Description

A kind of high power LED tunnel lamp

Technical field

The utility model relates to the lighting engineering in tunnel and the culvert, more particularly relates to a kind of high power LED tunnel lamp.

Background technology

In various tunnels and culvert,, therefore be used for Tunnel Lamp that tunnel and culvert throw light on and always be in rugged environment and work easy ageing and damage like this because high humidity, dust is many, vibration frequency is strong.And owing to lack natural lighting in the tunnel, Tunnel Lamp was often opened in 24 hours, more required Tunnel Lamp to have high reliability and energy-conserving and environment-protective.The light source of Tunnel Lamp is with fluorescent lamp and high-voltage gas discharging light now, and energy utilization rate is lower, and energy consumption is big.In China; Along with rapid growth of economy, energy shortage contradiction manifests day by day, and country just actively implements the energy conservation priority policy; And " ligthing paraphernalia " listed in energy-conservation major fields; Under this social economy's background, the LED illuminating lamp of green high-efficient enters into people's the visual field gradually, becomes after incandescent lamp, fluorescent lamp, high-voltage gas discharging light " the 4th generation light source ".

The utility model content

To the defective that exists in the prior art, the purpose of the utility model provides a kind of energy-conserving and environment-protective, no stroboscopic, shock-resistant, difficult broken, safe and power saving high power LED tunnel lamp.

For achieving the above object, the utility model adopts following technical scheme:

A kind of high power LED tunnel lamp; Comprise shell, high-power LED chip, reflector, light-passing board and radiator, be provided with the fluorescent tube chamber that is the prismatoid structure in the said shell, said high-power LED chip is located at the end face in fluorescent tube chamber and is fixed on the top board of shell through insulating heat-conductive glue; Said reflector is located at the side in fluorescent tube chamber; Said light-passing board is located at the bottom surface in fluorescent tube chamber and is connected with shell is airtight, and said radiator is located at outside the shell, and is fixedly connected with the top board of shell.

Said radiator adopts the fin-shaped heat radiating fin structure.

Be interval with decorative pattern, small embossment or small rut on the said reflector.

Compared with prior art, the high power LED tunnel lamp of the utility model has that volume is little, energy consumption is low, the life-span is long, response is fast, anti-vibration, distinguishing feature such as shock-resistant, is desirable energy-conserving and environment-protective lighting engineering.Under the prerequisite of same illuminating effect, the high power LED tunnel lamp of the utility model is more energy-conservation 90% than conventional incandescent, and is more energy-conservation more than 50% than fluorescent lamp and high-voltage gas discharging light.Moreover the life-span of high-voltage gas discharging light is merely 0.5～1.5 ten thousand hour, and the high power LED tunnel lamp of the utility model then reaches 5～60,000 hours, and the service life of overlength and high reliability have been saved the hardship of frequent maintenance.And the LED Tunnel Lamp of use DC driven does not have stroboscopic, uses safer.Radiator adopts the fin-shaped heat radiating fin structure, is provided with the space between the adjacent fin-shaped fin, and the radiator convection current is good like this, rapid heat dissipation.

Description of drawings

Fig. 2 is the structural representation of the radiator of the utility model.

The specific embodiment

Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and embodiment.

See also Fig. 1, a kind of high power LED tunnel lamp shown in Figure 2; Comprise the radiator 4 of processing shell 1, high-power LED chip 2, reflector 3, light-passing board (not shown) and adopting the fin-shaped heat radiating fin structure by cast aluminium; Be provided with in the shell 1 and open wide the fluorescent tube chamber 5 that is the prismatoid structure that is provided with; High-power LED chip 2 is located at the end face in fluorescent tube chamber 5 and is fixed on the top board of shell 1 through insulating heat-conductive glue; Reflector 3 is located at the side in fluorescent tube chamber 5, light-passing board be located at fluorescent tube chamber 5 the bottom surface and with 1 airtight connection of shell, so just make fluorescent tube chamber 5 structure for sealing.Radiator 4 is located at outside the shell 1, and is fixedly connected with the top board of shell 1.Evenly be interval with decorative pattern (not shown), small embossment (not shown) or small rut (not shown) on the reflector 3, in order to prevent to produce dazzle.The sidewall of reflector 3 is planar structure or cancave cambered surface structure.

Those of ordinary skill in the art will be appreciated that; Above embodiment only is the purpose that is used for explaining the utility model; And be not with the qualification of doing the utility model; As long as in the essential scope of the utility model, in the scope to the variation of the above embodiment, claim that modification all will drop on the utility model.
