Description

The LED lamp

Technical field

The utility model belongs to the illuminating equipment technical field, is specifically related to a kind of LED lamp

Background technology

since strong point such as the LED light fixture has that light efficiency is high, energy-conservation, long service life, environmental protection and maintenance workload are little and extremely people think highly of; In disclosed Chinese patent document, is no lack of technical information about the LED light fixture; Slightly with give an example like CN201748219U (a kind of many LED light fixtures of use), CN201757302U (assembly type LED lamp), CN201772302U (LED light fixture), CN101984280A (LED light fixture), CN201462616U (a kind of LED pendent lamp), CN201731397U (inhale to push up and hang fitting structure), CN201568846U (the energy-conservation factory building pendent lamp of LED), CN201187717Y (LED electrolier lamp) and CN201819125U (active heat removal LED pendent lamp), or the like.

such as industry knowledge, the LED lamp time can produce heat in work, if can not heat spread to the external world; So not only can influence service life; And the problem of light decay and so on can appear, therefore, the heat radiation of LED lamp receives people's attention all the time.

are no lack of the technical information about the LED heat radiation equally in the Chinese patent document; " the LED lamp " typically recommended like publication number CN1755192A; This patent application scheme is through the transparent or semitransparent astigmatism plate of setting up and that this astigmatism plate is combined with led light source is as a whole; Use the shell of major diameter (patent is claimed large tracts of land) metal cup simultaneously, thereby improve radiating effect (specifically can referring to 3 page of the 2nd row of Instructions Page 2 last column to the of this patent application) as lamp.The shortcoming that this patent application scheme exists is: one of which, radiating effect can not show the degree alleged like its specification, because the heating part of LED lamp has two, and the one, pcb board (seal carving circuit board), the 2nd, led light source.Can know from the structure of this patent application; Because pcb board combines with insulating barrier; More properly say with the crown top of burner to combine, so the radiating effect of pcb board is difficult to embody, and the heat dispersion of LED also is difficult to embody; Because the heat that LED produces is enclosed in the cavity volume of metalized lamp cup by light cover, be difficult to spread to the external world with thermaltransmission mode apace by metalized lamp cup; Its two, have the deficiency attend to one thing and lose sight of another, this diameter that is through increasing metalized lamp cup of so-called Gu can improve radiating effect to a certain extent, and so-called mistake that be and increase bulkyization that metalized lamp cup can make the LED lamp simultaneously; Its three, the integral heat sink area is little and radiating mode is stiff (dullness), for example the outer wall of insulating barrier does not smoothly have convex-concave, and is unfavorable to dispelling the heat; Its four, the heat that led light source produces can exert an influence to pcb board, because lack the effective isolation measure between the two.

again; " LED lamp " that publication number CN101082411A provides improves radiating effect through semiconductor refrigerating agent and radiator fan; But so structure can significantly increase complexity and the manufacturing cost of LED; And semiconductor chilling plate and radiator fan only have the effect of forced heat radiation to pcb board (patent is claimed controller), and the diffusion of the heat that produces for LED (patent is claimed lamp body) is lost biased.

reach, and " the active heat removal LED pendent lamp " that Granted publication CN201819125U introduces has achievement for the heat radiation of led light source (patent is claimed the LED module), but loses biased equally for the heat radiation of pcb board (patent is claimed control circuit).

In view of above-mentioned prior art, be necessary to improve, the applicant has done useful design for this reason, and the technical scheme that will introduce below produces under this background
