Abstract
The utility model discloses an LED tunnel lamp with cooling grooves in a casing. The tunnel lamp comprises a lamp bracket, a light-emitting body, a power control circuit board, a fixed support and an installation support. The light-emitting body is fixed and installed on the lamp bracket, the fixed support and the installation support are in hinge connection, and the tunnel lamp is installed at the top of a tunnel or on the lateral wall of the tunnel through the installation support. A set of cooling fins are arranged on the lateral face, away from the light-emitting body, of the lamp bracket, the cooling grooves are formed between two adjacent cooling fins, the direction of the cooling grooves is parallel to the extending line of the length direction of the tunnel, the light-emitting body is arranged on the lamp bracket without a gap, and the power control circuit board is arranged on the installation support. The light-emitting body is an LED bulb. The LED tunnel lamp with cooling grooves in the casing is good in cooling effect, reduces water mist, improves light source quality, prolongs the service life of the LED bulb, reduces working load of daily maintenance, and reduces cost so as to achieve the aim of energy saving and environment friendliness.
Description
Technical field
The utility model relates on a kind of shell the LED tunnel lamp with radiating groove.
Background technology
In order to meet the illumination needs in tunnel, the power ratio of the illuminator of tunnel lamp is larger, sends very large heat when meeting lighting requirement, tunnel lamp temperature is on every side raise, because humidity ratio in tunnel is larger.The radiating effect of current tunnel lamp is bad, and the high temperature of tunnel lamp causes water smoke to produce, and makes to produce one deck steam on the transparent surface of illuminator of tunnel lamp, obviously reduces the illumination of light source, year in and year out, reduces equally the service life of light fixture.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of perfect heat-dissipating is provided, and reduces water smoke and produces, and keeps the light source quality, improves on the shell in service life the LED tunnel lamp with radiating groove.
The purpose of this utility model is achieved by following technical proposals: described tunnel lamp comprises lamp bracket, illuminator, power control circuit plate, hold-down support and erection support, described illuminator is fixed on lamp bracket, and hold-down support and erection support are for being hinged; Described tunnel lamp is arranged on the top or sidewall in tunnel by erection support; One group of fin is set on the side of the backward luminous body of described lamp bracket, form radiating groove between adjacent two fin, and the direction of radiating groove is parallel with the extended line of the length direction in tunnel; Described illuminator is arranged on lamp bracket and does not stay gap; Described power control circuit plate is arranged on erection support.
Described illuminator is the LED bulb.
Described hold-down support is U-shaped structure, and two wing limits are arranged on respectively the end of two fin.
Described erection support is U-shaped structure, and a crossbeam is set in U-shaped structure, and the power control circuit plate is installed on crossbeam.
The utility model compared with prior art, have the following advantages: the structure advantages of simple, good heat dissipation effect, under extraneous zero temperature, 40 degree Celsius are under the environment of 50 degree Celsius above freezing, and tunnel lamp and near the temperature it can be consistent substantially, thereby greatly reduce the generation of water smoke, improve the light source quality, extended the service life of LED bulb, reduced the workload of regular maintenance, reduce costs, reach the purpose of energy-conserving and environment-protective.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
The A-A sectional structure enlarged diagram that Fig. 2 is Fig. 1;
In figure: 1-lamp bracket, 2-illuminator, 3-radiating groove, 4-fin, 5-hold-down support, 6-power control circuit plate, 7-erection support, 8-crossbeam.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Referring to accompanying drawing: described tunnel lamp comprises lamp bracket 1, illuminator 2, power control circuit plate 6, hold-down support 5 and erection support 7, and described illuminator 2 is fixed on lamp bracket 1, and hold-down support 5 and erection support 7 are for being hinged; Described tunnel lamp is arranged on the top or sidewall in tunnel by erection support 7; On the side of the backward luminous body 2 of described lamp bracket 1, one group of fin 4 is set, form radiating groove 3 between adjacent two fin 4, and the direction of radiating groove 3 is parallel with the extended line of the length direction in tunnel; Described illuminator 2 is arranged on lamp bracket 1 and does not stay gap; Described power control circuit plate 6 is arranged on erection support 7.
Described illuminator 2 is the LED bulb.
Described hold-down support 5 is U-shaped structure, and two wing limits are arranged on respectively the end of two fin 4.
Described erection support 7 is U-shaped structure, and a crossbeam 8 is set in U-shaped structure, and power control circuit plate 6 is installed on crossbeam 8.
Embodiment 1:
One group of fin 4 is set on the side of the backward luminous body 2 of lamp bracket 1, form radiating groove 3 between adjacent two fin 4, and the direction of radiating groove 3 is parallel with the extended line of the length direction in tunnel; Illuminator 2 is the LED bulb, be fixed on lamp bracket 1, and illuminator 2 is arranged on lamp bracket 1 and does not stay gap, in order to allow the heat of illuminator 2 be delivered to greatest extent on lamp bracket 1, then by fin 4 and radiating groove 3, distributes; Hold-down support 5 is arranged on lamp bracket 1, and hold-down support 5 and erection support 7 are for being hinged; Tunnel lamp is arranged on the top or sidewall in tunnel by erection support 7; Described described power control circuit plate 6 is arranged on erection support 7.
Embodiment 2:
Substantially the same manner as Example 1, different: hold-down support 5 is U-shaped structure, and two wing limits are arranged on respectively the end of two fin 4.
Identical, different with the basis of embodiment 1,2 respectively: erection support 7 is U-shaped structure, and a crossbeam 8 is set in U-shaped structure, and power control circuit plate 6 is installed on crossbeam 8.
The utility model adopts two cover heat dissipation technology schemes:
1, the heat of illuminator 2 is delivered on lamp bracket 1 to greatest extent, then by fin 4 and radiating groove 3, distributes.
2, power control circuit plate 6 breaks away from lamp bracket 1, and its dissipation of heat is in atmosphere.
