Description
Technical field
The utility model relates to a kind of unit switch, relates in particular to a kind of unit switch with background light for automobile.
Background technology
Combined switch for automobile is installed on the car steering tube column, is comprised of in order to light, the signal of controlling automobile, the switch of controlling the parts such as electrical equipment a plurality of.Be carved with switch gear symbol or literal at unit switch, these symbols or literal will not see Chu after dim light or darkness, be not easy to driver's operation.Open day be that on 07 03rd, 2002, publication number are the patent documentation of CN 2498529Y, it discloses the technical scheme that name is called a kind of air-conditioning remote control, it uses fluorescent material as the sign flag of remote controller buttons, has so just solved the shortcoming that remote controller buttons is awkward when light is darker.But fluorescent material has a lot of defectives, if former because use the fluorescent material of rays excite type, the rays excite fluorescent material that utilizes radioactive substance constantly to send is luminous for a long time, will mix radioactive substance in fluorescent material, this class material poisonous and harmful contaminated environment; If use photo-induced energy storage fluorescent material, then this class material is subjected to strong illumination blackout apt to deteriorate, and the phenomenons such as weak point persistence, infrared cancellation occur easily.Therefore, this technical scheme is for combined switch for automobile and inapplicable.
Summary of the invention
The utility model main purpose is to provide a kind of combined switch for automobile with background light, increases background light at unit switch, makes the driver clearly see switch and each gear of unit switch.
The utility model is mainly solved by following technical proposals for the prior art problem, a kind of combined switch for automobile with background light, each switch mark of this unit switch and gear sign are made of background light and symbol sheet, background light is fixed on switch mark place and the gear sign place of unit switch, the symbol sheet covers on the background light, and described symbol sheet is the light-passing plastic thin slice with switch mark symbol or gear identifier.This technical scheme is to place the sign that is made of background light and symbol sheet at switch mark place and the gear sign place of unit switch, solves the switch of unit switch and the problem that gear does not see.Such as master lighting switch, AUTO shelves, dipped headlights shelves, position lamp shelves, master lighting switch OFF shelves, Rear Fog Lamp shelves, front fog lamp shelves etc., with the standard symbol printing (fixing) of these switches and gear on the symbol sheet, consisting of one by one with background light, sign is fixedly mounted on respective switch and the gear, when ambient light is not enough, open background light, make background light illuminate the symbol sheet, the driver can be clear that switch and gear when the operative combination switch.
As preferably, a background light is a LED.LED is light-emitting diode, long working life, and power consumption is little, and brightness is high.
As preferably, LED is adopting surface mounted LED.SMD Light-Emitting Diode have can adhesive type install, volume is little, angle of scattering is large, uniformity of luminance is good, high reliability, be highly suitable on the unit switch as a setting lamp and install, use.
As preferably, a plurality of LED series connection are connected in series current-limiting resistance again and consist of the background light circuit, connect positive source behind mains switch of positive pole serial connection of background light circuit, background light circuit negative pole connects power cathode, the number of background light circuit is during more than one, the background light circuit is in parallel in the same way, and the background light circuit anode after the parallel connection is connected to positive source by described mains switch.Determine the number of LED in each background light circuit according to the forward operating voltage of supply voltage and each LED; such as be 12V at supply voltage, when LED forward operating voltage is 3V; need 4 LED series connection; because the unsteadiness of supply voltage; need to be connected in series again a current-limiting resistance with protection LED, so just consist of a background light circuit by 4 LED and a current-limiting resistance.When LED is more, can consist of a plurality of such background light circuit, equidirectional between a plurality of background light circuit (anodal and anodal corresponding, negative pole is corresponding with negative pole) is connected in parallel; The LED number is few in a background light circuit occurring, when total operating voltage is lower than supply voltage after the series connection, uses equally current-limiting resistance by increasing resistance value adjusted, so that the LED trouble free service.Here, use the background light circuit of LED series connection, and do not adopt the single led circuit arrangement that adds divider resistance or add the dividing potential drop diode, be conducive to simplify circuit structure, reduce cost of manufacture and energy resource consumption.
As preferably, mains switch is the side-marker lamp switch.The background light circuit is in parallel with side-marker lamp, jointly uses the side-marker lamp switch, has also opened simultaneously background light when opening side-marker lamp, uses easily.
The beneficial effect that the utility model brings is that the unit switch that has increased background light and symbol sheet formation identifies, and makes the driver can clearly see switch and the gear of unit switch, has promoted the backlight quality of car load at the steering wheel place, has promoted the vehicle class.
Description of drawings
Fig. 1 is a kind of schematic diagram of the present utility model;
Fig. 2 is a kind of backlight circuit theory diagrams of the present utility model.
Among the figure: the 1st, combined switch for automobile, the 2nd, master lighting switch sign, the 3rd, AUTO shelves sign, the 4th, dipped headlights shelves sign, the 5th, position lamp shelves sign, the 6th, Rear Fog Lamp shelves sign, the 7th, master lighting switch OFF shelves sign, the 8th, fog lamp switch OFF shelves sign, the 9th, front fog lamp shelves sign, K is mains switch, and D1 to D8 is LED, and R1, R2 are current-limiting resistances.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment: as shown in Figure 1 and Figure 2, the utility model is a kind of combined switch for automobile with background light, the symbol sheet is the PC(Merlon) plastic tab uses standard symbol in the coating printing, LED sticks on the place that combined switch for automobile 1 needs to place sign, cover symbol sheet on LED.The installation of LED and symbol sheet, technique is done integral installation and is connected with circuit in accordance with regulations when unit switch is produced.In Fig. 1, sign comprises master lighting switch sign 2, AUTO shelves sign 3, dipped headlights shelves sign 4, position lamp shelves sign 5, Rear Fog Lamp shelves sign 6, master lighting switch OFF shelves sign 7, fog lamp switch OFF shelves sign 8, front fog lamp shelves sign 9.
Figure 2 shows that circuit theory diagrams, because 8 signs are arranged, so in respect of 8 LED(adopting surface mounted LEDs), selection work voltage is the LED of 3V, and supply voltage is 12V, and D1 to the D4 series limiting resistor R1 that connects again is a background light circuit, D5 to D8 connects again, and series limiting resistor R2 is another background light circuit, after the parallel connection, positive terminal is connected to mains switch K in the same way for two background light circuit, negative pole end connect power cathode ().Mains switch K is the side-marker lamp switch in the present embodiment, and when opening side-marker lamp, background light is that D1 to D8 lights, and illuminates all signs.
So the utlity model has following characteristics: increased the unit switch sign that background light and symbol sheet consist of, made the driver can clearly see switch and the gear of unit switch, beautified environment backlight in the car.
