self heat dissipation function.It comprises lamp holder, LED photophore, drive circuit assembly, radiator and the cell-shell of being with steam vent, and this inventive improvements is embodied in three aspects:
One of which; Fansink designs is become the fin structure of hollow and annular, and the heat radiation contact-making surface that not only utilizes fin structure to increase radiator reaches heat radiation, with again fansink designs being become the hollow tube-shape body; This has set up an inner core radiating surface for radiator in fact again, and this can accelerate radiating effect undoubtedly;
Its two, the conventional collar plate shape support that led chip is installed is designed to hollow circular ring shape support, make the led chip that is placed on the hollow circular ring shape support, become the radiator structure of two-dimensional space by a radiator structure that utilizes conventional collar plate shape support;
They are three years old; To be nested with by the ring-type photophore that annular support and led chip constitute after the radiator bottom; In conjunction with cell-shell is the annular solid of middle opening; Make the steam vent that is provided with on axial ventilation road and the lamp holder outer wall in the radiator and the annular solid in the middle of the cell-shell, constitute from bottom to top, from the inside to the outside integrated from radiator structure.
Described radiator is a hollow tube-shape body, and described LED photophore is the ring-type photophore that is made up of annular support and led chip, and described cell-shell is the annular solid of a central ventilation road, the asymmetric upper shed of Internal and external cycle housing for the centre;
This high-power LED illuminating lamp of forming by lamp holder, LED photophore, drive circuit assembly, radiator and cell-shell etc. with self heat dissipation function; Its concrete structure is: said radiator 5 is suspended at lamp holder 1 lower central through a fixed head 2; Its underpart is connected with the inner ring housing of cell-shell 3 on fixing, be connected fixed head 2 equally, constitutes the integrated self-heat irradiation device from bottom to top that is made up of the steam vent that is provided with on cell-shell central ventilation road, radiator 5 hollow channels and lamp holder 1 outer wall thus; Described ring-type photophore 4 is located at the radiator bottom, and through the steam vent that is provided with on axial ventilation road in top and the radiator 5 that lamp holder 1 is connected and the lamp holder outer wall constitute from bottom to top, from the inside to the outside integrated self-cooling LED illuminating lamp.
Described annular photophore 4 is made up of ring support and the led chip 7 that is arranged in the ring support.
Described led chip is placed in the annular groove of ring-type photophore.
The barrel outer surface of described radiator is provided with radiating fin.
In technique scheme; Important function has been played in improvement to the led chip supporting structure, and it has broken in the traditional design general the heat sink of integrated high power LED conventional bracket is the mentality of designing of a disc, porose anchor ring in the middle of the disk of single plane shape is changed into; Both made led chip constitute a contact-making surface through last plane with ring support; Through the contact-making surface heat radiation of radiator bottom, simultaneously, heat radiation is realized at inboard through the ring support again socket interface with radiator.The results showed that the punching support after this improvement has the following advantages:
A, increase cooling surface area can reach heat radiation better faster, under equal-wattage, identical radiator condition, adopt the annular support after improving can make surface temperature descend 7%.This is very effective to prolonging product service life, improving reliability;
B, the contrast through two groups of white light products find that both luminous fluxes are very approaching;
C, can reduce the area that fluorescent material spreads out, improve the product hot spot;
D, can save backbone metal cost, plated material and encapsulation silica gel cost, guarantee that the overall product cost descends.
Adopt that technique scheme constituted by bulb shell in ventilating duct and the lower annular in the middle of top lamp holder steam vent, the middle part radiator constitute jointly from bottom to top, from the inside to the outside integrated from radiator structure; Have extremely strong ventilation and heat effect, quick, the high efficiency and heat radiation that require when this works for led chip are very good.
