Abstract
The utility model relates to an energy saving signal lamp whose structure is that a connection board which is connected with an indicating lamp is arranged in a casing whose upper and lower openings are connected with an upper and a lower end covers and a lampshade; the indicating lamp uses a light emitting diode with micro power consumption and high brightness and is connected with a power supply through a control circuit. The signal lamp has the advantages of low energy consumption, wide working voltage scope and long service life.
Description
The utility model relates to a kind of signal lamp, specifically a kind of signal lamp with energy-saving effect.
Existing signal lamp is that terminal block is installed in housing, connects indicator light on the terminal block, and the housing upper and lower opening connects upper and lower end cap and lampshade, and indicator light is incandescent lamp or neon bulb.The incandescent lamp signal lamp is to utilize transformer step-down power supply, and power consumption is bigger, about 2.6 watts.The neon bulb signal lamp is to connect and power supply after neon bulb is connected in series a divider resistance, and its power consumption is about 0.8 watt.Because the luminescent lifetime of neon bulb is extremely short, after using one month continuously, its luminosity does not just reach requirement far away, so the use of incandescent lamp signal lamp is just very general, and power consumption is also just very big.
The purpose of this utility model just provides a kind of energy-saving signal lamp, with energy savings, improves useful life.
The utility model is achieved in that on by housing, terminal block, indicator light, end cap and lampshade etc. connect into up and down signal lamp, as indicator light, light-emitting diode is connected with power supply by control circuit with light-emitting diode.Like this, utilize little power consumption performance of light-emitting diode to realize that signal lamp is energy-conservation.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2, Fig. 3 are two kinds of embodiment of control circuit.
As shown in Figure 1, terminal block 2 is installed in the housing 1, the top layout control circuit of terminal block also is connected with light-emitting diode 3, the underrun screw 4 of terminal block is connected with binding post 5, the housing upper and lower opening connects upper end cover 6 and bottom end cover 7, upper end cover is suitable for reading to connect lampshade 8 by nut 9, covers indicator light.
Control circuit can have two kinds of implementations, as shown in Figure 2 a kind of, capacitor C 1 is in parallel with resistance R, meets rectifier D again, the output of rectifier and meet voltage-stabiliser tube DW and capacitor C 2 after, cross-over connection is in the two ends of LED.This control circuit after rectification again, voltage stabilizing, the filtering, becomes direct current to alternating current through capacitance current-limiting, supplies with light-emitting diode.This control circuit is suitable for the use of high-voltage AC signal lamp.And, has effect of saving energy simultaneously because the adding of capacitor C 1 has improved power factor.
The second way of control circuit as shown in Figure 3, resistance R is connected to the input of rectifier D, the output of rectifier D and connect voltage-stabiliser tube DW and capacitor C after, cross-over connection is in the two ends of LED.This control circuit after rectification again, voltage stabilizing, the filtering, becomes the low-voltage DC that uses for light-emitting diode through electric resistance partial pressure.This control circuit is suitable for the use of low pressure alternating current-direct current signal lamp.
Light-emitting diode and supporting control circuit thereof that the utility model utilizes little power consumption, height to measure are formed signal lamp, make power consumption reduce to 0.08 to 0.4 watt, and be energy-conservation more than 50%, and the scope of operating voltage is widened.The light-emitting diode life-span itself is long, thereby prolong the useful life of signal lamp greatly.
