Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more specifically to a general-purpose light source. Background Technology

[0002] LEDs, as a new light source, have been widely used in various lighting facilities due to their advantages such as energy saving and long lifespan. Existing lighting sources of this type typically use several different types of lamp holders, such as the traditional G24q-(1-7). In light sources constructed with these lamp holders, corresponding light source components are assembled and combined to form a single lamp model. However, this single-structure lamp holder can only assemble specific light sources and cannot adapt to various other light sources, thus reducing the applicability of the lamp holder.

[0003] Therefore, people have developed a lamp that can be adapted to multiple light sources, such as the Chinese invention patent with publication number CN204986535U, publication date January 20, 2016, entitled "A Universal Lamp". This lamp has good applicability by setting the light source assembly into multiple structures that can be selected according to needs. However, in this lamp, the light source assembly includes a light source and a lamp head and lamp holder that match the light source. This mode of setting the light source assembly into multiple structures requires manufacturers to design and produce multiple light sources, lamp heads and lamp holders according to the actual needs of users. This undoubtedly increases the production cost of the lamp. At the same time, if the components included in the light source assembly are damaged during the use of the lamp, the other compatible components cannot be adapted to other models of components, resulting in low efficiency of individual lamp holders, lamp heads and light sources. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a light source with strong adaptability and universal effect.

[0005] To address the above problems, the present invention provides the following technical solution:

[0006] A general-purpose light source, comprising:

[0007] Light source components;

[0008] A lamp holder assembly is disposed on one side of the light source assembly along a first direction, and the lamp holder assembly includes a lamp holder base;

[0009] The lamp holder includes a connector for connecting to an external lamp holder and copper pins disposed around the connector. Anti-detachment protrusions are provided on both opposite outer walls of the connector.

[0010] The side of the connector facing away from the light source assembly is recessed inward along the first direction to form a hollow groove, which is used to connect to an external lamp holder.

[0011] The lamp holder also includes a locking protrusion installed in the hollow groove, which is used to limit the position of the external lamp holder.

[0012] Furthermore, the copper needles are provided in multiples, and the multiple copper needles are arranged along the second direction on both sides of the connector, and the number of copper needles on one side of the connector is equal to the number of copper needles on the other side of the connector;

[0013] The second direction is perpendicular to the first direction.

[0014] Furthermore, the locking protrusion includes a base plate, a locking post protruding along a first direction, and locking strips disposed on both sides of the locking post along a second direction, wherein the locking post and the locking strips are both disposed on the base plate.

[0015] Furthermore, the length of the positioning post extending from the substrate along the first direction is less than the distance from the substrate along the first direction to the opening of the hollowed-out groove.

[0016] Furthermore, the locking strip is disposed on both sides of the locking post along the second direction; the anti-detachment protrusion is disposed on the outside of the connector along the third direction;

[0017] The third direction is perpendicular to the first direction and the second direction.

[0018] Furthermore, the connector also includes a guide groove and a locking groove disposed on the inner sidewall; the locking protrusion includes a support plate disposed on the other side of the base plate opposite to the locking post and a hook disposed at the end of the support plate;

[0019] The substrate has a first protrusion extending out in a third direction. The first protrusion is adapted to the guide groove. The hook is adapted to the engaging groove to prevent the locking protrusion from disengaging from the hollow groove.

[0020] Furthermore, the guide groove and the engaging groove are coplanar on the inner sidewall of the connector, and the guide groove and the engaging groove are spaced apart to form a second protrusion;

[0021] A limiting groove is formed between the first protrusion and the hook, and the limiting groove is adapted to the second protrusion.

[0022] Furthermore, the lamp head assembly also includes a housing disposed on the outside of the lamp head base, and the light source assembly includes a switch circuit board disposed on the housing and a DIP switch mounted on the switch circuit board.

[0023] Furthermore, the light source assembly also includes a control board electrically connected to the DIP switch, and the control board has at least five control levels.

[0024] Furthermore, the light source assembly also includes a top light source, a heat sink, and side light sources. Multiple side light sources are provided, surrounding the heat sink. The top light source is disposed at the end of the heat sink along a first direction.

[0025] The top light source, the side light source, and the heat sink are all in contact with each other;

[0026] The lamp holder is disposed at the other end of the heat sink along a first direction away from the top light source.

[0027] The beneficial effects of this invention are as follows: By setting two pairs of opposing positive and negative copper pins on the lamp holder, and simultaneously setting a connector at the center of the four copper pins, the lamp holder 211 can be connected to an external lamp holder. Furthermore, by designing the connector 221 as a square structure with a hollowed-out center along the first direction, this hollowed-out structure replaces the traditional locking protrusion in the center of the lamp holder, allowing the lamp holder 211 to be compatible with various lamp holders such as the traditional G24q-(1-7), thus improving the versatility of the lamp holder 211. In addition, by setting anti-detachment protrusions 231 on the opposite outer walls of the connector 221, all traditional G24q-(1-7) lamp holders can be matched with these anti-detachment protrusions 231, thereby improving the stability of the lamp holder and making the light source applicable to various traditional lamp holder models, enhancing the practicality of the light source and achieving a multi-purpose effect.

