[0030] Reference Figures 1 to 2 According to a first aspect of the present invention, a thin track light includes a lamp housing 100, a light source plate 200, and a lamp shade 300. The lamp housing 100 has a receiving groove 110 with its opening facing downward. The bottom wall of the receiving groove 110 is provided with a protruding heat-conducting part 111. The heat-conducting part 111 extends along the length direction of the lamp housing 100, and the side of the heat-conducting part 111 away from the receiving groove 110 has a heat dissipation groove 120. The heat dissipation groove 120 extends along the extending direction of the heat-conducting part 111. The lamp housing 100 is used for sliding connection with a guide rail. The heat dissipation groove 120 can form a heat dissipation and ventilation channel with the guide rail. The light source plate 200 is disposed in the receiving groove 110 and abuts against the heat-conducting part 111. The lamp shade 300 is disposed in the lamp housing 100 and covers the opening of the receiving groove 110. The light source board 200 abuts against the heat-conducting part 111, which can quickly and fully conduct heat to the heat-conducting part 111. The back of the heat-conducting part 111 has a heat dissipation groove 120, which can extend along the lamp housing 100. After the lamp housing 100 is installed on the guide rail, the heat dissipation groove 120 can form a heat dissipation and ventilation channel with the outside, which can quickly dissipate the heat of the heat-conducting part 111 through air exchange, and improve the heat dissipation effect in a limited space.
[0031] Specifically, the receiving groove 110 of the lamp housing 100 is used to install the light source board 200, and the bottom wall of the receiving groove 110 has a raised heat-conducting part 111. The heat-conducting part 111 can protrude in the middle of the bottom wall of the receiving groove 110 and extends along the length of the lamp housing 100. The light source board 200 abuts against the heat-conducting part 111. It can be understood that the heat-conducting part 111 can be stamped or extruded, so that the back of the raised heat-conducting part 111 is a recessed heat dissipation groove 120. The heat dissipation groove 120 also extends along the length of the lamp housing 100. Extending in the direction of degree, the lampshade 300 is installed on the lamp housing 100 to form a track light. The track light can be slidably installed on the guide rail, and the heat dissipation groove 120 and the guide rail form a heat dissipation and ventilation channel. Since the light source board 200 will generate heat when lighting, if it cannot be dissipated in time, it is easy to cause failure. By tightly abutting the light source board 200 and the heat-conducting part 111, heat can be quickly transferred to the heat dissipation groove 120. The heat dissipation groove 120 can ventilate and dissipate heat, and can quickly exchange heat to the air, which can improve the heat dissipation effect in a limited space.
[0032] Reference Figure 2 In some embodiments of this utility model, the sidewall of the heat dissipation groove 120 is provided with a protruding first heat dissipation strip 121. Specifically, the first heat dissipation strip 121 protrudes from the sidewall of the heat dissipation groove 120, so that the first heat dissipation strip 121 can dissipate heat in the heat dissipation ventilation channel, which can increase the contact area with air, thereby improving heat dissipation efficiency and further enhancing the heat dissipation effect.
[0033] Reference Figure 3 In some embodiments of this utility model, multiple first heat dissipation strips 121 are provided. The first heat dissipation strips 121 extend along the extending direction of the heat dissipation groove 120, and each first heat dissipation strip 121 is spaced apart along the depth direction of the heat dissipation groove 120. Specifically, multiple first heat dissipation strips 121 can be provided, and the thickness of each first heat dissipation strip 121 can be set to be smaller, which can further expand the heat dissipation area and improve the heat dissipation effect.
[0034] Reference Figure 4 In some embodiments of this utility model, the bottom wall of the heat dissipation groove 120 is provided with a raised second heat dissipation strip 122, which extends in the extending direction of the heat dissipation groove 120. Specifically, the bottom wall of the heat dissipation groove 120 may also be provided with a raised second heat dissipation strip 122, which can further expand the heat dissipation area and further improve the heat dissipation effect.
[0035] Reference Figure 4In some embodiments of this utility model, multiple second heat dissipation strips 122 are provided, and each second heat dissipation strip 122 is spaced apart along the width direction of the heat dissipation groove 120. Specifically, multiple second heat dissipation strips 122 can be provided, and each second heat dissipation strip 122 can be arranged at intervals so that air can pass through the gaps, thereby further expanding the heat dissipation area and further improving the heat dissipation effect.
[0036] In some embodiments of this utility model, the lamp housing 100 is made of metal. Specifically, the lamp housing 100 can be made of aluminum alloy, which has good heat transfer performance, is lightweight, and has a structure that meets usage requirements.
