Abstract

The utility model discloses a light-changeable lamp bulb and a lamp holder. The utility model does not need any external device to realize functions that light is changed, light is gradually brightened, the service life of the lamp bulb is extended, etc. A plurality of groups of lamp filaments, corresponding lead wires, contact heads and contact spots are arranged in the lamp bulb and the lamp holder. The utility model also comprises a resistor which has the negative temperature characteristic, two symmetrical spacing light adjusting tracks on the lamp holder, etc. When the lamp bulb is rotated (positions of staples on the spacing light adjusting tracks on a lamp cap are changed), and the purpose can be obtained. The light-changeable lamp bulb and the lamp holder have the advantages of simple structure, long service life, and convenient usage.

Description

High-low lamp and socket

The utility model relates to ligthing paraphernalia, relates to a kind of bulb of being made up of many groups filament and negative temperature characteristic resistance particularly and reaches the socket that adapts with it.

Common incandescent lamp bulb is switched on when cold conditions, and impulse current is very big, is easy to the disintegration of filament, and at the energising initial stage dazzling sensation is arranged, and can't become light.Existing solution is to increase gradually bright, the purpose that becomes light and protection filament that some complicated control circuits are realized light on the basis of common bulb.This scheme will increase a lot of costs beyond doubt and consume lot of manpower and material resources, and the consumer also is not easy to accept.

Task of the present utility model provides a kind of high-low lamp and socket, and it can realize gradually bright, the requirement that becomes light and prolong its useful life of bulb easily.

The purpose of this utility model is achieved in that filament (3) in bulb (1). and (4). (5) reach and the corresponding lead-out wire of filament (6). and (7). (8). the contact that (9) are connected respectively (10). (11). (12). (13), have in the socket (16) and contact (10). (11). (12). (13) corresponding spring contact (10 ') (11 ') (12 ') (13 '), can push down the stator (19) of the incoming line of spring contact in addition. (20). (21) and negative temperature characteristic resistance (22) have fixedly bulb (1) and spacing spacing light modulation track (17) on the socket (16).

Because the above-mentioned structure of high-low lamp of the present utility model and socket, when just making power connection, electric current flows back to through negative temperature characteristic resistance, filament.Because very big during the resistance cold conditions of negative temperature characteristic resistance, after two ends added voltage, resistance value was opened to cheat gradually and reduced, almost nil at last (deciding on model) realized that light is gradually bright, also reduced the purpose of impulse current prestige evil filament simultaneously.Utilize to change corresponding contact, contact and the position of spacing bail on spacing light modulation track on lamp holder, the socket, can change filament and joint group number, also promptly realized becoming the purpose of light.After filament is many, burn one group or two groups, other can also continue use, so also prolonged the useful life of bulb.

The utility model is because of only needing to increase the resistance of several groups of filaments and the contact, contact and the series connection that adapt in original device, so structure is simple especially, the starting point does not lie in the outward appearance that changes original product simultaneously, so it does not have special requirement to manufacture craft yet.

Concrete structure of the present utility model is provided by following examples and accompanying drawing.

Fig. 1. Fig. 2 c is according to the high-low lamp that the utility model proposes and the end view of socket; Fig. 2 looks and top view at the end of socket; Fig. 3 is circuit theory diagrams.

Below in conjunction with details and the working condition of Fig. 1 .2.3 detailed description according to the concrete device that the utility model proposes.

This device comprises a bulb main body (1). lamp holder (2). and socket main body (16). socket clamp nut (15) and socket lid (18).Filament (3) is arranged in the bulb main body (1). filament (4). filament (5) and corresponding filament lead wire (6). (7). (8) and common wire (9).The contact (10) that is connected with filament is arranged on the lamp holder. (11). (12) and common (13) also have bail (14) fixing with socket and spacing usefulness on the lamp holder.The incoming line stator (19) that can push down spring contact is housed on the socket (16). (20). (21), negative temperature characteristic resistance (22) is housed between stator (19) and (20), also be equipped with and contact (10). (11). (12). (13) corresponding contact (10 '). (11 '). (12 ') and (13 '), also have on the limit of socket main body (16) with lamp holder on fixed limit bail (14), corresponding a pair of spacing track (17).

In the present embodiment, contact (13) join with contact (13 ') when lamp holder (2) inserts in the socket (16) and rotates first angle, (10) join with (10 '), filament (3) inserts power supply, realize gradually bright control as general bulb, contact (11) join with contact (11 ') when second angle of rotation, and filament (4) also inserts power supply and realized becoming for the second time light.In bulb, there are one group or two groups of filament to have no progeny, because contact (10 '). (11 '). (12 ') are in parallel, so as long as rotary lamp holder (2) can be connected remaining filament.
