Description
Technical field
The utility model relates to a kind of Tunnel Lamp, particularly relates to a kind of helical teeth dust-proof radiating LED tunnel lamp.
Background technology
LED have power consumption less, applicability is strong, the response time is short, environmentally safe, the advantage such as multicolor luminous, obtain applying more and more widely in road lighting field, current highway or city tunnel, Under-cross tunnel, the wall ramp in both sides, tunnel that light fixture has is installed.Owing to having vehicle exhaust, greasy dirt and a large amount of dusts in tunnel, cause Tunnel Lamp light fixture fin surface to produce a large amount of dust accretions, have a strong impact on the heat radiation of LED tunnel lamp tool, thus affect the Performance and quality of LED tunnel lamp.Therefore, need to be improved LED tunnel lamp structure of the prior art, solve the problem of dust bulk deposition on fin, ensure LED tunnel lamp Performance and quality.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of helical teeth dust-proof radiating LED tunnel lamp, can solve the problem of dust bulk deposition on fin, ensures LED tunnel lamp Performance and quality.
A kind of helical teeth dust-proof radiating LED tunnel lamp of the present utility model, comprises the shell for mounted LED lamp bulb and lens; Described shell rear surface is provided with fin; Described fin is obliquely installed relative to the installed surface for mounted LED lamp bulb on shell;
Further, described fin is plain film or to the bending arc-like sheet of its incline direction;
Further, described fin and shell are a for the acute angle folded by between the installed surface of mounted LED lamp bulb, 10 °≤a≤80 °;
Further, a < 60 °;
Further, a=30 °;
Further, described fin surface is rippled surface.
The beneficial effects of the utility model are: a kind of helical teeth dust-proof radiating LED tunnel lamp of the present utility model, adopt the fin of inclined-plane heat radiation dentation, fin and ground is made to have certain oblique angle, dust is due to the reason of deadweight, cannot pile up in groove on a heat sink or between fin, avoid the heat radiation affecting LED tunnel lamp, ensure LED tunnel lamp Performance and quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, as shown in the figure: a kind of helical teeth dust-proof radiating LED tunnel lamp of the present embodiment, comprises the shell 1 for mounted LED lamp bulb 4 and lens 5, described shell 1 back side is provided with fin 2, described fin 2 is obliquely installed relative to the installed surface 3 for mounted LED lamp bulb on shell 1, one side of shell 1 is the installed surface 3 for mounted LED lamp bulb and lens, the back side of shell 1 refers to a side contrary with this installed surface 3, fin 2 is multiple and linearly arranges, flow in fin 2 groove to be beneficial to air, improve heat dispersion, the groove between fin 2 is made to move towards along tunnel to arrange when LED tunnel lamp is installed, down by fin 2 incline direction simultaneously, fin 2 and ground is made to have certain oblique angle, dust is due to the reason of deadweight, cannot pile up in groove on fin 2 or between fin 2, avoid the heat radiation affecting LED tunnel lamp, ensure LED tunnel lamp Performance and quality.
In the present embodiment, the arc-like sheet that described fin 2 is plain film or bends to its incline direction, fin 2 is one-body molded with shell 1, adopts plain film or arc-like sheet structure to be convenient to machine-shaping.
In the present embodiment, described fin 2 and shell 1 are a for the acute angle folded by between the installed surface 3 of mounted LED lamp bulb, and 10 °≤a≤80 °, the machine-shaping being beneficial to fin 2 enables dust landing under self gravitation effect simultaneously.
In the present embodiment, a < 60 °, makes the effective landing of dust, avoids causing dust bulk deposition.
In the present embodiment, a=30 °, angle design is reasonable, can not only make the effective landing of dust, and fin 2 width is comparatively large, and area of dissipation is large, perfect heat-dissipating.
In the present embodiment, described fin 2 surface is rippled surface, and rippled surface section is sinusoidal, considerably increases fin 2 surface area, can improve shell 1 thermal diffusivity, is beneficial to and extends LED tunnel lamp service life.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
