Abstract

The utility model relates to a radiating LED signal lamp. The utility model takes following measures toward a lamp disk. Firstly, a plurality of resistors with voltage division function are distributed uniformly around the peripheral core of a circular disk, and the distance between the resistors and a light emitting reflection board and a circuit board is 10-50MM, which can cause the utility model to radiate heat evenly; secondly, LED lamp tubes are arranged in the mode of concentric circle water wave, so the utility model has the advantages of high light emitting brightness, beautiful shapes and fluent air flow; thirdly, the light emitting reflection board and a lamp casing are provided with phi 3-phi 10MM holes, which can cause heat to exhale out of the lamp evenly. Compared with LED signal lamps in the prior art, the utility model has the advantages of high brightness and significantly extended service life.

Description

The LED signal lamp that can dispel the heat
Technical field
The traffic lights that the utility model relates to, particularly relevant is the signal lamp of light source with the light emitting diode.
Background technology
Widely used in the past signal lamp all is to adopt following structure: power supply, lamp housing, reflector, coloured lens, light source.Wherein the light source overwhelming majority is to adopt incandescent lamp and metal halogen tungsten lamp, through adjusting for many years substantial variation does not take place.Along with environment and economic development to improving constantly that means of transportation require, for reaching relative brightness, most of operation all is to adopt artificial the scouring, changes new light sources, simpler is exactly to change method such as powerful light source.Nowadays most of city begins to apply the signal lamp that LED is a light source, and LED itself adopts semi-conductive principle to make, and directly is welded in and does the series and parallel connection on the circuit board, adds resin sheet or resin lens, does sealing again.Such LED signal lamp itself all is by more than 100, even a hundreds of independent LED composition, and signal lamp is long-term used in the open air for adapting to, and must possess structures such as wind resistance, dirt, tide, rainwater, and above structure certainly exists following shortcoming:
Shortcoming one, conventional lamp can't satisfy the high requirement of brightness, maintain, safeguard, change parts (comprising light source) in addition all the year round, and energy consumption are higher, need to drop into a large amount of person properties and support.
Shortcoming two, the various structural configuration of LED signal lamp must cause in the long-term use, and the reduction of lamp panel internal heat dissipating effect causes local temperature too high, thereby causes light emitting diode internal heat resistance to increase, and makes its premature aging, increases unnecessary cost.
Shortcoming three, LED science and technology itself is fast-developing at present, the wafer and the various synthetic schemes that constitute improve constantly, luminous efficacy constantly promotes, but because the lamp box interior environment temperature is too high, do not have basic structural change again, it is aging that LED is accelerated, and the efficient performance performance of LED is not come out.
Summary of the invention
The signal lamp that the design makes removes normal housing, lamp plate, luminous and reflecting effect and control panel, is fixed on the pallet in the housing in addition.The lamp plate at luminous and reflective place relies on rubber seal to be fixed on the lamp housing panel, adopts corresponding cooling measure simultaneously, makes LED signal lamp energy consumption reduce, and the life-span prolongs, and has given full play to the advantage of the long-life, high brightness, low-power consumption etc. of efficient LED.
One of cooling measure: will have the resistance that plays the dividing potential drop effect in the electrical equipment now, and be evenly distributed on around the center of circle of disk.Do air flow passage with suitably partly staying in the lamp panel simultaneously, the heat that resistance produces evenly can be separated like this, modes such as the corresponding heat of utilization conduction are scattered heat.(see figure 3)
Two of cooling measure: on the basis of cooling measure one, the LED fluorescent tube is arranged in concentric circles ripples mode, drawn integral LED structure layout viewing earlier on microcomputer, then the display floater photoetching is formed, make wiring board, welding LED gets final product.It is unobstructed that whole like this luminous plaque brightness is even, moulding is perfect, air flows, and hot gas flows evenly in the whole dish, and radiating effect is obvious, greatly reduce the thermal resistance value of semiconductor LED micro-structural, make its electric current even, do not have frequent voltage change, prolong its service life.
This LED signal lamp contains circuit board, LED semiconductor light-emitting-diode, Transparent lamp shade, black lamp box, the seal that electronic component is housed.The resistance that plays the dividing potential drop effect in its electronic component evenly distributes, and at the center of luminous and reflector, reach the rear side housing section on every side and separate some uneven heat dissipation holes, its LED semiconductor light-emitting-diode boundling group arranges in concentric circles ripples mode.The heat that makes system produce when work significantly reduces, and effectively raises the work quality of LED signal lamp, and has prolonged the service life of LED signal lamp greatly.
Therefore the present invention is characterized as:
1, a kind of LED signal lamp that can dispel the heat, the resistance that plays the dividing potential drop effect in the electronic component is evenly distributed on around the center of circle of disk, is 10-50mm apart from luminous reflecting and wiring board distance.
2, according to above-mentioned 1, it is characterized by luminous and reflector center and around the appropriate location open Φ 3-Φ 5mm uneven heat dissipation hole, luminously open Φ 3-Φ 10mm uneven heat dissipation hole with reflector rear side lamp housing place.
3, according to above-mentioned 1, it is characterized by LED semiconductor light-emitting-diode boundling group and arrange in concentric circles ripples mode.
Description of drawings: Fig. 1 is a LED bundle pipes concentric circles ripples distribution floor map, and Fig. 2,3 is a LED signal lamp heat dissipation ventilation road structural representation.Wherein 1 is lampshade, and 2 is luminous and reflector, and 3 is the LED illuminator, and 4 is O-ring seal, and 5 is pallet, and 6 is divider resistance, the 7th, and binding post, 8 is the uneven heat dissipation hole.
The specific embodiment:
Example one: the LED signal lamp of getting the market buying compares, utilize one of cooling measure that 4 required in original structure circuit divider resistances are evenly connected in the circuit board, and be arranged in disc centre, luminous and the reflector 30mm of distance, apart from the centre position 20mm of pallet interior circuit board, simultaneously in conjunction with adopting cooling measure two.Get two groups altogether and do the contrast test.Testing time is six months, and consequently commercial and this device brightness is more or less the same, and power consumption is more or less the same; Testing time is 12 months, consequently commercially has 4 damages, and the brightness 8cd that on average descends, and 2 damages are arranged in this device, and brightness simultaneously on average reduces 6cd.
Example two: the same, on example one basis, in the centre position of luminous and luminous plaque and the on-uniform porosity that Φ 3-5mm is opened in the circumference corresponding position.Testing time is six months, and consequently commercial and this device brightness is more or less the same, and power consumption is more or less the same; Testing time is 12 months, consequently commercially has 4 damages, and the brightness 9cd that on average descends, and do not have in this device and damage, and brightness is even, on average reduces 5cd.
Example three: the same, on example two bases, between luminous and reflector and pallet, behind the pallet, open the on-uniform porosity of Φ 5-7mm on the side body respectively.Testing time is six months, and consequently commercial and this device brightness is more or less the same, and power consumption is more or less the same; Testing time is 12 months, consequently commercially has 5 damages, and the brightness 8cd that on average descends, and do not have in this device and damage, and brightness is even, on average reduces 4cd.