[0037] For ease of description of the first and second directions in the embodiments of this application, the first direction is the up-down direction in the figures, the second direction is the front-back direction in the figures, and the third direction is the left-right direction in the figures. The y-axis arrow direction is referred to as the "up" direction, the z-axis arrow direction as the "back" direction, and the x-axis arrow direction as the "right" direction, but these are not the sole limitations in the actual application of this application.

[0038] Please refer to Figure 1-5 As shown, this embodiment provides a general light source 100, which includes: a light source assembly 110 and a lamp head assembly 210 disposed on one side of the light source assembly 110 along a first direction; in this embodiment, the light source assembly 110 includes a top light source 111 and a side light source 112.

[0039] like Figure 2As shown, optionally, the light source assembly 110 also includes a top light-transmitting cover 113 disposed on the top light source 111, a side light-transmitting cover 114 disposed outside the side light source 112, a switch circuit board 121 disposed in the connecting plate 213, and a DIP switch 122 disposed on the switch circuit board 121. In this embodiment, the top light-transmitting cover 113 and the side light-transmitting cover 114 enclose a receiving space 11a. The light source assembly 110 also includes a heat sink 131 disposed in the receiving space 11a and in contact with both the top light source 111 and the side light source 112.

[0040] In the above scheme, multiple side light sources 112 are provided, and the multiple side light sources 112 surround the heat sink 131. The top light source 111 is provided at the end of the heat sink 131 along the first direction, and the top light source 111, the side light sources 112 and the heat sink 131 all abut against each other, thereby dissipating heat.

[0041] Please refer to Figure 1-2 As shown, in this embodiment, the lamp head assembly 210 is connected to the other end of the side light source 112 away from the top light source 111. Specifically, the lamp head assembly 210 includes a lamp head base 211, a lamp head base cover 212 covering the lamp head base 211 near the side light source 112, and a connecting plate 213 that snaps together the lamp head base cover 212 and the side light source 112. The connecting plate 213 is used to connect the entire general light source 100. In addition, the lamp head base 211 includes a connector 221 for connecting an external lamp holder and copper pins 222 disposed around the connector 221. The side of the connector 221 facing away from the light source assembly 110 is recessed inward along a first direction to form a hollow groove 115. The hollowed-out groove 115 is used to connect to the external lamp holder; in addition, anti-detachment protrusions 231 are provided on the two opposite outer side walls of the connector 221; in this embodiment, multiple copper needles 222 are provided, and the multiple copper needles 222 are arranged along the second direction on both sides of the connector 221. In this embodiment, the copper needles 222 are set in two pairs opposite each other, one pair is the positive electrode and the other pair is the negative electrode, so that the number of positive copper needles 222 and negative copper needles 222 are the same, thereby connecting to the external power supply for power supply and lighting; furthermore, the lamp holder 211 also includes a locking protrusion 232 installed in the hollowed-out groove 115, and the locking protrusion 232 is used to limit the external lamp holder.

[0042] Understandably, this embodiment provides two pairs of opposing positive and negative copper pins 222 on the lamp holder 211, and a connector 221 at the center of the four pins 222, allowing the lamp holder 211 to be connected to an external lamp holder. Furthermore, by designing the connector 221 as a square structure with a hollowed-out center along the first direction, this hollowed-out structure replaces the traditional locking protrusion in the center of the lamp holder, making the lamp holder 211 compatible with various lamp holders such as the traditional G24q-(1-7), thus improving its versatility. In addition, the anti-detachment protrusion 231 on the opposing outer walls of the connector 221 ensures that all traditional G24q-(1-7) lamp holders can be matched with this anti-detachment protrusion 231, thereby improving the stability of the lamp holder 211. This allows the light source to be used with various traditional lamp holder models, enhancing the practicality of the light source and achieving a multi-purpose lamp effect.

[0043] Optionally, the anti-detachment protrusion 231 is disposed in the center of the outer side wall of the connector 221 along a third direction, which has a better locking effect.

