The LED tunnel lamp comprises a lamp disk shell, a plurality of LEDs in the lamp disk shell and a LED drive power supply, wherein the lamp disk shell is composed of an upper cover plate like the rectangular board and a lower rectangular bottom plate. A flat plate shaped reflection layer is embedded on the lower bottom plate and the LEDs are arranged on the back of the reflection layer in the matrix and a flat plate shaped radiator is also fixed on the lower bottom plate and the radiation fins of the flat plate shaped radiator extend downwards. The prior tunnel lamp is improved to effectively solve the defects that the bad radiation, many welding-points, bad permeability rate and high encapsulation requirement. The led tunnel lamp has features of very good radiation effect and water proof and dust proof and is especially suitable for tunnel lighting.

Description

A kind of LED Tunnel Lamp

Technical field

The utility model relates to field of illuminating lamps, relates in particular to the LED Tunnel Lamp that a kind of LED is applied to lighting use.

Background technology

LED has high utilization rate of electrical, and the life-span is long, and power is little, and therefore, exploitation uses LED to become the industry first-selection as the high-brightness lighting lamp of light-emitting component.The heat that LED produces during because of its work is less, and luminous efficiency is higher, is regarded as cold light source.The LED Tunnel Lamp is made up of substrate, lens and the cooling system etc. of band LED, compares with traditional incandescent lamp, fluorescent lamp, and its electric energy can reach more than 90%.China is used for nearly 2,500 hundred million degree of electric power of road lighting present every year, if wherein have 1/3 to adopt the LED illumination, so annual 80000000000 degree that just can economize on electricity are equivalent to the annual electricity generating capacity in the Yangtze River Gorges.

Existing LED Tunnel Lamp has following shortcoming: the one, and the heat that LED crystal grain is produced, mode with heat point source is dispelled the heat to all directions, the sectional area of its heat radiation is little, can't reach fast and conduct heat in large area to heat abstractor, be easy to be accumulated in led chip inside, cause chip temperature too high and cause light decay or burn out; The 2nd, each encapsulation unit must weld 2 positive and negative contacts, many, the processed complex of solder joint, and the quality control difficulty is big; The 3rd, the encapsulation of led light source chip has frame, the penetrating rate of the light of the weak LED crystal grain of meeting; The 4th, the conditional request height of LED encapsulating material.

The utility model content

The purpose of this utility model is to utilize existing Tunnel Lamp structure, a kind of LED Tunnel Lamp of improveing the route of light source and light and designing, overcome the deficiency of above-mentioned existence, provide a kind of easy to use, reliable, can modularization, make led chip illumination output optimization, improve the luminance of Tunnel Lamp and the LED Tunnel Lamp of a kind of new structure of designing.

The utility model adopts following technical scheme:

LED Tunnel Lamp of the present utility model comprises a lamp panel shell, is arranged at a plurality of LED and a LED driving power in the lamp panel shell, and described lamp panel shell is made up of a lower shoe that is similar to the upper cover plate of rectangle platform and the rectangle under it.Wherein, inlay a flat reflector layer on the lower shoe, described LED arranged in matrix is in the back side of described reflector layer, and described lower shoe is also fixed a tabular radiator, and the radiating fin of described tabular radiator extends downwards.

Further, described lower shoe and be positioned at the LED top position and be provided with a transparent lamp shade.

Further, described lower shoe is provided with buckle for the edge with transparent lamp shade, by buckle described transparent lamp shade is fixed on the lower shoe.

Further, be provided with sealing ring between described lower shoe and the transparent lamp shade.

Further, be provided with the thermal conductive silicon glue-line between described LED and the reflector layer.

Further, described reflector layer is the metal luminescent layer, and is shaped as rectangle.

The utility model adopts as above technical scheme, and present Tunnel Lamp is improved, and solves effectively that poor heat radiation, many, the penetrating rates of solder joint are not good, encapsulation requires high a plurality of defective.The utility model has realized that a kind of radiating effect is excellent, the LED Tunnel Lamp of water proof and dust proof, is specially adapted to tunnel illumination.

The specific embodiment

Now with the specific embodiment the utility model is further specified in conjunction with the accompanying drawings.

Consult Fig. 1, Fig. 2 and shown in Figure 3, LED Tunnel Lamp of the present utility model, comprise a lamp panel shell,

Consult Fig. 1, Fig. 2 and shown in Figure 3, LED Tunnel Lamp of the present utility model, comprise a lamp panel shell, be arranged at a plurality of LED and a LED driving power in the lamp panel shell, described lamp panel shell is similar to the upper cover plate 1 of rectangle platform by one and the lower shoe 2 of the rectangle under it is formed.Wherein, inlay a flat reflector layer 4 on the lower shoe 2, described LED9 arranged in matrix is in the back side of described reflector layer 4, and described lower shoe 2 is also fixed a tabular radiator 8, and the radiating fin 81 of described tabular radiator 8 extends downwards.Its radiating fin 81 has superior radiator structure, high efficiency Heat Conduction Material; Adopt aluminium alloy fin and superalloy heat pipe.Its unique the place ahead Natural Heat Convection structural design fin is downward, avoids piling up dust or bird dung because of the light fixture top, and then avoids causing thermal resistance to reduce radiating efficiency, causes light decay, thereby has reached best radiating efficiency.

Preferably, be provided with the thermal conductive silicon glue-line between described LED9 and the reflector layer 4.By the setting of tabular radiator 2 and thermal conductive silicon glue-line, the heat of LED can be delivered on the lamp panel shell, and by tabular radiator 2 heat be dispersed in the outside air quickly and go.

Preferably, described reflector layer 4 is metal luminescent layers, and is shaped as rectangle.The light that the luminescent layer of metal also not only can better emit LED9 collects in one, can strengthen the brightness of light, increases the irradiation distance of light, and possesses the effect of heat conduction simultaneously.