[0037] Understandably, the lamp housing 100 can also be made of other metal alloys.
[0038] Reference Figure 1 and Figure 5 In some embodiments of this utility model, the lamp housing 100 further includes a first end seat 130 and a second end seat 140. The first end seat 130 is connected to one end of the lamp housing 100, and the second end seat 140 is connected to the other end of the lamp housing 100. The first end seat 130 is provided with a first conductive head 131, and the second end seat 140 is provided with a second conductive head 141. Both the first conductive head 131 and the second conductive head 141 are electrically connected to the light source board 200, and the first conductive head 131 and the second conductive head 141 are used for electrical connection with the power supply part of the guide rail. Specifically, the first endplate 130 and the second endplate 140 can be installed at the end of the lamp housing 100, which is convenient for assembly. The first conductive head 131 can protrude from the side of the first endplate 130 to facilitate contact and electrical connection with the power supply rail of the guide rail. It can be understood that the first conductive head 131 can protrude from both sides of the first endplate 130. Similarly, the second conductive head 141 can protrude from the side of the second endplate 140 and protrude from both sides. The first conductive head 131 and the second conductive head 141 can be electrically connected to the light source board 200 through a cable. One of the first conductive head 131 and the second conductive head 141 can be connected to the live wire on the power supply rail, and the other can be connected to the neutral wire to realize the circuit switching.
[0039] It is understandable that the first conductive head 131 and the second conductive head 141 are offset in height direction.
[0040] Reference Figure 1 and Figure 5In some embodiments of this utility model, a first insertion structure 150 is provided between the first end seat 130 and the lamp housing 100, and a second insertion structure 160 is provided between the second end seat 140 and the lamp housing 100. The first end seat 130 can be connected to the lamp housing 100 through the first insertion structure 150, and the first conductive head 131 can be electrically connected to the light source board 200. The second end seat 140 can be connected to the lamp housing 100 through the second insertion structure 160, and the second conductive head 141 can be electrically connected to the light source board 200. Specifically, the first end seat 130 can be fixedly connected to the lamp housing 100 through the first insertion structure 150, and the first conductive head 131 can be electrically connected to the light source board 200 at the same time, which is simple to assemble. Similarly, the second end seat 140 can be fixedly connected to the lamp housing 100 through the second insertion structure 160, and the second conductive head 141 can be electrically connected to the light source board 200, which is relatively convenient to assemble.
[0041] Reference Figure 1 and Figure 5 In some embodiments of this utility model, the first plug-in structure 150 includes a first plug-in groove 151 and a first plug-in connector 152. The first plug-in connector 152 is disposed on the first end seat 130 and can be electrically connected to the first conductive head 131. The first plug-in groove 151 is disposed at one end of the lamp housing 100 and can be electrically connected to the light source board 200. The first plug-in connector 152 can be inserted into the first plug-in groove 151. The second plug-in structure 160 includes a second plug-in groove 161 and a second plug-in connector 162. The second plug-in connector 162 is disposed on the second end seat 140 and can be electrically connected to the second conductive head 141. The second plug-in groove 161 is disposed on the lamp housing 100 and can be electrically connected to the light source board 200. The second plug-in connector 162 can be inserted into the second plug-in groove 161. Specifically, the first connector 152 is made of conductive material, and the first insertion groove 151 has a conductive part that can be electrically connected to the light source board 200. The first conductive head 131 is electrically connected to the first connector 152. During assembly, the first connector 152 and the first insertion groove 151 can be electrically connected to the light source board 200 when they are plugged in and tightened. Similarly, the second connector 162 and the second insertion groove 161 have the same structure. When plugged in, the second conductive head 141 can be electrically connected to the light source board 200. The structure is simple and the installation is relatively convenient.
[0042] Reference Figure 1 and Figure 5In some embodiments of this utility model, a snap-fit connector 400 is also included. The snap-fit connector 400 is disposed on the first end seat 130 and / or the second end seat 140. The snap-fit connector 400 can be snapped onto the guide rail and slidably connected to the guide rail. Specifically, the snap-fit connector 400 can be installed on the first end seat 130, and the snap-fit connector 400 can protrude outward from the side of the first end seat 130. The snap-fit connector 400 can be at the same height as the second conductive head 141. The snap-fit connector 400 can snap onto and slidably connect with the power supply rail to further improve the connection stability of the track light and make the track light slide more smoothly.
[0043] It is understandable that the card connector 400 can be located on the second end seat 140, or it can be located on both the first end seat 130 and the second end seat 140.
