An embodiment of the present disclosure discloses a track light, as shown in
The guide track 1 is used as a basic structure of the track light and is configured for fixing the driving power source 2 and the light source 3; and meanwhile, the guide track 1 also provides power for the driving power source 2. In particular, as shown in
Herein, the track housing 10 is generally an aluminum extruded housing which is good in appearance, high in structural strength, favorable in molding process and relatively good in overall performances. An accommodating cavity 10a is formed by being surrounded by the track housing 10; the accommodating cavity 10a includes a connection opening 100 in the thickness direction Z and a cavity bottom 102 opposite to the connection opening 100; the accommodating cavity 10a further includes two cavity walls 104 adjacent to the connection opening 100 in the width direction Y and oppositely disposed. The insulating members 12 are configured for fixing the conductive cables 14 and isolating electric energy to avoid short circuits. In particular, the insulating members 12 are fixedly disposed in the accommodating cavity 10a; in this case, the insulating members 12 can be fixedly disposed on the cavity bottom 102; the insulating members 12 can also be fixedly disposed on the cavity walls 104. The side, facing to the center of the accommodating cavity 10a, of the insulating members 12 are provided with cable slot 120, and the conductive cables 14 are fixedly disposed in the cable slot 120. The conductive cable 14 itself is provided with exposed conductive surface extending in the length direction X, and electric energy can be transmitted at any point on the conductive surface. It should be noted that, in some embodiments, it is possible that the track housing 10 is made of an insulating material; in this case, it is possible that the insulating members 12 are directly fixed on the track housing 10, without provision of the conductive cables 14.
In the present embodiment, the driving power source 2 is configured for obtaining electric energy from the guide track and transmit electric energy to the light source 3. In particular, as shown in
The driving board 28 is also mounted in the driving housing 20 and is configured for switching and controlling the power source. In order to conveniently mount the elastic conductive terminals 22 and the driving board 28 into the driving housing 20, the driving housing 20 in the present embodiment can be divided into two parts, that is, an upper housing 20a and a lower housing 20b; and the two parts are connected by a structure such as a screw and a buckle.
As shown in
The present embodiment, the cable slots 120 and the elastic conductive terminals 22 can be provided with guide surfaces for cooperation. When the driving power source 2 is placed into the accommodating cavity 10a through the connection opening 100, with the gradual deepening of the driving power source 2 into the accommodating cavity 10a, the elastic conductive terminals 22 are capable of retracting towards the inside of the driving housing 20 under the guide of the guide surfaces; and the elastic conductive terminals 22, by virtue of its elasticity, can be re-popped out and extend into the cable slots 120 in the width direction Y after crossing the guide surfaces, to electrically connected with the conductive cables 14. The process of electric connection between the driving power source 2 and the guide track 1 is very simple, so that the assembly time is greatly shortened.
The output terminal 24 is disposed at one side of the driving housing 20 in the thickness direction Z and is electrically connected with the elastic conductive terminals 22. For example, the elastic conductive terminals 22 and the output terminal 24 are electrically connected with the driving board 25 at the same time.
As shown in
The conductive sheets 224 may be provided with assembly gaps 224a, and the conductive pins 220 extend into the assembly gaps 224a, in this way, the conductive sheets 224 can be at least abutted and matched with the abutting parts 220a from two sides of the conductive pin 220; and therefore, the stability of electric connection can be improved. In order to fix the conductive sheets 224, the terminal guide slots 200 can be provided with clamping connection openings 200a; and the conductive sheet 224 is in clamping connection with and fixedly disposed in the clamping connection opening 200a. In addition, two ends of the conductive sheet 224 can also be bent or folded, so that the conductive sheet 224 become into a three-dimensional structure from a sheet to further improve the stability.
In the present embodiment, the guide surfaces can be disposed in the cable slots 120 only; for example, edges of clamping hooks of the cable slots 120 are designed to be first guide surfaces 120a which are arc-shaped or obliquely extend. The guide surfaces can also be disposed on the elastic conductive terminals 22 only; for example, ends of the conductive pins 220 are designed to be second guide surfaces 220b which are arc-shaped. Of course, it is possible that the first guide surfaces 120a and the second guide surfaces 220b present at the same time, so that a more excellent guide effect is provided. Moreover, the specific shapes of the guide surfaces in the present embodiment are not particularly limited as long as a guide function is achieved.