[0044] Please refer to Figure 3-5 As shown, according to the above scheme, in this embodiment, the lamp holder 211 further includes a locking protrusion 232 installed in the hollow groove 115. The connector 221 has a locking groove 241 that cooperates with the locking protrusion 232 on its inner sidewall along the third direction. In this embodiment, the locking protrusion 232 includes a base plate 250, a locking post 251 protruding along the first direction, and locking strips 252 disposed on both sides of the locking post 251 along the second direction. The locking post 251 and the locking strips 252 are both disposed on the base plate 250. In addition, the length of the locking post 251 extending from the base plate 250 along the first direction is less than the distance from the base plate 250 to the opening of the hollow groove 115 along the first direction. This structure is such that when the light source is installed on any of the external lamp holders of model G24q-(1-7) through the lamp holder 211, The lamp holder 211 is installed on the external lamp holder by inserting the locking post 251 into the external lamp holder and making the two locking strips 252 on both sides of the locking post 251 abut against the external lamp holder. At the same time, the copper pin 222 is inserted into the copper pin hole of the external lamp holder to form a passage. In one embodiment, it can be understood that the length of the locking post 251 is less than the distance of the hollow groove 115 so that the locking post 251 abuts against the external lamp holder in the hollow groove 115. At the same time, when the lamp holder of G24q-5 is selected for installation, since the lamp holder of G24q-5 has an arc-shaped fastener, by designing the locking post 251 to cooperate with the arc-shaped fastener, the arc-shaped fastener on the lamp holder just surrounds and wraps around one end of the limiting post. At the same time, both sides of the arc-shaped fastener abut against the locking strips 252, thereby improving the installation stability of the lamp holder 211.

[0045] Please refer to Figure 1 and Figure 3As shown, according to the above scheme, in this embodiment, the locking strip 252 is arranged on both sides of the locking post 251 along the second direction; the anti-detachment protrusion 231 is arranged on the outside of the connector 221 along the third direction; this structure makes the installation direction of the locking strip 252 and the installation direction of the anti-detachment protrusion 231 perpendicular to each other in the same plane. This structure is such that when the lamp holder 211 is installed on any lamp holder in G24q-(1-7), the lamp holder 211 has a locking effect with the lamp holder in both directions in the same plane, thereby improving the stability of the lamp holder 211.

[0046] Please refer to Figure 3-5 As shown, preferably, the connector 221 further includes a guide groove 240 and a locking groove 241 disposed on the inner side wall; the locking protrusion 232 includes a support plate 253 disposed on the other side of the base plate 250 away from the locking post 251 and a hook 254 disposed at the end of the support plate 253.

[0047] Optionally, the support plate 253 is made of elastic plastic.

[0048] In the above scheme, the guide groove 240 and the engaging groove 241 are coplanar on the inner sidewall of the connector 221. The base plate 250 protrudes a first protrusion 243 in a third direction, which is adapted to the guide groove 240. The hook 254 is adapted to the engaging groove 241. In addition, a limiting groove 242 is formed between the first protrusion 243 and the hook 254. And a second protrusion 244 is formed between the guide groove 240 and the engaging groove 241 at intervals. The limiting groove 242 and the... The second protrusion 244 is adapted; when the locking protrusion 232 is installed on the lamp holder 211, the first protrusion 243 slides into the hollow groove 115 through the guide groove 240, and then the hook 254 is deformed by the abutting force of the second protrusion 244 and abuts into the locking groove 241, so that the hook 254 hooks the locking groove 241. In this state, the second protrusion 244 and the limiting groove 242 are engaged with each other, thereby preventing the locking protrusion 232 from falling out of the hollow groove 115.

[0049] Please refer to Figure 2-5As shown, preferably, the lamp holder assembly 210 also includes a housing 261 disposed outside the lamp holder base 211. In this embodiment, the switch circuit board 121 and the DIP switch 122 mounted on the switch circuit board 121 are both fixed on the housing 261. Further, the light source assembly 110 also includes a control board 271 electrically connected to the DIP switch 122. In this embodiment, the control board 271 has at least five control positions. It can be understood that by electrically connecting the control board 271 to the DIP switch 122, multiple color temperature lighting devices can be adjusted at any time when the whole lamp is lit. The principle is to achieve the desired color temperature effect by matching the brightness ratio of the lowest and highest color temperatures on the top light source 111 and the side light source 112. The current ratio of the two light sources is allocated by installing a control chip on the control board 271 to achieve the luminous brightness, thereby realizing the adjustment of multiple color temperature lighting effects.

[0050] In summary, this invention provides a universal light source. By setting two pairs of opposing positive and negative copper pins on the lamp holder, and placing a connector at the center of the four copper pins, the lamp holder can be connected to an external lamp holder. Furthermore, by designing the connector as a square structure with a hollowed-out center along a first direction, this hollowed-out structure replaces the traditional locking protrusion in the center of the lamp holder, allowing the lamp holder to be compatible with various lamp holders such as the traditional G24q-(1-7), thus improving the lamp holder's versatility. In addition, by setting anti-detachment protrusions on the opposite outer walls of the connector, all traditional G24q-(1-7) lamp holders can be matched with these anti-detachment protrusions, thereby improving the stability of the lamp holder. This makes the light source applicable to various traditional lamp holder models, enhancing the practicality of the light source and achieving a multi-purpose effect.
