The utility model has two electric light sources with different lighting brightness, and can be automatically switched to suit the different needs of the day and night in the tunnel.
Description
Technical field
The utility model relates to a kind of tunnel illumination light fixture, relates in particular to a kind of pair of light source tunnel illuminating lamp.
Background technology
At present, special-purpose tunnel illuminating lamp generally is to adopt the single light source structure, promptly is made of radiating shell, diffuser and corresponding single light source.Chinese patent CN2804575Y discloses a kind of tunnel illuminating lamp, comprises the light-emitting device of radiating shell, diffuser and employing LED.The light-emitting device encapsulation that to adopt LED that diffuser and radiating shell are suitable.The light fixture that adopts this structure is exactly a kind of single light source tunnel illuminating lamp, and this illuminating lamp can provide the illumination of single power for the tunnel.But in the tunnel, the lighting demand of day and night is different, daytime tunnel illumination brightness requirement height, night tunnel illumination brightness needs low.Therefore the tunnel illuminating lamp incompatibility daytime of single light source and night highway tunnel illumination needs.
The utility model content
The utility model aims to provide a kind of electric light source with two kinds of different luminosity, can carry out switch operating automatically, adapt to daytime and night tunnel illumination two light source tunnel illuminating lamps of different needs.
The technical scheme that the utility model adopted is: a kind of pair of light source tunnel illuminating lamp, comprise radiating shell, diffuser and light-emitting device, light-emitting device is installed in the radiating shell, radiating shell simultaneously is equipped with diffuser, control circuit when it is characterized in that also comprising, described light-emitting device is at least two groups, and the light-emitting device input is connected with the time control circuit output end, and the time control circuit output end passes radiating shell and is connected with power supply.
Described light-emitting device comprises LED, printed circuit board (PCB), constant-current source, connecting line, two LED are installed on the printed circuit board (PCB) at least, described printed circuit board (PCB) is an aluminium base, printed circuit board (PCB) is mounted on the interior installed surface of radiating shell, constant-current source is installed in the radiating shell, the control circuit when input of constant-current source connects, output connect the input of printed circuit board (PCB) by connecting line, and printed circuit board (PCB) is mounted in the radiating shell.
The described radiating shell back side is provided with radiating fin, and the radiating shell both sides are provided with baffle plate, and baffle plate is provided with louvre.Be provided with sealing joint strip between described diffuser and the radiating shell.
The beneficial effects of the utility model are: (1) by the time control circuit light-emitting device of different capacity can be switched automatically, substituting on night and daytime respectively provides illumination, has satisfied actual demand; (2) two groups of light-emitting devices take turns to operate, and the reason stream time is long and wear out to make light-emitting device, has improved the service life of light fixture; (3) because the road plate that LED is installed directly is mounted on the radiating shell, and the back side of radiating shell is covered with radiating fin, and two baffle plates in side are equipped with louvre, therefore, the heat that LED work produces can very fast dispersing, the service life of having improved light fixture; (4) adopt adhesive tape sealing, diffuser reliably is connected with radiating shell, also improved the shell protection grade simultaneously.

The specific embodiment
The structure of an embodiment of the utility model, as Fig. 1, Fig. 2, shown in Figure 3, a kind of pair of light source tunnel illuminating lamp comprises loose diffuser 1, radiating shell 2, sealing joint strip 3, baffle plate 4, constant-current source 5, circuit board 6, side plate 7, louvre 8, radiating fin 9.Be covered with radiating fin 9 at the back side of radiating shell 2, diffuser 1 is suitable with radiating shell 2, is installed on the radiating shell 2 by sealing joint strip 3, also is provided with baffle plate 4 in the both sides of radiating shell 2, baffle plate 4 adopts screw to be connected with radiating shell 2, has many louvres 8 on baffle plate 4.In radiating shell 2, be provided with two circuit boards 6, on circuit board 6, high-power LED is installed, the quantity of LED is installed according to the size and the actual needs of the individual power of LED, the circuit board 6 that LED is installed adopts aluminium base, after heat-conducting glue fat is coated at the back side of aluminium base, directly be mounted on the installed surface of radiating shell 2, side at radiating shell 2 also is equipped with constant-current source 5, the quantity of constant-current source 5 is identical with circuit board 6 quantity, the input of every block of led circuit plate 6 links to each other with the output of each self-corresponding constant-current source 5, the input of constant-current source 5 passes radiating shell 2 backs and is connected with the time control circuit output end, the time control circuit input be connected with power supply, last, for reinforcing product, be convenient to install and consideration attractive in appearance, at radiating shell 2 both sides of sealing joint strip 3 are installed, are provided with side plate 7.
At present, employed LED Tunnel Lamp is merely able to provide for the tunnel illumination of single power, but under the actual conditions, when the vehicle of running at high speed passed through the tunnel, if the inside and outside difference in brightness in tunnel is excessive, then the driver was difficult to adapt to the contrast of black and white environment, form " black-hole effect ", thereby cause danger.Therefore, the illuminating lamp in tunnel should provide the illumination of the big brightness of high power by day, and then should provide the illumination of small-power low-light level night, and the inside and outside difference in brightness in tunnel is reduced, and could satisfy the requirement that the driver conforms like this, reduces the driving risk.Control circuit was realized automaticallying switch when the utility model adopted the light-emitting device of two groups of different capacities to pass through, and took turns to operate, and had well solved this problem.And the common LED Tunnel Lamp heat that produces that works long hours is dispersed slow problem, also because the utility model adopts the circuit board that LED will be housed directly to be mounted on the radiating shell surface, the radiating shell back side is covered with radiating fin, two side shields have the structure of louvre, and make heat dissipation problem obtain solution.
The light angle of departure of LED is very little, and the promptly luminous directionality that has is to illuminating product, the illumination of different purposes requires different, and light beam requires have certain scope, existing technology generally to adopt lens to solve this problem, the lens of the different Qu Guangdu of LED pipe adapted of different qualities, interchangeability is bad.For addressing this problem, the utility model adopts the method for the reasonable combination of built-in different rising angle LED to solve, and cost is low, has saved lens.Simultaneously, the utility model adopts adhesive tape sealing between diffuser and radiating shell, has improved the reliability that connects, and also makes light fixture improve degree of protection.