A circuit is required to be formed for electric connection; and therefore, two electrodes with opposite electric properties are generally required to be connected at the same time. In the present embodiment, in order to improve the safety, a single one conductive cable 14 can be only used as one electrode. Therefore, in order to form the circuit, the conductive cables 14 in the present embodiment include first conductive cables 14a and second conductive cables 14b which have opposite electric properties; the first conductive cable 14a and the second conductive cable 14b are required to be mutually staggered in the thickness direction Z; that is, they are different in distance from the connection opening 100. The elastic conductive terminals 22 also include first elastic conductive terminals 22a and second elastic conductive terminals 22b; the first elastic conductive terminal 22a and the second elastic conductive terminal 22b can have the identical structure, but are also required to be mutually staggered in the thickness direction Z. When the driving power source 2 is mounted at a preset position, the first elastic conductive terminals 22a are electrically connected with the first conductive cables 14a, and the second elastic conductive terminals 22b are electrically connected with the second conductive cables 14b, so that a connection circuit is formed.
Furthermore, in order to improve the stability of electric connection, two first conductive cables 14a and two second conductive cables 14b can be disposed at the same time in the present embodiment, the two first conductive cables 14a are oppositely disposed in the width direction Y, and the two second conductive cables 14b are also oppositely disposed in the width direction Y.
Meanwhile, on the driving power source 2, the number of the first elastic conductive terminals 22a and the number of the second elastic conductive terminals 22b are both two; the two first elastic conductive terminals 22a are disposed back to back in the width direction Y and are electrically connected with different first conductive cables 14a respectively; the two second elastic conductive terminals 22b are also disposed back to back in the width direction Y and are electrically connected with different second conductive cables 14b respectively. Structures for fixing the elastic conductive terminals 22 at two sides can be identical or different as long as there are no substantial influences to electric connection property. For example, the elastic conductive terminals 22 can be fixedly disposed by the insulating members 12 respectively disposed at two sides.
In this way, the driving power source 2 can be electrically connected with the two separately disposed elastic conductive terminals 22 at the same time when extending into the accommodating cavity 10a, which is equivalent to that two circuits connected in parallel are formed; therefore, the safety can be increased exponentially. The insulating members 12 can be fixed on the cavity walls 104 in a clamping connection way; for example, the walls 104 are provided with first clamping slots 104a, and the insulating members 12 are clamped inside the first clamping slots 104a. For example, when the driving power source 2 enters into the accommodating cavity 10a, at each of two opposite sides of the driving power supply 2 in the width direction Y, the first conductive cable 14a and the second conductive cable 14b can be electrically connected with the first elastic conductive terminal 22a and the second elastic conductive terminal 22b respectively.
In the present embodiment, in order to rapidly mount the driving power source 2, the cavity bottom 102 of the guide track 1 can be provided with first magnetic members 16. Similar to the way of fixing the insulating members 12, the first magnetic members 16 can be clamped and fixed on the cavity bottom 102 by the second clamping slots 102a provided on the cavity bottom 102. Meanwhile, second magnetic members 26 are provided inside the driving power source 2; the second magnetic members 26 can be fixed at the side of the driving housing 20 facing away from the output terminal 24.
When the driving power source 2 is placed into the guide track 1 through the connection opening 100, the first magnetic members 16 and the second magnetic members 26 are capable of generating magnetic adsorption effects so as to be rapidly close to each other and finally fixedly connected together. During magnetic adsorption, electric connection between each of the elastic conductive terminals 22 and each of the conductive cables 14 can also be automatically completed. When the position of the driving power source 2 is required to be moved, it can be realized just by pulling the driving power source 2 against friction force. In the present embodiment, both the first magnetic members 16 and the second magnetic members 26 can be magnets; however, the cost is relatively high. Preferably, the first magnetic member 16 can adopt magnetic metal plate such as iron plate; and the magnetic metal plate can extend to any position of the guide track 1 in the length direction X; and the second magnetic members 26 adopt magnet such as magnetic stone; and the magnetic metal plate is adsorbed by the magnets. The magnetic metal plate is low in price; and therefore, the cost can be effectively reduced. The magnets can be fixed on the driving housing 20 by structure such as clamping hook.
The light source 3 can adopt a spotlight, a downlight and the like or adopt a linear module; the light source 3 of linear module generally further includes a lens 34 configured for distributing light for the light emitting component 30. In order to fix the lens, structures such as clamping bars 104b can be disposed on the cavity walls 104 to clamp and fix the lens 34; and the lens 34 can cover the connection opening 100 after being fixed. In this case, the light emitting component 30 can be fixedly connected with the lens 34, so that the structural stability of the light emitting component 30 and the lens 34 is improved.
